Problems solved by technology

The throttle in the prior art adopts the method of changing the area of ​​the water hole to realize throttling. For example, the throttle for a water tank inlet valve with the publication number CN201126059Y adopts three water outlet holes on the water outlet round platform on the body. The water inlet platform has two water inlet holes, and an O-shaped rubber ring is added to the cross rib between the water outlet round platform and the water inlet platform. This disclosed restrictor can provide a certain throttling effect, but it cannot meet the needs of more and more people. The corresponding national standard with higher requirements

Embodiment 1

[0032] Figure 1-9 A specific embodiment of the present invention is shown, the labyrinth restrictor 10 of the present invention is built in the water inlet pipeline 17, and water enters in the main liquid chamber 11 of the labyrinth restrictor 10 through the water inlet pipeline 17, by Figure 5 , 6 It can be seen that the main liquid chamber 11 is formed by the inner chamber of the labyrinth restrictor 10, the water flowing through the main liquid chamber 11 enters the second liquid chamber 12 through the water hole group 14, and the water flowing through the second liquid chamber 12 , into the third liquid chamber 13 through the labyrinth channel 15, and finally the water enters the next part of the water inlet pipe from the third liquid chamber 13.

[0033] The second liquid chamber 12 is composed of the outer surface 18 of the labyrinth restrictor 10 with a relatively smaller diameter and the inner surface 171 of the water inlet pipe 17 .

[0034] Several ribs 151 are p...

Abstract

A labyrinth restrictor is generally a cylindrical thin-walled structure, which is integrally formed by injection molding. It includes a main liquid chamber, a second liquid chamber, a third liquid chamber, a set of water holes and a number of labyrinth flow channels, the water in the main liquid chamber enters the second liquid chamber through the water holes, and the water in the second liquid chamber Water enters the third liquid chamber through the labyrinth channel.

Description

technical field [0001] The invention relates to a flow restrictor, in particular to a labyrinth flow restrictor, which is installed in a water inlet pipe for controlling the flow of water in the water inlet pipe, belongs to the field of sanitary ware, and is used for water inlet in toilet water tank fittings. Water valves, showers, faucets and other products that require flow control. Background technique [0002] Many devices in the bathroom industry need to be connected to water supply pipes. As the pressure of the water supply pipe increases, the flow rate at the water outlet of the equipment increases accordingly, which causes damage to the equipment and differences in the flow rate under high pressure. Therefore, It is necessary to use restrictors in sanitary equipment to adjust the uneven flow caused by pressure changes in water supply pipes. The throttle in the prior art adopts the method of changing the area of ​​the water hole to realize throttling. For example, th...
