Abstract

A kind of accurate gas charging valve, belongs to the technical field of mechanical structure, comprises valve body and interior valve inside located therein, valve core retainer plate, seal ring; It is characterized in that: be provided with limited impression in described valve body one end open, in valve body, middle part is provided with positioning boss, is provided with a through hole, is provided with matching thread in valve body the other end opening in the middle of boss, and in valve body, nearly matching thread end is provided with positive stop lug boss; After the heating of valve core retainer plate, compress and be implanted in valve body, be limited in boss in the middle part of valve body; Valve inside is connected fitted seal with valve core retainer plate by screw threads for fastening; On the positive stop lug boss of seal ring and valve body interference fit nearly threaded end in valve body.It is simple, firm that the utility model has structure, and tightness is good, steady quality, cost performance high.

Description

Accurate gas charging valve

Technical field

The utility model relates to a kind of accurate gas charging valve being applicable to household electric appliances.

Background technique

In household electric appliances manufacture process, in the manufacture process of particularly air conditioner, heat exchanging vaporizer has to pass through air tight test, judges whether heat exchanging evaporator exists the safe mass problem of leakage.Traditional manufacturing process is: the supplying tube of vaporizer welds a pipe joint, with diameter 6mm, length 80mm copper pipe, horn mouth in 90 ° is expanded in one end, put a copper nut matched with pipe joint, the horn mouth of copper pipe one end and the cone match of pipe joint end face seal, and are connected with pipe joint locking with copper nut, then, the copper pipe the other end connects rapid pipe joint inflation, with the sealing of pliers folder flat copper pipe, then seals with gas welding.This manufacture technics cost is high, sealing is unstable.The patent No. is that the Chinese utility model patent of ZL 200620109037.9 discloses a kind of valve, and it solves above-mentioned tratitional technology problem substantially.But along with air conditioner workmanship standard will improve, a batch quality for its product hermeticity fails to reach actual requirement completely, meanwhile, its internal structure part is many, and efficiency of assembling is low, and scale cost is higher.

Summary of the invention

The purpose of this utility model proposes a kind of accurate gas charging valve being applicable to household electric appliances, solves at present technically Problems existing, meets the current demand of household electric appliances increased quality and cost reduction.

Above-mentioned technical purpose of the present utility model realizes by following technological scheme:

A kind of accurate gas charging valve being applicable to household electric appliances, comprise valve body and establish valve inside in the inner, valve core retainer plate and seal ring is also provided with in valve body, it is characterized in that: in described valve body, in one end open, be provided with matching thread, in valve body, nearly matching thread end establishes seal ring positive stop lug boss, in valve body, middle part is provided with valve core retainer plate positive stop lug boss, is provided with valve core retainer plate position probing groove in the valve body the other end; Valve core retainer plate, by after heating, compresses and implants in valve body, is limited in middle part boss in valve body; Seal ring and valve body interference fit closely have on the boss of matching thread one end in valve body, and valve inside is connected by screw threads for fastening with valve core retainer plate.

Matching thread in valve core retainer plate is connected with the matching thread secure fit on valve inside, and the cooperation conical surface of valve inside coordinates conical surface press seal with valve core retainer plate, and valve inside self has remarkable one-way conduction and air-tightness.

As preferably, described seal ring and valve inside are all the accurate parts and components of standard of industry universal, have good tightness.

It is simple, reliable that the utility model has structure, and steady quality, tightness is good, cost performance high.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described

Embodiment 1: as shown in Fig. 2,3,4,5, and valve core retainer plate 2 is arranged on the detecting groove 3-3 lower end in valve body 3, is limited in valve body 3 inner convex platform 3-2, can judge whether valve core retainer plate 2 is seated by detecting groove 3-3 in valve body 3; Valve inside 1 is locked by valve inside 1 screw thread 1-10 and valve core retainer plate 2 screw thread 2-2 and is connected; The conical surface 1-3 of valve inside 1 and the conical surface 2-1 fitted seal of valve core retainer plate 2; Seal ring 4 and valve body 3 interference fit are on boss 3-1.

Actual when using, the pipe joint in the cooperation internal thread 3-6 in valve body 3 open at one end and the household electric appliances product that matches with it locks, and the conical surface of pipe joint front end and seal ring 4 compression fit seal simultaneously; Other one end of valve body 3 is inserted in inflating fast joint, snap ring in inflating fast joint blocks on valve body 3 outer lug boss 3-5 and is fastenedly connected, thimble in inflating fast joint backs down the valve core bar 1-6 of valve inside 1, and at this moment accurate gas charging valve is on state, completes inflation.
