Abstract

The utility model discloses a suppress frock, including suppressing the joint, suppress and connect including the cecum, the cecum is provided with a recess, and the pipe fitting includes to be imported and the export, the export of pipe fitting is stretched into the recess, its characterized in that, suppress and seted up the exhaust hole on the joint, the exhaust hole with the recess link up the installation discharge valve of exhaust hole department connects on connecting, installs discharge valve. The utility model discloses a suppress frock can be with the gaseous emptying in the pipe fitting when suppressing to ensure the accuracy of hydraulic pressure test data.

Description

Suppress frock
Technical field
The utility model relates to one and suppresses frock, be specifically related to a kind of can easy to exhaust suppress frock.
Background technology
Pipe fitting for conveying high-pressure liquid, gas needs to carry out withstand voltage test by root, and withstand voltage test is qualified just can dispatch from the factory. In conventional art, first the end being contained in pipe fitting to be tested will be blocked during withstand voltage test, then hold out against with screw block, the high pressure in high pressure water access tube part is born by screw block, the most backward water filling mouth blocked leads to into pressure height to the high pressure water of 15-20MPa, pressurize certain time, remove test fixture, suppress test and complete.
In prior art, suppressing frock and comprise and suppress joint, suppress joint and comprise cecum, cecum is provided with a groove, and pipe fitting comprises import and outlet, and groove is stretched in the outlet of pipe fitting. Before suppressing, pipe fitting with suppressing frock cecum mutually fix. When suppressing, the gas in pipe fitting cannot emptying, due to the compressibility of gas, affect the accuracy of hydro-test data.
Practical novel content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide one to suppress frock, suppresses, to solve, the technical problem that frock is difficult to easy to exhaust in prior art.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Suppress frock, comprise and suppress joint, described joint of suppressing comprises cecum, and described cecum is provided with a groove, and pipe fitting comprises import and outlet, described groove is stretched in the outlet of described pipe fitting, it is characterized in that, described in suppress joint offered venting hole, described venting hole and described groove are through, vent valve joint is installed at described venting hole place, vent valve installed by described vent valve joint.
Aforesaid suppress frock, it is characterised in that, described groove comprises bottom portion of groove, and described venting hole one end and described bottom portion of groove are through, and the described venting hole the other end installs vent valve joint.
Aforesaid suppress frock, it is characterised in that, the outlet of pipe fitting with suppressing joint mutually fix.
Aforesaid suppress frock, it is characterised in that, the one end being connected with vent valve joint in described venting hole is upwards arranged.
Usefulness of the present utility model is: one of the present utility model suppresses frock, it is possible to when suppressing by the gas emptying in pipe fitting, so that it is guaranteed that the accuracy of hydro-test data.
Accompanying drawing explanation
Fig. 1 is the structural representation preferably implemented that the utility model suppresses frock.
The implication of Reference numeral in figure:
1, joint is suppressed, 2, cecum, 3, groove, 4, import, 5, outlet, 6, venting hole, 7, vent valve joint, 8, vent valve, 9, bottom portion of groove, 10, pipe fitting.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model done concrete introduction.
With reference to shown in Fig. 1, of the present utility model suppress frock, comprising and suppress joint 1, suppress joint 1 and comprise cecum 2, cecum 2 is provided with a groove 3, pipe fitting 10 comprises import 4 and outlet 5, groove 3 is stretched in the outlet 5 of pipe fitting 10, suppresses and has offered venting hole 6 on joint 1, and venting hole 6 is through with groove 3, vent valve 8 joint 7 is installed at venting hole 6 place, vent valve joint 7 is installed vent valve 8. Owing to former frock cecum 2 of suppressing does not have venting port, when suppressing gas cannot emptying, due to the compressibility of gas, affect the accuracy of hydro-test data. Frock cecum 2 suppressed by pipe fitting 10 increases a venting hole 6, and venting hole 6 must be driveed on top, and for gas emptying, venting port welds a vent valve joint 7, installs a vent valve above joint. Before suppressing, vent valve is opened, and liquid injects from import 4, and air is ejected by liquid from venting port, when venting port expel liquid then illustrates air emptying, closes vent valve, starts pressurization.
As further preferably, groove 3 comprises bottom portion of groove 9, and venting hole 6 one end and bottom portion of groove 9 are through, and venting hole 6 the other end installs vent valve joint 7. The outlet 5 of pipe fitting 10 with suppressing joint 1 mutually fix. The one end being connected with vent valve joint 7 in venting hole 6 is upwards arranged.
One of the present utility model suppresses frock, it is possible to when suppressing by the gas emptying in pipe fitting 10, so that it is guaranteed that the accuracy of hydro-test data.
More than show and describe ultimate principle of the present utility model, main feature and advantage. The technician of the industry is not it should be understood that above-described embodiment limits the utility model in any form, and all employings are equal to the technical scheme that the mode of replacement or equivalent transformation obtains, and all drop in protection domain of the present utility model.
