Abstract
The utility model discloses a piston type water pressure control valve which comprises a valve body. A valve cover is installed on a valve cover seat at the upper end of the valve body. Two parallel support seats are arranged on the inner wall of the valve body. The end surfaces of the two support seats are in a half-circle shape. The two support seats are mutually matched and are clamped with a valve plate. The upper end of the valve plate is fixedly connected with a valve rod. A partition board is arranged on the inner wall of the valve cover seat. The valve rod penetrates through the partition board. An adjusting spring is arranged on the valve rod and between the partition board and the valve plate. A pressure meter is arranged on the side wall of the valve body. The piston type water pressure control valve is reasonable in structural design and convenient and fast to open and close. The weight of the piston type water pressure control valve is obviously reduced, and a sealing property of a valve port is further improved.
Description
Technical field
The utility model relates to hydraulic control valve, specifically belongs to a kind of piston-type underwater pressure control valve.
Background technique
Hydraulic control valve is take pipe medium pressure as power, the valve that opens and closes, regulates.It by a main valve and conduit, needle-valve, ball valve and the pressure gauge etc. set up form, according to the difference in the purpose of using, function place, can develop into remote control float valve, reduction valve, buffer valve, flow dontroller, Decompression valves, hydro electric brake control valve, emergency shut-in valve etc.Pilot valve moves with the liquid level of medium and the variation of pressure, because the pilot valve kind is a lot, can use separately or several being used in combination, and just can make main valve obtain the function that water level and hydraulic pressure and flow etc. are carried out independent and compound adjusting.But the similar stop valve of valve body of main valve, during valve wide open, its pressure loss is more much bigger than other valves, and each aperture loss coefficient is approaching with full-shut position, increases severely, and valve aperture is larger just more remarkable.
The model utility content
The purpose of this utility model is to provide a kind of piston-type underwater pressure control valve, reasonable in design, and opening and closing are convenient and swift, fast detecting hydraulic pressure, weight obviously alleviates, and the sealability of valve port further improves.
The technical solution of the utility model is as follows:
A kind of piston-type underwater pressure control valve, include valve body, it is characterized in that: on the valve gap seat of described valve body upper end, valve gap is installed, valve interior wall is provided with two supporting bases that are parallel to each other, the end face semicircular in shape of described supporting base, two supporting bases cooperatively interact and fasten with valve plate, the upper end of valve plate is fixedly connected with valve rod, described valve gap seat inwall is provided with dividing plate, described valve rod passes dividing plate, valve rod between described dividing plate and valve plate is provided with Regulation spring, and the sidewall of described valve body is provided with pressure gauge.
The end face of described supporting base is provided with the step-like draw-in groove that is complementary with valve plate, is provided with seal ring in draw-in groove.
The utility model adopts piston cylinder operator, controls rising or the decline of valve plate, and opening force is larger, and stable, and reasonable in design owing to having increased spring, makes opening and closing convenient and swift, and weight obviously alleviates, and the sealability of valve port further improves.
Description of drawings
Fig. 1 is structural representation of the present utility model.
