Abstract
A hydraulic-control valve including check valve, gate valve, blowoff valve and cock valve features its control system, which is composed of electric motor, oil cylinder, electromagnetic valve, overflow valve and pressure relay and can be used to control 1-10 valves. For the check valve, gate valve and blowoff valve, its existing design is not changed but its drive mode is such changed so that an oil cylinder is additionally used and the handwheel is omitted. For the cock valve, a rotary oil cylinder is added to it. Its advantages include saving labour, high safety and reliability and centralized, programmed automatic control.
Description
Fluid-control valve: belong to valve type, the valve of the every handwheel transmission of fluid-control valve removes handwheel drive assembly dress hydraulic control hydraulic cylinder assembly, all belongs to fluid-control valve.
Fig. 1 is the stop valve of handwheel transmission, and its structure is made up of handwheel, follower, valve rod, filler, valve body, flap, and the former design of valve is constant, change the kind of drive, remove handwheel assembly 1, load onto hydraulic cylinder assembly 9 referring to Fig. 5, the 2nd, the stop valve valve body assembly promptly is a fluid-control valve.
Fig. 2 is the gate valve of handwheel transmission, and its structure is made up of handwheel, follower, valve rod, filler, valve body, flashboard, and the former design of valve is constant, change the kind of drive, remove handwheel assembly 3, load onto hydraulic cylinder assembly 9 referring to Fig. 6, the 4th, the gate valve body assembly promptly is a fluid-control valve.
Fig. 3 is oblique ball formula blowdown valve, and its structure is made up of handwheel, follower, valve rod, filler, valve body, oblique globe disk, and the former design of valve is constant, change the kind of drive, remove handwheel assembly 5, load onto hydraulic cylinder assembly 9 referring to Fig. 7, the 6th, the blowdown valve body assembly promptly is a fluid-control valve.
Fig. 4 is a plug valve, and its structure is made up of follower, filler, flap, valve body, the 7th, and follower, the 8th, the stopcock valve body, the former design of valve is constant, increases by a rotating hydraulic cylinder in the upper end, and is middle to stretching out a cuboid axle.Referring to Fig. 9, the former design of valve is constant, increases rotating hydraulic cylinder, promptly is the cock-type fluid-control valve.
Fig. 8 is the higher valve mechanism of work temperature of valve.Oil cylinder and valve disconnect, and valve rod and piston rod disconnect, and with pillar, support arm transmission, can not import very high temperature into to oil cylinder like this.The 10th, pillar, the 11,13, the 14th, bearing pin, the 12nd, support arm.
The control system of fluid-control valve is a hydraulically controlled station.Figure 12 is the hydraulically controlled station structure, and it is made up of motor, pressure gauge, relief valve, solenoid valve, casing, oil pump, pressure relay, fuel tank etc.The hydraulically controlled station control valve is counted 1-10 valve, and may command is 10 at most.
The main feature of fluid-control valve:
