Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1 to 9.

Example 1

The utility model provides a pair of embodiment: as shown in figure 1, the novel double-layer heavy hammer air locking valve comprises a valve body 6, a chute 7 is arranged at the top end of the valve body 6, a valve plate 5 is arranged at the bottom of the chute 7, one end of the valve plate 5 is connected with a shaft 1, rocker arms 2 are arranged on the front side and the rear side of the valve body 6, and the rocker arms 2 are connected with the shaft 1.

Chute 7 includes location border frame, and location border frame and valve body 6's top flange joint, the bottom rigid coupling of location border frame have the barrel, and the barrel is located the inner chamber upper end of valve body 6, is convenient for fixed the installation of chute 7 on valve body 6.

The top of the valve plate 5 is provided with an elastic sealing gasket, so that the sealing performance of the valve plate 5 when the bottom of the chute 7 is contacted with the valve plate is improved.

The rocker arm 2 comprises a limiting sleeve and a handle bar, the limiting sleeve is fixedly connected to one end of the handle bar, protective grains are arranged on the outer wall of the handle bar, friction between hands and the handle bar is increased, and the rocker arm 2 is convenient to use.

The limiting sleeve is provided with a four-edge sleeve hole, and the four corners of the inner cavity of the four-edge sleeve hole are provided with round corner faces, so that the limiting sleeve can limit the position of the shaft 1 after being sleeved on the shaft 1, and the rocker arm 2 and the shaft 1 can be used in a linkage manner conveniently.
