The main structural features of the Ball Check Valve can be called a check valve, in use can effectively prevent the pipeline in the medium back, check valve is automatic valve class, in the installation Mainly installed in the pipe can make a one-way flow of the pipeline, so as to ensure that the media flow in one direction, to avoid the return process in the process of accidents and accidents, then, for the Ball Check Valve in the use of what Structural features
1, the ball-type check valve structure length and other traditional flange check valve is shorter, generally only their 1/4 ~ 1/8 or so, for the installation and use of personnel to bring more convenience
2, the ball valve check valve in the closure of the speed is very fast, and the water hammer pressure is relatively small, relatively light weight, only the traditional micro-resistance slow closing check valve about 1/4 ~ 1/20 weight, The installation of Ball Check Valve construction personnel to save more time,
3, check valve The overall structure is simple and compact, and handsome in appearance, in the course of use to ensure smooth flow, fluid resistance is small, with a very good sealing performance characteristics, long life, high reliability
Ball Check Valve superiority
First of all, the ball-type check valve energy-saving effect is very good, usually energy-saving waterproof hammer no wear ball-type check valve annual power savings to reach 32000-55000 degrees, than the micro-resistance slow closing check valve and swing check valve The effect of electricity is better; secondly, its role in the waterproof hammer is also very prominent, through a certain comparison test proved that energy-saving waterproof hammer no wear Ball Check Valve water shock wave intensity is less than about twice the swivel check valve , In addition to the occurrence of a destructive water hammer; in addition, its life is very impressive, even up to ten years without maintenance, Ball Check Valve is not the so-called joint parts, there is no relative mechanical conflict Movement, so there is no wearing parts, which naturally increases its service life. Has a good sealing performance, can be widely used in water, net water, turbid water and other media; modified rubber raw materials can also be used for other liquid media. Not only that, but also easy to repair, check valve If you want to clean the internal foreign body or replace the rubber ball, then the ball can be removed from the maintenance hole or loaded.
Soft seal gate valve characteristics of knowledge:
1. The valve can be designed for flange connection and clip connection.
2. Drive mode can choose manual, electric or pneumatic.
3. Compact and lightweight, easy to disassemble and repair, and can be installed in any location.
4. Simple structure, compact, small operating torque, 90 degrees turn open quickly.
5. Flow characteristics of a straight line, good regulatory performance.
6. The connection of the butterfly plate to the stem uses a pinless construction that overcomes the possible leaks.
7. Seal can be replaced, and the seal is reliable to achieve two-way seal.
8. Butterfly plate can be sprayed according to user requirements, such as nylon or polytetrafluoroethane.
