Abstract
The utility model relates to a pipeline water hammer eliminator, which is composed of a pressure regulation screw bolt, a spring, a screw cap, a valve top cover, a valve casing, a conduit, an upper valve, a lower valve, a polyporous sleeve valve and a flap valve, wherein, the pressure regulation screw bolt, the screw cap and the valve top cover are all connected by a screw thread. The side face of the valve casing is provided with an overflow port. The polyporous sleeve valve is arranged on the lower side of the upper valve. The lower valve is sheathed in the polyporous sleeve valve. The conduit is arranged on the upper valve. The spring is arranged on an inner hole of the valve top cover. The side wall and the bottom of the polyporous sleeve valve are provided with a plurality of holes. The outer side of a side wall hole is provided with the flap valve. The utility model can simultaneously eliminate the pipeline positive pressure water hammer and negative pressure water hammer of farmland lifting irrigation.
Description
The utility model relates to a kind of pipeline water hammer cancellation element, eliminates in particular for the positive and negative pressure water hammer of the pipeline of farmland irrigation by pumping.
At present, the motor-pumped well of domestic field irrigation, the water conveyance pipeline project of pumping plant and spray is irrigate, the water conveyance pipeline project of slight irrigation development is very fast have improved the efficient that farmland water-saving is irrigated greatly.But, in the pipeline water delivery process, because starting mode of pump and stopping and the factors such as opening and closing of valve, very easily form water hammer pressure, directly close the valve water hammer as producing, or during because of termination of pumping generation pump-stopping water hammer, water hammer pressure can reach 3～5 times of normal operating pressure because of instantaneous throttle down, the destruction that exceeds the bursting pressure of pipeline and cause pipe-line system is caused very big loss.At present, also good without comparison method and facility can be eliminated the water hammer negative pressure and the malleation of pipeline simultaneously, exempt from the destruction of water hammer pressure with the protection pipeline.For a long time; traditional way of subduing the pipeline water hammer pressure is surge tower or the venting stack that certain altitude is set at the head end section of pipeline or intermediate section; when pipeline produces the water hammer malleation; surge tower or venting stack raise water level increase-volume; to subdue pipeline water hammer malleation; when pipeline produces the water hammer negative pressure; surge tower or venting stack will subtract to hold reduces water level; cut down pipeline water hammer negative pressure; protect the safety of pipe-line system with this, but the drawback of this device is the cost height, construction inconvenience; the insufficient sensitivity height of elimination water hammer in service; and the height of surge tower or venting stack also is subject to certain restrictions, and that can not repair is too high, takies the farmland and ploughs; huge monster stands in great numbers in the field, hinders the field environment.
The purpose of this utility model provides a kind of multifunctional pipe water-hammer arrester that is used for the farmland irrigation by pumping, with malleation water hammer and the negative pressure water hammer of eliminating pipeline in the irrigation by pumping of farmland simultaneously.
The purpose of this utility model realizes by following solution:
The multifunctional pipe water-hammer arrester is by regulator bolts, spring, nut, the valve top cover, valve casing, conduit, last valve, lower valve, porous casing valve and flap valve are formed, regulator bolts with scyewed joint on nut, nut with scyewed joint on the valve top cover, the valve top cover with scyewed joint on valve casing, there is a flow-off side of valve casing, be provided with valve seat in it, in order to support valve, the porous casing valve is installed in the below of valve, lower valve is sleeved in the porous casing valve, and conduit is installed on the valve, and spring is contained in the valve top cover endoporus, the sidewall of porous casing valve and bottom are provided with a plurality of holes, are provided with flap valve outside the areole of porous casing valve.
During use, pipeline head end or intermediate section are installed the multifunctional pipe water-hammer arrester near water pump, when termination of pumping or pass valve pipeline generation water hammer malleation (in the Set pressure value), move on the lower valve in the porous casing valve of water pressure pushing pipeline water-hammer arrester, to go up the valve port lid, liquid that can not leaks into atmosphere; When the water hammer malleation that produces surpassed setting valve, water pressure pushed away porous casing valve and upper and lower valve on together, and water body flows out flow-off from the valve seat of valve casing, eliminates positive pressure; When pipeline produced the water hammer negative pressure, negative pressure moved down lower valve, and the flap valve on the porous casing valve is inhaled by outside tiltedly below and opened, and air through the hole of last valve and the hole of porous casing valve, enters the pipeline tonifying Qi from flow-off, thereby eliminates negative pressure.
The utility model compact structure can be eliminated the malleation water hammer and the negative pressure water hammer of pipeline in the field irrigation simultaneously.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment: Fig. 1 has provided structural representation of the present utility model, mainly partly is made up of regulator bolts 1, spring 2, nut 3, valve top cover 4, valve casing 5, conduit 6, last valve 7, lower valve 8, porous casing valve 9 and flap valve 11 etc.Have on the valve casing 5 to have flap valve 11 and to advance weep hole 12 for having on the mouth of pipe of superpressure overflow, the last valve 7 on port 10, the porous casing valve 9.Lower valve 8 is set in the porous casing valve 9, and porous casing valve 9 is to be threaded on the valve 7.The effect of associations such as last valve 7, lower valve 8, porous casing valve 9 and flap valve 11 is: when pipeline produces water hammer malleation (in the Set pressure value), move on the water pressure pushing lower valve 8, the port 10 on the last valve 7 is covered, water body can not leak into atmosphere; When the water hammer malleation that produces surpassed the Set pressure value, the tension force that water pressure overcomes spring 2 pushed away valve 7 on the porous casing valve 9 and lower valve 8 on together, and water body overflows outside the valve casing 5 through the gap of porous casing valve 9 with valve casing 5, eliminates the pipeline positive pressure; When pipeline produced the water hammer negative pressure, lower valve 8 moved down, and the flap valve 11 of porous casing valve 9 is opened automatically, and the outer air of valve enters the pipeline tonifying Qi through the port and the flap valve 11 of last valve 7, eliminates pipe negative pressure power.
