けて成る圧力調整弁。A lid body 29 having a first port 10 for taking in compressed air is fixed to the lower end of the valve housing 12 which has a cylinder part 30 and has a second port 11 for delivering compressed air on the side surface. Annular backings 34 and 35 are attached to the upper and lower surfaces of the valve body 31, which is slidably fitted inside the valve body 31 and is pressed against the upper surface of the lid body 29 by the compression spring 20.
5 has a sufficiently smaller diameter than the valve body 31, and an O-ring 33 is provided on the sliding surface between the cylinder portion 30 and the valve body 31, below the second port 11, so that the valve body 31 At the bottom, there is a ventilation passage 37 consisting of a horizontal passage 37a that opens on the side surface above the O-ring 33, and a vertical passage 37b that intersects with this horizontal passage 37a and opens at the center of the lower surface of the valve body 31.
The upper guide column 39 of the auxiliary valve 38 is slidably inserted into the vertical passage 37b, and a ventilation passage 49 is formed between the upper guide column 39 and the vertical passage 37b. Furthermore, sub valve 3
An annular backing 40 whose lower surface is supported by a flange 43 is provided at a position below the upper guide column 39 of 8, and a lower guide column 4 below the flange 43 is provided.
1 is slidably inserted into the small diameter portion 42a of the circular hole 42 of the lid body 29, and the upper surface of the step portion 42C and the lower surface of the flange portion 43 connect the small diameter portion 42a and the upper large diameter portion 42b. A compression spring is provided between the lower guide column portion 41 and both ends thereof are connected to the lower surface of the lower guide column portion 41 and the large diameter portion 42b.
A ventilation passage 45 is provided that opens to the side surface located inside, and the flange portion 4 of the sub-valve 3B is provided on the upper inner circumferential surface of the large diameter portion 42b.
A stop ring 46 that comes into contact with the auxiliary valve 38 to restrict the amount of rise of the sub-valve 38 is fixed, and the distance 1 between the lower surface of the stop ring 46 and the upper surface of the flange portion 43 when the valve body 31 is at its lowest position is Backing 34 on the top surface of the valve body in the state
The distance between the upper surface of the backing 34 and the lower surface of the stepped portion 47 on the inner surface of the upper part of the valve housing is smaller than the distance between the upper surface and the lower surface of the stepped portion 47 on the inner surface of the upper part of the valve housing. A compression spring 20 is formed with a concave groove 48 communicating with the second port 11, is screwed into the upper part of the valve housing 12, and presses the valve body 31 described above.
A pressure regulating valve is provided with a restricting passage 2B on an regulating screw 19 supported at the upper end of the pressure regulating valve.
