Product Introduction
Service Promise
Ordering Process

Pipe valve is the fifth generation of new product after the old manual control valve, hydraulic butterfly valve, multi-functional hydraulic valve and hydraulic automatic valve. Through the fluid design of the valve, a straight-line flow channel is formed with low energy consumption, stable operation and good sealing effect. It has the functions of electric gate valve, electric butterfly valve and check valve. By increasing the fast closing time, the harm of water hammer can be eliminated and the safety of the pump and pipe network system can be protected. Pipe force valve is mainly used in centrifugal pump, mixed flow pump and axial flow pump outlet pipe of automatic water supply and drainage pumping station. Piston type and diaphragm type control devices are designed, which can be applied to clean water, raw water medium, sewage and slurry water medium respectively. In terms of product type, the company has developed five specifications, such as ordinary type, low-pressure type of backwater, sewage type, to meet the needs of different customers under different working conditions. Because of its compact structure, small volume and light weight, it is especially suitable for large diameter pipeline system. It can be widely used in power supply, environmental protection, metallurgy, petrochemical, water department, municipal, food and other industries, drainage system, sewage pump room, chemical fluid transmission system, is the latest domestic and foreign structure, the most advanced performance, the most reliable operation of the new pump station control equipment.

Characteristic

(1) The valve is composed of upper and lower carbon steel body, rubber pipe sleeve, valve stem gate plate, upper and lower guide posts and other parts.

(2) Working Principle: When the handwheel is rotated forward, the large and small stem simultaneously drives the upper and lower stubble plates, compresses the sleeve and closes, otherwise opens. In this way, the valve is opened and closed from top to bottom reciprocally between the guide posts.

Application condition

In some cases with more sediment and debris (such as Yellow River water quality, sewage treatment system, etc.), the valve control pipeline is easy to be blocked, resulting in valve failure; large debris is also easy to lock the valve plate, resulting in valve seal is not strict; there are also some special conditions, valve switch when the water hammer is very large, resulting in valve switch when loud. Big and even cause accidents.
