Description
The present invention relates to optimizing structure of a kind of ceramic valve core.
Existing ceramic seal spool, what adopt as the water mixing valve core of angle general formula list water nozzle spool and contrary general formula all is two ceramics structures (stator and moving plates), and general straight-through type is generally three ceramics structures (moving plate of folder between the identical stator of two chip architectures), its mutual faying surface is smooth, parallel and smooth, and is equipped with corresponding valve body and sealed member is formed various ceramic seal valves.The spool of two common ceramics structures, moving plate rotate or the translation process in, also have the friction between the non-ceramics parts, often before the ceramics wearing and tearing, wear and tear already between the non-ceramics parts and cause leakage.The wear resistance of ceramics is failed whole bringing into play; And no matter angle general formula or straight-through type spool all adopt the plane rotation sealing means, and ceramic plate adopts uniform fan shaped borehole structure more, thereby its flow is decided by to form the area size of the fan shaped borehole of the stator of ceramics and moving plate.When certain, fan-shaped hole count of ceramics diameter and one timing of its central angle, the best method that strengthens the fan shaped borehole area for the raising flow is the width that reduces to fan arc place sealing strip, the edge rings band of round ceramics is narrowed down, but this certainly will influence the sealing reliability of (passing through seal washer) between ceramics and the valve body at fan arc place sealing strip, the result reduces the pressure-resistant seal performance of valve, the total quality unreliability is increased, cause this a pair of contradiction between reliability and the flow to be difficult to for a long time solve.Equally also there is the contradiction between sealing and the switch torque (feel), and owing to also there be can not two-wayly use on the function in structural reason.
The objective of the invention is to overcome above shortcoming, the ceramic seal spool of the optimization type structure of a kind of two ceramics and a porcelain ring is provided, with the wearing and tearing of eliminating non-ceramics parts or under the prerequisite that does not increase the ceramics external diameter, strengthen the fan shaped borehole area as far as possible, improve the maximum discharge of various valves and optimizing structure of the ceramic valve core in high reliability and working life thereof that existing two ceramics and three ceramics are spool.
Another object of the present invention provides the versatility spool of a kind of two ceramics and a porcelain ring so that assembling and maintenance use.
Technological scheme of the present invention is the improvement to the porcelain spool of existing two ceramics or three ceramics, is about to the porcelain spool of two ceramics.Increase by a porcelain ring again, and three ceramics are replaced a stator of moving plate one side with the porcelain ring, being about to ceramic valve core, all to add the form of optimizing structure of a porcelain ring with two ceramics of stator and moving plate alternative, and this porcelain ring is specifically designed as the structure that endoporus is coniform hole; And then consider good airproof performance again and improve flow that also one side, plane that its stator and packing ring are fitted is designed to a concave surface polymorphic structure body, and the example of this multiple valve of optimizing structure is showed its extensive use as several specific embodiments.
Obviously the present invention both had been different from the porcelain spool that has only two ceramics, different with three ceramics porcelain spools again, it has solved the difficult problem of the last seal leakage of the valve that ceramic valve core forms effectively, greatly improved the working life of whole valve, and ingenious reasonably overcome between flow and the reliability and sealing and switch torque between contradiction, and make that the straight-through valve of being formed is two-way all can be used.
