Abstract
The utility model discloses a protecting shield for self-sealing valves, which comprises a cap-shaped casing, and the opening portion of the inner cavity of the casing is provided with an annular protrusion which can be sleeved on the self-sealing valve. An annular stage which is arranged inside the inner cavity of the casing is capable of abutting against the outer casing of the self-sealing valve so as to be limited, thereby enabling a space to be reserved between a top rod of the valve core of the self-sealing valve and the inner wall of the casing. The protecting valve can prevent the opening of the self-sealing valve and gas leakage caused by collision or extrusion of the top rod of the valve core of the self-sealing valve. The protecting valve has the advantages of being simple in structure, convenient in assembly, difficult to drop, good in protecting effect and low in cost.
Description
Technical field
The utility model relates to the air conditioner parts field, relates in particular to the protective housing of the self-styled valve that uses on a kind of air-conditioning.
Background technique
Publication number is that the patent documentation of CN200982414Y discloses a kind of valve that is used for A/C evaporator, comprise shell and be located at its interior spool, also be provided with spring in the shell, described shell middle part is provided with internal projection, one end of spring is positioned to be located on the interior spring stop collar of shell one end, the other end of spring is limited in internal projection, be arranged with the spool that an end is an arc convex in the spring, the spool the other end is sheathed in the endoporus of spring stop collar, and spool is fixedlyed connected with the spring stop collar, is provided with the rubber stopper that is sealed and matched with arc convex in a side of internal projection.This self-styled valve is used for air conditioner in the inflation selfsealings of manufacture process to the sealability test of refrigerant pipe.Because the spool of this self-styled valve in the manufacturing of air conditioner, to transport and deposit in the process be outside being exposed to all the time, so easily caused self-styled opening of valves, gas leakage because of the spool of self-styled valve collides or pushes, thus the quality that influence air conditioner with install and use.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of protective housing of self-styled valve, can avoid the spool push rod of self-styled valve to be collided or push and cause self-styled opening of valves, gas leakage, have simple in structure, ease of assembly, difficult drop-off, good, the low cost and other advantages of protection effect.
To achieve the above object, the utility model has adopted following technological scheme:
A kind of protective housing of self-styled valve, it is characterized in that, the housing that comprises hat, the opening of described housing inner chamber is provided with one can overlap the annular protrusion that is buckled on the self-styled valve, thus described housing inner chamber inside have one can and the shell of self-styled valve offset and retain the ring-shaped step in gap between the inwall of spacing spool push rod that makes self-styled valve and described housing.
The utility model is owing to adopted above technological scheme, the housing of hat is enclosed within on the self-styled valve, the annular protrusion of housing inner chamber (annular protrusion can be continuous projection ringwise, also can be a plurality of alternate annulars of strip projected parts formation spaced apart) overlap to be buckled in and can avoid protective housing to come off on the self-styled valve in the corresponding annular groove, the interior step of housing inner chamber then with the shell of self-styled valve (housing parts around the spool push rod) thus the spacing spool push rod of self-styled valve that makes that offsets is avoided the inner walls extruding of external force and protective housing, can avoid manufacturing at air conditioner, transportation and deposit in the process because of self-styled valve core push rod is collided or pushes and cause self-styled opening of valves, gas leakage, simultaneously also can avoid dust to enter spool pollutes self-styled valve inner structure, has simple in structure, ease of assembly, difficult drop-off, protection effect is good, low cost and other advantages.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
The protective housing of a kind of self-styled valve as shown in Figure 1, the housing 1 that comprises hat, the opening of described housing 1 inner chamber is provided with one can overlap the annular protrusion 11 that is buckled on the self-styled valve, thus described housing 1 inner chamber inside have one can and the shell of self-styled valve offset and retain the ring-shaped step 12 in gap between the inwall of spacing spool push rod that makes self-styled valve and described housing 1.
