Abstract
The utility model relates to a gas-insulated switchgear explosion-proof device. The explosion-proof device comprises an explosion-proof sheet, a backing ring of the explosion-proof sheet, a sealing ring and fasteners, wherein the explosion-proof sheet and the backing ring are fillingly disposed inside an opening hole of a gas-insulated switchgear bottom board, the explosion-proof sheet is covered with the sealing ring, and the explosion-proof sheet, the backing ring and the sealing ring are connected with the gas-insulated switchgear bottom board by the fasteners. The beneficial effects of the gas-insulated switchgear explosion-proof device are that: by employing just one gas-insulated switchgear pressure-relief explosion-proof device, explosion is prevented, the design of the explosion-proof device is simplified, the explosion-proof device can be rapidly assembled, and the sealing performance and the reliability of the assembled explosion-proof device can be ensured.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment, the decompression anti-explosion device that especially gas-filling cabinet is used.
Background technology
Along with greatly developing of switch industry, a lot of producers have all developed gas isolated switch cubicle, i.e. gas-filling cabinet product, and its core is exactly the gas tank that is filled with certain pressure insulating gas.A lot of producers may not design explosion-protection equipment, or have designed comparatively complicated explosion-protection equipment and be assembled to gas tank.If while there is no explosion-protection equipment, electric loop, as broken down, may cause gas tank blast, forms fragment impact etc., and danger is larger.If when explosion-protection equipment is comparatively complicated, cost is higher on the one hand, how assembly easily causes gas tank to leak the fault that causes complete machine on the other hand.Develop a kind of simple in structure, good reliability, explosion-protection equipment that cost is lower is extremely urgent.
Utility model content
For the problems referred to above, main purpose of the present utility model is to provide a kind of gas-filling cabinet explosion-protection equipment, for simplifying the structure of explosion-protection equipment, and can guarantee to be equally assembled to sealing property and the security performance of gas tank.
At gas tank base plate, open circular hole, the safety during as gas tank explosion is drawn hole, and at plate outer side welding screw, the explosion-protection equipment of simplified design is assembled to base plate by double-screw bolt, thinking of dealing with problems of the present utility model that Here it is.
Concrete technical scheme is as follows:
A gas-filling cabinet explosion-protection equipment, comprises the burst disk and the grommet thereof that are filled in gas tank base plate perforate perforate, is overlying on the sealing ring on burst disk outward, and the securing member that this burst disk and grommet thereof, sealing ring are connected with gas tank base plate.
Preferably, described securing member comprises double-screw bolt and matching nut, packing ring.
Preferably, described stud welding is on gas tank base plate.
Preferably, also comprise a fixed head, with the fixing relative position of burst disk and grommet thereof and sealing ring.
The beneficial effects of the utility model are: use a kind of gas-filling cabinet decompression anti-explosion device, can play explosion-proof object, can reach again and simplify explosion-protection equipment design and assemble fast object, also can guarantee sealing property and unfailing performance after assembling simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that explosion-protection equipment is assembled to gas tank base plate.
The 1st, gas tank base plate;
The 2nd, the perforate of gas tank base plate;
The 3rd, explosion-protection equipment grommet;
The 4th, explosion-protection equipment sealing ring;
The 5th, explosion-protection equipment burst disk;
The 6th, securing member;
The 7th, explosion-protection equipment fixed head.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and be easy to understand and understanding with effect, below in conjunction with embodiment, further set forth the utility model.
Refer to Fig. 1, it can be circular hole or other shapes that the gas tank base plate 1 of gas-filling cabinet casing has perforate 2(), in this perforate 2, be provided with gas-filling cabinet riot gear, this riot gear comprises anti-riot 5 and grommet 3, sealing ring 4, anti-riot 5 and grommet 3 are filled in the through hole of gas tank base plate perforate 2, and it is connected with gas tank base plate 1 with the sealing ring 4 covering outward with fixed head 7 by securing member 6, fixed head 7 is in order to the fixing relative position of burst disk and grommet thereof and sealing ring, and is fixed by securing member 6.This securing member 6 comprises double-screw bolt and matching nut, packing ring, and this securing member also can be suitable for equally other conventional connectors and connect.This double-screw bolt can be welded on gas tank base plate 1.
Only for the preferred embodiment of invention, be not used for limiting practical range of the present invention in sum.Be that all equivalences of doing according to the content of the present patent application the scope of the claims change and modify, all should be technology category of the present invention.
Claims (4)
1. a gas-filling cabinet explosion-protection equipment, is characterized in that, comprises the burst disk and the grommet thereof that are filled in gas tank base plate perforate perforate, is overlying on the sealing ring on burst disk outward, and the securing member that this burst disk and grommet thereof, sealing ring are connected with gas tank base plate.
2. device according to claim 1, is characterized in that, described securing member comprises double-screw bolt and matching nut, packing ring.
