Self-operated type constant-temperature water mixing valve for floor heating

Abstract

The invention discloses a self-operated type constant-temperature water mixing valve for floor heating, comprising a valve body and a valve rod. The upper end of the valve rod is connected with a hand wheel, the lower end of the valve rod is connected with a valve bonnet on which a dial is arranged, the valve bonnet is connected with the valve body and the lower end of a lifting hexagon, a hexagon at the upper end of the lifting hexagon is in guiding fit with the valve rod, a spring b and a baffle plate are arranged in an inner cavity of the lifting hexagon, and the lower end of the baffle plate is fixedly connected with the lifting hexagon; and a core cylinder is arranged in the valve body and is connected with a connecting sleeve in which a thimble is arranged, the lower end of the connecting sleeve is connected with a thermosensitive device, the lower end of the thermosensitive device is provided with a spring a, the lower end of the spring a is provided with a spring base installed at the lower end in the valve body, one side of the valve body is provided with a cold water inlet, the other side is provided with a hot water inlet, and the cold water inlet and the hot water inlet are both provided with check cores. The invention has the advantages of good accuracy of temperature control, stable performance, convenient use, good constant-temperature water mixing function.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a self-operated thermostatic water mixing valve for floor heating. Background technique [0002] At present, the hot water supply system has been quite popular, and the application of hot water supply system equipment can be seen everywhere. The outstanding features such as long service life have attracted widespread attention from consumers. Manufacturers have not only repeatedly studied and improved the core structure (control valve) of the floor heating system according to the existing technology, and various structures have emerged in endlessly, but the vast majority of valves All of them are directly assembled by using common valve products with special performance on the market and components such as distributors, water collectors, and pipes. In the stage, there are great defects in the practicality and applicability of the product. Contents of the invention [0003] The...
