Abstract

Plastic valve. The valve includes a main body in which a fluid transfer hole through which a fluid moves is formed in an inner space; and an opening / closing portion that opens and closes a hole formedin the main body, the opening / closing portion having a stepped shape, a portion of the opening / closing portion blocking the hole when the valve is closed, and a portion of the opening / closing portionhaving the stepped shape being capable of rising upward when the valve is opened.

Description

technical field [0001] The present invention relates to plastic valves. Background technique [0002] A valve is a mechanism that can open and close the flow of fluid, and uses a diaphragm or a ball to control the flow of fluid. [0003] figure 1 It is a schematic diagram showing the structure of a general valve. [0004] see figure 1 , the valve includes a body 100 , a diaphragm 102 and an operating part 104 for controlling the diaphragm 102 . [0005] A fluid transfer hole 106 is formed inside the body 100 , and the fluid input from the input end 110 of the fluid transfer hole 106 is discharged through the output end 112 . [0006] Conventional valves used in semiconductor manufacturing processes and the like have a problem that the fluid, which is a highly toxic chemical substance, remains inside the main body, causing frequent damage to the main body. In the case of transferring a fluid that is a highly toxic chemical substance, it is necessary to minimize the amoun...
