Description

Technical fields:

[0001] This utility model pertains to water-saving products and relates to a flow throttling device, particularly one that maintains flow balance when pipeline water pressure changes. Background technology:

[0002] In water passages, flow restrictors are often required. Existing flow restrictors typically consist of pipes and gaskets. Their working principle is to change the flow area by compressing the vertical through-hole with the gasket, thus achieving a flow-limiting effect. Alternatively, they may consist of pipes and sealing rings. Their working principle is to change the flow area of ​​the vertical through-hole by deforming the O-ring seal, thereby achieving the purpose of flow restriction. The disadvantages of these two solutions are: at low pressure, the flow area of ​​the through-hole is also reduced, resulting in flow restriction even at low pressure, making them inconvenient to use. Furthermore, as the pressure increases, the flow area gradually decreases, leading to unstable flow rate changes. Utility model content:

[0003] To address the aforementioned problems in the prior art, the present invention aims to provide a flow throttle that is simple in structure, easy to install and operate, and ensures stable flow during flow restriction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flow throttle includes a body and an elastic gasket that cooperate with each other; wherein the elastic gasket is fitted onto the surface of the body, the body has a water passage hole that connects the water inlet and the water outlet, and a stepped flow passage hole is provided on the side of the body that connects to the water passage hole.

[0006] Furthermore, the stepped flow holes are symmetrically arranged on both sides of the body, including three steps. The bottom step is the first step, and the two sides of the first step extend upward to form the second steps respectively. The two second steps extend upward to form the third steps respectively, and the two sides of the body form grooves that communicate with the water passage holes. The elastic gasket forms a gap with the stepped flow holes to allow water to flow through.

[0007] Furthermore, the three steps are connected by an inclined transition surface.

[0008] Furthermore, a pressure bar is provided on the upper part of the main body, and an elastic pad with an opening in the center is fitted onto the upper surface of the main body through the pressure bar.

[0009] Furthermore, a sealing ring is fitted around the outer edge of the main body.

[0010] Using the above technical solution, this utility model has a simple structure and is easy to install. When installed in the water inlet channel, due to the structure of the side stepped flow hole and the gasket, when the water pressure changes, at low pressure, the elastic gasket is pressed against the first step surface of the stepped flow hole by the water pressure. At this time, the flow area at the step will not restrict the flow. When the pressure continues to increase, the elastic gasket continues to press down and contact the second step surface, or continues to press down, to achieve the effect of restricting the flow and ensuring stable flow changes.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0020] Figures 1-7 The image shown is an embodiment of this utility model.

[0021] like Figures 1-7 A throttle device includes a body 1 and an elastic gasket 2 that cooperate with each other; wherein, the elastic gasket 2 is fitted onto the surface of the body 1, the body 1 is provided with a water passage hole 11 connecting the water inlet end and the water outlet end, and a stepped flow passage hole 12 is provided on the side of the body and communicates with the water passage hole 11.

[0022] In the specific structure, the stepped flow holes 12 are symmetrically arranged on both sides of the body 1, including three steps. The bottom one is the first step 121. The two sides of the first step 121 extend upward to form the second steps 122 respectively. The two second steps 122 extend upward to form the third steps 123 respectively, and the two sides of the body form grooves that communicate with the water passage holes 11. The elastic gasket 2 forms a gap with the stepped flow holes 12 to allow water to flow through.

[0023] Furthermore, the three steps are connected by an inclined transition surface.

[0024] Furthermore, a pressure rod 13 is provided on the upper part of the main body 1, and an elastic gasket 2 with an opening 21 in the center is fitted with the pressure rod 13 and attached to the upper surface of the main body 1. A sealing ring 14 is fitted on the outer edge of the main body 1.

[0025] When installed in the water inlet channel, the structure of the side stepped flow holes and gaskets allows for pressure changes. At low pressure, the elastic gasket is pressed against the first step of the stepped flow holes by the water pressure. At this time, the flow area at the step does not restrict the flow. When the pressure continues to increase, the elastic gasket continues to press down and contacts the second step, or continues to press down, to achieve the effect of restricting the flow and ensuring stable flow changes.

[0026] This invention can be used in various products that require cost-saving measures, such as... Figure 6 On the bidet shown, such as Figure 7 The flushing cover shown is simple in structure and easy to install, achieving the effect of limiting flow rate and ensuring stable flow rate changes.
