Description
Technical field
The present invention relates to a kind of engineering part, particularly relate 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 made up 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 the pressure-reducing valve on air respiratorresuscitator; When bottle valve is opened, the compressed air in gas cylinder is introduced into pressure-reducing valve, then enters steam supply valve by middle pressure pipe and carry out secondary pressure after one-level decompression, finally enters face shield and breathes for user.
In the prior art, traditional between gas cylinder with pressure-reducing valve connected mode is with being threaded.But cause it to have larger operating pressure because be filled with Compressed Gas in gas cylinder, in order to avoid meeting accident, the darker connecting thread occlusion degree of depth must be designed between gas cylinder and pressure-reducing valve, which results in time gas cylinder is connected with pressure-reducing valve and twist more than handwheel multi-turn rotation with hand, pressure-reducing valve and cylinder interface could be screwed to sealing locking state.According to the national Specification of " self-supporting open type scuba diving " (GB/T16556-2007), the connection between gas cylinder and pressure-reducing valve can not by instrument, and can only pass through manually to complete, such connected mode is not only time-consuming but also require great effort.In addition, if the angle of cylinder interface and relief valve seam does not have complete matching, though also can cause with feel feel be screwed to the end reality do not reach sealing situation occur, this causes potential danger of personal injury by user, especially, when fire-fighting and rescue is raced against time, the shortcoming that this connected mode wastes time and energy is adopted to seem particularly outstanding.
Summary of the invention
The object of this invention is to provide a kind of Quick Connect Kit, this Quick Connect Kit can realize connection quick, accurate, safe between gas cylinder and pressure-reducing valve, thus eliminate the potential danger caused due to loaded down with trivial details connection the in prior art between gas cylinder with pressure-reducing valve, have an accident when avoiding air respiratorresuscitator to work, guarantee the safe handling of positive-pressure air respirator.
In order to reach foregoing invention object, 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 a joint female end for being connected with joint male end, and wherein, this joint male end comprises:
One fixed cover, it is connected with described gas cylinder thread;
One plug, its underpart is located in described fixed cover, and is fixedly installed with fixed cover in the axial direction, and the outer circumference surface of this plug bottom is provided with the groove of an annular, and described plug inside has the passage of an axis;
Above-mentioned joint female end comprises:
The interior big envelope of one hollow, the bottom of described plug can be placed in interior big envelope, the top of this interior big envelope is provided with several steel bead grooves arranged along its circumferential direction, in each steel bead groove, all correspondence is provided with a steel ball, each steel ball can be arranged in the groove of described plug, this interior big envelope outer wall is provided with one first boss, and the inwall of interior big envelope is provided with one second boss;
The base of one hollow, its fixed cover is located at the bottom of described interior big envelope, and this base is also threaded with pressure-reducing valve, and the outer wall of this base is provided with one the 3rd boss;
One piston, it is located in described interior big envelope, and is set to move axially between the bottom of interior big envelope and the second boss, this piston offers the passage of an axis;
One first spring, it is in axial direction located between piston and base, to apply an axial force to piston;
One female end main body, it is sheathed on outside interior big envelope and base, and is set in axial direction to move between the first boss and the 3rd boss;
One the second spring axially arranged, is located between described female end main body and base, to apply an axial spring forces to female end main body.
In Quick Connect Kit of the present invention, joint male end and gas cylinder fixed seal connection, joint female end and pressure-reducing valve fixed seal connection, realize gas cylinder by the connection of joint male end and joint female end and be connected with the quick of pressure-reducing valve.During use, the plug bottom of joint male end to be extend in hollow in big envelope, and the power of one downward (namely towards the direction of joint female end) is applied to plug, piston is pressed down by its resistance overcoming the first spring, until the steel ball on interior big envelope embeds in the groove on plug, under the simultaneously effect of axial spring forces that applies at the second spring of female end main body, upwards (namely towards the direction of joint male end) is mobile, overlap until the upper end of female end main body contacts with the first boss, at this moment joint male end is in joint female end the state of being fixedly connected with, achieve the connection between gas cylinder and pressure-reducing valve.Compressed Gas from gas cylinder out after, by the axial passage on plug, the axial passage on piston and base enter pressure-reducing valve decompression.
When pressure-reducing valve unloads from gas cylinder by needs, as long as apply the power of one downward (namely towards the direction of pressure-reducing valve) in female end main body, the resistance that so the first spring can overcome the second spring applies the power of one upwards (namely towards the direction of joint male end) on piston, piston is upwards pushed up, and then plug is ejected interior big envelope.
Further, Quick Connect Kit of the present invention also comprises an air inlet filter core, and it is fixed in base near pressure-reducing valve.Arranging air inlet filter core is that Compressed Gas in order to discharge gas cylinder carries out purification filtering, the normal work of proterctive equipment and the cleaning of air used.
Further, above-mentioned air inlet filter core is connected with whorl of base.
Further, Quick Connect Kit of the present invention also comprises one handle, and its fixed cover is located at outside female end main body, this handle has the force boss applying axial force.This handle person of being easy to use butt joint female end force is set.
Further, in Quick Connect Kit of the present invention, between described plug and fixed cover, be provided with a back-up ring, for realizing between plug and fixed cover being fixedly installed in the axial direction.
Further, in Quick Connect Kit of the present invention, between described plug and gas cylinder, be provided with one first sealing ring.
Further, in Quick Connect Kit of the present invention, between described piston and interior big envelope, be also provided with one second sealing ring.
Further, in Quick Connect Kit of the present invention, between described base and pressure-reducing valve, be also provided with one the 3rd sealing ring.
Further, in Quick Connect Kit of the present invention, between described interior big envelope and base, be provided with one the 4th sealing ring.
The setting of above-mentioned sealing ring can not be leaked gas after the gas in order to ensure in gas cylinder is compressed release.Above-mentioned each sealing ring can adopt conventional O RunddichtringO.
With existing gas cylinder with between pressure-reducing valve traditional be threaded compared with, the advantage of Quick Connect Kit of the present invention is:
1) gas cylinder and pressure-reducing valve can be fixedly connected with quickly and easily;
2) without the need to the strength of user's overspending;
3) gas cylinder can not be produced due to the angular misalignments between interface and pressurizing valve does not have Packed situation;
4) connected mode is simple, simple operation, saves assembling time;
5) there is higher security performance, avoid potential danger when air respiratorresuscitator uses.
