1. Compared with the existing pipeline, the high-pressure test pressure gauge seat described in the utility model does not need steel pipe, ferrule tee, terminal ferrule, less supporting tooling, low failure rate, and easy maintenance;

2. A high-pressure pressure test pressure gauge seat described in the utility model only needs to be installed in conjunction with a needle-shaped air release plug and a flat shoulder joint to replace the existing high-pressure test system pipeline. It is simple to install and easy to use. convenient;

3. The structure of a high-pressure test pressure gauge seat described in the utility model is simple, and the factory can use its own lathe for processing, which saves the purchase process and reduces the manufacturing cost;

4. The deflation needle plug can be installed and fixed through the internal thread interface of the gauge base and the gauge base, and the working state of the high pressure test system pipeline can be changed by tightening or loosening. When tightening, the deflation needle plug and the gauge base The high-pressure type pressure test pressure gauge seat is hard-sealed with a tapered surface, which has good airtightness and provides a sealed environment for the pressure test. When it is unscrewed, the high-pressure gas passes through the vent needle plug and the high-pressure type pressure test pressure gauge seat. The gap between them releases high-pressure gas to the outside. the

The above-mentioned watch base joint installation part includes a installation groove. the

The above-mentioned watch base joint installation part also includes a welding joint located between the installation groove and the surface of the watch base body. The pressure gauge is welded on the body of the gauge base through a gauge base joint. the

The above-mentioned meter seat joint installation part is a flat shoulder joint installation part. the

The above-mentioned valve installation part includes an external thread joint. the

The externally threaded joint mentioned above is a G1/2 high pressure ball valve joint. the

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is described in detail:

FIG. 5 is a schematic cross-sectional view of FIG. 3 in a pressure release state. the

Detailed ways:

As shown in Figure 1, the pipelines of the high pressure test system used in the existing hydraulic system pressure test. It needs 2 high-pressure ball valves 1', 1 ferrule tee 2', 2 stainless steel pipes 3', 5 terminal ferrules 4', 1 deflated hose nozzle 5' and other tooling to match the pressure gauge. It has a complex structure, takes a long time and costs a lot to make. the

As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a high-pressure pressure test pressure gauge seat includes a flat shoulder joint installation part 1, a G1/2 high-pressure ball valve joint 2 and a needle-shaped air release plug installation Part 3, G1/2 high-pressure ball valve joint 2 communicates with the deflation needle plug installation part 3 through a main pipe 4, the flat shoulder joint installation part 1 communicates with the main pipe 4 through a primary pipeline 5, and the deflation needle plug installation part 3 includes an internal thread interface 31 for the installation of the deflation needle plug and a sealing surface 32 matched with the deflation needle plug. The flat shoulder joint mounting part 1 includes a mounting groove 11 and a welding surface 12 positioned at the mounting groove 11 and the surface of the watch base body. The G1/2 high-pressure ball valve joint adopts an external threaded joint. the

The flat shoulder joint 6 is plugged and installed through the installation groove 11 on the flat shoulder joint installation part 1, and is welded through the welding surface 12 of the watch base body, and the needle-shaped air release plug 7 is passed through the needle-shaped air release plug installation part 3. The internal thread interface 31 is rotatably installed on the pressure gauge seat, and the working state of the high-pressure test system pipeline can be changed by tightening or loosening. The tapered surface is used for hard sealing, which has good airtightness and provides a sealed environment for pressure testing. When it is unscrewed, high-pressure gas leaks out through the gap between the venting needle plug 7 and the sealing surface 32 of the high-pressure test pressure gauge seat. Release the gas under pressure. the
