    When the flap door leaks, what should we do? According to the technical requirements of Xiaobian, we should first check whether the flap cover is too light and the pressure is not enough to cause leakage. The solution is to add some weight on the valve cover, increase the pressure, and solve the problem of FRP valve production process and material leakage: adopt modern FRP advanced process formula, mature in special mold, and then after post-treatment, processing. Its main raw materials are unsaturated polyester resin, glass fiber cloth, glass fiber chopped yarn, glass fiber yarn, etc. This product can be divided into round door and square door. According to the connection form, it can be divided into flange connection, concrete pouring, hand paste butt joint and sleeve; according to the structure form, it can be divided into hollow floating plate, flat plate and pump.

    For many years, the steel racket gate has been seriously affected by counter current irrigation at the outlet. The racket gate is often damaged and falls off, which affects the water quality and sealing performance of the outlet pump. A large number of parts have been replaced and repaired for many times, but due to strength, wear, corrosion and many other factors, process modification can not be carried out. The continuous and stable operation of the plant has a great influence on the successful completion of the production tasks of the plant. At the same time, the daily maintenance and rescue of the damaged flap also consumes a lot of manpower, material resources and financial resources. In the past, the racket gate of pumping station was easy to be damaged under the impact of reverse flow. Due to the poor strength and brittleness of cast iron, it is difficult to bear repeated heavy load impact. In the long run, the racket door of the pumping station will be broken and broken. In order to reduce the outlet water level, it is necessary to increase the number of pump openings in the process of maintenance and replacement. The crew jumped into the water outlet to rescue the broken pieces of the door to prevent the pieces from being washed into the water outlet pump blade. The fishing process is time-consuming and laborious, and there are some unsafe factors in underwater operation. It should be arranged according to the following contents: the number of flange and the size of the product.

    To ensure that the flap door is watertight, it is necessary to clean up the cement, debris and oil stains on the frame beam, apply waterproof sealant (or rubber pad), install the composite baffle door on the anchor bolt on the frame beam, tighten the nuts symmetrically and evenly repeatedly, and check the composite baffle cover and the composite baffle door while screwing. The sealing surface of the valve seat shall be in good condition. All bolts shall be tightened. The valve disc and cover shall be able to open and close freely without obstruction. The sealing surface shall have no clearance.

    Ҫ¼㣺We also need to do the following:

    1. Anchor bolts, nuts and washers shall be galvanized or stainless steel parts, and shall be applied with anti-corrosion coating twice after installation. Each anchor bolt shall be equipped with a nut, a flat pad and a spring pad.

    2. The distribution of anchor bolts should be based on the vertical, and the length of foundation plane should be extended.

    4. The flap door can also be installed and fixed with planting bolts and expansion bolts. On the surface of the flat concrete frame, the drilling position is drawn according to the position of the flange bolt hole of the gate, and the drill with a diameter of 2mm is used according to the specifications of the planting bolt and the expansion bolt. After the bolt is cured, the composite baffle door can be installed.

    5. When installing the concrete pouring racket door, fix the steel racket door with the bracket, and make the center line slightly upward 1-2 degrees. The hinge axis of the racket door should be placed to a certain extent. When pouring, cement and gravel shall not enter the racket door cover and hinge shaft.
