Abstract
The utility model relates to a filter type check throttle valve used in a heat pump air conditioner, composed of a casing body, a capillary tube welded on the casing body, a valve body arranged in the casing body, a limiting rod, a filter screen, etc. A valve core is provided with pyramidal stainless steel or a nylon triangular prism at the front end to increase the flow area of the medium to improve the fluidity of the medium of the air-conditioner, the cup shape filter screen is used for preventing the system for being blocked, and a double fixing groove is fixed between the filter screen and the casing body to increase the reliability of the product.
Description
The utility model relates to a kind of heat pump type air conditioner filtering type one-way throttle valve, belongs to a kind of device that is used for regulating automatically heat pump type air conditioner medium circulatory system throttling performance.
The refrigeration and the heating operation of heat pump type air conditioner realize that by four-way change-over valve it is different with heating operation status parameter separately to freeze, and requires the rate-of flow difference in the system, thereby adopt the filtering type one-way throttle valve can satisfy this requirement.
The heat pump type air conditioner of existing structure is formed by housing, the housing that is built-in with valve body, throttle capillary tube and two pure copper tube assembly weldings with the filtering type one-way throttle valve, described valve body is made by brass, in have of processing to be the spool of cone by the stainless steel square rod, when the cone of spool front end contacts the valve body taper hole, this valve body is in cut-off state, otherwise then is in opening state.This valve body is a straight-through type, and its import, outlet end are welded with a pure copper tube respectively, and the throttle capillary tube two ends are welded in the valve body both sides respectively and are communicated with medium channel, and when described spool contacted the valve body taper hole, medium throttling from throttle capillary tube was passed through.Also dispose filter element-filter screen in the filtering type one-way throttle valve of existing structure, its effect mainly is owing to inevitable small amount of impurities in compressor, air conditioner manufacturing and the installation process in the filter medium.The deficiency of existing structure is: 1, filter screen is plane or spherical shape, and its flow area is less relatively, easily stops up; 2, the spool that processes by square rod of body cavity, its cross section is a square, this spool is relative less with the space between the body cavity wall, has hindered the circulation of medium when heat pump type air conditioner freezes, and has reduced refrigeration; 3, adopt single fixed groove to fix poor reliability between filter screen and housing.
The utility model aims to provide the better filtering type one-way throttle valve of a kind of performance.
The utility model achieves the above object by taking following measure: 1, spool adopts the tri-prism of the cone of the less relatively and front end processing of cross-section area, thereby has increased the gap between spool and body cavity wall; 2, filter screen adopts the bigger cup-shaped filter screen of surface area, and difficult quilt stops up fully; 3, adopt two fixed grooves to fix between filter screen and housing, increased reliability.
Concrete technical solution is as follows:
The utility model is welded by housing that is built-in with filter screen and valve body and capillary tube, valve body is built-in with spool, described capillary tube is welded in the valve body both sides, and interlinks with the medium channel at valve body two ends, and it is characterized in that: described spool is the tri-prism that front end is processed as cone.
Further technical solution is:
Filter screen in the above-mentioned filtering type one-way throttle valve is the bigger cup-shaped filter screen of surface area.
In addition, on the above-mentioned housing corresponding to filter screen opening end position the twice fixed groove is arranged, described housing is fixed in filter screen in it by this twice fixed groove.
The utlity model has following advantage: 1, this spool is owing to adopt triangle, and its flow area increases, and has improved the air conditioner air flowability, can reach good refrigeration; 2, filter screen has increased effective flow area, makes that the heat pump type air conditioner circulatory system is difficult for stopping up; 3, adopt two fixed grooves to fix between filter screen and housing, increased reliability.
Below with reference to drawings and Examples the utility model is further described.
Accompanying drawing 1 is the utility model embodiment's a structural representation.
Referring to accompanying drawing.This embodiment comprises housing 1.1, place interior valve body 1.6 filter screens 1.2 of housing and capillary tube 1.3 etc., wherein, valve body 1.6 is made by brass, spool 1.5 is housed in the valve pocket, this spool is the stainless steel tri-prism that front end is processed as cone, also has a limited post 1.4 to prevent deviating from of spool in the rear end of housing inner spool 1.5, side at housing 1.1 inner valve bodies has a cup-shaped filter screen 1.2, it is fixedlyed connected by the twice locating slot on it with housing, throttle capillary tube 1.3 is a pure copper tube, its two ends are welded in the housing 1.1 of valve body both sides respectively, and connect the medium channel of valve body both sides respectively.When the filtering type one-way valve was worked, the cone of spool was blocked on the taper hole of valve body, and valve body is in cut-off state, and medium can only pass through from throttle capillary tube 1.3 throttlings.
Claims (3)
1, a kind of heat pump type air conditioner filtering type one-way throttle valve, be welded by housing that is built-in with filter screen and valve body and capillary tube, valve body is built-in with spool, described capillary tube is welded in the valve body both sides, and interlink with the medium channel at valve body two ends, it is characterized in that: described spool is the tri-prism that front end is processed as cone.
2, filtering type one-way throttle valve according to claim 1 is characterized in that: described filter screen is the bigger cup-shaped filter screen of surface area.
3, according to claim 1 or 2 arbitrary described filtering type one-way throttle valves, it is characterized in that: on the described housing corresponding to filter screen opening end position the twice fixed groove is arranged, described housing is fixed in filter screen in it by this twice fixed groove.
