The copper-inlaid cast iron gate is wedged tightly by the wedge device to achieve sealing. The sealing material is copper alloy or rubber and is ground after precision machining, so it has good sealing performance.
Using embedded steel plates or embedded bolts for installation, installation, debugging, use and maintenance, and long service life.
Complete varieties and specifications and wide adaptability.
The copper-inlaid cast iron gate is used in conjunction with the hoist. The gate is the working part. The hoist is the executive part for opening and closing the gate. The hoist is driven by a human motor or a pneumatic hydraulic mechanism, and the gears, worms, and other gears of the transmission device are driven and driven. The rotation of the nut or screw causes the gate shaft to move vertically up and down to open or close the gate to achieve the purpose of shutting off the water or adjusting the water level.

The gate is mainly composed of three parts:
①Main activity The part used to close or open the opening is called a gate or door leaf
②The embedded part
③Opening and closing equipment.
The gate is a strong fence located on the gate channel that can be lowered to block the door when necessary. The gate of the castle is a gatehouse with an internal space and is a strong stronghold for the defense of the castle. One can reach the gatehouse through a tunnel from the gate's passage. There will be one or more levels of gates in the middle or at both ends of the tunnel. The rolling mechanical action can lift or lower the gate above the gatehouse for solid protection. The gate itself was usually a heavy wooden or iron barricade, and the defenders shot or prodded on either side of the gate.

According to the structure, they can be divided into:
One-way rising rod type square and round gate (model: one-way concealed rod type Square and round gate (model: two-way lifting rod type square and round gate (model: hoist) is divided into: handwheel type (model:) hand-cranked type (model:) flashlight dual-use type (model:) and dual-purpose hoist Suspension point type (model: )
According to the installation method, it can be divided into:
) Wall type: suitable for the installation of one-way gates such as round gates and square gates
Civil engineering reserved hole ratio gates Large diameter.
b) Wall-mounted type: suitable for the installation of one-way and two-way gates of all specifications. Civil engineering reservations are the same as the gate diameter
) Flange type: suitable for all When installing one-way and two-way circular gates, the flange seal of the wall-penetrating pipe
The cover size should be consistent with the flange sealing surface size of the gate. The wall-penetrating pipe should protrude from the wall to ensure installation. When the wall-penetrating pipe is a steel pipe When installing, a steel flange needs to be prepared with the gate flange. After the two flanges are assembled, the flange standard is: B/.
)Flat-bottom type: It is suitable for occasions where the amount of sediment is large, especially where there are lumps that are easy to cause blockage in front of the gate.
) Bottom-opening type: Suitable for situations where there is no space when opening upward. Only suitable for one-way gate installation.
)Self-supporting type: Suitable for occasions where the hoist platform cannot be installed on the upper part of the channel installation.
Overview of the two-way water-stop cast iron gate:
The two-way water-stop cast iron gate consists of a bottom frame and a cover frame door leaf. Both sides of the door leaf friction surface are precision machined. The angle of the gate and the gate frame is tapered. , the gap becomes smaller as the gate goes downwards, thus forming a two-way water stop effect. The door frame and gate plate are made of high-quality gray cast iron or ductile iron. The guide rails are symmetrically arranged and connected to the ends of the door frame with stainless steel bolt positioning pins (for gates with medium and small diameters, the guide rails can be cast into one piece with the door frame) , the length of the guide rail is generally /~/ of the full opening height of the gate, so the overall structural strength is high, rigidity is high, wear resistance and corrosion resistance are good, and the pressure bearing capacity is large.

: > ★< /r/>When installing the two-way water-stop cast iron gate, it must be installed as a whole. The second phase of pouring can only be carried out after the water sealing gap between the plate and the gate frame is adjusted to the following value. 
★When pouring concrete, the mortar flowing into the gap between the gate gate frame and the inclined iron baffle must be removed to prevent the mortar from affecting the opening and closing of the gate after solidification. 
★The upper and lower frames of the gate are equipped with fixed blocks to prevent the gate from sliding out during transportation and hoisting. After installation and solidification (before use), the fixed blocks of the upper gate frame and the tightening bolts of the lower frame should be removed first. , to start. 
★When opening and closing the gate, you should pay attention to the upper and lower limit positions of the gate to avoid damaging the gate or hoist
