Abstract

SF6 residual gas manual release device, mainly used SF6 air supplement unit's the tonifying qi mouth and the remaining gas release of pipeline, its SF6 residual gas manual release device, including the check valve, the check valve is installed on the SF6 gas replenish air cock, connect a nut on the characterized by SF6 gas replenish air cock, nut connecting thread sleeve, be equipped with thimble and thimble seat in the screw sleeve, the thimble sets up on the thimble seat, the handle is connected to the screw sleeve other end, the handle is equipped with the air vent, the thimble seat communicates with each other with the handle. The utility model discloses the injury that has caused limb of the human body when having avoided blind emission or not having had fixed thimble mechanical extrusion discharging the operation, the security is higher.

Description

SF6Residual gas hand release

Technical field

This utility model is mainly used in large-scale let-down stations, power plant, power station combined electrical apparatus (GIS) dielectric SF₆Gas After Bu Chonging, the residual gas release of gas filling mouth and pipeline.

Background technology

At present, domestic power plant GIS device supplements SF₆(inertia and harmful gas) device (QI invigorating check valve) does not still have QI invigorating After safe releasing device, work as SF₆When gas supplements complete, the relevant personnel can only be at gas filling mouth check valve core with sharp-pointed metal Pin uses self strength simply to stab top, and side enables to the residual gas release of gas filling mouth and pipeline, although this mode is simple Single, but operational hazards, discharge capacity limited (arranging the cleanest), and there is potential safety hazard.

Summary of the invention

This utility model provides safety higher and discharges clean SF₆Residual gas hand release.

SF₆Residual gas hand release, including check valve, check valve is arranged on gas filling mouth, it is characterized in that QI invigorating Connecting a nut on mouth, nut connects screw shell, is provided with thimble and thimble seat in screw shell, and thimble is arranged on thimble seat On, screw shell connects handle and communicates with the passage of handle, SF₆Residual gas is through thimble seat, screw shell and handle Passage is discharged.I.e. handle is provided with passage.

Described thimble seat is a cylinder, is provided with some dowels in the middle of cylinder, and dowel connects thimble.

Described screw shell one end is for having female sleeve, and the other end is provided with steam vent.

This utility model drives screw shell to rotate by slow rotary handle and screw shell screws in the screw thread of nut In, along with the rotation of handle makes thimble hold out against inner elements of check valve, inner elements of check valve is reverse return under the pressure effect of thimble, beats Open gas filling mouth release channel, thus by SF₆Gas slowly discharges.

Human body limb is caused when avoiding blindly discharge or the fixing thimble mechanical presses emissions operation of nothing by this utility model Injury, safety is higher.
