A three-way ball valve is arranged between the pump and the liquid adding outlet, the three-way ball valve comprises an inlet communicated with the pump, a first outlet communicated with the liquid adding outlet and a second outlet communicated with one end of the liquid return pipeline, and the three-way ball valve controls switching between the first outlet and the second outlet through rotation of a valve element of the three-way ball valve; the other end of the liquid return pipeline communicates with an inlet of the pump; when the valve element is switched to the second outlet, the foam liquid enters the liquid return pipeline through the three-way pipe, and internal circulation backflow is formed between the outlet and the inlet of the pump. According to the utility model, the three-way ball valve and the liquid return pipeline are additionally arranged, so that the internal circulation of the foam liquid can be realized under the condition that the output of the foam liquid needs to be stopped for a short time, the foam inlet pipeline and the foam outlet pipeline can be switched without shutdown, the liquid supply requirements of different foam fire fighting trucks are met, the workload of operators is reduced, and the fire extinguishing efficiency is improved.

The utility model relates to automobile parts, and provides a novel knuckle bearing V pusher which comprises a first connecting rod, a second connecting rod, a V-end ball head sub assembly, a first ball pin sub assembly and a second ball pin sub assembly, and the V-end ball head sub assembly comprises a mounting seat, a ball head, a metal bearing outer ring, a ball seat and an end cover. A containing cavity between the ball seat and the end cover and a containing cavity between the ball seat and the installation seat are both filled with lubricating grease, a first spiral oil channel and a second spiral oil channel are formed in the inner wall of the metal bearing outer ring, and an oil channel inlet of the first spiral oil channel is communicated with the lubricating grease in the containing cavity between the ball seat and the end cover. An oil duct inlet of the second spiral oil duct is communicated with lubricating grease in a containing cavity between the ball seat and the mounting seat, and an oil duct outlet of the first spiral oil duct and an oil duct outlet of the second spiral oil duct are both located in a bearing contact area between the metal bearing outer ring and the ball head. The problems that an existing thrust rod assembly is short in service life, and potential safety hazards exist in use of a driver are solved.

The utility model discloses an automobile torsion control arm which comprises an arm body and a shaft sleeve. A mounting cavity is formed in the shaft sleeve, a plurality of notches communicated with the mounting cavity are circumferentially distributed in the inner circumferential wall of the shaft sleeve at equal intervals, fixing pieces corresponding to the notches are fixedly arranged in the mounting cavity, the fixing pieces and the corresponding notches can form ball grooves, balls are rotationally mounted in the ball grooves, and the balls extend out of the ball grooves through the corresponding notches; through the arrangement of the notches, the fixing pieces, the balls and other components, self-lubrication can be achieved, the friction coefficient of the connecting positions of other components and the shaft sleeve is reduced, abrasion of the control arm is reduced, and the service life of the control arm is prolonged; and through the arrangement of a sliding groove, a sliding block, an adjusting groove and an adjusting piece, the control arm can effectively adapt to different use environments, and the universality of the control arm is greatly improved.
