Abstract
The utility model is related to a kind of double-gate plate valve one-way sealing bindiny mechanisms, flap including valve seat and in valve seat, the flap includes import flap and outlet flap, spring is installed between import flap and outlet flap, stepped unthreaded hole is equipped on import flap, threaded hole is equipped on the outlet flap opposite with stepped unthreaded hole of position, one screw, which is mounted on through stepped unthreaded hole in matched threaded hole, is connected import flap with outlet flap, is equipped in spring and blocks in screw head.It can prevent flap from departing from clamping ring pilot hole, flap is avoided to be flicked by spring and flap is caused to come off from clamping ring bring damage, reduce disassembly process, reduce assembly difficulty, the frictionally damage of flap and sealing surface of seat in reduction assembling process.
Description
Technical field
The utility model is related to a kind of double-gate plate valve one-way sealing bindiny mechanisms, belong to valve technology field.
Background technology
Double-gate plate valve when mounted between assembly tool compresses flap spring or using by the way of screw in compression spring into
Row installation, both traditional compressions and mounting means, assembly tool is required to dismantle after flap enters seating position, dress
With complexity, generate frictionally damage between flap and valve seat during assembling, after assembly tool of dismantling can not limited spring free state when
The position of flap be easy to cause damage caused by flap comes off in spring free state from clamping ring.
Utility model content
For above-mentioned deficiency, the utility model provides a kind of double-gate plate valve one-way sealing bindiny mechanism, increases screw
/V is carried out to flap and spring, increases card in spring and /V is carried out to screw, can prevent flap from departing from clamping ring pilot hole, solution
It has determined problems of the prior art.
Used technical solution is the utility model to solve above-mentioned technical problem：
A kind of double-gate plate valve one-way sealing bindiny mechanism, the flap including valve seat and in valve seat, the flap
Including import flap and outlet flap, spring is installed between import flap and outlet flap, ladder is equipped on import flap
Shape unthreaded hole, is equipped with threaded hole on the outlet flap opposite with stepped unthreaded hole of position, and a screw is installed through stepped unthreaded hole
Import flap with outlet flap is connected in matched threaded hole, is equipped in spring and blocks in screw head.
The usefulness of the invention is, reasonable in design, can prevent flap from departing from clamping ring pilot hole, avoid flap quilt
Spring, which flicks, to be caused flap to come off from clamping ring to bring damage, reduces disassembly process, reduces assembly difficulty, reduces assembling process
The frictionally damage of middle flap and sealing surface of seat.

Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with new.
As shown in Figs 1-4：A kind of double-gate plate valve one-way sealing bindiny mechanism, including valve seat 1 and in valve seat
Flap, the flap include import flap 2 and outlet flap 3, and spring 4 is installed between import flap 2 and outlet flap 3,
Import flap 2 is equipped with stepped unthreaded hole 301, and threaded hole is equipped on the outlet flap 3 opposite with stepped unthreaded hole 301 of position
201, a screw 7 is mounted in matched threaded hole 201 through stepped unthreaded hole 301 by import flap 2 and outlet flap 3
It is connected, is equipped on 7 head of screw in spring and blocks 6.
During installation, spring 4 is placed into import flap 2 makes two valves with exporting the designated position in flap 3, pre-compressed spring 4
The distance between valve and 1 contact surface of valve seat are less than the distance between valve seat 1, screw 7 are installed to through unthreaded hole 301 matched
Threaded hole 201 in, tighten screw 7, card in spring 6 be installed in inner card cage 302, by the import flap 2 combined with going out
Mouth flap 3 is installed between valve seat 1, unclamps screw 7 with allen wrench, until blocking 6 end faces in spring, head of screw can be in ladder
It axially moves in shape unthreaded hole 301；During dismounting, screw 7 is tightened, is less than the distance between two flaps and 1 contact surface of valve seat
The distance between valve seat 1 takes out the import flap 2 combined and outlet flap 3 from valve seat.
For the ordinary skill in the art, introduction according to the present invention, do not depart from the principle of the present invention with
In the case of spirit, the changes, modifications, replacement and the modification that are carried out to embodiment still fall within protection scope of the present invention it
It is interior.
