Description
Technical field:
The utility model relates to a kind of pressure-display device, specifically a kind of needle-valve sealing configuration of gas extinguishing system pressure-display device.
Background technique:
Adopt the getting type that directly links to each other between the common vessel valve of gas extinguishing system and the pressure-display device, in storage, transportation, installation process, because collision, vibrations cause the damage of pressure-display device, cause jointing to leak, just can carry out after need be when changing pressure-display device extinguishing agent in the bottle group or gas emptying, the loss that brings is big, and consequence is serious.
Also have between vessel valve and the pressure-display device and adopt vehicle to use valve inside as the Placement that opens and closes pressure source, vehicle is just used the structure of plane motive sealing with valve inside, long-time the use Sealing is damaged, cause leakage, cause damage.
Summary of the invention:
For avoiding the deficiencies in the prior art part, the utility model provides the needle-valve sealing configuration of gas extinguishing system pressure-display device, and the utility model has guaranteed the sealing reliably of pressure-display device and vessel valve jointing and changed pressure-display device quickly and easily by the valve pad of needle-valve and special construction.
The gas extinguishing system pressure-display device is made up of pressure gauge and needle-valve, needle-valve is by being made up of valve body, flower shape sealing gasket, pin, spool, Returnning spring and spring seat, valve body one end is an outside thread, be used for connection with vessel valve, the valve body the other end connects pressure-display device, spring seat is installed in the valve body, Returnning spring mounts elastically, Returnning spring withstands spool, one conical surface is arranged on the spool, corresponding positions is equipped with a conical surface in the valve body, and the conical surface of spool is provided with sealing material, two cone match.In the valve body that links to each other with pressure-display device colored shape sealing gasket is housed, has guaranteed sealing reliably between needle-valve and the pressure-display device, the outside thread by the valve body front end during use connects and kills " O " shape seal ring and guarantee that needle-valve and vessel valve seal reliably.When being unkitted pressure-display device, be screwed to the position after, join with vessel valve again and make locating stud, prevent to become flexible.
The utility model valve body is provided with sealing gasket, sealing gasket adopts the flower grommet type seal, material is nonmetal, and described colored shape sealing gasket is meant that the periphery at sealing gasket is provided with one or more projectioies, and described projection is the projection of circular arc, triangle or common petal shape.A plurality of projectioies are evenly arranged.Pressure-display device malcompression flower shape sealing gasket does not push up spool yet, and pressure by extinguishing agent in the bottle or gas and Returnning spring be the outside roof pressure of spool, the conical surface on the spool and the cone match on the valve body, assurance excellent sealing performance; When loading onto pressure-display device, pressure-display device compresses colored shape sealing gasket and pushes up spool simultaneously, and the spool compression reseting spring guarantees with pressure-display device good connection and reliable sealing are arranged by colored shape sealing gasket in the valve body and internal thread.For preventing that valve body from rotating, when valve body is linked to each other with vessel valve, treat that screw thread is screwed to the position after, join with vessel valve again and make locating stud, prevent to become flexible.
The utility model is simple in structure, and is easy for installation, can effectively protect pressure gauge not to be damaged under the prerequisite that guarantees sealability.
