Description

Technical Field

[0001] The invention relates to a combination valve, in particular to a direct drinking water combination valve with filtering, non-return and exhaust functions and a use method thereof. Background Art

[0002] Direct drinking water, also known as activated water and healthy living water, is filtered by nanofiltration separation membrane devices, etc., to kill viruses and bacteria in it and filter out the discoloration, odor, residual chlorine, ozone, hydrogen sulfide, bacteria, viruses, and heavy metals in tap water. It blocks suspended particles to improve water quality, while retaining trace elements that are beneficial to the human body, and softens the water with ion exchangers. Finally, the water body is energized and mineralized through the action of high-energy biochemical ceramics, reaching the standard of direct drinking healthy water fully in line with the World Health Organization's published standards.

[0003] In the field of direct drinking water, a variety of valves such as gate valves, filters, check valves, exhaust valves, etc. are generally used to control flow, prevent backflow, filter impurities, and discharge gas in the water. However, the existing valves have single functions. For example, gate valves can only adjust the flow of water, check valves control the flow direction of the medium, filter impurities in the filter medium, and exhaust valves discharge gas in the medium. In order to meet the requirements of direct drinking water, all valves are indispensable, resulting in a large control system, cumbersome operation, and inconvenient installation, which cannot meet the index requirements of direct drinking water. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing one-way valve for direct drinking water cannot meet the demand for direct drinking water. To this end, a direct drinking water combination valve with filtering, non-return and exhaust functions and a use method thereof are provided.

[0005] The technical solution of the present invention is: a direct drinking water combination valve with filtering, non-return and exhaust functions, comprising: a valve body channel; a filter, the filter is installed inside the valve body channel and close to the water inlet end of the valve body channel; an exhaust valve, the exhaust valve is installed at the top of the valve body channel and close to the water outlet end of the filter; a gate valve, the gate valve is installed in the middle of the valve body channel; a check valve, the check valve is installed inside the valve body channel and close to the water outlet end of the valve body channel; a bubble floating mechanism, the bubble floating mechanism is installed in the valve body channel and is located between the exhaust valve and the gate valve to make the bubbles in the fluid float.

[0006] The bubble floating mechanism in the above scheme includes: a column, which is vertically installed in the valve body channel; a horizontal turntable, which is rotatably connected to the column; two rotating shafts, which are installed on the inner walls on both sides of the valve body channel; a vertical turntable, which is rotatably connected to the rotating shaft and has a gap with the horizontal turntable; a boss, which is formed at the edge of the vertical turntable and constrains the horizontal turntable inside.

[0007] In the above solution, the upright column and the horizontal turntable are connected via threaded fitting.

[0008] An improvement of the above solution is that the edge of the horizontal turntable has serrations.

[0009] A further improvement of the above solution is that the edge of the vertical rotating disk has serrations.

[0010] The interior of the horizontal turntable in the above solution is a hollow cavity.

[0011] The method for using the direct drinking water combination valve with filtering, non-return and exhaust functions includes the following steps: the tap water enters the filter through the water inlet end of the valve body channel, and after being filtered, it impacts the bubble floating mechanism, so that the horizontal turntable and the vertical turntable rotate, generating centrifugal force to drive the bubbles to float, and at the same time, the horizontal turntable moves up and down on the column to expand the influence range of the centrifugal force, and the floating bubbles enter the exhaust valve for discharge, and the tap water passing through the bubble floating mechanism passes through the gate valve and the non-return valve in turn and is discharged from the water outlet end of the valve body channel. .

[0012] The beneficial effects of the present invention are that the combined valve has filtering, non-return and exhaust functions, and the bubble floating mechanism can allow the bubbles to quickly enter the exhaust valve to avoid the occurrence of air blocking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0015] The present invention needs to comprehensively consider multiple factors, including structural design, material selection, sealing performance, and ease of operation. The following is a possible design example: 1. Overall structure: The combined valve consists of four parts: valve body, filter, check valve and exhaust valve. The parts are assembled by threaded connection or flange connection.

[0016] 2. Valve body design: The valve body is made of stainless steel, which has good corrosion resistance and mechanical strength. The valve body is equipped with a fluid channel to guide the water flow through the filter, check valve and exhaust valve.

[0017] 3. Filter design: The filter is located at the water inlet of the valve body and uses replaceable filter elements, such as PP cotton, activated carbon, etc., to remove impurities such as suspended matter, colloids, bacteria, etc. in the water. The filter housing is made of transparent material to facilitate observation of the use of the filter element.

[0018] 4. Check valve design: The check valve is located downstream of the filter to prevent water backflow and protect the safety of subsequent pipelines and equipment. The check valve uses spring reset or gravity reset to ensure that it can automatically close when the water is cut off.

