Abstract
The utility model discloses a one-way valve for hot-pump air conditioner.The one-way valve comprises a valve body in which a valve carrier sealed and fixed; the valve carrier comprises a valve hole and a slideway, the valve hole communicated with the slideway in which a slideable core is arranged; a plurality of slots are arranged in the external wall of the valve carrier and valve hole end and a plurality of prismatic pieces are embedded in the slots and arranged in the corresponding position of the valve body; three prismatic blocks surrounded the valve core and a spherical chamfer angle equipped at the anterior part of the valve core. Compared with the prior art, the utility model has a good sealing property between the valve body and the valve carrier, a good compatibility of the valve carrier and valve core, a reasonable structure of the exhaust and drainage, low noise when conducting, reliable performance, long life span and wide application in air conditioning system.
Description
Technical field
The utility model relates to a kind of check valve, refers in particular to a kind of check valve that is used for heat pump type air conditioner.
Background technology
Check valve is that a kind of limit fluid folk prescription is to the device that flows.When on the liquid pipe that is installed in the heat pump type air conditioner machine, then can prevent when system at the reverse flow that heats cold-producing medium when changing, the high-low pressure difference that fully adjust refrigeration, heats, balance refrigeration, the capillary pressuring difference when heating with kind of refrigeration cycle.When and for example being installed on the blast pipe of compressor, then can prevent when compressor high temperature return-air out of service flow back to the low temperature storehouse or after compressor is out of service cold-producing medium condense in air intake duct.
Existing check valve by its structure difference, mainly contains two types: a kind of is to adopt stainless steel ball and brass mounted to be sealed and matched, and the shortcoming of this structure is that the invar ball exists the spheroid foozle, and circularity does not reach requirement, influences sealing property thus.On the other hand, steel ball can produce rolling when work, and noise is big.Another kind is to adopt the spool and the brass valve seat of polytetrafluoroethylmaterial material processing to be sealed and matched, match with taper hole in the valve seat by the circular cone of spool head, the shortcoming of this structure has: the one, because of the mismachining tolerance of two conical surfaces, sealing is poor, the 2nd, because of the spool body big, and directly in valve body, move, afterbody is only stopped mutually by the contract valve interior wall of item or the pin that is positioned in the valve body, makes the fuse guiding unstable; The 3rd, for the discharge opeing exhaust is provided,, influenced overall sealing performance and intensity at spool body fluting.
Utility model patent 97214828.0 discloses a kind of air conditioner check valve, by the valve seat in valve body, the valve body, the spool that cooperates with valve seat is formed, spool is that conical head and columniform body are formed, conical spool head matches with the valve opening of valve seat, in the valve seat wall, have outside passage and the valve seat exhaust duct is arranged, the slideway that provides spool to move is arranged in valve seat, be equipped with the spool blocking mechanism in the valve body.This technical scheme poor sealing, performance is not good.
Summary of the invention
A kind of valve body is provided the utility model and valve base sealing is good, valve seat and the spool matching property is good, the discharge opeing exhaust structure rationally, the little check valve of noise during conducting.
A kind of check valve that is used for heat pump air conditioner comprises valve body, and sealing and fixing has valve seat in the valve body, valve seat is made up of valve opening and slideway, and valve opening is communicated with slideway, is provided with slidably spool in the slideway, described spool is that periphery has three rib pieces, and the spool head has the sphere chamfering.
Described valve seat valve opening end and valve body are fixed, and valve opening end outer wall is provided with several grooves, and the corresponding position is provided with the rib sheet in some embedding grooves on the valve body.
Described slideway and valve opening opposite end are provided with back-up ring.
Described valve seat slideway two walls are provided with several incremental holes.
Spool of the present utility model adopts the triangular profile, effectively alleviated the spool deadweight, in the process of in slideway, sliding, wearing and tearing have been reduced with valve base inner wall, in the moment of spool closure, effectively reduced impulsive force, thereby increased service life the potted line of spool sphere chamfering and slide ramp cooperation formation; Spool can be free to slide in slideway, and the spool head is designed to the sphere chamfering, and better tightness between the valve seat, and the end that the valve seat slideway is relative with valve opening is provided with fixedly back-up ring, can be used for controlling spool stroke; Valve seat and valve body adopt rib sheet and groove to be fixed, and have effectively increased the rigidity of whole valve member; Have additional several incremental holes on valve seat slideway two walls, between valve seat and valve interior wall, form incremental passage, effectively increased reverse through-current capacity, reduced noise.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is an A part enlarged diagram among Fig. 1.
The specific embodiment
Show that as Fig. 1,2 a kind of check valve that is used for heat pump air conditioner comprises valve body 1, sealing and fixing has valve seat 2 in the valve body 1, and valve seat 2 is made up of valve opening 3 and slideway 5, and valve opening 3 is communicated with slideway 5, is provided with slidably spool 4 in the slideway 5.
Valve seat 2 valve opening ends and valve body 1 are fixing, and valve opening end outer wall is provided with several grooves 9, and the corresponding position is provided with the rib sheet 10 in some embedding grooves 9 on the valve body 1, and spool 4 has three rib pieces for periphery, and spool 4 heads have sphere chamfering 8.
Slideway 5 is provided with back-up ring 6 with valve opening 3 opposite ends.5 liang of walls of valve seat 2 slideways are provided with several incremental holes 7.
When cold-producing medium when left end enters, spool 4 is pressed to the right, make the sphere chamfering of spool 4 heads and the inclined-plane of valve seat 2 inside form the linear sealing shape, at this moment, because the particular design of spool 4, make the impulsive force of 4 pairs of potted lines of spool very little, owing to airtight fixing between valve body 1 and the valve seat 2, refrigerant can not be flow through from valve member again.When cold-producing medium when right-hand member enters, because of low, spool 4 is pushed to left end in the high left end of pressure right-hand member because the effect of back-up ring 6, thereby controlled the stroke of spool 4.Make valve body open shape for 1 one-tenth, owing to designed several apertures on the wall of valve seat 2, thereby the flow when making the back conducting has reached enough greatly.Thereby effectively increased the conducting flow, reduced noise.
