Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-3, a pressureless tap for hot water, the tap includes a control assembly and a pressure release mechanism, the control assembly is provided with an operation handle 21, the operation handle 21 is connected with a control link 22 for controlling the horizontal movement of the control link 22, the other end of the control link 22 is used for connecting a valve core 28, connection is realized by rotating, the butt joint of installation implementation is convenient, the end of the control link 22 is provided with a connection cover 27, the connection cover 27 assists the butt joint to the mandrel of the valve core 28, connection is realized by rotating a certain angle, the valve body of the control valve 201 is arranged in the shell 12, the control valve 201 is of the existing horizontal movement structure, the valve core 28 is positioned in the valve 29 and sealed to realize blocking of water flow, after the valve body is installed in place, a sealing nut at the upper end of the valve body is installed, the sealing nut is connected with a water outlet 11, the sealing nut is fixedly connected with a water receiving pipe 13 through the nut at the lower end, and the outer part of the water receiving pipe 13 is provided with a mounting disc 14 to realize dust prevention and sealing of the connection structure. The outward movement of the operating handle 21 controls the water outlet by controlling the degree of separation of the valve core 28 and the valve 29 driven by the connecting rod 22.
For the water outlet, it should be noted that, due to the adoption of the pull-type separation structure and the pressure release structure, the bottom of the valve body is provided with a pair of water inlets and water return ports towards the left side shown in fig. 1, and the water inlets and the water return ports are communicated with the water flow channel in the valve body in a rotary mode, the diameters of the water inlets and the water return ports are preferably 2mm-5mm, the water inlets and the water return ports are used for pressure release of the small water flow channel, and the thinner water inlets and the thinner water return ports can also cause relatively higher water flow speed. In this case, the tesla valve of the present invention has a very good pressure relief effect.
Regarding the structural principle of tesla valves, those skilled in the art will know that the valve has wide application in fire protection and exhaust equipment.
The tesla valve is one of the applications of the pressure release mechanism of the invention, adopts reverse installation to realize pressure release, and also comprises other modes such as a one-way exhaust valve, wherein the inner wall of the tesla valve 35 is fixedly connected with a plurality of flow dividing blocks 37, the inner wall of the tesla valve 35 is fixedly connected with a plurality of main launders 36, and the top of the tesla valve 35 is provided with an exhaust hole 38. In operation, the energy of the water flow is suppressed by the tesla valve 35, so that the water flow cannot flow out through the tesla valve 35, the gas is separated from the fluid, the internal branch cannot suppress the flow of the gas, and the gas is discharged out through the exhaust hole 38.
Described herein are: the exhaust of the Tesla valve can be collected or discharged by using an external pipeline, and the contact of the Tesla valve during the operation of the handle is avoided.
In one of the improvement modes of the invention, the left side of the shell 12 adopts a detachable sealing structure, so that the disassembly and maintenance in the fault process can be realized, and the judgment on whether the valve body has a through section fault or not is realized by judging whether the interior of the valve body is blocked or not by looking at whether the water inlet and the water return port are out of water or not. Further, the water inlet and the backwater port of the valve body are likely to be easy to precipitate or exist other ions, so that the activated carbon 33 can be further arranged to solve the problem of purifying water. The activated carbon 33 allows impurities in water to be adsorbed, has an obvious purification effect on water for cold water, and can be selectively added when applied to hot water.
The structure of the control link 22 will be further described. The control connecting rod 22 runs through fixedly to be sleeved with the piston disc 23, one side of the piston disc 23 is fixedly connected with four screw rods 24, the periphery of each screw rod 24 is fixedly sleeved with a limiting disc 25, each limiting disc 25 is fixedly connected with the control connecting rod 22, one side of each screw rod 24 is movably sleeved with a nut 26, the structure can be regarded as a large piston, the control connecting rod 22 moves, the piston disc 23 is attached to the inner wall of the shell 12, the limiting discs 25 are limited by arranging concave parts on the corresponding inner walls, and correspondingly, the valve core 28 and the valve 29 can be opened and closed.
In the invention, the piston disc 23 and the limit disc 25 on the control connecting rod 22 can play a supporting role of the operating handle, so that the problem that the existing valve core is supported and stressed by the valve body, and the loosening can occur in the long term in the prior art is avoided, and the valve core is also one of reasons that the conventional water valve operating handle is attached to the valve body. The screw 24 and the nut 26 between the piston disc 23 and the limiting disc 25 are fixed, the supporting property of a large piston is stronger, the piston disc 23 moves in the shell 12 more stably, the operating force of the operating handle 21 can be balanced when a certain resistance is received, and the existing faucet is not accurate enough in water flow control, especially the eversion operating handle 21. On the other hand, the valve core and the valve can be maximized, the opening and closing degree of the valve core is maximized, the existing valve core needs to be considered for sealing, such as a ball valve, the through hole in the middle is relatively smaller than the water flow channel, and the valve core can not fall off. However, in the invention, even if the sealing edge is narrow and water leakage exists, the piston disc 23 is controlled in the shell 12 and cannot flow out, and the water inlet and the water return port cannot cause leakage under the pressure condition.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
