Technical Scope:

1. Nominal diameter: 1/2’’~2’’

2. Nominal pressure: 1.6MPa

3. Working medium: water, non-corrosive liquid

4. Working temperature: -20 ° C ~ 150 ° C

5. Test standard: GB/T 13927-2008

Effect:

The flow resistance is small. The inner medium passage of the valve body is straight through, the medium flows in a straight line, and the flow resistance is small. 2. It is more labor-saving when opening and closing. Compared with the shut-off valve, the direction of movement of the ram is perpendicular to the direction of flow of the medium, whether it is open or closed.

Fold.

Description:

       The gate valve is one of the most common on-off valves. It is connected (opened) by means of a shutter (ie, the opening and closing member, the opening and closing member in the gate is called a gate or gate, and the gate is called a gate seat). Truncate (fully close) the media in the pipeline. It is not allowed to be used as a shut-off. In operation, the gate should be prevented from being opened slightly. The erosion of the medium flowing at high speed will accelerate the damage of the sealing surface. The double-gate slab acts as a lifting movement in the plane perpendicular to the center line of the gate seat passage, and cuts the medium in the pipeline like a gate, so it is called a gate valve.

Application:

Applicable medium: water, oil, gas, steam, etc. Application areas: mechanical equipment, chemical equipment, general parts, industrial equipment, water supply and drainage equipment, papermaking equipment, pharmaceutical equipment, general equipment, petrochemical equipment, electrical equipment, metallurgical powder equipment mining equipment, municipal, electronics industry, etc.

Working Principle:

 Relying on the hand wheel to drive the valve stem to rotate, the valve stem drives the shutter to move linearly back and forth in the valve body to open or close the valve. The hand wheel rotates clockwise, the valve is closed, the counterclockwise direction is turned, and the valve is opened.

Installation Guide:

(1) Compare the rated parameters required by the equipment with the rated parameters indicated on the product to ensure that the product meets the required requirements;

(2) The installer needs to be trained and experienced to ensure the smooth completion of the installation work;

(3) Thorough inspection is required after the installation to ensure that the installation is correct;

(4) In order to ensure that there is no accident in the installation work, the piping system should be thoroughly cleaned (using chemical reagents if necessary) before the product is installed.

Ensure that the piping system is clean, free from rust and dirt, and all filtration equipment must be removed before flushing to ensure unobstructed piping;

(5) It is recommended to install a temporary pipeline at the installation pipeline of the equipment during the initial cleaning of the system, and then install the equipment on the pipeline after the flushing work is completed;

(6) Note that the equipment should not be used in places where the medium contains more oil, mineral oil, etc., which has higher viscosity or corrosiveness;

(7) using a threaded joint that conforms to the standard to connect;
