Z45X Soft seal gate valve

Detailed Introduction of Soft Sealing Gate Valve Basic Concept of Soft Sealing Gate Valve soft sealing gate valve is a type of valve widely used in pipeline systems, mainly used to control the flow of liquids or gases. It is divided into two types: exposed stem soft sealing gate valve and the concealed stem soft sealing gate valve. It usually has trapezoidal threads on the lifting stem, which, through the nut the middle of the gate plate and the guide groove on the valve body, converts the rotary motion into linear motion, thus converting the operating torque into operating thrust. Working When opening the valve, when the gate plate is lifted to a height equal to 1:1 times the valve bore, the fluid passage is completely unobed. However, in actual use, the valve is usually marked with the top of the valve stem as the full open position, that is, the position where it be opened any further. Therefore, the full open position of the valve is determined according to the position of the gate plate (i.e., the stroke). Installation RequirementsThe soft sealing gate valve should generally be installed horizontally in the pipeline. Its specifications and categories should meet the requirements of the pipeline design documents, the working pressure should be the working pressure of the pipeline, and the valve can withstand a working pressure greater than the actual working pressure of the pipeline without affecting the price. The soft sealing gate should be able to withstand 1.1 times the valve working pressure value without leakage on either side when closed; when the valve is open, the valve body should able to withstand twice the valve working pressure requirements. Features of Soft Sealing Gate Valve Flat Bottom Valve Seat Design The existing gate valve, even if the valve, valve cover, and various parts are all intact, can no longer be used if the sealing surface is slightly deformed or corroded. Therefore, the gate valve the using unit hopes for is that the valve seat and valve plate sealing surface are not easy to deform, corrosion-resistant, and the easily damaged sealing material can be replaced The valve plate should not have friction with the sealing surface when opening and closing, or the friction should be reduced as much as possible, so as to avoid various shortcomings the soft sealing gate valve. Double Parallel Gate Plate Valve Structure The soft sealing gate valve adopts a double parallel gate plate valve structure, and the inlet sealing mode is the inlet valve plate is composed of a sealing sleeve and a force-relieving valve plate as the main sealing gate plate. The sealing sleeve and the force-relieving valve move synchronously but are not connected. The pipeline pressure is transmitted to the valve seat on the outlet surface through the force-relieving valve plate and the leveling force, which greatly improves the combining force of the soft sealing surface. Corrosion-resistant Rubber Sealing Sleeve The valve plate is covered with a corrosion-resistant rubber sealing, which isolates the liquid transported in the pipeline from the parts inside the valve core, avoiding corrosion and blockage by impurities. The replacement of the sealing material this valve is very convenient, so the service life is more than 5 times that of ordinary gate valves. Application Scope of Soft Sealing Gate Valve The soft gate valve is widely used in high-pressure, high-temperature, and corrosive media pipelines in the petroleum, chemical, electric power, metallurgy, light industry, food industries, and is used as an opening and closing device. Special Type of Soft Sealing Gate Valve – Encrypted Soft Sealing Gate Valve Product Overview encrypted soft sealing gate valve is the latest high-tech product developed in China. It uses special components and is encoded by computer based on probability. This valve has the characteristics good anti-theft performance (three insurances), easy opening and closing, and good sealing effect. Working Principle The working principle of the encrypted soft sealing gate valve to control and protect the valve opening and closing through special components and magnetic pole coding technology. This design can effectively prevent excessive water use, refusal to pay water fees, other behaviors, and protect the pipeline water from theft and illegal use. Application.
