Section.
Compared with the prior art, the utility model has the following beneficial effects:
The utility model provides a kind of anti-blocking regulating valve, by connecting rotatable eddy flow component on valve rod,
When work, when fluid is flowed up by the gap between spool and valve seat, eddy flow component is pushed to make eddy flow component
Rotation, meanwhile, fluid under the rotary action of eddy flow component to shunting around eddy flow component so that fluid is in valve body
Cavity wall carries out wiper, so that the impurity such as particle in fluid can not be stopped in middle cavity wall, and then realizes anti-blocking mesh
's；Regulating valve structure in the utility model is simple, reliable and stable under working condition, and extends the service life of valve,
Degree of regulation is high.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Specific embodiment
The technical solution in the utility model is further illustrated with reference to the accompanying drawings and embodiments.
As shown in Figure 1, the utility model proposes a kind of anti-blocking regulating valves, including valve body as a kind of preferred embodiment
1, valve rod 2, spool 3 and valve deck 4 are provided with valve body middle chamber 5 in the valve body 1, are provided with valve seat in the lumen 5 of the valve body 1
6, the valve body 1 offers an import 7 and one outlet 8 positioned at 3 two sides of spool, is vertically provided in the middle part of the valve deck 4
One valve rod mounting hole 9, the valve rod 2 are threaded through in valve rod mounting hole 9,2 lower end of valve rod connection spool 3, on the valve rod 2
What is also rotated is connected with an eddy flow component 10, and the eddy flow component 10 is located in the lumen 5, and is located at 3 top of spool；Institute
It states valve rod 2 to move up and down with movable valve plug 3, changes the gap between spool 3 and valve seat 6 to change circulation area, realize flow
It adjusts；The spool 3 is preferably pyramidal structure, and taper valve core 3 and the cooperation of valve seat 6 are able to achieve cutoff function, and the operation is stable shakes
It is small, it is not likely to produce noise.
Above scheme at work, when fluid is flowed up by gap between spool 3 and valve seat 6, by eddy flow component
10 push to rotate eddy flow component 10, meanwhile, fluid is under the rotary action of eddy flow component 10 to around eddy flow component 10
It shunts, so that fluid carries out wiper to 5 inner wall of lumen of valve body 1, so that the impurity such as particle in fluid can not be
5 inner wall of lumen stops, and then realizes anti-blocking purpose；Regulating valve structure in the utility model is simple, and working condition is reliably steady
It is fixed, degree of regulation is improved, and be able to extend the service life of valve.
Preferably, the eddy flow component 10 includes multiple swirl vanes 11, the multiple swirl vane 11 is around same
Direction spiral, and the bottom end of the eddy flow component 10 is bigger than top end diameter.The effect of eddy flow component 10 is the fluid so that passing through
Eddy flow is generated, so that the fluid of eddy flow generates wiper effect to 5 inner wall of lumen of valve body 1, in fluid is made with this
Grain under the action of eddy flow wiper from outlet 8 flow out, guarantee valve body 1 in fluency, play the role of it is anticlogging, therefore, rotation
Stream unit 10 need to be rotatablely connected with valve rod 2, specifically can be using bearing connection or other rotation connection modes, and pass through
Multiple swirl vanes 11 around same direction spiral can be achieved with this function, and structure is simple, low in cost, and effect is very aobvious
It writes, there is fabulous promotional value.
Preferably, the middle part of the valve seat 6 is vertically provided with the spool that can seal cooperation with the spool 3
Positioning jack 13, the valve rod 2 are inserted into spool positioning jack 13 and connect with valve body 1；By the way that spool positioning jack 13 is arranged, so that
Structure setting is more reasonable, and spool 3 is positioned by spool positioning jack 13, relatively reliable when adjusting.
Preferably, the spool 3 is threadedly coupled with the valve rod 2.Valve in the utility model is due to pole
Good anti-clogging effect, is especially suitable in the multiphase flow transportation system containing solid particle, but when in use, in fluid
Particulate matter abrasion can be brought to spool 3 and eddy flow component 10, therefore by spool 3 and valve rod 2 using being threadedly coupled, in order to
Replacement and maintenance.
Preferably, the bottom diameter of the eddy flow component 10 is smaller than the top end diameter of spool 3, the top of eddy flow component 10
Hold diameter bigger than the top end diameter of spool 3.Setting is to further decrease around 3 top of spool to eddy flow component in this way
The fluid of 10 flowings and the swirl vane 11 of eddy flow component 10 generate central collision, and this case is avoided to can reduce eddy flow portion
The abrasion of part 10, extends the service life of eddy flow component 10, while avoiding generating partial high pressure, so that more steady under working condition
It is fixed, reduce noise.
Preferably, being equipped with multiple bolts 14 on the valve deck 4, valve deck 14 is solid by bolt 14 and the locking of valve body 1
It is fixed；It is arranged in this way, valve deck 4 and valve body 1 are easy to connect, fixed reliable.
Preferably, filler assembly 15 and gland 16 are provided with above the valve rod mounting hole 9, the filler pressure
Lid 16 is connect with 4 threaded upper ends of valve deck, and gland 16 compresses filler assembly 15；It is arranged by this, keeps filler assembly 15 tight
It is tightly extruded on valve rod 2, so that sealing performance is more preferable, is not easy to leak.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
