Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
If Fig. 3 is to shown in 6, the offer one pressure early warning sealing cap 2 of the embodiment of the present invention, including cap seat 21, elastic telescopic circle 22, compacting ring 23 and O-ring seal 24, the cavity being internally provided with through cap seat 21 of cap seat 21, elastic telescopic circle 22, compacting ring 23 and O-ring seal 24 are arranged in cavity, dividing plate 25 it is provided with in cavity, dividing plate 25 is convexly equipped with the conical inserting 26 in the pipe end being inserted into pipe joint 1 towards one end of cap seat 21 connecting tube joint 1, and O-ring seal 24 is arranged between the inwall of conical inserting 26 and pipe joint 1.The pressure early warning sealing cap 2 of the present invention is mainly used in sealing the pipe end 11 pipe joint 1 in planar structure and pressure early warning, therefore conical inserting 26 is set, this conical inserting 26 can be utilized to carry in O-ring seal 24 is inserted into the pipe end 11 of pipe joint 1 seal, good sealing effect, the taper surface of conical inserting 26 also has guide effect simultaneously, can be easy to both assemblings with pipe joint 1 when whole pressure early warning sealing cap 2 is connected.
Preferably, the spacing between outer surface and the cavity inner wall of cap seat 21 of conical inserting 26 is more than the wall thickness of pipe joint 1.By the spacing between the cavity inner wall of conical inserting 26 and cap seat 21 being set greater than the wall thickness of pipe joint 1, can so that pipe joint 1 is connected with cap seat 21 time, can be limited in smoothly between conical inserting 26 and cavity inner wall.
More preferably, the periphery of conical inserting 26 is also positioned at its non-end position annular and offers a circle mounting groove, in O-ring seal 24 is fixed on mounting groove and part protrudes from the outer surface of conical inserting 26.By arranging this mounting groove, O-ring seal 24 can be made to be fixed in conical inserting 26, prevent pipe joint 1 with cap seat 21 in an assembling process, O-ring seal 24 is shifted over, and then makes the seal failure between pipe joint 1 and cap seat 21.
In a preferred embodiment of the invention, cavity includes first paragraph cavity, second segment cavity and the 3rd section of cavity that the diameter set gradually becomes larger, and wherein, dividing plate 25 is arranged in the 3rd section of cavity.
Concrete, the 3rd section of cavity is divided into the first installation cavity for installing compacting ring 23 and is used for installing the second installation cavity of pipe joint 1, the first installation cavity and the second installation cavity and is connected by the through hole 27 running through dividing plate 25 and conical inserting 26 by dividing plate 25.By by compacting ring 23 be used for installing the chamber dividing plate 25 of pipe joint 1 and split, when can effectively prevent pipe joint 1 in the cavity screwing in cap seat 21, compacting ring 23 is extruded, and then effectively prevent compacting ring 23 from deforming, increase the service life.
Elastic telescopic circle 22 is arranged in second segment cavity, its extend partially in the 3rd section of cavity and with compacting ring 23 grafting.
Another preferred embodiment as the present invention, setting table terrace 28 between first paragraph cavity and second segment cavity, the first slot is offered on step surface 28, elastic telescopic circle 22 includes expanding ring body 221, the perimembranous of expanding ring body 221 abuts with the wall of second segment cavity, the perimembranous of expanding ring body 221 is respectively facing that first paragraph cavity is extended to be had the first Plug Division 222 and have the second Plug Division 223 towards second segment cavity is extended, first Plug Division 222 is plugged in the first slot, the second Plug Division 223 and compacting ring 23 grafting.By the perimembranous of elastic telescopic circle 22 is abutted with second segment cavity, and two Plug Divisions respectively with the first slot and compacting ring 23 grafting of step surface 28, can make between elastic compression circle 22 with cap seat 21, be connected between elastic compression circle 22 and compacting ring 23 relatively reliable, the problem that seal failure will not occur at the sealing of the pressure early warning sealing cap 2 so enabling to the present invention, improves the sealing effectiveness of pressure early warning sealing cap 2.
In the present embodiment, the first slot is the cannelure being opened on step surface 28.
Preferably, compacting ring 23 being provided with through hole, the centrage of through hole overlaps with the centrage of cavity.
As another preferred embodiment of the present invention, arranging air pressure display pin 29 in first paragraph cavity, expanding ring body 221 is provided for the second slot of grafting air pressure display pin 29 near the side of air pressure display pin 29.By arranging air pressure display pin 29 in first paragraph cavity, and air pressure is shown end and elastic telescopic circle 22 grafting of pin 29, the connection between air pressure display pin 29 and elastic telescopic circle 22 can be made reliable, stop the hidden danger that conventional pressure display pin 29 comes off, increase the accuracy of air pressure display pin 29 detected air pressure.
It should be noted that, the pressure display pin 29 of the present embodiment is arranged on elastic compression circle 22 and pressure display pin 29 can move up and down along with elastic telescopic circle 22 thus is positioned at cavity or stretches out cavity, and operator can be according to the size of the position judgment internal pressure of pressure display pin 29 with ambient pressure.General, when pressure display pin 29 stretches out pressure early warning sealing cap 2, explanation internal pressure is more than ambient pressure.Preferably pressure display pin 29 is positioned on the centrage of first paragraph cavity of cavity.
In the present embodiment, the cap seat 21 of pressure early warning sealing cap 2 can be polyformaldehyde with the material of compacting ring 23, and the material of elastic telescopic circle 22 and O-ring seal 24 is compounded rubber, preferably neoprene and the mixture of chlorohydrin rubber.
The embodiment of the present invention also provides for a kind of air-conditioner, pressure early warning sealing cap including above-mentioned any embodiment, on the vaporizer of the air-conditioner that this pressure early warning sealing cap may be mounted at orifice throttle, it is used for the pipe joint that end face is plane or diverter seals and pressure early warning.
The know-why of the present invention is described above in association with specific embodiment.These describe the principle being intended merely to explain the present invention, and can not be construed to limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present invention, within these modes fall within protection scope of the present invention.
