Description

Technical Field

[0001] This application relates to the technical field of seawater desalination, and specifically discloses an anti-clogging water valve for seawater desalination. Background Art

[0002] Seawater desalination projects are mainly applied to places that need a stable supply of fresh water, such as ensuring drinking water for coastal residents and make-up water for industrial boilers. In the prior art, methods such as seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method are used to obtain fresh water from seawater. Among them, the reverse osmosis method and the distillation method are the mainstream methods in the market.

[0003] During the application of seawater desalination, a number of pipelines need to be arranged and installed to achieve the flow of water, including fresh water flow and seawater flow. For the pipeline system used for seawater circulation, water valves are also installed between each pipeline channel and between the pipeline and equipment to respectively control the direction, pressure, and flow rate of the internal flowing medium, that is, to control the seawater flowing inside the pipeline.

[0004] However, for the water valves used in seawater desalination projects, because a lot of impurities are carried in the initially introduced seawater, impurities will accumulate inside the water valves, resulting in clogging of the water valves and affecting the supply of seawater.

[0005] Therefore, in view of this, the inventor provides an anti-clogging water valve for seawater desalination to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to solve the problem that impurities will accumulate inside the traditional water valve, resulting in clogging of the water valve caused by the accumulated impurities.

[0007] To achieve the above purpose, the basic scheme of the present utility model provides an anti-clogging water valve for seawater desalination, including a valve body, a valve seat arranged inside the valve body, a valve rod rotatably connected to the valve body and passing through the valve seat, and a valve core coaxially fixed on the valve rod and capable of closing the valve seat. An inspection opening is opened at the bottom of the valve body, and a bottom plate for closing the inspection opening is detachably connected. A filter support with its top fitting the valve seat is arranged on the bottom plate. A through hole one for the valve rod to pass through is opened on the filter support. A filter screen one is fixedly connected to one end of the filter support fitting the valve seat, and the filter screen one covers the valve core. A stirring mechanism driven by water flow is sleeved outside a section of a connecting rod extending into the filter support.

[0008] Further, a through hole two for the valve rod to pass through and capable of being closed by the valve core is opened on the valve seat. The through hole two consists of two sections, including a conical section and a cylindrical section from top to bottom.

[0009] Further, a sleeve for the valve rod to extend into and covering the outside of the valve rod is arranged on the bottom plate. The filter support is arranged at the top of the sleeve, and the sleeve is communicated with the through hole one.

[0010] Furthermore, the filter bracket includes a bottom horizontal plate fixedly connected to the top of the sleeve, a top horizontal plate arranged above the bottom horizontal plate, and a vertical plate fixedly connected between the bottom horizontal plate and the top horizontal plate. A through hole is opened through the top horizontal plate and the bottom horizontal plate, and a filter groove is opened at the top horizontal plate where the valve seat is attached, and a filter screen is fixed in the filter groove.

[0011] Furthermore, the stirring mechanism includes a rotating tube rotatably connected between the top horizontal plate and the bottom horizontal plate and inclined blades circumferentially fixed to the outside of the rotating tube and driven by water flow. The rotating tube is coaxially sleeved on the outside of the valve stem.

[0012] The principle and effect of this scheme are:

[0013] 1. Compared with the prior art, the utility model directly installs a bottom plate with a filter bracket from the inspection port at the bottom of the valve body. Through the filter screen 1 covering the valve core on the filter bracket, when the two side chambers directly separated by the opening and closing in the valve body are connected, it can play a filtering role, and filter out impurities in the seawater on the inner side of the filter screen 1. In addition, a stirring mechanism is also provided on the inner side of the filter bracket. The impurities blocked on the filter screen 1 can be peeled off through the stirring mechanism to prevent the water valve from being blocked during long-term use, thereby solving the problem that impurities are accumulated inside the traditional water valve and the water valve is blocked by the accumulated impurities.

[0014] 2. Compared with the prior art, after long-term use, the utility model can remove the filter bracket and the stirring mechanism by removing the bottom plate, and clean the impurities filtered out from the inside of the filter bracket and the impurities remaining in the valve body of the water valve, so as to facilitate subsequent reuse.

When the valve core 5 closes the valve seat 4, two chambers separated by the valve seat 4 are formed inside the valve body 1.

[0024] Specifically, two ends of the valve body 1 are respectively formed with connecting ports for connecting the external pipeline with the internal chamber, and a valve cover is installed on the top of the valve body 1. The valve cover is provided with an internal thread hole for the valve stem 3 to extend into, and a section of external thread is provided on the valve stem 3 to be threadedly connected with the internal thread hole. The valve seat 4 is provided with a through hole 2 for the valve stem 3 to pass through and which can be closed by the valve core 5. The through hole 2 is composed of two sections, including a conical section and a cylindrical section from top to bottom, and the valve core 5 can fit the conical section and the cylindrical section 1 to close the through hole 2.

[0025] In this embodiment, the bottom of the valve body 1 is provided with an inspection port 7 and is provided with a bottom plate 2 which can close the inspection port 7. A filter bracket is installed on the bottom plate 2, and a through hole 1 is provided on the filter bracket for the valve stem 3 to pass through.

[0026] A sleeve 6 is also integrally formed on the bottom plate 2 , and the sleeve 6 is coaxially arranged with the valve stem 3 . When the bottom plate 2 is connected to the bottom of the valve body 1 , the bottom end of the valve stem 3 extends into the sleeve 6 and is wrapped by the sleeve 6 .

[0027] The filter support includes a bottom horizontal plate, a top horizontal plate 9 arranged above the bottom horizontal plate, and a vertical plate 13 fixedly installed between the bottom horizontal plate and the right end of the top horizontal plate 9. A plurality of support rods 8 are fixedly installed between the bottom of the bottom horizontal plate and the top of the sleeve 6.
