Description

Technical Field

[0001] The invention relates to a two-way water-stop gate, in particular to a two-way water-stop gate with an adjustable sealing structure. Background Art

[0002] Gates are control facilities used to close and open (waterproof) channels, and are widely used in water conservancy projects. They are an important part of Yuhong's governance projects and can be used in culverts, rainwater pools, receiving water bodies, pools, water storage rooms and flushing pits. They are suitable for municipal water supply, drainage, flood control and industrial and mining water treatment, water intakes, discharge outlets, pumping stations, channels, rivers and other places. They can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc.

[0003] The existing traditional two-way water steel gate uses a thick steel plate as the gate, and there are gate guide grooves at both ends of the gate. And matching wedge blocks are welded on the guide rail and the gate respectively. When the gate is opened and closed, the wedge blocks are pressed against each other to achieve the effect of sealing and stopping water. However, due to the wear or rust of the wedge blocks during the operation of the gate, the gate will leak and seal poorly. Once the leakage occurs after a period of operation, it cannot be repaired or adjusted to prevent leakage. And because the gate is made of a steel plate, it is often deformed by the water pressure during actual operation. This affects the use and sealing of the gate and fails to achieve the designed use effect.

[0004] And because the wedge blocks are divided into several pieces and distributed on the guide rail and the gate, there will be gaps between the wedge blocks. When the gate moves to the gap area, the rebound of the sealing strip will cause the gate to run unsteadily and produce a large impact. This greatly reduces the life of the gate, causes serious wear of the sealing strip, and even damages the gate. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to propose a two-way water-stop gate with an adjustable sealing structure, the compression amount of the sealing strip of which can be adjusted according to needs to achieve a better sealing effect, and if the pressure block is worn during later use, the sealing strip can be re-tightened by adjusting the sealing adjustment mechanism, thereby achieving a sealing and water-stopping effect.
