Abstract
The invention discloses a multi-blade natural gas pipeline control valve. The valve comprises a square valve body. The valve further comprises two or more control blades. Each control blade comprises two valve plates arranged in a stagger mode. A connecting shaft is arranged at each of the two ends of each control blade and is connected with the square valve body in a rotary mode. The distance between every two adjacent connecting shafts is equal to the width of each valve plate. The valve has the advantages that the multiple control blades are arranged, operation can be achieved effortlessly, and sealing effect is good; meanwhile, connecting rods and connecting plates are arranged, the multiple control blades can be controlled synchronously to rotate, and using is convenient.
Description
Technical field
The present invention relates to a kind of control valve of natural gas pipeline, more precisely a kind of Multi-vane type natural gas pipe-line control valve.
Background technique
The diameter of large-scale natural gas pipeline is comparatively large, and the pressure of its inside is also comparatively large, and the size of the valve body of the control valve that this pipeline is installed is larger, because moment of torsion is larger during opening and closing, comparatively require great effort, and sealing effect between the edge of valve plate and valve body is bad, easily reveals.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provide a kind of with multiple control blade, rapid operation, and sealing effect is better, simultaneously with connecting rod and connecting plate, can the multiple control blade rotation of synchronization control, Multi-vane type natural gas pipe-line control valve easy to use.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of Multi-vane type natural gas pipe-line control valve, comprise a square valve body, described Multi-vane type natural gas pipe-line control valve also comprises plural control blade, described control blade comprises the valve plate that two mutual dislocation are arranged, the two ends of described control blade are respectively arranged with a coupling shaft, described coupling shaft and described square valve body are rotationally connected, and the spacing between two adjacent coupling shafts equals the width of described valve plate.
As preferred embodiment of the present invention, described Multi-vane type natural gas pipe-line control valve also comprises a control handwheel, a connecting rod and the connecting plate equal with described control blade quantity, described control handwheel is fixedly connected with described coupling shaft, one end of described connecting plate is fixedly connected with described coupling shaft, and the other end and described connecting rod are rotationally connected.
The advantage of Multi-vane type natural gas pipe-line control valve of the present invention is: with multiple control blade, rapid operation, and sealing effect is better, simultaneously with connecting rod and connecting plate, can the multiple control blade rotation of synchronization control, and easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The advantage of Multi-vane type natural gas pipe-line control valve of the present invention is: with multiple control blade, rapid operation, and sealing effect is better, simultaneously with connecting rod and connecting plate, can the multiple control blade rotation of synchronization control, and easy to use.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Multi-vane type natural gas pipe-line control valve, comprise a square valve body 1, this Multi-vane type natural gas pipe-line control valve also comprises plural control blade 2, as shown in Figure 4, Figure 5, this control blade 2 comprises the valve plate 21 that two mutual dislocation are arranged, the two ends of this control blade 2 are respectively arranged with a coupling shaft 22, this coupling shaft 22 is rotationally connected with this square valve body 1, and the spacing between two adjacent coupling shafts 22 equals the width of this valve plate 21.Multiple control blade 2 can splice at a complete valve plate by rotating, and plays the object cutting off natural gas pipeline, this control blade 2 also can be made to form multiple mutual connectionless structure, reaching the object connecting natural gas pipeline by rotating.Because the width of each control blade 2 is less, therefore moment of torsion is less, operates comparatively laborsaving.The valve plate 21 be staggeredly arranged can make two seams controlled between blade 2 be " Z " shape, instead of " I " shape, can prevent from revealing.
As shown in Figure 1, Figure 2, Figure 3 shows, this Multi-vane type natural gas pipe-line control valve also comprises control handwheel 3, connecting rod 4 and the connecting plate 5 equal with this control blade 2 quantity, this control handwheel 3 is fixedly connected with this coupling shaft 22, one end of this connecting plate 5 is fixedly connected with this coupling shaft 22, and the other end and this connecting rod 4 are rotationally connected.By these structures, make these control blades 2 can be synchronous rotation, easy to use, switch is quick.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
