Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of the existing pressure-bearing water tanks for water heaters that are easily damaged or even broken due to too high pressure, and the heat exchange efficiency is low, and provide a multifunctional safety valve with simple structure, convenient installation, and low heat transfer efficiency. The pressurized water tank has a long service life, realizes secondary safety protection, enhances safety protection functions, and prevents the water tank from being easily damaged or even broken due to excessive pressure.

Embodiment Construction

[0017] Such as figure 1 , figure 2 As shown, the multifunctional safety valve is mainly composed of a ball valve body 1, a ball valve core 3, and a ball valve control device 2. The ball valve body 1 is provided with a low-pressure one-way safety valve and a high-pressure one-way safety valve in parallel. The low-pressure one-way safety valve and A communication hole 12 is provided between the high-pressure one-way safety valves, an overflow hole 6 is provided on the low-pressure one-way safety valve, a joint nut 17 is connected to the ball valve body, and an overflow channel 5 is opened on the ball valve core 3 .

[0018] The beneficial effects of the present invention are: adopting the multifunctional safety valve with the above structure, when hot water is used, the ball valve control device 2 is operated to make the ball valve core 3 in an open state, and tap water enters the water tank through the water hole 4 of the ball valve core 3, so as to To make up for the consump...

Abstract

The invention discloses a multifunctional safety valve. The multifunctional safety valve is mainly composed of a ball valve body, a ball valve element and a ball valve controlling device. The multifunctional safety valve is characterized in that a low-pressure one-way safety valve body and a high-pressure one-way safety valve body are arranged on the ball valve body side by side, a communication hole is arranged between the low-pressure one-way safety valve body and the high-pressure one-way safety valve body, an overflowing hole is formed in the low-pressure one-way safety valve body, an articulated nut is further connected to the ball valve body, and an overflowing channel is formed in the ball valve element. The multifunctional safety valve has the advantages that the structure is simple, installation is convenient, the service life of a pressure-bearing water tank is long, two-level safety protection is achieved, the safety protection function is enhanced, and the phenomenon that the water tank is damaged or even cracked easily due to over-high pressure is prevented.

Description

Technical field [0001] The invention relates to a solar heating device, in particular to a multifunctional safety valve. Background technique [0002] At present, with the continuous improvement of people's living standards and the rapid upgrading of water heater products, various electric water heaters, split solar water heaters, and pressure-bearing water heaters are gradually being popularized and used. Their water tanks are generally made into pressure-bearing types to ensure water supply. There is a suitable pressure from time to time, which can effectively meet the pressure requirements, and is especially suitable for high-rise buildings where ordinary solar water heaters cannot be installed on the roof. The known pressurized water tank for water heaters, when using water normally, opens the tap water inlet valve to maintain a certain water supply pressure, but when the water is stopped, in order to prevent the hot water from flowing back in the water tank or the water...
