Problems solved by technology

According to the requirements of the national standard GB18145-2104 related to the ceramic sealing faucet, the metal pollutants of the faucet are precipitated - the lead content is ≤5ug / L. In order to meet this requirement, if the material is made of plastic, the lead content precipitation can meet the standard, and the cost is also low. , but the plastic thread is easy to slip and break, and the compression resistance is relatively poor; stainless steel is used, because stainless steel itself does not contain lead, and the lead content can reach the standard, but stainless steel is difficult to process and the cost is relatively high; copper is used, currently on the market It is more mainstream and easier to process, but to achieve the standard of lead content precipitation, it is necessary to use lead-free copper material, and the cost is relatively high

Embodiment Construction

[0018] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] refer to figure 1 , the first embodiment provides a ceramic quick-opening valve core, including a housing and a valve core rod 1 installed in the housing, the housing includes a plastic valve core body 2, a metal valve core sleeve with a connecting portion 31 3. The metal valve core cover 3 is sleeved on the outside of the plastic valve core body 2, and the metal valve core cover 3 and the plastic valve core body 2 are integrally formed by injection molding. The metal valve core sleeve 3 is in interference fit with the plastic valve core body 2 . The part where the metal valve core sleeve 3 is attached to the plastic valve core body 2 is an inner hexagonal surface.

[0020] The part where the metal valve core sleeve and the plastic valve core body are bonded can also be other non-circular surfaces (such as square, rhombus, triangle, etc.) or...

Abstract

The invention relates to a ceramic quick opening valve element. The ceramic quick opening valve element comprises a shell and a valve element rod arranged in the shell. The shell comprises a plastic valve element body, and a metal valve element sleeve with a connecting part. The plastic valve element body is sleeved with the metal valve element sleeve, and the metal valve element sleeve and the plastic valve element body are in interference fit. The invention further relates to a production process of the ceramic quick opening valve element. During production, the metal valve element sleeve is formed in advance, then the metal valve element sleeve is put in a mold, powering-on and heating are carried out, then melted plastic is injected, and the ceramic quick opening valve element is formed after solidification and cooling are completed.

Description

technical field [0001] The invention relates to a ceramic quick-opening valve core and a production process thereof. Background technique [0002] A spool is usually installed in the existing faucet, and the structure of the spool is usually assembled by a housing, a valve stem, a moving valve plate, a static valve plate and a base in sequence. [0003] Chinese patent number: CN201310244830.4 discloses a faucet spool, including a spool body, a rotating rod installed in the spool body from top to bottom, a moving valve piece and a fixed valve piece, the moving valve piece is fixed At the bottom of the rotating rod, the bottom of the valve core body is provided with a water-sealing rubber ring, the side wall of the valve core body is provided with a mounting thread and a water outlet, and an O-ring is provided above the mounting thread. The position of the water outlet on the valve core remains unchanged, the axial height of the installation thread part remains unchanged, the...
