Abstract
The utility model discloses a deflation valve easy to use. The deflation valve comprises a valve body and a valve rod which is disposed in the valve body and matched with the valve body and protrudes out of the valve body, and the valve rod is in threaded connection with a cap spinner. For improvement, the valve body is provided with a stepped protruding edge, a rotatable valve sleeve is sleeved on the outer side of the valve body in a sealed manner, a compressing ring is connected to the valve body in a clamping manner, the valve sleeve is limited between the stepped protruding edge and the compressing ring, a tensioning spring is disposed between the compressing ring and the cap spinner, and the tensioning spring is sleeved on the outside of the valve rod. The side of the valve body is provided with a deflation hole, deflation is realized through an exhaust pipe disposed on the valve sleeve which is disposed on the outer side of the valve body through sealed and sleeved connection, the valve sleeve is limited through the stepped protruding edge and the compressing ring, the compressing ring is connected with the valve body in the clamping manner, and the clamping connection between the compressing ring and the valve body is fixed through the tensioning spring disposed between the compressing ring and the cap spinner, so that the parts of the valve body are easy to detach and the valve sleeve can be connected to the valve body in a freely rotatable manner. The valve sleeve can rotate freely, and the deflation valve is easy to disassemble and use.
