Description

Precision ceramic control valve structure

This creation is about a "precision ceramic control valve structure", especially a precision ceramic control valve that can be used to change the effluent state of the faucet without the use of a pull head.

Press, the use of the faucet usually provides the front water and the shower head. When the two different water outlets are used on the same faucet, the pull of the pull head is used to enable the water source to be switched, that is, when the faucet is opened, The water flow usually flows directly from the front end of the faucet into the lower container (such as a washbasin or a bathtub). When the water is to be changed, the upper pull-up head is used to close the flow path of the front water outlet through the pulling head, so that the water flow can be changed upwards. The water pipe is sprayed through the shower head, and the pulling head is supported by the water pressure without falling down until the water source is closed, so that the water pressure inside the faucet is reduced to less than the weight of the pulling head, the pulling head will be Take the initiative to fall.

However, because the conventional faucet is used, there will be a pulling head extending above the faucet. In addition to causing a sudden bulging, the additional pulling head will greatly damage the overall beauty of the faucet, and further, the upwardly extending Pulling the head is easy to be touched, and the state is changed without warning.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional faucets is actually the goal of the relevant industry to develop and research. The creator has in this view, thinking and creating ideas, and designing with years of experience. After many discussions and trials of sample tests, and many revisions and improvements, this work was launched.

Because of the necessity of water control, the conventional faucet will have a pulling head extending above the faucet. The pulling head is easily misunderstood and will appear abrupt. This is the technical problem to be solved.
