Description
Technical field
The utility model relates to a kind of hydraulic executer of opening or closing inside screw non-rising stem type gate valve in the seagoing vessel ballast tank.
Background technique
Along with the development of science and technology with to the requirement of automatic control, and large-scale seagoing vessel ballast tank often will pour into the characteristics of seawater, the stop valve of ballast tank inboard or gate valve, usually realize that by hydraulic remotely-controlled the opening and closing of valve are (because ballast tank is in the situation that seawater immersion, the crewman can't enter in the cabin, and the moving local operation of armrest can't be realized opening or throttle down).
In order to realize hydraulicefficiency telecontrol, present technology is at the valve rod of stop valve or gate valve straight journey piston-type hydro compressing cylinder to be installed, by the control hydraulic jack move up and down move up and down with the valve plate of movable valve, thereby realize the opening and closing of valve.
But this control mode exists a great defective: hydraulic jack is when closing (or unlatching) valve, and hydraulic jack has been full of the high pressure liquid force feed in a side of piston, can satisfy the Driving force when closing (or unlatching) valve the short time.Because the tiny leakage characteristics of hydraulic jack and hydraulic control component, prolongation along with the time behind the valve closing (or unlatching), hydraulic jack can progressively descend at the oil pressure of the instinct high pressure liquid force feed of piston one side, thereby the thrust that hydraulic jack acts on the valve plate descends thereupon, after thrust dropped to a critical value, the valve plate of valve will be pushed open by ducted pressure medium.This reason just, present technology is in the hydraulicefficiency telecontrol system pressure supplementing function to be arranged, could satisfy long-term the closing of valve (or opening) requirement, and ftercompction often is cumbersome, and if under the state of emergency, hydraulic system is out of order or power supply loses, this pressure supplementing function will be lost, and has great potential safety hazard.
The model utility content
For the problems referred to above that the inside screw non-rising stem type gate valve that solves existing seagoing vessel ballast tank inboard exists with hydraulic executer, the utility model provides a kind of and need not ftercompction, uses the many revolution hydraulic executers of the interior inside screw non-rising stem type gate valve of ballast tank of safety.
The utility model adopts following technological scheme:
The many revolution hydraulic executers of inside screw non-rising stem type gate valve in the ballast tank, the drive bevel gear that comprises fluid motor, driven by fluid motor, with the driven wheel of differential of drive bevel gear engagement, with the rotating nut of driven wheel of differential synchronous rotary, described many revolution hydraulic executers also comprise the bounding means that limits described rotating nut lifting, and described rotating nut rotates synchronously with the valve rod that the interior inside screw non-rising stem type gate valve of driving ballast tank opens and closes.
As preferred a kind of scheme: described drive bevel gear, driven wheel of differential, rotating nut are contained in the seal casinghousing, and described valve rod stretches out described seal casinghousing, are provided with seal ring between valve rod and the seal casinghousing.
Described seal casinghousing comprises recline fixing cog casing and lower gear casing, the described casing that cogs connects fluid motor by connection bracket, the described casing top that cogs is provided with capping, described lower gear casing connects a sealing cover by sealed support, described valve rod stretches out described sealing cover, is provided with described seal ring between valve rod and the sealing cover.
The output shaft of described fluid motor connects the motor drive shaft that surges, and described fluid motor transmission shaft is by coupling connection teeth wheel shaft, and described gearing shaft is fixedly connected with drive bevel gear; Described fluid motor transmission shaft, coupling, gearing shaft are positioned at described seal casinghousing.
As preferred another kind of scheme: described drive bevel gear, driven wheel of differential, rotating nut are contained in the non-pressurized body.
Described non-pressurized body comprises recline fixing cog casing and lower gear casing, the described casing that cogs connects fluid motor by connection bracket, the described casing top that cogs is provided with capping, the affixed sealed support in described lower gear casing lower end, described valve rod stretches out described sealed support, blow-by between valve rod and the sealed support.
The output shaft of described fluid motor connects the motor drive shaft that surges, and described fluid motor transmission shaft is by coupling connection teeth wheel shaft, and described gearing shaft is fixedly connected with drive bevel gear; Described fluid motor transmission shaft, coupling, gearing shaft are positioned at described non-pressurized body.
Further, described sealed support upper end is fixedly connected with support block, and described rotating nut is installed on this support block by bearing, and described casing and the support block of cogging consists of described bounding means.Like this, rotating nut is installed in and cogs between casing and the support block, can only rotate, and can't move up and down.
Preferably, described gearing shaft is connected with the casing that cogs by bearing, and described driven wheel of differential is connected with the casing that cogs by bearing.
Preferably, described rotating nut is fixedly connected with valve rod.
Technical conceive of the present utility model is: to fluid motor input high pressure liquid force feed, drive the rotation of fluid motor transmission shaft, by coupling driven gear transmission shaft and drive bevel gear rotation, drive bevel gear drives the driven wheel of differential rotation, the rotation of driven wheel of differential driven rotary nut, bounding means so that rotating nut can only rotate, can't move up and down, rotating nut is with the ovable valve stem synchronous rotary again, because inside screw non-rising stem type gate valve only needs rotary valve rod, need not valve rod and just move up and down and to open valve, so realized the opening and closing of inside screw non-rising stem type gate valve by rotatablely moving with the valve rod of rotating nut synchronous rotary.
In the inside screw non-rising stem type gate valve, described valve rod lower end is threaded with valve plate, because valve rod is followed rotating nut and rotated synchronously, can not rotate and valve plate is limited, so valve rod drives the valve plate elevating movement, thereby opens or closes inside screw non-rising stem type gate valve.Because valve rod is threaded with valve plate, and screw thread has self-locking performance, do not have under the hydraulic pressure oil condition also can self-locking, so need not ftercompction, has solved needing ftercompction, using unsafe problem of present hydraulicefficiency telecontrol technical field existence.
The beneficial effects of the utility model are: the many revolution hydraulic executers of the interior inside screw non-rising stem type gate valve of ballast tank that provide a kind of and need not ftercompction, use safety.
