Description
Technical field
The present invention relates to a kind of mechanically-sealing apparatus, particularly relate to a kind of value pressure test seal disc.
Background technology
In the enterprise having, the valve specifications and models of production and application have a variety of, if valve goes wrong, then need valve is placed under repair, also need value pressure test after repairing, for treating pressure testing valve after repairing, it is necessary to prepare the valve flanges asbestos board gasket seal of the corresponding valve flanges dish of all size, all size, various valves need to use high-strength bolt Flange joint, and valve carries out pressure testing again through stamper after being connected by flange seal.The material that so operation expends is many, and troublesome poeration, labor intensity is also big.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, value pressure test seal disc easy to use.
For achieving the above object, the technical solution used in the present invention is:
A kind of value pressure test seal disc, including stamper, offer stamper through hole in the middle of stamper, it is characterized in that, the upper disk surface of stamper offers multiple concentrically ringed stamper seal groove each other with stamper through hole for center of circle concave downward, in stamper seal groove, is provided with " O " type sealing rubber ring.
A kind of value pressure test seal disc, including above-mentioned stamper, it is characterized in that, airtight above described stamper it is connected to public dish, public dish through hole is offered in the middle of public dish, the upper disk surface of public dish offers public dish seal groove with public dish through hole for center of circle concave downward, in public dish seal groove, also is provided with described " O " type sealing rubber ring；The upper disk surface edge concave downward of public dish offers the valve catching groove corresponding with seam valve.
According to described value pressure test seal disc, it is characterized in that, described stamper upper disk surface center concave downward offers stamper central recess, the stamper surface concave downward at stamper central recess place offers described stamper seal groove, described " O " type sealing rubber ring it also is provided with in this stamper seal groove, under described public dish, card center is downwardly projected and is extended with the public dish convex corresponding with stamper central recess, and public dish convex is airtight snaps onto in stamper central recess.
The present invention includes matching used public stamper and special public dish, rely on " O " the type sealing rubber ring being arranged on stamper and public dish to effective sealing function of liquid medium to meet the valve requirement to pressure test pressure of different size, without consuming too much material, undertaken leakage test is installed by simple and efficient mode, easy to use, effective.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
A kind of value pressure test seal disc, as shown in Figures 1 to 6, including stamper 1, in the middle of stamper 1, stamper through hole 3 is offered, the upper disk surface of stamper 1 offers multiple concentrically ringed stamper seal groove 2 each other with stamper through hole 3 for center of circle concave downward, in stamper seal groove 2, is provided with " O " type sealing rubber ring 10.Described stamper 1 is airtight above is connected to public dish 5, offers public dish through hole 6, the upper disk surface of public dish 5 offers public dish seal groove 7 with public dish through hole 6 for center of circle concave downward, also be provided with described " O " type sealing rubber ring 10 in public dish seal groove 7 in the middle of public dish 5)；The upper disk surface edge concave downward of public dish 5 offers the valve catching groove 8 corresponding with seam valve.Described stamper 1 upper disk surface center concave downward offers stamper central recess 4, the stamper 1 surface concave downward at stamper central recess 4 place offers described stamper seal groove 2, described " O " type sealing rubber ring 10 it also is provided with in this stamper seal groove 2, described public 5 times card centers of dish are downwardly projected and are extended with the public dish convex 9 corresponding with stamper central recess 4, and public dish convex 9 is airtight snaps onto in stamper central recess 4.
The present invention includes public dish and two parts of stamper, stamper is with regard to one, by the pressure testing of the flat mouth valve that " O " the type sealing rubber ring changed in card in different-diameter seal groove is suitable in nominal diameter DN200, public dish is taken off during pressure testing, the medium entrance side faying face of flat mouth valve is correctly placed on stamper, transmission nut on rotary stand, to treat that examination valve is pressed on stamper by piston shoes, by the test medium that " O " type sealing rubber ring sealed lower portion interface enters, reach the effect that pressure testing seals.Such as pressure testing seam valve, then after laying the public dish (including 8 kinds of specifications in the present invention) of all size on stamper, sealed by the compacting of valve seam sealing surface with " O " the type sealing rubber ring on public dish and carry out pressure testing.
For value pressure test, traditional way is after valve repair, and valve connects pressure testing by high-strength bolt flange seal asbestos pad, and labor intensity is big, the material expended is many, waste time and energy, in order to reduce labor intensity, save material cost, this value pressure test seal disc of trial production, this seal disc divides male and female two dishes, and stamper is applied widely
Public dish is small and exquisite, lightweight, flexible for installation, seal disc relies on " O " the type sealing rubber ring between faying face to seal, good sealing effect, proof pressure is high, reusable, by suppressing the use on platform in self-control, safely, flexible, efficiency increases substantially, and reduces material consumption, considerably reduces the labor intensity of workman.
The present invention is that high-efficient light suppresses accessory, can improve and suppress efficiency, ensures the timely pressure testing inspection of the valve after repairing.
Existing liquid one bulge test platform of plunger stamper processing and fabricating can be utilized, the bulge test of latus rectum flat mouth valve between ￠ 10-￠ 200 it is suitable for after " O " type sealing rubber ring being installed in stamper seal groove, when pressure testing seam valve, the public dish of suit again on stamper, as long as 8 public dishes just can meet the bulge test of latus rectum recess valve between ￠ 10-￠ 200.
