Description
Technical field
The present invention relates to a kind of valve, particularly auto-manual hinge type pneumatic control valve.
Background technology
Operated pneumatic valve be often referred to the closure of valve or regulatory function to be the controling power that produced by compressed air to realize.Its
Feature is to be swift in response, and really, it is smaller to be frequently used in valve aperture, system requirements switching speed live position faster for valve level
Put.
Operated pneumatic valve is a kind of conventional valve, is widely used in oil, in chemical pipeline.The operation of operated pneumatic valve is necessary
Require to carry out under conditions of bleed pressure is stable, if due to various accidents (such as fire) cause source of the gas catastrophic failure when,
Operated pneumatic valve just will not continue to work, and the valve element on valve rod can not continue to control the break-make of valve port, if by logical in valve body
Crossing medium is the inflammable medium such as oil, natural gas, will result in very serious consequence.Therefore, for tackling various emergency case, gas
Movable valve is generally fitted provided with hand-operating device.
Chinese patent 201120535849.0 discloses a kind of security control driving means of operated pneumatic valve, and its structure is:
A kind of security control driving means of operated pneumatic valve, the cylinder opened including valve with for control valve or close, described
It is characterised in that also including Non-follow control assembly, described Non-follow control assembly includes worm gear and worm screw, institute to cylinder connecting valve
State worm gear connecting valve, worm screw connects worm gear.The top of described worm screw is provided with handwheel.
Although above-mentioned technology solves the problems, such as that during source of the gas catastrophic failure, valve cannot normally use, manual operation needs
The elastic force of spring in the cylinder of operated pneumatic valve to be overcome, has that opening and closing resistance is big, and wasting time and energy, it is not enough to wait, and occurs promptly
During situation, easily cause loss and security incident.
Content of the invention
It is an object of the invention to provide during a kind of inefficacy in source of the gas valve rod remain to application valve body break-make hinge type pneumatic
Valve.
In order to solve the above problems, the technical scheme is that
Auto-manual hinge type pneumatic control valve, including valve body, push rod, film head and support, be provided with valve body valve seat and with
The valve element that valve seat matches, valve element upper end is closely coupled with valve rod lower end, is provided with spring, film head lower end and push rod upper end in film head
Be connected, be provided with scale above support, also include at least one four-bar linkage structure, described four-bar linkage structure one end pass through hinge axis with
Valve rod upper end couples, and its opposite end is coupled with push rod lower end by hinge axis.When personal operation hand wheel rotating, by adjusting spiral shell
Bar transfers force to hinge axis, and hinge axis drive flap to move, because push rod is difficult in the presence of film head inner spring bounce
To shift, ovable valve stem therefore can only be carried to move up and down, and then cause valve element to move up and down, realize the on-off function of valve body.Due to
It is not required to consider spring force during operation, only need to overcome the weight of valve rod and valve element, therefore, one can time saving and energy saving operate.
Further, the side hinge axis of the described hinge axis being connected with valve rod are connected with adjusting screw rod one end, adjusting screw rod
The other end is connected with handwheel, because there being handwheel to assist, increased moment, thus easy to operate.
Further, one end of the described hinge axis being connected with valve rod upper end is connected with pointer, and pointer points to above support
Scale, pointer move up and down the size that can really reflect hinge axial displacement, and then can determine whether out spool displacement size, from
And judge the break-make degree of valve body, provide facility for producing.
Further, described adjusting screw rod before and after be respectively provided on two sides with symmetrical four-bar linkage structure, described two
Symmetrical four-bar linkage structure is passed through hinge axis and is connected with adjusting screw rod rotation, using this kind of structure, is difficult during hinge opening and closing
Produce skew, increased the stability of valve.
The beneficial effect of the auto-manual hinge type pneumatic control valve of the present invention is: it is one that collection automatically controls with manual operation
Body, and manual operation is laborsaving rapidly, only needs one man operation, reduces when there is emergency, regulating valve automatically controls inefficacy and needs
Want manual operation and the loss causing that wastes time, improve safety, in terms of large-scale pneumatic formula regulating valve, effect is particularly bright
Aobvious.

Specific embodiment
By specific embodiment, the auto-manual hinge type pneumatic control valve of the present invention is made into one below in conjunction with the accompanying drawings
The explanation of step.
As shown in Fig. 1 and Fig. 3, auto-manual hinge type pneumatic control valve, including valve body 1, valve seat 2, valve element 3, valve rod 4,
Push rod 5, spring 6, film head 7, four-bar linkage structure, pointer 9, scale 10, handwheel 11, adjusting screw rod 12 and support 14, double leval jib is tied
Structure includes flap 13 and hinge axis 8, and four-bar linkage structure one end is coupled with valve rod 4 upper end by hinge axis 8, and its opposite end is passed through
Hinge axis 8 are coupled with push rod 5 lower end.Wherein, it is provided with valve seat 2 and the valve element 3 matching with valve seat 2, valve element 3 in described valve body 1
Upper end is closely coupled with valve rod 4 lower end.Wherein, described push rod 5 upper end is connected with film head 7, is provided with spring 6 in film head 7.Wherein,
Described pointer 9 one end is connected with hinge axis 8, and the scale 10 above support 14 is pointed in one end.Wherein, described handwheel 11 passes through to adjust
Screw rod 12 is connected with hinge axis 8.
During normal work, as shown in figure 1, passing through adjusting handle 11, adjusting screw rod 12 is driven to make push rod 5 and valve rod 4 spacing
Maximum, when compressed air enters membrane head 7, spring 6 compresses or extends, drive push rod 5, hinge axis 8, flap 13, handwheel 11,
Adjusting screw rod 12, pointer 9, valve rod 4 and valve element 3 are up and down, realize the regulation on-off function of the present invention.
When source of the gas breaks down, the present invention automatically control cannot normal switching-off or when opening, as shown in Fig. 2 adjusting handss
Wheel 11, drives adjusting screw rod 12 to rotate, adjusting screw rod 12 transfers force on hinge axis 8, and hinge axis 8 drive flap to move,
Because push rod 5 is difficult to shift in the presence of film head 7 inner spring 6 bounce, ovable valve stem 4 therefore can only be carried to move up and down, and then
Cause valve element 3 to move up and down, realize the on-off function of valve body 1.It is not required to overcome spring force due to during operation, only need to overcome valve rod
With the weight of valve element, more there is handwheel to assist, increased moment, therefore, one can time saving and energy saving operate, and can be prevented effectively from production thing
Therefore.
The foregoing is only the specific embodiment of the present invention, but the architectural feature of the present invention is not limited thereto, the present invention
Can be used on similar product, in the field of the invention, the change made or modification are all for any those skilled in the art
Cover among the scope of the claims of the present invention.
