Description

Ratchet valve spanner

Technical Field

The utility model relates to the technical field of valve tools, in particular to a ratchet valve spanner.

Background

In the working processes of operation, adjustment and the like of power production, F-shaped wrenches are often used for operation. The traditional F-shaped spanner is an F-shaped structural member consisting of a longitudinal main rod body and two transverse spanner rod bodies fixedly connected to the upper part of the main rod body, and a handle is arranged at the lower part of the main rod body. When the manual valve is used, the handle is held by hand, the spanner is inserted into the hand wheel of the manual valve, and the handle is pushed to switch the valve. However, in the process of operating the traditional F-shaped spanner switch valve by operators, the angle of the push handle is required to be continuously changed, after a certain distance is pushed, the direction of the grip handle is required to be changed, the grip handle is again gripped to continue to operate, the whole operation process is inconvenient, the operation efficiency is low, and the intermittent handle capable of changing the direction of the grip handle by loosening the hand sometimes falls off, so that potential safety hazards are brought. Meanwhile, in the fully-opened and fully-closed position of the valve, the valve sealing element is easy to be damaged if the operation torque is larger due to longer operation handle and improper operation. In addition, the valve has larger operating moment, and the valve switch stroke is longer, so that the valve switch time is long. The space between the two clamping rods on the F-shaped head is too large to cause the space between the hand rods to be too large when the valve is opened and closed, so that the valve spanner is not only shaken by hands but also is easy to slip and can not be used in places with narrow space. Not only reduces the working efficiency of operators, but also causes injury to the operators when serious, and has certain potential safety hazard. Some valve wrenches used in the existing production have unreasonable design, and therefore operators are required to stand on the front face of the valve to hold the valve, so that safety operation regulations are not met, and if the valve fails in the opening and closing process, the valve leaks, so that serious injury is caused to the operators. And some valves with exposed door poles are not suitable for operation.

Detailed Description

The utility model will be further described with reference to the accompanying drawings, it being understood that the description is only for the purpose of illustrating and explaining the utility model, and not for the purpose of limiting the same.

A ratchet valve wrench comprises a reversing ratchet body and a positioning clamping piece.

The reversing ratchet body comprises a handle 1, and the handle 1 is of a rod-shaped structure extending in the radial direction so as to be convenient for an operator to operate.

The end part of the handle is provided with a ring body 2, and a ratchet wheel 3 is rotatably arranged in the ring body 2. The circumference of the annular body is also provided with a reversing rod 4, and the ratchet wheel can rotate in the forward direction or in the reverse direction in different positions of the reversing rod, so that when a person uses the handle 1 to perform repeated rotation operation, the ratchet wheel 3 is ensured to synchronously perform unidirectional rotation.

The center of the ratchet wheel 3 is processed into a polygonal through hole structure to form an inner 6 angle, an inner 12 angle or an inner 18 angle.

The positioning clamping piece comprises a connecting body 5 and a chassis 6. The upper connecting body 5 can be a hexagonal prism, the lower part of the connecting body is fixedly connected with a chassis, the upper connecting body and the chassis are concentric, and a through hole is formed in the center. A plurality of clamping claws 7 are arranged and fixed at the lower side of the chassis 6. Preferably three jaws are used. The clamping jaw is a cylinder, and the end part of the clamping jaw is vertically fixed on the lower side surface of the chassis and can be fixed through threads or welding. The three clamping jaws are fixed on the end face of the lower side of the chassis at 120 degrees. The positioning clamping piece is placed into the polygonal through hole structure, and the periphery of the hexagonal prism body of the positioning clamping piece is matched and positioned with the inner wall of the through hole structure.

When the ratchet wheel is used, the three clamping claws are used for clamping spokes in the valve hand wheel, and the polygonal through holes of the ratchet wheel are sleeved into the positioning clamping piece connector. The ratchet wheel rotates unidirectionally through rotating the handle to drive the positioning clamping piece to rotate synchronously with the clamping jaw, so that the valve is opened and closed.

For some door rod exposed valves, the door rod is sleeved into the door rod through a central through hole of the positioning clamping piece when the door rod is exposed along with the valve switch.

The portable ratchet valve spanner comprises a reversing ratchet body, wherein a claw plays a role in being connected with a valve, the position is not required to be adjusted, the valve is opened or closed manually instead of being opened or closed manually, and the portable ratchet valve spanner has the advantages of being simple in structure, portable in carrying, convenient to use, low in labor cost and high in working efficiency. Various types of valves may be operated. The operator stands to the side of the valve to operate, accords with the safety operation rule, and if the valve fails in the switching process, the leakage can not cause the injury of the operator, and the valve is safe to use.

Finally, it should be noted that: the foregoing is merely illustrative of the present utility model and is not to be construed as limiting thereof, and although the present utility model has been described in detail, it will be apparent to those skilled in the art that modifications may be made to the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
