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

A kind of filtration pressure regulator valve
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
The utility model provides a kind of filtration pressure regulator valve, to solve the existing imperfect technical problem of pressure regulator valve pressure regulating performance of filtering.
In order to solve above technical problem, the technological scheme that the utility model is taked is:
A kind of filtration pressure regulator valve, comprise 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, it is characterized in that, described pressure regulation driving mechanism comprises that piston cuts down, valve rod and O type ring, the piston with in the pressure regulation driving mechanism of described pressure adjusting spring cuts down and joins, valve rod one end cuts down with piston and is connected, and the other end is connected with return spring holder with direct and valve body formation sliding pair and sealing pair by O type ring and Returnning spring.
After having adopted technique scheme, because the diaphragm in the pressure regulation driving mechanism etc. is improved to piston valve, has solved because of the diaphragm easy deformation with problems such as the pressure regulation Force transmission parts need closely cooperate and caused filtering the imperfect technical problem of pressure regulator valve pressure regulating performance.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Embodiment
As shown in Figure 1, a kind of filtration pressure regulator valve, comprise screw press 1, valve gap 2, pressure adjusting spring 3, last pressure adjusting spring seat 4, the pressure regulation driving mechanism, valve body 5, filter screen 6, Returnning spring 7, return spring holder 8 and spool, pressure adjusting spring 3, pressure regulation driving mechanism and Returnning spring 8 are linked in sequence and are arranged between pressure adjusting spring seat 4 and the return spring holder 8, last pressure adjusting spring seat 4, the pressure regulation driving mechanism, pressure adjusting spring 3 and Returnning spring 7 are positioned at the cavity of valve body 5 and valve gap 2 formation, screw press 1 forms screw pair with valve gap 2 and its underpart connects pressure adjusting spring seat 4, offer suction port 51 on the valve body 5, air outlet 52, larynx hole and via hole, filter screen 6 is complementary with the shape and size of valve body suction port 51 passages, be installed on suction port 51 passages of valve body, the pressure regulation driving mechanism comprises that piston cuts down 9, valve rod 10 and O type ring 11, piston in pressure regulation bullet 3 and the pressure regulation driving mechanism cuts down 9 and joins, valve rod 10 1 ends cut down 9 with piston and are connected, and the other end is connected with return spring holder 8 to form sliding pair and sealing pair with valve body by O type ring 11 and Returnning spring 7.During use, screw press 1 turns clockwise, and makes pressure adjusting spring 3 down moving piston valve 9 of pressure zone and valve rod 10, this moment valve rod 10 with the downward cracking pressure of valve port, outlet pressure rises thereupon; Otherwise screw press 1 is rotated counterclockwise, and makes pressure adjusting spring 3 up go up drive piston valve 9 toward rising, and 9 generations of this moment valve rod 10 and piston valve, one exhaust clearance downgrades pressure with the outlet pressure minimizing.
