Lengthening rod gate valve features and operating environment, as well as procurement precautions, and maintenance of the detailed introduction

Extended rod gate valve is a special design of gate valve, its rod length is longer, often used in the need of deep buried, long distance or manual

operation occasions. The following is a detailed introduction to the characteristics and operating environment of the extended-rod gate valve, as well as procurement precautions and maintenance.

Features:

1. Lengthening rod design, can be operated in deep position;
2. Simple structure and easy maintenance;
3. Corrosion resistance and wear resistance;
4. Good sealing performance, reliable sealing;
5. Manual operation is convenient.

Application environment:

1. Applicable media: water, steam, gas, oil and other non-corrosive media and certain corrosive media;
2. Working temperature range: -30¡æ ~ 120¡æ;
3. Working pressure range: normal type 0.6MPa, enhanced type 1.0MPa.

Purchasing matters needing attention:

1. Select material: the valve body, valve plate, packing and sealing ring of gate valve require the selection of corrosion resistance and high strength material;
2. Valve sealing performance: select gate valves with excellent sealing performance according to the characteristics of the medium, working conditions and other requirements;
3. Manufacturer’s reputation: Gate valve is an important pipeline equipment, so it is necessary to choose the gate valve manufacturer with high reputation;
4 Valve maintenance: to choose easy maintenance, maintenance products.

Maintenance:

1. Often check the sealing performance of the valve, if there is leakage phenomenon, timely treatment;
2. Check the operation of the valve regularly to keep the lubrication of the rod;
3. If the gate is stuck, remove the gate and clean the gate valve seat and sealing surface;
4. If there are impurities in the valve body, the valve should be removed and cleaned;
5. Keep the end of gate valve dry to prevent corrosion.

In short, the extended rod gate valve has the advantages of reliable sealing and easy operation. When choosing and purchasing, attention should be paid to the material and sealing performance. The sealing performance and operation of the valve should be checked frequently during maintenance to avoid failure.
