Abstract
The utility model discloses a device for preventing and releasing water hammer pressure of a pump station. The device for preventing and releasing the water hammer pressure of the pump station comprises a pumping unit (1), wherein the pumping unit (1) is provided with a pressure water conveying main pipe (2), and a control valve (3) is arranged between the pumping unit (1) and the pressure water conveying main pipe (2). The device for preventing and releasing the water hammer pressure of the pump station is characterized in that the pressure water conveying main pipe (2) is provided with two pressure release pipelines (4), one pressure release pipeline (4) is provided with a water hammer prevention valve (5), and the other pressure release pipeline (4) is provided with a water hammer release valve (6). Due to the adoption of the technical scheme, in the running process of the pump station, the device for preventing and releasing the water hammer pressure of the pump station can detect the water pressure on the pressure water conveying main pipe of the pump station and carry out pressure release adjustment, and thus the water pressure on the pressure water conveying main pipe can be controlled within an allowed range.
Description
Technical field
The utility model relates to a kind of device that prevents and release the pumping plant surge pressure, belongs to the pumping plant technical field in plumbing.
Background technique
Be provided with the supply and drain water system of pumping plant in water conservancy, municipal engineering, during because of accident outage suddenly or other reasons (driving valve) termination of pumping suddenly, make flow rate of water flow in water-carriage system occur to change suddenly, cause sharply rising or the decline of water flow pressure in the water-carriage system pipeline simultaneously.The interior pressure jumpy of this water-carriage system pipeline is surge pressure both, and surge pressure surpasses the design permitted value will produce destruction to water-carriage system, the normal activity in production of living of impact, the safety of serious threat to life property.If can take the generation of rational engineering measure prevention water hammer accident in the design process of pumping plant water-carriage system, with regard to the possible system surge pressure being controlled in the design allowed band, the construction investment of water-carriage system can not only be reduced, and the impact of water hammer accident on productive life can be reduced.
Summary of the invention
The purpose of this utility model is to provide a kind of engineering measure of protecting water hammer, and a kind of device that prevents and release the pumping plant surge pressure, to improve the Security of pressure water pipe system, thereby overcome the deficiencies in the prior art specifically.
For realizing the purpose of this utility model, the utility model has adopted such technological scheme: the device of prevention of the present utility model and the pumping plant surge pressure of releasing comprises water pump assembly, this water pump assembly is provided with the pressurized water transmission main, be provided with control valve between water pump assembly and pressurized water transmission main, wherein on aforesaid pressurized water transmission main, be provided with two relief pipelines, a relief pipeline wherein is provided with water attack prevention valve, and another root relief pipeline is provided with water attack release valve.These two relief pipelines are preferably and are arranged in parallel.
Further, also be provided with service valve on aforesaid relief pipeline.This service valve is between described water attack prevention valve or water attack release valve and pressurized water transmission main.Service valve is used for cutting off the passage of relief pipeline and pressurized water transmission main when the parts such as maintenance relief pipeline and water attack prevention valve and water attack release valve.
Owing to having adopted the technical solution of the utility model, in the pumping station operation process, device of the present utility model can be detected the water pressure on the pressurized water transmission main of pumping plant, and carries out the pressure release adjusting, thereby the water pressure on the pressurized water transmission main can be controlled in allowed limits.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as of accompanying drawing: 1-water pump assembly, 2-pressurized water transmission main, 3-control valve, 4-relief pipeline, 5-water attack prevention valve, 6-water attack release valve, 7-service valve.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
When water pump assembly 1 operation, water attack prevention valve 5 is by the pressure on detecting pressure delivery main 2, and when the pressurized water transmission overpressure drops to suddenly the force value that water attack prevention valve 5 adjusts, water attack prevention valve 5 is opened, start to carry out in advance pressure release, play the effect of prevention surge pressure.After 5 actions of water attack prevention valve, if the surge pressure in aqueduct continues to continue to rise, when the pressure rise value reaches the force value that water attack release valve 6 adjusts, water attack release valve 6 is opened and is carried out pressure release, and the pressure of water-carriage system is controlled in the scope that design allows.
be more than a concrete exemplary applications of the present utility model, the utility model also has other mode of execution, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
