Abstract

The utility model discloses a unidirectional throttle valve used for heat pump air conditioning, consisting of a throttle valve body which consists of a valve body, a valve seat which is composed by a valve hole and a slide way is sealed and fixed in the valve body, a sliding valve core which is arranged with an axial direction pore is arranged in the slide way, one end of the slide way connects with the valve hole, and the other end is arranged with a net seat whose port which connects with a filter screen fixedly. The valve body and the valve seat of the utility model are sealed and fixed, the valve core and the valve seat uses spherical line seal, an increasing circulation channel is added and arranged between the valve seat and the net seat, therefor increasing the guide circuit flow and reducing the noise. Compared with the current technology, the design is more reasonable, with good sealing performance, reliable performance, long service life, which can be used widely in air conditioning system.

Description

A kind of one-way throttle valve that is used for heat pump type air conditioner

Technical field

The utility model relates to a kind of novel one-way throttle valve, refers in particular to a kind of one-way throttle valve that is used for heat pump type air conditioner.

Background technique

In the prior art, the structure composition of heat pump air conditioner mainly contains compressor, condensation device, throttle part and vaporizer and forms, in air-conditioning system, throttle part is the critical component of decision heat pump performance, traditional throttle element by a main capillary tube, a secondary capillary tube, one-way valve, filter, and each link form, in use, by the unidirectional control action of one-way valve, the realization air-conditioning system is in refrigeration or heat two different flows in the stream.Defectives the such as obviously throttle part of conventional construction exists and forms complexity, and volume is big, and energy loss is serious; More because of its soldering point again, easily produce serious Accident due to qualitys such as leakage during use.

Summary of the invention

The one-way throttle valve that is used for heat pump type air conditioner that the utility model provides a kind of simple in structure, system pipeline to simplify.

A kind of one-way throttle valve that is used for heat pump air conditioner, comprise throttle body, body comprises valve body, sealing and fixing has valve seat in the valve body, and valve seat is made up of valve opening and slideway, is provided with slidably spool in the slideway, spool is provided with axial pore, the spool periphery has three rib pieces, has the boss that cooperates with valve base inner wall on the rib piece, and the spool head has the sphere chamfering.

Described valve seat valve opening end outer wall is provided with some grooves, and the corresponding bearing of valve body is provided with some pressures and is embedded in the interior rib sheet of groove.

Be equipped with several incremental holes on two walls of described reticulum and slideway, each incremental hole is communicated with the incremental passage of formation.

Described slideway is provided with reticulum, is fixedly connected with filter screen on the reticulum port.

The utility model is integrated in one filter, capillary tube, one-way valve and the connecting tube of conventional throttle assembly, has overcome traditional capillary module and has formed defectives such as complicated, that volume is big, energy loss is serious; Spool adopts the triangular profile, has effectively alleviated the spool deadweight, in sliding process, wearing and tearing have been reduced with valve base inner wall, in the moment of spool closure, effectively reduced impact force, thereby increased working life the potted line of spool sphere chamfering and slide ramp cooperation formation; The slideway port is provided with reticulum, and reticulum has filter screen outward, and spool places in the valve body slideway, and valve seat and valve body adopt groove and rib sheet to press build-in fixed, have effectively increased the rigidity of whole valve member; Be equipped with several incremental holes on reticulum and the valve seat, each incremental hole is communicated with the incremental passage of formation, has effectively increased reverse through-current capacity, has reduced noise; Spool can be free to slide in slideway, spool head and valve body cooperation place are provided with the sphere chamfering, design has the flow control aperture in the spool, this aperture forms through precise design and manufacturing, spool is under closed state, because of between valve seat and valve body, be sealing state between spool head and valve body, thereby force refrigerant in this aperture, to flow through, make that the flow by whole valve member reaches design load; Outside valve body, be printed on the numbering corresponding, be convenient to logistics management with the spool specification.Compared with prior art, the utility model design is more reasonable, good airproof performance, reliable performance, long service life.

Description of drawings

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is the structure for amplifying schematic representation of A part among Fig. 1.

Embodiment

Show as Fig. 1,2, a kind of one-way throttle valve that is used for heat pump air conditioner comprises throttle body, and body comprises valve body 1, two end interfaces of valve body 1 can link to each other with different connecting tube or other air supply rate, and can be installed on the indoor set of air-conditioning or outdoor unit Anywhere.

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 6, is provided with slidably spool 4 in the slideway 6, and valve seat 2 valve opening end outer walls are provided with some grooves 12, and valve body 1 corresponding bearing is provided with some pressures and is embedded in the interior rib sheet 13 of groove 12.

Spool 4 is provided with axial pore 5, and spool 4 peripheries have three rib pieces, and the rib piece is provided with the boss that cooperates with valve seat 2 inwalls, and spool 4 heads are provided with the sphere chamfering 14 that cooperates with the valve opening end.

Slideway 6 one ends are communicated with valve opening 3, and the other end is provided with reticulum 7, is fixedly connected with filter screen 8 on reticulum 7 ports.Two walls of valve seat 2 slideways 6 are provided with several incremental holes 11, also are provided with several incremental holes 9 on the reticulum 7, and the

incremental hole

9,11 of homonymy is communicated with the incremental path 10 of formation.

Have coding 15 on the valve body 1 with spool 4 corresponding specification.

When refrigeration agent enters from the one-way throttle valve left end, behind filter screen 8, the refrigeration agent of cleaning enters in the valve body 1, spool 4 is pushed away to the right, valve body 1 is airtight with valve seat 2, and 2 sealings of spool 4 and valve seat force in the axial pore of refrigeration agent from the spool 4 and pass through, the axial pore of spool 4 is according to the flow precise design, and feasible refrigeration agent by whole one-way throttle valve reaches specified flow.

When refrigeration agent when the one-way throttle valve right-hand member enters, because the effect of pressure makes spool 4 shift to left end reticulum 7 places, flow out in the incremental hole 9 of refrigeration agent on through the incremental hole 11 on valve seat 2 slideways 6, to incremental path 10 from reticulum 7, thereby effectively increased the conducting flow, reduced noise.
