Anti-leakage anti-overpressure mixed water thermostatic valve

Abstract

The invention discloses an electric leakage-preventing and overpressure-preventing water mixing constant temperature valve which comprises a water mixing valve and an external pressure release valve, wherein the water mixing valve communicates with a cold water channel and a hot water channel; the water inlet of the cold water channel communicates with a tap water pipeline through a check valve; connecting pieces that are connected to the water inlet of an electric hot water tank and the water outlet of the electric hot water tank are separately arranged at the upper end of the cold water channel and the upper end of the hot water channel; each connecting piece comprises an outer-hexagonal nut for connecting the water inlet of the electric hot water tank, a T-shaped connector which is connected onto the outer-hexagonal nut and is connected to the cold water channel, and an insulating jacket which covers the outer-hexagonal nut. According to the electric leakage-preventing and overpressure-preventing water mixing constant temperature valve disclosed by the invention, the insulating jackets are arranged on outside the corresponding outer-hexagonal nuts and the corresponding T-shaped connectors in a sleeving manner, so that a user is not in contact with the conductive metal parts, and the electric leakage-preventing and overpressure-preventing water mixing constant temperature valve has a good protective performance.

Description

technical field [0001] The invention relates to a water valve, in particular to a leakage-proof and overpressure-proof mixed water thermostatic valve. Background technique [0002] The water mixing valve is an important part of the water heater. It can not only introduce cold water into the water heater, but also adjust the temperature of the water outlet, making the water temperature more suitable for people to use. However, the existing water mixing valves are generally made of metal, or a layer of metal is plated on the surface of the pipe. Not only the manufacturing cost is high, but also once the water heater has a problem and causes an electric leakage, it will cause people to be in danger of electric shock. In recent years, incidents of electric water heaters leaking and hurting people have occurred repeatedly in various parts of our country, exposing the urgency of how electric water heaters can prevent hidden dangers in consumers' household electricity use environme...
