Description
Technical field
The utility model belongs to the hydrant device of a kind of aqueduct in the aqueduct technical field.
Background technology
Along with the extensive use in continuous application and expansion, the especially farmland buried plastic delivery hose road of aqueduct, also just more and more higher to the specification requirement of its supporting connection aqueduct waterworks.Because the aqueduct of agricultural, can be protected pipeline and convenient the use effectively by buried.One of topmost connector in the existing buried water delivery pipeline system is the hydrant device.In known technology, common aqueduct hydrant device mainly is the vertical rod that is connected and fixed by in the threeway that is loaded on the road load of buried water-main, and vertical rod the higher authorities load hydrant head is formed.But limit by its structure, it connects complicated, uses loaded down with trivial detailsly, because it all is exposed to 20～30cm place on the ground level to the head of hydrant, it highly fixes non-telescoping conversion.Now, from ploughing, sow, apply fertilizer, use agricultural chemicals up to crops ripe and harvested, transportation, all carried out mechanization production at large in the agricultural production.Mechanization is produced and has been improved labor productivity, but, also simultaneously the aqueduct hydrant device of finishing the farmland irrigating engineering transformation very serious threat and destruction have been constituted, the hydrant head is the plane projectedly, its vertical rod mostly is the metal welded tube or plastic tube is made, be not resist mechanical backing and bump, and cause vertical rod to rupture or buried primary pipe rupture, making water conveyance irrigation equipment cisco unity malfunction, is after the crops harvesting at north cold area especially, must all discharge the water in the buried pipe before freezing, water bursting by freezing pipeline in preventing from managing, have a lot of rainwater in the pipeline, go over such winter, when irrigation installation is used to spring in the coming year, will find that pipeline the bursting by freezing damage occurs in many places, repair the effort of getting up to take a lot of work, economic loss is huge, brings inconvenience to use.
Summary of the invention
In order to overcome the deficiencies in the prior art, solve existing aqueduct hydrant device easily by mechanical failure and the problem that the bursting by freezing damage occurs.The purpose of the utility model provide a kind of simple in structure, the assembling simple and easy, utilize piped water self pressure, having of designing in conjunction with hydraulic principle can promote plane highlightedly automatically, new-type aqueduct hydrant device time saving and energy saving, easy to use.
The utility model addresses the above problem the technical scheme of taking:
A kind of scalability hydrant device, it is provided with: water delivery trunk line, threeway, telescopic joint sleeve pipe, flexible pole, telescopic joint sealing gland, threeway is that the compound speed of elastic packing connects type pipeline reducer tee, compound speed connects in the two ends that type pipeline reducer tee connects the water delivery trunk line respectively the side of being equiped with from leakage seal cushion rubber, sealing ring and O type O-ring seal, be provided with an O type O-ring seal and first party in the telescopic joint sealing gland from the leakage seal cushion rubber, telescopic joint masthead portion connects the telescopic joint top pressure closure.
Above-mentioned scalability hydrant device, described telescopic joint masthead portion or load hydrant valve head and quick water intake valve.
Above-mentioned scalability hydrant device, described flexible pole are that the best flexible pole by the 2-4 joint of 1-8 joint is formed.
Above-mentioned scalability hydrant device, the two ends of described telescopic joint sleeve pipe are provided with external screw thread, and the lower end external screw thread connects type pipeline reducer tee 2 with compound speed and is connected, and upper external screw thread connects telescopic joint sealing gland 4.
Above-mentioned scalability hydrant device, described flexible pole are that the upper end is provided with the flexible pole that external screw thread, lower end have been provided with the position-limiting action boss.
When the utility model uses, by designing requirement this novel scalability hydrant device is installed successively and to be connected on the buried water delivery trunk line, the buried degree of depth can be determined according to the situation of cultivating, the hydrant device top that generally is in retracted state apart from the ground level degree of depth be 20～40cm for well, can avoid the generation of destroyed accident like this.When irrigation installation is used, open water system, be full of water in the pipeline, when hydraulic pressure reaches certain pressure (general hydraulic pressure is more than 0.2～0.3MPa), the head of scalability hydrant device will automatically be given prominence to and bury soil, highly rises to ground level 25～30cm, is in and treats duty.After a production cycle finishes, irrigation installation is no longer used when not having hydraulic pressure in the pipeline, the reliable free return of its extension, but a little strength of giving that the very important person is help return, when if soil block foreign material etc. have resistance, should carry out the labor cleaning once, make it thoroughly retract to design safety point original position.
Go up technique scheme because this new design adopts, solved existing aqueduct hydrant device effectively easily by mechanical failure and the problem that the bursting by freezing damage occurs.Testing result on trial for several times through North China, the Northeast shows, it have simple and practical, the assembling simple and easy, utilize piped water self pressure, having of designing in conjunction with hydraulic principle can promote plane highlightedly automatically, advantage such as time saving and energy saving, easy to use, be applicable to the irrigation and water conservancy irrigation project of agricultural, and other aqueduct etc.
