What are the advantages of flanged electric cast steel switch gate valve?

The pneumatic pinch valve produced by Wuhu Naide Hose Valve Industry has excellent wear resistance and anti-corrosion performance, and its lining of special rubber has excellent performance in various properties. With wear-resistant, anti-corrosion and high-temperature resistant rubber as the lining layer, the physical and chemical properties of the rubber itself reduce the effect of the pipeline conveying medium on the external structure, such as impact force, corrosion, etc., due to the cushioning effect of rubber, greatly prolong the service life of the pipeline, reduce the cost of users. Wuhu Naide hose valve industry has nearly 20 years of valve research and production experience, and has close cooperation with major domestic mines and power plants.

The main points are as follows.

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section of the same length.

2. Simple structure, small size and light weight.

3. Tight and reliable, the sealing surface material of the gate valve is widely used plastic, with good sealing, and has been widely used in the vacuum system.

4. Easy to operate, fast opening and closing, from full open to full closed, only need to rotate 90°, which is convenient for long-distance control.

5. Easy maintenance, simple structure of gate valve, sealing ring is generally movable, and it is more convenient to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the gate body and the valve seat is isolated from the medium, and the erosion of the sealing surface of the valve will not be caused when the medium passes. Hazelnut Electromechanical is quite good.

7. Wide range of application, from small to a few millimeters in diameter, from high vacuum to high pressure. When the ball rotates 90 degrees, the sphere should be fully present at the inlet and exit, thus cutting off the flow.

Electric valve: used for analog adjustment of the flow rate of the pipeline medium in the liquid, gas and wind system, which is controlled by AI. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.

Electric valve: can have AI feedback signal, can be controlled by DO or AO, compared to large pipes and dampers, etc.

1.Switch form:

The drive of the electric valve is generally driven by a motor, and it takes a certain amount of time to complete the opening or closing action, which can be adjusted.

2.Nature of work:

The electric valve is generally driven by a motor, which is more resistant to voltage shock. The solenoid valve is quick to open and close quickly, and is generally used in places with small flow and low pressure, and requires a large switching frequency. The opening of the electric valve can be controlled, and the state is open, closed, half-open and half-closed, which can control the flow of the medium in the pipeline and the solenoid valve cannot meet this requirement.

3.Applicable process:

Electric valves are generally used for adjustment, but also have switching quantities, such as the end of the fan coil unit.

(1) The valve adopts pressure self-tightening sealing or valve body and bonnet gasket sealing structure, which is safe and reliable to use. (2) The valve disc adopts a universal top structure with a double ram in the middle, which can automatically adjust the consistency between the valve disc and the sealing surface of the valve seat to ensure the sealing of the valve. At the same time, this structure is easy to maintain, and the valve disc is interchangeable.

3) The electric device is equipped with a torque control mechanism, an on-site operation mechanism and a hand, and an electric switching mechanism. In addition to local operation, it can also carry out long-distance operation, PLC control, 4 20mA current input and output intelligent control, etc. (4) The manual valve is opened by a manual mechanism or a handwheel when it is impacted, which reduces the operating force of the valve.

5) The valve can be installed in any position of the pipeline, and at the same time, carbon steel or alloy steel valve can be selected according to the temperature of the medium and the medium.

An electric valve simply means that the valve is controlled with an electric actuator, so that the valve can be opened and closed. It can be divided into two parts, the upper part is the electric actuator, and the lower part is the valve.

There are two kinds of electric valves, one is the quarter-turn electric valve: the quarter-turn electric actuator is used with the quarter-turn valve to realize the valve within 90 degrees to control the pipeline fluid on-off; The other is the linear electric valve: the linear electric actuator is used with the linear stroke valve to realize the up and down action of the valve plate to control the flow of the pipeline.

It is usually used in conjunction with equipment with a high degree of automation.

Light weight: The body is made of high-grade ductile black cast iron, which is about 20% 30% lighter than the traditional gate valve, and is easy to install and maintain.

Flat-bottomed gate seat: The traditional gate valve is often accumulated in the groove of the bottom of the valve due to the accumulation of foreign objects such as stones, wood, cement, iron filings, sundries, etc., after the water is washed, and the bottom of the elastic seat seal gate valve adopts the same flat-bottom design as the water pipe, which is not easy to cause the accumulation of debris caused by empty wax traces, so that the fluid is unimpeded.

Overall rubberization: The ram is made of high-quality rubber for the overall inner and outer rubber, and the first-class rubber vulcanization technology in Europe makes the vulcanized ram can fight and ensure accurate geometric dimensions, and the rubber and ductile cast ram are firmly connected, not easy to fall off and have good elastic memory.

Precision cast valve body: The valve body is made of precision casting, and the precise geometric dimensions make the valve body without any finishing to ensure the tightness of the valve.
