Installation and use of gate water stop rubber
The gate is a common water conservancy project in the water conservancy project. If the gate is not strictly controlled in the water conservancy project, the engineering quality of the hoist and other machinery will be reduced, which will have a certain impact on the future management work. Therefore, attention should be paid to the quality of the sluice construction project.
The gate leakage is mainly due to the gap between the water stop rubber and the water stop slide due to the fact that the water stop rubber and the water stop surface are not on the same plane; Water leaks from the bolt hole of the water stop rubber, the joint between the bottom water stop rubber and the side water stop rubber, or the joint of the water stop rubber, so that the water stop rubber and the door leaf are smoothly and straightly affixed, or there is no deviation or gap between the water stop rubber and the water stop seat plate or the slide way; The screw holes on the reserved screw hole water stop pressure plate of the gate leaf shall be consistent, and then the water stop rubber shall be drilled or punched; The gate sealing rubber shall be customized as far as possible to reduce rubber joints to prevent such situations.
Gate water stop rubber
Introduction to gate water stop rubber:
The material of gate water stop rubber is divided into: the water stop rubber is made of natural rubber (or synthetic rubber) through the rubber mixing equipment (open type rubber mixing machine or internal mixer), and then mixed with more than ten kinds of raw materials, such as special antioxidant, vulcanizing accelerator, vulcanizing aid, reinforcing agent, plasticizer, etc., to produce semi-finished mixed rubber, which is then placed in a mold with a certain cavity, and then vulcanized by a vulcanizing press under high temperature The water stop element, which is made under high pressure and meets the comprehensive requirements for water stop of hydraulic steel gate, is commonly known as gate water seal or water stop rubber.
Properties of gate sealing rubber: Therefore, it is very important to select suitable water stop rubber according to the nature and operating conditions of each type of gate. According to the material of water stop rubber, the rubber water stop rubber is a semi finished compound made of natural rubber (or synthetic rubber), which is refined in stages by rubber mixing equipment (open rubber mixing machine or internal mixer), and then mixed with more than ten kinds of materials, such as special antioxidant, vulcanizing accelerator, vulcanizing aid, reinforcing agent, plasticizer, etc,
The water stop element, commonly known as ordinary water stop rubber, is made by placing it in a mold with a certain cavity and vulcanizing press under high temperature and high pressure, which meets the comprehensive requirements for water stop of hydraulic steel gate. The reinforced polytetrafluoroethylene film with low friction and high abrasion resistance is compounded on the working face of water stop rubber and water stop, which is called rubber plastic composite water seal; The high-strength nylon canvas is placed in the water stop rubber to achieve reinforcement, low friction
The water seal that doubles the abrasion resistance is called high strength nylon canvas water seal; The water seal with both high-strength nylon canvas and polytetrafluoroethylene film (or polytetrafluoroethylene coating) is called the rubber plastic composite water stop rubber with high-strength nylon canvas; The water stop rubber made from polyfluoroethylene and polyethylene is called pure plastic water stop rubber
