Description
Technical field
The present invention relates to valve class technical field, particularly a kind of metal pressure regulator valve.
Background technique
Pressure regulator valve is the pneumatic element of the stable output of a kind of adjustable pressure, applies comparatively extensively, and by people's know, with common, its principle is by pressurized air is carried out to throttling adjusting, to ensure the stable gas pressure of output terminal.The structure of current known pressure regulator valve conventionally as shown in Figure 1, comprise valve body 100, the valve gap 200 being connected with valve body 100 upper ends, the tightening cover 600 being connected with valve body 100 lower ends, and be located at the diaphragm 300 between valve body 100 and valve gap 200, between described valve body 100 and diaphragm 300, coordinate and form upper chamber 400, between described valve body 100 and tightening cover 600, coordinate and form lower chambers 700, on described valve body 100, be respectively equipped with the suction port 110 being communicated with lower chambers 700, the air outlet 120 being communicated with upper chamber 400, and be communicated with the pore of described upper chamber 400 and lower chambers 700, described valve gap 200 is provided with adjusting handle 210, described adjusting handle 210 is provided with adjusting screw rod 220, in described valve gap 200, be provided with and the corresponding regulating nut 230 of adjusting screw rod 220, between described regulating nut 230 and diaphragm 300, be provided with definite value spring 500, between described valve body 100 and tightening cover 600, be provided with the spool 800 being equipped with pore, on described spool 800, moulding is provided with valve rod 810, the top of described valve rod 810 is passed described pore and is offseted and coordinate with diaphragm 300, between described spool 800 and tightening cover 600, be provided with balance spring 900.Its working principle is: when work, pressurized gas enters lower chambers 700 through suction port 110, in the time of turn adjusting handle 210, compress definite value spring 500 by regulating nut 230, after definite value spring 500 is stressed, compress diaphragm 300, under the effect of definite value spring 500, there is deformation the valve rod 810 of conflicting in diaphragm 300, make valve rod 810 be with movable valve plug 800 to move down, make upper chamber 400, between pore and lower chambers 700, form path, by the gap length between regulating spool 800 and pore, change the flow velocity of gas flow through pore, and then the pressure size of change gas output, reach the effect of air pressure adjustment.
But above-mentioned pressure regulator valve is unreasonable because structure arranges, cause existing following defect: first, owing in valve body 100 bottoms, locking cap 600 being set, cause structure setting comparatively complicated, and because locking cap 600 is positioned at the outside of valve body 100, cause valve body 100 sealings lower; The second, due to the setting that is formed in one of spool 800 and valve rod 810, when installation, spool 800 is arranged between locking cap 600 and valve body 100, cause taking installing space larger, make the volume of pressure regulator valve larger; The 3rd, due to spool 800 and the one-body molded setting of valve rod 810, when work, spool 800 is synchronized with the movement with valve rod 810, and valve rod 810 is that axial motion occurs under the conflict of diaphragm 300, for the coaxality that ensures that valve rod 810 moves, therefore distance is less between general valve rod 810 and pore inwall, in the time that valve rod 810 is frequently subject to diaphragm 300 and compresses, make valve rod 810 easily and between pore inwall produce and rub, cause having certain drag effect between valve rod 810 and valve body 100, thereby affect the sensitivity of air pressure adjustment.
Summary of the invention
