Abstract

The utility model discloses a gate valve opening and closing tool which comprises a T-shaped main body, wherein the bottom of the T-shaped main body is connected with a clamping piece through a ratchet wheel. During operation, for buried pipeline, at first will the horizontal pole one end of T shape main part insert the opening hole of inspection shaft lid, hold the distal end of montant, utilize lever principle can open the inspection shaft lid, then turn around the instrument, insert the hand wheel of gate valve with the fastener, the horizontal pole then is as the handle this moment, because the horizontal pole has sufficient length, combines the ratchet, can easily rotate the gate valve hand wheel. Corresponding to the overhead pipeline, an operator stands on the ground, lifts the tool to enable the clamping piece to be inserted into the hand wheel of the gate valve, and then rotates the T-shaped main body to open the gate valve. Because of the ratchet wheel, the two hands do not need to be exchanged, and the tool cannot fall off. The safety is high. And because the vertical rod of the T-shaped main body is longer, even if the valve core of the gate valve pops up under the pressure of a pipeline, the operator can avoid the valve core for a long time.

Description

Gate valve opening and closing tool Technical Field The utility model relates to the technical field of valve overhaul tools, in particular to a valve opening and closing tool. Background Water supply pipelines, air supply pipelines, sewage pipelines and the like are widely arranged in various fields, such as mining areas, factories and cities. Because the pipeline is located in different positions, some pipelines are laid underground, some pipelines are laid on a bridge frame and the like, and the gate valve is immersed in water or above the water which is not touched by people, so that the opening and closing of the gate valve of the pipeline are not very convenient. When the gate valve is not in use for a long time, the opening difficulty is increased due to the influence of factors such as humidity corrosion and the like, and when the pipeline is under pressure, the gate valve has large opening resistance due to the influence of the internal pressure of the pipeline and must be opened by means of external force. The valve core of the gate valve is broken, mainly because the gate valve is in the use process, corrosion or abrasion and other phenomena occur, the effect of connection is lost after the valve core of the gate valve falls off, people can be injured by ejection when the pressure in the pipe is overlarge, and the damage of static distance to the gate valve is larger. In addition, the gate valve of the buried pipeline is generally positioned in the underground pipeline, and the shaft cover plate is heavy and inconvenient to open, and the improper opening can hurt people by squeezing hands. Disclosure of utility model The utility model aims to solve the technical problem of designing a gate valve opening and closing tool suitable for buried, overhead and under-pressure under the condition of guaranteeing the safety of operators. The utility model solves the technical problems by the following technical means: the gate valve opening and closing tool comprises a T-shaped main body, wherein the bottom of the T-shaped main body is connected with a clamping piece through a ratchet wheel. As the preferable scheme of the scheme, the clamping piece comprises a circular ring, the circular ring is coaxial with the ratchet wheel and is fixed at the bottom of the ratchet wheel, and at least two clamping claws are fixed on the circumference of the circular ring. As the preferable scheme of the scheme, the length ratio of the cross rod to the vertical rod of the T-shaped main body is 2:5-1:2. As a preferable mode of the above scheme, at least one end of the cross bar of the T-shaped main body can be inserted into the opening hole of the inspection well cover. As a preferable mode of the above scheme, the T-shaped main body is a hollow rod. The utility model has the advantages that: During operation, for buried pipeline, at first will the horizontal pole one end of T shape main part insert the opening hole of inspection shaft lid, hold the distal end of montant, utilize lever principle can open the inspection shaft lid, then turn around the instrument, insert the hand wheel of gate valve with the fastener, the horizontal pole then is as the handle this moment, because the horizontal pole has sufficient length, combines the ratchet, can easily rotate the gate valve hand wheel. Corresponding to the overhead pipeline, an operator stands on the ground, lifts the tool to enable the clamping piece to be inserted into the hand wheel of the gate valve, and then rotates the T-shaped main body to open the gate valve. Because of the ratchet wheel, the two hands do not need to be exchanged, and the tool cannot fall off. The safety is high. And because the vertical rod of the T-shaped main body is longer, even if the valve core of the gate valve pops up under the pressure of a pipeline, the operator can avoid the valve core for a long time.
