Precision ceramic control valve with seat structure

The invention relates to a "precision ceramic control valve mating seat structure", in particular to a precision ceramic control valve mating seat structure which can prevent the sealing member from being scraped or broken during the assembly process.

In view of the fact that the conventional faucet needs to have a longitudinal partition in the compartment to effectively separate the cold and hot water, the inventors have developed a precision ceramic valve suitable for the non-separator faucet. The state is as disclosed in the sixth to the ninth, or the national patent certificate No. M500836, wherein the precision ceramic valve (50) is used in conjunction with the faucet body (60), and the precision ceramic valve (50) The system comprises a valve body (51), a valve seat (52) and a sealing member (53), wherein the valve body (51) has a valve housing (511), and a valve stem (512) is mounted in the valve housing (511). With the two valve pieces, the valve stem (512) is used to provide the operating system so that the two valve plates can be aligned or offset from each other, and used to control the switching water or change the mixing ratio of the cold and hot water, and the valve seat (52) is fixed. Below the valve body (51), and having a top plate (521), the top plate (521) is provided with a first-class outlet (522), and the two sides of the outflow port (522) are arranged at intervals on the bottom surface of the top plate (521). There is a water inlet conduit (523), which is provided with two adjacent walls (5231), an outer arc edge (5232) and an inner retaining wall (5233). Its bottom surface lines were closed, and the top plate (521) relative to the position of two inlet conduit (523) to a respective water-passing holes (524) Passing down into the inlet conduit (523), the two inlet conduits (523) are each passed through a cold and hot water inlet (5234) through the outer arc edge (5232), and on the bottom surface of the second inlet conduit (523). Extending at least one positioning leg (525), the sealing member (53) includes a first ring (531) having a longitudinal shaft hole, and a lateral shaft hole is respectively connected to each of the first ring (531) a second ring (532), the first ring (531) is sleeved on the outer periphery of the top plate (521) of the valve seat (52), so that the second ring (532) can be nested in the water inlet conduit On the side edge and the bottom surface of (523), the faucet body (60) is integrally cast, and a water dividing chamber (61) and a water control valve chamber (62) connected to the upper and lower sides are arranged in the center of the center, and the water control valve chamber is (62) The upper part is penetrated by an opening (621), and the lower part is connected with the water dividing chamber (61) through a stepped ring protrusion (622) of a reduced diameter, and the rear side of the faucet body (60) is divided into two parts. A cold water inlet (63) and a hot water inlet (64) are provided. The cold water inlet (63) and the hot water inlet (64) are cold water inlet passages on both sides of the faucet body (60). ), after the hot water inlet channel (66) is turned on, each Directly through a horizontal perforation (611) into the water separation chamber (61), through the water outlet (612) in front of the water separation chamber (61) to communicate with the outlet pipe (67) of the faucet body (60), and also enable cold and hot water From the water outlet (612), the outlet pipe (67) is separately discharged or mixed and then flows out together, and the bottom surface of the water dividing chamber (61) is provided with a limit for the positioning of the precision ceramic valve (50) positioning pin (525). Bit hole (613).

In use, the precision ceramic valve (50) is placed in the water control valve chamber (62), and the retaining ring is locked on the threaded section of the opening (621) by a retaining ring to compress the precision ceramic valve (50). The nesting of the sealing member (53) is forced between the top plate (521) and the stepped ring projection (622), between the water inlet conduit (523) and the inner wall and the bottom surface of the water dividing chamber (61), and the precision ceramic valve is ordered. The use of (50) produces a good deadlock effect.

However, the inventor did not become complacent after developing the creation case. In the spirit of excellence, we continue to think about R&D, and strive to make this structural feature more vivid and easy to use. The inventor found in the subsequent development process that the above-mentioned pre-case structure still has the following problems in practical application. : The precision ceramic valve (50) with the sealing member (53) is placed into the faucet body (60) from top to bottom, and the direct insertion is often caused by slight error in the processing precision of the faucet body (60). , or the burrs are not properly removed, causing the sealing member (53) to be scratched or scratched by the faucet body (60) during the insertion process, and the assembly is prone to sputum.

Therefore, the present inventors have invented the present invention in view of the fact that the idea of creation and creation has been designed with many years of experience, and has been explored and tested by various parties, and has been repeatedly modified and improved.
