Abstract

The utility model discloses a ultra-high-pressure self-sealing pressure-test stop plate component, which comprises a stop plate main body with the center being provided with a pressure test medium through hole, wherein, a piston ring is arranged at the contact part between the front end of the stop plate and a test valve body; the periphery of the stop plate is provided with a stage structure; a V-shaped sealing ring is arranged between the stage and the corresponding piston ring; a compression spring that is installed on a spring seat is arranged at the outer side of the piston ring in a compression way; the spring seat is fixedly connected with the stop plate main body; the part, which is contacted with the stop plate main body, of the piston ring is provided with two O-shaped obturating rings; the part, which is contacted with a test valve body, of the piston ring is provided with two O-shaped obturating rings. The component has reasonable structure; since the piston ring is provided with the inner O-shaped obturating ring and the outer O-shaped obturating ring, the component has good sealability; an additional V-shaped sealing ring further improves the sealing effect, and the V-shaped sealing ring is compressed through a spring, so that even when the O-shaped sealing ring loses effectiveness, the seal can be still ensured.

Description

Novel ultrahigh pressure self sealss PRESSURE TESTING BLIND FLANGE assembly
Technical field:
The utility model relates to a kind of PRESSURE TESTING BLIND FLANGE assembly of testing the valve body sealing property.
Background technology:
The blind plate of existing test valve body sealing property only has single O-ring seal, and test result often can not accurately reflect the sealing property of valve body.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the novel ultrahigh pressure self sealss PRESSURE TESTING BLIND FLANGE assembly of favorable working performance.
Technical solution of the present utility model is:
Novel ultrahigh pressure self sealss PRESSURE TESTING BLIND FLANGE assembly, it is characterized in that: comprise that central authorities are provided with the blind plate body of test medium through hole, blind plate body front end is set with piston ring with test valve body contact site, blind plate body periphery is provided with ledge structure, between step and relative piston ring, be provided with V-shaped seal ring, be pressed with the holddown spring that is loaded on the spring base in the piston ring outside, spring base is fixedlyed connected with the blind plate body, piston ring and blind plate body contact site are provided with two road O RunddichtringOs, and piston ring is provided with two road O RunddichtringOs with test valve body contact site.
The utility model is rational in infrastructure, and piston ring has inside and outside O RunddichtringO, good seal performance; The V-shaped seal ring of setting up has further been strengthened sealing effectiveness, and even V-shaped seal ring when the O RunddichtringO lost efficacy, still can guarantee sealing by spring compression.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
