Abstract
The utility model relates to a kind of valve, especially a kind of hydraulic program control valve.Flap is fixed on one end of valve rod, flap is arranged in valve body, valve gap is fixedly connected with valve body, a packing cavity is provided with in valve gap, filler is placed in packing cavity, pressing plate involution is on packing cavity, filler is encapsulated in wherein, drive assembly to comprise oil hydraulic cylinder, piston, piston is arranged in cylinder body, and piston is fixedly connected with valve rod, valve gap is positioned at above packing cavity and is provided with a scaffold, scaffold and valve gap are wholely set, and oil hydraulic cylinder is fixedly connected with scaffold, and oil hydraulic cylinder is provided with two dedicated liquid passages.Said structure arranges dedicated liquid passage on oil hydraulic cylinder, so the flow velocity of liquid is faster, accelerate the keying speed of valve, because relief value ratio is very fast, therefore it also avoid pressured fluid and enter valve body by gap, and mix with valve body media, establish piston guide band in the side of piston, piston can be made quick smoothly more movable in cylinder body.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of hydraulic program control valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
And wherein hydraulic program control valve is exactly the one of valve, sequencing valve passes through program control, electric actuator is used to carry out control valve switch, generally assigning instruction by telecommunication to actuator realizes telecontrol valve switch, hydraulic program control valve is the valve driven with liquid compression, but owing to there is no special flow channel for liquids, open and close speed slow, and liquid easily mixes with the medium in valve body.
Summary of the invention
The purpose of this utility model is, provides one to prevent pressured fluid from mixing with valve body media, opens and closes fireballing hydraulic program control valve.
The utility model solves the technological scheme that its technical problem adopts: a kind of hydraulic program control valve, comprise valve body, valve gap, flap, valve rod, flap is fixed on one end of valve rod, flap is arranged in valve body, valve gap is fixedly connected with valve body, also comprise driving assembly, a packing cavity is provided with in valve gap, filler is placed in packing cavity, pressing plate involution is on packing cavity, filler is encapsulated in wherein, assembly is driven to comprise oil hydraulic cylinder, piston, piston is arranged in cylinder body, piston is fixedly connected with valve rod, valve gap is positioned at above packing cavity and is provided with a scaffold, scaffold and valve gap are wholely set, oil hydraulic cylinder is fixedly connected with scaffold, oil hydraulic cylinder is provided with two dedicated liquid passages.
Of the present utility modelly to be set to further: oil hydraulic cylinder comprises cylinder body, protecgulum, bonnet, and the both sides that protecgulum and bonnet are encapsulated in cylinder body form oil hydraulic cylinder, protecgulum and bonnet is respectively equipped with a L-type fluid passage, as dedicated liquid passage.
Of the present utility modelly to be set to further: also comprise piston guide band, piston guide band is fixedly installed on the side of piston.
Said structure arranges dedicated liquid passage on oil hydraulic cylinder, so the flow velocity of liquid is faster, accelerate the keying speed of valve, because relief value ratio is very fast, therefore it also avoid pressured fluid and enter valve body by gap, and mix with valve body media, and the fluid passage of L-type, be conducive to pressure release when piston presses down, establish piston guide band in the side of piston, piston can be made quick smoothly more movable in cylinder body.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
