An electric gate valve is a kind of widely used valve, which is mainly used in analog control of liquid, gas and air system pipeline medium flows. It is controlled by AI. In the control of large valves and air systems, electric valves can also be used as two position switch controls. Let's take a look at the working principle of electric gate valves. The working principle of the electric gate valve is that the electric gate valve is usually connected by the electric actuator and the valve, and...

Here is some info about the disadvantages, common faults and maintenance of gate valves. 1. Disadvantages of gate valves Erosion and abrasion are easily caused between sealing surfaces of a gate valve, and the maintenance is difficult. It has a large size, which requries a certain space to be opened and closed, and it has a long opening and closing time. Besides, the structure is complex. 2. Packing leakage and treatment methods of gate valves If the packing is aged and causes leakage,...

When it comes to a gate valve, we should all be familiar with it. In short, a gate valve is a gate with opening and closing parts, and its movement direction and fluid direction are perpendicular to each other. In addition, the gate valve can only be fully opened or fully closed, and it can not be adjusted or throttled. However, people have been puzzled about the expression method and the meaning of gate valve models. A gate valve is a common type of shut-off valve, and it is generally...

A summary of valve knowledge 1. Gate valves Working principles: there are gate opening and closing parts inside the valve body. The movement direction of the gate is perpendicular to the direction of the fluid. Because water can be blocked like the water gate, it is named a gate valve. Scope of applications: gate valves are used for water outlet pipes and suction pipes of fire pumps, water outlet pipes and suction pipes of stabilized pressure pumps and fire water supply pipelines....

1. Features of gate valve Gate valves refer to the valve whose plate move in the vertical direction along the path centerline. A gate valve is mainly used for cutting off the medium in pipelines. A gate valve is a kind of widely used valve. Generally, it is selected as the cutting device with a DN greater than or equal to 50mm, and sometimes it is also selected as the cutting device with small calibers. Gate valve has the following advantages: 1. The fluid resistance...

Block valves are mainly used to block or connect the medium flow, which includes gate valves, globe valves, diaphragm valves, ball valves, plug valves, butterfly valves, plunger valves and ball plug valves. Regulating valves are mainly used to regulate the flow and pressure of the medium, which include regulating valves, throttle valves and reducing valves. Check valves are used to prevent backflows of media. Check valves have various structures. Diverter valves are used to separate, distribute or...

A valve is a mechanical device that controls the flow, flow direction, pressure and temperature of the flowing fluid medium. It is the basic component of the pipeline system. Then, let's learn about the ball valve as well as its advantages and disadvantages. A ball valve is evolved from a plug valve. Its opening and closing parts are like a ball. The ball is rotated by 90 degrees around the axis of valve stems to achieve the purpose of opening and closing. A ball valve is...

The opening and closing part of a ball valve is a ball with a circular channel, which rotates around the axis perpendicular to the channel. The ball rotates with the valve stem to achieve the purpose of opening and closing the channel. Ball valves can be closed with only 90 degree rotations and a small torque. According to the requirements of the operating conditions, different driving devices can be assembled to form a variety of different control methods of ball valves such as electric...
