Understand why trapezoidal valve sealing ring is selected for loose sleeve part of electric ball valve? The electric ball valve is the equipment used to connect the pump, valve and pipeline. It is connected by bolts to form a whole, and then a certain displacement is generated, which is also convenient for our installation and maintenance. The displacement of the electric ball valve is generated by bolt connection to form a whole. The principle of valve compression elastic deformation is adopted inside the electric ball valve to make it simple and convenient in pipeline engineering installation, convenient for valve installation, and able to bear the axial tension of the pipeline. The metal and sealing ring of electric ball valve shall be selected in strict accordance with the use performance and user requirements.
The exterior of the material is coated with high-strength anti-corrosion paint, and the connecting bolts of each part are made of high-strength carbon steel or stainless steel. Because there is a certain gap between the body and the expansion tube, it has a certain axial and radial displacement. It can effectively compensate and relieve the thrust of pipeline and blind plate in the pipeline, and also facilitate the installation, maintenance and replacement of pumps and valves. It is actually the most ideal supporting product in the pipeline installation and operation industry. The electric ball valve produced by Gongyi Hengchang Pipeline Equipment Co., Ltd. is made of metal casting or welding. Trapezoidal valve sealing ring is selected for the loose sleeve part. Under the action of the gland and bolt, the principle of valve compression elastic deformation is used to force the sealing ring to deform between the outer wall of the expansion pipe of the electric ball valve body for static sealing.
