Description
Technical field
The present invention relates to a kind of engineering part, relate in particular to a kind of joint.
Background technology
Positive-pressure air respirator is equipped as respiratory protection, is widely used in the every field such as fire-fighting and rescue, metallurgy, chemical industry, boats and ships and army.Positive-pressure air respirator is comprised of cylinder package, pressure-reducing valve, face shield, steam supply valve and back board assembly.During use, first will be full of the compressed air of 30Mpa in gas cylinder, then gas cylinder is connected with pressure-reducing valve on air respiratorresuscitator; When bottle valve was opened, the compressed air in gas cylinder was introduced into pressure-reducing valve, then entered steam supply valve by middle pressure pipe carry out the secondary decompression after the one-level decompression, entered at last face shield and breathed for the user.
In the prior art, between gas cylinder and pressure-reducing valve, traditional connected mode is with being threaded.But cause it to have larger operating pressure because be full of Compressed Gas in gas cylinder, for fear of meeting accident, must design the darker connecting thread interlock degree of depth between gas cylinder and pressure-reducing valve, more than will twisting handwheel rotation multi-turn with hand when so just having caused gas cylinder to be connected with pressure-reducing valve, pressure-reducing valve and cylinder interface could be screwed to the sealing locking state.According to " self-supporting open type scuba diving " national Specification (GB/T16556-2007), being connected between gas cylinder and pressure-reducing valve can not be by instrument, can only be by manually completing, and such connected mode is time-consuming but also effort not only.In addition, if the angle of cylinder interface and relief valve seam does not have complete matching, although also can cause with the feel feel and be screwed to the end but the actual situation generation that does not reach sealing, this will cause potential personal injury dangerous to the user, especially in the situation that fire-fighting and rescue is raced against time, adopt the shortcoming that this connected mode wastes time and energy to seem particularly outstanding.
Summary of the invention
The purpose of this invention is to provide a kind of Quick Connect Kit, this Quick Connect Kit can be realized quick, accurate, safe being connected between gas cylinder and pressure-reducing valve, thereby eliminate due to the loaded down with trivial details potential danger that causes that is connected between gas cylinder in prior art and pressure-reducing valve, have an accident when avoiding air respiratorresuscitator work, guarantee the safe handling of positive-pressure air respirator.
In order to reach the foregoing invention purpose, the invention provides a kind of Quick Connect Kit, it is located between gas cylinder and pressure-reducing valve, and this Quick Connect Kit comprises a joint male end and is connected and be used for the joint female end be connected with the joint male end, and wherein, this joint male end comprises:
One fixed cover, it is connected with described gas cylinder thread;
