Abstract
The utility model relates to a multifunctional control butterfly valve, which comprises a butterfly valve plate a tightly matched with a connecting flange of the butterfly valve, and the connecting flange is screwed between a water inlet pipe and a water outlet pipe. The butterfly valve plate is fixedly connected with a half gear (worm) shaft of a control device via a shaft of the butterfly valve, and the control device is composed of a half gear (worm) and a driving cog (worm) rod engaged with the half gear (worm). smooth cog rods at two ends of the driving cog (worm) rod are respectively fixedly connected with an inlet cylinder body piston in an inlet cylinder body and an outlet cylinder body piston in an outlet cylinder body, and two tail ends of each of the inlet cylinder body and the outlet cylinder body are respectively communicated with an inlet end and an outer end of the valve via pipelines. The utility model has the advantages of simple structure, low cost and convenient repair and use.
Description
Technical field
The utility model relates to a kind of control valve for fluids, i.e. the multi-functional control butterfly valve.
Background technique
At present, general tipping has outlet one-way valve, manually operated valve on the delivery side of pump pipeline, should be hinged with electronic (pneumatic) control valve if realize opening pump automatically then exporting.Because the moment of safety check closes during termination of pumping, also the water hammer cancellation element should be set.Its complex structure, investment is big and fault is many, uses inconvenient maintenance.
Summary of the invention
Its purpose of the utility model is: a kind of multi-functional control butterfly valve is provided, and it is simple in structure, and is with low cost, uses easy to maintenance.
The purpose of this utility model is achieved in that a kind of multi-functional control butterfly valve, comprise: butterfly valve plate and butterfly valve adpting flange closely cooperate, adpting flange is bolted between inlet tube and outlet tube, its butterfly valve plate is affixed by half tooth (snail) wheel shaft of butterfly valve axle and control gear, driving gear (snail) bar that its control gear is engaged with by half tooth (snail) wheel, the two ends light ratch of its driving gear (snail) bar are affixed with the import cylinder piston and the outlet cylinder piston in the outlet cylinder body of import cylinder body respectively; Import cylinder body and outlet cylinder body two ends are by pipeline difference connecting valve entrance point, valve outlet port end.Its half tooth (snail) wheel is arranged in the gear-box with tooth (snail) bar.Its control gear is fixed on butterfly valve plate and the butterfly valve shaft holder.
The utility model is the pressure reduction that utilizes water before and after the valve, slow automatically opening when realizing turn on pump, and automatic Slow Close during termination of pumping need not the self-service control valve of power of any external force, and it is simple in structure, and cost is low, and safe and reliable, uses, easy to maintenance.
Elaborate with accompanying drawing in conjunction with the embodiments:
Description of drawings
Fig. 1 the utility model structural representation.
Accompanying drawing number:
1. butterfly valve axle 2. butterfly valve plates 3. flange holes
4. butterfly valve adpting flange 5. is sought line 6. import cylinder bodies
7. import cylinder piston 8. driving gears (snail) bar 9. gear-boxes
Embodiment
Its structure of the utility model is as shown in Figure 1: a kind of multi-functional control butterfly valve, comprise: butterfly valve plate 2 closely cooperates with butterfly valve adpting flange 4, adpting flange 4 is bolted between inlet tube and outlet tube, its butterfly valve plate 2 is affixed with half tooth worm-wheel shaft of control gear by butterfly valve axle 1, the driving gear worm screw 8 that its control gear is engaged with by half tooth worm gear 10, the two ends light ratch of its driving gear worm screw 8 are affixed with the import cylinder piston 7 and the outlet cylinder piston 11 in the outlet cylinder body 12 of import cylinder body 6 respectively; 12 liang of ends of import cylinder body 6 and outlet cylinder body are by pipeline 5,13 difference connecting valve entrance points, valve outlet port end.
Its half tooth worm gear 10 is arranged in the gear-box 9 with tooth worm screw 8.
Its control gear is fixed on butterfly valve plate 2 and the butterfly valve shaft holder 14.
The butterfly valve plate 2 of described control butterfly valve, adpting flange 4 adopts Cuprum alloy, stainless steel material.Described butterfly valve mounting flange 4, half tooth (snail) wheel 10, driving gear (snail) bar 8, all adopt 45# steel, engineering plastics into and out of cylinder body 6,12.
Working procedure:
When centrifugal pump starts, the delivery side of pump end rises gradually with startup, the pressure of pump, fluid enters the entry end of import cylinder body 6 by pipeline 5, import cylinder piston 7 promotes driving gear (snail) bar 8 under the effect of fluid, driving gear (snail) bar 8 drives half gear 10 and rotates, half gear 10 drives butterfly valve axle 1, and butterfly valve axle 1 is opened butterfly valve plate 2.The size of valve opening is regulated automatically by flow, and the big valve opening of flow is big, and flow minor valve aperture is little.
When the centrifugal pump termination of pumping, flow and pressure reduce suddenly, but system pressure still exists, it is low and back-pressure that outlet end pressure is high is poor then to form this valve inlet end pressure, then the pressure of valve export end affacts in the outlet cylinder body by the pipeline 13 of valve inlet with outlet cylinder body 12, thereby promote the motion of outlet end cylinder piston and promote driving gear (snail) bar 8, driving gear (snail) thus bar 8 drives half gear 10 to rotate then half tooth axle 10 and drives butterfly valve axles 1 and butterfly valve plate 2 and rotate these butterfly valves and close.
The utility model multi-functional control butterfly valve can be installed in delivery side of pump and replace safety check, electric opening valve, autocontrol valve, manually-operated gate.Multipurpose such as also can do that water-hammer and safety check are used, it is simple in structure, and is with low cost, use, easy to maintenance, and saving power.
