Abstract
The utility model discloses a ultra-high-pressure large-diameter self-sealing pressure-test stop plate component, which is characterized in that the component includes a stop plate main body with the center being provided with a stop plate main body, wherein, a piston ring is arranged at the contact part between the front end of the stop plate and a test valve body; an O-shaped obturating ring is arranged on the contact part between the piston ring and the stop plate main body, and an O-shaped obturating ring is arranged on the contact part between the piston ring and a test valve body. 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
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 UHV (ultra-high voltage) heavy caliber self sealss PRESSURE TESTING BLIND FLANGE assembly of favorable working performance.
Technical solution of the present utility model is:
A kind of UHV (ultra-high voltage) heavy caliber 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, piston ring and blind plate body contact site are provided with the O RunddichtringO, and piston ring is provided with the O RunddichtringO with test valve body contact site.
Blind plate body periphery is provided with ledge structure, is provided with V-shaped seal ring between step and relative piston 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.
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.
