A kind of air compressor machine direct proportion valve described in the utility model, including valve body, the bonnet being fixedly connected with the valve body, valve body
Provided with air inlet, exhaust outlet and valve port, air inlet is connected with exhaust outlet by valve port, and pressure regulation group is provided between valve body and bonnet
Part, regulation component include look nut, screw press, pressure spring, gland, pressure head, diaphragm and valve element, look nut and bonnet
Rotation stop coordinates, and screw press is threadedly coupled with look nut, and the upper end of screw press through bonnet and is connected with adjusting knob, presses
Lid, diaphragm are pressed between bonnet and valve body from top to bottom, and pressure head pressure is located between gland and diaphragm, and the top of valve element is worn successively
Cross diaphragm and pressure head and be connected with clamp nut, the bottom of adjusting screw rod is axially abutted with clamp nut, and pressure spring is supported and is located at
Between pressure head and look nut, the bottom of valve element forms the spherical plug coordinated with sealing valve port.
Further, gas deflation assembly is additionally provided with valve body, gas deflation assembly includes hollow Exhaust screw and exhaust nut, row
Gas screw is vented between nut and valve body located at the middle part of exhaust nut and is provided with pad.
Further, the bottom of pressure head is provided with the bulge loop for being used for compressing diaphragm.
Further, bonnet is connected with valve body screw thread.
The utility model has the beneficial effect that：The utility model sets spherical plug in governor motion, by increasing capacitance it is possible to increase closure
Sealing, prevent valve inner air pressure reveal, extend direct proportion valve service life.The air inflow of the utility model air inlet
Rise, to diaphragm build-up of pressure, drive pressure head to compress pressure spring, it is spherical stifled so as to be moved up with the spherical plug on movable valve plug
Head departs from sealing with valve port and coordinated, and now air inlet is connected with exhaust outlet, air pressure that can in time in exits valve body.This practicality
New structure advantages of simple, sealing is high, can prevent air pressure from revealing, extend the service life of direct proportion valve.
