Plunger Valve Working Principle

A plug body with a through hole is used as a valve for an opening/closing member of a plunger valve in China Famous Valves. The plug body rotates with the valve stem to open and close.

The plug body of the plunger valve is mostly a cone body (also has a cylinder body), and the conical hole surface of the valve body cooperates with a seal pair. The plunger valve is the earliest type of valve, with a simple structure, rapid switching, and low fluid resistance.

The ordinary plunger valve is sealed by the direct contact between the finished metal plug body and the valve body, so the sealing performance is poor, the opening and closing force is large, and it is easy to wear. Usually it can only be used for low pressure (not higher than 1 MPa) and small Caliber (less than 100 mm) occasions.

How To Fix The Butterfly Valve?

  When something goes wrong, butterfly valve must be repaired in time. Repairs of cast iron butterfly valve you wholesale should pay attention to the following points:

1. When the butterfly valve hydraulic drive equipment is faulty, repair personnel should be found to find the problem in time and repair it.

2. When the parts in the equipment are replaced, the oil in the accumulator should be brought out first to avoid the onset of the incident.

3. When replacing the electrical parts, the power should be closed in time to avoid the occurrence of electric shock.

4. When repairing, check whether the strength and hardness of the screws are up to the rules of the manufacturer.

How To Protect And Repair The Butterfly Valve?

 The protection of butterfly valve hydraulic drive equipment is essential for everyday life. The main aspects of repair are:

1. After the butterfly valve hydraulic equipment is completed, add certain oil to the equipment according to the instructions. The new oil is filtered before it can participate in the fuel tank. So does the 10K swing wafer butterfly valve.

2, when it is the initial operation, admit the direction of the motor is not accurate.

3, after the initial operation, the pressure in the accumulator should use nitrogen, must not use oxygen, because it is so easy to attack explosion.

4, we should always check the machine's various parts if it is normal and damaged, if it is not normal, replace in a timely manner to avoid the incident.

5, there is a fault indication, oil spills and other abnormal phenomena, we must promptly review, if you found problems, timely repairs.

Ball Valve Highlights

  Ball valves have many advantages. Did you know about them? Let's take a look:

1. The repair is convenient, the structure of the ball valve is simple, the seal ring is usually active, and the disassembly and replacement are comparatively convenient;

2. When fully open or fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium, and the medium will not cause erosion of the valve sealing surface.

3. The ball valve such as gost carbon steel stainless steel ball valve has a wide range of applications, ranging from small to several millimeters in diameter to as large as 1.2 meters. It can be applied from high vacuum to high pressure.

Four Advantages Of Ball Valve

  The ball valve is one of the most widely used valves. The following are the four advantages of the ball valve.

1. The fluid resistance is small, and the resistance coefficient is the same as that of the same length.

2, Simple structure, small size, and light weight, like 10K ball valve.

3, Tight and reliable, now the ball valve sealing surface data widely used plastic, good sealing, has also been widely used in the vacuum system.

4, Easy to operate, open and close agile, from full open to full off just rotate 90 °, easy to remote control.

 

Ball Valve Is The Most Widely Used In The Valve Industry

  The ball valve in the top industrial valves is the most widely used. The ball valve has the action of rotating 90 degrees. The plug body is a sphere, and has a circular through hole or passage through the axis. In the pipeline, the ball valve is mainly used for blocking, distributing and changing the direction of movement of the medium. It only needs to be closed tightly with a 90 degree rotation and a small rolling moment. The ball valve is the most suitable for use as a switch or block valve.

The ball valve can be divided into raw materials: carbon steel ball valve, cast steel and stainless steel ball valve, 316 ball valve and copper ball valve and cast iron ball valve. It is widely used in petroleum, chemical, power generation and other departments, stainless steel as raw materials, stainless steel ball valve has a strong anti-corrosion features, simple structure, tight and reliable features.

The Principal Application Area Of The Valve

  1. In environmental protection application valves and domestic environmental protection systems, the water supply system mainly needs the midline butterfly valve, the soft seal gate valve, the ball valve, and the exhaust valve (used to exclude the air in the pipeline). Sewage treatment systems mainly use soft seal gate valves and butterfly valves.

2. Valves for gas and city gas account for 22% of the entire natural market. The amount of valves is large, and its types are also numerous. The main need for ball valves, plug valves, pressure relief valves, safety valves.

3. Pipeline valves and long-distance pipelines are mainly crude oil, finished products, and natural pipelines. The valves that require the majority of these pipelines are forged steel three-body full-diameter ball valves, sulfur-resistant flat gate valves, safety valves, and check valves.
