Abstract
A valve structure is provided for destroying pressure difference between incoming fluids. The valve body includes two inlet passages and a merging passage that is communicated to an outlet. A pressure-balancing device is mounted in the merging passage and includes a shaft supported by two supports or end closures. Two bladed wheels are mounted to the shaft and may be impacted by the incoming fluids to thereby destroy the pressure difference between the incoming fluids.
Claims11
A valve structure for destroying pressure difference, comprising:
- a valve body including a first inlet passage for a first fluid, a second inlet passage for a second fluid, and a merging passage communicated with the first inlet passage and the second inlet passage, the merging passage being communicated to an outlet of the valve body, the first fluid and the second fluid being capable of entering the valve body via the first inlet passage and the second inlet passage, respectively and then outputted via the outlet, the merging passage including two ends, an end closure being mounted to each said end of the merging passage;
- and
- a pressure-balancing device mounted in the merging passage and including a shaft having two ends, two supports being mounted in the merging passage for rotatably holding the two ends of the shaft, respectively, a retaining member being mounted between an associated said end closure and an associated said support for retaining the associated said support in place, two bladed wheels being mounted to the shaft to rotate therewith, whereby flow of the first fluid and the second fluid compels the bladed wheels and the shaft to rotate.
A valve structure for destroying pressure difference, the valve structure comprising:
- a valve body including a first inlet passage for a first fluid, a second inlet passage for a second fluid, and a merging passage communicating with the first inlet passage and the second inlet passage, the merging passage further being in communication with an outlet of the valve body, the first fluid and the second fluid being capable of entering the valve body through the first inlet passage and the second inlet passage, and thereafter through the outlet, the merging passage including two ends, an end closure being mounted to each said end of the merging passage;
- a pressure, balancing device mounted in the merging passage and including a shaft having two ends that are rotatably held by the end closures, two bladed wheels mounted to the shaft for rotating therewith, whereby flow of the first fluid and the second fluid compels the bladed wheels and the shaft to rotate;
- and
- each said end closure including an adjusting member mounted thereon, the adjusting member rotatably holding an associated end of the shaft and being turnable for adjusting its holding tightness to the shaft.
