Description
Technical field
The utility model relates to hydraulic valve testing machine servicing unit, and a kind of especially welding valve is suppressed fixture.Import and export being connected between hydraulic valve testing machine test interface for welding valve.
Background technology
Most of hydraulic valve testing machines can only complete the detection of flange connecting-type valve in the past, but in real work, often run into the valve of welding class, this valve is directly connected with pipeline by welding in actual applications, because welding valve two ends do not have joint flange, thereby in testing, welding valve is imported and exported cannot directly be connected between hydraulic valve testing machine test interface, so hydraulic valve testing machine cannot directly carry out the detection of welding valve.
For above-mentioned situation, now need to design the transition piece that a kind of solder type valve is connected with hydraulic dynamometer, to solder type valve is detected, overcome existing hydraulic dynamometer and can only detect the defect of flange connecting-type valve.
Summary of the invention
The purpose of this utility model is exactly for overcoming the deficiencies in the prior art, a kind of technical scheme of welding valve bulge test fixture is provided, adopt connection member, the combination of sealing packing piece of flanged type interface, form symmetrical clamp assembly, be connected to welding valve by symmetrical clamp assembly and import and export between hydraulic valve testing machine test interface, thereby make hydraulic dynamometer carry out pressure test to welding valve.
The utility model is to realize by such technical scheme: a kind of welding valve is suppressed fixture, formed by two identical clamp assemblies of structure, it is characterized in that, each clamp assembly comprises connection member and O-ring seal two parts, described connection member is three layers of cylindrical lip structure, the column part of diameter maximum is to test with hydraulic valve testing machine the interface A being connected, the column part of diameter minimum is the interface B being connected with welding valve, interface A and interface B center section are transition body, the axial machining center through hole of connection member, interface A end face is sealing plane, the processing of water wave line is done on sealing plane surface, sealing plane is for being connected with the equipment sealing surface of suppressing, interface B column part is processed with annular groove, hermetic unit comprises O-ring seal, sealing copper gasket, O-ring seal is arranged in annular groove, sealing copper gasket external diameter is identical with transition body external diameter, its center-hole diameter and interface B external diameter are slidably matched, sealing copper gasket is sleeved on interface B external diameter.
The beneficial effects of the utility model are: adopt connection member, the combination of sealing packing piece of flanged type interface, form symmetrical clamp assembly, being connected to welding valve by symmetrical clamp assembly imports and exports between hydraulic valve testing machine test interface, thereby make hydraulic dynamometer carry out pressure test to welding valve, welding valve fixture has solved the problem that welding valve cannot carry out bulge test in the past, increase the detection test capability of valve, opened more wide market.

Embodiment
Understand the utility model for clearer, describe in conjunction with the accompanying drawings and embodiments the utility model in detail:
As shown in Figure 1 to Figure 3, welding valve bulge test fixture, formed by two identical clamp assemblies of structure, each clamp assembly comprises connection member 1 and O-ring seal 2 two parts, described connection member 1 is three layers of cylindrical lip structure, the column part of diameter maximum is to test with hydraulic valve testing machine the interface A11 being connected, the column part of diameter minimum is the interface B12 being connected with welding valve, interface A11 and interface B12 center section are transition body 13, the axial machining center through hole 14 of connection member 1, interface A11 end face is sealing plane 15, the processing of water wave line is done on sealing plane 15 surfaces, sealing plane 15 is for being connected with the equipment sealing surface of suppressing, interface B12 column part is processed with annular groove 16, hermetic unit comprises O-ring seal 2, sealing copper gasket 3, O-ring seal 2 is arranged in annular groove 16, sealing copper gasket 3 external diameters are identical with transition body 13 external diameters, its center pit 31 diameters and interface B12 external diameter are slidably matched, sealing copper gasket 3 is sleeved on interface B12 external diameter.
When use, the interface B12 of two connection members 1 is inserted respectively to the entrance and exit of welding valve 4, by the interface A11 of two connection members 1 connecting fluid pressure valve testing machine test interface respectively, when work, hydraulic valve testing machine is suppressed test interface and is tightened up, and two clamp assemblies and middle valve are clamped, reach sealing property requirement, when test, water enters valve internal from central through hole 14, thereby carries out pressure test.
According to the above description, can realize scheme of the present utility model in conjunction with art technology.
