Description

Fluid circulation system with high-low pressure conversion function Technical Field The utility model relates to the technical field of circulating pipelines, in particular to a fluid circulating system with a high-low pressure conversion function. Background In a fluid delivery system, sometimes high-pressure fluid needs to be introduced into a using device, in order to ensure the fluid flow, the pressure of circulating fluid in the system is higher than the using pressure of the using device, the using device cannot be directly used, and the backwater pressure in a high-pressure circulating pipeline is lower than the water supply pressure, but still higher than the using pressure of the using device, the fluid needs to undergo a high-pressure-low-high-pressure change process in the process of flowing through the using device, and the using device has low using pressure but high flow requirement, so a set of high-low pressure conversion structure needs to be designed in the circulating system, and the pressure and the flow in the pipeline are ensured to meet the using requirements of the circulating system and the using device. Disclosure of utility model The utility model provides a fluid circulation system with a high-low pressure conversion function, which solves the problem that the pressure and the flow of fluid in a high-pressure pipeline and using equipment are not compatible. In order to achieve the technical purpose, the utility model adopts the following technical scheme: The utility model provides a fluid circulation system with high low pressure conversion function, includes delivery pipe, wet return, user equipment, and delivery pipe one end connects gradually pipeline filter, relief pressure valve, user equipment's water inlet end, and wet return one end connects gradually check valve, circulating pump, user equipment's water outlet end, and delivery pipe other end and wet return other end connect the circulation pipeline. Further, a first manual valve is connected between the filter and the water supply pipe. Further, a manual valve II is connected between the check valve and the water return pipe Further, the water supply pressure of the water supply pipe is 0.4-0.6Mpa, the backwater pressure of the backwater pipe is 0.38-0.58Mpa, and the using pressure of the using equipment is less than 0.3Mpa. Further, the self-priming pressure of the circulating pump is 0.05-0.25Mpa. Compared with the prior art, the utility model has the beneficial effects that: The utility model can effectively and safely apply the equipment with lower pressure requirement but higher flow requirement to the high-pressure fluid circulation system, ensure the stable operation of the system and prolong the service life of the equipment.
