Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an anti-slip valve. Background Art

[0002] A valve is a device used to control media such as gas, liquid, and gas or liquid containing solid powder in various pipelines and equipment; a valve is usually composed of a valve body, a valve cover, a valve seat, an opening and closing member, a driving mechanism, a seal and fasteners; the control function of the valve is achieved by relying on the driving mechanism or fluid to drive the opening and closing member to rise and fall, slide, swing or rotate at a ratio to change the size of the flow area.

[0003] Please refer to the patent number CN213018029U for an anti-slip pneumatic valve manual mechanism. The patent states that "the existing pneumatic valve manual equipment cannot perform anti-slip treatment well when rotating, which affects the efficiency of rotation. In addition, the center of the threaded rod is too long when rotating, which reduces the service life of the threaded rod." The patent provides a centering device to support the threaded rod in a centering manner, so as to avoid the threaded rod from shifting when rotating, thereby avoiding wear on the threads on the threaded rod, thereby increasing the service life of the threaded rod and also playing a centering role.

[0004] However, although the centering device provided in the above patent can reduce the displacement during the rotation of the threaded rod, the second bearing and the first bearing in its positioning device are connected to the threaded rod through internal threads. When the threaded rod rotates, the threads inside the bearings will produce sliding friction with the outer threads of the threaded rod, causing wear of the threads. Long-term use can easily lead to a decrease in the degree of centering, and the practicality is poor. In view of this, the present application proposes an anti-slip valve. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an anti-slip valve, which can prevent hands from falling off or slipping while conveniently controlling the rotation of the threaded rod. In addition, the threaded rod can be supported in two different ways for centering, thereby effectively reducing the deviation of the threaded rod during rotation, reducing the wear of the threads on the threaded rod, and extending its service life. It solves the problem that the existing pneumatic valve manual equipment cannot perform good anti-slip treatment during rotation, thereby affecting the rotation efficiency. In addition, the threaded rod is too long when rotating and the center is easily offset, thereby reducing the service life of the threaded rod.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-slip valve, comprising a valve body, a centering adjustment mechanism is provided on the top of the valve body;

[0007] The centering adjustment mechanism comprises a threaded rod movably connected inside the valve body, a fixing frame is fixedly connected to the top of the valve body, a movable plate is slidably connected inside the fixing frame, a centering rod corresponding to the position of the movable plate is fixedly connected to the top of the threaded rod, a centering bearing is fixedly connected to the side opposite to the movable plate and the centering rod, and a sliding rod is fixedly connected to the top of the centering rod;

[0008] A turntable is slidably connected to the top of the fixed frame, a limit slider slidably connected to the slide rod is fixedly connected to the inner side of the turntable, a plurality of connection blocks are fixedly connected to the top of the turntable, and a handle is fixedly connected to the side of the connection block away from the turntable.

[0009] Furthermore, the fixing frame is in an inverted U shape, and flanges are fixedly connected to both left and right ends of the valve body.

[0010] Furthermore, the left and right sides of the movable plate are fixedly connected with shifting slide blocks extending into the interior of the fixing frame, and the inner side of the fixing frame is provided with shifting slide grooves slidably matched with the shifting slide blocks.

[0011] Furthermore, a sliding lining slidably matched with the sliding rod is fixedly connected to the interior of the fixing frame, and a limiting sliding groove slidably matched with the limiting sliding block is provided inside the sliding rod.

[0012] Furthermore, a limiting ring is fixedly connected to the bottom of the turntable, and a limiting groove slidably matched with the limiting ring is formed on the top of the fixing frame.

[0013] Furthermore, the connection blocks are arranged at an angle, and are evenly arranged in a circular shape on the top of the turntable, and the handle is a U-shaped structure.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The anti-slip valve can be driven by holding the handle to rotate the turntable on the fixed frame, so that the turntable can use the limit slider to drive the sliding rod to rotate, thereby realizing the rotation adjustment of the centering rod and the threaded rod, thereby avoiding the hand from falling off when controlling the rotation of the turntable, and effectively preventing slipping; in this process, the movable plate can cooperate with the centering bearing to limit the movement of the centering rod, so as to cooperate with the setting of the sliding liner to realize the centering support of the threaded rod, thereby effectively reducing the deviation of the threaded rod during rotation, reducing the wear of the thread on the threaded rod, and extending its service life; enhancing the practical effect of the device.
