Description
Technical field
The present invention relates to valve class technical field, particularly a kind of mini filtering pressure reducing valve.
Background technique
Filtering pressure reducing valve is to set up filter element on the basis of reduction valve, guarantee when output pressure is stable also source of the gas to be carried out to filtration treatment, impurity such as the oil in removal pressurized air, water, dirt, can improve the working life of pneumatic element and the precision of adjustable pressure.Common filtering pressure reducing valve in the market, its structure generally includes valve body, the valve gap being connected with valve body upper end, the water cup being connected with valve body lower end, and be located at the diaphragm between valve body and valve gap, between described valve body and diaphragm, coordinate and form upper chamber, between valve body and water cup, coordinate and form lower chambers, on described valve body, be respectively equipped with the suction port being communicated with lower chambers, the air outlet being communicated with upper chamber, and the pore that is communicated with described upper chamber and lower chambers, described valve gap is provided with adjusting handle, described adjusting handle is provided with adjusting screw rod, in described valve gap, be provided with and the corresponding regulating nut of adjusting screw rod, between described regulating nut and diaphragm, be provided with definite value spring, in valve body, be provided with the spool being equipped with pore, on described spool, moulding is provided with valve rod, the top of described valve rod is passed described pore and is offseted and coordinate with diaphragm, between described spool and valve body, be provided with balance spring, in described water cup, be fixed at filtering mechanism, described filtering mechanism comprises cyclone blade, element kit, and drain valve, described cyclone blade is fixedly connected with valve body lower end, element kit comprises the filter core being sheathed in cyclone blade, and the manger board of filter core bottom is located in installation, described manger board is provided with set screw, the top of described set screw is passed filter core and is fixedly connected with valve body, described drain valve is installed the bottom of being located at water cup.Its working principle is: during work, pressurized gas enters in water cup from suction port, under the effect of cyclone blade, gas constantly rotates, liquid water in gas and solid particulate matter are along with rotary centrifugal force effect separated deposition gradually, gas after separation flow through successively filter core, pore, upper chamber, and finally from air outlet, discharge; When turn adjusting handle, by regulating nut, compress definite value spring, after definite value spring stress, compress diaphragm, there is deformation the valve rod of conflicting in diaphragm, valve rod band movable valve plug is moved down under the effect of definite value spring, makes to form path between upper chamber, pore and lower chambers, by the gap length between regulating spool and pore, change gas flow through the flow velocity of pore, and then change the pressure size of gas output, reach the effect of air pressure adjustment.
Yet, above-mentioned filtering pressure reducing valve is unreasonable because structure arranges, cause existing following defect: first, due to the setting that is formed in one of spool and valve rod, during work, spool is synchronized with the movement with valve rod, and valve rod is that axial motion occurs under the conflict of diaphragm, for guaranteeing the coaxality of stem movement, therefore distance is less between general valve rod and pore inwall, when valve rod is frequently subject to diaphragm and compresses, make valve rod easily with between pore inwall produce and rub, cause existing between valve rod and valve body certain drag effect, thereby affect the sensitivity of air pressure adjustment; The second, because the common volume setting of valve body is less, the pore adapting with valve rod is set in valve body, difficulty of processing is larger, causes manufacture cost higher; The 3rd, owing to arranging by filter core, manger board and set screw, coordinate the element kit forming, during installation, filter core need to could be located in cyclone blade by fixed cover by manger board and set screw mating reaction, cause installing comparatively inconvenience, the efficiency of loading and unloading is lower, and a plurality of component have also increased extra manufacture cost; The 4th, because drain valve structure setting is comparatively complicated, versatility is poor, cause using having inconvenience, and cost is higher.
