Handwheel Forged Globe Valve Fluid Resistance Good Sealing Performance
The installation and maintenance of globe valve should pay attention to the following matters:
1. Stop valves operated by handwheels and handles can be installed at any position in the pipeline.
2. Handwheel, handle and rotating mechanism are not allowed for lifting.
3. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
4. Regularly check the seal.
Features of globe valve:
1. The structure of globe valve is simpler than that of gate valve, and it is more convenient to manufacture and maintain.
2. The sealing surface is not easy to wear and abrasions, and has good sealing performance. There is no relative sliding between the valve disc and the valve body sealing surface during opening and closing, so the wear and abrasion are not serious, the sealing performance is good, and the service life is long.
3. When opening and closing, the valve stroke is small, so the height of the stop valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.
4. The opening and closing moment is large, the opening and closing is more laborious, and the opening and closing time is the principal.
5. The fluid resistance is large, because the medium passage in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
6. Media flow direction: When the nominal pressure PN ≤ 16MPa, the general flow is used, and the medium flows upward from the valve disc; when the nominal pressure PN ≥ 20MPa, the reverse flow is generally used, the medium flows downward from the valve disc. . In use, the medium of the shut-off valve can only flow in one direction, and the flow direction cannot be changed.
1. If customers have special requirements for products, they must provide the following instructions in the order contract:
a. Structure length
b. Connection Type;
c. Nominal diameter
d. Product use medium and temperature and pressure range;
e. Testing, inspection standards and other requirements.
2. The factory can configure various driving devices according to customer specific requirements.
3. If the determined valve type and model are provided by the customer, the customer should correctly explain the meaning and requirements of its model, and sign the contract on the condition that the supply and demand sides understand and agree.
4. For futures and ordering customers, please call the letter to tell the valve model, specifications, quantity, delivery time and place in detail. And advance payment of 30% of the total contract amount, the supplier is ready for production.
