A kind of water supply valve with double-layer intercommunication of ceramic closure element

Abstract

The invention discloses a double-layer intercommunicating water supply valve of a ceramic closing element, and relates to the technical field of ceramic valves. The double-layer communicating water supply valve of the ceramic closing element solves the problems that an existing valve can be maintained only by cutting off water, an additional water cutting step is troublesome, the normal productiontime is occupied, the production efficiency is influenced, and the practicability is poor. The double-layer intercommunicating water supply valve of the ceramic closing element comprises a valve body, a water pipeline, a square sleeve rod and vertical supporting and inserting rods, wherein the valve body comprises a valve element sleeve, a supporting frame and a hand wheel, the valve body is of arectangular structure, a penetrating shaft hole is formed in the valve body, the valve element sleeve is welded and supported at the top end of the penetrating shaft hole, a circular cover plate is locked and blocked at the bottom of each of the valve element sleeve and the penetrating shaft hole, a supporting frame is welded to the top end of the valve body in a supporting mode, and the hand wheel is installed in the top middle position of a supporting rod of the supporting frame in a rotating-inserting mode. According to the double-layer intercommunicating water supply valve of the ceramicclosing element, two ceramic valve elements can be inserted, connected, abutted and positioned together through the two vertical supporting and inserting rods, and the two ceramic valve elements are prevented from being loosened and separated.

Description

technical field [0001] The invention relates to the technical field of ceramic valves, in particular to a double-layer intercommunicating water supply valve with ceramic closing elements. Background technique [0002] In terms of production technology and process, metal valves are more mature among household valves. Stainless steel valves and copper valves are more common in the market. There are also cast iron valves in slightly low-end products, but metal valves have quite a lot of defects. Metal valves During long-term use, problems such as corrosion, rust, and plating peeling are extremely prone to occur. Heavy metals such as lead and tin in the alloy used to manufacture metal valves will gradually penetrate into the water and cause pollution. Directly, although plastic valves can pass through Injection molding is very precise in size, but the plastic has the problem of easy aging, and the use of time is compensated; and the characteristics of the injection molding proce...

Problems solved by technology

[0005] The purpose of the present invention is to provide a water supply valve with double-layer intercommunication of ceramic closing elements to solve the problem that most of the valve cores proposed in the above-mentioned background technology are built-in, and the process of dismantling and taking out is cumbersome and inconvenient. The additional water stop steps are cumbersome and take up normal production time, affecting production efficiency and poor practicability
