Along with developing rapidly of science and technology, pressure fluctuation Continuous Absorber have also been obtained technological improvement, but present equipment absorbability is poor, is unreachable to seriality, easily causes compression shock, frequency range is narrower, and part is complicated, apparatus expensive, poor stability, weight is big, and it is the most inconvenient to bring to user.
Utility model content
For the problems referred to above, this utility model provides a kind of pressure fluctuation Continuous Absorber, solve present equipment absorbability poor, be unreachable to seriality, easily cause compression shock, frequency range is narrower, and part is complicated, apparatus expensive, poor stability, weight is big, brings the most inconvenient phenomenon to user.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of pressure fluctuation Continuous Absorber, its structure includes: flow tube, end cover nut, end cap, sealing ring, shell, leather bag, check valve, described flow tube is connected by dividing plate and described end cover nut are fixing, described end cover nut is connected by screw and described end cap are fixing, described end cap is externally provided with described sealing ring, described sealing ring it is provided with in described shell, described shell has described leather bag, described shell is connected by dividing plate and described leather bag are fixing, described shell is arranged over described check valve, described shell is connected by nut and described check valve are fixing, it is provided with valve body in described check valve, it is provided with spool in described check valve, described spool side is provided with spring.
Further, described spool is by iron wire and spring clearance fit；
Further, described end cap and described sealing ring junction are provided with pressure transducer；
Further, described leather bag has multiple absorption plant.
From the above-mentioned description to this utility model structure, compared to the prior art, this utility model has the advantage that
This utility model one pressure fluctuation Continuous Absorber, can drive train pressure continuously by arranging flow tube, it is more firm that end cover nut can coordinate end cap to make, it is hermetically sealed that sealing ring can carry out equipment, the Small Holes passed through in pipeline after oil connection oil inlet P enters pipeline when the hydraulic oil with certain ripple frequency contacts with leather bag, reach the effect of absorption pressure pulsation, during stream flows through conduit, leather bag enough absorbs more than 2 pulsation, to form repeatedly the purpose of absorption pressure pulsation.Reducing the effect of pressure fluctuation, check valve prevents compressed air reverse flow in pneumatic system.This utility model absorbability is good, can reach seriality, it is not easy to build-up of pressure impacts, and frequency range is wider, and part is simple, and equipment is cheap, and safety is good, lightweight, brings very convenient to user.
