Abstract
The invention belongs to the technical field of pipeline valves and particularly relates to a constant-flow gap type inlet and outlet capable of eliminating the influence of viscosity. The constant-flow gap type inlet and outlet comprises a gap, a plug body, an adjusting wall, an adjusting channel, a spring support block and the like. The middle of the plug body is provided with the gap. When pressure on the two sides of the plug body is different, a flowing medium flows into the other side through the gap under the action of the differential pressure. When the flowing medium flows through in the plug body, the sum of the elastic force of an auxiliary spring and the pressure of the adjusting channel and the pressure generated by the gap achieve balance, and thus the adjusting wall is in a stable state. After temperature is decreased and the viscosity is increased, the pressure loss in the adjusting channel is increased more than the pressure loss in a gap channel, the auxiliary spring needs to be further compressed so that the stress of the adjusting wall achieves new balance, therefore, the adjusting wall moves to the direction of the adjusting channel, the gap is enlarged, the increased gap makes up the reduction of flow and speed due to the increase of the viscosity of the flowing medium, the temperature influence is weakened, and a good usage effect is achieved.
