Types of Pneumatic Drive Type Butterfly Valve Accessories

In the process of using Pneumatic Drive Type Butterfly Valve, some auxiliary parts are usually required to improve the performance of pneumatic valve, or to improve the efficiency of pneumatic valve. Common pneumatic valve accessories include: air filter, commutation solenoid valve, limit switch, electrical locator, etc. Pneumatic technology, air filter, pressure reducing valve, oil mist device together three air processing elements, is called a pneumatic triple a, to entering the air purification filter and decompression of the pneumatic instrument to instrument rated supply air pressure, the function of the equivalent circuit of power transformer.

Structural Features Of Bellow Seal Globe Valve

Bellow Seal Globe Valve are valves used to control flow. It has the following structural features:

1. Double seal design (corrugated pipe + packing) if bellows fail, stem packing will also be avoided.

2. Reasonable structure, reliable sealing, excellent performance and beautiful shape.

3. No fluid loss, reduce energy loss and improve plant equipment safety.

4. Surfacing welding Co - based hard alloy with dense cover, wear-resisting, anti-corrosion, good anti-friction performance, long service life, less maintenance times and lower operating costs.

5. Strong and durable bellows seal design ensures zero leakage of stem, providing conditions without maintenance.

6. The globe valve stem has good anti-corrosion and anti-friction performance in adjusting quality and surface nitrogen treatment;

7. The valve stem lifting position indicator is more intuitive.

How much do you know about the Motorized Globe Valve?

 Motorized Globe Valve and flanged gate is belong to one and the same type of valve consists of electric actuators or pneumatic actuators and globe valve in two parts. The difference in its closure is a valve body, valve body around the center line of the body as a rotation to achieve a kind of open and close the valve. Gate valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two - chip ball valve, three - chip ball valve, is a new valve widely used in recent years.

Additional the Angle Globe Valve that a lot of people say is called triangle valve again, horn shape valve, water valve that fold Angle, it is used to decorate the hydroelectricity installation of industry more, it is important water warm fittings. Its structure and characteristics are modified by ball valve.

Valve Basic Knowledge

 The valve is the control device of the fluid pipeline. Its basic function is to connect or block the flow of the pipeline medium, change the flow of the medium, change the direction of movement of the medium, regulate the pressure and flow of the medium, and protect the normal operation of the pipeline equipment.

With the continuous development of modern industry, the demand for valves continues to grow, like cast steel ball valve, casting steel-static ball valve and a modern petrochemical installation requires tens of thousands of valves, with a large amount of valves. Frequent opening and closing, but often because of production, the use of selection, repair is not appropriate, there will be running, dripping, missing images, resulting in flames, blasting, poisoning, hot bad things, may form a poor product quality, energy consumption progress , equipment corrosion, material consumption, environmental pollution, and even stop production. Therefore, everyone expects to obtain high quality valves.

 

What Are The Structural Features Of The Gate Valve?

 The gate valve has the characteristics of low fluid resistance, applicable pressure, large temperature scale, etc. It is the most commonly used shut-off valve used to cut off or connect the medium in the pipeline. The following are the specific features:

1.Light weight: The main body is made of high-grade ball black cast iron, and the weight is reduced by about 20%~30% compared with the traditional valve components, and the device is easy to repair.

2.The overall plastic package: gate selection of high-quality rubber for the overall internal, outsourced rubber, the European first-class rubber vulcanization skills allow vulcanized gate to ensure accurate dimensions, and rubber and ball-casting gate then reliable, not easy Drops and elastic memories are good.

3.Flat-Bottomed gate: the traditional gate valve is usually in the water after the tube is washed because foreign objects such as stones, wood, cement, iron, debris, etc. deposited in the bottom of the valve groove, simply formed can not close tight and form a leak Phenomenon, the bottom of the elastic seat sealing gate valve is the same as that of the water pipe machine, and it is not easy to form debris deposits, so that the fluid is unobstructed.

4.Casting valve body: The valve body of gost gate valve is made of precision forging. The exact dimensions allow the valve body to ensure the sealing of the valve without any finishing.
