Abstract

A stress-application wrench for a circular turntable valve, comprising handle (1) and upper and lower jaws (1A1, 1B1). The handle is formed by an outer sleeve rod (1A) and an inner sleeve rod (1B) by means of sleeve joint; the inner sleeve rod is stretchable relative to the outer sleeve rod; the upper jaw is fixed on the end portion of the outer sleeve rod; the lower jaw is fixed on an end of the inner sleeve rod; the outer sleeve rod is provided with a sliding groove (1A2); the lower jaw is provided in the sliding groove; the sliding groove limits the lower jaw so that the lower jaw can only slide axially; the lower jaw moves in the sliding groove when the inner sleeve rod moves up and down. During use, the upper and lower jaws clamp a circular turntable of the valve, and the handle is pushed to rotate the turntable so as to open and close the valve.

Description

[Name of invention made by ISA in accordance with Rule 37.2] An afterburner for circular turntable valves

Technical field

The utility model relates to a valve wrench, in particular to an afterburning wrench with a circular rotary valve.

Background technique

Today's piping systems require the installation of valves that control the opening or closing of the piping. Large-sized industrial pipes usually use valves with circular turntables. Gate valves are one of the most common circular turntable valves. Gate valves are distinct gate valves and dark-rod gate valves. When it is necessary to open or close the valve, turn the circular turntable. The valve stem is rotated by the turntable to move the shutter inside the valve to open or close.

The existing problem is that large-size gate valves require a lot of force when they are opened or closed, and sometimes require several people to work together to complete, which brings certain difficulties to the operation.

Utility model content

In order to solve the above problems, the utility model provides an afterburning hand with a circular turntable valve, comprising a handle and upper and lower jaws, the handle is sleeved by an outer sleeve rod and an inner sleeve rod, and the upper jaw is fixed on the outer sleeve. The rod end portion and the lower claw are fixed to the end of the inner sleeve rod, and the outer sleeve rod is provided with a sliding groove, and the lower claw is placed in the sliding groove, and the lower jaw of the sliding groove pair is restricted to be lower The jaws can only slide axially, and the lower jaws move in the chute when the inner sleeve rod moves up and down. After the upper and lower jaws catch the circular turntable of the valve, push the handle to rotate the turntable. The handle of the valve wrench is leveraged to make it easier to operate the valve.

The technical solution proposed by the utility model is an afterburning wrench with a circular turntable valve, which is characterized in that it comprises a handle and upper and lower jaws, and the handle is sleeved by the outer sleeve rod and the inner sleeve rod. Between the outer and outer sleeves, the upper jaw is fixed to the end of the outer sleeve, and the lower jaw is fixed to the end of the inner sleeve. The outer sleeve is provided with a sliding slot, and the lower jaw is disposed on the outer sleeve. Among the chutes, the chute limits the lower jaw so that the lower jaw can only slide axially, and the lower jaw moves in the chute when the inner sleeve rod moves up and down. When in use, the upper and lower jaws are caught on the circular turntable of the valve, and the handle is pushed to rotate the turntable to open or close the valve.

The preferred solution of the present invention is that a positioning locking member is further disposed on the outer sleeve rod, and the positioning locking member is composed of a nut and a bolt, and a through hole is disposed on the outer sleeve rod and welded and fixed at a position corresponding to the through hole. The nut mounts the bolt on the nut and causes the bolt to lock the inner sleeve rod through the perforation.

The utility model has the beneficial effects that the utility model provides an afterburning hand with a circular turntable valve, comprising a handle and upper and lower claws, wherein the handle is sleeved by the outer sleeve rod and the inner sleeve rod, and the upper jaw is fixed. The end of the outer sleeve and the lower jaw are fixed to the end of the inner sleeve rod, and the outer sleeve rod is provided with a sliding groove, and the lower claw is placed in the sliding groove, and the lower jaw of the pair of sliding grooves is restricted. The lower jaw can only slide axially, and the lower jaw moves in the chute when the inner sleeve rod moves up and down. After the upper and lower jaws catch the circular turntable of the valve, push the handle to rotate the turntable. Since the force acts on the handle of the valve wrench, the handle acts as a lever, which makes it easier to operate the valve.

BRIEF DESCRIPTION OF THE DRAWINGS:

1 to 5 are schematic structural views of an embodiment of the present invention, wherein FIGS. 4 and 5 are schematic structural views during use.

6-8 are schematic structural views of two embodiments of the present invention.

In the picture,

1 handle;

1A outer jacket rod, 1A1 upper jaw, 1A2 chute, 1A31 nut, 1A32 bolt, 1A4 through the hole;

1B inner sleeve, 1B1 lower jaw;

2. Round turntable.

Detailed ways

1 to 5 are schematic structural views of an embodiment of the present invention, wherein FIGS. 4 and 5 are schematic structural views during use. The figure shows that in this example, an afterburner with a circular turntable valve is characterized in that it comprises a handle 1 and an upper claw 1A1, a lower claw 1B1, and the handle 1 is composed of an outer sleeve rod 1A and an inner sleeve rod 1B. Socketed, the outer sleeve 1A and the inner sleeve 1B can be extended and contracted, the upper claw 1A1 is fixed at the end of the outer sleeve 1A (which can be fixed by welding), and the lower claw 1B1 is fixed at the end of the inner sleeve 1B (may be The welding rod is fixed, and the sliding rod 1A2 is further disposed on the outer casing rod 1A, and the lower claw 1B1 is placed in the sliding groove 1A2. The sliding groove 1A2 limits the lower claw 1B1 so that the lower claw 1B1 can only slide axially. When the inner sleeve rod 1B moves up and down, the lower jaw 1B1 moves in the chute 1A2. 4 and 5 show that, in use, the upper claw 1A1 and the lower claw 1B1 are caught on the circular turntable 2 of the valve (the upper claw 1A1 is inside the circular turntable, and the lower claw 1B1 is outside the circular turntable) The handle 1 is pushed to rotate the turntable 2 to close the valve. Since the force acts on the handle of the valve wrench, the handle acts as a lever, which makes it easier to operate the valve.

6-8 are schematic structural views of two embodiments of the present invention. Different from the first embodiment, in this example, a positioning locking member is further disposed on the outer casing rod 1A. The positioning locking member is composed of a nut 1A31 and a bolt 1A32, and a through hole 1A4 is further disposed on the outer casing rod 1A. The fixing nut 1A31 is welded at a position corresponding to the through hole 1A4, the bolt 1A32 is attached to the nut 1A31, and the bolt 1A32 is passed through the hole 1A4 to lock the inner sleeve 1B.
