Model utility content
Single, different in order to overcome the micro-water test splice of SF6 equipment apparatus function, can not meet the problem that pressure shows demand, the utility model provides the micro-water test of a kind of SF6 equipment special joint, realize the versatility of the micro-water test splice of SF6 equipment, and can show gas pressure, increase work efficiency.
The utility model is to solve the problems of the technologies described above the technological scheme adopting to be:
The micro-water test of a kind of SF6 equipment special joint, for four-way valve form, comprise pressure display end, test instrument hose connection end, check valve end, equipment connection port end, the inside of described micro-water test special joint has a chamber, the top of described chamber is fixedly connected with pressure display end, bottom thread connects check valve end, a side connecting test instrument hose connection end in the left and right sides, opposite side connection device connecting port end in the left and right sides, pressure display end is relative with check valve end, and test instrument hose connection end is relative with equipment connection port end.
Further, described pressure display end is a pressure gauge.
Further, described test instrument hose connection end be the stepped pipe of tool form fill in crush seal interface, pipe one end that diameter is large connects described chamber, the other end connects one end of the pipe that a diameter is little, the other end of the pipe that diameter is little connects the flexible pipe of micro-water testing instrument, and the port of the other end of the pipe that diameter is little arranges the joint plastics mouth that an elasticity is large, and the diameter of the flexible pipe of the diameter of the pipe that diameter is little and micro-water testing instrument matches.
Further, described check valve end is a needle-valve, is threaded with described chamber, and the head of check valve end stretches into the inside of described chamber.
Further, described equipment connection port end is for having an extension tube and an internal thread tube head, described extension tube one end is connected with described chamber, the other end is connected with internal thread tube head, one sealing gasket is set in internal thread tube head, internal thread tube head can independent rotation, and internal thread tube head can coordinate with the tube head of SF6 equipment.
The beneficial effects of the utility model are, show in real time the force value of SF6 equipment by pressure display end, utilize equipment connection port end to make with the attended operation of SF6 equipment simple and convenient, in the time of fault, can close rapidly check valve end, prevent that gas leakage from waiting the generation of harm.The utility model reasonable in design, design typification is unified, simple to operation, is conducive to the enforcement of standardization job on-the-spot.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the micro-water test of SF6 equipment of the present utility model special joint.
In figure, each component names is as follows:
A-pressure display end, B-test instrument hose connection end, C-check valve end, D-equipment connection port end
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, the micro-water test of SF6 equipment of the present utility model special joint, for four-way valve form, comprise four functional areas: pressure display end A, test instrument hose connection end B, check valve end C, equipment connection port end D, the inside of described micro-water test special joint has a chamber, the top of described chamber is fixedly connected with pressure display end A, bottom thread connects check valve end C, a side connecting test instrument hose connection end B in the left and right sides, opposite side connection device connecting port end D in the left and right sides, pressure display end A is relative with check valve end C, test instrument hose connection end B is relative with equipment connection port end D.
Pressure display end A is a pressure gauge, can show in real time the force value of SF6 equipment.
Test instrument hose connection end B be the stepped pipe of tool form fill in crush seal interface, pipe one end that diameter is large connects described chamber, the other end connects one end of the pipe that a diameter is little, the other end of the pipe that diameter is little connects the flexible pipe of micro-water testing instrument, and the port of the other end of the pipe that diameter is little arranges the joint plastics mouth that an elasticity is large, and the diameter of the flexible pipe of the diameter of the pipe that diameter is little and micro-water testing instrument matches.When use, firmly press down past joint plastics mouth, the flexible pipe of micro-water testing instrument is filled in the pipe that diameter is little simultaneously, then loosing one's grip can be by solid the flexible pipe crush seal of micro-water testing instrument, and this design operation is easy, good sealing effect.
