A blast pipe for a spray gun assembly

Abstract

The application discloses a spray gun assembly of an explosion-proof pipe, which comprises a water inlet mechanism, a spray gun body and a water power control unit. The water power control unit comprises a water stop assembly and a movable assembly. The water stop assembly is used for controlling the opening and closing of the water inlet channel. When the control switch closes the water outlet channel, the movable assembly can control the water stop assembly to close the water inlet channel under the water pressure of the water inlet channel. When the control switch opens the water outlet channel, the water stop assembly opens the water inlet channel under the water pressure of the water supply source. When the spray gun performs a water closing action, the energy of water hammer is transmitted from the movable assembly to the water stop assembly, and a time delay is required for the action of cutting off the water path. Moreover, the water power control unit automatically cuts off the front water inlet mechanism and blocks the pressure of water hammer, so that the damage of water hammer to the spray gun assembly is prevented.

When the control switch 21 closes the water outlet channel, the movable assembly can control the water stop assembly to close the water inlet channel 11 under the action of the water pressure of the water inlet channel 11. When the control switch 21 opens the water outlet channel, the water stop assembly 30 opens the water inlet channel 11 under the action of the water pressure of the water supply source.

[0036] In this embodiment, the water stop assembly 30 comprises a water stop pad 31 for controlling the opening and closing of the water inlet channel 11; and further comprises a gland 32 fixedly installed on the water inlet mechanism 10, the gland 32 and the water stop pad 31 form a back pressure cavity 33, the water stop pad 31 is provided with a pressure relief hole 311 and a water passage hole 312 connecting the water supply source and the back pressure cavity 33, and the movable assembly is used to control the opening and closing of the pressure relief hole 311;

[0037] When the control switch 21 closes the water outlet channel, the movable assembly can close the pressure relief hole 311 under the water pressure of the water inlet channel 11, and the water stop pad 31 can close the water inlet channel 11 under the pressure of the back pressure cavity 33; when the control switch 21 opens the water outlet channel, the movable assembly opens the pressure relief hole 311, and the water stop pad 31 opens the water inlet channel 11 under the water pressure of the water supply source.

[0038] In the embodiment, an elastic member 40 is further arranged to provide elastic force to the movable assembly; when the control switch 21 opens the water outlet channel, the movable assembly resets under the action of the elastic force and then opens the pressure relief hole 311.

[0039] In other embodiments, when the control switch 21 opens the water outlet channel, the movable assembly resets under the action of its own gravity and then opens the pressure relief hole 311; or a counterweight is further arranged, and when the control switch 21 opens the water outlet channel, the movable assembly resets under the action of the gravity of the counterweight and then opens the pressure relief hole 311; or a magnetic attraction member is further arranged, and when the control switch 21 opens the water outlet channel, the movable assembly resets under the action of the magnetic force of the magnetic attraction member and then opens the pressure relief hole 311.

[0040] In the embodiment, the water inlet mechanism 10 is provided with a piston cavity 12 which is in communication with the water inlet channel 11, and the movable assembly includes a movable plug 50 which is provided with a sealing member 51 in sealing cooperation with the piston cavity 12, and the movable plug 50 can move up and down along the piston cavity 12.

[0041] In the embodiment, the movable assembly further includes a lever 60 and a switching shaft 70, the switching shaft 70 is used to control the opening and closing of the pressure relief hole 311, and the movable plug 50 controls the movement of the switching shaft 70 through the lever 60 to open and close the pressure relief hole 311.

[0042] In the embodiment, the water inlet mechanism 10 includes a water inlet pipe 13 and a water inlet connector 14, and the water inlet pipe 13 and the water inlet connector 14 are in communication and thus form the water inlet channel 11.

[0043] In the embodiment, the water stop assembly 30 is arranged in the water inlet connector 14.

[0044] In the embodiment, the water inlet pipe 13 is a hose.

[0045] In the embodiment, a water supply unit 80 is further arranged, and the water supply unit 80 includes a water inlet end 81, a first water outlet end 82 and a second water outlet end 83, and the first water outlet end 82 forms the water supply source.

[0046] In this embodiment, the water supply unit 80 further comprises a shelf 84.

[0047] The specific working process of this embodiment is as follows:

[0048] When the control switch 21 of the spray gun body 20 closes the water outlet channel, the water pressure makes the movable plug 50 move upward due to the increase of the internal pressure of the water inlet channel 11, and the lever 60 drives the switching shaft 70 to move downward due to the lever principle, thereby blocking the pressure relief hole 311. Since the water stop pad 31 is provided with a water passing hole 312, the water flow will continue to pass through the water passing hole 312 from the first water outlet end 82 (water supply source) into the back pressure cavity 33, and the pressure of the back pressure cavity 33 presses the water stop pad 31, so as to make the water stop pad 31 close the water inlet channel 11, and the sealing is more stable, thereby protecting the hose and the spray gun from being damaged due to the pressure rise of the water supply source.

[0049] When the control switch 21 of the spray gun body 20 opens the water outlet channel, the water in the water inlet channel 11 will flow to the water outlet channel of the spray gun body 20, so that the internal pressure of the water inlet channel 11 will decrease. At this time, the movable plug 50 will move downward due to the elastic force of the spring, and the lever 60 drives the switching shaft 70 to be lifted upward by the lever principle, thereby opening the pressure relief hole 311. The water flow in the back pressure cavity 33 flows out from the pressure relief hole 311, and the pressure of the back pressure cavity 33 decreases, so that the water flow of the first water outlet end 82 (water supply source) will lift up the water stop pad 31, and the water flow can enter the water inlet channel 11 and flow to the water outlet channel of the spray gun body 20.

[0050] When the spray gun performs the water closing action, the energy of the water hammer is transmitted from the movable assembly to the water stop pad 31, which needs a period of time, and there is a delay action of cutting off the water path, and the water power control unit automatically cuts off the front water inlet mechanism to block the pressure of the water hammer, thereby preventing the damage of the water hammer to the spray gun assembly.

[0051] The above description shows and describes the preferred embodiments of the present application. As mentioned before, it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the inventive concept described herein by the above teaching or related art or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the appended claims of the present application.
