Description
Technical field
The present invention relates to a kind of valve, particularly auto-manual hinge type pneumatic control valve.
Background technique
Pneumatic valve is often referred to the closed of valve or regulatory function is that the control force produced by pressurized air realizes.Be characterized in being swift in response, valve position is accurate, is often used in valve aperture smaller, system requirements switching speed field position faster.
Pneumatic valve is a kind of conventional valve, is widely used in oil, chemical pipeline.The operation of pneumatic valve necessarily requires to carry out under the stable condition of bleed pressure, if due to various accident (such as fire) cause source of the gas catastrophic failure time, pneumatic valve just can not work on, spool on valve rod can not continue the break-make controlling valve port, if by being the inflammable medium such as oil, rock gas by medium in valve body, very serious consequence will be caused.Therefore, for tackling various emergency case, pneumatic valve is generally all equipped with hand-operating device.
Chinese patent 201120535849.0 discloses a kind of safety control drive unit of pneumatic valve, its structure is: a kind of safety control drive unit of pneumatic valve, the cylinder comprising valve and open for control valve or close, described cylinder connects valve, it is characterized in that, also comprise Non-follow control assembly, described Non-follow control assembly comprises worm gear and worm screw, described worm gear connects valve, and worm screw connects worm gear.The top of described worm screw is provided with handwheel.
The problem that when although above-mentioned technology solves source of the gas catastrophic failure, valve cannot normally use, but manually-operable needs the elastic force of the cylinder medi-spring overcoming pneumatic valve, have that to open and close resistance large, waste time and energy and wait deficiency, when there is urgency, easily cause damage and security incident.
Summary of the invention
The object of the present invention is to provide that a kind of valve rod still can the hinge type pneumatic valve of control valve body break-make when source of the gas loses efficacy.
In order to solve the problem, technological scheme of the present invention is:
Auto-manual hinge type pneumatic control valve, comprise valve body, push rod, film head and support, the spool being provided with valve seat in valve body and matching with valve seat, spool upper end is closely connected with valve rod lower end, is provided with spring in film head, and film head lower end is connected with push rod upper end, scale is provided with above support, also comprise at least one four-bar linkage structure, described four-bar linkage structure one end is connected with valve rod upper end by hinge axis, and its opposite end is connected with push rod lower end by hinge axis.When individual operates hand wheel rotating, by adjusting screw rod, power is delivered to hinge axis, hinge axis drives hinge plate to move, because push rod is difficult to displacement under the effect of film head inner spring rebounding force, therefore ovable valve stem can only be with to move up and down, and then cause spool to move up and down, realize the on-off function of valve body.Owing to not needing to consider spring force during operation, only need overcome the weight of valve rod and spool, therefore, singlely can time saving and energy savingly operate.
Further, described in be connected with the hinge axis of valve rod side hinge axis be connected with adjusting screw rod one end, the adjusting screw rod the other end is connected with handwheel, because there being handwheel to assist, adds moment, so easy to operate.
Further, one end of the described hinge axis be connected with valve rod upper end is connected with pointer, scale above pointed support, pointer move up and down the size that can reflect hinge axis displacement really, and then spool travel size can be judged, thus judge the break-make degree of valve body, provide convenient for producing.
Further, the both sides, front and back of described adjusting screw rod are respectively equipped with symmetrical four-bar linkage structure, and described two symmetrical four-bar linkage structures are rotationally connected by hinge axis and adjusting screw rod, use this kind of structure, not easily produce skew during hinge opening and closing, add the stability of valve.
The beneficial effect of auto-manual hinge type pneumatic control valve of the present invention is: integrate and automatically control and manually-operable, and manually-operable is laborsaving rapidly, only need one man operation, reduce when there is urgency, modulating valve controls to lose efficacy to need manually-operable and the loss caused that wastes time automatically, improve Security, in large-scale pneumatic formula modulating valve, act on particularly evident.

In above accompanying drawing: 1, valve body; 2, valve seat; 3, spool; 4, valve rod; 5, push rod; 6, spring; 7, film head; 8, hinge axis; 9, pointer; 10, scale; 11, handwheel; 12, adjusting screw rod; 13, hinge plate; 14 supports.
Embodiment
Auto-manual hinge type pneumatic control valve of the present invention is further described by embodiment below in conjunction with accompanying drawing.
As shown in Fig. 1 and Fig. 3, auto-manual hinge type pneumatic control valve, comprise valve body 1, valve seat 2, spool 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, four-bar linkage structure comprises hinge plate 13 and hinge axis 8, four-bar linkage structure one end is connected with valve rod 4 upper end by hinge axis 8, and its opposite end is connected with push rod 5 lower end by hinge axis 8.Wherein, the spool 3 being provided with valve seat 2 in described valve body 1 and matching with valve seat 2, spool 3 upper end is closely connected 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 is connected with hinge axis 8 by adjusting screw rod 12.
During normal work, as shown in Figure 1, by adjusting handle 11, drive adjusting screw rod 12 make push rod 5 and valve rod 4 spacing maximum, when pressurized air turnover film head 7, spring 6 compresses or extends, and drives push rod 5, hinge axis 8, hinge plate 13, handwheel 11, adjusting screw rod 12, pointer 9, valve rod 4 and spool 3 up and down, realizes adjustment on-off function of the present invention.
When source of the gas breaks down, when the present invention controls normally to close or to open automatically, as shown in Figure 2, adjusting handle 11, drives adjusting screw rod 12 to rotate, power is delivered on hinge axis 8 by adjusting screw rod 12, hinge axis 8 drives hinge plate to move, and because push rod 5 is difficult to displacement under the effect of film head 7 inner spring 6 rebounding force, ovable valve stem 4 therefore can only be with to move up and down, and then cause spool 3 to move up and down, realize the on-off function of valve body 1.Do not need to overcome spring force due to during operation, only need overcome the weight of valve rod and spool, more have handwheel to assist, add moment, therefore, singlely time saving and energy savingly can to operate, effectively can avoid production accident.
The foregoing is only specific embodiments of the invention, but structure characteristic of the present invention is not limited thereto, the present invention may be used on similar product, and any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
