LT6529B - A labor-saving handle for round valve handle - Google Patents

Abstract

It usually takes a lot of effort to open or close the existing industrial piping valves manually due to their large size, with the nominal diameter often exceeding several hundred millimeters. In order to solve the above problems, a labor-saving handle for round valve handle provided in the present invention, which is characterized in the handle body and the jack catch. The said handle body is sleeve-connected by the inner sleeve rod and the outer@sleeve rod, with the inner sleeve sheathed inside the outer sleeve rod and stretchable between the sleeve rods. The said jack catch includes the first and the second jack catch. The first jack catch is set at the upper end part of the inner sleeve rod, and the second jack catch is set at the upper end part of the outer sleeve rod. The first jack catch has V-shaped structure, and the second jack catch has V-shaped structure. A bayonet is formed between the first@and the second jack catch. The width of the bayonet is changed when the inner and the outer sleeve rod are stretched. The said bayonet is fixed to the round handle in use, pushing the handle to open or close the valve. And since the force is acting on the handle body in operation, the handle body acts as a lever, making the operation more labor-saving.

Description

TECHNICAL FIELD

The present invention relates to the field of pipe closure valve, valve, in particular, a tool for facilitating the opening and closing of the valve, with a round handle.

TECHNICAL LEVEL

In piping systems, valves, valves that close or open the inner cavity of a pipe for the flow of gas or liquid are used to control the parameters of gas or liquid flow through pipes. The manual valve is often provided with a round, circular handle. Turning the handle rotates the main valve rod to control opening and closing of the valve. The valve handle is usually round, circular or long rod shaped. The round, circular handle is comfortable, easy to use and is often used in large-sized valves. It often takes a lot of effort to open and close industrial pipe valves by hand, due to their large size, often exceeding several hundred millimeters in diameter. Especially when the valve is closed, it takes a lot of physical effort to open the valve because the main valve rod is pressurized and sometimes requires several people.

Document CN 205466007 (published August 17, 2016) discloses a tool which, in comparison with the present invention, is a sophisticated construction suitable for unscrewing valve handles specially adapted for use with the provided tool only, not suitable for use with other valve handles. With this description, the following is a new tool, the handle has no listed drawbacks.

THE SUBSTANCE OF THE INVENTION

To solve the above problems, the present invention provides an invention: a tool for facilitating work, a handle for rotating a circular valve handle. The handle for ease of use has a handle body and plugs. Said handle body comprises an inner rod and an outer rod connected by a sleeve, and the inner rod is enclosed by an outer rod and can be stretched relative to one another. Said plugs include first plugs and second plugs. The first plugs are located at the top end of the inner rod and the second plugs are located at the top end of the outer rod. The construction of the first plugs resembles a U shape, the second plugs also resemble a U shape. A gap is formed between the first and second plugs.

The gap is resized when the inner and outer rods are stretched relative to each other. The aforementioned handle gap is provided with a circular valve handle, the gap being reduced to pinch the valve handle to open or close the valve. The elongated handle housing (inner and outer rods) acts as a longer force arm for greater torque and thus requires less physical effort to rotate difficult to turn valve handles.

Said handle body comprises an inner rod and an outer rod connected by a sleeve, and the inner rod is enclosed by an outer rod and can be stretched relative to one another. Said plugs include first plugs and second plugs. The first plugs are located at the top end of the inner rod and the second plugs are located at the top end of the outer rod. The first plugs resemble a U shape, the second plugs also resemble a U shape. A gap is formed between the first and second plugs. The gap is resized when the inner and outer rods are stretched relative to each other. A circular valve handle is inserted into the aforementioned handle gap, which is reduced to pinch the valve handle to open or close the valve.

Another embodiment of the present invention: said U-plugs of the first plugs are placed on a circular valve handle spindle used.

Another embodiment of the invention: the lower end of said outer rod has a handle, a handle, a handle for a more convenient grip. The said rod is mounted on the joint of the outer rod and the inner rod, at the lower part of the inner rod. When using the tool, the clearance between the plugs is adjusted to the circular handle of the valve and locked. The rod is mounted on the inner and outer rods, locked, and adapted to the work, i.e. to rotate the round valve handle.

Another embodiment of the invention is: the outer tube has a locking ring which defines the position of the rod engaging on the outer tube, and when the rod is mounted on the outer tube, the rod is fixed to the locking ring.

An advantage of the present invention is that the inventive tool facilitates unscrewing and unscrewing the round valve handle. The handle for ease of use has a handle body and plugs. Said handle body comprises an inner rod and an outer rod connected by a sleeve, and the inner rod is enclosed by an outer rod and can be stretched relative to one another. Said plugs include first plugs and second plugs. The first plugs are located at the top end of the inner rod and the second plugs are located at the top end of the outer rod. The first plugs resemble a U shape, the second plugs also resemble a U shape. A gap is formed between the first and second plugs. The gap is resized when the inner and outer rods are stretched relative to each other. A circular valve handle is inserted into the aforementioned handle gap, which is reduced to pinch the valve handle to open or close the valve. The description provides a tool, the handle has a simple design and is easy to manufacture. The elongated handle housing (inner and outer rods) acts as a longer force arm for greater torque and thus requires less physical effort to rotate difficult to turn valve handles.
