Abstract
The utility model relates to a filtering pressure regulating valve, which comprises a pressure regulating screw stem, a valve cap, a pressure regulating spring, a superior pressure regulating spring seat, a pressure regulating gearing device, a valve body, a filtering net, a pressure regulating spring, a backspring seat and a valve core; wherein, the pressure regulating spring, the pressure regulating gearing device and the backspring are connected in turn and arranged between the superior pressure regulating spring seat and the backspring seat; the superior pressure regulating spring seat, the pressure regulating gearing device, the pressure regulating spring and the backspring are positioned inside the cavity formed by the valve body and the valve cap; the pressure regulating screw stem and the valve cap form a screw pair, and the inferior end of the pressure regulating screw stem is connected with the superior pressure regulating spring seat; on the valve body an air inlet and an air outlet are provided; the pressure regulating gearing device consists of a piston valve, a valve stem and an O-shape ring. Due to changing components such as the membrane inside the pressure regulating gearing device into the piston valve, the utility model solves the technological problem of unideal pressure regulating performance of the filtering pressure regulating valve caused by easy membrane distortion and the need of tight matching with the pressure regulating gearing element.
Description
Technical field
The utility model relates to the filtration pressure regulator valve.
Background technique
Existing filtration pressure regulator valve comprises screw press, valve gap, pressure adjusting spring, last pressure adjusting spring seat, the pressure regulation driving mechanism, valve body, filter screen, Returnning spring, return spring holder and spool, pressure adjusting spring, pressure regulation driving mechanism and Returnning spring are linked in sequence and are arranged between pressure adjusting spring seat and the return spring holder, last pressure adjusting spring seat, the pressure regulation driving mechanism, pressure adjusting spring and Returnning spring are positioned at the cavity of valve body and valve gap formation, screw press and valve gap form screw pair and its underpart connects the pressure adjusting spring seat, offer suction port on the valve body, the air outlet, larynx hole and via hole, the shape and size of filter screen and valve body air intake passage are complementary, be installed on the air intake passage of valve body, the pressure regulation driving mechanism mainly is made up of diaphragm and pressure regulation Force transmission parts, because the diaphragm easy deformation and with problems such as the pressure regulation Force transmission parts need closely cooperate, make its pressure regulating performance good inadequately.
The model utility content
