Manual gate valve is a common type of valve widely used in the following fields:

Industrial sector

Petrochemical industry: a pipeline system used in petroleum refining, chemical production, and other processes to transport various petroleum products, chemical raw materials, and other media, such as crude oil transportation pipelines, finished oil transportation pipelines, and inlet and outlet pipelines of chemical raw material storage tanks. It can achieve the interception and flow control of media.

Power industry: steam, water, fuel and other systems used in power stations. For example, in steam pipelines, the transportation of steam can be controlled to facilitate the start stop and maintenance of equipment; In the circulating water system, the flow of water can be adjusted to ensure the normal operation of the system.

Metallurgical industry: It is widely used in the cooling water pipelines and gas transmission pipelines of equipment such as blast furnaces and converters in steel plants. In the cooling water pipeline, the flow of cooling water can be precisely controlled through manual Gate valves to ensure the cooling effect of the equipment; In the gas transmission pipeline, gas can be cut off and flow rate adjusted to ensure production safety.

Construction field

Water supply and drainage system: used in indoor and outdoor water supply and drainage pipelines of buildings to control the flow of water. For example, the water inlet pipes and sewage discharge pipes in residential and commercial buildings, as well as the outdoor water supply and drainage networks in residential areas, can facilitate maintenance personnel to close valves, cut off water flow, and carry out pipeline maintenance and equipment replacement when needed.

Fire protection system: It is an important component of the fire water system, installed on the pipelines of fire hydrants and sprinkler systems. In the event of a fire, the valve can be quickly opened to ensure the supply of firefighting water; Normally, it is in a closed state to prevent pipeline leakage and ensure the reliability of the system.

Municipal field

Urban water supply network: used in urban water supply systems to control the distribution and interception of water flow. For example, manual gate valves can be installed at the connection between the main and branch pipes, as well as at the access points of large water consuming units, to facilitate the management and maintenance of water supply in different areas. When a pipeline failure occurs in a certain area, the corresponding valve can be closed in a timely manner to reduce the scope of water supply interruption.

Sewage treatment plant: Manual gate valves are used to control the flow direction and volume of sewage on the inlet and outlet pipelines of the sewage treatment plant, as well as the connecting pipelines between various treatment units. By adjusting the opening of the valve, sewage can be treated reasonably in various stages, ensuring the normal operation of the sewage treatment plant.

agriculture

Irrigation system: Manual gate valves can be used on the water pipelines for irrigation in farmland to control the flow and direction of irrigation water, achieving precise irrigation of farmland in different areas. Farmers can allocate water resources reasonably by operating gate valves according to the water demand of crops, improve irrigation efficiency, and save water resources.
