Multifunctional protection ball valve for washing machine

Abstract

The invention discloses a multifunctional protection ball valve for a washing machine. The multifunctional protection ball valve comprises a valve body (1), a ball valve core (2), a valve rod (21), a knob (22), a check core (3), a filter net (4), a pressure relief ball (5) and a plug cover (6). The device formed by components is adopted, the valve body is a copper casing in a four-way shape, a water inlet, a valve core chamber and a net cavity chamber are arranged in the valve body from the left side to the right side, a valve rod seat is arranged on the valve core cavity, a water outlet is formed under the net cavity chamber, the ball valve core is positioned in the valve core chamber, the valve rod is positioned in the valve rod seat, the ball valve core is connected with the knob positioned outside the valve body through the valve rod, the check core is arranged in the water inlet, the tubular filter net is arranged in the net cavity chamber, a pressure relief ball is positioned at the right side of the filter net, and the plug cover is sealed and plugged at the right end of the net cavity chamber. Through the technical scheme, the washing machine can be connected with a tap water pipeline, and the goals of leaking water flushing disengagement avoidance, easy sand plugging clearing, reverse flowing hidden danger elimination and water hammer danger relief can be reached.

Description

technical field [0001] The invention relates to a ball valve, in particular to a multifunctional protective ball valve for washing machines used for connecting the water inlet of the washing machine with a tap water pipeline. Background technique [0002] The basic forms of washing machines are single-tub, double-tub, fully automatic, pulsator-type, and drum-type; the connection between the washing machine and the tap water pipeline, for the single-tub and double-tub washing machines, use a non-pressure hose to directly connect with the tap water tap; A fully automatic pulsator type and drum type washing machine is connected with a water tap by a pressure-bearing hose connector. [0003] Along with the gradual urbanization and high-rise building of folk houses, the following problems have occurred in the connection of the prior art washing machine and the tap water pipeline: [0004] 1) The increase of tap water pressure causes water leakage or even flushing at the connecti...

AI Technical Summary

Problems solved by technology

[0004] 1) The increase of tap water pressure causes water leakage or even flushing at the connection between the washing machine and the faucet, that is, the problem of water leakage and flushing;

[0005] 2) The expansion of the city and the extension of the water pipe network lead to an increase in the scale of the water pipe, and the scale that falls off forms scale sand that flows with the tap water. The scale sand will block the filter screen of the washing machine water inlet, resulting in prolonged water filling time of the washing machine. In severe cases, the coil of the water inlet solenoid valve of the fully automatic washing machine will be overheated and burned, that is, the problem of sand blockage;

[0006] 3) Due to the rinsing of the single-tub washing machine, it must be manually rinsed in another rinsing tank or water basin, and some people are used to immersing the hose connected to the faucet in the rinsing tank for long-term continuous rinsing; For high-rise single-tub washing machine users, when the water is cut off in the high-rise building, the sewage in the rinse tank will flow back into the tap water pipe due to the siphon phenomenon, causing the siphon backflow pollution event of the tap water pipe network, that is, the backflow problem;

[0007] 4) The popularization of household fast valves and the quick switch of the washing machine water inlet solenoid valve will generate impact water pressure called water hammer effect in the indoor tap water pipeline. The water hammer effect will cause the expansion of the washing machine's connection pressure hose to fatigue, Reduced service life, i.e. water hammer problem

[0008] Therefore, the prior art has the problems and deficiencies of water leakage, sand blocking, backflow, and water hammer damage.
