Description
Technical field
The utility model relates to sulfur hexafluoride gas density relay, specifically a kind of sulfur hexafluoride gas density relay
Detection and analysis connector.
Background technique
It improves with the development of science and technology, sulfur hexafluoride gas is opened as the sulfur hexafluoride that outstanding arc-extinguishing medium is widely used in
In pass and hermetically sealed combined electrical apparatus GIS (HGIS), gradually replacing pervious heavy wool formula, less oil, vacuum type breaker.Cause
To have used sulfur hexafluoride gas, these equipment have small in size, light-weight, capacity is big, unit assembled window, maintenance maintenance amount are few etc.
Advantage, and these advantages are all that conventional circuit breaker is incomparable.
Due to sulfur hexafluoride gas simultaneously be also a kind of greenhouse gases, resolved under high temperature and high pressure environment hydrogen fluoride,
The noxious materials such as sulfur dioxide, sulfur tetrafluoride, hydrogen sulfide, these gases can cause tissue edema after sucking lung tissue by human body,
Lung's oxygen exchange is influenced, human body death by suffocation due to anoxic is caused.In order to avoid the appearance of above situation, need to equipment
Sulfur hexafluoride gas carries out being periodically detected analysis, to determine that equipment can operate normally.
From the point of view of current equipment operation maintenance, when carrying out being periodically detected analysis using detection and analysis instrument, tradition
On equipment and the connection that tests and analyzes between instrument it is inconvenient, connector is operated very cumbersome using being threadedly coupled, and
Connection effect defective tightness not can be effectively controlled and ensure safe operation in pipeline gas transmission process.
Utility model content
Problem in view of the prior art, the utility model provide a kind of energy quick online detection, improve equipment and test and analyze
Connector is used in the sulfur hexafluoride gas density relay detection and analysis of efficiency.
The utility model is realized by following technology:
A kind of sulfur hexafluoride gas density relay, which tests and analyzes, uses connector, including relay ontology, connector, connector and
Conduit；Shrinkage pool is provided on the end face of the relay ontology, the connector is placed in shrinkage pool, and the connector is mounted on institute
It states above connector；The conduit penetrator and connector, are passed through the rear cover of relay ontology；It is provided with out in the connector
Close ball valve and flow control valve.
Further, sealing ring is placed among the relay ontology and connector.
Further, the internal layer of the conduit is Teflon pipe, and outer layer is using heat-shrinkable T bush made of inhibiting tape glue.
Further, the switching ball is single-piece ball valve.
The utility model use the utility model has the advantages that increase switching ball and flow control valve inside connector, be convenient for
It quickly adjusts and tests when being tested and analyzed to sulfur hexafluoride gas density relay, reduce sulfur hexafluoride gas density relay and tear open
Number is unloaded, sulfur hexafluoride gas density relay service life is extended.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference meaning: 1, relay ontology；2, connector；3, connector；4, conduit；5, sealing ring；6, switching ball；
7, flow control valve.
Specific embodiment
In order to make the technical solution of the utility model, purpose and its advantage more clearly, below in conjunction with attached drawing and implementation
Example, is further explained explanation to the utility model.
As shown in Figure 1, a kind of sulfur hexafluoride gas density relay, which tests and analyzes, uses connector, including relay ontology 1, company
Fitting 3, connector 2 and conduit 4；It is provided with shrinkage pool on the end face of relay ontology 1, internal screw thread is provided in shrinkage pool, connector 3 revolves
It closes in shrinkage pool, connector 2 screws on connector 3；4 penetrator 2 of conduit and connector 3, after being passed through relay ontology 1
Lid；Switching ball 6 and flow control valve 7 are provided in connector 2, the input port of the connection switch ball valve 6 in connector 2 of conduit 4 is opened
The delivery outlet for closing ball valve 6 is connect with the input port of flow control valve 7, and the delivery outlet of flow control valve 7 is connect with conduit 4 again.
It is placed with sealing ring 5 among relay ontology 1 and connector 3, for preventing sulfur hexafluoride gas from leaking and adjusting
The gap of relay ontology 1 and connector 3.
The internal layer of conduit 5 is Teflon pipe, and for outer layer using heat-shrinkable T bush made of inhibiting tape glue, good airproof performance can be effective
Prevent sulfur hexafluoride gas from leaking.
Switching ball 6 uses single-piece ball valve, and degree of regulation is relatively high.
Connector 3 is the cylinder of the T-type longitudinal section with through-hole, and surface is equipped with external screw thread.
Several annular recess are provided on connector 2, for placing sealing ring.
Above description is merely a prefered embodiment of the utility model, for those skilled in the art, is not taking off
Under the premise of the implementation principle of the utility model, it can still modify to the embodiment, and corresponding modification is also answered
It is considered as the protection scope of the utility model.
