The utility model is compared with prior art products and is had the advantage of following aspect:
1, the utility model can cooperate existing various import at present and homemade recovery system to use, and solves the difficult problem that cold climate can not effectively recharge down.
2, the utility model can be to the quick pumping high vacuum of electric installation (or steel cylinder).
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, sulfur hexafluoride gas is auxiliary to be recharged equipment and comprises vacuum pump 6 and pipeline heat exchanger 2.Pipeline heat exchanger 2 adds interchanger for fin type; Vacuum pump 6 is reciprocating type or rotary vacuum pump, and the highest attainable vacuum value is 10Pa.
Pipeline heat exchanger 2 is threaded a pipe respectively and is being connected equipment interface 1 and steel cylinder interface 4, and equipment interface valve V2 is installed on the pipeline between equipment interface 1 and the pipeline heat exchanger 2, and steel cylinder interface valve V1 is installed on the pipeline between pipeline heat exchanger 2 and the steel cylinder interface 4; On the pipeline between pipeline heat exchanger 2 and the steel cylinder interface 4 tensimeter PG3 is installed; Equipment interface 1 is being connected arm with pipeline between the equipment interface valve V2 by T-valve, and the other end of arm is connecting vacuum pump 6, and vacuum pumping valve V3 is installed on the arm.The ingress of vacuum pump 6 is equipped with digital display vacuumometer VG5.
Steel cylinder interface valve V1, equipment interface valve V2 and vacuum pumping valve V3 are the normal temperature manual valve, and normally closed; Steel cylinder interface valve V1, equipment interface valve V2 are equivalent to urgent manually service valve, when recharging gas, connect electric installation and steel cylinder (or gas-holder) back respectively and open; Vacuum pumping valve V3 only opens when vacuumizing, and prevents that vacuum pump inlet from being damaged vacuum pump by compression shock in the pipeline; Tensimeter PG3 is the mechanical type gas-pressure meter with shockproof function, and expression recharges initial pressure.
Concrete principle of work is as follows:
Self-cleaning function
Under the stress-free situation of affirmation system, equipment interface 1, steel cylinder interface 4 are connected with equipment and steel cylinder respectively, check resistance to air loss, open vacuum pump 6, steel cylinder interface valve V1, equipment interface valve V2 and vacuum pumping valve V3 successively; When operator reach necessary requirement by digital display vacuumometer VG5 observation vacuum tightness, close vacuum pumping valve V3 successively, vacuum pump 6, steel cylinder interface valve V1, equipment interface valve V2 finish this function.
Vacuumize function
When guaranteeing the equipment internal pressure near negative pressure, equipment interface 1 usefulness is hose connection, check resistance to air loss, open vacuum pump 6, equipment interface valve V2 and vacuum pumping valve V3 successively; When operator reach necessary requirement by digital display vacuumometer VG5 observation vacuum tightness, close vacuum pumping valve V3, vacuum pump 6, equipment interface valve V2 successively, finish this function.
