Description
Technical Field
The utility model relates to a high pressure cleaner, especially an automatic exhaust valve.
Background
The high-pressure cleaning machine is a device which drives a high-pressure pump to generate high-pressure water to wash the surface of an object through a power device. The high-pressure pump is provided with an exhaust valve which is used for exhausting air in the pipeline. When the high-pressure cleaning machine is used, the exhaust valve is opened manually, power is started again, after water is discharged from the water outlet, the exhaust valve is closed manually, and then the high-pressure pump enters a normal working state. As can be seen from the above, when using the high pressure cleaner, the exhaust valve needs to be opened and closed manually first, thus increasing the operation trouble of the operator.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an automatic exhaust valve is provided, this automatic exhaust valve can reduce operation personnel's vexation numb when using high pressure cleaner.
In order to solve the technical problem, the utility model relates to an automatic exhaust valve, which comprises a left valve body, a right valve body, a steel ball, a spring, an O-shaped ring and a gasket, wherein the center of the left valve body is sequentially provided with three step holes, the inner diameter of the three step holes is coaxially communicated from small to large, the left hole is a vent hole, the middle hole is a spring hole, the right hole is a steel ball hole, the outer surface of the right end part of the left valve body is provided with threads, the spring is arranged in the spring hole, the O-shaped ring is arranged at the left side of the spring hole, the steel ball is positioned in the steel ball hole, a gap is arranged between the steel ball and the steel ball hole, the inner right part of the right valve body is provided with an air inlet hole, the inner left part of the right valve body is provided with an assembly hole, the air inlet hole is communicated with the assembly hole, the surface of the right end part of the right valve body is provided with threads, the right end part of the left valve body is screwed in the assembly of the right valve body, and the steel ball can axially move in the steel ball hole along the steel ball hole.
And an assembly flange is arranged on the outer surface of the left end part of the left valve body.
And the outer surface of the left end part of the right valve body is provided with a mounting flange.
The O-shaped ring is a rubber O-shaped ring.
The gasket is a rubber gasket.
When the automatic exhaust valve is used, the automatic exhaust valve is arranged on the high-pressure pump, when the high-pressure cleaning machine is started, the high-pressure pump works to push air into the automatic exhaust valve from an air inlet of the automatic exhaust valve, the air is exhausted from the spring hole and the air outlet rapidly due to the clearance between the steel ball and the steel ball hole, the steel ball moves towards the left side to press the right end of the spring and leans against the O-shaped ring, and negative pressure is formed inside the high-pressure pump rapidly at this time, so that the self-suction function is realized. When pressure is generated in the high-pressure pump body, the steel balls are pushed to be tightly attached to the O-shaped ring, and the outlet is closed, so that the high-pressure pump enters a normal working state. From the above, it can be seen that the upper automatic exhaust valve can be used in the high-pressure cleaning machine without manually opening and closing the exhaust valve, thereby reducing the irritation of operators.

Detailed Description
In fig. 1, the utility model discloses an automatic exhaust valve, including left valve body 8, right valve body 5, steel ball 3, spring 1, O shape circle 2 and packing ring 4. The center of the left valve body 8 is sequentially provided with three step holes, the inner diameters of the three step holes are coaxially communicated from small to large, the hole on the left side is an air outlet hole 9, the hole in the middle is a spring hole 7, the hole on the right side is a steel ball hole 10, and the outer surface of the right end part of the left valve body 8 is provided with threads. The spring 1 is arranged in the spring hole 7, the O-shaped ring 2 is arranged on the left side of the spring hole 10, the steel ball 3 is positioned in the steel ball hole 10, and a gap is reserved between the steel ball 3 and the steel ball hole 10. The inside right part of right valve body 5 is equipped with inlet port 6, and the inside left part of right valve body 5 is equipped with the pilot hole, and inlet port 6 communicates with each other with the pilot hole. The surface of the right end of the right valve body 5 is provided with threads, and the inner surface of the assembly hole of the right end is provided with internal threads. The internal thread matches the thread provided on the outer surface of the right end of the left valve body 8. The gasket 4 is arranged at the right side of the assembly hole, and the right end part of the left valve body 8 is screwed in the assembly of the right valve body 5. The steel ball 3 can move axially along the steel ball hole 10 in the steel ball hole 10.
