Abstract
The utility model provides a throttle valve, used in a heat pump type air conditioner. The throttle valve is composed of a valve body and a valve core with a throttle channel, and a hush pipe is fixedly arranged on the outside of the valve body. The throttle valve with the hush pipe of the utility model enables the noise of a cavitation generating part during the throttle process of the throttle valve to be reduced.
Description
Technical field
The utility model relates to a kind of choke valve, particularly relates to the choke valve that plays throttling action in the heat pump type air conditioner.
Background technology
The choke valve of existing heat pump air conditioner comprises movable choke valve and fixation type throttle valve.Wherein movable choke valve is referring to Fig. 1; During refrigeration; Refrigerant flows along the direction of arrow, at this moment, heats movable spool 5 and moves up; Open the opening 9 that heats on the valve seat, refrigerant from bottom to top → screen pack 8 → heat valve seat 7 → the heat opening 6 → refrigeration activity spool 4 → refrigeration valve seat 3 → screen pack 2 → outflow choke valve on the valve seat.Referring to Fig. 2; When heating; Refrigerant flows along the direction of arrow, and at this moment, refrigeration activity spool 4 moves down; Open the opening 9 of refrigeration on the valve seat, refrigerant from top to bottom → the movable spool 5 of opening 9 on screen pack 2 → refrigeration valve seat 3 → refrigeration valve seat → heat → heat valve seat 7 → screen pack 8 → outflow choke valve.The choke valve of said structure, in the course of the work, the noise that can produce influences user's use, hinders the popularization of choke valve.Also can produce same problem in the fixation type throttle valve course of work.
Summary of the invention
The utility model provides a kind of choke valve, and it can solve the noise problem that exists in the prior art.
For reaching the purpose that solves the problems of the technologies described above, the technical scheme of the utility model is, a kind of choke valve comprises the valve body of a tubulose spool being arranged in the valve body, has throttling passage on the spool, and valve body is provided with hush pipe outward.During work,, can reduce the noise that part takes place through cavitation erosion in the valve body throttling process refrigerant through the setting of hush pipe.
Preferably, the middle part of said hush pipe is provided with male part, has the sound insulation space between the valve outer surface of male part and correspondence position.The hush pipe of hollow structure strengthens soundproof effect.
Preferably; Said hush pipe covers the corresponding valve body of spool and two exits of throttling spool passage, and extends to the valve body two-port respectively, specifies; When spool is movable, corresponding position when two exits of throttling spool passage refer to spool activity to two extreme position.Like this, during work, hush pipe covers the happening part that cavitates in the throttling process as far as possible, just can better reduce noise.
Preferably, the length of said extension is 3 ~ 5 times of conduit internal diameter.Show that through result of the test noise reduction is obvious and material is relative economizes.
Preferably, said hush pipe is the plastic-aluminum pipe.The use of sandwich, noise reduction is obvious.
Preferably, said hush pipe extends beyond two-port to the valve body two-port respectively, and the hush pipe port is connected with pipeline.Because of hush pipe covers valve body fully, so erasure effect is good.
Optional, the valve body two ends exit enlarging of said tubulose, said hush pipe extends to the reducing place of enlarging to two-port, fixes through valve body port enlarging technology and valve body, simplifies working process.
Optional, the valve body two ends exit reducing of said tubulose, said hush pipe extends to the reducing place of reducing to two-port, fixes through valve body port necking down process and valve body, simplifies working process.
The beneficial effect of the utility model: reduce noise.

The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model clearer; Be example below with the choke valve, the technical scheme of the utility model is described in detail, obviously; Described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment of the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The structural representation of the choke valve that Fig. 3 provides for the utility model embodiment.
As shown in Figure 3, a kind of choke valve comprises the valve body 1 of tubulose being provided with first valve seat 3 and second valve seat 7 that are oppositely arranged in the valve body 1; Have through hole in the middle of first valve seat 3, be provided with first spool, 4, the first spools 4 that movably have throttling passage in the through hole and match with the through hole inner chamber of first valve seat 3; The radially reducing of first valve seat, 3 one ends is carried out spacingly to first spool 4, prevent it and deviate from; The other end was connected with first filter screen 2, prevented that foreign matter from getting into valve body, blocking channel.The body cavity that first valve seat, 3 sidewalls have first-class through hole 9, the first valve seats 3 and second valve seat 7 is communicated with through hole through first-class through hole 9.
Equally, 7 of second valve seats have through hole, are provided with second spool 5 that movably has throttling passage in the through hole; Second spool 5 matches with the through hole inner chamber of second valve seat 7, and the radially reducing of second valve seat, 7 one ends is carried out spacing to second spool 5; Preventing it deviates from; The other end is connected with second screen pack 8, prevents that foreign matter from getting into valve body, blocking channel.The body cavity that second valve seat, 7 sidewalls have second opening, 6, the first valve seats 3 and second valve seat 7 is communicated with through hole through second opening 6.
Second embodiment:
In second embodiment, cancelled being oppositely arranged wherein one group of valve seat, spool and screen pack in the choke valve valve body 1, other internal structures are identical.Hush pipe 10 is isometrical tubular structure, covers the corresponding valve body in spool 4 throttling passage exits, and extends to valve body 1 two-port respectively, until the necking reducer place of valve body 1.
Other embodiments:
Except that adopting first embodiment and the second embodiment hush pipe 10 and valve body 1 coverage mode; Can also take following coverage mode: the two ends of valve body 1 are imported and exported and are not processed; Hush pipe 10 extends beyond valve body 1 port to valve body 1 two-port respectively; When choke valve and the welding of other pipelines, fixing through the temperature fusion that welding produces.
In the utility model in the choke valve operation principle identical with prior art, do not give unnecessary details one by one at this.
Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting the utility model; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection domain of the utility model should be as the criterion with the scope that the utility model claim is defined.
