Technical Field
The utility model relates to a pressure gauge, in particular to an inlet runner structure of the pressure gauge and the pressure gauge.
Background
In the prior art, when the pressure gauge works, pressure fluid can directly flow into the pressure gauge through the pressure gauge hole, so that parts in the pressure gauge are continuously impacted by the pressure of the fluid, and finally, the service life of internal parts is easily shortened. In addition, possible impurities in the fluid enter the pressure gauge, so that the pressure pointer fails to rotate, and the pressure gauge is corroded, cracked, leaked and the like in severe cases.
How to provide a device capable of effectively protecting internal parts of a pressure gauge is a problem to be solved urgently by technical personnel in the field at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art, provides a device for effectively protecting internal parts of a pressure gauge, and particularly provides an inlet channel structure of the pressure gauge and the pressure gauge.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
an inlet flow channel structure comprises a meter seat, wherein a fluid channel is arranged on the meter seat, a bolt body matched with the fluid channel is arranged in the fluid channel, a spiral flow channel cavity used for reducing the impact force of fluid is arranged between the bolt body and the inner wall of the meter seat, and two ends of the spiral flow channel cavity are respectively communicated with a water inlet and a cavity body at the inner end of the meter seat.
The working principle of the utility model is as follows: water flow enters from an inlet of the spiral flow channel cavity, then the direction of the water flow is changed, the water flow enters the interior of the spiral flow channel cavity in a rotating mode, the spiral flow channel cavity plays a role in blocking and slowing down, the pulse impact of fluid on internal parts of the pressure gauge is reduced, and the structure of the pressure gauge is protected.
Preferably, the meter seat inner wall is provided with a spiral groove, the spiral groove is composed of a groove body and a groove wall, the outer wall of the plug body is abutted to the top end of the groove wall, and a continuous cavity formed between the groove body and the outer wall of the plug body forms a spiral flow passage cavity.
Preferably, the outer wall of the bolt body is provided with a spiral groove, the spiral groove is composed of a groove body and a groove wall, the inner wall of the gauge stand is abutted to the top end of the groove wall, and a continuous cavity formed between the groove body and the inner wall of the gauge stand forms a spiral flow passage cavity.
The two optimal schemes are parallel schemes, the structure mode of the spiral runner cavity is introduced, any one of the two modes can achieve the purpose of the utility model, and the two modes can be selected according to the requirement during the specific processing.
The utility model also discloses a pressure gauge with the pressure gauge inlet runner structure.
