The described back-moving spring other end offsets with the inlet suction port being loaded on handle, and back-moving spring is compressive state.
Described gas passage is two.
On the thimble of described valve body, be set with O type circle.
Between described air outlet adapter and handle, be provided with sealing ring.
On described handle, have handle mounting groove, handle is arranged in handle mounting groove by pin.
Described air outlet adapter is provided with gas outlet, and gas outlet center is aimed at the remote edge 2-3cm place of scoop.
Described thimble outer wall and valve body pilot hole are matched in clearance.
Handle, spring and valve body are installed on handle, and its inside is provided with two isometrical Compressed Gas passages; " O " type that is provided with on the thimble of spool seals, and the rear mounting spring of valve body is equipped with packing ring between the inlet end sleeve contact-making surface of valve body and handle; Handle and handle are connected and fixed by pin; Air outlet adapter one end is connected with handle, and the other end is flat and scoop is bolted, and between air outlet adapter and handle, is provided with sealing ring.It between inlet suction port and handle, is immovable fitting.Pin and handle are interference fit, and pin and handle are matched in clearance.It between connector and handle, is immovable fitting.Spring is all the time in compressive state, and after installing, its maximum compressibility that can reach is greater than thimble stroke.
The utlity model has the cleaning of shovel sand and two functions of Air blowing cleaning, also simplified operating procedure, by two Process step combination to processing steps, simplified operating procedure, improved efficiency simultaneously.The utility model compared with prior art has easy to operate, simple in structure, easy to manufacture, cost is low, be easy to the features such as production.Solved workman needs the constantly drawback of replacing operation tool in the time that template is cleared up, and has realized minimizing operation tool quantity, has facilitated on-the-spot production management; Simplify processing step, significantly reduced the time waste in scale removal process, improved production efficiency.
