Abstract
The invention discloses a preparing craft of completely abrupt type antifouling drainer, which comprises the following steps: A, providing outlet end film sheet between outlet end valve cover and drainer valve body; B, providing inlet end film sheet between the inlet end valve cover and the drainer; C, providing outlet inductive valve-spindles and inlet inductive valve-spindles between the outlet end film sheet and the inlet end film sheet. This invention possesses reasonable craft and good idea, 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.
Summary of the invention
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, can guarantee the manufacturing process of the totally separating type anti-soil draining equipment of the antifouling interrupting performance of main valve.
For achieving the above object, the present invention adopts following technological scheme: a kind of manufacturing process of totally separating type anti-soil draining equipment mainly comprises following steps: provide the outlet end diaphragm between A. outlet end valve gap and the hydathode valve body; B. provide the entrance point diaphragm between entrance point valve gap and the hydathode; C. provide outlet induction valve shaft and import induction valve shaft between outlet end diaphragm and the entrance point diaphragm; D. provide caulking gum between the two induction valve shafts, caulking gum and hydathode valve body form sealing pair; E. the nearly entrance point diaphragm of hydathode valve body place provides an equalizing orifice; F. wherein provide outlet pressure induction mouth on the outlet end valve gap; G., one inlet pressure induction mouth is provided on the entrance point valve gap, an intermediate cavity interface is provided on the hydathode valve body, a drain opening is provided under the hydathode valve body.
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 hydathode that produces, owing to adopt two diaphragm structures, so can respond to main valve inlet/outlet end pressure simultaneously, all the time be in full-gear, negotiability is bigger, when main valve leaks when serious, because non-inductive process, the medium that is leaked can directly be discharged from drain opening, can not cause the phenomenon of main valve intermediate cavity pressure greater than inlet pressure, thereby guaranteed the antifouling interrupting performance of main valve, had 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 of the totally separating type anti-soil draining equipment made of the present invention.
Embodiment
A kind of manufacturing process of totally separating type anti-soil draining equipment mainly comprises following steps: provide the outlet end diaphragm between A. outlet end valve gap and the hydathode valve body; B. provide the entrance point diaphragm between entrance point valve gap and the hydathode; C. provide outlet induction valve shaft and import induction valve shaft between outlet end diaphragm and the entrance point diaphragm; D. provide caulking gum between the two induction valve shafts, caulking gum and hydathode valve body form sealing pair; E. the nearly entrance point diaphragm of hydathode valve body place provides an equalizing orifice; F. wherein provide outlet pressure induction mouth on the outlet end valve gap; G., one inlet pressure induction mouth is provided on the entrance point valve gap, an intermediate cavity interface is provided on the hydathode valve body, a drain opening is provided under the hydathode valve body.Describe in further detail below in conjunction with the structure of accompanying drawing the totally separating type anti-soil draining equipment of manufacturing of the present invention.Referring to accompanying drawing, a kind of totally separating type anti-soil draining equipment, 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.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.
