Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described below with reference to the drawings of embodiments of the present invention.
In the embodiment of the method, the first step,
referring to fig. 1, an apparatus for preventing venturi tube extrusion under high pressure includes a water outlet pipe 1, a venturi tube 2 and a liquid suction assembly 3.
Wherein, the side of the water outlet pipe 1 is provided with a side hole 4. Side port 4 has disposed therein a wicking assembly 3 and a stopper 8. A fourth O-shaped sealing ring 11 is also arranged between the water outlet pipe side hole 4 and the liquid suction component 3.
The liquid suction component 3 is provided with a body 31, a spring 32 and a marble 33, wherein a through hole 34 extending from top to bottom is arranged at the center of the body 31, the marble 33 is arranged in the through hole 34, one end of the spring 32 is abutted against the marble 33, and the other end of the spring is abutted against the stop block 8. A step is provided in the through hole 34, and a third O-ring 35 is further provided between the ball 33 and the inner wall of the body 31.
The venturi tube 2 is arranged in the inner cavity of the water outlet pipe 1, a first O-shaped sealing ring 5 and a second O-shaped sealing ring 6 are arranged between the venturi tube 2 and the inner wall of the water outlet pipe 1, and a groove 7 is arranged on the outer circumferential wall of the venturi tube 2.
The venturi tube 2 is provided with a liquid suction hole 9, and the liquid suction component is arranged right opposite to the direction of the liquid suction hole 9.
The lower end of the stopper 8 is seated in a recess 7 of the venturi tube to limit the movement of the venturi tube 2, and a central hole 10 is provided in the center of the stopper 8 in alignment with the center of the pipetting assembly 2.
According to the figure, we can see that the venturi tube 2 is installed in the water outlet pipe 1, and the blocking plug 8 is installed in the position of the liquid suction hole, in the figure we can see that the blocking plug 8 is clamped on the groove 7 of the venturi tube 2, and finally, the displacement of the blocking plug 8 is limited by pressing the blocking plug 8 by the liquid suction assembly 2, so as to prevent the venturi tube 2 from being ejected in the process of high pressure. The utility model discloses a prevent venturi and spray through keeping off stifled, and because what venturi generally adopted is the plastics material preparation, so long-time work probably can make and keep off the position of stifled contact and great wearing and tearing appear, can select some better materials of wearability to make when consequently we make venturi to thickening contact site's thickness prolongs its live time.
The above description and the drawings only show the preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can appreciate that the technical solutions and the inventive concepts of the present invention can be equally replaced or changed within the technical scope of the present invention.
