Abstract
The invention discloses a valve component with an anti-rotation structure, which comprises a valve body, a valve rod and an anti-rotation sleeve, wherein the valve rod and the anti-rotation sleeve are arranged on the valve body; the anti-rotation valve is characterized in that the anti-rotation sleeve is arranged on the valve body, and the valve rod is arranged in the valve body through the anti-rotation sleeve; a gear is arranged on the valve rod, and a tooth socket matched with the gear is arranged on the anti-rotating sleeve; the valve rod is connected with the anti-rotation sleeve in a sliding mode through the matching of the gear and the tooth grooves. According to the invention, the gear is arranged on the valve rod, the anti-rotation sleeve is arranged on the valve body, the tooth socket matched with the gear is arranged on the anti-rotation sleeve, and the valve rod is prevented from rotating when the valve rod reciprocates up and down through the adjusting thread through the matching of the gear and the tooth socket, so that the problem that the valve cannot move up and down due to the rotation of the valve rod is avoided, and the valve cannot be normally used.
Description
Technical Field
The utility model relates to a valve specifically indicates a valve component with anti-rotation structure.
Background
The opening and closing part of the stop valve is a plug-shaped valve clack, the upper surface of the seal is a plane or a sea cone surface, and the valve clack moves linearly along the central line of the valve seat. The valve rod can move in a mode (the general name is a hidden rod) or in a lifting rotating rod mode, and can be used for controlling the flow of various types of fluid such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like; the lifting screw rod drives the valve rod to move up and down by rotating the nut through the matching of the nut and the thread on the valve rod, but the valve rod is easily driven to rotate together with the nut when the nut is rotated, so that the valve rod cannot move up and down, and the valve cannot be normally used; therefore, many enterprises have designed a lot of designs in order to prevent the valve rod from rotating, and the rotation of the valve rod is limited by the rotation prevention sleeve through installing the rotation prevention sleeve on the valve body, so that the general rotation prevention sleeve needs a special tool to be assembled, and is very troublesome. To this end, a valve assembly having an anti-rotation structure is proposed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problems and providing a valve component with an anti-rotation structure.
In order to achieve the purpose, the utility model provides a valve component with an anti-rotation structure, which comprises a valve body, a valve rod arranged on the valve body and an anti-rotation sleeve; the anti-rotation valve is characterized in that the anti-rotation sleeve is arranged on the valve body, and the valve rod is arranged in the valve body through the anti-rotation sleeve; a gear is arranged on the valve rod, and a tooth socket matched with the gear is arranged on the anti-rotating sleeve; the valve rod is connected with the anti-rotation sleeve in a sliding mode through the matching of the gear and the tooth grooves.
Further preferably, an internal thread is arranged in the valve body, an external thread matched with the internal thread is arranged on the anti-rotation sleeve, and the anti-rotation sleeve is installed in the valve body through the thread.
Preferably, a valve core is installed at one end of the valve rod, and an adjusting thread is arranged at the other end of the valve rod.
The utility model discloses a set up the gear on the valve rod, install the rotation-proof cover on the valve body, and set up the tooth's socket with gear looks adaptation on the rotation-proof cover, through the cooperation of gear and tooth's socket, prevent the valve rod when the valve rod carries out up-and-down motion through adjusting the screw thread and rotate, avoid the valve rod to rotate and lead to unable up-and-down motion that carries on to make the unable normal use of valve.
