Embodiment Construction

[0027] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0028] A temperature-controlled spool with interchangeable cold and hot water inlets, refer to image 3 , the main structure includes valve body 1, adjusting rod 2, thermal element 3, ejector rod 4, ejector rod cavity 5 and piston device 6.

[0029] The valve body 1 includes an upper cover 14, a middle cover 15 and a lower cover 16 from top to bottom. The upper cover 14 is threaded to the upper end of the middle cover 15, and the lower cover 16 is threaded to the lower end of the middle cover 15. A mixed water outlet is formed on the lower sleeve 16 , and the middle sleeve 15 is provided with an annular hot water inlet 11 and an annular cold water inlet 12 at different axial heights, and the hot water inlet 11 is located above the cold water inlet 12 .

[0030] The piston device 6 is slidably arranged inside the valve body 1, and is composed of a lower p...

Abstract

The invention discloses a temperature-sensing valve core with a cold water inlet and a hot water inlet which are exchanged. The temperature-sensing valve core comprises a valve body, a thermic element and a piston device, wherein the valve body is provided with the cold water inlet, the hot water inlet and a mixed water outlet; the thermic element is provided with a sensing end and a telescopic end; the piston device is in linkage arrangement with the thermic element and can be glidingly arranged in the valve body; a concave cavity is formed on the piston device; the upper end of the concave cavity and the lower end of the hot water inlet jointly form a hot water passage; the lower end of the concave cavity and the upper end of the cold water inlet jointly form a cold water passage; and the inner side of the concave cavity is provided with a through hole so that cold water and hot water can simultaneously flow in the mixed water outlet. Compared with the prior temperature-sensing valve core, the invention exchanges the positions of the cold water inlet and the hot water inlet so that the cold water inlet is arranged close to the mixed water outlet, thereby avoiding being scalded because of overhigh temperature of a tap and controlling the mixed water outlet to be at a suitable water outlet temperature.

Description

technical field [0001] The invention relates to a water valve, in particular to a temperature-controlled valve core for exchanging cold and hot water inlets. Background technique [0002] The main structure of the temperature control valve core used in the existing thermostatic faucet (especially the thermostatic shower faucet) includes a valve body with a cold water inlet, a hot water inlet and a mixed water outlet, a piston slidably arranged in the valve body, a A thermosensitive element connected with the piston includes a temperature-sensing end and a telescoping end, a push rod and a spring abutting against the heat-sensitive element respectively, and an adjusting rod connected with the ejector rod. The temperature-sensing end of the thermal element is located at the outlet of the mixed water, and the telescopic end is connected to the ejector rod. When the water temperature of the mixed water outlet changes, the temperature-sensing end of the thermal element senses the...
