Valve element and water valve

Abstract

The invention provides a valve element and a water valve. The valve element is used for controlling on-off of water flow and water discharge in a shell installed in the water valve, comprises a valveelement shell forming an installing cavity and a water flow control mechanism installed in the installation cavity and is used for controlling the on-off of the water flow and the water discharge; thevalve element shell comprises a first shell and a second shell, wherein the first shell is used for being matched with the water flow control mechanism to form a water flow channel, and the second shell is detachably connected with the inner wall surface of the shell, the end surface of the first shell is detachably connected with the end surface of the second shell, so that an inner cavity of the first shell can communicate with an inner cavity of the second shell, and an installing cavity is formed; and the first shell adopts a non-metal shell, so that heavy metal pollution caused by the first shell to water when the water flows through the water flow channel is avoided. The end face of the first shell is detachably connected with the end face of the second shell, so that the first shell and the second shell can adopt shells of different materials respectively, the first shell adopts the non-metal shell, so that the heavy metal pollution caused by the first shell to the water when the water flows through the water flow channel is avoided.

Description

technical field [0001] The invention relates to the technical field of water valve structures, in particular to a valve core. In addition, the present invention also relates to a water valve comprising the above-mentioned valve core. Background technique [0002] The water valve is commonly known as the faucet, and the water valve controls the size of the water flow through the internal valve core. The existing spool usually includes a spool shell, a valve stem, a moving piece and a static piece. The on-off of the water flow is controlled through the cooperation of the moving piece and the static piece. As an important part of the spool, the spool shell plays a protective role The role of the valve stem, moving piece and static piece. [0003] The material used for the existing spool housing is usually brass, stainless steel or ceramics. In order to improve the convenience of processing, a certain amount of lead was added to the brass. Under the washing of water, lead con...
