| titleOfInvention | Stopper |
| abstract | The utility model relates to petroleum instruments and meters, in particular to a stopper. The stopper comprises a jacket (1), a transmission shaft (2), an end cap (3) and an end cap bolt (4). The bottom and the side wall of the jacket (1) are respectively provided with a water inlet (5) and a water outlet (6) communicated with a pipe cavity of the jacket (1). A spring (7) is sleeved on the end cap bolt (4). The end cap (3) can be fixed at the lower end of the transmission shaft (2) in an up-and-down sliding mode through the end cap bolt (4). The upper section of the pipe cavity of the jacket (1) is a threaded section (8), the lower section of the pipe cavity is an end cap section (9), and the transmission shaft (2) is in threaded connection with a pipe cavity threaded section (8) of the jacket (1). The stopper is characterized in that the water outlet (6) is disposed at the end cap section (9) of the pipe cavity of the jacket (1), and the inner wall, above the water outlet (6), of the end cap section (9) of the jacket (1) is provided with a seal ring (10) matched with the outer wall of the end cap (3) in a sealed mode. The stopper has the advantages of being simple in structure, not prone to leakage and long in service life. |
