Abstract
The utility model is a throttling valve used for air conditioner, is composed of a valve body an a valve spool placed inside the cavity. The lower end of the valve spool provides a groove to accept an O-shape ring. A fitting is connected to the bore of the valve body, with a retaining ring and a filter screen placed in the cavity of the fitting. The filter screen is placed on the top of the retaining ring. A through-pipe is fixed on the bore at the lower end of the valve body. The throttling valve can replace a capillary tube structure for convenient flow direction switch-over of the refrigerant during cooling and heating, realizes the functions of a check valve and a filter screen, has simple structure and is convenient to assemble with low cost.
Description
Technical field
The utility model relates to a kind of control valve, is specifically related to the control valve of refrigerant body flow, the flow direction in air-conditioner.
Background technology
Refrigerant body flow generally adopts capillary to regulate in the air-conditioner at present, and is bigger as need refrigerant body flow, then with short capillary, less as need refrigerant body flow, then adopts long capillary, and this just need install some capillaries in air-conditioner.In addition, be to realize refrigeration, refrigerant direction of flow conversion when heating, capillary also must be connected with check valve and filter screen, and the check valve of this capillary pipe structure formula control valve and filter screen be owing to be that branchs is arranged, its complex structure, and cost is high and install difficult.
Summary of the invention
The purpose of this utility model is to solving the problem that prior art exists, provide a kind of simple in structure, can replace capillary pipe structure, two parts of check valve and filter screen can be arranged on a choke valve in the body cavity.
The utility model is achieved in that the spool that is provided with by valve body and inner chamber thereof forms, the lower end of described spool has the groove of placing O shape circle, be connected with joint on the endoporus of described valve body, the inner chamber of described joint is provided with snap ring and filter screen, described filter screen place snap ring above, the lower end endoporus of described valve body is fixed with siphunculus.
One boss can be arranged at the bottom of described spool.
The surface of described spool in axial direction can be provided with fin.
The fin that the surface of described spool in axial direction can be provided with has three.
Described filter screen can be hemispherical.
The utility model is placed O shape circle because the lower end of spool has, be connected with joint on the endoporus of valve body, the inner chamber of joint is provided with snap ring and filter screen, the lower end endoporus of valve body is fixed with siphunculus, and this structure can replace capillary pipe structure, can conveniently freeze, refrigerant direction of flow conversion when heating, and the function of realization check valve and filter screen, simple in structure, easy for installation, cost is low.

Fig. 2 is the status architecture schematic diagram of the utility model when heating;
Fig. 3 is a valve core structure schematic diagram of the present utility model;
Fig. 4 is the vertical view of spool of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail:
The utility model choke valve, the through hole of its valve body 4 is provided with spool 5, and the centre of spool 5 has through hole, and a boss is arranged at the bottom of spool 5, and its surface in axial direction is provided with three fins 8, and spool 5 plays the effect of check valve.The lower end of spool 5 has a groove, and O shape circle 6 is positioned in this groove, plays the effect of sealing.The endoporus of valve body 4 is provided with snap ring 2 and filter screen 3 with the joint 1 that has been threaded, the endoporus of joint 1, filter screen 3 be shaped as hemispherical, refrigerant body and hot media are through filtering out impurity here.Filter screen place snap ring 2 above, the lower end endoporus of valve body 4 is fixed with siphunculus 7, the material of siphunculus is a copper material.
Throttle valve applications is when air-conditioner, and when air-conditioner freezed, the refrigerant body entered the joint inner chamber from nut, through filter screen, spool is dashed to the valve body bottom, the gap of O type circle sealing valve core and valve body, the refrigerant body passes through from the intermediate throughholes of spool, flows out from siphunculus after playing the effect of supercharging again.When air-conditioning heated, then the refrigerant direction of flow was opposite, and the refrigerant body is entered from siphunculus, spool is dashed to joint, the refrigerant body from spool intermediate throughholes and the gap of spool and valve body pass through, through filter screen, from the inner chamber outflow of joint.
Generally speaking, the utility model can replace the adjuster of traditional capillary pipe structure, realizes refrigeration, the conversion of refrigerant direction of flow when heating, and the function of check valve and filter screen is arranged, so the utility model is simple in structure, and easy for installation, cost is low.
