Technical field
The present invention relates to gas test special joint device, more particularly to one kind are applied to the micro- water of transformer station's SF6 equipment
Test special joint device.
Background technology
With increasing for transformer station's GIS device, the micro- water test job of SF6 equipment is more and more important, used as its critical component
Joint just become more to project because of the problem that the different design of different manufacturers form brings.The micro- water of SF6 equipment for adopting at present
Test splice finds joint single function during long-term use, different, needs repeatedly splicing etc. to ask in use
Topic, and the GIS device having does not have pressure display end, and existing joint can not meet the demand that pressure shows.Existing SF6 sets
Not only connection procedure is more complicated for standby micro- water test splice, and the time used is longer, and can not show gas pressure, has both affected work
Make efficiency, but it is dangerous.
The content of the invention
In order to overcome the micro- water test splice apparatus function of SF6 equipment single, different, it is impossible to meet pressure and show demand
Problem, the present invention provides a kind of micro- water of SF6 equipment and tests special joint, realizes the versatility of the micro- water test splice of SF6 equipment,
And gas pressure can be shown, improve operating efficiency.
The present invention is to solve above-mentioned technical problem and the technical scheme that adopts is：
A kind of micro- water of SF6 equipment tests special joint, is cross valve form, including pressure display end, tester flexible pipe
Interface end, non-return valve end, equipment connectivity port end, the inside of micro- water test special joint has a chamber, the chamber
Top be fixedly connected pressure display end, bottom thread connection non-return valve end, the side connecting test instrument in the left and right sides is soft
Interface tube end, the opposite side connection equipment connectivity port end in the left and right sides, pressure display end is relative with non-return valve end, tester
Device hose connection end is relative with equipment connectivity port end.
Further, the pressure display end is a pressure gauge.
Further, the tester hose connection end be the stepped pipe of tool formed fill in extrusion sealed interface,
The big pipe one end of diameter connects the chamber, and the other end connects one end of the little pipe of a diameter, and the other end of the little pipe of diameter connects
The flexible pipe of micro- water tester is connect, and the port of the other end of the little pipe of diameter arranges the big joint plastics mouth of an elasticity, diameter
The diameter of little pipe matches with the diameter of the flexible pipe of micro- water tester.
Further, the non-return valve end is a needle-valve, is threadedly coupled with the chamber, and the head at non-return valve end stretches into institute
State the inside of chamber.
Further, equipment connectivity port end is with an extension tube and an internal thread tube head, the extension tube one
End is connected with the chamber, and the other end is connected with internal thread tube head, and a sealing gasket is arranged in internal thread tube head, and internal thread tube head can
Independent to rotate, internal thread tube head can coordinate with the tube head of SF6 equipment.
The invention has the beneficial effects as follows, the pressure value of SF6 equipment is shown in real time by pressure display end, connected using equipment
Port end causes simple and convenient with the attended operation of SF6 equipment, and non-return valve end can be rapidly closed in failure, prevents gas leakage etc. from endangering
Harmful generation.Present configuration is reasonable in design, design typification unification, simple to operation, is conducive to standardization job on-the-spot
Implement.
Description of the drawings
Fig. 1 is the overall structure diagram that the micro- water of SF6 equipment of the present invention tests special joint.
Each component names are as follows in figure：
A- pressure display ends, B- tester hose connections end, C- non-return valves end, D- equipment connectivity port end
Specific embodiment
Describe the present invention below in conjunction with the accompanying drawings.
With reference to Fig. 1, the micro- water of SF6 equipment of the present invention tests special joint, is cross valve form, including four functional areas
Domain：Pressure display end A, tester hose connection end B, non-return valve end C, equipment connectivity port end D, micro- water test is special
The inside of joint has a chamber, and pressure display end A, bottom thread connection non-return valve end C are fixedly connected at the top of the chamber,
Side connecting test instrument hose connection end B in the left and right sides, the opposite side connection equipment connectivity port end in the left and right sides
D, pressure display end A are relative with non-return valve end C, and tester hose connection end B is relative with equipment connectivity port end D.
Pressure display end A is a pressure gauge, can in real time show the pressure value of SF6 equipment.
Tester hose connection end B be the stepped pipe of tool formed fill in extrusion sealed interface, the big pipe one of diameter
The end connection chamber, the other end connects one end of the little pipe of a diameter, and the other end of the little pipe of diameter connects micro- water tester
Flexible pipe, and the port of the other end of the little pipe of diameter arranges a big joint plastics mouth of elasticity, the diameter of the little pipe of diameter
Match with the diameter of the flexible pipe of micro- water tester.When using, firmly joint plastics mouth is pressed down, while by micro- water tester
Flexible pipe fill in the little pipe of diameter, by then loosing one's grip that the extrusion sealing of the flexible pipe of micro- water tester is solid, this design behaviour
Make easy, good sealing effect.
Non-return valve end C is a needle-valve, is threadedly coupled with the chamber, and the head of non-return valve end C stretches into the interior of the chamber
Portion, runs into emergency or needs to be turned off rapidly when closing valve, is used conveniently and safely.
Equipment connectivity port end is that D has an extension tube and an internal thread tube head, described extension tube one end and the chamber
