Description
Technical field
It the utility model is related to Refrigeration ＆ Air-Conditioning throttle valve technology field, and in particular to a kind of duct type bidirectional throttle
Valve.
Background technology
Existing Refrigeration ＆ Air-Conditioning duct type bidirectional throttling valve, different abilities are carried out in positive and negative both direction to realize
Throttling, as shown in Figure 1-2, the valve element of two valve seats and two different sizes is provided with body.When refrigerant towards some
When direction is flowed, a valve element plays throttling action by " short circuit ", another valve element；When refrigerant reverse flow, two valve elements
Effect also exchanged.I.e. no matter refrigerant whichaway flows, and all only has a valve element to play throttling action all the time.It is but this
Duct type bidirectional throttling valve has used two valve seats, causes material cost and processing charges higher, and throttle member is total
Body length is longer, is not suitable for the occasion of axially mounted limited space.
Utility model content
The purpose of this utility model on the premise of properties of product are not influenceed, passes through aiming at the deficiency of prior art
Optimizing structure design, a valve seat is saved, so as to save material cost and processing charges, and the totality for shortening throttle member is long
Degree.
The utility model adopts the following technical scheme that：
A kind of duct type bidirectional throttling valve, including body, body is interior to be provided with valve seat and screen pack, is communicated with valve seat
Passage, the side wall of passage end are provided with some pod apertures, the aditus laryngis less than two edge channels are additionally provided with the middle part of described valve seat,
Valve seat is divided into two chambers；Two intracavitary are respectively equipped with fixed spool and movable valve plug, and fixed spool is provided with first segment discharge orifice,
The second throttle orifice, passage, first segment discharge orifice and the second throttle orifice coaxial inner conductor are provided with movable valve plug.
As further improving and supplementing to such scheme, the utility model also includes following additional technical feature：
Described movable valve plug is coordinated with passage using minim gap, and movable valve plug can move along passage is smooth.
Where described movable valve plug the wide arc gap connected with pod apertures is left between the valve seat outer wall and inboard wall of tube body at end.
The second described throttle orifice is less than first segment discharge orifice.
Described valve seat both ends radial direction necking, the valve element progress to both sides is spacing, prevents valve element from skidding off passage.
The conical surface seal of one end coordinates on sphere and passage in described movable valve plug, makes movable valve plug and interchannel
Better tightness.
The conical surface seal of one end coordinates on sphere and passage on described fixed spool, makes fixed spool and interchannel
Better tightness.
It can reach following beneficial effect using the utility model：A valve seat can be saved, so as to reduce material cost
And processing charges；The overall length of throttle member is shortened, makes it to be applied to the smaller occasion in axially mounted space.

Fig. 2 is the structural representation of refrigerant flow direction from right to left in prior art choke valve.
Fig. 3 is the structural representation of refrigerant flow direction from left to right in the utility model choke valve.
Fig. 4 is the structural representation of refrigerant flow direction from right to left in the utility model choke valve.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 3-4, the utility model is a kind of duct type bidirectional throttling valve.
Duct type bidirectional throttling valve described in the present embodiment, including body 1, body 1 is interior to be provided with valve seat 3 and screen pack 5,
Two ends set screen pack 5 to prevent foreign matter flows into from blocking choke valve, and described valve seat 3 is fixed in body 1 by withholding of technology.
The passage 31 of refrigerant is communicated with valve seat 3, the side wall of the one end of passage 31 is provided with some pod apertures 33, described
The middle part of valve seat 3 be additionally provided with the aditus laryngis 32 less than two edge channels 31, the tapered contraction in both ends, valve seat 3 is divided into two chambers；
Two intracavitary are respectively equipped with fixed spool 2 and movable valve plug 4, and movable valve plug 4 is coordinated with passage 31 using minim gap, moving valve
Core can move along passage 31 is smooth.Left between the outer wall of valve seat 3 and the inwall of body 1 at the place end of movable valve plug 4 and pod apertures
The wide arc gap of 33 connections.The both ends of valve seat 3 all carry out spinning closing-in, so as to for be fastened and fixed valve element 2 or limitation movable valve plug 4
Stroke.Fixed spool 2 is provided with first segment discharge orifice 21, is provided with the second throttle orifice 42 in movable valve plug 4, and the second throttle orifice 42 is small
In the diameter of first segment discharge orifice 21, passage 31, the three's coaxial inner conductor of 21 and second throttle orifice of first segment discharge orifice 42.
Further, the conical surface 22 on described fixed spool 2 and the sealing of sphere 34 of one end on passage 31 coordinate.
Further, the conical surface 41 in described movable valve plug 4 and the sealing of sphere 34 of one end on passage 31 coordinate.
This practical operation principle is as follows：
When direction from left to right flowing of the refrigerant by diagram 3, refrigerant flows through the first segment of fixed spool 2 successively
Discharge orifice 21, the middle part aditus laryngis 32 of valve seat 3, and promote movable valve plug 4 to move right to extreme position.Due to radial passage on valve seat 3
The flow area in 31 holes is much larger than the flow area of the throttle orifice 42 of movable valve plug 4 second, therefore most refrigerants are via valve seat 3
Upper radial direction pod apertures 33 flow out.Now movable valve plug 4 can be considered plays throttling action by " short circuit ", only fixed spool 2.
When direction from right to left flowing of the refrigerant by diagram 4, refrigerant first promotes movable valve plug 4 to be moved to the left
Extreme position, the second throttle orifice 42, the middle part aditus laryngis 32 of valve seat 3 of movable valve plug 4 are then flowed sequentially through, most afterwards through fixed spool 2
First segment discharge orifice 21 flow out.Because the diameter of first segment discharge orifice 21 of fixed spool 2 is more than the second throttle orifice 42 of movable valve plug 4
Diameter, so when fixed spool 2 only serve through-flow, do not play throttling action, play throttling action is only movable valve plug 4.
It is above preferred embodiment of the present utility model, the scope of protection of the utility model is not limited, for ability
The deformation and improvement that field technique personnel make according to mentality of designing of the present utility model, should all be considered as protection of the present utility model
Within the scope of.
