Referring to fig. 1-3, a swivel joint for a kitchen L-shaped faucet comprises an installation base 1, a connection pipe 2 is fixedly installed inside the installation base 1, a control valve 3 is fixedly installed in the middle of an inner cavity of the connection pipe 2, a sealing support base 4 is fixedly installed at the top end of the connection pipe 2, an internal connection pipe 5 is fixedly installed at the top end of the connection pipe 2 and right above the sealing support base 4, an adsorption extrusion layer 6 is sleeved in the middle of the outer surface of the internal connection pipe 5, a swivel sleeve 7 is fixedly sleeved on the periphery of the adsorption extrusion layer 6, the bottom end of the swivel sleeve 7 is fixedly connected with the top end of the sealing support base 4, a swivel pipe 8 is arranged at the top of the swivel sleeve 7, a sealing press block 9 is fixedly installed at the bottom end of the swivel pipe 8, an extrusion sleeve 10 is connected to the bottom of the outer surface of the swivel pipe 8 through a screw thread, and, the top end of the internal connecting pipeline 5 is in transmission connection with the inner cavity of the sealing pressing block 9 through a pressure spring 11, the top of the inner cavity of the rotating pipeline 8 is provided with a spoiler fan 12, and the spoiler fan 12 is fixedly connected with the rotating pipeline 8 through a fixing sleeve 13.
Wherein, to the setting of vortex fan piece 12 and fixed sleeve 13, can form the effect of a disturbance to the rivers that enter into rotatory pipeline 8, cause when the water of different temperatures passes vortex fan piece 12 with certain velocity of flow, can be mixed by abundant stirring and be in the same place, and then guaranteed that the temperature difference of the water temperature of giving out is less, the phenomenon of neglecting cold and neglecting hot can not appear for this rotatory tap's result of use is better.
In the technical scheme, the adsorption and extrusion layer 6 is formed by overlapping and extruding multiple layers of high molecular sponges, and edible oil is filled in the adsorption and extrusion layer.
Wherein, to the absorption extrusion layer 6, rotatory sleeve 7 and rotatory pipeline 8's setting, can form an oil blanket device in the rotatory clearance department between inscription pipeline 5 and rotatory pipeline 8, the density that utilizes edible oil is little can float on the surface of water than water, so that press water under absorption extrusion layer 6 always, in order to avoid rubber seal ring wearing and tearing to appear in long-time use, ageing phenomenon, simultaneously because edible oil's viscosity is great, for the difficult phenomenon that takes place to leak of water at its rotary seal's in-process, stability and reliability are higher.
In the present technical solution, the sealing press block 9 is made of a polymer elastic rubber material and is designed to have a hollow conical structure.
In this technical scheme, the cross section of extrusion sleeve 10 bottom is established to right triangle-shaped, and the inclination of its hypotenuse is the same with the inclination at the last toper structure top of sealing briquetting 9.
Wherein, to the setting of sealed briquetting 9 and extrusion sleeve 10 exterior structure, area of contact between can the sealed briquetting 9 of effectual increase and the extrusion sleeve 10, and then improved this rotary joint's sealed effect, can not lead to adsorbing the edible oil in the absorption extrusion layer 6 and too much the phenomenon that appears leaking of pressure because of the too much water that causes of leakage, further improve this rotary joint's stability and reliability.
In the technical scheme, the top of the inner cavity of the rotary pipeline 8 is provided with a boss structure, and the inner diameter of the boss structure is the same as that of the inner diameter of the inner connecting pipeline 5.
Wherein, to the setting of 8 inner chambers top boss structures of rotatory pipelines to convenient joint installation spoiler fan piece 12 and pressure spring 11, make its in-process of installation and work can not appear random luffing motion's phenomenon.
Wherein, the bottom of connecting tube 2 surface and the top of 8 surfaces of rotatory pipelines all are equipped with the external screw thread for the convenient intercommunication pipeline of screw thread makes this rotary joint dismouting get up convenience and practicality of comparison.
The use method and the working principle of the embodiment are as follows:
firstly, the rotary structure is fixedly arranged in the middle of two water tanks by using an installation base 1, a tap water pipe and an L-shaped faucet are installed by using threads outside a connecting pipeline 2 and a rotary pipeline 8, then an extrusion sleeve 10 is downwards rotated by using a tool and a pressure block 9 is gradually pressed and sealed, the extrusion sleeve is driven to downwards move to gradually press an adsorption and extrusion layer 6, so that the adsorption and extrusion layer 6 forms a sealing layer of compact edible oil, in the process that the rotary pipeline 8 downwards moves, a pressure spring 11 fixedly arranged in an inner cavity of the pressure spring is compressed to generate enough pressure for an inner connecting pipeline 5, then when a control valve is opened, water flows onto an L-shaped water tap through the connecting pipeline 2, an inner connecting pipeline 5 and the rotary pipeline 8 and is discharged, when the rotary structure needs to be rotated back and forth between the two water tanks and water is discharged, the water leaked from the inner connecting pipeline 5 and the rotary pipeline 8 is positioned below the edible oil due to higher density, and can't pass the tight edible oil sealing layer, and then the effectual phenomenon that prevents this rotary joint and make a round trip to rotate the in-process and leak between two basins, simultaneously under pressure spring 11's elasticity effect, when rotating screw thread fixed connection's L type tap, make it have a trend of moving down, and can not cause L type tap to appear the jam because of the tension of extrusion sleeve 10 joint when rotating, unable rotatory phenomenon for this rotary joint's stability and reliability are higher.
