Product Description

Working principle

Opening process: When operating the hand wheel (manual operation) or through the electric, pneumatic and other driving devices to drive the valve stem upward movement, the valve stem drives the gate to rise. The gate leaves the elastic seat, the valve channel opens, and the medium can pass through the valve smoothly. In this process, due to the rise of the gate, the elastic seat gradually returns to its original state.

Closing process: Reverse operation, the valve stem drives the gate down. The gate is gradually close to the elastic seat, when the gate and the elastic seat contact, continue to apply pressure, the elastic seat under the extrusion of the gate deformation, tightly fit between the gate and the valve body, thus cutting off the flow channel of the medium, to achieve sealing.

Performance characteristics

Good sealing performance: Thanks to the flexible seat, this gate valve can effectively prevent media leakage when closed. Even under low pressure conditions, the elastic seat deforms enough to fill the seal gap, providing a reliable seal for both liquid and gaseous media. For example, in the water supply system, it can effectively prevent water leakage.

Wear resistance and corrosion resistance: the ram and valve body material itself has a certain wear resistance and corrosion resistance, coupled with the special treatment of the ram surface, can adapt to the media containing certain impurities. The choice of elastic seat material also considers corrosion resistance, such as EPDM rubber can withstand a certain chemical medium erosion, extend the service life of the valve.

Suitable for a variety of media and working conditions: can be used for water, oil, steam and other media transportation. Under different pressure and temperature conditions, as long as the appropriate body material and elastic seat material is selected, it can work normally. For example, in the chemical pipeline system, for some chemical raw materials that are not corrosive, it can play its good sealing and flow control function.

Better flow characteristics: similar to ordinary gate valves, when the medium flows through the valve, because the channel is basically straight through, the fluid resistance is small, and the flow coefficient is large. In the full open state, it can achieve a larger flow rate, which is conducive to improving the operating efficiency of the pipeline system.

Application field

Municipal engineering: widely used in urban water supply and drainage systems. It is used to control the amount of water in the water supply pipeline and the discharge of sewage in the drainage pipeline to ensure the normal operation of the urban water supply and drainage system.

Construction field: used in the water supply and drainage system and fire fighting system of buildings. For example, in the fire hydrant system, as a control valve, to ensure that fire water can be timely and accurate supply.

Industrial field: In the pipeline system of chemical, petroleum, electric power and other industrial industries, it is used to transport various industrial media. Such as crude oil and refined oil transportation pipelines in refineries, raw materials and product transportation pipelines in chemical plants, etc., to play its flow control and sealing functions.
