The device is ceramic valve assembly, comprising a case, a spring, a seal ring, a ceramic valve core, a rotary valve handle, a clamp spring, a drive plate and a stop block; the case is internally provided with a ceramic valve core, the side of the case is provided with a through hole, the bottom is provided with the seal ring, the spring is sheathed at the periphery of the case, the upper part in the case is provided with the drive plate and the clamp spring, the clamp spring is connected with the hole at the lower end of the rotary handle of tap, and the valve core is controlled to open or close by the handle of tap. The invention has the beneficial effects that technical upgrading and updating can be carried out on the spiral lift tap, the problem of leak through of spiral lift tap can be effectively solved, and the tap is given with brand new usage function and value. The product of the invention is safe, environmentally friendly, water-saving and material-saving and has long service life and wide application prospect.

Description

【Technical field】 [0001] The invention relates to the technical field of tap water supply equipment, and relates to a method and device for preventing dripping of a spiral lift type faucet. The ceramic sheet sealing valve seat assembly (hereinafter referred to as "ceramic valve assembly") with a ceramic valve core is used to replace the original washer and washer seat to prevent dripping of the spiral lift faucet. 【Background technique】 [0002] The screw-type faucet has been used for nearly two centuries, because of its simple structure and convenient use, it has been widely used all over the world. For the washer in the faucet is easy to wear and tear, causing the problem of faucet dripping, the method of replacing the washer has been adopted for a long time to deal with it. [0003] Since the 1970s, with the birth of precision industrial ceramic technology, faucets sealed with ceramic valve discs have been born. The faucet sealed with ceramic valve plate has good sealin...

[0004] Although faucets sealed with ceramic discs have many advantages and are widely used in new buildings, there are many types of screw-type faucets (of various brands, products, sizes and models, some of which are used) that are already in use. Or international brand-name products) buildings, how to solve the problem of faucet washer wear? If you want to replace the faucet with ceramic valve disc sealing, the project is huge and the cost is high, and many spiral faucets have high use value, including historical and cultural value, it is a pity to discard it; but if you do not change it, These faucets always have the problem of dripping, so we can only use the method that has hardly changed in the past 200 years-regularly replace the washers

[0005] In this regard, some foreign manufacturers have developed some ceramic spool cocks that can replace the original spiral cocks for some of the spiral lift faucets they have produced in the past or now. However, because the old spiral lift faucets have been used for too long, There are too many varieties and specifications of the original screw plugs, and it is impossible to design and develop replacement products for all types of screw plugs. Not only is it difficult to have economic benefits in production, but it is also quite difficult in replacement and maintenance.

In addition, the existing replacement products are replaced as a whole. The replacement parts are not only complex in structure, but also large in size and use a lot of metal materials, so the cost is very high. The market price is equivalent to the price of the entire faucet, so it is difficult to promote

Due to various reasons mentioned above and not yet involved, the dripping problems of various spiral-type faucets in use still exist and have not been well resolved.
