Description
Technical field
The present invention relates to valve class technical field, particularly to a kind of metal pressure regulator valve.
Background technology
Pressure regulator valve is a kind of pneumatic element regulating stable gas pressure output, applies relatively broad, is known with often
Seeing, its principle is by compressed air is carried out flow restriction control, to ensure the stable gas pressure of output.Currently known pressure regulator valve
Structure generally as it is shown in figure 1, include valve gap 200 and valve body 100 lower end that valve body 100 is connected with valve body 100 upper end
The tightening cover 600 being connected and the diaphragm 300 being located between valve body 100 and valve gap 200, described valve body 100 and diaphragm
Cooperatively form upper chamber 400 between 300, between described valve body 100 and tightening cover 600, cooperatively form lower chambers 700, described valve body
Gas outlet 120 and connection institute that the air inlet 110 connected with lower chambers 700 connects it is respectively equipped with upper chamber 400 on 100
Stating upper chamber 400 and the pore of lower chambers 700, described valve gap 200 is provided with adjusting handle 210, and described adjusting handle 210 sets
There is adjusting screw rod 220, in described valve gap 200, be provided with regulating nut 230 corresponding with adjusting screw rod 220, described regulating nut 230
And it is provided with definite value spring 500 between diaphragm 300, is provided with, between described valve body 100 and tightening cover 600, the valve being equipped with pore
Core 800, on described spool 800 shaping be provided with valve rod 810, the top of described valve rod 810 through described pore and with diaphragm 300 phase
Support and coordinate, between described spool 800 and tightening cover 600, be provided with balancing spring 900.Its operation principle is: during work, compressed gas
Enter lower chambers 700 through air inlet 110, when turn adjusting handle 210, compress definite value spring 500 by regulating nut 230,
Compressing diaphragm 300 after definite value spring 500 stress, diaphragm 300 deforms upon and conflicts valve rod under the effect of definite value spring 500
810, make valve rod 810 band movable valve plug 800 move down, make to be formed between upper chamber 400, pore and lower chambers 700 path, by regulation
Gap length between spool 800 and pore, changes gas and flows through the flow velocity of pore, and then the pressure changing gas output is big
Little, reach the effect of air pressure adjustment.
But, above-mentioned pressure regulator valve is unreasonable because structure is arranged, and causes existing following defect: first, due at valve body 100 end
Portion arranges locking cap 600, causes structure to arrange complex, and owing to locking cap 600 is positioned at the outside of valve body 100, causes
Valve body 100 sealing is relatively low；Second, owing to spool 800 and valve rod 810 are formed in one setting, during installation, spool 800 is arranged
Between locking cap 600 and valve body 100, cause taking installing space bigger so that the volume of pressure regulator valve is bigger；3rd, due to
Spool 800 and the one-body molded setting of valve rod 810, during work, spool 800 is synchronized with the movement with valve rod 810, and valve rod 810 is at diaphragm
Axially-movable is there is under the conflict of 300, for ensureing the axiality of valve rod 810 motion, thus general between valve rod 810 and pore inwall
Distance is less, when valve rod 810 is frequently compressed by diaphragm 300 so that valve rod 810 easily and produces friction between pore inwall,
Cause existing between valve rod 810 and valve body 100 certain drag effect, thus affect the sensitivity of air pressure adjustment.
Summary of the invention
