Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like figure 1 As shown, a spray gun with one-way valve and supplementary air coordinated includes a casing 1, a base frame 2, a piston 3, a wrench 4 and a thread 5, and the base frame 2 includes a liquid inlet pipe 21, a liquid outlet channel 22 and a cylinder 23 , the piston 3 cooperates with the cylinder 23, and the connecting rod on the piston 3 cooperates with the wrench 4;

[0025] The base frame 2 also includes an air outlet port 24 communicating with the closed end of the cylinder, a liquid outlet chamber 25 arranged around the air outlet port, an annular insertion groove 26 arranged at the lower end of the liquid outlet chamber, and an annular insertion groove connected to the cylinder barrel. The connected air supply hole 27, the liquid outlet chamber 25 intersects with the liquid inlet pipe 21;

[0026] It also includes a valve body 6, a valve core 7...

Abstract

The invention provides a spray gun with a one-way valve cooperating with air supply, which comprises a shell, a base frame, a piston, a wrench and a thread and further comprises a valve body, a valve element and a sealing gasket, a valve element body of the valve element is matched with a valve element base, and a circular base plate supports a circular base plate; an air outlet connector is inserted into a cylindrical sleeve core to form a liquid outlet valve, an inserting sleeve is inserted into an annular inserting groove, a liquid outlet cavity is inserted into a connecting base, the valve element penetrates through a through hole on the thread, the circular base plate on the radial outer side of the connecting base is attached to a top plate of the thread, and the connecting base is connected with the base frame; and the valve element cavity is sleeved with the sealing gasket, the sealing gasket is attached to the circular base plate, and a center hole of the sealing gasket is communicated with an air guide hole. Due to the adoption of the structure, air supply and liquid outlet are coordinated, the sealing performance is good, and the spraying speed is high.

Description

technical field [0001] This invention relates to liquid spray guns. Background technique [0002] The current prior art, Chinese patent 202021409590.0, the invention discloses a spray gun, including a gun body, which is provided with a spray liquid channel and a liquid pressure channel connected to each other inside the gun body; a nozzle part, a pressure chamber part, and a pressure chamber part including a piston Cylinder body, pressure chamber and piston, the piston sliding seal is arranged inside the pressure chamber and realizes the suction action of the spray gun through the change of air pressure inside the pressure chamber; an air hole is opened on the piston from the outside of the piston to the middle position along the axial direction; The liquid communication part is provided with an opening and closing device inside the liquid communication part. Problems: complex structure and inconvenient assembly. Contents of the invention [0003] The object of the prese...
