Technical field
The utility model belongs to valve, especially is used for air-conditioning to regulate the bidirectional throttling valve of cooling and warming rate-of flow relevant with a kind of.
Background technology
Choke valve is through changing throttling cross section or the chock length valve with the control fluid flow.Use a kind of bidirectional throttling valve to realize the flow-control of cooling and warming medium in the air-conditioning system.Existing bidirectional throttling valve is as shown in Figure 1; Adopt double spool, bivalve seat to join the structure of back-up ring; Mainly form the refrigeration orifice union by first spool 3, first valve seat 2, mainly be made up of second spool 5, second valve seat 6 and heat orifice union, back-up ring 4 is between two groups of assemblies; Valve seat, back-up ring are fastened on tube connector 1 inner chamber through reverse riveting and form bidirectional throttling valve.Such choke valve needs a plurality of spools, valve component, complex structure, and difficulty of processing is high, and manufacturing cost is high; Spool and valve seat collide easy abrasion for a long time, can strengthen leakage rate, thereby cause choke valve shortening in service life.
The utility model content
The purpose of the utility model is exactly that existing bidirectional throttling valve difficulty of processing is high with manufacturing cost, the defective of assembly easy abrasion in order to overcome, and provides a kind of and makes relatively easily, the idle call bidirectional throttling valve of low cost of manufacture, long service life.
For this reason; The utility model adopts following technical scheme: the idle call bidirectional throttling valve; Comprise tube connector, valve seat, refrigeration choke valve and heat choke valve; Valve seat is fastening to be installed in the tube connector inner chamber, and valve seat outer wall and tube connector internal chamber wall form and closely cooperate, and the tube connector inner chamber is separated into first chamber and second chamber; Described refrigeration choke valve with heat choke valve and comprise valve pocket, spool, throttling passage and spool position-limit mechanism respectively, two throttling passages all are arranged on the described valve seat, two valve pockets are divided into the two ends of described valve seat; Valve pocket is provided with opening; The installation channel that is used for spool, spool are placed in the valve pocket, and the spool position-limit mechanism is installed on the valve pocket opening part; Spool is spacing in valve pocket; The spool position-limit mechanism is provided with spool and drives circulation road, and throttling passage and spool drive circulation road and all be communicated with valve pocket, is positioned at the inner oral area of spool driving circulation road of valve pocket and the two ends that the throttling passage inner port partly is located at the spool glide direction; The throttling passage of refrigeration choke valve is communicated with described second chamber, and spool drives circulation road and is communicated with described first chamber; The throttling passage that heats choke valve is communicated with described first chamber, and spool drives circulation road and is communicated with described second chamber, and it is characterized in that: described spool is connected to form by seal section and guide section; Seal section is the Rotary-table shape, the inner oral area of the described throttling passage of path place face; The guide section side is by cooperate spigot surface that play the guiding role and the guide face that plays guide functions to connect to form with the valve pocket inwall; Point on the guide face less than the distance of the point on the spigot surface to the guide section axis, forms flow-guiding channel to the distance of guide section axis on guide section.
When the utility model plays the refrigeration throttling action; Refrigerant is divided into two-way after second chamber entering of tube connector; One the tunnel gets into the throttling passage of refrigeration choke valve, and spool is moved toward one thruster of spool position-limit mechanism, opens the inner oral area of throttling passage; Medium gets into behind the valve pocket flow-guiding channel from the spool and flows to spool and drive circulation road, drives circulation road from spool then and flows to first chamber; Another road drives circulation road through the spool that heats choke valve and gets into valve pocket; Spool is passed toward the inner oral area of throttling passage; The inner oral area of sealing throttling passage makes bidirectional throttling valve have only throttling passage, flow-guiding channel, the spool of refrigeration choke valve to drive circulation road and forms the path from second chamber to first chamber.When rising when heating throttling action; Medium is divided into two-way after first chamber entering of tube connector; One the tunnel gets into the throttling passage that heats choke valve, and spool is moved toward one thruster of spool position-limit mechanism, opens the inner oral area of throttling passage; Medium gets into behind the valve pocket flow-guiding channel from the spool and flows to spool and drive circulation road, drives circulation road from spool then and flows to second chamber; Another road drives circulation road entering valve pocket through the spool of refrigeration choke valve; Spool is passed toward the inner oral area of throttling passage; The inner oral area of sealing throttling passage makes bidirectional throttling valve only heat the throttling passage of choke valve, flow-guiding channel, the path of spool driving circulation road composition from second chamber to first chamber.
As to such scheme replenish and perfect, the utility model also comprises following technical characterictic:
Described valve seat outer wall upper edge circumferentially is provided with groove, and described tube connector tube wall convex snaps in this groove, and valve seat and tube connector are interfixed.
Described valve seat two ends are provided with filtering screen, and filtering screen and tube connector inwall are fastening.
Described spool position-limit mechanism is the hollow back-up ring, and the hollow cavity of back-up ring drives circulation road as described spool.
The described throttling passage oral area that is positioned at valve pocket is provided with the sealing pair that cooperates with spool, plays the enhancing sealing function.
Further, described sealing pair is the taper cambered surface, can also be the circular arc convex.
Described refrigeration choke valve laterally arranges with the throttling passage that heats choke valve.
Guide face on the described spool is the plane.
Guide face on the described spool can also be the plane combination, and making described flow-guiding channel become cross section is " the indent groove of [" shape.
Guide face on the described spool can also be plane and arc surface combination, and making described flow-guiding channel become two sides is that plane, bottom surface are the indent groove of convex arc surface.
Guide face on the described spool is a plurality of, is provided with at interval with spigot surface.
Use the utility model can reach following beneficial effect: through be provided with simultaneously on the valve seat in being fixed in tube connector channel flow to opposite refrigeration choke valve with heat choke valve, reduced parts, practiced thrift cost; Spool all moves in the valve pocket on valve seat, has avoided spool that the fastening of valve seat and tube connector arrived in the shock effect of valve seat, the leakage that can not produce valve seat and the fastening place of tube connector, the service life of prolongation choke valve.
