A pressure stabilizing device used in a water flow standard device and a stabilizing method thereof

Abstract

The invention discloses a pressure stabilizer used for a water flow standard device and a flow stabilizing method thereof. The pressure stabilizer comprises a water inlet pipe, a water inlet flow passage, a first layer water momentum eliminator, a second layer water momentum eliminator, a third layer water momentum eliminator, an inner cavity water inlet, an inner cavity side wall, a testing wateroutlet pipe, an anti-vortex cover plate, a cover plate supporting frame, a concave flow passage, a redundant water flow passage, a redundant water sewer pipe, a bottom wall, an outer wall, a first level water momentum eliminating device and a water inlet flow passage side wall. Water flow enters the first level water momentum eliminating device through the water inlet pipe, an eliminating effectis achieved on water momentum, the water flow successively passes through the first layer water momentum eliminator, the second layer water momentum eliminator and the third water momentum eliminator,the water momentum is completely eliminated, the water flow enters an inner cavity through the inner cavity water inlet, the whole inner cavity is filled with water, water is stably supplied to the water flow standard device through the testing water outlet pipe, and redundant water enters the redundant water flow passage for recycling through the concave flow passage arranged on the upper portion of the pressure stabilizer.

Description

technical field [0001] The invention relates to a pressure stabilizing device used for a water flow standard device and a flow stabilizing method thereof. Background technique [0002] At present, the closed type voltage stabilizing device is mainly used in the water flow standard device. This type is generally a closed water storage container welded by stainless steel and other pressure-resistant materials, which can withstand a certain pressure. It has a water inlet and a water outlet. The water port is connected with the water pump for filling water into the water storage container; the water outlet is connected with the water inlet of the water flow standard device for supplying water to the water flow standard device. The function of this type of pressure stabilizing device is to isolate the water flow standard device and the water pump, eliminate the water supply pulsation of the water pump and the air bubbles in the water, and continuously supply water to the closed p...

AI Technical Summary

Problems solved by technology

However, there are still insurmountable shortcomings in use: the complete isolation of the water pump and the water flow standard device cannot be realized, and the pressure fluctuation caused by the water supply pulsation of the water pump and the pulsation to the pressure stabilizing device cannot be completely eliminated, and the water flow of the water flow standard device is stable. Therefore, this type of voltage stabilizing device is generally used in water flow standard devices with large uncertainty and low requirements on water flow stability.
