Who knows which large blind valve manufacturers there are in China. Thank you

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Blind valve is a kind of hand, electric or pneumatic and hydraulic gate valve that cuts off the gas medium, which is generally divided into electric blind valve, hydraulic blind valve, pneumatic blind valve, closed plug-in valve, and electric open blind valve. Cangzhou Shenghong pipe fittings production of blind valve has a total of three driving devices, including two manual clamping or loosening devices, one is to make the ram open or close the electric device, in the opening or closing of the ram, first loosen the two manual devices, and then start the electric device, in order to achieve the purpose of the ram open or close (special attention: the two manual devices are not loosened, shall not open the electric device), after the ram is opened or closed, the two manual devices are clamped again, and the pipeline can work.

We have a blind valve production here.

Blind valves are further divided into electric blind valves, pneumatic blind valves, hydraulic blind valves, open plug-in valves and closed plug-in valves. Open and closed plug valves have been analysed in detail before. The following is a detailed introduction to several blind valves:

1) F943X electric fan-shaped blind valve is a product of automatic fan-shaped blind valve. It is composed of a clamping drive, a flap and a valve body. It is mainly used as a metallurgical valve as a shut-off device in the industrial and mining industry.

This valve can be controlled remotely by a single unit, or by multiple remotes, or manually operated under special circumstances. It is composed of a base and a support column, which has the characteristics of high stability; The sealing ring is on the valve plate, which has the advantage of high sealing performance.

2) F743X hydraulic sector blind valve is mainly composed of left valve body, right valve body, screw rod, ram, sealing ring, lever, hydraulic cylinder and other parts, and is composed of a rigid structure composed of base and support column section. The valve is provided with clamping, loosening cylinder and flap cylinder, clamping, loosening cylinder through lever and screw rod screw drive left and right valve body to complete loosening, clamping action, flap cylinder drive ram to complete switch action.

3) F643X pneumatic sector blind valve is a kind of automatic sector blind valve, and its driving mode is pneumatic, so it is also called pneumatic sector blind valve. F643X pneumatic sector blind valve has 4 kinds of valves, pneumatic sector blind valve, pneumatic sector blind valve, pneumatic sector blind valve, pneumatic sector blind valve.

4) F643X pneumatic sector blind valve can be controlled automatically and remotely controlled partition equipment. It is composed of a left valve body, a right valve body, a middle valve body, and a connecting screw (three). Rotate the connecting screw with a wrench to make the left and right valve bodies complete the clamping and loosening actions, and use the blind plate on the ram to grasp the seepage and the position change of the through hole plate to achieve the purpose of opening and closing.

This valve has the characteristics of simple structure, light weight, reliable performance and convenient operation. This valve is a short structure series, and the rubber sealing ring is installed on the left and right valve bodies respectively. This valve is widely used in metallurgy, environmental protection and other industries with its superior function.

5) F343CX manual sector blind valve is composed of valve body, turbine rotation mechanism, sector blind plate and so on. Its advantage is that the valve body is fixed on the base, and the structure is stable; There is a blind plate positioning block, which can prevent the blind plate from drifting and avoid the abrasion of the sealing ring; The turbine rotation mechanism can loosen the clamping valve body.

The landlord can go to Tianjin No. 1 standard valve manufacturing **** to see, there is a reference to the standard model. **Electric butterfly Zheng mill valve - pneumatic butterfly valve - electric difference open ball valve - pneumatic ball valve - electric control valve - pneumatic control valve - specializing in the manufacture of pneumatic and electric industrial control valves, is a professional valve enterprise integrating design, development, manufacturing and operation.

The blind valve is composed of the left and right valve balance collapse body, the telescopic mechanism, the fan-shaped valve plate and the electric lifting push rod that drives the valve plate and the electric push rod that clamps and loosens. Blocking the front.

Clamp the motor action, drive the screw rod to rotate counterclockwise, the valve body is loosened in place (indicator light display), drive the motor action, drive the ram to rotate counterclockwise in place, the ram is closed in place (indicator light display), clamp the motor action, drive the screw rod to rotate clockwise, and the valve body is clamped in place (indicator light display) to complete the whole process of the valve from opening to closing.
