Problems solved by technology

[0002] In the prior art, when the pressurized water delivery pipe (especially the domestic water inlet pipe) is used to discharge water at the end of the water outlet, the following problems are often caused by the large pressure difference between the water supply and the water discharge: 1) The water flow rate is large, and it is easy to splash and Cause waste; 2) The safety is not good enough; 3) It is difficult to guarantee the water demand of small water volume and low flow rate

Embodiment 1

[0044] A multi-stage decompression and water-saving valve; refer to figure 1 ; It is mainly composed of the following structures: float 1, water inlet valve seat, water saving valve body 16; wherein:

[0045] The water-saving valve body 16 is a structure with a cavity for water storage inside, and an opening is provided at the lower part; specifically, there are two openings: a water inlet and a water outlet;

[0046] The float 1 is arranged on the upper part of the inner cavity of the water saving valve body 16;

[0047] The water inlet valve seat is specifically composed of the water inlet valve upper seat 2, the water inlet valve lower seat 14 and the water inlet valve core seat 3, wherein: the water inlet valve upper seat 2 and the water inlet valve lower seat 14 are arranged in a fixed connection with each other In the lower part of the inner cavity of the water saving valve body 16, the upper seat 2 of the water inlet valve and the lower seat 14 of the water inlet valve...

Embodiment 2

[0076] The content of this embodiment is basically the same as that of Embodiment 1 (refer to figure 2 ), the main differences are:

[0077] 1) The multi-stage decompression and water-saving valve is provided with a structure for controlling the height position of the water inlet valve core seat 3 in the vertical direction according to the position of the float 1, which meets the following requirements:

[0078] The multi-stage decompression and water-saving valve is provided with a structure for controlling the height position of the water inlet valve core seat 3 in the vertical direction according to the position of the float 1, which meets the following requirements: The connecting rod 21 fixedly connected with the valve core seat 3 of the water inlet valve and the float 1 is also arranged in the water-saving valve of the stage decompression. Simultaneously perform up and down movements.

[0079] 2) In the multi-stage decompression and water-saving valve, the inner cavit...

Embodiment 3

[0091] This embodiment is basically the same as embodiment 1 or 2 (do not provide figure, but can refer to figure 1 Or 2 corresponds to understanding), the difference mainly lies in:

[0092] 1) The water inlet valve inner chamber 20 inside the water inlet valve upper seat 2 and the water inlet valve lower seat 14 communicates with the inner cavity of the water saving valve body 16 through one of the following structures or a combination thereof: a hole with a circular cross section , flow channels and slits with non-circular cross-sections;

[0093] 2) When this embodiment is based on Embodiment 1, the multi-stage decompression and water-saving valve also meets the following requirements: the multi-stage decompression and water-saving valve is provided with a control valve that meets the following requirements According to the position of the float 1, the structure of adjusting the height position of the valve core seat 3 of the water inlet valve in the vertical direction is...

Abstract

A multi-stage pressure-reduction water valve consists of a floater (1), a water inlet valve seat and a water saving valve body (16), wherein the water saving valve body (16) is in a structure provided with a water storage cavity inside and an opening on the lower portion, the floater (1) is disposed on the upper portion of the cavity inside the water saving valve body (16), and the water inlet valve seat is specifically composed of an upper water inlet valve seat (2), a lower water inlet valve seat (14) and a water inlet valve spool seat (3). The upper water inlet valve seat (2) and the lower water inlet valve seat (14) are disposed on the lower portion of the cavity inside the water saving valve body (16) in a fixedly connected manner and jointly enclose the inside to form an inner water inlet valve cavity (20). The multi-stage pressure-reduction water saving valve is reasonable in design, novel in structure, convenient to use and fine in water saving effect, has expectable higher economical value and social value and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the structural design and application technical field of a pressure reducing valve on a fluid flow channel, and in particular provides a multi-stage decompression and water-saving valve mainly used in the upstream of the water discharge port at the end of the pressurized water delivery pipe (for example: residential water inlet pipe) line end. valve. Background technique [0002] In the prior art, when the pressurized water delivery pipe (especially the domestic water inlet pipe) is used to discharge water at the end of the water outlet, the following problems are often caused by the large pressure difference between the water supply and the water discharge: 1) The water flow rate is large, and it is easy to splash and 2) the safety is not good enough; 3) the water demand of small water volume and low flow rate is difficult to be well guaranteed. [0003] People are eager to obtain a multi-stage decompression and water-saving ...
