The quick-closing stop valve solves the problem that the quick closing of the stop valve is affected because of abnormal power medium in an air cylinder of the existing pneumatic quick-closing stop valve, has the characteristics of simple structure and easiness in manufacture, can be quickly closed through manual and pneumatic operation methods, and is applicable to pneumatic quick-closing stop valves.
Description
Technical field
The utility model relates to a kind of stop valve, and specifically, the utility model relates to a kind of pneumatic quick closing valve stop valve.
Background technique
Hand stop valve generally is to realize moving up and down of valve rod by the screw thread on the valve rod, thereby realizes closing and opening of valve, and is very slow when the stop valve of this structure is closed.For realizing the quick closedown of stop valve, the quick closing valve stop valve of air cylinder driven has appearred on the market adopting, and the pneumatic quick closing valve stop valve of prior art is in the valve gap side cylinder assembly to be set, and increases Compress Spring between valve gap and valve disc.If need stop valve to be in opening state, then piston rod stretches out in the cylinder assembly, blocks the stop nut on the valve rod, and valve rod can't be downward like this, and stop valve just is in opening state; Such as the need quick closedown, only need cylinder assembly that piston rod is return, under the Compress Spring effect, valve rod moves down rapidly, and the rapid note of valve disc and valve seat closes, and stop valve just is in closed condition.This pneumatic quick closing valve stop valve has simple in structure, closes rapidly characteristics.If but the appearance of cylinder medium power medium is unusual, piston rod can't normally stretch, and also just can't realize the quick closedown of stop valve.
The model utility content
The utility model is for the deficiencies in the prior art, proposes a kind of simple in structurely, can solve stop valve quick closedown problem appears unusually affecting in existing pneumatic quick closing valve stop valve because of cylinder medium power medium pneumatic quick closing valve stop valve.
The utility model 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: increased the manual translation operating device at described cylinder assembly left end, 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.
The central axis of manual joystick is coaxial on the central axis of described cylinder assembly inner piston rod and the manual translation operating device.
Described piston rod left end internal thread and manual joystick right-hand member external thread diameter, pitch, rotation direction are identical, and cooperate and tighten.
Increase spring between left end cap, the round nut in the described cylinder assembly, the left end of left end cap increases spacing straight trough, and spring is Compress Spring.
The utility model compared with prior art has following good effect:
1. simple in structure, easy to manufacture;
2. can carry out the quick closedown operation to stop valve with manual, pneumatic two kinds of operating method.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A profile among Fig. 1.
Fig. 3 is the B-B profile among Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the 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, and 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; Increased the manual translation operating device at described cylinder assembly left end, 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.
The central axis of manual joystick 3 is coaxial on the central axis of cylinder assembly inner piston rod 13 and the manual translation operating device.
Piston rod 13 left end internal threads and manual joystick 3 right-hand member external thread diameters, pitch, rotation direction are identical, and cooperate and tighten.
Increase spring 6 in the cylinder assembly between left end cap 5, the round nut 7, the left end of left end cap 5 increases spacing straight trough, and spring 6 is Compress Spring.
The specific operation of present embodiment are as follows:
(1) adopt pneumatic mode:
If need stop valve to be in opening state, manually upwards mention valve rod 17, make stop nut 20 lower end surfaces 20.1 be higher than piston rod 13 Up Highway UHWs, piston rod in the cylinder assembly 13 is stretched out, block the stop nut 20 on the valve rod 17, valve rod can't be downward like this, and stop valve just is in opening state; Such as the need quick closedown, 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 valve seat 31 rapid notes close, and stop valve just is in closed condition.
(2) adopt manual mode:
If cylinder medium power medium occurs unusually or not adopting pneumatic mode, can realize through the following steps unlatching and the quick closedown of stop valve:
1) cuts 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 to be in opening state, manually upwards mention valve rod 17, then rotate small handwheel 1, forward position limit pin 4 to substantially horizontal (shown in the figure one), 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 the valve rod 17, valve rod can't be downward like this, and stop valve just is in opening state;
4) such as the quick closedown of need stop valve, spur small handwheel 1 left, position limit pin 4 is pulled out the straight trough of left end cap 5, rotation small handwheel 1 goes to the vertical position with 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 valve seat 31 rapid notes close, and stop valve just is in closed condition.
The utility model is simple in structure, can carry out by manual, pneumatic two kinds of operating method the operation of quick closedown to stop valve.
