Abstract
The utility model discloses a valve plate opening device for a hydraulic control valve. The valve plate opening device comprises a shoe plate fixedly installed on the inner wall of a valve cover seat, a linear bearing installed on the upper end of the shoe plate, a pull bar installed in the linear bearing, a tooth bar on the outer wall of the pull bar, a rotating shaft penetrating through the valve cover seat, and a gear engaged with the tooth bar and arranged at the front end of the rotating shaft which is rotatably installed in the valve cover seat. The valve plate opening device is reasonable in structural design. The valve plate is opened by employing a rack-and-pinion transmission mode, which substantially reduces weight. The sealing performance of a valve port is improved.
Description
Technical field
The utility model relates to hydraulic control valve, specifically belongs to the valve plate opening device of hydraulic control valve.
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 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 bigger just remarkable more.
The model utility content
The purpose of the utility model provides a kind of valve plate opening device of hydraulic control valve, and reasonable in design adopts the gear rack kind of drive to open valve plate, and weight obviously alleviates, and the sealability of valve port further improves.
The technological scheme of the utility model is following:
The valve plate opening device of hydraulic control valve; Include the dunnage that is fixedly installed on the valve gap seat inwall, the dunnage upper end is equipped with linear bearing, in the said linear bearing pull bar is installed; The outer wall of pull bar is provided with tooth bar; Crossed rotating shaft in the valve gap seat, the front end of rotating shaft is equipped with the gear that is meshed with tooth bar, and rotating shaft is rotated and is installed in the valve gap seat.
Be fixed with bearing support on the said valve gap seat outer wall, bearing support is passed in rotating shaft.
The utility model adopts the gear rack kind of drive to open valve plate, the rising or the decline of control valve plate, and opening force is bigger, and stable, reasonable in design, opening and closing are convenient and swift, and weight obviously alleviates, and 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 valve plate opening device of hydraulic control valve includes the dunnage 2 that is fixedly installed on valve gap seat 1 inwall; Dunnage 2 upper ends are equipped with linear bearing 3, and pull bar 4 is installed in the linear bearing 3, and the outer wall of pull bar 4 is provided with tooth bar 5; Crossed rotating shaft 6 in the valve gap seat, the front end of rotating shaft 6 is equipped with the gear 7 that is meshed with tooth bar, and rotating shaft is rotated and is installed in the valve gap seat; Be fixed with bearing support on the valve gap seat outer wall, bearing support 8 is passed in rotating shaft.
