The use and structural characteristics of the wafer check valve
一、 Using: The didlink check valve is installed in the pipeline system, and its main function is to prevent the medium from flowing back. The check valve is an automatic valve that depends on the pressure of the medium to open and close. Wafer check valve is suitable for various pipelines with n...Read more -
Structure and principle of anti-fouling shut off valve
一、Introduction: With the continuous development of the city, many high-rise buildings have sprung up, and water supply pipelines have become one of the main considerations. When there are many high-rise buildings without water or in normal use, due to the structure of the secondary water supply...Read more -
Electric fluorine lined wafer butterfly valve
一、 Purpose: The electric fluorine-lined wafer butterfly valve is a new type of valve that regulates and intercepts gas and liquid media. In the past, ordinary valves could not deal with strong acid-base corrosive media. The strong corrosiveness of the media would cause certain damages to the va...Read more -
Buried soft sealing gate valve
一、Introduction: Buried soft-sealed gate valve is a special gate valve that can be directly buried in the ground to control the flow of buried pipelines. The main feature of the direct-buried soft-seal gate valve is that the upper and lower moving gate serves as the valve opening and closing par...Read more -
Solution to the problem of series pressure of adjustable pressure reducing valve
1. Based on the working principle of the pressure reducing valve, a pressure relief valve is installed behind it. When the pressure after the pressure reducing valve is higher than P2, the pressure relief valve is opened to relieve the pressure to ensure the normal water supply pressure. 2. Short...Read more -
Causes of string pressure problems in adjustable pressure reducing valves
Due to the rupture of the pipe network at the pipe section after the pressure reducing valve, closing the valve at P1 or overhauling, when the pump station A water pump stops running, the water pressure at the pipe section after the pressure reducing valve after the valve is very low or even empt...Read more -
Main features of V type ball valve
1. It has the advantages of compact structure, small volume, and vertical installation. 2. Excellent adjustment characteristics: The V-shaped ball valve has an inherent flow characteristic of approximately equal percentage and an adjustable ratio of up to 300:1. Therefore, the V-valve can provide...Read more -
V-shaped ball valve Introduction
The V-type ball valve is a hard-sealed, tetrafluoro-sealed regulating ball valve. It adopts a movable valve seat structure loaded by a leaf spring, the valve seat and the ball body will not cause problems such as jamming or separation, and the sealing is reliable and the service life is long. Th...Read more -
Structural characteristics of pneumatic V-type control valve
1. Pneumatic V-type control valve is a right-angle rotation structure. It can be used with a valve positioner to achieve proportional adjustment; V-type spool is most suitable for various adjustment occasions. It has a large rated flow coefficient and a large adjustable ratio. The sealing effect ...Read more -
Introduction of Pneumatic Flange Metal Hard Seal Butterfly Valve
The pneumatic flange type metal hard seal butterfly valve is composed of a quarter-stroke pneumatic piston actuator and a three-eccentric butterfly valve body. It is designed with a three-dimensional eccentric principle to make the space movement trajectory of the sealing surface idealized, and t...Read more -
Structural characteristics of liquefied natural gas safety valve
Liquefied natural gas safety valve refers to the low-temperature LNG liquefied natural gas system. The opening and closing parts are normally closed under the action of external force. When the pressure of the low-temperature LNG liquefied natural gas medium in the low-temperature equipment or pi...Read more -
Comparison of electric wafer ball valve and pneumatic wafer ball valve
The electric wafer ball valve is composed of DSR electric actuator and ultra-thin ball valve. Compared with ordinary electric ball valve, the electric ultra-thin ball valve (electric wafer ball valve) has compact structure, small volume, light weight, and the distance between the valve seat and t...Read more
