The XZ45X signal elastic seat sealing gate valve is applied to the automatic sprinkler fire pipeline system to monitor the water supply pipeline and can remotely indicate the valve opening. Signal gate valves are commonly used in automatic sprinkler fire pipeline systems to monitor water supply pipelines and remotely indicate valve opening. Rising stem gate valves and gate valves with opening indication are also commonly used in fire protection systems. If the installation position of the gate valve is high above the ground, rising stem gate valves are generally used to clearly indicate the valve opening. If the installation position is low, rising stem gate valves can be used. Then it is necessary to attach an opening indicator gate valve.

The opening and closing component of the XZ45X signal elastic seat seal gate valve is the gate, and the direction of the gate's movement is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. Gongliang valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. The gate valve has two seals, and the two sealing surfaces of the commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50 degrees, and 2 ° 52 'when the medium temperature is not high. The gate of a wedge gate valve can be made as a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation to change its work and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate. Signal gate valves are generally installed horizontally.

The types and sealing surface configurations of XZ45X signal elastic seat sealed gate valves can be divided into wedge gate valves and parallel gate valves. Wedge gate valves can also be divided into single pole, double gate, and elastic gate valves; Parallel gate valves can be divided into single gate plate and double gate plate. According to the thread position of the valve stem, it can be divided into two types: rising stem gate valves and hidden stem gate valves.

When the XZ45X signal elastic seat seal gate valve is closed, the sealing surface can be sealed solely by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to seal the surface, which is self sealing. Most gate valves use forced sealing, which means that when the valve is closed, external force must be used to forcefully press the gate plate against the valve seat to ensure the sealing performance of the sealing surface.

The gate of the XZ45X signal elastic seat sealed gate valve moves linearly with the valve stem, which is called a lift rod gate valve. Usually, there are trapezoidal threads on the lifting rod, and through the nut on the valve and the guide groove on the valve body, the rotational motion is converted into linear motion, that is, the operating torque is converted into operating thrust.

When the valve is opened, when the lifting height of the gate is equal to 1:1 times the valve diameter, the fluid channel flows, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is used as a marker, that is, the position where it cannot be opened, as its fully open position. To consider the phenomenon of locking due to temperature changes, it is usually done by opening the valve to the top position and then reversing it by 1/2-1 turn as the position for fully opening the valve. Therefore, the fully open position of the valve is determined by the position of the gate (i.e. stroke). Some gate valves have the stem nut set on the gate, and the handwheel rotates to drive the stem to rotate, thereby lifting the gate. This type of valve is called a rotary stem gate valve or a concealed stem gate valve.

Construction and installation characteristics of XZ45X signal elastic seat sealing gate valve:

1. The connection method of the valve should be consistent with the connection method of the pipeline.

2. The direction of the arrow on the valve body of the valve set on the unidirectional flow pipeline of the medium should be consistent with the direction of the water flow in the pipeline.

3. When installing the valve horizontally, the valve cover and stem should face upwards; When installed vertically, the valve cover and stem should face outward.

4. Valves should be equipped with brackets, and the weight of the valve should not be attached to the pipeline.
