Abstract
The utility model discloses a throttling short pipe for an air conditioner, which comprises a valve body; a hollow cavity arranged on the valve body is internally provided with a valve seat fixedly connected with the valve body; a hollow cavity arranged on the valve seat is internally provided with a heating valve core and a refrigerating valve core which are fixedly connected with the valve seat, and a check ring used for limiting the sliding range of the heating valve core and the refrigerating valve core; and the heating valve core and the refrigerating valve core are provided with through holes along the axial direction of the valve body. The throttling short pipe has the advantages of simple structure, less material consumption, fewer welding spots and high production efficiency.
Description
Technical field
The utility model belongs to air-conditioner throttling technology field, particularly relates to a kind of idle call restriction sleeve.
Background technology
At present, traditional air-conditioning comprises that the window machine all is to use capillary to come throttling, and processing technology capillaceous has unstability, opens material such as the two ends capillaceous mouth of pipe and adds easy reducing distortion in man-hour, thereby influence the stability of flow system.Capillary-compensated also wants a lot of elements (the capillary sleeve pipe, air conditioner also has check valve etc. for filter, transition conduit) to cooperate, thereby need expend a large amount of copper products, and it is many and cumbersome that the buying worker adds preface.Need a lot of related personnel's of a plurality of departments cooperation.Respectively those single parts are bought, the personnel by the heat exchange workshop open material, assembling, welding, leak detection etc. again, become an assembly through after a series of operation.As seen material cost, human cost and the time cost that spends in this process has much.Capillary module also has a shortcoming to be exactly: it is welded together by a plurality of single part assemblings, and many generation easily of solder joint stopped up or leakage phenomenon, is unfavorable for reliability service.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of idle call restriction sleeve of saving cost and saving the space.
For solving the problems of the technologies described above, technical scheme of the present utility model is: a kind of idle call restriction sleeve, comprise valve body, be provided with the valve seat that is connected with valve body in the set hollow cavity of valve body, be provided with in the set hollow cavity of valve seat with valve seat is connected and heat spool and refrigeration spool, and be provided with the back-up ring that heats spool and refrigeration spool sliding scale, heat spool and refrigeration spool are axially arranged with perforation along valve body through hole.
Further, the both sides of valve seat are respectively equipped with filter screen.
Further, back-up ring is installed in and heats between spool and the refrigeration spool.
Further, valve body is connected by the concave-convex interface arrangment with valve seat.
Further, filter screen is trapezoidal along the axial cross section of valve body.
Further, valve body one end is connected with condensator outlet, and the other end links to each other with evaporator.
Advantage of the present invention is:
(1) biggest advantage of the present invention is the cost of saving material cost, human cost and time cost, installs after only needing to purchase suitable restriction sleeve in air-conditioning production to get final product.
(2) solder joint of the present invention is few, is not easy to take place to stop up or leak, and helps the reliability operation.
Description of drawings
Fig. 1 is the structural representation of this practical restriction sleeve.
Its body embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention includes valve body 1, be provided with the valve seat 2 that is connected with valve body 1 in the set hollow cavity 8 of valve body 1, be provided with in the set hollow cavity 9 of valve seat 2 with valve seat 2 is connected and heat spool 3 and refrigeration spool 5, and be provided with the back-up ring 4 that heats spool 3 and refrigeration spool 5 sliding scales, heat spool 3 and refrigeration spool 5 are axially arranged with perforation along valve body 1 through hole 7.
The both sides of valve seat 2 are respectively equipped with filter screen 6, and back-up ring 4 is installed in and heats between spool 3 and the refrigeration spool 5, and valve body 1 is connected by the concave-convex interface arrangment with valve seat 2, and filter screen 6 is trapezoidal along the axial cross section of valve body 1.
During refrigeration, after the cooling with fixed attention of the overheated cold media gas process of the HTHP of compressor discharge condenser, left end by Fig. 1 enters, the spool 3 that heats of left end is opened, the refrigeration spool of right-hand member and valve seat 2 closures (2 one-tenth air-tight states of refrigeration spool 5 and valve seat), force refrigerant in the through hole 7 of refrigeration spool 5, to flow through, reach the required flow of refrigeration by the refrigeration spool 5 of selecting different through-hole aperture sizes, the throttling decrease temperature and pressure becomes the gas-liquid mixture (having flash gas to produce) of low-temp low-pressure, enter evaporimeter heat absorption evaporation, sucked back by compressor, thereby form refrigerating circuit.When heating, then change the flow direction of refrigerant by the cross valve parts, the refrigerant that comes out from indoor heat exchanger is entered by the right-hand member by Fig. 1, the refrigeration spool 5 of right-hand member is opened, left end heat spool 3 and valve seat 2 closures (heating 2 one-tenth air-tight states of spool 3 and valve seat), force refrigerant in the through hole 7 that heats spool 3, to flow through, inlet chamber external heat exchanger heat absorption evaporation, sucked back by compressor, heat the loop thereby form.
The application of restriction sleeve on the window machine is exactly to have replaced capillary module, and heating spool 3 is exactly restricting element with refrigeration spool 5, is equivalent to the capillary in the capillary module; Filter screen 6 is exactly to be equivalent to filter.Exhaust outlet of compressor links to each other with condenser inlet, and the compressor air suction mouth links to each other with evaporator outlet, and an end and the condensator outlet of valve body 1 join, and the other end links to each other with evaporator.Form a closed refrigerating circuit.Restriction sleeve applies in the window machine, and its effect is the same with capillary, all is by the refrigerant flow of high-pressure side condensator outlet to the low-pressure side evaporator inlet in the control system.
