Paddle valve

Abstract

The invention discloses a GLP03 type paddle valve comprising a floodgate frame and a flashboard; a seal valve buckle is fixed on the floodgate frame; the seal valve buckle is in a U-shaped structure which is arranged between the flashboard and an installation wall surface; the opening of the U-shaped structure is towards the flashboard; a double lip-shaped rubber sealing strip is installed in the sealing floodgate frame; and the lip-shaped part of the double lip-shaped rubber sealing strip is contacted with the flashboard, which plays a seal function. Interference close fit is formed between the lip-shaped part of the double lip-shaped rubber sealing strip and the flashboard, thus preventing fluid medium at the internal direction and the external direction of the paddle valve from passing through, and realizing bidirectional water stopping effect. Foamed rubber sealing strips are arranged between the floodgate frame and the installation wall surface and between the sealing valve frame and the installation surface, which play the function of water stop. The paddle valve of the invention has simple and lightweight design structure, high strength, convenient installation and maintenance and good bidirectional water stopping effect; compression resisting safety factor is larger than 6; and the highest adaptive water pressure can reach 10 water heads.

Description

Technical field: [0001] The present invention relates to a valve, more specifically it relates to a gate valve. Background technique: [0002] The gate valve commonly used now usually includes a gate frame and a gate plate, and guide devices are arranged in the two vertical gate frames, and the gate plate moves up and down along the guide device to realize the closing and opening of the gate. During use, since the gate and the guide device are often in a state of friction and are prone to wear and tear, the positioning of the guide device to the gate is not accurate, resulting in a decrease in the degree of sealing between the gate and the gate frame, and leakage occurs. In severe cases, it is necessary to Replacement of valves results in increased production costs. In addition, because the concrete wall surface is not very smooth during the construction process, the sealing effect between the gate frame and the concrete wall surface is often not good, and leakage will also...

Problems solved by technology

During use, since the gate and the guide device are often in a state of friction and are prone to wear and tear, the positioning of the guide device to the gate is not accurate, resulting in a decrease in the degree of sealing between the gate and the gate frame, and leakage occurs. In severe cases, it is necessary to Replacement of valves, resulting in increased production costs

In addition, because the concrete wall surface is not very smooth during the construction process, the sealing effect between the gate frame and the concrete wall surface is often not good, and leakage will also occur. In short, the two-way water stop of the gate valve of the existing structure The effect is not very ideal
