Example 1:
the present application is described in further detail below in conjunction with figures 1-6.
The embodiment of the application discloses a duckbill fire-extinguishing water gun, a gun body sleeve, wherein the top end of the gun body sleeve is provided with a gun mouth, the gun mouth is a duckbill gun mouth with a convex horizontal section, a cylindrical channel and a flat channel which are mutually communicated are formed in an inner cavity of the gun body sleeve, a baffle is fixedly connected to the inner part of the gun body sleeve at the bottom end of the gun mouth, and a through hole is formed in the baffle in a penetrating manner;
the ball valve assembly comprises a top valve seat, a bottom valve seat and a valve core sphere rotationally arranged between the top valve seat and the bottom valve seat, the top of the top valve seat is embedded with a through hole of the partition board, and a central channel of the valve core sphere is in a truncated cone shape with a wide bottom and a narrow top;
the adjusting assembly comprises a handle and a valve rod rotating shaft, the valve rod rotating shaft is rotationally connected to two sides of the gun body sleeve, the outer side end of the valve rod rotating shaft is fixedly connected with the handle, the inner side end of the valve rod rotating shaft is in embedded limit connection with the side face of the valve core sphere, and the valve rod rotating shaft is used for controlling the rotation of the valve core sphere.
Referring to fig. 1-6, the flat cavity part of the gun mouth of the gun body sleeve is in a sector shape diverging outwards, so that the range of the water curtain can be effectively expanded, and the coverage area of the water curtain is larger.
Referring to fig. 2 and 3, a sealing gasket is embedded between the top valve seat and the partition plate, the bottom valve seat is in threaded connection with the inner wall of the gun body sleeve, the sealing gasket improves the sealing performance of the joint and provides elastic stress of a contact point, and then the valve core ball body can be tightened by rotating the bottom valve seat.
Referring to fig. 1 and 3, the inner side of the handle is in threaded connection with a limit stop lever, and a limit stop is fixedly connected to a corresponding position of the outer wall of the gun body sleeve, so that the rotation state of the handle can be limited.
Referring to fig. 1-3, the bottom of the gun body sleeve is in threaded connection with a pipe connector, and a top channel of the pipe connector is in a truncated cone shape with a wide bottom and a narrow top, so that the input water flow can be initially pressurized.
Referring to fig. 2 and 3, the rotating part of the valve rod rotating shaft, which is in contact with the gun body sleeve, is embedded and fixedly connected with an O-ring, so that the tightness of the rotating part of the valve rod rotating shaft is improved, and damping is provided for the rotation of the valve rod rotating shaft.
The implementation principle of the duckbill fire-extinguishing water gun is as follows: when the water gun is used, the water gun body is connected with the water pipe through the pipeline connecting piece, the communication and the closing of the ball valve assembly inside the water gun body can be controlled through rotating the handle, and the shape and the pressure of water flow can be controlled. Please refer to fig. 4-6, in particular: when the handle is positioned at the lowest end, the pipeline connecting piece, the bottom valve seat, the valve core ball body, the top valve seat and the muzzle part form a contracted pressurizing channel, at the moment, water flow is discharged from the cylindrical channel of the muzzle part after being pressurized, and the water flow is in a common cylinder shape; correspondingly, when the handle rotates upwards to drive the valve core sphere to rotate, the central channel of the valve core sphere deflects towards the flat channel at the mouth of the gun, and at the moment, water flow impacts the inner cavity of the flat channel, so that water body diverges to two sides to form a fan-shaped water curtain; continuing to rotate upwards, the central channel of the valve core sphere is gradually blocked by the top valve seat, so that the water flow is reduced, the water pressure is also reduced, and when the central channel is completely blocked, the water flow is closed. By the adjusting mode, the free control of the water flow pressure and the jet flow shape is realized.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
