Description

Water-saving hammer two-stage water-saving and energy-saving ceramic valve core

The invention relates to a "waterproof hammer two-stage water-saving and energy-saving ceramic valve core", in particular to a ceramic valve core that can save water and energy, and can effectively eliminate the phenomenon of water hammer.

According to the press, the use of the faucet is mainly provided by the handle of the ceramic valve core provided by the handle, and the faucet can be boiled when the handle drives the valve stem to pull. When the water source is turned on, the change in the rotation range of the handle can be used to adjust The mixing ratio of cold and hot water even flows out with cold or hot water alone.

However, the conventional structure described above still has the following problems in practical application: (1) When the handle is pulled up, the stop can only be generated at the two positions of full water and full water, and the middle stroke is not Due to restrictions, when the user pulls the handle of the faucet with a general force, the water volume is often directly opened to the maximum, which will cause the precious water resources to be wasted in vain, which is quite unfriendly to the environment; ( 2) If the water volume of the faucet is turned on and then turned off suddenly, you will often hear a huge sound from the water pipe, sometimes accompanied by strong vibrations. This phenomenon is called "water hammer". This is because the water flow The continuous outflow, but the front outlet suddenly closed, causing the rear water waves to push forward, and a large number of concentration, and caused the sudden increase in the density of the water flow, and the ceramic valve core of the conventional faucet did not prevent the water hammer phenomenon. Happen, let the huge energy of the water hammer often It may cause damage to the faucet or water pipe.

Therefore, the present inventor was thinking about the idea of creation in view of this, and designed it based on many years of experience. After many discussions and trials, he experimented with samples, and revised and improved many times to launch the invention.

The ceramic valve core of the conventional faucet cannot save water and energy, nor can it eliminate the water hammer phenomenon in the water pipeline. This is a technical problem to be solved.

The invention provides a two-stage water-saving and energy-saving ceramic valve core of a waterproof hammer. The ceramic valve core is provided with a rotating seat, a linkage block, a movable valve disc, and a valve body, which are sequentially stacked from top to bottom in a valve housing. A fixed valve disc, a rotating seat central group has a valve stem protruding upward from the valve housing, the coupling block at the bottom end of the valve lever is used to fasten the linkage block, and the linkage block is embedded with the movable valve disc, and can pass through the valve. The operation of the lever drives the moving valve plate to translate, or rotate after translation. 俾 Use the change of the alignment relationship between the moving valve plate and the fixed valve plate to control the faucet to turn on and off the water, or change the mixing ratio of cold and hot water. And the amount of water flow, a valve seat is used below the valve housing to stop the fixed valve disc, the movable valve disc, the linkage block and the rotary seat from falling out, and an adjustment unit is installed on the linkage block, of which the rotary seat The bottom surface has two side flanges, and the two side flanges can be used to project the two side flanges. A sliding groove is formed in the middle, and a limit pin protruding slightly from the inner surface is embedded in the middle section of the two side retaining edges. A claw portion protrudes downward from one end of the sliding groove, and a shrinkage is provided above the linkage block. Diameter socket sections, each side of the socket section is formed with a convex part, and the socket section is sleeved in the slide groove of the rotary seat, so that the linkage block can be moved in the slide through the valve rod. The tank is driven to move in translation by the valve rod, and a communication tank and a water control chamber are provided on the peripheral side and the bottom surface of the linkage block to communicate with each other. The adjustment unit is provided for the installation of the storage tank for installation. The valve seat is provided with a cold water inlet hole, a hot water inlet hole and a water outlet hole, and a fixed valve plate is provided with a cold water inlet hole which is aligned with the cold water inlet hole, hot water inlet hole, and outlet hole. A hot water passage hole and a water outlet through hole, a through hole is penetrated on the movable valve plate, and the upper edge of the through hole is enlarged into a mixing chamber. When the linkage block, the movable valve plate, and the fixed valve plate When the valve seats are sequentially stacked, and the fixed valve plate is fixed on the valve seat, the movable valve plate is ordered The mixing chamber can be directly aligned with the water control chamber of the linkage block, so that the two can be conducted smoothly. The piston of the adjustment unit has a first end and a second end, and a ring groove is provided on the outer periphery of the first end. When the piston is inserted with the second end toward the receiving groove of the linkage block, the protrusion of the first end can be used to use the ring groove to provide the claw portion of the rotary seat for buckling, and The outer peripheral sleeve of the piston inserted into the volume groove has at least one water ring, thereby obtaining a two-stage water-saving and energy-saving ceramic valve core of a waterproof hammer.

(1) The two-stage water-saving and energy-saving ceramic valve core of the waterproof hammer of the present invention, the ceramic valve core can perform two-stage water discharge, so that the water flow can choose a small flow or a large flow according to the needs of the user. Only when the water is used, the faucet is directly opened to the maximum, and the hard-to-obtain water resources are wasted in vain, and the use will be more environmentally friendly.

(2) The two-stage water-saving and energy-saving ceramic valve core of the waterproof hammer of the present invention uses the cooperation of the claw, the water control chamber, the tank and the piston to pump water into the tank or to the water control chamber at the moment of opening and closing Refilling in the middle can effectively prevent the occurrence of water hammer, so as to achieve the advantage of more durable faucets or water pipes.
