Abstract
The invention discloses a one-way throttling valve with a conveniently-dismountable filter screen and used for an air conditioner. The one-way throttling valve comprises a valve seat and a valve core, wherein the valve seat and the valve core are arranged in a tubular valve body. The one-way throttling valve is characterized in that a U-shaped annular groove is formed in the inlet end of the valve body, and a protective cover capable of rotating in the annular groove and matched with the annular groove in size is arranged at the opening position of the annular groove. A limiting piece folded upwards is arranged at one end of the protective cover. The dense filter screen is arranged in the annular groove and provided with a metal fixing frame, and the metal fixing frame is wrapped in a fluororubber ring. The fluororubber ring is larger than a medium fluid channel in diameter.
Description
Technical field
The present invention relates to choke valve field, specifically a kind of air-conditioner one-way throttle valve with screen pack for convenience detach.
Background technology
In the prior art, the structure composition of air-conditioning mainly contains compressor, condensing unit.Throttle part and evaporimeter composition.Use capillary to be welded on outdoor heat exchanger outlet and high pressure valve place in traditional air conditioner, because the capillary mouth of pipe is very little, and replacing also bothers very much, needs mistress's machine to disassemble, also need after changing capillary again to weld, so the existing choke valve that adopts replaces capillary more.
Choke valve at work, realizes dynamic seal (packing) by refrigerant pressure, and the dynamically hard sealing requirement on machining accuracy of this metal to metal is high, if contain a small amount of impurity in refrigerant and enter fit clearance, then may occur coordinating and lose efficacy, and enhance faster wear speed, reduce the service life of choke valve.
Summary of the invention the present invention aims to provide a kind of air-conditioner one-way throttle valve with screen pack for convenience detach to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of air-conditioner one-way throttle valve with screen pack for convenience detach, comprise valve seat, spool, valve seat, spool are all 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, the opening seat of annular groove is provided with the protecting cover of the same annular groove size adaptation that can rotate in annular groove; Described protecting cover one end is provided with the banking stop upwards turned down; Be provided with fine and closely woven screen pack in described annular groove, screen pack is provided with metal fixed border, and metal fixed border is wrapped in fluorine rubber ring; 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.
Be slidably connected between described annular groove and protecting cover.
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, and screen pack can stop a small amount of impurity contained in refrigerant to enter sealing surface, and reduce wear speed, increases the service life of choke valve.
Two, simultaneously at metal fixed border outer wrapping fluorubber, can sealing function be played, avoid medium to reveal from metal fixed border and valve body gap.
Three, protecting cover mainly plays dustproof effect, can rotate in annular groove, by the position pulling banking stop to control protecting cover.
Four, only need select protecting cover, protecting cover is rotated in groove, then the drag hook on pull-up metal fixed border, just can by screen pack pull-out cleaning, insert in annular groove by screen pack again after having cleaned, structure is simple, and the time of cost is few, economical and practical.

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, comprise 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 the protecting cover 7 of the same annular groove 4 size adaptation that can rotate in annular groove 4, is slidably connected between annular groove and protecting cover.Described protecting cover 7 is the downward U-shaped structure of groove, and protecting cover 7 one end is provided with the banking stop 6 upwards turned down; Be provided with fine and closely woven screen pack 5 in described annular groove 4, screen pack 5 is provided with metal fixed border 8, and metal fixed border 8 is provided with drag hook 10, and metal 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, fluorine rubber ring 9 and annular groove 4 interference fit.
In use for some time, need cleaned filter screen, only need hold banking stop 6, allow protecting cover 7 rotate in annular groove 4, make annular groove become U-shaped opening.Drag hook 10 is caught on, pull-out screen pack 5 with hook.After completing cleaning, then after lubricating fluorine rubber ring 9, then screen pack 5 is inserted in annular groove 4.The present invention cleans easily, and structure is simple, 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 a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
