1. Body
It is directly connected with the pipeline (or machine equipment) and forms the part of the medium flow channel.
2. Bonnet (bonnet, cover, cap, lid)
The main parts that are connected with the valve body and form the pressure chamber with the valve body (or through other parts, such as diaphragms, etc.).
3. Opening and closing parts (disc)
A general term for a part used to cut off or regulate the flow of a medium, such as a gate in a gate valve, a disc in a throttle valve, etc.
4. Disc (disc)
Opening and closing parts in valves such as globe valves, throttle valves, and check valves.
5. Valve seat (bodyseat ring, shoulder seated, bottom seat)
It is installed on the valve body and forms a sealing pair with the opening and closing parts.
6. Sealing face
The two contact surfaces of the opening and closing parts and the valve seat (valve body) are tightly fitted and act as a seal.
7. Stem (stem, apindle)
The main part that transmits the opening and closing force to the opening and closing parts.
8. Stem nut (yoke bushing, yoke nut)
A part that forms a kinematic pair with the valve stem thread.
9. Stuffing box
On the valve cover (or valve body), it is filled with packing, which is a structure used to prevent the medium from leaking from the valve stem.
10. Stuffing box
Parts that are filled with packing to prevent medium from leaking from the valve stem.
11. Packing gland (gland, gland flange, pne-piece gland)
Parts used to compress packing to achieve sealing.
12. Packing (packing, packing rings)
Put it into the stuffing box (or stuffing box) to prevent the leakage of the medium double valve stem.
13. Packing seat, packing washer
Parts that support the packing and keep the packing sealed.
14. Bracket (yoke)
On the bonnet or valve body, it is used to support the stem nut and the parts of the transmission mechanism.
15. Impact handwheel
(impact handwheel, hammer blow handwheelImpact handwheel, hammer blow handwheel)
