Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of a flow balance valve according to the present invention with reference to the accompanying drawings and preferred embodiments will be made to show the following detailed description of the specific embodiments, structures, features and effects thereof.

The liquid moves from upstream to downstream in the casing 1 with the flow direction of the liquid in the casing 1 as a reference, and the upstream end of the liquid is defined as "rear" and the downstream end of the liquid is defined as "front".

Referring to fig. 1 and 2, a flow balance valve includes a housing 1, a first passage 101 for a fluid to pass through is disposed inside the housing 1, a liquid outlet 102 communicated with the first passage 101 is further disposed at a front end of the housing 1, an installation groove 103 and a step 104 are disposed on an inner wall of the housing 1, the step 104 is located at a front end of the installation groove 103, an inclined plane 105 is further disposed between the step 104 and the liquid outlet 102, and a front end of the inclined plane 105 inclines towards an axial direction close to the liquid outlet 102, so that a cross section of the front end of the first passage 101 gradually decreases.

A retainer ring 6, a flow regulating member and a sealing disk 3 are sequentially arranged in the first passage 101 from back to front, and the gap between the flow regulating member and the sealing disk 3 changes along with the change of the pressure difference.

The check ring 6 is arranged in the mounting groove 103, so that the flow regulating piece is limited at the rear part, and the flow regulating piece is prevented from being separated backwards, the check ring 6 is C-shaped, the outer diameter of the check ring 6 is larger than the inner diameter of the shell 1, when the check ring 6 is mounted, the check ring 6 needs to be forced to elastically deform, and after the check ring 6 is mounted in the mounting groove 103, the check ring 6 is restored to the original shape under the elastic action, so that the check ring is mounted in the mounting groove 103 and is not easy to fall off, and the check ring 6 is convenient to disassemble and assemble, so that the flow regulating piece is convenient to replace; of course, in other embodiments of the present invention, the mounting groove 103 and the retainer ring 6 are not required to be disposed in the housing 1, a boss may be disposed on the inner wall of the housing 1, and the flow rate adjusting member is limited by the boss, but in other embodiments, different limiting devices may be used to limit the flow rate adjusting member. The lateral wall of sealed dish 3 supports tightly on step 104, step 104 is spacing before going on sealed dish 103, be equipped with through-hole 301 on sealed dish 3, in this embodiment, the axis direction slope of the front end of the outer wall of sealed dish 3 to the liquid outlet, and the diameter of through-hole 301 is less than the diameter of liquid outlet 102, when liquid flows to liquid outlet 102 department through flow control spare, this sealed dish 3's inner wall cushions the fluid to reduce fluidic velocity of flow, avoid strikeing the low reaches component.

A sealing ring 5 is arranged between the retainer ring 6 and the flow regulating piece, and the sealing ring 5 supports the flow regulating piece to prevent the flow regulating piece from falling off in the deformation process; of course, in the embodiment of the present invention, the sealing ring 5 may not be provided, and the rear end of the flow rate adjusting member may be directly abutted against the retainer ring 6.

The flow regulating member comprises a plurality of elastic pieces 2 which are arranged in a crossed manner, wherein each elastic piece 2 is in an N-star shape, N is more than or equal to 3, in the embodiment, each elastic piece 2 is in a four-corner star shape, of course, in other embodiments of the invention, each elastic piece 2 can also be in a diamond shape, a polygon shape, an irregular shape or other shapes, when a central hole is formed in each elastic piece 2, a plurality of side holes 201 are formed between the side wall of each elastic piece 2 and the inner wall of the shell 1, in the embodiment, each elastic piece 2 is made of elastic stainless steel sheets, and of course, in other embodiments of the invention, each elastic piece 2 can also be made of other elastic materials. In this embodiment, the elastic sheet 2 is integrally mounted by the rivet 4, but may be integrally mounted by welding or other methods in other embodiments of the present invention. The center of the rivet 4 is provided with a second channel 401 for liquid to pass through, when the end of the rivet 4 passes through the central hole on the elastic sheet 2 and anchors the elastic sheets 2 into a whole, the second channel 401 is communicated with the first channel 101, so that the liquid flows from the upstream to the downstream of the flow regulating member. The elastic sheet 2 deforms along with the change of the pressure difference in the balance valve channel, when the pressure difference is increased, the elastic sheet 2 is close to the sealing disc 3, so that the gap between the elastic sheet 2 and the sealing disc 3 is reduced until the elastic sheet 2 is not deformed, and when the elastic sheet reaches the maximum deflection position, the flow of fluid is kept constant.

When the pressure difference is increased, the flow regulating piece is bent and deformed towards one side where the sealing disc 3 is located, the gap between the flow regulating piece and the sealing disc 3 is gradually reduced, the flow regulating piece stops deforming after deforming to a certain degree, the elastic piece reaches the maximum deflection position, and the flow of the fluid is kept constant at the moment; when the pressure difference decreases, the flow regulating member deforms to the side away from the sealing plate 3, the gap between the flow regulating member and the sealing plate 3 gradually becomes larger, and when the flow regulating member stops deforming, a different flow of fluid is allowed to flow through the first passage 101 during this process, which is also the case during deformation of the resilient plate to the maximum deflected position.

The flow balance valve disclosed by the invention is simple in structure, can meet the requirement of a liquid cooling system on flow regulation, does not need a special instrument to carry out complex flow balance debugging on the system, does not influence the flow of a pipeline, and further does not damage the original system balance.
