Abstract

The invention provides a liquid continuous-leakage preventing device, comprising a slider, a casing, a first seal part, a valve spool, a reset spring, a second seal part and a valve body. The left endof the casing is connected with a liquid inlet end while the right end thereof is connected with a liquid outlet end; the valve body is arranged in the middle of the casing and disposed between the liquid inlet end and the liquid outlet end; the valve spool is arranged in the valve body and sleeved with the reset spring, and the left end of the reset spring is abutted against the left end of an inner cavity of the valve body while the right end thereof is abutted against a step on the valve spool; the second seal part is arranged at the left end of the valve spool, and disposed at the left side of the left seal surface of the valve body; the first seal part is arranged at the right end of the valve spool and disposed between the valve spool and the casing and/or valve body; the valve bodyis communicated with a first bypass pipe and the casing on the right side of the valve spool is communicated with a second bypass pipe; a bevel is arranged at the right end of the valve spool, the slider is arranged in the right end of the casing, one end of the slider fits the right end of the valve spool through the bevel. The device can automatically prevent continuous leakage of containers.

Description

technical field [0001] The invention relates to the field of automatic control of liquid pipelines, in particular to a device for preventing continuous leakage of liquid. Background technique [0002] At present, water purifiers on the market generally use PP and other plastics as raw materials for pressure-bearing parts, such as filter bottles, etc. Once the pressure of tap water is too high, the upper limit of the pressure resistance of containers such as ultra-filtration bottles, filter bottles and other containers will burst, and the tap water pipeline will be damaged. If it is connected to containers such as filter bottles, continuous water leakage will occur, causing unnecessary losses. [0003] In the water storage type electric water heater, although the surface of the electric water heater liner (water storage type electric water heater storage container) is treated with enamel, but in the long-term use process, due to the presence of a large number of ions in the t...
