Abstract
The utility model relates to a structure belonging to hydraulic pressure and pneumatic technical field, which is characterized in that the utility model provides a ceramic spool reversing valve. One of the spools is a fixed chip, the other one of the spools is a movable chip, and the movable chip is rotated by the control mandrel to change the channel of the gas. The utility model has the advantages of inverting, good sealing performance, long life, preventing the phenomenon of running, emitting and leaking of the gas or liquid, and saving energy. The utility model is widely used in the controlling of the gas or fluid path in a plurality of fields such as industry and agriculture and national defense.
Description
Hydraulic pressure and pneumatics field under the utility model.
In various FLUID TRANSPORTATION, control system such as the gas of industrial application, liquid, usually to adopt various valves to control various fluids and end, commutate or change the flow size.But in the pipeline transporting system in the present industrial field, defective such as all tight because of various valves controls, poor sealing performance, working life are short makes liquid, gas loss bigger.In some key areas, cause bigger loss to country, even bring the injury of national wealth and life.Therefore in the pipeline transporting system, selecting for use of control valve is particularly important.
The purpose of this utility model is to provide a kind of sealing chip of being made by stupalith, its good seal performance, the selector valve that the life-span is long.
The utility model is made of valve body (loam cake, base), spool, handle.As shown in the figure: Fig. 1 is a structural drawing, and Fig. 2 is a sectional view.1 loam cake among Fig. 1,2 sealing gaskets, 3 nuts, 4 mandrels, 5 fixing pins, 6 handles, 7 fixed chips, 8 movable chips, 9 bases, four screws of 10 fastening seats and loam cake, 11 springs.Wherein, spool fixed chip 7 is fastened in the loam cake by sealer, and movable chip 8 is installed in the base 9, under the chip spring is arranged.Upper and lower valve core is adjacent to, and loam cake and base are fastening by four screws 10, and two locating studs 5 are arranged on the loam cake 1, and handle 6 is by mandrel 4 rotatable movable chips 8.
The utility model is the ceramic valve core selector valve, and it is that mandrel is passed in the rectangle blind hole of bonnet and fixed chip insertion activity chip.By handle rotation activity chip.After pressurized air entered from inlet hole, when handle was in position shown in Figure 1, pressurized air entered the circular arc passage of movable chip through the last hole of fixed chip, send from the left end air outlet hole.When handle rotates 60 ° (handle is in symmetrical position shown in Figure 1), drive activity chip rotates 60 °, make pressurized air enter the back and send from the right-hand member air outlet hole by movable chip circular arc passage, thereby make outer bindiny mechanism carry out about (or advance and retreat) move.When connection actuator need stop in the centre, handle can be got back to zero-bit (symmetry center line position shown in Figure 1).So just can reach the function of selector valve.
Fixed chip 7 described in the utility model and movable chip 8 are made by special ceramic material, and two surface of contact are made by abrasive machining.Three holes perpendicular to the plane are arranged on the fixed chip, one is inlet hole, and two is air outlet hole in addition, and two arc grooves different in size are arranged on the movable chip, elongated slot can be connected and fixed the inlet hole and the air outlet hole of chip, and at this moment the position of short groove is just connecting another air outlet hole and exhaust port.Can play scavenging action.Gas or liquid are to enter fixed chip one air outlet hole from the fixed chip import by movable chip circular arc guiding gutter.If handle 6 is rotated about 60 °.Gas or liquid can be from another air outlet hole outputs of fixed chip.Thereby reach the purpose of commutation.The flow of gas or liquid can be regulated by the position of handle 6.What in fact regulate is the area of contact of air outlet hole and guiding gutter.Be provided with pressure-resistant seal pad 2 in the valve body and can guarantee that valve does not have leakage.
Spool of the present utility model, one is fixed chip, and one is movable chip, and movable chip is to be rotated it and made the gas and changing passage by the control mandrel, thereby reaches the purpose of commutation.
Advantage of the present utility model is good seal performance, and the life-span is long, has prevented " run, emit, leak " phenomenon of gas or liquid, has saved the energy.
