The Overview of Light Gate Valve

The flat plate gate valve is a kind of single gate plate valve or double gate plate valve with a distraction mechanism. The flat plate gate valve is prone to leakage when the pressure of the medium is low. To ensure good sealing of sanitary valve under full pressure, sufficient preload needs to be applied to the valve seat.

However, when there’s a large preload and the pressure of the medium is high, frequent opening and closing of the valve may make the sealing surface wear too fast, affecting the service life of the valve. Meanwhile, the gate valve usually uses iron cast or steel cast materials, which are very heavy and not suitable for applications on some mobile occasions. Therefore, the light gate valve is designed to reduce the weight of the flat plate gate valve and improve its sealing performance and service life.

As a whole, the valve uses an asymmetrical flat body structure, combining the valve body and valve cover of an ordinary gate valve. The valve body is designed to be a flat square. This kind of design reduces the structural size and volume of the valve body, saves the connecting bolt between the valve body and valve cover, and effectively reduces the weight of the valve.

The valve seat uses an independent design, combining the valve seat and valve interface of an ordinary gate valve. For the same valve body, replacing the valve seat can change the interface of the valve. This effectively improves the versatility and maintainability of the valve body while avoiding the problem of poor sealing effect caused by deformation of the valve body under high pressure.

In order to increase the sealing capacity of gate valve in a low-pressure situation, to solve the leakage problem of gate valve under low pressure while reducing the friction between the gate plate and the sealing ring of the valve seat in addition to improving the service life of gate valve, the sealing of the gate valve is designed to be steel ball-topped mechanical expansion and contraction sealing mechanism.

When the gate valve is closed, the steel ball-topped mechanism props open the two gate plates, presses tight the sealing surface, which produces sealing pressure, achieving the effect of double-sided forced sealing. When the gate valve is open, the steel ball-topped mechanism contracts and the gate plate leaves the sealing surface by moving inward, which reduces the friction between the gate plate and the sealing ring of the valve seat during the process of opening and closing.

The magnetic gate valve opening indicator displays the opening of the gate valve by using the magnet on the gate plate to move the pointer of the magnetic induction meter installed outside the gate valve.

In the case of different openings in the valve, there’re different distances and directions between the magnet installed on the gate plate and the indicating meter, which has induction of different intensity and direction on the magnetic induction pointer of the indicating meter. According to this, the pointer can indicate the different openings of the valve.
