In the prior art, in order to prevent that fortuitous event from taking place, as having a power failure, the pressure reduction of medium surpasses rating number before and after the valve, the drive unit of valve breaks down or the like, and influences the conveying of control media, then the bypass of generally a manually operated valve being installed all, in order to maintain valve simultaneously, the manually operated valve of two isolation usefulness is installed in the front and back of valve again, obviously, is done increase equipment and pipeline like this, not only take up space but also increase expense, main is existing general valve, can not accomplish Flow-rate adjustment, can not accomplish throttling, actuation time is non-adjustable, wearing and tearing that can not compensating spool especially can not be washed when the valve body preceding pipeline pollutes automatically, can not be with other medium flushing, pollution condition in more can not the direct observation valve body must out of servicely could be keeped in repair when spool damages.

For addressing this problem, a kind of multi-function electromagnetic valve (patent No. 85201792) is authorized by Patent Office of the People's Republic of China, has solved the shortcoming that solenoid valve exists to a certain extent, and mutually new development should be arranged on technical matters.But a filter must be adorned in its front, and filter can not wash with the medium of itself when pollute blocking, and can not if shutdown is unpicked and washed, then influence proper functioning with other medium flushing again.The pollution condition that can not observe the valve body filter screen again intuitively during normal the operation.Moreover when Sealing need be changed in this machine, must shut down, will influence proper functioning like this.

The purpose of this utility model is synthetically to solve above-mentioned a series of problem, proposes a kind of multifunctional rotary valve.

The utility model is finished as follows: valve body is designed to the hollow inner cavity can hold solid of rotation, and some ducts are arranged around the cylindric outside, import and export as medium, the import and export that also useful medium own and other medium wash, one of them rinse mouth is as shielding window, in order to observe the obstruction pollution condition of filter screen.

Solid of rotation cooperates with body cavity, can be made into cone table shape or spherical or cylindric.Inner chamber at solid of rotation is equipped with main valve and auxilliary valve, also is drilled with on the solid of rotation and the corresponding through hole of valve body duct, on medium import duct filter screen is housed, in order to the impurity in the filter medium.In the bottom of solid of rotation one screw rod is arranged, pass the valve body bottom outlet, and be sealed and matched with it, screw on nut, shell tool, spring are in order to regulate the gap between solid of rotation and the valve body.Through hole duct pattern is had nothing in common with each other, form different size, the angie type single channel is arranged, the angie type Twin channel is arranged, straight-through type single channel and Twin channel are also arranged, difference according to the user requires to decide, and the solid of rotation hollow cavity partly both can make a cavity, and a solenoid valve is installed, also can make two cavitys, a dress solenoid valve, a loaded check valve is perhaps all adorned solenoid valve for two.Also be drilled with throttle orifice on the solid of rotation in order to regulate flow.

The one, switching function is if drive unit is an electromagnetic coil, when then switching on, pick up iron core, open auxilliary valve and form pressure reduction, promote main valve, make valve opening, medium is discharged to outlet passage by filter screen from inlet passage, otherwise, during outage, auxilliary valve cuts out, and a part of medium leads to main chamber from throttle orifice, makes main chamber produce pressure and valve body import internal pressure formation balance, by self gravitation or spring force, main valve is closed very soon.

The 2nd, the media filtration function, medium enters the solid of rotation inlet passage by filter screen, discharges from outlet passage.

The 3rd, throttling function, because of on solid of rotation and valve body wall separately, corresponding semicircle orifice being arranged, when two semicircle orifices face, the flow maximum, flow reduces when skew, reaches the effect of throttling.

Four, regulate the function of flow, because of solid of rotation can rotate at body cavity, at this moment, when the relative timing of two inlet passages, the flow maximum of medium then, the position relativity shift of two inlet passages when angle of solid of rotation rotation, then flow reduces thereupon, even is zero.

Five, the flushing and the function of other medium washing filter screen voluntarily, valve in use, medium and impurity can reach filtration by filter screen simultaneously, make impurity can not enter spool, use one by one the section time after, because impurity blocks filter screen, cause valve flow to reduce, manual handle driven rotary body revolved and turn 90 degrees this moment, opened spool, MEDIA FLOW reaches the effect of flushing voluntarily to filter screen.The congestion situations of filter screen can be observed by observation panel with handle to the dextrorotation turnback, if filter screen blocks, can screw off the peeping lens outer nut, takes off peeping lens, with other medium washing filter screen, perhaps directly takes off the filter screen flushing.If do not allow the medium outflow, can allow solid of rotation be rotated counterclockwise 90 degree, also can utilize other medium flushing.If solenoid valve action is malfunctioning, just can be under the working position to clockwise or be rotated counterclockwise miter angle, the passage of solid of rotation all can not be communicated with the valve body import, spool and filter screen all can be pulled down and keep in repair this moment, and utilize other passage, and medium is passed through, valve carries out work as usual.

Six, utilize throttle orifice between solid of rotation and the valve body, when being rotated, the main valve gap is reduced, reach the compensate for wear function.

Seven, can be in harmonious proportion actuation time adjustable for dielectric viscosity Applicable scope, if when dielectric viscosity is big, then the throttle orifice between solid of rotation and the valve body is opened greatly, if dielectric viscosity than hour, then throttle orifice is opened for a short time, makes the valve proper functioning, actuation time is adjustable also as above-mentioned.No matter any medium, hold big main valve when throttle orifice and can occur opening slowly, when reaching maximum, throttle orifice can make main valve stop to open again, and throttle orifice is held little main valve and can be opened soon, and reaching, the most not closed condition can appear in hour main valve.

The utility model compact structure, multi-purpose valve, flexible to operation, can adapt to the different medium of viscosity, the effect with compensate for wear, maintenance is convenient, saves several manually operated valves and bypass duct.This valve is widely used in that textile printing and dyeing, petrochemical industry, iron and steel metallurgy, food are brewageed, health care, plastic, rubber, light industry and machinery, electron and electrician and national defence sophisticated industry, is used for the automatic control of water, air, steam, freon, oil and other medium pipeline.
