A piece pressure regulation bar, it is characterised in that described pressure regulation bar includes shaft and rod handle, the shaft of the pressure regulation bar is located in influent stream chamber
And with diameter greater than through-hole diameter, rod handle is then connected through through hole with capping, rod handle is less than through-hole diameter, and described influent stream intracavity sets
There is a chute, above-mentioned shaft spacing can slide in chute cathetus, the pressurized backward elastomeric element side of the capping promotes and will be logical
Hole is opened, and flow gap is formed between shaft and the end face of through hole to be used to adjust flow.
The flexible adjustment device for elastomeric element is provided with described outflow lumen, changes envelope by flexible adjustment device
The size of the closure power of lid.
Described flexible adjustment device includes a valve gap, and described valve gap is connected with valve body screw thread, is provided with the outside of valve gap
Adjusting knob, described elastomeric element are located between valve gap and capping, change elastic by the position relationship of valve gap and valve body
The initial yield intensity of part.
Connecting seat is coaxially provided with described capping, connecting seat is provided with interior annular for positioning elastic part, connecting seat
On be additionally provided with screwed hole, above-mentioned rod handle is threadedly coupled through capping and with the screwed hole of connecting seat.
Described capping rear portion is provided with sealing ring, and described sealing ring is by the airtight space residing for elastomeric element.
Described influent stream chamber is connected with an electromagnetic valve.
Compared with prior art, the pressure regulation bar of the device can with capping linkage, flow gap when capping is opened directly just
Can be formed, pressure regulation is accurate.Pressure regulation bar does not have any attached parts, therefore the probability for damaging is little, long service life.
