Description
Technical field
The present invention relates to a kind of stop valve, specifically, the present invention relates to a kind of pneumatic quick closing valve stop valve.
Background technique
Hand stop valve is generally to realize moving up and down of valve rod by the screw thread on valve rod, thereby realizes closing and opening of valve, very slow when the stop valve of this structure is closed.For realizing the quick closedown of stop valve, on market, there is adopting the quick closing valve stop valve of air cylinder driven, the pneumatic quick closing valve stop valve of prior art is, in valve gap side, cylinder assembly is set, and between valve gap and valve disc, increases Compress Spring.If need stop valve in opening state, in cylinder assembly, piston rod stretches out, and blocks the stop nut on valve rod, and valve rod cannot be downward like this, and stop valve is just in opening state; As need quick closedown, and only need cylinder assembly that piston rod is return, under Compress Spring effect, valve rod moves down rapidly, and the rapid note of valve disc and valve seat closes, and stop valve is just in closed condition.This pneumatic quick closing valve stop valve has simple in structure, closes feature rapidly.If but cylinder medium power medium occurs that piston rod cannot normally stretch, and also just cannot realize the quick closedown of stop valve extremely.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of simple in structurely, can solve existing pneumatic quick closing valve stop valve and occur extremely affecting the pneumatic quick closing valve stop valve of stop valve quick closedown problem because of cylinder medium power medium.
The present invention is achieved through the following technical solutions technical goal.
Have manually, the quick closing valve stop valve of pneumatic two kinds of operating method, it is by cylinder assembly, shut-off valve assemblies forms, described cylinder assembly is by left end cap, round nut, cylinder block, O-ring seals, piston, O-ring seals, right end cap, piston rod forms, described shut-off valve assemblies is by hexagon nut, plain washer, handwheel, valve rod, top cover, screw, stop nut, the collar, screw, valve gap, dust ring, gland nut, Compress Spring, bolt, hexagon nut, check washer, valve disc, valve seat, valve body forms, its improvements are: at described cylinder assembly left end, increased manual translation operating device, described manual translation operating device is by small handwheel, straight pin, manual joystick, position limit pin forms.
The central axis of the central axis of described cylinder assembly inner piston rod and shut-off valve assemblies upper valve rod is perpendicular.
On the central axis of described cylinder assembly inner piston rod and manual translation operating device, the central axis of manual joystick is coaxial.
Described piston rod left end internal thread and manual joystick right-hand member external thread diameter, pitch, rotation direction are identical, and coordinate and tighten.
In described cylinder assembly, between left end cap, round nut, increase spring, the left end of left end cap increases spacing straight trough, and spring is Compress Spring.
The present invention compared with prior art, has following good effect:
1. simple in structure, easy to manufacture;
2. can to stop valve, carry out quick closedown operation by manual, pneumatic two kinds of operating method.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is manual joystick of the present invention, position limit pin, left end cap connection part A-A profile.
Fig. 3 is manual joystick of the present invention, piston rod thread connection part B-B profile.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Shown in the drawings have manually, the quick closing valve stop valve of pneumatic two kinds of operating method, it is by cylinder assembly, shut-off valve assemblies forms, described cylinder assembly is by left end cap 5, round nut 7, cylinder block 8, O-ring seals 9, piston 10, O-ring seals 11, right end cap 12, piston rod 13 forms, described shut-off valve assemblies is by hexagon nut 14, plain washer 15, handwheel 16, valve rod 17, top cover 18, screw 19, stop nut 20, the collar 21, screw 22, valve gap 23, dust ring 24, gland nut 25, Compress Spring 26, bolt 27, hexagon nut 28, check washer 29, valve disc 30, valve seat 31, valve body 32 forms, at described cylinder assembly left end, increased manual translation operating device, described manual translation operating device is comprised of small handwheel 1, straight pin 2, manual joystick 3, position limit pin 4.
The central axis of the central axis of cylinder assembly inner piston rod 13 and shut-off valve assemblies upper valve rod 17 is perpendicular.
On the central axis of cylinder assembly inner piston rod 13 and manual translation operating device, the central axis of manual joystick 3 is coaxial.
Piston rod 13 left end internal threads and manual joystick 3 right-hand member external thread diameters, pitch, rotation direction are identical, and coordinate and tighten.
In cylinder assembly, between left end cap 5, round nut 7, increase spring 6, the left end of left end cap 5 increases spacing straight trough, and spring 6 is Compress Spring.
The specific operation of the present embodiment are as follows:
(1) adopt pneumatic mode:
If need stop valve in opening state, manually upwards mention valve rod 17, make stop nut 20 lower end surfaces 20.1 higher than piston rod 13 Up Highway UHWs, piston rod in cylinder assembly 13 is stretched out, block the stop nut 20 on valve rod 17, valve rod cannot be downward like this, and stop valve is just in opening state; As need quick closedown, and only need cylinder assembly that piston rod 13 is return, under Compress Spring 26 effects, valve rod 17 moves down rapidly, and valve disc 30 and the rapid note of valve seat 31 close, and stop valve is just in closed condition.
(2) adopt manual mode:
If cylinder medium power medium occurs extremely or not adopting pneumatic mode, can realize through the following steps unlatching and the quick closedown of stop valve:
1) cut off entering of drive unit dynamic medium (hydraulic oil or gas);
2) open valve 5.1 and the valve 12.1 at cylinder two ends, cylinder inner cavity is in communication with the outside, discharge the gas of cylinder inner cavity;
3) if need stop valve in opening state, manually upwards mention valve rod 17, then rotate small handwheel 1, forward position limit pin 4 to substantially horizontal (shown in figure mono-), under the effect of spring 6, position limit pin 4 falls into the straight trough of left end cap 5 left ends, at this moment piston rod 13 stretches out under the effect of spring 6, block the stop nut 20 on valve rod 17, valve rod cannot be downward like this, and stop valve is just in opening state;
4) as needed stop valve quick closedown, pull small handwheel 1 left, position limit pin 4 is pulled out to the straight trough of left end cap 5, rotation small handwheel 1 goes to vertical position by position limit pin 4, unclamp small handwheel 1, under the effect of spring 6, position limit pin 4 leaves on the left side of left end cap 5, and at this moment piston rod 13 is retracted, under Compress Spring 26 effects, valve rod 17 moves down rapidly, and valve disc 30 and the rapid note of valve seat 31 close, and stop valve is just in closed condition.
The present invention is simple in structure, can to stop valve, carry out the operation of quick closedown by manual, pneumatic two kinds of operating method.
