Abstract

The utility model discloses a high-efficient quick connector, which mainly relates to a quick sealing connector for pipeline vacuum pumping, refrigerant filling, leakage detecting and performance testing in refrigeration industry and is particularly adaptable to air-conditioner performance testing having high requirement on new coolants and sealing property. The high-efficient quick connector is structurally composed of a valve body, a valve spool, a return spring, a sealing ring and the like, which is characterized in that the sealing ring made of heat vulcanized rubber or other soft-sealing materials is cured and adhered to a valve spool extension rod processed via shot blasting, and simultaneously, the sealing ring is in multi-lip contacting seal with the inner conical face of the valve body. The improved sealing structure can effectively avoids shortages that conventional sealing rings are easy to expand, break and deform are poor in elasticity and restorability during sealing process, and has the advantages of long service life and reliable sealing effect. Generally, the high-efficient quick connector is in matching connection with a female connector, and the valve spool is ejected after connection, thereby realizing medium circulation.

Description

Efficient connected body fast

Technical field

The utility model relates to a kind of quick connection SEALING FITTING that the refrigeration industry pipeline vacuumizes, fills refrigeration agent, leak detection and testing property, is meant a kind of efficient connected body fast that is specially adapted to new cooling media and the demanding heat pump performance test of sealability specifically.

Background technique

Be used for the traditional jointing valve core structure that air-conditioning vacuumized, filled refrigeration agent, leak detection and testing property at present and push down sealing through briquetting by a planar seal ring, its defective is: one, planar seal ring and spool do not have bonding, in operation of air conditioner under the expansion of the high temperature that produces and refrigeration agent, seal ring easily rises greatly, break, life-span is short, and the seal ring that breaks down will become pipeline rubbish, causes pipeline blockage; Two, because planar seal ring is that face contacts with the sealing of valve outlet end, the sealing surface of seal ring is stressed big, and the seal ring of long-time pressurized easily forms permanent deformation, can not reset, and causes soft seal to lose efficacy.

Summary of the invention

Goal of the invention of the present utility model all provides a kind of seal ring long service life, sealing effect efficient reliably connected body fast in the defective that overcomes prior art.

According to the foregoing invention purpose, embodiment of the present utility model is:

A kind of efficient connected body fast, it comprises the valve body of left and right perforation, the valve body internal channel is equipped with by the spool of Returnning spring pretension sealing pushing tow with by the multiway elastic component of takeing on thrust in the valve body, be provided with seal ring between described spool and the valve body, it is characterized in that described spool has one section outrigger shaft through shot blast by the bonnet location; Described seal ring curing is bonded on the outrigger shaft, and sealing circle and valve body internal conical surface are that many lipped joints touch sealing.

Many lipped joints of described seal ring and valve body internal conical surface touch and are sealed into 2～3 lips.

Described seal ring is that hot vulcanization rubber or other soft sealing material are made.

Described spool left end is provided with blind hole.The leg quantity of described multiway elastic component is 2～8.

Be connected with the female joint supporting on the described valve body with it.

Compared with prior art, spool of the present utility model extends one section outrigger shaft through shot blast, and hot vulcanization rubber or other soft sealing material solidify to be bonded on this outrigger shaft and form seal ring, and seal ring touches sealing with the internal conical surface of valve body with many lipped joints again simultaneously, it is little that sealing configuration after the improvement has a sealing contact surface, pressurized is little, is difficult for forming permanent deformation, and elastic recovery properties is good, be difficult for expanded by heating, advantages such as can not cause pipeline blockage, sealing life is long, and sealing effect is reliable.

Embodiment

Embodiment is described in detail the utility model again below with reference to accompanying drawing.

As Fig. 1～shown in Figure 2,1-valve body, 2-multiway elastic component, 3-Returnning spring, 4-spool, 5-seal ring, 6-bonnet, 7-outrigger shaft, 8-blind hole.

A kind of efficient connected body fast, the valve body 1 that connects about it comprises, this valve body right-hand member has the internal conical surface structure, the valve body internal channel is provided with spool 4, the left side of this spool is provided with blind hole 8, and its effect is in the valve core reset process, plays balanced action under the air-flow effect, it is tiltedly outer that spool is difficult for, to guarantee the reliability of spool 4 sealings.This spool left end is set in again on the multiway elastic component 2 that can shrink tensioner simultaneously, and 6 legs of this multiway elastic component are by the interior shoulder thrust of valve body 1.

Described spool also is set with the Returnning spring 3 that two ends difference pushing tow is takeed on outward outside multiway elastic component 2 and spool 4, the spool right-hand member is provided with circular groove, this circular groove center extends outward outrigger shaft 7, on the outer peripheral surface of outrigger shaft, be provided with annular slot, circular groove, outrigger shaft and annular slot are after shot blast, hot vulcanization rubber or the curing of other soft sealing materials are bonded on this outrigger shaft 7 and have promptly formed seal ring 5, the sealing circle carries out pretension sealing pushing tow by Returnning spring 3, seal ring and valve body 1 internal conical surface are that many lipped joints touch sealing, and present embodiment is lips contact seal.The seal ring pressurized of this structure is little, is difficult for forming permanent deformation, and elastic recovery properties is good simultaneously, is difficult for expanded by heating, prolongs sealing life greatly.Simultaneously be fixed with the bonnet 6 of location protection seal ring 5 at also be threaded fixing or riveting of outrigger shaft 7 ends; this bonnet has outer conical surface; when the bonnet outer conical surface overlaps with the internal conical surface of valve body right-hand member; seal ring 5 spring 3 enforce compression that promptly no longer are reset; so can guarantee effective decrement of seal ring; when spool 4 resetted selfsealings, this bonnet 6 play the guiding role again simultaneously.

Valve body of the present utility model also needs to be connected with a female connector is supporting usually, connects back valve core and is backed down, and medium is promptly negotiable.The assembly process of this union body is, the spool 4 that at first will be set with Returnning spring 3, fixes seal ring 5 and bonnet 6 is put into valve body 1 from left end, draw in behind the leg of multiway elastic component 2 also followed by in the valve body 1 of packing into hand simultaneously, when the multiway elastic component stretches in the valve body, leg utilizes self elastic return original state and by the interior shoulder thrust of valve body 1, this moment, spool 4 promptly can not drop out in valve body.
