Problems solved by technology

[0004] However, the above-mentioned quick-opening spool has some shortcomings: first, the spool needs to position the valve stem, ceramic moving piece, ceramic static piece, etc., so the processing requirements for the spool are relatively high, and the processing is relatively difficult. It is troublesome and the cost is relatively high; the sealing gaskets are generally made of soft materials, such as rubber, etc., and are embedded in the lower end of the valve core, so it is easy to make the sealing gaskets become dirty during disassembly and turnover. Loose, resulting in a gap between the ceramic static piece and the ceramic moving piece, affecting normal use, and also easily affecting the sealing effect

Abstract

The invention provides a quick-opening valve core which belongs to the technical field of machinery, and solves the problems that an existing quick-opening valve core is high in processing requirement and poor in sealing effect. The quick-opening valve core comprises a valve core sleeve which is internally provided with a valve rod and a quick-opening core plate; the inner end of the valve rod is connected with the quick-opening core plate; the outer end of the valve rod extends out of the valve core sleeve and is connected with a hand wheel; the valve core sleeve comprises a sleeve body and a valve rod seat connected to the top of the sleeve body; the quick-opening core plate is arranged in the sleeve body; the valve rod is fixed on the valve rod seat; and the inner end of the valve rod extends into the sleeve body. The quick-opening valve core has the advantages of being convenient to process, good in sealing effect, long in service life and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a quick-open valve core. Background technique [0002] The quick-opening spool is the most common spool in the triangle valve. It is generally composed of a spool sleeve, a valve stem and a ceramic valve piece. The valve stem is placed in the spool sleeve. The ceramic valve piece includes a ceramic moving piece and a ceramic static piece. One end of the valve stem extends out of the valve core sleeve and connects with the handle, the other end of the valve stem connects with the moving ceramic piece, and the static ceramic piece is provided with a through hole communicating with the water outlet end and the water inlet end of the valve body. Drive the valve stem and the moving ceramic piece connected with the valve stem to rotate, and control the opening or closing of the through hole on the static ceramic piece, so as to realize the opening or closing of the valve. [0003] For ...
