Embodiment
[0047] Embodiment: By opening a circular hole 2 on the valve body 1, a first sealing ring groove is opened in the middle of the inner edge of the circular hole 2, and a through hole 7 is provided at the upper end of the circular hole 2, and the through hole 7 is circular and It communicates with the circular hole 2, and a second sealing ring groove 8 is opened in the middle of the inner wall of the through hole 7. The through hole 7 is used to install the rotating handle of the butterfly valve. There are two circular holes 2, and the two circular holes 2 are arranged symmetrically. On both sides of the valve body 1, two circular holes 2 are provided on the same valve body 1 for installing disc valves, which can save space. The arrangement positions of the first sealing ring groove 6 and the second sealing ring groove 8 It is also more reasonable and plays a sealing role after the sealing ring is installed, and the volume of the valve body 1 can be reduced structurally. The pla...

The invention discloses a butterfly valve body structure. The butterfly valve body structure comprises a valve body, circular holes are formed in the valve body, first sealing ring grooves are formedin the middles of the inner side edges of the circular holes, through holes are formed in the upper ends of the circular holes, the through holes are circular and communicate with the circular holes,second sealing ring grooves are formed in the middles of the inner walls of the through holes, mounting holes are further formed in the valve body, third sealing ring grooves are formed in the plane of the valve body and located on the peripheries of the circular holes, the number of the circular holes is two, the two circular holes are formed in the two sides of the valve body symmetrically, theroughness of the edge of the circumferential position of each circular hole is 0.8, the third sealing ring grooves are formed in the plane of the valve body and located in the peripheries of the circular holes so that sealing can be performed through the plane, the valve body is further provided with the mounting holes so that the butterfly valve body structure can be fixed to a required positionthrough the plurality of mounting holes. The butterfly valve body structure has the characteristics of being novel in structure, convenient and practical, and compared with an existing butterfly valvebody process, the machining method is simple.
Description
technical field [0001] The invention relates to the technical field of butterfly valves, in particular to a processing method for a butterfly valve body structure. Background technique [0002] Butterfly valve is a kind of valve which uses disc type opening and closing parts to turn back and forth about 90° to open, close or adjust the flow of medium. Butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, but also has good flow regulation function and closing and sealing characteristics at the same time. One of the fastest valve varieties. Butterfly valves are widely used. The variety and quantity of its use are still expanding, and it is developing towards high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment characteristics, and multi-function of a valve. Its reliability and other performance indicators have reached...
