Territory.Pressure measuring tie-in is very universal in we live, and not only lives, water conservancy company, Utilities Electric Co., sewage treatment plant
Etc. all apply very universal, particularly in fire protection technical field, fire hydrant pressure measuring tie-in is also known as fire hydrant measuring cell, many
Function fire-fighting test device, fire hydrant pressure measuring tie-in are the hydrostatic pressings for detecting indoor fire hydrant, discharge pressure, and check water
The special purpose device of rifle fulling water columm.
Pressure measuring tie-in is being widely used the most slowly, and market meeting in constantly exploitation
More and more wide.But traditional pressure measuring tie-in seals structure and there is problems in that sealing reliability is poor, low at system pressure,
Easily producing seepage time in the case of the various instability such as vibrated, sealing property is difficult to be protected；Use not
Portable light, is not suitable at the on-the-spot narrow and small environment of fire protection time space using；Structure is complicated, assembles loaded down with trivial details, production cost
Height, production efficiency is poor, and service life is short, it is impossible to meet the requirement of large-scale production.
For the problem above overcoming prior art to exist, this utility model provides a kind of close structure of pressure measuring tie-in.
Utility model content
This utility model purpose is to provide a kind of pressure measuring tie-in to seal structure, all with solve that prior art deficiency causes
Many defects.
In order to solve the problems referred to above, the technical scheme that this utility model is used is as follows:
A kind of pressure measuring tie-in seals structure, and a kind of pressure measuring tie-in seals structure, including pressure measuring tie-in body, dust guard and from
Envelope spool, it is characterised in that in described pressure measuring tie-in body, top and the bottom are respectively equipped with Self-sealing valve core cavity and spring cavity, described bullet
Spring intracavity is provided with spring, and the bottom of described spring cavity is fixing with the lower end of described spring to be connected, and described self-styled spool is arranged at institute
Stating in pressure measuring tie-in body, match with described Self-sealing valve core cavity in described self-styled spool upper end, with described in the middle part of described self-styled spool
Spring cavity matches, and described self-styled spool lower end is fixing with the upper end of described spring to be connected, and described dust guard includes dust cap
With dust-proof core, described dust-proof core matches with described Self-sealing valve core cavity, and described dust-proof core is arranged at the top of described Self-sealing valve core cavity
End, described dust cap is socketed described pressure measuring tie-in body and dust-proof core.
Preferably, the material that described pressure measuring tie-in body and self-styled spool are selected is carbon steel or rustless steel.
Preferably, the contact surface in the middle part of described pressure measuring tie-in body and described self-styled spool is provided with seal groove, described sealing
The first O it is provided with in groove.
Preferably, described pressure measuring tie-in body is provided with the second O with the contact surface of described dust cap bottom.
Compared to prior art, the beneficial effects of the utility model are:
This utility model preventing dust corrodes；Simple in construction, simple installation；Greatly increase sealing property, in system pressure
Also will not seepage in the case of the various instability such as power is low, vibrated；Decrease pressure measuring tie-in overall length and weight, portable
Lightly, it is particularly suitable at the on-the-spot narrow and small environment of fire protection time space using；Production cost is low, and service life is long, can advise greatly
Mould produces.
Accompanying drawing explanation
Fig. 1 is that a kind of pressure measuring tie-in of the present utility model seals architecture schematic diagram；
Wherein, 1 pressure measuring tie-in body, 2 dust guards, 3 self-styled spools, 4 Self-sealing valve core cavities, 5 spring cavitys,
6 springs, 7 dust caps, 8 dust-proof cores, 9 seal grooves, 10 first O, 11 second O.
Detailed description of the invention
This utility model is done as described below below in conjunction with detailed description of the invention example:
A kind of pressure measuring tie-in seals structure, including pressure measuring tie-in body 1, dust guard 2 and self-styled spool 3, it is characterised in that
