The space of 33 lower section of plug is connected to transformation chamber 8.The lower end of pressurize piston 32 is contacted across batching pig 33 with air draft current limliting plug 34, is used
In the metering hole being opened and closed in air draft current limliting plug 34, metering hole moves up and down realization opening and closing by pressurize piston 32.
It is tightly connected, and is both provided with up and down between pressurize piston 32, batching pig 33 and air draft current limliting plug 34 and shell
Two seals slot, is equipped with sealing joint strip in seal groove.
The outside of security personnel's spring 31 is cased with an adjustment bolt 38, passes through between adjustment bolt 38 and the shell for component 30 of ensuring public security
It is threadedly coupled, is threaded hole 39 in the top of adjustment bolt 38, operation threaded hole 39 is the initial of adjustable security personnel's spring 31
Pressure.
The course of work of security personnel's component 30 is as follows：
Cylinder 40 is in pressurization since the space between 32 lower end of pressurize piston and batching pig 33 passes through with equivalent pressure cavity 9
Upper vent hole 35 is connected, and pressure is not yet set up, and pressurize piston 32 remains shown in Fig. 1 under the action of ensuring public security spring 31
State, the bottom end of pressurize piston 32 is resisted against on air draft current limliting plug 34, and the metering hole on air draft current limliting plug 34 is in closed
State.
As pressure improves in cylinder 40, pressure improves in equivalent pressure cavity 9, and 32 times end pressures of pressurize piston also improve, to
Push pressurize piston 32 to move up, the metering hole on air draft current limliting plug 34 opened, due to lower venthole 36 by transformation chamber 8 be isolated
The space connection of 33 lower section of plug, to which the transformation chamber 9 in lower valve body 2 is connected to ambient atmosphere, the pressure drop in transformation chamber 9
Low, drain valve is started to work.
When air compressor is stopped, 32 times cylinder 40, equivalent pressure cavity 9 and pressurize piston end pressures will reduce, pressurize
Piston 32 moves down the metering hole closed on air draft current limliting plug 34, and cylinder drain valve is stopped.It can by adjusting adjustment bolt 38
Change the pressure that high ferro cylinder automatic drain valve starts and is stopped, reaches the purpose of pressurize.
When not having water in cylinder, water collection chamber 7 is identical with the pressure in equivalent pressure cavity 9, and the air pressure in transformation chamber 8 depends on air inlet
The size of 34 upper limit discharge orifice of current limliting plug 20 and air draft current limliting plug, if the air pressure in the identical transformation chamber of holes size 8 is equal to water collection chamber 7
The half of pressure.
The course of work of drain valve is as follows：
Before drain valve work, the sum of the top power of main spring 6 and the air pressure in transformation chamber 8 are except the gas in confrontation equivalent pressure cavity 9
Also have except pressure and overcomes frictional resistance and ensure that draining valve port 15 remains off.
It is pressurized to cylinder 40, when water level rises in water collection chamber 7, floating ball 14 rises with water level, and moves closer to and block
Metering hole 25 on air inlet current limliting plug 20, the air pressure in transformation chamber 8 will be by lower venthole 36 and air draft current limliting plug 34
Metering hole is laid down, and the top power of main spring 6 is not enough to the pressure in confrontation equivalent pressure cavity 9 at this time, i.e. pressure in equivalent pressure cavity 9 is more than master
The top power of spring 6 and the sum of the pressure in transformation chamber 8, Elastic forming board 3 will drive manipulation bar assembly 13 to move down, and then open
The draining valve port 15 of bottom realizes draining.
It controls air compressor to shut down, when water level decreasing in water collection chamber 7, floating ball 14 falls and leaves air inlet current limliting plug 20
On metering hole, the air pressure in transformation chamber 8 will increase, and the top power of main spring 6 is enough with the sum of the air pressure in transformation chamber 8 at this time
The pressure in equivalent pressure cavity 9 is fought, Elastic forming board 3 will drive manipulation bar assembly 13 to move up, and then it is real to close draining valve port 15
Now stop draining.
The drain valve is provided with water information by small-sized floating ball 14, and draining valve port 15 as powered using compressed air opens
It closes, to increase auxiliary security personnel's link for high ferro braking system, especially can ensure braking when wind regime purifier fails
System worked well, to make up the deficiencies in the prior art.
As described above, the plan content in conjunction with given by attached drawing, can derive similar technical solution.In every case it is not de-
Content from technical solution of the present invention, according to the technical essence of the invention to made by above example it is any it is simple modification, etc.
With variation and modification, in the range of still falling within technical solution of the present invention.
