Description
Technical field
The present invention relates to choke valve field, specifically a kind of air-conditioner one-way throttle with screen pack for convenience detachValve.
Background technology
In the prior art, the structure of air-conditioning composition mainly contains compressor, condensing unit. Throttle part and evaporator bankBecome. In traditional air-conditioning, be to use capillary to be welded on outdoor heat exchanger outlet and high pressure valve place, due to the capillary mouth of pipe veryLittle, also bother very much and change, mistress's machine need to be disassembled, after being changed, capillary also needs again to weld instituteNow to adopt choke valves to replace capillaries more.
Choke valve at work, is realized dynamic seal (packing) by refrigerant pressure, and the dynamically hard sealing of this metal to metal addsWork required precision is high, if contain a small amount of impurity in refrigerant and enter fit clearance, may occur coordinating and lose efficacy, and accelerate millDamage speed, the service life of minimizing choke valve.
Summary of the invention the present invention aim to provide a kind of air-conditioner with screen pack for convenience detach one-way throttle valve withAddress the above problem.
For achieving the above object, technical scheme of the present invention is as follows:
With an air-conditioner one-way throttle valve for screen pack for convenience detach, comprise valve seat, spool, valve seat, spool are equalBe arranged in the valve body of tubulose, it is characterized in that: the entrance point of described valve body is provided with a U-shaped annular groove, establish at the opening seat of annular grooveBe equipped with the adaptive protecting cover of same annular groove size that can rotate in annular groove; Described protecting cover one end is provided with the upwards banking stop of turnover;In described annular groove, be provided with fine and closely woven screen pack, screen pack is provided with metal fixed border, and metal fixed border is wrapped in fluorubberIn circle; The diameter of described fluorine rubber ring is greater than the diameter of medium fluid passage.
Described protecting cover is the downward U-shaped structure of groove.
Between described annular groove and protecting cover, be slidably connected.
Described metal fixed border is provided with drag hook.
Described fluorine rubber ring and annular groove interference fit.
One, beneficial effect of the present invention is: in medium fluid passage, be provided with screen pack, screen pack can stop coldThe a small amount of impurity containing in matchmaker enters sealing surface, the speed that reduces wear, the service life of increase choke valve.
Two, simultaneously at metal fixed border outer wrapping fluorubber, can play sealing function, avoid medium from metal fixed edgeIn frame and valve body gap, reveal.
Three, protecting cover mainly plays dustproof effect, can in annular groove, rotate, can be by pulling the position of banking stop control protecting coverPut.
Four, only need to select protecting cover, protecting cover is rotated in groove, then drag hook on pull-up metal fixed border, just can be by mistakeFilter screen pull-out is cleaned, and after having cleaned, screen pack is inserted in annular groove again, and simple in structure, the time of cost is few, economical and practical.
Brief description of the drawings
Fig. 1 is the one-way throttle valve structural representation of the air-conditioner with screen pack for convenience detach provided by the invention.
Fig. 2 is protecting cover schematic diagram provided by the invention.
Fig. 3 is filter screen structure schematic diagram provided by the invention.
Mark in figure: 1 be valve seat, 2 for valve body, 3 for spool, 4 for annular groove, 5 for screen pack, 6 for banking stop, 7 for protecting cover,8 is that metal fixed border, 9 is that fluorine rubber ring, 10 is drag hook.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of air-conditioner one-way throttle valve with screen pack for convenience detach, comprises valve seat 1, spool 3,Valve seat 1, spool 3 are all arranged in the valve body 2 of tubulose, it is characterized in that: the entrance point of described valve body 2 is provided with a U-shaped annular groove 4,The opening seat of annular groove 4 is provided with and can, at the adaptive protecting cover 7 of the same annular groove of annular groove 4 interior rotations 4 size, between annular groove and protecting cover, slidesBe dynamically connected. Described protecting cover 7 is the downward U-shaped structure of groove, and protecting cover 7 one end are provided with the upwards banking stop 6 of turnover; Described annular grooveIn 4, be provided with fine and closely woven screen pack 5, screen pack 5 is provided with metal fixed border 8, and metal fixed border 8 is provided with drag hook 10, goldBelonging to fixed border 8 is wrapped in fluorine rubber ring 9; The diameter of described fluorine rubber ring 9 is greater than the diameter of medium fluid passage, fluorubberCircle 9 and annular groove 4 interference fit.
In use for some time, need cleaning and filtering net, only need to hold banking stop 6, allow protecting cover 7 in the interior rotation of annular groove 4,Make annular groove become U-shaped opening. Catch on drag hook 10 with hook, pull-out screen pack 5. Complete after cleaning, then after lubricated fluorine rubber ring 9, thenScreen pack 5 is inserted in annular groove 4. The present invention cleans easily, simple in structure, and does not affect the sealing effectiveness of valve body.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this areaArt personnel, the present invention can have various modifications and variations. Within the spirit and principles in the present invention all, to do any repairingProtection scope of the present invention changes, be equal to replacement, improvement etc., within all should be included in.
