Abstract

The utility model discloses a hydraulic control valve capable of preventing reverse flow, comprising a valve body, wherein a valve cover base at the upper end of the valve body is provided with a valve cover, the inner wall of the valve body is provided with two support bases which are mutually parallel, the end face of each support base is semicircular, the two support bases are mutually matched and are blocked and combined with a valve plate, the upper end of the valve plate is fixedly connected with a valve rod, a piston which is matched with the valve cover base in a sliding manner is arranged above the valve plate, the piston is arranged at the top of the valve rod in a pressing manner, an adjusting screw rod is arranged above the piston in the pressing manner, an elastic slice pushes against the lower part of the valve plate, the elastic slice is in a bending shape, the end part of the elastic slice is fixed on the support bases, each support base is provided with a step-shaped limber hole, the inner wall of the limber hole is provided with a conical hole, the conical hole is internally provided with a ball sealer, and a spring is arranged outside the ball sealer in the pressing manner. The hydraulic control valve disclosed by the utility model has a reasonable structural design and is convenient and rapid to open and close, an acting force is small when the valve plate is opened by virtue of an elastic force of a spring piece, when inlet pressure is higher than a set value, an air vent hole is conducted, inlet water pressure is reduced, and sealing property of a valve port is further improved.

Description

The hydraulic control valve of anti-back flow
Technical field
The utility model relates to hydraulic control valve, specifically belongs to the hydraulic control valve of anti-back flow.
Background technique
Hydraulic control valve is to be power with the pipe medium pressure, the valve that opens and closes, regulates.It by a main valve form with the conduit of setting up, needle-valve, ball valve and pressure gauge etc., different according to 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 combinations is used, the function that just can make the main valve acquisition that water level and hydraulic pressure and flow etc. are carried out independent and compound adjusting.But present hydraulic control valve opening force is bigger, and opening speed is slow, influences its usability.
The model utility content
The purpose of the utility model provides a kind of hydraulic control valve of anti-back flow; Reasonable in design, opening and closing are convenient and swift, and the elastic force through spring sheet makes that active force was less when valve plate was opened; When inlet pressure surpasses setting value; The vent conducting alleviates import hydraulic pressure, and the sealability of valve port further improves.
The technological scheme of the utility model is following:
The hydraulic control valve of anti-back flow includes valve body, on the valve gap seat of said valve body upper end valve gap is installed; The valve interior wall upper and lower end is respectively equipped with two each other corresponding supporting bases, the end face semicircular in shape of described supporting base, and two supporting bases cooperatively interact and valve plate fastens; The upper end of valve plate is fixedly connected with valve rod, and the top of valve plate is provided with the piston that is slidingly matched with the valve gap seat, and piston is pressed on the top of valve rod; The top of piston is pressed and is equipped with adjusting screw rod, and described valve plate below overhead has bouncing plate, and described bouncing plate is bending shape; The end of bouncing plate is fixed on the supporting base; The outlet end of valve body is fixed with the anti-back flow plate, has a plurality of water passage holes on the anti-back flow plate, and the outside of water passage hole is hinged with the water blockoff plug.
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 the draw-in groove.
The utility model adopts piston cylinder operator, reasonable in design, and opening and closing are convenient and swift; Elastic force through spring sheet makes that active force was less when valve plate was opened, when inlet pressure surpasses setting value, vent conducting; Alleviate import hydraulic pressure, the sealability of valve port further improves.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, the hydraulic control valve of anti-back flow includes valve body 1; On the valve gap seat 3 of valve body 1 upper end valve gap 2 is installed, the valve interior wall upper and lower end is respectively equipped with two corresponding each other supporting bases 4,5, the end face semicircular in shape of supporting base; Two supporting bases cooperatively interact and valve plate 6 fastens, and the upper end of valve plate is fixedly connected with valve rod 7, and the top of valve plate is provided with the piston 8 that is slidingly matched with the valve gap seat; Piston 8 is pressed on the top of valve rod 7, and the top of piston is pressed and is equipped with adjusting screw rod 9, and valve plate 6 below overheads have bouncing plate 12; Bouncing plate 12 is bending shape, and the end of bouncing plate is fixed on the supporting base 4; The end face of supporting base is provided with the step-like draw-in groove 10 that is complementary with valve plate, is provided with seal ring 11 in the draw-in groove 10, and the outlet end of valve body 1 is fixed with anti-back flow plate 12, has a plurality of water passage holes 13 on the anti-back flow plate 12, and the outside of water passage hole 13 is hinged with water blockoff plug 14.
