[0002] Air sweeping air nozzle, also known as arch breaking air nozzle, flow aid, blockage remover and fluidizer, is widely used in cement plants, concrete, feed processing plants and other important storage and transportation of bulk materials, and plays a very important role in industrial production. In various storage bins, due to moisture, backlog and other reasons, different types of arching and blocking phenomena can occur. Air cannon is a special device for preventing and eliminating various types of material arching, blocking, wall sticking and retention in material bins, hoppers and pipeline branches.

[0003] The existing fluidization nozzle is too complicated to connect with the fixed pipe, which affects the installation and later maintenance of the nozzle. The shape of the nozzle also directly affects the effect of high-pressure airflow after being sprayed. Patent No. CN205132152U discloses an air cannon nozzle, which includes a front nozzle, a rear interface and a side wall. The side wall, the front nozzle and the rear interface together form a space that is sealed on the side and transparent at both ends. The cross-sectional area of the front nozzle is larger than that of the rear interface, which improves the use efficiency. However, the nozzle forms a horn shape, and the jet flow force is small, which cannot have a good blockage removal effect. In addition, the material flows back to the pipeline, polluting and damaging other components. UTILITY MODEL CONTENTS

A spring is inserted into the spring guide rail away from the valve rod. A flow divider is arranged on the side of the spring guide rail close to the valve rod. Multiple flow divider grooves are arranged on the flow divider to divide the flow.

[0006] Preferably, the spring is provided with a spring compression washer away from the side of the spring guide rail.

[0007] Preferably, the spring compression washer is provided with an elastic stop nut away from the side of the spring guide rail.

[0008] Preferably, the elastic stop nut is provided with a locking nut on the side away from the spring compression washer.

[0009] Preferably, the valve body is provided with a first external thread on one side, and the first external thread is used to connect a shaft coupling.

[0010] Preferably, the valve body is provided with a flange on the outside, and the flange is used to install and fix the shaft coupling.

[0011] Preferably, the head plane is a second arc-shaped plane, so as to increase the force receiving area.

[0012] Preferably, the elastic stop nut and the locking nut are further provided with a first gasket and a second gasket, and the first gasket and the second gasket are connected through a clutch ratchet.

[0013] Preferably, the first gasket is provided with a plurality of grooves on the side close to the locking nut and along the circumference.

[0014] Preferably, the valve body is provided with a second external thread on the side away from the valve rod, and the second external thread is used to connect a mating part.

[0016] 1. In use, the high-pressure airflow enters the valve body and is sprayed out at the valve rod, is distributed through the distribution grooves on the distribution piece, and is uniformly sprayed out in the gap between the valve body and the valve rod.
