Problems solved by technology
[0003] The rubber elastic body in the butterfly valve body will tear, wear, age, perforate and even fall off. Repairs require special equipment, which consumes a lot of heat and electricity and takes time and effort. Butterfly valves generally have the disadvantage of poor sealing. The metal casting of the valve seat has a relatively simple seal, which will cause wear and tear and affect the sealing performance over time. Therefore, according to the shortcomings of the existing technology, it is necessary to design a high-performance stainless steel butterfly valve valve box casting.

Description
technical field [0001] The invention relates to the field of butterfly valves, in particular to a high-performance stainless steel butterfly valve valve box casting. Background technique [0002] Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure, which can be used for on-off control of low-pressure pipeline medium. It mainly plays the role of cutting off and throttling. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjustment. [0003] The rubber elastomer in the valve body of the butterfly valve will cause tearing, abrasion, aging, perforation and even falling off. Special equipment is required for repair, which consumes a lot of heat and electric energy, which is time-consuming and laborious. But butterfly valves generally have the disadvantage of poor sealing performance. The seali...
