Abstract

DC60 in pilot valve The valve box that surrounds the main valve has no flange. And the valve box has been Held in a state that has been spliced between pipe flanges In a pilot valve that uses a pilot valve to control the thrust to be used to control the main valve 2, the main valve 2 is open and closed.The valve box 6, which surrounds the main valve 2, is sandwiched between the resulting pipe flanges F, F1. It has been tightened together with bolts B, B1, ... and N, N1, ... nuts. In addition to this, valve boxes 6 are also flanged at the connecting ends 11, 12 for It is connected to pipe flanges F, F1 and has inlet 7 and outlet 8 for the compressed fluid, respectively, the cover flange neck 18 that extends upward from valve box 6 is limited to the upper position. Side wall corresponding to bolts B, B1, protruding between F, F1 pipe flanges and adjacent on the line. Around the circumference of the pipe flanges F, F1 so that the collar flange 18 can pass through the interval between the bolts B, B1 at this limit in the pilot valve. The valve enclosing the valve that surrounds the main valve does not have a flange. And the valve box has been Held in a state that has been spliced between pipe flanges In a pilot valve that uses a pilot valve to control the force required to control the main valve 2, the main valve 2 is opened and closed.The valve box 6, which surrounds the main valve 2, is sandwiched between the resulting pipe flanges F, F1. Get tightened together with bolts. B, B1 ... and nuts N, N1 ... In addition to this, valve box 6 is also flanged at connection end, 11,12 for connection to pipe flanges F, F1 and has Inlet 7 and outlet 8 for the compressed fluid, respectively, the cover flange neck 18 projecting upward from the valve box 6 is limited to where the upper Side wall corresponding to bolts B, B1 extending between F, F1 pipe flanges and adjacent on the line. Around the circumference of pipe flanges F, F1 so that the collar flange 18 can pass through the interval between bolts B, B1 at this limit.

Claims (2)

1.Wafer-operated valves that use a pilot valve to control the thrust required for Activate the main valve to open and close the main valve. Included The valve box that surrounds the main valve. The valve box is sandwiched between the flanges that have been tightened. Together with bolts and nuts The valve box does not have a flange on the connection end for Connection to such pipe flanges and have inlet and outlet for the compressed fluid respectively. And the collar flange protruding upward from the said valve box Such cover flange neck included. To the gap so that the compressed fluid can pass through The flanged neck, which contains only the valve stem, passes through it.The stem links the main valve with the drive for controlling its opening. According to the variation in pressure fed from the pilot valve, the flange neck is limited only to the side wall position corresponding to the bolts located. Stick together in a smaller width, the gap between such bolts that will differ depending on the type. Of such pipe flanges that have been selected according to the size of such valves to cover the flange necks It can pass through a channel between the bolts protruding between the flanges of such pipe. And adjacent on the circumference of such pipe flanges 2. Wafer-style guide valve according to claim 1, which has a matching surface for each section. Connecting ends that are to be matched with such pipe flanges can also be recessed. In the ring-shaped groove And seal assemblies can be assembled in such annular grooves.
