Embodiment 1

[0052] like Figures 1 to 7 The shown outlet faucet for RO machine pressure relief includes a main body 3, a water outlet pipe 1 and a water inlet pipe 5. The water inlet pipe 5 is connected to the pressure water storage tank in the RO machine, and transports the water in the water storage tank to the water outlet faucet. Position, by twisting the valve core of the water outlet, the purified water after filtering can flow out from the water outlet pipe 1. Since there are many types of valve cores and various opening and closing methods, the valve core is not required in the present invention. Do limited.

[0053] The bottom of the water inlet pipe 5 is provided with a special quick joint 51 in the RO machine, through which the water outlet tap can be quickly connected to the pressure water storage tank.

[0054] The drain pipe 43 is connected with the water outlet pipe 1, and can discharge the water discharged due to high pressure from the water outlet pipe. The discharged wate...

Embodiment 2

[0070] like Figure 8 to Figure 11 The shown outlet faucet for RO machine pressure relief includes two water inlet pipes 5 , two valve cores 2 and one water outlet pipe 1 .

[0071] There are some RO machines on the market with multiple functions, which can treat the purified water output from the pressure water storage tank through the post-installed activated carbon filter, and then perform various treatment methods such as weak alkalinization, oxygen enrichment, and hydrogen enrichment. Therefore, a There may be two or more pressure water storage tanks in the RO machine, and the two pressure water storage tanks are respectively connected to the water outlet pipe 1 .

[0072] Therefore, two elastic pressure relief valves 4 are required to control the water pressure in two pressure water storage tanks on a water outlet tap, and the number of pressure water storage tanks determines the number of elastic pressure relief valves 4 required.

[0073] like Figure 9 As shown, the...

Embodiment 3

[0078] like Figure 12 to Figure 16 , it is used for the pressure relief faucet of the RO machine with manual reset, and this embodiment 3 can realize all the functions mentioned in the embodiment 1.

[0079] The difference is: when the water pressure in the pressure water storage tank is too high, the valve cover 41 will pop out of the installation cavity, and the elastic pressure relief valve 4 will be fully opened, and the elastic pressure relief valve 4 will always be in pressure relief before the valve cover 41 is reset. state, lower the water pressure in the pressure storage tank.

[0080] The inner surface of the valve cover 41 in the present embodiment 3 is provided with a sliding pipe wall 413, and the main body 3 is provided with a sliding pipe groove 30 for the telescopic sliding of the sliding pipe wall 413. The limit structure for the bonnet 41 to come out, the limit structure includes a limit convex ring 414 and a limit stop ring 300, the limit stop ring 414 is ...

Abstract

The invention discloses a faucet. The faucet comprises a main body, a water outlet pipe and a water inlet pipe, wherein the main body is connected with the water outlet pipe and the water inlet pipe; a water drainage pipeline, a water inlet pipeline connected with the water inlet pipe, and an elastic pressure release valve used for controlling open-on and cut-off of the water inlet pipeline and the water drainage pipeline are arranged in the main body; the elastic pressure release valve comprises a sealing element, a valve cavity, and a return element for returning the sealing element; the valve cavity and the outer wall of the main body are arranged in a sealing manner; the sealing element carries out reciprocating motion or rotation in the valve body through the return element; the sealing element opens on and cuts off communication between the water inlet pipeline and the water drainage pipeline; and the water drainage pipeline is connected into the water outlet pipe. Firstly, a water pressure in a water storage bucket can be relieved, and the pressure is reduced to avoid burst of the water storage bucket; and secondly, a user can be effectively reminded of overpressure of the water storage bucket to timely maintain and replace.

Description

technical field [0001] The invention relates to a water flow switch, which is a water faucet. Background technique [0002] RO machine is a kind of reverse osmosis filtration method that is popular in the world, pressurizes raw water, uses physical principles to filter, and then does not add any compounds to produce pure water machines that can be directly consumed by humans (also known as terminal water purification equipment). The RO machine is divided into household type, experimental type and pure water engineering machine, and the RO machine designed in the present invention is a household type water purification equipment. [0003] like Figure 18 As shown, the domestic RO machines on the market, from the water inlet to the water outlet, include: [0004] ①The first three stages of filtration: PP cotton fiber filter element-granular activated carbon filter element-sintered activated carbon filter element to remove suspended solids, discoloration, chlorine, organic ch...
