Supplement.
The course of work and operation principle of the present invention：Air source is connected in gas source air inlet, outlet interface and switch are controlled
The entrance connection of valve processed, the outlet of intake interface and switching control pilot is connected, and gas outlet is connect with air hoist, opens gas
Source, gas enter control air cavity, but since under normality of the present invention, plug piston exists from gas source air inlet into rear portion gas
It is in contact under the promotion of piston spring with gas circuit plug and blocks the air inlet of venting channels, gas cannot be through controlling air cavity at this time
Enter in outlet gas circuit, gas at this time enters switching control pilot through outlet interface, from switching control pilot control whether to
Air hoist is supplied to start air hoist, and when needing to supply to air hoist, switching control pilot control is opened, at this time gas
Air hoist is output to from gas outlet after intake interface entrance, air hoist starts；
Control valve is turned off the switch at this time, is turned pressure regulating cover to adjust active force of the valve core spring to spool, is made spool both sides
Suffered power is balanced, and in the case where the gas in ignoring air hoist is to the active force of plug piston, makes valve core spring
It is equal to piston spring to the thrust of spool to the thrust of plug piston, air source air pressure in the pressure and air hoist of plug piston
Gas to the sum of active force of spool (below by piston spring to the thrust of plug piston, air source air pressure to plug piston
Gas in pressure and air hoist is referred to as the sum of three power to the sum of active force of spool) when reach balance.
After the completion of adjustment, after switching control pilot is closed, when air hoist generates gas leakage, then the balance of spool is lost,
I.e. valve core spring is more than the thrust of spool the sum of three power, and valve core spring pushes spool movement, by means of valve rod by plug piston
It pushes open, at this point, plug piston forms access with gas circuit plug, source gas is entered out by the access of formation through venting channels
To air hoist make-up gas after gas gas circuit, air hoist is made to achieve the effect that constant pressure.
After make-up gas, after valve core spring is equal to the sum of three power to the thrust of spool, spool automatically resets, plug piston
Gas circuit plug is blocked；If generate gas leakage again, the present invention can repeat the above process the supplement for carrying out gas automatically.
If air source air pressure occur reduces or suddenly disappear, gas can flow into stepped hole from the cylinder of air hoist rapidly,
The aperture of diameter holes is blocked to block gas circuit by the stifled ball in impact stepped hole, avoids the gas loss in air hoist,
It ensure that the stability of work, this is because when air source air pressure is reduced or suddenly disappeared, throughput is bigger, therefore stifled ball will
Gas circuit blocks, if but air hoist generate gas leakage, airflow direction and air source air pressure drop during gas leakage are generated due to air hoist
Low or when suddenly disappearing airflow direction is opposite, therefore stifled ball will not block gas circuit, so as to fulfill gas is smoothly supplemented
Body.
Above-described embodiment is the preferable embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, other any Spirit Essences without departing from the present invention with made under principle change, modification, replacement, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
