Vacuum check valve, also known as vacuum blocking valve, vacuum check valve, vacuum one-way valve, etc., is installed at the suction port of the vacuum pump to prevent the working fluid and air of the vacuum pump from flowing back to the vacuum system in case of pump shutdown or unexpected power outage, which may cause contamination of the working 1
Overview of forged steel globe valves: There are three types of valve cover designs for forged steel stop valves. One is a bolt type valve cover, connected by a concave convex surface, using stainless steel strips and flexible graphite wound gaskets. Ring connections can also be used according to requirements. The second type is a welded valve cove1
Vacuum butterfly valve refers to a butterfly valve that forms a certain vacuum when the working pressure is lower than the standard atmospheric pressure. Applicable vacuum range: 0.6 * 10 ^ 6~1.3 * 10pa ^ -4. The valve is a straight through type, sealed by a butterfly plate, so it can be used in both vacuum and low-pressure conditions, and can be i1
Electric fluorine lined ball valves are mainly used in pipelines with various concentrations of strong alkaline organic solvents and other corrosive gases and liquid media. And it is suitable for conveying various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and various organic acids, strong acids, and strong o1
The all-weather breathing valve is installed on the top of the storage tank to solve the problem of positive and negative pressure gas inside the tank, so that the liquid in and out of the tank is not obstructed. When the external liquid enters the tank, a large amount of gas is exhaled (called positive pressure). When the liquid inside the tank is1
Unique structure, flexible design, lightweight, labor-saving, and quick opening and closing. Expansion butterfly valves not only have the function of compensating for thermal expansion and contraction caused by pipeline temperature difference contraction, but also provide convenience for valve installation and replacement during maintenance. The se1
Pipeline through sight glass is one of the main accessories on industrial pipeline devices. In industrial production devices such as petroleum, chemical, pharmaceutical, and food, the sight glass can observe the flow and reaction of liquids, gases, vapors, and other media in the pipeline at any time, playing a role in monitoring production and avoi1
The WJ41H and WJ41Y steam bellows globe valves, also known as bellows sealed globe valves, are designed with automatic roll welding to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem.
The safety door silencer is a universal mechanical equipment with a wide range of applications. The production of various industries such as power, mining, machinery, metallurgy, and chemical industry cannot be separated from fans. The noise generated by fans during operation often becomes a source of harm to worker health and the environment. Espe1
