The mud discharge valve is used in the water treatment plant as a sludge and waste water in the discharge tank. The valve has an angled structure and an internal nylon reinforced rubber diaphragm for long-term use of the mud valve . The main parts of the mud valve are: cast iron, stainless steel and nylon reinforced rubber.
At the same time, the main dimensions of the mud valve (flange connection size in accordance with GB4216) are H: 125, 145, 155, 175, 200, 225, 275, 325, 375 DN: 50, 65, 80, 100, 125, 150, Structural features of 200, 250, 300 mud valves The mud valve is also known as a cover valve. It is commonly used for discharging sludge at the bottom of sedimentation tanks in urban water plants and sewage treatment plants. The applicable medium for the mud discharge valve is the primary sewage. The temperature of the medium should generally be less than 50 ° C, and the working water depth is less than 10 meters.
 The mud valve generally has the following structural features: the valve cover has its own screw. When the water depth is shallow, it can be directly operated by the handle; the valve plate is tapered and arched, with its own guiding, and the opening operation force is small; the screw and sealing surface are made of tin bronze. Corrosion and wear resistance. It can be used with the flashlight dual-purpose hoist for microcomputer control.

1. When the ordering, (mud valve) the user should indicate the depth (i.e., the value of H shown) sedimentation tank, to determine the length of the connecting shaft.
2. The operation mode of the mud discharge valve is generally manual type. If the user needs to adopt the electric type, please specify when ordering.
3. The flange dimensions shown in the table are common specifications. If you need special flange size, please specify when ordering. The mud discharge valve, also known as the cover valve, is generally used for discharging sludge at the bottom of the sedimentation tank of urban water plants and sewage treatment plants. The mud valve generally has two types: a hydraulic mud valve and a pneumatic angle mud valve. The main feature of the valve is the use of a dual-chamber diaphragm transmission mechanism instead of a piston type, no motion wear and long life.
 The mud valve product is composed of a hydraulic cylinder and a corner stop valve. The power in the hydraulic cylinder drives the flap to move up and down, so that the valve body passage is opened or closed to achieve fluid continuity. The piston seal of the hydraulic cylinder is an L-shaped bowl, which has good sealing performance and durability. The valve disc and the valve seat are soft sealed, and the sealing performance is good without leakage. ( Discharge valve ) It adopts electric two-position four-way reversing valve or manual two-position four-way reversing valve for centralized control, which is convenient to operate.
The mud discharge valve is generally installed in the water company or other types of pools and pools to eliminate the sediment in the pool at any time. The valve is composed of a valve body, a hydraulic cylinder, a piston, a valve stem and a valve disc, and the hydraulic cylinder is a liquid tool. The liquid acts as a power, and the piston and the valve stem act as switches. It only takes one minute to open the valve plate. This valve must be equipped with a manual valve or solenoid valve to remotely control the mud valve switch. The mud valve has strong sealing performance, flexible switch, convenient maintenance and long service life. Life expectancy can be more than five years.

The liquid level transmitter can convert the changes of various level parameters into analog signals, and transmit them to the control room remotely for centralized display, alarm or automatic control of secondary instruments or computers. Its good structure and installation method can be applied to the continuous detection of liquid level, material level or material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-cold junction, and solid powdery and granular materials. , can be widely used in detection and control in various industrial processes.
Liquid level transmitters can be applied to liquid Level Measurement and control in industrial sites, rural water supply and sewage treatment, petroleum, chemical industry, power plants, hydrological monitoring, reservoirs, dams, hydropower construction and other fields of liquid level measurement and control. Liquid level transmitters have input type, straight rod type, flange type, threaded type, inductive type, screw-in type, floating ball structure design, with anti-blocking type design, simple device, convenient use and strong interchangeability , The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes in the flow or static liquid level, and has high measurement accuracy.
Advantages of Level Transmitters
1. The device is simple, easy to use, and has strong interchangeability.
2. It is suitable for measuring the liquid level and interface of the liquid medium in the container. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and complete detection functions.
3. The reading is intuitive and eye-catching, and the direction of the observation indicator can be changed according to the user's needs.
4. The measurement range is large, not limited by the height of the storage tank.
5. The indicating mechanism is completely isolated from the measured medium, with good sealing performance, high reliability and safe use.
6. Simple structure, convenient installation, convenient maintenance, corrosion resistance, no power supply, explosion-proof.
7. The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes of flowing or static liquid level, and has high measurement accuracy.
8. With intrinsically safe explosion-proof and isolated explosion-proof capabilities, it can be used in various dangerous places.
9. With anti-blocking design, it can realize the measurement of the liquid level of paste medium.
10.100% equal division scale, LED/LCD indicator head, very convenient to read on site.
11.4~20mA two-wire signal transmission, strong anti-interference ability and long transmission distance.
12. Exquisite and unique zero point, full scale, and nonlinear compensation ensure the accuracy and stability of the instrument within the range of operating conditions.
13. The Pressure Sensor directly senses the liquid level pressure and is not affected by the foaming and accumulation of the medium.
14. Wide range of tested media can be used, such as oil, water and paste, with certain anti-corrosion ability.
Classification of liquid level transmitters
1. Single flange liquid level transmitter
Single-flange liquid level transmitters have flat flanges and flange liquid level transmitters with insert barrels, both of which are suitable for single-flange liquid level transmitters that use the gravity of the medium to be measured to measure the height of the liquid level. For medium with high viscosity and easy crystallization, it is generally used in open containers or equipment installations.
2. Double flange liquid level transmitter
The double-flange liquid level transmitter is a Differential Pressure Transmitter, which provides a reliable measurement method to prevent the measured medium from directly contacting the isolation diaphragm of the transmitter. The main features are the need to isolate the high-temperature medium from the transmitter, the measurement medium has a corrosive effect on the sensitive components of the transmitter, the suspension liquid or high-viscosity medium, the measured medium solidifies or crystallizes due to changes in the environment or process temperature, and the measured medium is replaced It needs to be strictly purified to measure the first class. Double flange liquid level transmitter is mainly used in the measurement of liquid level in sealed pressure vessels.
3. Submersible liquid level transmitter
The submersible liquid level transmitter has rod type and arm type. Its principle is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into electricity. Signal. After temperature compensation and linear correction, it is converted into 4~20mA current signal output. Due to the characteristics of this transmitter, such as convenient installation, strong adaptability, etc., it can perform high-precision measurement from water, oil to paste with high viscosity, and is not affected by the foaming and accumulation of the measured medium. It is generally used in open Devices for mouthpieces or equipment.
