Description

Technical Field

[0001] The utility model relates to the technical field of waterway control valves, in particular to a bathroom water outlet valve that is resistant to freezing and cracking. Background Art

[0002] In the cold winter in the north, due to the low temperature, the water inside the main body will expand due to freezing, causing the volume to increase. After the water in the main water channel freezes, it will squeeze outward, causing the joints, valve core, main body, etc. to be squeezed and broken, resulting in water leakage, making the product unable to be used normally. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a freeze-proof bathroom water outlet valve. An explosion-proof valve with a pressure relief hole is installed in the water line. When ice forms, the water pressure in the pipeline pushes the valve core of the explosion-proof valve to move, allowing some water in the pipeline to flow out of the pressure relief hole, achieving the effect of reducing pressure and relieving pressure. When the water pressure in the pipeline recovers, a spring resets the valve core, effectively protecting the water outlet valve.

[0004] According to an embodiment of the present invention, a bathroom water outlet valve that prevents freezing and cracking includes:

[0005] The valve body has a water inlet chamber, a water outlet chamber and a water mixing chamber. The water inlet chamber and the water outlet chamber are both connected to the water mixing chamber. The water inlet chamber is provided with a cold water inlet and a hot water inlet. The water outlet chamber is provided with multiple functional water outlets. A mixing valve is provided in the mixing chamber. The functional water outlet is provided with a functional control valve. The mixing chamber is provided with a mixing valve. An overflow port is provided at one end of the water outlet chamber away from the mixing chamber.

[0006] The explosion-proof valve includes a valve seat and a valve core with a hollow structure. The valve seat is installed on the overflow port and is connected to the water outlet chamber. A pressure relief hole is provided at one end of the valve seat extending to the overflow port. The pressure relief hole is connected to the inner cavity of the valve seat. The valve core is inserted in the inner cavity of the valve seat. Due to the pressure change in the water outlet chamber, the valve core can move back and forth in a straight line in the inner cavity of the valve seat to change the connection state between the pressure relief hole and the water outlet chamber.

[0007] According to the embodiment of the utility model, a bathroom water outlet valve with an anti-freeze cracking function has at least the following beneficial effects: when the temperature drops and ice forms inside the valve body, the water pressure in the water outlet chamber increases due to the ice in the valve body. The water pressure pushes the valve core outward, directly moving it to the water outlet chamber and connecting it to the pressure relief hole. The water in the water outlet chamber flows out of the pressure relief hole, thereby reducing the water pressure in the valve body and preventing the valve body from bursting due to internal ice. When the temperature drops, the ice in the valve body melts, and the pressure drops, the valve core resets to block the overflow port, allowing the water outlet valve to operate normally.

[0008] According to an embodiment of the utility model, a bathroom water outlet valve that is anti-freeze cracking, the valve core includes a main rod body and a ring plate arranged on the main rod body. The ring plate is arranged at one end of the main rod body close to the water outlet chamber. When the main rod body moves, it drives the ring plate to move to change the communication state between the water outlet chamber and the pressure relief hole.

[0009] According to an embodiment of the utility model, a freeze-cracking-proof bathroom water outlet valve is provided, and an annular groove is provided at one end of the main rod body facing the water outlet cavity, and a sealing ring is installed in the annular groove.

[0010] According to an embodiment of the present invention, a freeze-cracking-proof bathroom water outlet valve is provided with an end cover at one end of the valve seat away from the overflow port. The end cover has a through hole, and the end of the valve core can pass through the through hole.

[0011] According to an embodiment of the present invention, a frost-proof bathroom water outlet valve further includes a return spring sleeved on the exterior of the main rod, with one end of the return spring abutting against the ring plate and the other end abutting against the end cap. The return spring is used to automatically return the valve core to its original position after the water pressure within the valve body is restored.

[0012] According to an embodiment of the utility model, a freeze-cracking-proof bathroom water outlet valve is provided with an end cover having an external thread, and an end of the valve seat close to the end cover is provided with an internal thread, and the end cover is threadedly connected to the valve seat.

[0013] According to an embodiment of the present invention, a freeze-crack-proof bathroom water outlet valve is provided, and the end cover is further provided with a limiting nut.

[0014] According to an embodiment of the present invention, a bathroom water outlet valve that is resistant to freezing and cracking has one end of a main rod extending to the outside of the end cover after passing through a through hole, and a socket is provided at the end of the main rod.

[0015] According to an embodiment of the present invention, a bathroom water outlet valve that is resistant to freezing and cracking is provided with a sealing ring between the valve seat and the overflow port.
