Description

A kind of worm gear valve
Technical field
The utility model relates to a kind of valve, especially relates to a kind of worm gear valve.
Background technique
The valve used at the fluid control field at present can be summarized as three classes: stop valve, ball valve and gate valve.The sealing surface of stop valve is plane, and fluid passes through valve with the form of bottom in and top out, and its rotary valve plate is perpendicular to the sealing surface upper and lower displacement.Fluid motion is non-linear in stop valve, makes energy loss larger; The sealing surface single face of rotary valve plate bears system internal pressure malleation on valve seat, in case medium contains granule foreign, easily causes leakage; And easy oscillatory stability is poor, and body cavity is large, cavitates, the fluid erosion phenomenon is serious.The rotary valve plate of ball valve is the spheroid perpendicular to valve axis, and its sealing surface is sphere, and not only difficulty of processing is large, and because rotary valve plate rotates under the drive of valve rod, the moment of required rotation is large, more difficult for bigbore such valve operation.The rotary valve plate of gate valve is the flat board perpendicular to the valve body circulation passage, and the motion of rotary valve plate is to move up and down in sealing plane, and the especially bigbore gate valve of gate valve not only operates effort, and the volume of valve body is large, processed complex, must be through casting.
In sum, current three class valves on the market, although each has something to recommend him on structure, its fairly obvious deficiency is also arranged.Application number is that 99249715.9 model utility discloses a kind of control valve for fluids, this valve is comprised of valve body, valve seat, rotary valve plate and valve rod, its valve body is hollow cylinder, valve seat, rotary valve plate and valve body is concentric arranges, having the circular plate valve rod of circulation passage and the kind of drive of rotary valve plate is Worm Wheel System.This valve mechanism is simple, volume is little, rapid operation, but there is following shortcoming in this valve: 1, rotary valve plate rotates around the central shaft that is positioned at the valve seat center, and central shaft affects sealing; 2, on valve seat and rotary valve plate, set circulation passage is fan-shaped, can not be applicable to multiple different fluid medium and multiple circulation flow, very flexible be set.
The model utility content
The purpose of this utility model be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of simple in structure, be easy to manufacture, the fluid of valve is controlled the good worm gear valve of the linearity simultaneously.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of worm gear valve, it is characterized in that, comprise valve body, fixedly valve plate, rotary valve plate and worm screw, described fixedly valve plate and rotary valve plate coaxially are fixed on valve body, described fixedly valve plate center is provided with the mandrel that passes rotary valve plate, described rotary valve plate rotates around mandrel, described worm screw is located in the worm screw case that the valve body periphery tangentially arranges, described rotary valve plate edge be provided with worm screw on the wrom tooth of wrom tooth engagement, described fixedly valve plate is provided with first-class circulation passage, and described rotary valve plate is equipped with the second circulation passage.
First-class circulation passage on described fixedly valve plate is made as a plurality of bar holes, and the plurality of bar hole is fan-shaped mode and distributes.
First-class circulation passage on described fixedly valve plate is made as a plurality of equally distributed circular holes.
First-class circulation passage on described fixedly valve plate is made as a plurality of fan shaped boreholes.
Second circulation passage on described rotary valve plate is made as a plurality of bar holes, and the plurality of bar hole is fan-shaped mode and distributes.

Second circulation passage on described rotary valve plate is made as a plurality of fan shaped boreholes.
Described worm screw case is provided with sealing gland, and described worm screw one end passes sealing gland, and the other end is tightly connected by axle sleeve and sealing gland.
Between described rotary valve plate and mandrel, be provided with stationary spring.
Compared with prior art, the utlity model has following advantage:
1, between rotary valve plate and mandrel, be provided with stationary spring, not only that rotary valve plate is fixing reliable, and fixing valve plate has been formed to certain initial sealing power.
2, worm screw case mouth is provided with sealing gland, has increased sealability.
3, different circulation passages is set as required, can adapts to different flowing mediums, and the circulation flow that changes flowing medium, can also be applicable to need, in the conveyance conduit filtered, make valve applications extensive flexibly, and have good fluid guide line.
The accompanying drawing explanation
Fig. 1 is the structural representation that first, second circulation passage of the utility model is bar hole.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is that the first-class circulation passage of the utility model is that bar hole, second circulation passage are the structural representation of fan shaped borehole.
Fig. 4 is the structural representation that first, second circulation passage of the utility model is fan shaped borehole.
Fig. 5 is the structural representation that first, second circulation passage of the utility model is circular hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 1-2, a kind of worm gear valve, comprise valve body 1, fixedly valve plate 2, rotary valve plate 3 and worm screw 4, described fixedly valve plate 2 coaxially is fixed on valve body 1 with rotary valve plate 3, described fixedly valve plate 2 centers are provided with cylindrical body mandrel 5, described rotary valve plate 3 is around mandrel 5 rotations, between described rotary valve plate 3 and mandrel 5, be provided with stationary spring 11, described worm screw 4 is placed in the worm screw case 6 that valve body 1 periphery tangentially arranges, described rotary valve plate 3 edges are provided with wrom tooth 3a, with the wrom tooth 4a engagement on worm screw 4, described fixedly valve plate 2 is provided with circulation passage 2a, rotary valve plate 3 is provided with circulation passage 3b.When worm screw 4 rotation, driven rotary valve plate 3 is rotated around mandrel 5, thereby valve is operated.When the circulation passage 2a on fixing valve plate 2 was rotated valve plate 3 and covers, valve was closed; When the circulation passage 2a on fixing valve plate 2 was not covered, valve opening, the area of the circulation passage 2a do not covered were the circulation area of valve.Described worm screw case 6 is provided with sealing gland 7, and described worm screw 4 one ends pass sealing gland 7, and described sealing gland 7 seals worm screw 4 and worm screw case 6 by axle sleeve 8, bolt 9 and seal ring 10.
