Abstract
The utility model provides a duplex valve structure, which comprises a connecting pipe, three-way ball valves arranged at two ends of the connecting pipe, a connecting shaft positioned in the connecting pipe, a worm wheel and a worm which are meshed with each other, and a hand wheel for driving the worm; the connecting shaft is connected with a valve rod of the three-way ball valve, and the worm wheel is arranged on the connecting shaft. The utility model provides a pair valve structure can drive even axle through the worm gear and worm and rotate, utilizes even axle to drive two synchronous rotations of valve rod to can realize opening simultaneously or close two tee bend ball valves fast high-efficiently, satisfy the technological process demand.
Description
Technical Field
The utility model relates to the technical field of valves, especially, relate to a pair valve structure.
Background
The valve is a device that can control the flow rate of a medium (liquid, gas, powder) in a pipe or equipment by flowing or stopping the medium. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valve is a control part in a pipeline fluid conveying system, is used for changing the section of a passage and the flowing direction of a medium, and has the functions of diversion, cut-off, throttling, non-return, flow splitting, overflow pressure relief and the like.
The manual valve has the advantages of simple structure, simple operation, low cost and price and the like, but the manual valve needs to be opened or closed by one valve, which is relatively troublesome, in addition, the two valves are opened and closed independently, which has time errors, can not be performed simultaneously and rapidly, and sometimes can easily influence the process flow, such as simultaneous feeding and the like. In view of the above, there is a need for a valve structure to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to disclose a pair valve structure can drive even axle through the worm gear and worm and rotate, utilizes even axle to drive two valve rod synchronous rotations to can realize opening simultaneously fast high-efficiently or close two tee bend ball valves, satisfy the process flow demand.
In order to achieve the purpose, the utility model provides a duplex valve structure, which comprises a connecting pipe, three-way ball valves arranged at two ends of the connecting pipe, a connecting shaft positioned in the connecting pipe, a worm wheel and a worm which are meshed with each other, and a hand wheel for driving the worm; the connecting shaft is connected with a valve rod of the three-way ball valve, and the worm wheel is arranged on the connecting shaft.
In some embodiments, the device further comprises a housing mounted on the adapter, the worm gear and worm being located within the housing.
In some embodiments, the nipple and the three-way ball valve are connected by a first flange, and the nipple and the housing are connected by a second flange.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a pair valve structure can drive even axle through the worm gear and worm and rotate, utilizes even axle to drive two synchronous rotations of valve rod to can realize opening simultaneously or close two tee bend ball valves fast high-efficiently, satisfy the technological process demand.
Drawings
Fig. 1 is a schematic structural diagram of the double valve structure of the present invention.
Detailed Description
The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.
The duplex valve structure shown in fig. 1 comprises a connecting pipe 2, three-way ball valves 1 arranged at two ends of the connecting pipe 2, a connecting shaft 3 positioned in the connecting pipe 2, a worm wheel (not shown) and a worm (not shown) which are meshed with each other, and a hand wheel 5 for driving the worm.
The connecting shaft 3 is connected with a valve rod of the three-way ball valve 1, and the worm wheel is installed on the connecting shaft 3. And the device also comprises a shell 6 arranged on the connecting pipe 2, and the worm wheel and the worm are positioned in the shell 6. The connecting pipe 2 is connected with the three-way ball valve 1 through a first flange 41, and the connecting pipe 2 is connected with the shell 6 through a second flange 42.
The rotating hand wheel 5 drives the worm, the worm drives the worm wheel to rotate, the worm wheel drives the connecting shaft 3 to rotate, and the connecting shaft 3 drives the two valve rods to synchronously rotate, so that the two three-way ball valves 1 can be opened or closed quickly and efficiently at the same time, and the requirements of the process flow are met.
The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
