Problems solved by technology

[0002] There are three-way valves consisting of two sets of spools and seals, an enclosed valve body and a toggle device. For example, the three-way locking valves used in HVAC equipment are of the spiral lift type or cock type, which are not wear-resistant. damage, low life, easy leakage, inaccurate flow regulation, if it is a metal seal, it requires high manufacturing precision of the valve body, and precision grinding is often required on the sealing surface

Abstract

A sealed three-way ceramic valve is composed of valve core, valve body, sealer and driver, and features that the left and right valve core sets with uniformly distributed 2 or more through hole sare axially or perpendicularly installed in the cavity of valve body, and the drive rings in the drivers in the valve core sets are used to realize linkage. Its advantages include high antiwear, anticorrosion and sealing performance, long service life and correct flow regulation.

Description

Technical field: [0001] The invention relates to a ceramic sealing three-way valve. technical background: [0002] There are three-way valves consisting of two sets of spools and seals, an enclosed valve body and a toggle device. For example, the three-way locking valves used in HVAC equipment are of the spiral lift type or cock type, which are not wear-resistant. Damage, low life, easy leakage, inaccurate flow regulation, if it is a metal seal, it requires high manufacturing precision of the valve body, and precision grinding is often required on the sealing surface. [0003] The object of the present invention is to overcome the above disadvantages and provide a ceramic sealing three-way valve suitable for industrial and civilian use, which is wear-resistant, corrosion-resistant, good in sealing, long in life and accurate in flow regulation. Invention content: [0004] The present invention is to install two groups of valve cores on the left and right sides, which are c...
