Filtering pressure reducing valve sets up filter element on the basis of reduction valve, ensure that output pressure also carries out filtration treatment to source of the gas while stable, such as remove the impurity such as oil, water, dirt in pressurized air, the working life of pneumatic element and the precision of adjustable pressure can be improved.Existing filtering pressure reducing valve generally heads on by spool the pressure that piston movement controls air outlet, spool be out of order can not in time close port time, the air pressure of air outlet can be increasing and can not discharge in time, and larger fault occurs even have an accident, and has certain potential safety hazard.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides the filtering pressure reducing valve that a kind of Security is high.
For achieving the above object, the utility model adopts a kind of filtering pressure reducing valve, comprise valve body, be arranged on the water tumbler under valve body, be arranged on the valve gap of valve body upper end, be arranged on the pressure-regulating device of valve gap upper end, be arranged on the element kit in water tumbler and the piston be arranged in valve body and spool, suction port and air outlet is formed in valve body, piston and form piston cavity between suction port and the upper wall of air outlet, feedback pore is formed between air outlet and piston cavity, suction port and air outlet are connected with the inner chamber of water tumbler respectively, valve body is axially provided with valve port between air outlet and water tumbler, spool gets lodged in valve port lower end, spool upper end forms valve rod and withstands on piston centre through valve port, element kit comprises filter core, filter cartridge seat, cyclone blade and manger board, filter cartridge seat is connected on the valve body of spool lower end, balance spring is provided with between filter cartridge seat and spool, cyclone blade is connected in filter cartridge seat, filter core is enclosed in outside filter cartridge seat, water tumbler is divided into filter core and is connected the air outlet space be connected with air outlet in admission space and filter core with suction port outward by filter core and filter cartridge seat, manger board is arranged on filter cartridge seat lower end, the corresponding valve rod of piston centre forms pore, conical entrance is formed below pore, seal ring is provided with in conical entrance, closed spool chamber is formed between spool lower end and filter cartridge seat, valve rod center lower end axially forms the valve rod hole connecting spool chamber, valve rod exhaust port is formed between valve rod hole and valve rod side.
The utility model is set to described pressure-regulating device further and comprises handwheel, screw press, look nut, pressure adjusting spring, screw press is fixedly connected with handwheel, look nut is flexibly connected by screw thread with screw press, and pressure adjusting spring is connected between look nut lower end and piston upper end.
The conical entrance place that the utility model is set to the corresponding pore of described valve stem tip is further provided with O type circle.
Air of the present utility model comes in enter water tumbler by rotation blade from suction port, fall after impurity to enter in filter core through the filter element filtering in water tumbler, spool is opened from valve port by rotation hand wheel, air after filtration enters air outlet through valve port, the air of air outlet enters in piston cavity and spool chamber respectively by feedback pore and valve rod hole, the air pressure of air outlet is fed back to piston and spool, controls the motion of spool.
The beneficial effects of the utility model offer a pore at the piston centre of filtering pressure reducing valve, pore is blocked at ordinary times by spool upper end, spool break down can not in time on move time, the air pressure of air outlet can back down piston, pore is opened, and the gas of air outlet is discharged by pore, thus discharges potential safety hazard, ensure the normal operation of filtering pressure reducing valve, improve Security.When spool moves fortune downwards, directly discharge from valve rod hole by the gas of spool extruding in spool chamber, improve the stability of spool.
