Abstract

The invention discloses a pipeline joint for balancing water pressure. The pipeline joint comprises a shell which is at least provided with two tap water channels and is characterized in that: impeller cavities are respectively and integrally arranged on the two tap water channels of the shell; impellers are arranged in the impeller cavities; impeller shafts and shaft sleeves are arranged among the impellers in the impeller cavities on the two tap water channels; the impellers are respectively coupled and fixed at both ends of the impeller shafts; when tap water or cool and hot water at different water pressures flows from one sides of the impeller shafts, the impellers and the impeller shafts are driven to rotate; the impellers at the side with a high water pressure drive the impellers at the side with a low water pressure to rotate synchronously, therefore, the impellers at the side with the high water pressure are used for reducing the pressure and the impellers at the side with the low water pressure are used for increasing the pressure. Accordingly, the flow rates of the tap water or the cool and hot water after passing through the impellers are approximately the same, therefore, the pressure difference of the tap water or the cool and hot water is effectively balanced.

Description

A kind of pipe coupling of balance hydraulic pressure

Technical field

The present invention relates to a kind of water supply pipe joint, especially a kind of pipe coupling of balance hydraulic pressure.

Background technique

Living standard raising along with people's door; The water tap of domestic water has all adopted hot and cold water tap mostly, and the tap water of cold water pipe and hot and cold water tap all are direct connections, and the tap water of hot-water line is to connect through the water tank and the hot and cold water tap of water heater; Like the discharge pressure of solar water heater the discrepancy in elevation from the water tank and the water outlet of solar water heater; It is different with the pressure of hot water so just to have produced cold water, and the bad more adjustment of temperature of the big more hot and cold water tap of hot water or cold water's pressure gap is though also there are some hot and cold water taps to do technological improvement; Like the patent No. be: 01276423.X has the hot and cold water tap of T-shape river diversion tee joint; Hot and cold water tap has the T-shape river diversion tee joint, and when such technological improvement was opened cold water very greatly greatly and again at hot water or cold water's pressure gap, cold water inner pipe water pressure and T-shape river diversion tee joint leading portion outlet pipe were when drenching the hydraulic pressure that hydraulic pressure in the shower nozzle is big and hot-water line is interior; Not only the hot water cold water that can not come out can flow to hot-water line on the contrary, cannot control water temperature.

Summary of the invention

Technical problem to be solved by this invention provides a kind of pipe coupling of balance hydraulic pressure; As long as the tap water of different hydraulic pressure or hot water or cold water are the pipe coupling of this balance hydraulic pressure of process; The hydraulic pressure that comes out is just basic identical, so also makes the fine adjustment of hot and cold water tap water temperature.

The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of pipe coupling of balance hydraulic pressure; Be wholely set impeller cavity respectively on two tap water passages that comprise the housing that has two tap water passages at least, it is characterized in that described housing; Be provided with impeller in the described impeller cavity, be provided with impeller shaft and axle sleeve between the impeller on described two tap water passages in the impeller cavity, described impeller is coupling respectively and is fixed on the two ends of described impeller shaft; Described axle sleeve and described housing are wholely set; The described housing that has two tap water passages is I shape, between described axle sleeve two ends, impeller shaft and axle sleeve, be provided with to be used to seal and the lining of selflubricating, the lagging material of described sealing and selflubricating like: graphite, gather four ethene not; The diameter of impeller is at least greater than a times of tap water channel diameter in the described impeller cavity; Described tap water passage impeller shaft one side in each described impeller cavity respectively passes through, and described impeller and described impeller shaft can circulate moving downstream, and described impeller cavity is provided with the impeller mount inlet; Described mount inlet is provided with lid; Be provided with seal ring between the housing of described lid and described impeller mount inlet, the gap between described impeller extension and the described tap water vias inner walls is less than 1MM, and the gap between described lid and the described impeller is less than 1MM; Gap between described impeller cavity inwall and the described impeller is less than 1MM; Describedly be arranged on two impeller cavity and impellers symmetries on the tap water passage, described two tap water passages symmetry, the two ends of described two tap water passages are respectively arranged with the screw thread that is connected with other pipeline.

Compared with prior art, the invention has the advantages that on two tap water passages of housing to be wholely set impeller cavity respectively, be provided with impeller in the impeller cavity; Article two, be provided with impeller shaft and axle sleeve between the impeller in the impeller cavity on the tap water passage, described impeller is coupling respectively and is fixed on the two ends of described impeller shaft, when the tap water of different hydraulic pressure or hot water or cold water from impeller shaft one effluent out-of-date can impeller and impeller shaft rotate; One side impeller that hydraulic pressure is big can drive the little one side impeller of hydraulic pressure and rotate synchronously; The impeller on the big one side of hydraulic pressure has played decompression, and the impeller on the little one side of hydraulic pressure has played pressurization, and the impeller on two tap water passages and two tap water passages symmetry again; Gap between impeller extension and the tap water vias inner walls is less than 1MM; Gap between lid and the impeller is less than 1MM, and the gap between impeller cavity inwall and the impeller is less than 1MM, and the tap water or the hot water or cold water's flow that pass through like this behind the impeller are basic identical; Effectively balance tap water or hot water or cold water's pressure gap; Also make the fine adjustment of hot and cold water tap water temperature, axle sleeve and housing are wholely set, and between axle sleeve two ends, impeller shaft and axle sleeve, are provided with to be used to seal and the lining of selflubricating; Sealing and the lagging material such as the graphite of selflubricating, gather four ethene not; Splendid because of graphite stability, self-lubricating property is fine, and not ethene sealing and self-lubricating property are also fine to gather four; So not only can seepage can also not reduce the frictional force between impeller shaft and the lining, impeller is reduced tap water or hot water or cold water's resistance.
