Technical Field
The utility model relates to the field of valve testing auxiliary tools, in particular to a heat-preservation jacket valve pressure test quick-change chuck.
Background
The heat preservation jacket valve is characterized in that a layer of closed water inlet cavity (jacket) is welded outside the valve body by a thin steel plate so as to cool the valve body by water. The valve is subjected to a shell strength test, a hydraulic sealing test and a pneumatic sealing test before leaving the factory, and the tests are carried out on a semi-automatic pressure testing machine, so that the clamping is convenient. In addition, the weld tightness of the heat-insulating jacket was tested. The flange with the same specification as the jacket water inlet flange is made in the past, and is clamped by bolts and nuts, so that the flange can only be operated manually and is very troublesome.

The utility model adopts the technical scheme that: the heat preservation jacket valve pressure test quick-change chuck comprises a valve water inlet flange plate, a connecting pipe, a nut sleeve and a pull rod sleeve, wherein the pull rod sleeve is movably sleeved on the outer circumference of the connecting pipe, a limiting part which is in limiting fit with the valve water inlet flange plate is arranged on the inner wall of the nut sleeve, and the pull rod sleeve is provided with two actions for driving the connecting pipe to approach and separate from the valve water inlet flange plate.
And a sealing ring is arranged between the connecting pipe and the valve water inlet flange plate.
The limiting piece adopts a split ring baffle, and an annular groove for installing the limiting piece is formed in the inner wall of the nut sleeve.
The handle is arranged on the outer circumference of the pull rod sleeve.
The connecting rod is provided with a first annular step corresponding to the front end position of the pull rod sleeve and a second annular step corresponding to the rear end position of the pull rod sleeve.
And the tail end of the connecting pipe is connected with a rubber hose.
The nut sleeve is in threaded fit with the pull rod sleeve.
The beneficial effects of the utility model are as follows: according to the technical scheme, the valve water inlet flange plate is inserted into the nut sleeve, the limiting piece is installed on the inner wall of the nut sleeve to limit the valve water inlet flange plate, the connecting pipe is driven by the pull rod sleeve to align and communicate with the valve water inlet flange plate, the tightness test of the heat preservation jacket can be carried out, and after the test is finished, the communication can be released by disassembling the limiting piece.
Drawings
