Embodiment Construction
[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0016] see figure 1 , the embodiment of the present invention includes:
[0017] A safe anti-scalding physical valve for high-temperature liquid self-cutoff, comprising: a valve housing 1 and a valve core 2, the valve core 2 is arranged inside the valve housing 1, and the top of the valve core 2 is provided with an extension To the operating rod 3 on the top of the valve housing 1, the switch rotation operation is flexible.
[0018] A water passage hole 22 is horizontally arranged in the valve core body 2, a blind ...

The invention discloses a safety anti-scald physical valve capable of automatically cutting off high-temperature liquid. The safety anti-scald physical valve comprises a valve shell and a valve core, wherein a water passing hole is transversely formed in the valve core, a blind hole extending upwards is formed in the bottom of the valve core, a lifting plate is arranged in the blind hole, a water blocking plate perpendicularly extending into the water passing hole is arranged on the lifting plate, an elastic air bag is arranged below the lifting plate, and temperature sensing gas is arranged in the elastic air bag. Through the mode, the safety anti-scald physical valve capable of automatically cutting off high-temperature liquid has the advantages that the heat of fluid is transferred to the elastic air bag by the water blocking plate through the lifting plate; when the temperature of the fluid in the water passing hole is higher than a limit value, the temperature sensing gas in the elastic air bag expands due to heat, the lifting plate is jacked up, the top of the water blocking plate extends into a clamping groove, the blocking of the water passing hole is finished, and the supply of the fluid is cut off; and in this way, a scald problem is avoided, and using safety is improved.
Description
technical field [0001] The invention relates to the field of valves, in particular to a safe anti-scalding physical valve for high-temperature liquid self-cutoff. Background technique [0002] Ball valve is a kind of valve, widely used. The main features of the ball valve are its compact structure, high reliability, easy operation and maintenance, suitable for general working media such as water, solvent and natural gas, and also suitable for a variety of media with harsh working conditions, suitable for use as an on-off valve or a shut-off valve . [0003] Various valves are not sensitive to temperature. Therefore, when the temperature of the liquid in the pipeline changes, especially when the temperature rises, it is easy to cause burns during use, and it cannot be cut off when the liquid temperature is too high. It needs to be improved. . Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a safe anti-scal...
