Abstract
The utility model discloses a flange gasket. The flange gasket comprises a body, and is characterized in that a through hole is formed in one end of the body, a hole is formed in the outer side of the through hole, and is perpendicularly communicated with the through hole, and the hole is communicated with a test tube arranged on the outer side of the body. When the flange gasket is installed in a pipeline system, testing can be directly carried out under the actual use conditions, and the testing can be rapid, accurate, economical and unified.
Description
Technical field
The utility model relates to a kind of flange gasket, for high pressure pipe line system and common ASME B16.5 pipe-line systems such as API6A or API17D, belongs to the flange gasket technical field.
Background technique
Flange gasket, as a kind of sealing connecting element, is being brought into play vital effect in pipe-line system, and the quality of it and flange contact facings sealing directly affects efficiency and the safety of pipe-line system.Testing fast, accurately, economically the sealability between flange gasket and flange, is the large problem of pendulum in face of the pipe-line system worker.Traditional test method is that flange gasket is connected in the device of a sealing, by adding hydraulic pressure (high pressure) or air pressure, detects the sealing between flange gasket and flange.Its shortcoming is that installation cost is high; Uneconomical; High pressure generally will be used hydraulic pressure, and air pressure is dangerous; Homogeneity is poor, during test, do not leak, and environment difference during due to use, the installation conditions difference, be not equal to while using and also do not leak.
Summary of the invention
To be solved in the utility model is that existing flange gasket cost is high, dangerous under air pressure, the technical problem that homogeneity is poor.
In order to address the above problem, the utility model provides a kind of flange gasket, comprises body, it is characterized in that, an end of body is provided with through hole, and the outside of through hole is provided with hole, through hole and hole vertical connection, and hole is communicated with the testing tube in the body outside.
Two of through hole communicates with flange sealing trough, and testing tube exposes from the flange outside.
The utility model is arranged in pipe-line system, can under actual service conditions, directly be tested, and makes test quick, accurate, economical, same.
Compared with prior art, the utility model has the advantage of:
1, this flange gasket construction is simple, easy to make, as long as bore one group of T-shaped hole, the pipe of burn-oning on the annular flange pad;
2, can directly burn-on under the pipeline use state joint of different size carries out leakage test, cut off weld bond after test and get final product, test fast, accurately, economical, same.
The accompanying drawing explanation
The structural representation of a kind of flange gasket that Fig. 1 provides for the utility model;
Fig. 2 is the schematic diagram of flange gasket when leak-testing.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1, the structural representation of a kind of flange gasket provided for the utility model, comprise annular shim body 1, a side in shim body 1 is opened the tee T hole, first open a vertical through hole 2, then open a horizontal hole 3 in the outside of through hole 2, this hole 3 leads to flange facing, vertical with through hole 2, finally on hole 3, weld a testing tube 4.
When test flange gasket and flange facing leakage situation, can be in actual using area test, as shown in Figure 2, the flange gasket that the utility model is provided is arranged in flange, the two ends of through hole 2 communicate with flange sealing trough, testing tube 4 extends to the flange outside, one end of testing apparatus gas joint 5 is welded on testing tube 4, according to test request, is inflated to certain pressure, turn off the test chamber source of the gas, the pressurize certain hour, contrast bleed pressure and test chamber pressures, as decline of pressure overflows, sealing face leakage is described, otherwise leak-down rate meets the requirements.Be completed, prescind the testing tube weld bond, make pipe range loss minimum.
