Abstract
The invention relates to a one-way valve of an air conditioner. The one-way valve comprises a tubular valve body, and a valve base provided with a valve element; a flow-guide is formed in the valve base; a groove is formed in the tail end of the valve base, and a retainer ring is fixedly arranged therein; and the valve element can be limited to move by the retainer ring during moving. The one-way valve is reasonable in structural design, few in parts and convenient for machining, reduces the collision between the valve element and a stop pin, and effectively enhances the use performance.
Description
Technical field
The present invention relates to a kind of check valve, particularly relate to a kind of air-conditioning check valve。
Background technology
Check valve is a kind of valve limiting fluid one way flow。When on the liquid pipe being arranged on hot Pump air conditioner, then can preventing the opposite direction flowing when system cold-producing medium when heating or kind of refrigeration cycle changes, the high-low pressure difference fully regulate refrigeration, heating, balance freezes, capillary pressuring difference when heating。
Existing check valve, rustless steel valve core check valve mainly has two kinds, and one is: the check valve of breather plug location, and two is adopt backing pin, the check valve of location。The former has the drawback that parts are many, processing difficulties, and cost is high；The latter has the drawback that when system is run, and spool can constantly clash into the internal continuous collision producing sharp-pointed metal bump sound, spool and backing pin of valve seat along with liquid stream, can come off, thus affecting the use of check valve after time length from valve body。
Summary of the invention
Present invention aim to address the problems referred to above, it is provided that a kind of air-conditioning rustless steel valve core check valve。
The technical scheme realizing the object of the invention is: a kind of air-conditioning check valve, including tubular valve body, equipped with the valve seat of spool, described valve seat offering conduction hole, the end of described valve seat has groove, baffle ring it is fixed with inside it, can by baffle ring restriction motion when spool moves。
Above-mentioned air-conditioning check valve, described baffle ring is provided with central through hole。
After adopting technique scheme, the present invention has following positive effect:
(1) present invention, designs rational in infrastructure；(2) decrease the collision of spool and backing pin, effectively enhance the serviceability of check valve；(3) part is few, easy to process。
Accompanying drawing explanation
Being clearly understood to make present disclosure be easier to, below according to specific embodiment and in conjunction with accompanying drawing, the present invention is further detailed explanation, wherein
Fig. 1 is present configuration schematic diagram。
In figure, each label represents:
1, spool；2, valve seat；3, valve body；4, conduction hole；5, groove；6, baffle ring；7, central through hole；8, valve port。
Detailed description of the invention
(embodiment 1)
Air-conditioning check valve of the present invention, including tubular valve body 3, equipped with the valve seat 2 of spool 1, valve seat 2 offers conduction hole 4, the end of described valve seat 2 has a groove 5, inlaying inside it and be fixed with baffle ring 6, can be limited motion by baffle ring 6 when spool 1 moves, baffle ring 6 is provided with central through hole 7。Air-conditioning refrigerant enters from one end of check valve, spool 1 moves toward the other end of valve seat 2 after being subject to the thrust of cold-producing medium, being blocked by the baffle ring 6 on valve seat 2 and no longer move, now cold-producing medium flows from the conduction hole 4 valve seat 2 and flows out check valve from the other end of check valve after valve seat 2 outer wall。When air-conditioning refrigerant enters from opposite direction, spool 1 following current is shifted onto valve port 8 place of valve seat 2 by air-conditioning refrigerant, and spool 1 limits valve port 8 and forms sealing state, reaches the effect of check valve backward stop。
Particular embodiments described above; the purpose of the present invention, technical scheme and beneficial effect have been further described; it is it should be understood that; the foregoing is only specific embodiments of the invention; it is not limited to the present invention; all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention。
Claims (2)
1. an air-conditioning check valve, including tubular valve body (3), equipped with the valve seat (2) of spool (1), described valve seat (2) offers conduction hole (4), it is characterized in that: the end of described valve seat (2) has groove (5), baffle ring (6) it is fixed with inside it, can by baffle ring (6) restriction motion when spool (1) is mobile。
2. air-conditioning check valve according to claim 1, it is characterised in that: described baffle ring (6) is provided with central through hole (7)。
