Yonglong ammonia valve
The valve can be controlled by various transmission modes, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic, spur gear, bevel gear, etc; Under the action of pressure, temperature or other forms of sensing signals, the valve can act according to the predetermined requirements, or simply open or close without relying on the sensing signals. The valve can lift, slide, swing or rotate the opening and closing parts by relying on the drive or automatic mechanism, thus changing the size of its flow channel area to achieve its control function.
1. Body
A part that is directly connected with a pipeline (or machine equipment) to form a medium flow passage.
2. Bonnet, cover, cap, lid
The main parts connected to the valve body and forming the pressure chamber with the valve body (or through other parts, such as diaphragms, etc.).
3. Hoist (disc)
A general term for a part used to cut off or regulate the flow of medium, such as the gate in a gate valve, the disc in a throttle valve, etc.
4. Disc
The opening and closing parts of stop valve, throttle valve, check valve and other valves.
5. Body seat ring, shoulder seated, bottom seat）
It is installed on the valve body and forms a sealing pair with the hoist.
6. Sealing face
The hoist is closely fitted with the valve seat (valve body) and serves as two contact surfaces for sealing.
7. Stem
The main parts that transmit the lifting force to the lifting parts.
8. Valve stem nut
The parts that form the movement pair with the valve stem thread.
9. Stuffing box ）
The valve cover (or valve body) is filled with packing, which is used to prevent medium leakage from the valve stem.
10. Stuffing box
Fill the parts with packing to prevent the medium from leaking from the valve stem.
11. Packing gland (gland, gland flange, pne-piece glang）
The part used to compress the packing to seal.
12. Packing, packing rings
Put it into the stuffing box (or stuffing box) to prevent the packing material leaking from the double valve stems of the medium.
13. Packing seat, packing washer
The part that supports the packing and maintains the packing seal.
14. Yoke
On the bonnet or valve body, it is used to support the stem nut and parts of the transmission mechanism.
15. Impact handwheel, hammer blow handwheelimpact handwheel, hammer blow handwheel）
Handwheel structure using impact force to reduce valve operating force
