Anti-condensation Aluminum Butterfly Valve

The principle of the anti-condensation butterfly valve is due to the corrosion resistance of the aluminum alloy body, which is light in weight and easy to install; the spherical structure around the butterfly plate is helpful to reduce the friction torque with the valve seat; the butterfly plate and the valve shaft are made of stainless steel, which increases The anti-corrosion ability also plays a role in reducing heat conduction and preventing the temperature of the driving device from being too low; the housing of the driving device is made of aluminum alloy, which is light in weight and fa

Advantages Of Two Shaft Wafer Type Butterfly Valve

Advantages:1. easy and quick to start and close, labor-saving, low fluid resistance, can be operated frequently2. Simple structure, small size, short structure length, small volume, light weight3. start and close torque is small, because the butterfly plate on both sides of the shaft is basically equal to the action of the medium, and the direction of the torque generated is opposite, so it is relatively labor-saving4. The material of sealing surface generally adopts rubber, plastic, so the low pressure sealing performance is good.5.

Background of Butterfly Valve

Butterfly valve is a type of valve that uses a spherical butterfly plate as the opening and last component and turns with the valve stem to open, close and alter the fluid channel. the butterfly plate of the butterfly valve is set up in the diameter route of the pipe. in the cylindrical channel of the butterfly valve frame, the disc formed butterfly plate rotates around the axis of the valve stem at an perspective among 0 ° and 0 °. whilst the butterfly plate is at 0 °, the valve is closed, and when the butterfly plate is at ninety °, the valve is absolutely opened.

Introduction of Butterfly Valve Characteristics

1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, quick switch, 90 reciprocating rotation and small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline, and has good fluid control characteristics and closing and sealing performance.2. Butterfly valves can transport mud, and the liquid accumulated at the pipe mouth is the least. Under low pressure, good sealing can be achieved. Good adjustment performance.3.

The Differences Between Soft Seal Butterfly Valve And Hard Sear

Hard seal butterfly valve is called "hard seal" when both sides of the seal are made of metal or other hard materials. The sealing function of this kind of seal is poor, but it is resistant to high temperature, wear and tear, and has good mechanical function.

The development trend of electric butterfly valve

Electric butterfly valve means that the butterfly valve is equipped with an electric actuator, which controls the opening and closing of the valve through the electric energy provided by the power supply, so as to realize remote centralized control and automatic operation. Electric butterfly valve can be divided into flange type and disc type according to the connection method, which is an important execution unit in the field of industrial automation control.

Common Check Valve Materials

Check valve is a valve installed in the pipeline to prevent the backflow of media. Check valves can be used on many types of pipelines such as over water, oil and gas, etc.

Introduction of Slient Check Valve Wafer Type

Test valve refers to the hole and remaining elements of the circular disc and with the aid of its own weight and media stress generated motion to block the media float lower back valve. automatic valve elegance, additionally referred to as test valve, one-way valve, backflow valve or isolation valve. disc movement is split into lifting and swing. elevate test valves are comparable in creation to globe valves besides for the stem that drives the disc. the medium flows in from the inlet quit (decrease side) and flows out from the hole give up (higher aspect). valve

Pressure test method of check valve

Check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.

The principle of check valve opening and closing

The check valve opening and closing parts are opened or closed by themselves by the flow and force of the medium to prevent the backflow of the medium. The valve is called a check valve. The check valve belongs to the automatic valve category, which is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents. The check valve, also known as a one-way valve or a check valve, is used to prevent the backflow of the medium in the pipeline.

The meaning of butterfly valve and the problems that are easily overlooked in the use process

In production and life, the emergence of valves is that the utilization rate of their valves and accessories is getting higher and higher, such as check valves, check valves, electric butterfly valves, pneumatic butterfly valves, rubber soft joints, electric ball valves, one-way valves, and wafer butterfly valves. , filter, etc., which have brought great convenience to production and life.
