Abstract
The utility model discloses a kind of quick position and choke stop evacuation valve flap assembly is installed, belong to valve field.This quick position is installed choke stop evacuation valve flap assembly and is comprised flap, valve pocket, valve seat, pressure ring, soft seal circle; Described valve seat upper end circumferential surface has a positioning table downwards, has and lack with the location of valve seat positioning table adaptation bottom valve pocket; The sealing of described flap is arranged in valve pocket, and flap has the equalizing orifice that two are connected valve body upper cavities and lower chamber, uniformly bottom flap is provided with three fixing rods; Described fixing rod one end is provided with elastic card cap; Described pressure ring shape and valve seat adaptation, and have T-shaped hole in upper-end surface, pressure ring inner peripheral surface has the auxiliary hole be communicated with T-shaped hole.Adopt the utility model structure simple, choke stop evacuation valve flap assembly can be installed by quick position.
Description
Technical field
The utility model relates to valve field, and specifically a kind of quick position installs choke stop evacuation valve flap assembly.
Background technique
Choke stop evacuation valve is a kind of double seal valve, plays in the conveyance conduit being mainly used in oil, rock gas, coal gas, blau gas etc., uses usually used as regulable control or cut-out.Such valve is a kind of novel throttling, cut-off, emptying product, has multistage throttle effect, the features such as restriction effect is obvious, sealing is reliable, convenient operating maintenance.
In existing choke stop evacuation valve, valve seat install location need to rely on flap or pressure ring could with valve body three location and installation.So not only trouble is installed, and easily because of when installing pressure ring or flap, because discontinuity causes valve seat to damage when mounted.
Model utility content
The utility model aims to provide a kind of quick position and installs choke stop evacuation valve flap assembly, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of quick position installs choke stop evacuation valve flap assembly, it is characterized in that: described flap assembly comprises flap, valve pocket, valve seat, pressure ring, soft seal circle; Described valve seat upper end circumferential surface has a positioning table downwards, has and lack with the location of valve seat positioning table adaptation bottom valve pocket; The sealing of described flap is arranged in valve pocket, and flap has the equalizing orifice that two are connected valve body upper cavities and lower chamber, uniformly bottom flap is provided with three fixing rods; Described fixing rod one end is provided with elastic card cap; Described pressure ring shape and valve seat adaptation, and have T-shaped hole in upper-end surface, pressure ring inner peripheral surface has the auxiliary hole be communicated with T-shaped hole.
Further, described elastic card cap diameter is greater than T-shaped bore dia.
Further, described valve pocket upper end outer circumferential is provided with outwardly positive stop lug boss.
Further, described valve pocket outer peripheral surface has the annular groove that at least one places sealing O shape circle.
The beneficial effects of the utility model are:
One, on valve seat, have positioning table, adaptive mutually with the location phase shortage bottom valve pocket, by the pressure ring with seat shape establishing, three is mutually tentatively fixing.When valve seat is arranged in valve body, be more prone to.
Two, flap bottom even is provided with three fixing rods, stretches in the T-shaped hole of pressure ring by the elastic card cap of fixing rod one end, when by radial direction, elastic card cap inwardly compresses, and when laterally reaching bottom, elastic card cap expands outwardly, and flap and pressure ring is fixed.Make pressure ring and flap can realize quick position to install.
Three, have the auxiliary hole being communicated with T-shaped hole at pressure ring inner peripheral surface, for pressure elasticity card cap, make card cap can realize dismounting and repeatedly utilize.
Four, be provided with outwardly positive stop lug boss at valve pocket upper end outer circumferential, when mounted, positive stop lug boss directly can effectively stop the firmly excessive valve seat that causes to squeeze bad phenomenon.
Accompanying drawing explanation
Fig. 1 is that the quick position that the utility model provides installs choke stop evacuation valve flap modular construction schematic diagram.
Mark in figure: 1 be valve seat, 2 be positioning table, 3 for location lack, 4 be valve pocket, 5 be annular groove, 6 be equalizing orifice, 7 be pressure ring, 8 be fixing rod, 9 be auxiliary hole, 10 for flap.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of quick position installs choke stop evacuation valve flap assembly, it is characterized in that: described flap assembly comprises flap 10, valve pocket 4, valve seat 1, pressure ring 7, soft seal circle; Described valve seat 1 upper end circumferential surface has a positioning table 2 downwards, has and lack 3 with the location of valve seat positioning table 2 adaptation bottom valve pocket 4; The sealing of described flap 10 is arranged in valve pocket 4, and flap 10 has the equalizing orifice 6 that two are connected valve body upper cavities and lower chamber, uniformly bottom flap 10 is provided with three fixing rods 8; Described fixing rod 8 one end is provided with elastic card cap; Described pressure ring 7 shape and valve seat adaptation, and the T-shaped hole had in upper-end surface, pressure ring 7 inner peripheral surface has the auxiliary hole 9 be communicated with T-shaped hole.Described elastic card cap diameter is greater than T-shaped bore dia.Described valve pocket 4 upper end outer circumferential is provided with outwardly positive stop lug boss.Described valve 4 overlaps outer peripheral surface and has the annular groove 5 that at least one places sealing O shape circle.
When assembling, only fixing rod 8 need be aimed in the T-shaped hole on pressure ring 7, insertion can be installed.Again the positioning table 2 of valve seat 1 is lacked 3 with the location of valve pocket 4 to align, pressure ring 7, valve seat 1 are mutually tentatively fixing with valve pocket 4 three.Adopt the utility model structure simple, choke stop evacuation valve flap assembly can be installed by quick position.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
