玻璃钢拍门如何安装:圆柱形玻璃钢拍门安装可采用以下方式?法兰衔接?混凝土浇筑。圆柱形玻璃钢拍门中心与流道中心允许倾向不应大于3.0 mm圆柱形玻璃钢拍门四周应留有400 mm的安装空间玻璃钢拍门出口下方做成1：5斜坡。圆柱形玻璃钢拍门安装的配件螺栓或膨胀丝采用不锈钢或经过防腐处置的碳钢，密封件采用橡胶或橡胶垫片。
玻璃钢拍门安装要求：法兰衔接式玻璃钢拍门分爲翼环管法兰衔接、预埋螺栓法兰衔接及打膨胀螺丝法兰衔接三种.
玻璃钢拍门的安装运用及留意事项：
玻璃钢拍门安装可与法兰衔接，可与预埋板焊接，或二次浇注；2、浮箱拍门在运用进程中，可经过向门页密封腔体内注水或放水的方法改动门页的比重，以抵达最佳开启效果。3、拍门安装后，门座与门页间有3mm左右的间隙属正常现象，当门页承受一定的反向压力时，间隙会添加致使消逝。4、拍门在运用进程中应坚持其流道、密封圈不被石块、树枝等杂物卡堵，从而影响密封效果。5、经常清算拍门下方沉砂池内的积物，坚持拍门支耳孔、铰轴润滑良好，开启灵敏。
Characteristic of FRP clap door 1. CM type is hard water seal, economical and durable. If it is made of FRP, it can be invisibly anti-theft. 2. PM type is rubber soft water seal with good effect and impact resistance. 3. The proportion of FPM door body in water is slightly larger than that of water, and the opening head is very small (about 0.06m head after gravity offset). 4. The installation mode is flange structure, which is convenient to install. 5. Saving electricity, manpower and water disposal fees. Application scope of FRP door: It is suitable for water conservancy system, municipal sewage, urban flood control and drainage, sewage disposal plant, water works, etc. Specifications and categories of FRP clap doors: Cylindrical FRP clap doors can be designed and consumed according to the size and shape of the outlet. Cylindrical FRP clap doors can be divided into hollow floating plate type and flat plate type. Function of FRP door: nominal pressure 0.1MPa-1.0MPa. Applicable medium: water? River water? Sea water? Life? Industrial sewage temperature? < 50 C FRP door consumption process and material: using modern FRP advanced process formula, solidified in a special mould, then processed through pre-treatment process. Its main materials are unsaturated polyester resin, glass fiber cloth, glass fiber short cut silk, glass fiber yarn. This product can be divided into round and square clapping doors. According to the connection mode, it can be divided into flange connection, concrete pouring, hand paste connection and socket connection; according to the structure mode, it can be divided into hollow floating plate type, flat plate type and pump type. How to install FRP clap door: Cylindrical FRP clap door can be installed in the following ways? Flange connection? Concrete pouring. The permissible inclination between the center of the cylindrical FRP clap door and the center of the runner should not be greater than 3.0 mm. The installation space around the cylindrical FRP clap door should be 400 mm. A 1:5 slope should be made below the exit of the FRP clap door. The fittings bolts or expansion wires for cylindrical FRP flapping doors are made of stainless steel or carbon steel, and the seals are made of rubber or rubber gaskets. Installation requirements of FRP clap door: Flange-connected FRP clap door can be divided into three types: flange connection of wing ring pipe, pre-embedded bolt flange connection and flange connection of expanding screw. Installation and application of FRP clap door and matters needing attention: installation of clap door can be connected with flange, welded with pre-embedded plate, or poured twice; 2. Floating box clap door can be poured into the sealing chamber of the door page during operation. Water or drainage methods change the proportion of door pages to achieve the best opening effect. 3. After the door is installed, the gap between the door seat and the door page is about 3 mm, which is normal. When the door page is under certain reverse pressure, the gap will be added and disappear. 4. In the process of operation, the clapping door should insist that its runner and sealing ring should not be blocked by stones, branches and other debris, thus affecting the sealing effect. 5. Frequently settle the deposits in the sand sink under the clapping door, insist that the ear holes and hinge axles of the clapping door are well lubricated and open sensitively.
