Problems solved by technology

However, the existing mixing valve technology is greatly affected by the water pressure of cold and hot water. For example, when the cold water uses civil tap water, the water pressure is generally higher, while the hot water pressure at the other end is generally lower, especially when using solar energy. When using a water heater, the water pressure is only the difference between the installation position of the solar water heater and the user's shower; when the water pressure difference between the two water inlet ends of the mixing valve is too large, cold water will refill the hot water, causing the entire system to be in disorder , or the opposite, hot water not only flows to cold water, but high temperature hot water can also scald people

Embodiment Construction

[0009] The attached drawing is a cross-sectional view of an embodiment of the present invention. The device is composed of a mixing valve part and two water inlet pressure limiting valves. In the valve body (22), a cylindrical annular water jacket (17), (21) is installed, In the mixing chamber of the annular water jacket, there are upper and lower pistons (19) and (3) with sealing rings. Below the lower piston (3) and above the mixing water outlet, there are a temperature bulb device (2) with mechanical thrust , There is a reset pressure spring (1) under the temperature bulb device (2), the temperature bulb device (2) drives the pistons (19) and (3) to move up and down through the temperature control displacement member (20); the annular water jacket (17) The inner cavity of (21) is provided with water inlet holes for cold and hot water. Corresponding to the cold and hot water inlet holes, there are water inlet ring grooves for hot and cold water on the inner wall of the valve b...

Abstract

The invention relates to a mixed water valve for automatically limiting flow, which belongs to the technical field of the manufacture of water heating equipment. The mixed water valve is characterizedin that a cylindrical annular upper water jacket and a cylindrical annular lower water jacket are arranged in a valve body; a mixed water cavity of the annular water jackets is provided with an upperpiston and a lower piston with a seal ring; the lower side of the lower piston is provided with a thermal bulb device with mechanical thrust; the lower side of the thermal bulb device is provided with a return compression spring; the thermal bulb device can drive the pistons to move up and down through a temperature controlled displacement part; and a water inlet pressure limiting valve is arranged in a hot and cold water inlet of the mixed water valve, and comprises a balanced cover, a balanced sliding sleeve, a balanced piston rod and a balanced compression spring.

Description

Technical field [0001] A water mixing valve with automatic flow restriction, suitable for cold and hot water supply systems in buildings, belongs to. The technical field of plumbing equipment manufacturing. technical background [0002] With the gradual improvement of people's living standards, many residential communities have already used hot water, so cold and hot water mixing valve technology has also been used more and more. However, the existing mixing valve technology is greatly affected by the water pressure of the cold and hot water inlet. For example, when the cold water is used for civil tap water, the water pressure is generally higher, and the hot water pressure at the other end is generally lower, especially when solar energy is used. In the case of water heaters, the water pressure is only the difference between the installation position of the solar water heater and the user's shower; when the water pressure difference between the two inlets of the mixing valve i...
