Abstract
The invention discloses a preparing craft of antifouling drainer with non-return device, which comprises the following steps: providing a non-returning device on the outlet end valve lid; getting the product. This invention possesses reasonable craft, good idea and simple structure, which can be spreaded widely.
Description
Technical field
The present invention relates to technical field of valve manufacturing, specifically, relate to a kind of manufacturing process of drainage means of valve.
Background technique
Present hydathode is only responded to the pressure of entrance point and intermediate cavity.Its defective is: when main valve leaks when serious, before discharging the main valve leaking medium, an induction process need be arranged, thereby easily cause main valve intermediate cavity pressure greater than entrance point pressure may, the antifouling interrupting performance of main valve was lost efficacy, drainage capacity is less simultaneously.For this reason, the inventor has designed the anti-soil draining equipment of two barrier film totally separating types, but this anti-soil draining equipment and throttle non-return valve can not play antifouling every the stream effect when connecting and composing the single-stage counterflow unit.
Summary of the invention
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, when connecting and composing the single-stage counterflow unit, can play antifouling manufacturing process equally every the anti-soil draining equipment that has check device that flows effect with throttle non-return valve.
For achieving the above object, the present invention adopts following technological scheme: a kind of manufacturing process that has the anti-soil draining equipment of check device mainly comprises following steps: a check device is provided on the outlet end valve gap.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: technology of the present invention is reasonable, be skillfully constructed, the anti-soil draining equipment that has check device that produces, can play the outer control of blocking-up medium loop, i.e. the effect of medium channel from outlet end to the entrance point direction, thereby when connecting and composing the single-stage counterflow unit with throttle non-return valve, can play equally antifouling every stream effect, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is the structural representation that has check device that the present invention produces.
Embodiment
A kind of manufacturing process that has the anti-soil draining equipment of check device mainly comprises following steps: a check device is provided on the outlet end valve gap.Below in conjunction with accompanying drawing the structure that has check device that the present invention produces is described in further detail.Referring to accompanying drawing, a kind of anti-soil draining equipment that has check device, hydathode valve body 3 and outlet end valve gap 1, entrance point valve gap 6 is connected and fixed by being connected and fixed bolt 7, be provided with outlet end diaphragm 2 between outlet end valve gap 1 and the hydathode valve body 3, be provided with entrance point diaphragm 5 between entrance point valve gap 6 and the hydathode 3, be provided with outlet induction valve shaft 9 and import induction valve shaft 8 between outlet end diaphragm 2 and the entrance point diaphragm 5, be provided with caulking gum 4 between the two induction valve shafts, caulking gum 4 forms sealing pair with the hydathode valve body, hydathode valve body 3 nearly entrance point diaphragms 5 places offer equalizing orifice 14, wherein offer outlet pressure induction mouth 10 on the outlet end valve gap 1, offer inlet pressure induction mouth 11 on the entrance point valve gap 6, offer intermediate cavity interface 12 on the hydathode valve body 3, the hydathode valve body offers drain opening 13 3 times, is provided with seal ring 15 between hydathode valve body 3 and the import induction valve shaft 8.Wherein, outlet end valve gap 1 is provided with check device 16.This device can play the outer control of blocking-up medium loop, the i.e. effect of the medium channel from outlet end to the entrance point direction.During use, hydathode inlet pressure induction mouth is connected with the inlet tube of main valve, outlet pressure induction mouth is connected with the outer pipe of main valve, and the intermediate cavity interface is connected with the middle lumen of main valve.When the main valve inlet pressure greater than outlet pressure, main valve is opened, and the power of responding on the entrance point diaphragm makes import induction valve shaft, outlet induction valve shaft, caulking gum contact with the sealing surface of hydathode valve body greater than the power of responding on the outlet end diaphragm, form sealing, hydathode reliably cuts out.When the outlet pressure of main valve greater than, when equaling inlet pressure, main valve is closed, the pressure of responding on the outlet end diaphragm is greater than the pressure of responding on the entrance point diaphragm, by outlet induction valve shaft, import induction valve shaft caulking gum is separated with sealing surface on the hydathode valve body, hydathode is opened, the pressure that makes the main valve intermediate cavity is zero, once producing, any Sealing of main valve leaks, leak medium all from hydathode intermediate cavity interface by flowing to drain opening between hydathode valve body and the caulking gum, row is outside, thereby avoids main valve entrance point medium contaminated.
