Abstract
The utility model discloses an SF6 gas dismounting-free safety valve, which comprises a valve body, wherein a density relay interface, a connecting switch and a test interface are arranged on the valve body, the connecting switch and the test interface are respectively communicated with the density relay interface through a four-way valve, and a valve switch is arranged between the connecting switch and the four-way valve. The SF6 gas dismounting-free safety valve has the advantages that the structure is simple, the use is convenient, and the micro water measurement and the gas supplementation can be conveniently carried out on an SF6 switch. Through the arrangement of the valve switch, the dismounting is not needed during the monitoring and the checking, one person can independently complete the operation, convenience is realized, and the time and the labor are saved. Meanwhile, the damage to a sealing surface and a sealing ring caused by the dismounting can be avoided.
Description
Technical field
The utility model relates to SF
6Gas detection equipment refers to a kind of SF especially
6Gas exempts to dismantle safety valve.
Background technique
SF
6SF in circuit breaker and mutual inductor
6Gas is with a lot of monitoring equipments and instrument outward, for SF
6The safe operation of circuit breaker and mutual inductor is most important, therefore generally at SF
6Circuit breaker and mutual inductor are arranged with safety monitoring device outward or instrument carries out checksum test; But the checksum test of existing most monitoring equipment or instrument all must carry out disassembly-type after power failure detects and overhauls, and brings very large inconvenience to the staff, has improved simultaneously labor intensity; And then need to provide a kind of equipment or instrument that can carry out safety monitoring not cutting off the power supply.
The model utility content
The utility model proposes a kind of SF
6Gas exempts to dismantle safety valve, need not to dismantle SF
6Gas detection equipment can be completed SF
6The monitoring of gas and verification facilitate, save time, laborsaving.
The technical solution of the utility model is achieved in that a kind of SF
6Gas exempts to dismantle safety valve, comprises valve body, and described valve body is provided with the density monitor interface and by connecting valve and test interface that four-way valve and density monitor interface are communicated with respectively, is provided with valve switch between described connecting valve and four-way valve.
As preferably, described valve switch and four-way valve removably connect.
As preferably, described valve body seals by seal ring.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, easy to use, can be very easily to SF
6Switch carries out little water gaging and reaches SF
6Switch carries out tonifying Qi.The setting of valve switch in monitoring with need not dismantle during verification, gets final product people's complete independently and operates, and facilitates, saves time, laborsaving; Avoided simultaneously because of the sealing surface that dismounting causes, the infringement of seal ring.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the fundamental diagram of the utility model when normally moving;
Fig. 2 is the fundamental diagram of Fig. 1 when monitoring verification;
Fig. 3 is Fig. 1 structural representation.
In figure: 1, density monitor interface; 2, connecting valve; 3, test interface; 4, valve switch; 5, four-way valve.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1 to Fig. 3, a kind of SF
6Gas exempts to dismantle safety valve, comprises valve body, and described valve body is provided with density monitor interface 1 and by four-way valve 5 and connecting valve 2 and test interface 3 that density monitor interface 1 is communicated with respectively, is provided with valve switch 4 between described connecting valve 2 and four-way valve 5.Described valve switch 4 removably connects with four-way valve 5, and described valve body seals by seal ring.
When normal operation, connect density monitor by density monitor interface 1, and connect connecting valve 2, valve switch 4 closures, connecting valve 2 forms gas return path with density monitor; The gas return path at test interface 3 places disconnects; SF
6Gas exempts to dismantle arranged at safety valve in normal operating condition.Detecting, during calibration equipment, connecing density monitor by density monitor interface 1, and connect connecting valve 2, valve switch 4 disconnects, and the gas return path at test interface 3 places is closed, SF
6Gas exempts to dismantle arranged at safety valve in monitoring, verification state.
The utility model is realized need not outage, be need not dismounting by valve switch 4 when monitoring, verification, can realize SF
6The monitoring of gas and verification, convenient, laborsaving, save time; Avoided simultaneously because of the sealing surface that dismounting causes, the infringement of seal ring.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
