Description
Technical field
The utility model relates to a kind of choke valve, relates in particular to a kind of bi-directional movable formula choke valve.
Background technology
In the prior art, heat pump type air conditioner system mainly is made up of compressor, evaporimeter, condenser and throttle part.Throttle part is the critical piece of decision heat pump performance, the minitype air conditioner great majority adopt the capillary module throttling at present, capillary module is made up of two capillaries, a check valve, two screen packs, entire product has a plurality of pads, simultaneously capillary needs a plurality of operations processing such as cutting, coiling, welding, and hidden danger frequently takes place product because the leakage that processing link causes, weldering be stifled etc.On the other hand, capillary is to realize different restriction effects by changing length capillaceous with the aperture, but difference along with air-conditioning system, capillary pipe length, aperture are ever-changing, be unfavorable for the standardization mass production, what capillary adopted simultaneously is the friction Throttle Principle, and the throttling path path length can cause certain energy loss.Because the capillary module copper consumption is big, along with rising steadily of copper valency, Air-conditioning Enterprise is more and more stronger by the demand that cost falls in minimizing air-conditioning copper consumption simultaneously.
Chinese patent 200620103167.1 discloses a kind of bidirectional throttling valve that is used for heat pump type air conditioner, sealing and fixing has the valve seat of two symmetries in the choke valve, wherein be provided with slidably spool in the valve seat slideway, have axial pore on the spool, the spool periphery has three rib pieces, this invention can substitute present capillary module, can be widely used in the air-conditioning system.But this structural requirement valve body is bigger, because the processing technology difficulty causes processing cost than higher, cost advantage is not clearly with respect to capillary module simultaneously.
Chinese patent 200720107950.X discloses a kind of bi-directional secondary choke valve, comprise valve body, an end sealing and fixing has valve seat in the valve body, valve seat comprises opening and slideway, be provided with movable spool in the slideway, have axial aperture on the spool, valve seat is provided with several through flow holes, other end sealing and fixing has fixed spool in the described valve body, and fixed spool has axial aperture.This utility model second throttle valve is a reasonable substitute products of capillary module, but because air-conditioning system ever-changing, this choke valve can only use on some minicomputer specific model, exceeds certain limit and will cause that local noise increases.
Summary of the invention
The utility model provides a kind of bi-directional movable formula choke valve, and it is bigger to have solved existing bidirectional throttling valve volume, the problem of processing difficulties.
A kind of bi-directional movable formula choke valve, the valve body that comprises tubulose, be fixed with two valve seats that are provided with in opposite directions in the valve body, have the opening and the slideway of connection on the valve seat, be provided with movably tape spool in the slideway to the spool of aperture, spool matches with the slideway inner chamber, and slideway has some pod apertures near the sidewall of opening one end, and the body cavity between two valve seats is communicated with slideway by pod apertures.
Preferably, described spool is connected opening with slideway a end cooperates by sphere or conical surface seal, and sealing effectiveness is better
Preferably, described slideway is away from the radially reducing of an end of opening, spool carried out spacing, prevents that spool from deviating from slideway, and easy to process.
Preferably, the two ends that described two valve seats deviate from mutually all are connected with screen pack, can weld between screen pack and the valve seat, also can fuse, and prevent that foreign matter from flowing through, and stop up choke valve.
Preferably, described spool two ends are provided with chamfering, by chamfering guiding fluid, change the noise that causes because of violent sectional area when the minimizing fluid flows through.
The utility model bi-directional movable formula choke valve realizes that by pod apertures the fluid between body cavity and the slideway flows, slideway matches with spool, between the gap especially little, simple in structure, the processing and manufacturing cost is more cheap, helps the miniaturization of spool and valve body simultaneously.

The specific embodiment
As shown in the figure, a kind of bi-directional movable formula choke valve, the valve body 100 that comprises tubulose, be provided with in opposite directions the valve seat 111 and the valve seat 121 that are provided with in the valve body 100, the opening 115 and the slideway 114 that have dead in line on the valve seat 111 and be interconnected are provided with movably tape spool to the spool 112 of aperture 116 in the slideway 114, spool 112 matches with slideway 114 inner chambers, and an end sphere fitted seal that is connected opening 115 with slideway 114 can certainly be that the linear sealing of other shape cooperates, as the conical surface etc.Slideway 114 is away from the radially reducing of an end of opening 115, spool 112 carried out spacing, prevents that it from deviating from.Slideway 114 has pod apertures 117 near an end of through hole 115, has the gap between the slideway end of valve seat 111 and the valve body 100, and the body cavity of valve seat 111 and valve seat 121 is communicated with slideway 114 by pod apertures 117.
Equally, opening 125 that has dead in line on the valve seat 121 and be interconnected and slideway 124, be provided with movably tape spool in the slideway 124 to the spool 122 of aperture 126, spool 122 matches with the inner chamber of slideway 124, an and end sphere fitted seal that is connected opening 125 with slideway 124, slideway 124 carries out spacing away from the radially reducing of an end of opening 125 to spool 122.Slideway 124 has pod apertures 127 near an end of through hole 125, has the gap between the slideway end of valve seat 121 and the valve body 100, and the body cavity of valve seat 111 and valve seat 121 is communicated with slideway 124 by pod apertures 127.
The operation principle of above-mentioned choke valve is as follows:
As shown in Figure 6, when fluid when an end flows into valve body 100, at first pass through screen pack 113 and opening 115, promoting spool 112 moves, stop motion after spool 112 is spacing by the necking end of slideway 114, body cavity between this moment valve seat 121 and the valve seat 111 is communicated with the end of slideway 114 near openings 115 by pod apertures 117, body cavity between fluid direct admission valve seat 121 and the valve seat 111 and fully mixing, at this moment axial aperture 116 not convection cell carry out throttling.
After fluid fully mixes, because the effect of pressure, promoting spool 122 moves to opening 125, its end that is connected opening 125 with slideway 124 is sealed and matched, fluid can only flow out valve seat 121 from axial aperture 126, opening 125 successively, this moment, axial aperture 126 convection cells carried out throttling, by the aperture of axial aperture 126 is set, can accurately control the fluid flow of throttling.
As shown in Figure 7, when fluid when the other end flows into valve body 100, at first pass through screen pack 123 and opening 125, promotion spool 122 deviates from opening 125 and moves, stop motion after spool 122 is spacing by the necking end of slideway 124, body cavity between valve seat 121 and the valve seat 111 is communicated with the end of slideway 124 near openings 125 by pod apertures 127 at this moment, body cavity between fluid direct admission valve seat 121 and the valve seat 111 also fully mixes, this moment axial aperture 126 not convection cell carry out throttling.
After fluid fully mixes, because the effect of pressure, promoting spool 112 moves to opening 115, its end that is connected opening 115 with slideway 114 is sealed and matched, fluid can only flow out valve seat 111 from axial aperture 116, opening 115 successively, this moment, axial aperture 116 convection cells carried out throttling, by the aperture of axial aperture 116 is set, can accurately control the fluid flow of throttling.
When above-mentioned throttle valve applications during,, can realize the refrigeration of air-conditioning and heat by aforesaid two kinds of working methods to air-conditioning system.
