Description
Technical field
The utility model is related to a kind of valve, the specifically multistage regulating valve for adjusting flow.
Background technology
Regulating valve also known as control valve, be in industrial automation process control field, it is defeated by receiving regulation unit
The control signal gone out goes to change the final control member of the technological parameters such as rate-of flow, pressure, temperature, liquid level by power operation
Part.Although existing regulating valve has diversified structure, it is difficult to the accurate adjusting to flow；Can not thus it expire
The needs of sufficient automation control.
Utility model content
The purpose of the utility model is to overcome the deficiencies in above-mentioned background technology, provide a kind of multi-stage regulating valve, the adjusting
Valve should be able to accomplish that the classification to flow is adjusted, and have the characteristics that adjust accurate.
Technical solution provided by the utility model is：
A kind of multi-stage regulating valve, including being formed with the valve body of flow inlet, water export and valve seat, being moved along own axes
Ground is vertically oriented on valve body and the valve rod of switch cooperation can be carried out with the valve seat and drives the actuating unit of the valve rod；
It is characterized in that several flow deflectors horizontally disposed and mutually overlap up and down are provided between the flow inlet and valve seat, often
Open the valve rod hole for being formed with and coordinating with valve stem slides in the center of a flow deflector；It opens to be formed on one face of each flow deflector and surround and connect
The annular diversion trench of port valve rod aperture, annular diversion trench are also communicated by several spout holes with another face of flow deflector, in favor of
Water flows through spout hole and from top to bottom flows；The annular diversion trench thickness of several flow deflectors, is from top to bottom thinned successively, with
Realize the Accurate Classification of flow.
The bottom of the valve rod makes the mating surface for having and being matched with valve seat, is coordinated with realizing with the switch of valve seat.
Spout hole quantity in each flow deflector is equal, and the overflow axially bored line of each adjacent baffle is staggered one up and down respectively
Angle is determined, to slow down the flow velocity between adjacent level.
The supporting rack as stem guiding is laid between the flow inlet and flow deflector, is offered on supporting rack several
A water hole conducive to water conduction.
The beneficial effects of the utility model are：
As a result of the structure of overlapping flow deflector, it is thus achieved that flow accurately adjusts and the purpose of control, and adjust
Section is convenient, reliable, especially suitable for flow adjustment range is big, High Pressure Difference operating mode, is welcome by user.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
Specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
Multi-stage regulating valve shown in FIG. 1, the top of valve body 1 is formed with flow inlet 7, lower part is formed with water export 17 and valve seat
3, valve rod 5 can be movably vertically oriented on along own axes on valve body and can be carried out with the valve seat switch cooperation (valve rod
Bottom makes the mating surface 5-1 for having and being matched with valve seat, is coordinated with realizing with the switch of valve seat), actuating unit 9 (is typically electricity
The gearbox that machine drives) the driving valve rod.These are similar with existing regulating valve.
The improvement of the utility model is that several flow deflectors are provided between flow inlet and valve seat, these are horizontal
It arranges and mutually overlapping is (visible in figure up and down：Flow deflector is from bottom to top followed successively by the first flow deflector 4, the second flow deflector 16, third
Flow deflector 15, the 4th flow deflector 14, the 5th flow deflector 13, the 6th flow deflector 12, the 7th flow deflector 11)；In each flow deflector
Centre, which is opened, is formed with valve rod hole, and valve rod also prevents flow that it is avoided to enter valve rod while insertion valve rod hole is slidably matched
Hole；(display is lower surface in figure in one face of each flow deflector；Obviously, also can be in upper surface) on open be formed with around and communicating valve
The annular diversion trench (the annular diversion trench 11-1 of the 7th flow deflector in such as figure) of rod aperture, annular diversion trench also passes through several spout holes
(the spout hole 11-2 of the 7th flow deflector in such as figure；2-4 spout hole can be made on usually each flow deflector) it is another with flow deflector
One face communicates, and is from top to bottom flowed so that water flows through spout hole；The annular diversion trench thickness of several flow deflectors, by
It is thinned successively under above, to realize the Accurate Classification of flow；Specific thickness can be selected as needed.
Preferably, the spout hole quantity in each flow deflector is equal, and the overflow axially bored line difference of each adjacent baffle
Be staggered certain angle (specific angle can determine as needed), to slow down the flow velocity between adjacent level.
Preferably, the supporting rack 6 as stem guiding is laid between the flow inlet and flow deflector, to increase valve
The stability of bar operation；The usual supporting rack can be integrally formed with valve body.Several water holes are offered on supporting rack, in favor of
Water conduction.
Also have in figure：Handle 8, filler 10.
The operation principle of the utility model is：When the mating surface of valve rod bottom end is against valve seat, valve is closed.
When actuating unit band ovable valve stem rises slowly, valve is opened；The water poured in from flow inlet after the water hole of supporting rack,
Respectively from the spout hole flow down of each flow deflector；When the mating surface of valve rod rise to it is concordant with the valve rod hole of a certain flow deflector
When, flow is to converge to valve rod hole from the diversion trench of the flow deflector, then again from valve rod hole flow down, until outflow water flows out
Mouthful；Since the water conservancy diversion slot thickness of these flow deflectors is from bottom to top thickening successively, one is often opened in valve rod uphill process and is led
Chute, flow just become larger (water conservancy diversion slot thickness determines the flow of flow, and can preset), until valve rod rises
To highest order, the flow of output is maximum stream flow；Realize the purpose that flow is accurately adjusted.
