Description

Technical Field

[0001] The utility model relates to the field of valve handwheels, in particular to a quick-opening valve handwheel. Background Art

[0002] At present, the valve handwheel is a component arranged outside the valve body to connect the valve core and control the rotation of the valve core. The outer edge of the existing handwheel body is a flat arc. When turning the handwheel body, both hands are prone to slipping along the rotation direction. At the same time, the presence of the plastic layer makes the surface of the handwheel body smoother, resulting in the operator being unable to grasp the handwheel body tightly, and the entire rotation process is relatively strenuous. The crank on the handwheel is mostly integrally formed and cannot be disassembled, which affects the use feel when the crank is not needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quick-opening valve handwheel aiming at the above deficiencies.

[0004] The utility model includes a hub and a rim. The hub is fixed at the center of the rim through a pair of spokes. A shaft hole is opened on the hub, and a pair of anti-slip protrusions are symmetrically distributed on the inner wall of the rim.

[0005] The shaft hole is an oblong hole.

[0006] Threaded holes are opened on the outer wall of the hub, and locking screws are screwed into the threaded holes to fix the hub on the top of the valve stem.

[0007] Multiple groups of anti-slip patterns are arranged on the outer wall of the rim.

[0008] A group of arc-shaped anti-slip protrusions are annularly and evenly arranged on the top of the rim.

[0009] A cylindrical protrusion is arranged at the connection between the spoke and the rim. An installation hole is opened at the center of the cylindrical protrusion, and a crank is arranged in the installation hole.

[0010] The crank is cylindrical.

[0011] A screw rod is arranged at the bottom of the crank and is threadedly installed in the installation hole of the cylindrical protrusion through the screw rod.

[0012] Reinforcing ribs are respectively arranged on both sides at the connection between the spoke and the rim.

[0013] A pair of spokes and a pair of anti-slip protrusions are arranged in a cross-cross manner.

[0014] The advantages of the utility model are as follows:

[0015] 1. The overall structure of the handwheel is simple. A pair of spokes are used to connect the hub and the rim, and the rotation feel is good.

[0016] 2. The handwheel is not prone to slipping when rotating.

[0017] 3. The crank can be detached and installed as needed. Description of the Drawings

[0025] As shown in the attached drawings, the utility model includes a hub 101 and a rim 102. The hub 101 is fixed at the center of the rim 102 through a pair of spokes 103. A shaft hole 104 is formed on the hub 101, and a pair of anti-slip protrusions 105 are symmetrically distributed on the inner wall of the rim 102.

[0026] The shaft hole 104 is an oblong hole.

[0027] Threaded holes are formed on the outer wall of the hub 101. Locking screws are screwed into the threaded holes to fix the hub 101 on the top of the valve stem.

[0028] Multiple groups of anti-slip patterns are arranged on the outer wall of the rim 102.

[0029] A group of arc-shaped anti-slip protrusions 106 are evenly distributed in a ring at the top of the rim 102.

[0030] A cylindrical protrusion 108 is arranged at the connection between the spoke 103 and the rim 102. An installation hole is formed at the center of the cylindrical protrusion 108, and a crank 107 is arranged in the installation hole.

[0031] The crank 107 is cylindrical.

[0032] A screw rod is arranged at the bottom of the crank 107, and the crank 107 is threadedly installed in the installation hole of the cylindrical protrusion 108 through the screw rod.

[0033] Reinforcing ribs are respectively arranged on both sides at the connection between the spoke 103 and the rim 102.

[0034] A pair of spokes 103 and a pair of anti-slip protrusions 105 are arranged in a cross.

[0035] Embodiment 1: The upper cross-section of the valve stem of the valve is an oblong shape matching the shaft hole 104. The hub 101 is installed on the valve stem. If long-term installation is required, the locking screw is screwed into the threaded hole on the outer wall of the hub 101 to press against the outer wall of the valve stem to complete the fixation. When the handwheel is installed on the side valve, the crank 107 can be installed in the installation hole of the cylindrical protrusion 108, and the handwheel can be driven to rotate through the crank. When starting to rotate the handwheel, the anti-slip protrusion 105 blocks the staff's hand to avoid slipping. At the same time, the arc-shaped anti-slip protrusion 106 and the anti-slip patterns can both play an auxiliary role in avoiding slipping.
