Two, technical scheme
For solving the problems of the technologies described above; The utility model provides a kind of bi-directional movable formula choke valve, include in the valve body, valve body of tubulose and be provided with two independently valve seat and screen packs, in the valve seat all and slideway; Be equipped with the opening and the slideway of connection in the slideway; Be equipped with movably spool in the slideway with throttle orifice, wherein, above-mentioned spool and slideway inner chamber matched in clearance; Above-mentioned slideway is provided with some pod apertures near the sidewall of opening one end, leaves the gap that is communicated with pod apertures between the valve seat at above-mentioned slideway place and the valve interior wall.
As optimization, above-mentioned spool is connected opening with slideway a end cooperates through conical surface seal.
As optimization, above-mentioned slideway carries out spacing away from the radially reducing of an end of opening to spool.
As optimization, above-mentioned spool is square, and two ends all are provided with chamfering.
Three, the beneficial effect of the utility model
The utility model bi-directional movable formula choke valve spool adopts cubic rounding to handle, the more round material-saving of material, and it is lighter to conduct oneself with dignity, easy to process in addition; Do not need turning, and the precision die moulding, smooth in appearance; Be not easy to intercept in valve seat inside, contact area is little, under corresponding refrigerant effect; Quicken the refrigerant flow efficiency, shortened the reaction time, improved energy-saving effect.

Among the figure, 1 is valve body, and 2 is first valve seat, and 3 is second valve seat, and 4 is screen pack, and 5 is screen pack, and 6 is opening, and 7 is opening, and 8 is slideway, and 9 is slideway, and 10 is spool, and 11 is spool, and 12 is pod apertures, and 13 is pod apertures, and 14 is throttle orifice, and 15 is throttle orifice.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model bi-directional movable formula choke valve is described in further detail.Following examples are used to explain the utility model bi-directional movable formula choke valve, but are not used for limiting the scope of the utility model.
Embodiment: shown in Fig. 1 to 3; The utility model bi-directional movable formula choke valve; Include and be provided with identical valve seats (first valve seat 2 and second valve seat 3) of two independence and identical screen pack (screen pack 4 and screen pack 5) in the valve body 1, valve body of tubulose; Valve seat (is equipped with the identical opening (opening 6 and opening 7) of connection and identical slideway (slideway 8 and slideway 9) in first valve seat 2 and second valve seat 3; Be equipped with the spool (spool 10 and spool 11) of the different throttle orifices of movably identical band (throttle orifice 14 and throttle orifice 15) in the slideway (slideway 8 and slideway 9); Wherein, Above-mentioned spool (spool 10 and spool 11) and slideway (slideway 8 and slideway 9) inner chamber matched in clearance; Above-mentioned slideway (slideway 8 and slideway 9) is provided with some identical pod apertures (pod apertures 12 and pod apertures 13) near the sidewall of opening (opening 6 and opening a 7) end, leaves the gap that is communicated with pod apertures (pod apertures 12 and pod apertures 13) between the valve seat (first valve seat 2 and second valve seat 3) at above-mentioned slideway (slideway 8 and slideway 9) place and valve body 1 inwall.
Above-mentioned bi-directional movable formula choke valve when refrigerant is got into by the A end, through screen pack 4, filters out impurity in the air-conditioning work process; After refrigerant fully mixes, because the effect of pressure promotes spool 10 to moving away from opening 6; Its end that is connected pod apertures 12 with slideway 8 is opened, and refrigerant intelligence flows out from the pod apertures 12 of valve seat successively, because pod apertures 12 is bigger than throttle orifice 14; Refrigerant flows out from throttle orifice 14 hardly under pressure, and refrigerant flows out first valve seat 2, get into second valve seat 3 after; Because the pressure effect promotes spool 11 with opening 7 sealings, pod apertures 13 is closed; Can only flow into the opening 7 from throttle orifice 15, see through screen pack again and flow out, play throttling action; When refrigerant was got into by the B end, its process and A → B were opposite.Above-mentioned pod apertures (pod apertures 12 and pod apertures 13) is bigger than throttle orifice (throttle orifice 14 and throttle orifice 15).
Above-mentioned bi-directional movable formula choke valve is A → B and all throttlings of B → A in the course of the work, but throttling varies in size.In the process of whole A → B and B → A,, reach predetermined flow, and form the wherein loop that heats or freeze, play throttling action through selecting the spool of different orifice sizes.
Above-mentioned spool (spool 10 and spool 11) is square, and two ends all are provided with chamfering.Use this bi-directional movable formula choke valve, its spool (spool 10 and spool 11) more round material-saving of raw material, it is lighter to conduct oneself with dignity, easy to process in addition; Do not need turning, and the precision die moulding, smooth in appearance; Be not easy to intercept in valve seat (first valve seat 2 and second valve seat 3) inside, contact area is little, under corresponding refrigerant effect; Quicken the refrigerant flow efficiency, shortened the reaction time, improved energy-saving effect.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
