Background technique
At present, pipe coupling is requisite link in pipe-laying process, for being connected and sealed to two gas pipelines, but, when pipe coupling of the prior art is applied in gas pipe line, switch in pipe coupling can be simple and relax operation, coal gas usurped by easy like this switch of opening.In addition, have pressure in gas pipeline, but pipeline of the prior art can not be tested to its pressure, inconvenience controls pipeline internal air pressure size like this.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide one to have antitheft, tamper, also can the overall tamper pressure-measuring meter joint of testing conduit pressure.
For achieving the above object, the present invention is by the following technical solutions: overall tamper pressure-measuring meter joint, comprise nut, described nut top engagement sleeves is provided with tamper cover, anti-clamping ring is provided with between tamper cover and nut, be equipped with pressure-measuring meter joint in tamper cover and nut, in the middle part of pressure-measuring meter joint, be provided with valve inside device.
Wherein, described valve inside device comprises the valve core body be laterally located in pressure-measuring meter joint, and valve core body one end fits is provided with nut, is provided with the second packing ring between valve core body and nut.
Wherein, described pressure-measuring meter joint comprises inner core and urceolus, in urceolus bottom and nut, upper end mounts, the first packing ring is provided with between inner core and urceolus, jump ring is provided with between urceolus and nut, the middle part of described urceolus is arranged and the integrated valve core print seat of urceolus, and described valve core body is located in valve core print seat.
Wherein, offering the first draw-in groove for placing anti-clamping ring, offering the second draw-in groove above the first draw-in groove bottom described nut, described tamper cover inwall is provided with the chuck coordinating clamping with the second draw-in groove.
Wherein, the cross section of described tamper cover is polygonal.
Beneficial effect of the present invention is: the present invention includes nut, and described nut top engagement sleeves is provided with tamper cover, is provided with anti-clamping ring between tamper cover and nut, is equipped with pressure-measuring meter joint, is provided with valve inside device in the middle part of pressure-measuring meter joint in tamper cover and nut; The present invention is provided with tamper cover by coordinating in nut upper end, the flexible clamping that this tamper cover coordinates with nut, effect that is antitheft, tamper can be played, the valve inside device that described test chart joint side is arranged, the air pressure size in gas pipeline can be tested by valve inside device.
