Abstract
A multiorifice sleeve shaft angle type control valve. At the juncture of the upper and lower valve bodies is clipped a circular casing with many orifices. The circular casing is put in a circular sleeve, the top end of which is connected to a drawbar which, in turn, is connected to a driving mechanism, enabling the circular sleeve to move on the circular casing to control water flow. This valve is effectively in controlling operation limit.
Description
Technical field
A kind of many spray orifices sleeve control valve, it belongs to the machinery valve industry field, is particularly suitable for employed valve in supply and drain water system and the industrial fluids system.
Background technique
In the prior art, especially in industrial fluids power conduit system, valve is primary element of realizing whole system automation control.What its assurance system controlled is safe, instant and effective, and central topmost factor is the operation of pressure adjusting and flow control valve.Yet, for the control valve of these remote controls, the operation that requirement is can be under any condition stable, and can under any mode of operation, can not cause the infringement of valve body and system.It is the problem place that this field domestic demand solves.
The common problem that exists on the control valve of routine is:
1. the operation operating mode is restricted: when High Pressure Difference or big flow generation, traditional rotary-type or ball-type control valve has performance constraint to a certain degree.Can produce cavitation and oscillation phenomenon.
2. metering characteristics are undesirable: in the whole opening-closing process of valve, opening flow and change with the non-linear ratio with the flap aperture, is that approximately linear changes in intermediate space only perhaps.When the flow that needs convection cell carries out continuous process control, can only obtain a kind of false linear ratio relation by additional circuitry and drive unit.
3. easily vibration: under the flow action of high pressure, high speed, flow control valve very easily produces violent oscillation phenomenon.Particularly, very harmful in engineering is used to the control of high flow capacity fluid.
4. easily produce cavitation: the normal flow control valve damages valve and pipeline because the factor of structure and working principle produces cavitation phenomenons inevitably, has shortened its working life greatly.
Summary of the invention
The present invention solves the defective that has been existed by technology by following technical solution: this multi-orifice sleeve shaft-angle control valve agent structure is a spray orifice body, frame at the spray orifice body is covered with a sleeve, the spray orifice body is provided with a plurality of open-works, front end is by end bracket enclosed, and moving of sleeve finished by driving mechanism.Control sleeve when the driving arm of driving mechanism and move forward and backward the water flow of controlling the spray orifice body, this driving mechanism can be manual, automatic or surge.Change circulation area, and then control fluid flow and the pressure that passes through, and the water column of ejection is impacted on the valve central axis mutually, it weakens the speed energy of water column, avoids valve body to damage, and has reduced the vibration and the noise coefficient of valve.
Accompanying drawing and explanation
In order to be described further as follows to multi-orifice sleeve shaft-angle control valve concrete structure of the present invention in more detail:
Fig. 1 is a multi-orifice sleeve shaft-angle control valve structure cut-away view of the present invention.
Symbol description among the figure:
1 driving mechanism
2 sleeves
4 spray open-works
5 seal rings
6 upper valve bodies
7 times valve bodies
8 end caps
11 stretch
Specific implementation method
As shown in Figure 1, upper valve body 6 and the round body 21 of following valve body 7 jointing crimping one less than body cavity, and lay respectively on upper valve body 6 and the following valve body 7, the surface of round body 21 is provided with a plurality of spray open-works 4, these round body 21 1 ends are open, and the other end is affixed with end cap 8, fixing position is provided with a seal ring 5, the round body 21 peripheral sheathed one round sleeves 2 on upper valve body 6, and the upper end of this round sleeve 2 connects a stretch 11 and is connected with driving mechanism 1, when driving stretch 11, does when moving up and down by drive unit 1, round sleeve 2 moves up and down with doing, and current flow out from spray open-work 4, because the outflow area of round sleeve 2 control spray open-works 4, thereby, the flow of water can be controlled effectively, and the water column energy through the spray open-work 4 effect, energy reduces greatly, therefore, can effectively operate.
By as above structure Design, this control valve has stable flow velocity and has overcome cavitation and vibration, though when peak rate of flow and High Pressure Difference also without any vibration, even have at water outlet under the situation of negative pressure and also can operate.
In sum, multi-orifice sleeve shaft-angle control valve is really than relevant performance constraint in the prior art, and flow control reduces on vibration and working life all increasing.
Claims (2)
