The air line structure of air storage type pneumatic actuating mechanism is characterized in that the input end of a filter reducing valve is connected with an air source and connected with the air input end of an air storage tank by a one-way valve, and the output end is respectively connected with the end P of a localizer and the end P of a two-position three-way solenoid valve; the end A of the localizer is connected with the end P of a pneumatic control valve A, and the end B is connected with the end vof the pneumatic control valve B; the end A of the pneumatic control valve A is connected with an air chamber A of a piston; the end A of the pneumatic control valve A is connected with an air chamber B of the piston (8); a signal end is in parallel connection with the signal end of the pneumatic control valve A and connected with the end A of the two-position three-way solenoid valve; the output end of the air storage tank is connected with the end R of the pneumatic control valve A; a pressure relay is installed in front of the end P of the solenoid valve. Through the change of air line, the air pressure in the air storage tank can be improved under the condition of not improving the original air pressure, the equipment cost can be reduced; furthermore, as the pressure is increased, the response time of piston rod under sudden failure is also shortened and the use performance is enhanced.
Description
Technical field
The utility model relates to a kind of air storing type pneumatic actuator, particularly a kind of gas circuit structure of air storing type pneumatic actuator.
Background technique
At present, in some particular field in fields such as electric power, oil and chemical industry, the valve that a lot of industrial and minerals require pneumatic control is under the situation in source of dying, and valve can be closed rapidly.General situation installs big gas holder exactly additional, and cost just increases greatly like this.
Summary of the invention
In view of market demand, the utility model provides a kind of gas circuit structure of air storing type pneumatic actuator, the technological scheme of being taked is: a kind of gas circuit structure of air storing type pneumatic actuator, comprise one-way valve, filtering pressure reducing valve, positioning work piece, pressure relay, the two-bit triplet solenoid valve, Pneumatic valve B, Pneumatic valve A, piston and gas holder, it is characterized in that: described filtering pressure reducing valve input end links to each other with source of the gas and links to each other with the inlet end of gas holder through one-way valve, output terminal respectively with the P of positioning work piece end, the P end of two-bit triplet solenoid valve links to each other, the A end of positioning work piece links to each other with the P end of Pneumatic valve A, the B end links to each other with the P end of Pneumatic valve B, the A end of Pneumatic valve A links to each other with the A air chamber of piston, the A end of Pneumatic valve B links to each other with the B air chamber of piston (8), the signal end of signal end and Pneumatic valve A also connects and connects the A end of two-bit triplet solenoid valve, the output terminal of gas holder links to each other with the R end of Pneumatic valve A, setting pressure relay before the P of solenoid valve end.
The beneficial effects of the utility model are: the change by gas circuit makes gas holder increase at the following jar internal air pressure of the condition that does not improve source of the gas air pressure, reduced equipment cost, and, strengthen to some extent on the usability because the response time of piston rod when catastrophic failure has also been shortened in the pressure increase.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Adopt KA-8 one-way valve 1, the AW-2000 filtering pressure reducing valve 2 of SMC, the 6DR521-0NG positioning work piece 3 of FISHER, the IS3000-02 pressure relay 4 of SMC, the SY200 two-bit triplet solenoid valve 5 of SMC and VTA315-02 Pneumatic valve A7, the B6 of two SMC.
As shown in Figure 1, filtering pressure reducing valve 2 input ends link to each other with source of the gas and link to each other through the inlet end of one-way valve 1 with gas holder 9, output terminal respectively with the P of positioning work piece 3 end, the P end of two-bit triplet solenoid valve 5 links to each other, the A end of positioning work piece 3 links to each other with the P end of Pneumatic valve A7, the B end links to each other with the P end of Pneumatic valve B6, the A end of Pneumatic valve A7 links to each other with the A air chamber of piston 8, the A end of Pneumatic valve B6 links to each other with the B air chamber of piston 8, the signal end of signal end and Pneumatic valve A7 also connects and connects the A end of two-bit triplet solenoid valve 5, the output terminal of gas holder 9 links to each other with the R end of Pneumatic valve A7, setting pressure relay 4 before the P of solenoid valve 5 end.
Gas circuit principle
1, when actuator's proper functioning, gas is held A chamber and the B chamber that enters piston 8 by the P of the I position of filtering pressure reducing valve 2, solenoid valve 5, positioning work piece 3, two-position three way Pneumatic valve A7, B6, carries out the regulating action of valve; Simultaneously, gas enters gas holder 9 by one-way valve.
2, when bleed pressure drops to a certain degree, by 5 outages of pressure relay 4 control electromagnetic valve, solenoid valve 5 commutations (becoming the I position) by II, gas by solenoid valve 5 is broken, thereby the control source of the gas of two-position three way Pneumatic valve A7, B6 is broken, two-position three way Pneumatic valve A7, B6 commutate (becoming the II position) by I.At this moment, because air pressure equals source of the gas air pressure in the gas holder 9, be higher than operating air pressure in the gas circuit, make the II position P end of gas by two-position three way Pneumatic valve A7 in the gas holder 9 enter the A chamber of piston 8, gas in the B chamber is discharged by the II position R end of two-position three way Pneumatic valve B6, piston rod is shot out, thereby made valve closes, can realize rapid closing function.
When 3, gas circuit is lost the gas dead electricity simultaneously, because dead electricity, solenoid valve 5 will place the I position, then A7, B6 will place the II position owing to losing first air guide signal, then since in the gas holder 9 air pressure equal source of the gas air pressure and be higher than operating air pressure in the gas circuit, so the P end of the gas in the gas holder 9 by two-position three way Pneumatic valve A7 II position enters the A chamber of piston 8, the gas in the B chamber is discharged by the R end of two-position three way Pneumatic valve B6 II position, die thereby reach valve, finish the effect of closing rapidly.
Owing to have a constant pressure drop with gas circuit in the gas holder 9, just make piston rod in the piston 8 to stretch out action more rapid, reach the action of corresponding failure more timely.Same existence owing to pressure drop just makes can select a less specification to save cost when selecting the design gas holder.
