Adopt technique scheme, be provided with rational in infrastructure, and simple like this.
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Description of drawings
Fig. 1 is the utility model embodiment's a principle schematic.
Embodiment
A kind of valve atmospheric control as shown in Figure 1, include with the filtering pressure reducing valve 1 of main air supply pipe interlock, solenoid valve 2, limit switch 3 and with pneumatic 4 of the spring reset of cut-off valve interlock; Solenoid valve 2 is provided with two at least, 3 of filtering pressure reducing valve 1 and limit switches are provided with gas gas positioning work piece 5, each solenoid valve 2 is set up in parallel and series connection mutually, one of them solenoid valve 2 is connected with gas gas positioning work piece 5, constitute the transmission of signal, the pressure regulator valve 6 that is respectively equipped with adjustable pressure and ends between each solenoid valve 2 and the filtering pressure reducing valve 1.In the technique scheme, solenoid valve 2 is provided with two, includes solenoid valve a21 and solenoid valve b22; When cut-off valve need cut out and open, main air supply pipe is crossed Pneumatic pipe cleaner at pressure regulator valve 6 places at filtering pressure reducing valve 1 and direct solenoid valve 2 places that are connected with gas gas positioning work piece 5, solenoid valve a21 and solenoid valve b22, all must not, the signal that gas gas positioning work piece receives signal source will be zero, and this moment, pneumatic head made valve keep the complete shut-down position under the effect of spring.If with solenoid valve a21 dead electricity, solenoid valve b22 gets, and the pressure regulator valve pressure that will be connected with solenoid valve b22 is located at the fully open position signal simultaneously, gas gas positioning work piece 5 will receive the standard-sized sheet signal pressure at this moment, under the effect of power gas source, client's spring makes spring chamber and no spring chamber reach balance, and fully open position finishes.Under the effect of pneumatic head, limit switch feeds back the standard-sized sheet contact signal simultaneously.When cut-off valve such as need are opened (promptly half-open) midway, solenoid valve a21 gets, solenoid valve b22 dead electricity, and the pressure regulator valve that is connected with solenoid valve a21, configure appropriate signal pressure, this signal pressure, can obtain different neutral positions, this moment, signal pressure was by solenoid valve a21, solenoid valve b22 arrives gas gas fixture signal mouth, after positioning work piece receives coherent signal, make power gas source enter the no spring chamber of pneumatic head, drive valve event, this action arrives certain when a bit, and positioning work piece makes spring terminal and no spring terminal reach balance, pneumatic head just keeps this position, constitutes stopping over of cut-off valve.Be applicable to special operation condition, increased the versatility of this system.
In the utility model embodiment, solenoid valve a21, solenoid valve b22 and gas gas positioning work piece 5 connect and compose the signal transmission, and solenoid valve a21 connects with solenoid valve b22.Solenoid valve a21 and solenoid valve b22 include working hole 23, suction port 24 and relief opening 25 respectively, the working hole 23 of described solenoid valve b22 is connected with gas gas positioning work piece 5, the working hole 23 of solenoid valve a21 is connected with the relief opening 25 of solenoid valve b22, and the suction port 24 of solenoid valve a21 and the suction port 24 of solenoid valve b22 are connected with pressure regulator valve 6 independently respectively.
At above-mentioned two groups of solenoid valves, its working principle is as follows: gas source (power gas source) enters filtering pressure reducing valve 1, arrives pressure regulator valve 6 then and arrives gas gas positioning work piece power gas source mouth simultaneously, prepares in order to drive pneumatic head.Pressure regulator valve 6 is set different signal pressures respectively, and what wherein solenoid valve b22 was connected is standard-sized sheet control and complete shut-down control; What be connected with solenoid valve a21 is the control in neutral position.Solenoid valve a21 and solenoid valve b22 are the conveyings of control pressure signal.When gas gas positioning work piece receives different signal pressures, will make power gas arrive the no spring chamber of pneumatic head, and drive pneumatic piston, and make pneumatic spring chamber and no spring chamber reach balance, this moment, pneumatic head quit work.Limit switch only is during in work, to give control room feedback contact signal at pneumatic head.The realization of complete shut-down position: solenoid valve a21, solenoid valve b22 all must not be electric, and the signal pressure that gas gas positioning work piece receives is " zero ", and will be that valve is in the complete shut-down position this moment under spring action.Fully open position is realized: solenoid valve b22 gets electric, solenoid valve a21 dead electricity, and the fully open position signal pressure will arrive gas gas fixture signal receiving port from solenoid valve b22, gas gas positioning work piece enters the no spring chamber of pneumatic head with power gas, pressure spring makes valve closing, reaches the pressure at two ends balance.The realization that pauses in the neutral position: solenoid valve a21 energising, solenoid valve b22 dead electricity, signal pressure arrives pressure regulator valve 6 from gas source, the pressure regulator valve that is connected with solenoid valve a21, set convenient pressure (setting according to the neutral position needs), signal pressure arrives solenoid valve a21, solenoid valve a21 get electric after, commutation is with suction port and working hole conducting, solenoid valve b22 relief opening then, by solenoid valve b22 relief opening, working hole arrives fixture signal reception place.After positioning work piece received neutral position signal number, notice power gas made pressure spring to the no spring chamber air feed of pneumatic head, reaches pneumatic spring chamber and reaches balance with no spring chamber.Pause in the realization neutral position.
