ZMQY type cast iron circular gate

Product Introduction

This product is widely used in urban water supply and drainage, metallurgy, petroleum, chemical, irrigation, electric power, textile and other industries on water treatment machine buildings to achieve flow and liquid level control, is one of the important equipment for water supply and drainage and sewage treatment.

This product is suitable for the medium is water, medium temperature ≤ 80 ℃ maximum head ≤ 10m pipe mouth, sediment, sedimentation tank, diversion canal, pump station inlet and other places.

This product is mainly composed of a gate seat, a gate, a copper sealing ring, an adjusting embarrassing block, and a lifting part. Its structure is reasonable in design, good in sealing performance, strong in corrosion resistance, long in service life, convenient in installation, and easy to open and close. The structure is square, rectangular, round, and can be opened and closed manually or electrically.

Installation Instructions

Before installation, the construction personnel must first clarify the construction drawings and be familiar with the installation dimensions and technical requirements of each part before construction. The installation must ensure that:

1. The center line of the gate coincides with the center line of the gate hole, and the maximum allowable displacement is ≤ 15mm.

2. The water stop plane of the gate shall be located on the same vertical plane and parallel to the installation plane, and the inclination angle between the vertical center line of the gate and the plumb line shall be ≤ 2.

 

Attention must be paid when installing the gate

1. When the brake rod is too long, the brake rod support shall be set to prevent the brake rod from buckling and instability during the opening and closing process, and to ensure the safe opening and closing of the gate.

2 When the gate is installed, the guide rail surface of the gate groove shall be used as the reference for correction to ensure that the gate groove is vertical and no skew is allowed. The gate rod shall be vertically raised and lowered.

3. Before the goods arrive at the delivery place, the gate must be placed horizontally to prevent deformation caused by unilateral force and affect the water stop performance.

4. The gate plate and the gate frame are precisely matched and scraped before leaving the factory. In order to ensure the water stop performance, the gate and the brake frame shall not be mixed with the products of the same specification.

5. Before water supply, the gate must be installed together with the hoist at one time, and water shall be provided after the opening and closing of the gate is light and flexible in the air test. It is strictly forbidden to pass water only when the gate is installed without the hoist.

6. The embedded parts used for the installation of the gate shall be provided by the user.

Note:

1, embedded steel plate installation welding to take intermittent welding, every 150mm section of welding!, The weld length is 50mm, the anchor anchor hook spacing on the embedded steel plate is about 400mm, and the embedded steel plate is provided by the user;

2, cast iron inlaid copper water stop structure, such as the user does not require inlaid copper or other anti-corrosion materials for the water stop, should be in accordance with the chart in the bracket size;

3. If you need to install on the pipeline and connect with the standard flange, please explain when ordering;

4. For the gate of 200~500 specification, the installation hole position does not conform to the figure. At this time, there is no installation hole at the center of the hole in the height direction, and the lower value is evenly divided by the center line;

 

5, the gate for the outer arc surface structure, can also be made into flat structure, its installation size unchanged.

Note:

1, embedded steel plate installation welding to take intermittent welding, every 150mm section of blanching seam, weld length is 50mm, embedded steel plate anchor hook spacing is about 400mm, embedded steel plate by the user's own;

2. Cast iron inlaid copper waterstop structure. If the user does not require inlaid copper or other anti-corrosion materials as the water stop, the size in brackets in the figure should be followed. 3. If it needs to be installed on the pipeline and connected with the standard flange, please explain it when ordering;

4, the gate for the outer spherical structure, can also be made into a flat structure, its installation size unchanged.