[0019] 5. Exhaust valve design: The exhaust valve is located on the top or side of the valve body and is used to remove air from the pipeline to avoid air blockage. The exhaust valve adopts manual or automatic exhaust mode, which can be selected according to actual needs.

[0020] 6. Operational convenience: Standardized interfaces are used between various components to facilitate installation and maintenance. The filter and exhaust valve are equipped with quick disassembly devices to facilitate replacement of filter elements and exhaust.

[0021] 7. Sealing performance: Rubber sealing rings or PTFE sealing gaskets are used at each connection to ensure good sealing performance. Check the wear of the seals regularly and replace damaged seals in time.

[0022] 8. Safety measures: A pressure gauge and a thermometer are installed on the valve body to monitor the changes in water pressure and water temperature in real time. A safety valve is configured to automatically release pressure when the water pressure exceeds the set value to prevent the pipeline from rupturing.

[0023] This direct drinking water combined valve design with filtering, non-return and exhaust functions not only improves the safety and reliability of the direct drinking water system, but also reduces maintenance costs and operating difficulties. Through reasonable structural design and material selection, it can ensure that the valve maintains good performance and stability during long-term use.

[0024] like Figure 1-2 As shown, a direct drinking water combination valve with filtering, non-return and exhaust functions includes: a valve body channel 1; a filter 2, which is installed inside the valve body channel and close to the water inlet end of the valve body channel; an exhaust valve 3, which is installed at the top of the valve body channel and close to the water outlet end of the filter; a gate valve 4, which is installed in the middle of the valve body channel; a check valve 5, which is installed inside the valve body channel and close to the water outlet end of the valve body channel; and a bubble floating mechanism, which is installed in the valve body channel and located between the exhaust valve and the gate valve to float the bubbles in the fluid.

[0025] The method for using a direct drinking water combination valve with filtering, non-return and exhaust functions comprises the following steps: tap water enters the filter through the water inlet end of the valve body channel, impacts the bubble floating mechanism after being filtered, causes the horizontal turntable and the vertical turntable to rotate, generates centrifugal force to drive the bubbles to float, and at the same time the horizontal turntable moves up and down on the column to expand the influence range of the centrifugal force, and the floating bubbles enter the exhaust valve in time for discharge to avoid air blockage, and the tap water passing through the bubble floating mechanism passes through the gate valve and the non-return valve in turn and is discharged from the water outlet end of the valve body channel.

[0026] The filter is preferably a Y-type filter, which is installed obliquely in the valve body channel to purify the tap water, and the gate valve is used to control the on-off of the tap water. The check valve is preferably a rubber flap check valve. The bubble floating mechanism is used to agitate the bubbles in the tap water so that the bubbles quickly float to the exhaust valve to prevent the bubbles contained in the tap water from being unable to enter the exhaust valve and remaining in the valve body channel when the tap water flow rate is too fast.

[0027] Specifically, the bubble floating mechanism includes: a column 6, which is vertically installed in the valve body channel; a horizontal turntable 7, which is rotatably connected to the column; two rotating shafts 8, which are installed on the inner walls of the valve body channel on both sides; a vertical turntable 9, which is rotatably connected to the rotating shaft and matches the gap between the vertical turntable and the horizontal turntable; a boss 10, which is formed on the edge of the vertical turntable and constrains the horizontal turntable. The column serves as a support for the rotation of the horizontal turntable. The horizontal turntable rotates around the column, driving the water flow to generate horizontal vortices, so that the bubbles are driven by centrifugal force. At the same time, the vertical turntable rotates around the rotating shaft in the vertical direction, driving the water flow to generate vertical vortices, so that the bubbles are driven by centrifugal force. The cooperation between the horizontal turntable and the vertical turntable expands the scope of action of the centrifugal force. At the same time, the gap between the horizontal turntable and the vertical turntable brings turbulence, ensuring that the bubbles are quickly driven to the water surface and then enter the exhaust valve. The boss is used to constrain the movement range of the horizontal turntable.

[0028] As a preferred example of the present invention, the column and the horizontal turntable are connected by threaded cooperation. When the water flow hits the horizontal turntable, the horizontal turntable rotates and then moves in the height direction of the column, thereby expanding the horizontal vortex range. The horizontal vortex and the vertical vortex merge to improve the bubble floating effect.

[0029] In order to ensure the smooth self-rotation of the horizontal turntable, the edge of the horizontal turntable has serrations. The serrations also have the function of cutting the water flow. Similarly, the edge of the vertical turntable has serrations.

[0030] In order to improve the rising sensitivity of the horizontal turntable, the interior of the horizontal turntable is a hollow cavity. Due to its hollow structure, it is less affected by gravity, so that the horizontal turntable can rise quickly.
