Description
Technical field
The utility model relates to a kind of mesh sleeve-type regulating valve.
Background technique
In the prior art, the mesh sleeve-type regulating valve is a kind of taper hole structure of special arrangement, and each position of flow warp is annular to spray formula state, so fluidised form is more even, and effect of energy dissipation is good.Because the acceleration of cone shape hole, make fluid leave fast the valve wall and do not have pressure to recover, effectively reduced the erosion to the valve wall, so cavitation-preventive is effective; Because arranging accurately in the hole, so adjusting function is good, and degree of regulation is high, and the linear adjustment degree is good, modification stability and be easy to control.In addition, also have flow, pressure reduction control range large, the characteristics such as noise, vibration are little.Because these unique features, this valve is widely used on the pipelines such as tap water, water supply, circulating water, large-scale delivery water project, pipe network, as flow and the pressure of regulating pipeline or pipe network fluid.Be particularly suitable for the operating mode of heavy caliber (bore is greater than DN1000), High Pressure Difference, large Pressure reducing ratio, wide range of traffic adjusting.The effective equipment that also be applicable to the dam flood-discharge energy dissipating, discharge water, the water turbine bypass discharges water the energy dissipating pressure regulation, accent flows.
But also there is following shortcoming in the mesh sleeve-type regulating valve at present:
1. if be applied in the High Pressure Difference pressure regulation energy dissipating situation, because pressure reduction is very high, the energy that valve need to consume is huge, therefore the taper hole aperture certainly will require less, thereby reach good effect of energy dissipation, but because the reducing of taper hole aperture, foreign material just are easy to stop up taper hole, cause this valve flow resistance to increase, do not reach flow or pressure that working condition requirement is regulated, produce and stop up or failure of adjustment;
2. in design during this valve, require the fluid ejection go after speed in the central position can not be too large, be conducive to so stable, control noise and the vibration of valve, so that the design in aperture also requires is smaller, this has just increased the possibility that valve blockage lost efficacy;
3. owing to be taper hole, so the possibility that forward stops up increases, and the pressure flow reverse flow is then discharged easily and stopped up foreign material.
Therefore, providing a kind of mesh sleeve-type regulating valve that can automatically get rid of during operation foreign material is the technical problem that those skilled in the art need solution badly.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to provide a kind of mesh sleeve-type regulating valve, and it can get rid of foreign material during operation automatically.
To achieve these goals, the utility model provides a kind of mesh sleeve-type regulating valve, and it comprises valve body, stationary magazine creel, moving cylinder, adjusting taper hole and pollutant exhaust hole, and described pollutant exhaust hole is positioned at described valve body mid-rear portion.
Preferably, described pollutant exhaust hole is square.
Preferably, also comprise water supply line, waste pipe, water supply valve, wastewater valve, the first sleeve adjusting valve, the second sleeve adjusting valve, discharging separating valve; It is outside that described moving cylinder is placed in described stationary magazine creel, described water supply line, waste pipe are arranged on valve body the same side, described water supply valve, wastewater valve are arranged at respectively on described water supply line, the waste pipe, described the first sleeve adjusting valve, the second sleeve adjusting valve are arranged on the described valve body, and described the first sleeve adjusting valve and described the second sleeve adjusting valve lay respectively at the valve body both sides, and described discharging separating valve is positioned at described valve body afterbody.
Compared with prior art, mesh sleeve-type regulating valve provided by the utility model, it comprises pollutant exhaust hole and moving cylinder, described pollutant exhaust hole is positioned at described valve body mid-rear portion, therefore, regularly moving cylinder is reached the square opening position and carries out blowdown, reduced the possibility that valve blockage lost efficacy, in the time of so just need not worrying design regulate the less problem of taper hole, can design well the high performance valve of High Pressure Difference, high stable, low vibration, low noise, and effectively reduced the maintenance cost of pipe-line system.
Further preferably in the mode of execution, described pollutant exhaust hole is square, can further improve filth-discharging effect, and be beneficial to processing.
Further preferably in the mode of execution, also comprise water supply line, waste pipe, water supply valve, wastewater valve, the first sleeve adjusting valve, the second sleeve adjusting valve, discharging separating valve; It is outside that described moving cylinder is placed in described stationary magazine creel, described water supply line, waste pipe are arranged on valve body the same side, described water supply valve, wastewater valve are arranged at respectively on described water supply line, the waste pipe, described the first sleeve adjusting valve, the second sleeve adjusting valve are arranged on the described valve body, and described the first sleeve adjusting valve and described the second sleeve adjusting valve lay respectively at the valve body both sides, and described discharging separating valve is positioned at described valve body afterbody.Therefore, moving cylinder can be moved to closing the valve direction, throttle down, then, close successively the discharging separating valve, open the backwash water supply valve, open the backwashing wastewater valve, at this moment, by moving cylinder is moved to valve opening position, the dirt that is blocked in the taper hole the inside will be discharged from the backwashing wastewater valve by the drain pipe in the moving cylinder, and it is mobile repeatedly to allow moving cylinder come and go, and can constantly discharge stopping up dirt.This has further improved pollution discharge capability, and valve is worked better, thereby has increased Systems balanth, has prolonged the life-span of valve.

Embodiment
The purpose of this utility model provides a kind of mesh sleeve-type regulating valve, and it can get rid of foreign material during operation automatically.
In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
Please refer to Fig. 1, in one embodiment, mesh sleeve-type regulating valve provided by the utility model is mainly by valve body 1, stationary magazine creel 5, moving cylinder 2, regulate taper hole 4, pollutant exhaust hole 3, water supply line, waste pipe, water supply valve, wastewater valve, the first sleeve adjusting valve, the second sleeve adjusting valve, the compositions such as discharging separating valve, described pollutant exhaust hole 3 is square and is positioned at described valve body 1 mid-rear portion, described moving cylinder 2 is placed in described stationary magazine creel 5 outsides, described water supply line, waste pipe is arranged on valve body 1 the same side, described water supply valve, wastewater valve is arranged at respectively described water supply line, on the waste pipe, described the first sleeve adjusting valve, the second sleeve adjusting valve is arranged on the described valve body 1, and described the first sleeve adjusting valve and described the second sleeve adjusting valve lay respectively at valve body 1 both sides, and described discharging separating valve is positioned at described valve body 1 afterbody.
