Abstract
The utility model discloses a safety pressure measuring tie-in which comprises a body (1), an anti-withdrawal cover (2), a steel ball (3), a steel ball retaining ring (4), a spring (5), a spring retaining ring (6) and a closing ring (7). The utility model is characterized in that the tail-end of the body is provided with the closing ring (7) on which the spring retaining ring (6) is positioned, the spring (5) installed on the spring retaining ring is provided with the steel retaining ring (4) which pushes the steel ball (3), the head portion of the body (1) is sealed by the anti-withdrawal cover (2), and an annular convex is arranged on the body between the anti-withdrawal cover (2) and the steel ball (3). The safety pressure measuring tie-in is delicate in design, small and skilful, and safe and reliable, which has no influences on the normal use of gas channel and gas appliances and brings great convenience for the normal detection of gas appliances.
Description
Technical field
The utility model relates to a kind of pipe coupling, is a kind of safety type pressure measuring tie-in specifically.
Prior art
At present, when the tour personnel of technical supervision department or gas company will detect Gas appliance in the gas industry, valve, gas meter outlet connection place are detected before the kitchen range, valve connects sebific duct before pulling out kitchen range, turn on the gas meter joint, pressure condition is detected, again the detection facility dismounting is restored to the original state after detecting.Instrument and material that each dismounting needs are heavy, operate very loaded down with trivial details.Installing/dismounting is easy to cause gas leakage repeatedly, and each dismounting all can cause a certain amount of gas to decrease.And it is long to detect the time that needs, and it is not high to detect work efficiency, and there is sizable potential safety hazard in operation under pressure.
Summary of the invention
In view of this, the purpose of this utility model be to provide a kind of safe, detect the special test device reliably, easily, it can not influence the state of Gas appliance work at any time implements down to detect, and has improved the detection work efficiency greatly.
The technical solution of the utility model is: a kind of safety type pressure measuring tie-in, form by body 1, tamper lid 2, steel ball 3, steel ball back-up ring 4, spring 5, check ring 6, collar 7, wherein, be provided with collar 7 at the body afterbody, a check ring 6 is arranged on the collar, mounting spring 5 on check ring, steel ball back-up ring 4 is set on the spring, steel ball back-up ring 4 is pushed a steel ball 3, by 2 sealings of tamper lid, on the body 1 between tamper lid 2 and the steel ball 3 annular projection is arranged at body 1 head.It is fan type spoons that 2 heads are covered in tamper.
The utility model design is exquisite, small and exquisite, safe and reliable, does not influence the normal use of fuel gas path, Gas appliance fully, and the normal detection of Gas appliance is brought great convenience.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a tamper lid structural representation of the present utility model.
Fig. 3 is assemblied in meter connector place schematic representation for the utility model.
Fig. 4 is assemblied in valve place schematic representation before the kitchen range for the utility model.
Among the figure: symbol 1 is represented body, and symbol 2 is represented the tamper lid, and symbol 3 is represented steel ball, and symbol 4 is represented the steel ball back-up ring, and symbol 5 is represented spring, and symbol 6 is represented check ring, and symbol 7 is represented collar.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As Fig. 1, Fig. 2, a kind of safety type pressure measuring tie-in of the present utility model, form by body 1, tamper lid 2, steel ball 3, steel ball back-up ring 4, spring 5, check ring 6, collar 7, wherein, be provided with collar 7 at the body afterbody, one check ring 6 is arranged on the collar, mounting spring 5 on check ring, and steel ball back-up ring 4 is set on the spring, and steel ball back-up ring 4 is pushed a steel ball 3, by 2 sealings of tamper lid, on the body 1 between tamper lid 2 and the steel ball 3, an annular projection is arranged at body 1 head.It is fan type spoons that 2 heads are covered in tamper.
Tamper of the present utility model lid has fan type spoon, need just can open with special tool, and steel ball must just can get out of the way path with thimble, avoided opening by mistake open, misoperation.
Claims (2)
1, a kind of safety type pressure measuring tie-in, form by body (1), tamper lid (2), steel ball (3), steel ball back-up ring (4), spring (5), check ring (6), collar (7), it is characterized in that: be provided with collar (7) at the body afterbody, one check ring (6) is arranged on the collar, mounting spring on check ring (5), steel ball back-up ring (4) is set on the spring, steel ball back-up ring (4) is pushed a steel ball (3), by tamper lid (2) sealing, on the body (1) between tamper lid (2) and the steel ball (3), an annular projection is arranged at body (1) head.
