The purpose and characteristics of portable cast iron gates:
☆ Mainly used for water conservancy and hydropower, municipal construction, water supply and drainage, agricultural water conservancy construction, sewage treatment and other projects.
☆ Strong anti-corrosion ability, can be used in fluid acids and bases with pH=6-8.
The gate structure is reasonable, easy to install, simple and flexible to operate, and easy to manage.
☆ Mainly suitable for forward compression waterproofing, with a normal water head of 1-8m. High head gates can be manufactured according to user needs, with a maximum forward design head of up to 50m and a reverse design head of up to 20m.
When the gate is closed, it is equipped with locking and stopping devices. The structure adopts machined surface hard water stop, which has good water stop effect and extremely strong sealing. The normal water leakage rate is L ≤ 1L/h · m.
☆ Complete specifications ranging from 0.2 × 0.2-6 × 6 meters. According to the structural form of the gate, it can be divided into PZ type flat plate gate and PGZ type flat arch gate, which can also be divided into two forms: integral and assembled.
The door body and frame are made of gray cast iron (or ductile iron), which has undergone internal stress relief and is free of deformation. According to user requirements, the water stop surface can be precision machined and manufactured using corrosion-resistant materials such as copper or stainless steel inlay. Rubber sealing can also be used for water sealing.
