Abstract
The utility model relates to a guide control valve, which is composed of a diaphragm, a water inlet, a water outlet, a switch, a valve body, etc. The utility model is characterized in that a guide outlet is in the form of a straight-through pipeline, a stepper motor or a reversible motor controlled by a microcomputer is connected with a speed changer, and the speed changer is also connected with the ceramic sheet switch provided with a connection shaft. The ceramic sheet switch is composed of an upper ceramic sheet, a lower ceramic sheet and the connecting shaft, wherein, the upper and the lower ceramic sheets are respectively provided with two sector-shaped holes, and the rest parts of the upper and the lower ceramic sheets are solid. With the guide control valve provided by the utility model, the clogging problem of the device is completely eliminated, and reliability and stability are enhanced. Guide holes are opened or closed by the high-precision ceramic seal sheets, the utility model has the advantages of tight seal, flexible closing, small control power and no need of maintenance, and after the utility model is controlled, the stable state of opening or closing can be kept without power supply.
Description
The utility model relates to a kind of pilot-actuated valve that is used to control fluid.
Be widely used at present after pilot-actuated valve in the control of liquid such as tap water works long hours, easily stop up; Also be difficult for after control, keeping its stable working state.
The purpose of this utility model is to provide a kind of pilot-actuated valve, is made of diaphragm, water intake, water outlet, switch, valve body etc., and it is characterized in that: first export mouth is the direct piping form; The stepper motor of microcomputerized control or reversible electric machine connect speed changer, and speed changer connects the ceramic plate switch that has coupling shaft again.The ceramic plate switch is made up of last ceramic plate, following ceramic plate and coupling shaft, and upper and lower ceramic plate respectively has two fan shaped boreholes, and all the other are entity part.Make reliability of the present utility model, stability strengthen greatly, can not stop up.Improved the defective of prior art
The purpose of this utility model also realizes as follows: two pilot holes on the diaphragm, aperture are 2 millimeters to 8 millimeters, and diaphragm thickness is 0.4 centimetre.The aperture of elder generation's export mouth is 7 to 8 millimeters.
The pilot-actuated valve that adopts the utility model to provide has thoroughly been eliminated the blockage problem of installing, and reliability and stability strengthen greatly.Pilot hole is opened or closed to the high-precision ceramic diaphragm seal, and sealing is tight, closes flexibly.Power controlling is little, need not power after the control just to keep the steady state that opens or closes, need not holding power.
Below in conjunction with accompanying drawing the utility model is done further narration.
Fig. 1 master of the present utility model looks sectional view.
Fig. 2 is the plan view of ceramic plate switch of the present utility model.
With reference to Fig. 1, valve body 13 is an oblate object, and an end has water intake 1.Diaphragm elder generation introducing port 14 is pushed down and blocked to diaphragm 2.Place a spring 3 between diaphragm top and the loam cake 12 and push down diaphragm.Elder generation introducing port 10 tops have by the ceramic plate switch that descends ceramic plate 4, last ceramic plate 5 and the ceramic plate coupling shaft 8 that is connected ceramic magnetic plate to constitute.Stepper motor 6 in the ceramic plate switch control box body 9 connects speed changer 7, and speed changer connects ceramic plate coupling shaft 8.Water outlet 15 is communicated with first export mouth 11, and first export mouth is communicated with first introducing port by the ceramic plate switch, and first introducing port 10 is communicated with diaphragm elder generation introducing port 14, and diaphragm elder generation introducing port is communicated with water intake.
With reference to Fig. 2, ceramic plate has two fan shaped boreholes 17,18 on the disc, and all the other are entity part 16, the ceramic plate coupling shaft 8 of ceramic plate in the connection, and ceramic plate also has two fan shaped boreholes (in Fig. 2, dotting) under the disc.
When the fan shaped borehole of last ceramic plate forwards (as shown in Figure 2) when overlapping the position with the fan shaped borehole of following ceramic plate to, elder generation's export mouth is communicated with first introducing port by the fan shaped borehole of upper and lower ceramic plate, liquid such as water just can pass through water intake, diaphragm elder generation introducing port, diaphragm, first introducing port successively, descend the fan shaped borehole of ceramic plate, fan shaped borehole, first export mouth, the water outlet of last ceramic plate, the pilot-actuated valve of flowing through.When last ceramic plate turns over 90 when spending, when the entity part 16 of last ceramic plate forwards and blocks down the fan shaped borehole of ceramic plate to, the connected sum that just can cut off first export mouth and the first introducing port liquid such as water of pilot valve of flowing through.Stepper motor drives speed changer, and speed changer drives the ceramic plate coupling shaft, and the ceramic plate coupling shaft drives goes up the ceramic plate rotation.
