A valve is a control component in the fluid transportation system, which has the functions of cutting off, regulation, diversion, prevention of countercurrent, pressure stabilization, shunt and adjustment of medium flow balance. A valve is also one of the most typical equipment in the heat system. The quality of the valve and whether to select a reasonable type according to the characteristics of valves will play a decisive role in the supply heat quality. As the valves are laid in the...

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...
