Characteristics of high-pressure cast iron gate:

High pressure cast iron gates are widely used in water conservancy and hydropower, municipal construction, water supply and drainage, aquaculture, agricultural water conservancy construction and other projects. The gate structure is reasonable, easy to install, easy to operate and flexible, and easy to manage. Strong anti-corrosion ability, can be used in fluid acids and bases with pH=6-8. Good waterproofing effect; Normal seepage rate L ≤ 0.07L/ms.

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 integral and assembled types.

Complete specifications ranging from 0.2x0.2-6.5x6.5m (with a maximum water head of 6.5m meters) and the production of rectangular cast iron gates; When the outlet is greater than or equal to 3 meters, it is a double hanging point gate.

High pressure cast iron gates are mainly suitable for forward compression waterproofing, and reverse waterproofing gates can be manufactured according to user needs.

Mechanically processed hard water stops are used in the structure, and rubber water seals can also be used for larger gate bottom seals. According to user requirements, copper or stainless steel waterproofing can be used.

High pressure cast iron gates can withstand a normal water head of 1-6 meters and can also withstand a certain amount of reverse water head. To meet user requirements, high head gates can be manufactured.

The gate should be installed as a whole and poured in the second phase. The sealing gap between the gate and the gate frame should be adjusted to below 0.3mm before the second phase pouring can be carried out. When pouring concrete into high-pressure cast iron gates, the mortar flowing into the gaps between the gate, gate frame, inclined iron, and baffle must be removed to prevent the mortar from solidifying and affecting the opening and closing of the gate. The upper and lower frames of the gate are equipped with fixing blocks to prevent the gate from slipping out during transportation, lifting, and other processes. After installation and solidification (before use), the fixing blocks of the upper gate frame and the tightening bolts of the lower frame should be removed before starting.

When opening and closing high-pressure cast iron gates, attention should be paid to the upper and lower plate limit positions of the gate to avoid damaging the gate or hoist.
