Description

Technical Field

[0001] This utility model relates to an improvement of a quick-connect ball valve, and in particular a three-part quick-connect ball valve with a filtering function. Background Technology

[0002] The three-way quick-connect ball valve is a type of ball valve that combines three-way functionality with a quick-connect connection. It is widely used in various fluid systems and generally consists of a valve body containing a spherical valve core, with an operating section at the top. The valve body is the outer shell of the valve, providing installation space for the spherical valve core, valve seat, and other components. A quick-connect interface at the inlet allows for connection to a pipeline. The valve body is typically made of metal materials such as cast steel or stainless steel, possessing sufficient strength and corrosion resistance to withstand the pressure and chemical erosion of the medium.

[0003] Because this ball valve has a built-in filter, the filter needs to intercept impurities in the medium. These impurities vary in size and are suspended in the liquid. Over time, a large amount of impurities accumulate on the filter surface, causing it to become clogged. The filter becomes clogged relatively quickly, and replacing it is troublesome. Once clogged, the flow of the medium is hindered, increasing the pressure difference across the valve and potentially affecting the normal operation of the entire system. Utility Model Content

[0004] To overcome the shortcomings of existing three-way quick-connect ball valves with filters, which are prone to clogging and difficult to replace, this utility model provides a three-way quick-connect ball valve with a filtering function.

[0005] The technical solution of this utility model to solve its technical problem is: a three-part quick-connect ball valve with filtering function, comprising a three-part valve body, the valve body including a main body, the two ends of the main body respectively provided with an inlet and a first outlet, a normally open flow channel formed in the middle of the main body, and a filter cartridge provided in the normally open flow channel; a secondary pipe body is provided horizontally on the main body, the end of the secondary pipe body is a second outlet, and a quick-connect assembly is provided at the second outlet; a ball valve core is provided in the secondary pipe body, and the rotation of the ball valve core can block or open the second outlet to form an adjustable flow. The valve body is provided with a rotatable operating part, which is fixedly connected to the ball valve core by a valve stem. The filter cartridge includes a hollow filter frame with an inner filter cylinder and an outer filter cylinder. A gap is provided between the inner and outer filter cylinders. The mesh size of the inner filter cylinder is lower than that of the outer filter cylinder. The adjustable flow channel opens outside the outer filter cylinder and is connected to the normally open flow channel through the outer filter cylinder, the gap between the cylinders, and the inner filter cylinder. The filter frame is provided with a front sealing ring and a rear sealing ring, so that the normally open flow channel cannot be directly connected to the adjustable flow channel.

[0006] To increase the service life and filtration effect of the filter cartridge, the gap between the cartridges is thicker on the side closer to the adjustable flow channel and thinner on the side farther from the adjustable flow channel.

[0007] In a preferred embodiment, the inner filter cylinder is eccentrically positioned, the filter frame is provided with a positioning groove, and the main pipe is provided with a positioning protrusion. When the filter cylinder is installed on the normally flowing channel, the positioning protrusion is inserted into the positioning groove.

[0008] A preferred embodiment of a filter holder comprises a front ring, a middle ring, and a rear ring, wherein the front ring, the middle ring, and the rear ring are connected by a longitudinal beam; the front sealing ring is located on the front ring, and the rear sealing ring is located on the rear ring.

[0009] In a preferred embodiment, the longitudinal beams are provided in a cross-shaped arrangement.

[0010] The materials of each component of the filter cartridge are optimized. The filter frame is made of polypropylene, the inner filter screen is made of stainless steel (304 stainless steel can be selected), and the outer filter screen is made of aluminum alloy (6063 aluminum alloy can be selected).

[0011] In one preferred embodiment, the operating part is a knob.

[0012] For ease of use, the knob is equipped with indicator markings.

[0013] Furthermore, a travel stop block is provided below the knob to limit the rotation angle of the knob. The travel stop block can prevent the knob and the ball valve core from rotating excessively.

[0014] To facilitate the connection of the water inlet, a locking nut is provided on the water inlet.

[0015] In use, the inlet of the three-part quick-connect ball valve is installed on the inlet pipe, the first outlet is connected to the first outlet pipe, and the quick-connect assembly cover of the second outlet is inserted into the second outlet pipe.

[0016] When fluid enters the three-way valve, it first comes into contact with the inner filter screen. The inner filter screen has larger mesh openings, which can intercept some larger impurities. The fluid enters the gap between the screens and then flows through the outer filter screen. The outer filter screen has smaller mesh openings, which can filter out relatively small impurity particles in the fluid. After fine filtration, the fluid enters the adjustable flow channel. The ball valve core in the adjustable flow channel is controlled by a knob. The adjustable flow channel can adjust the flow rate and direction of the fluid according to actual needs.

[0017] Because the filter cartridge intercepts a large number of impurities during the filtration process, the eccentrically designed gaps between the cartridges can reserve a large amount of space for liquid flow in areas with high flow rates, reducing the possibility of filter cartridge clogging.

[0018] The beneficial effects of this utility model are as follows: 1. The double-layer filter structure distributes the filtration pressure, preventing a single filter from experiencing a decrease in filtration efficiency due to overload. After the inner coarse filter cylinder intercepts some impurities, the outer fine filter cylinder further filters the remaining impurities, making the entire filtration process more stable and reliable. Even in fluid environments with high impurity content, it can maintain good filtration performance, thus preventing hard impurities from accumulating on the ball valve core and rusting it. 2. The second outlet is equipped with a quick-connect assembly, allowing for pipe connection via a straight-insertion water pipe. Disassembly is not required using complex tools; simply pressing the quick-connect connector unlocks the pipe, quickly separating it from the system for easy maintenance or replacement. This reduces equipment downtime and minimizes the impact on production or use. 3. With the inner filter cylinder eccentrically positioned, fluid enters the middle of the filter cylinder. Large particles are first filtered by the inner filter cylinder, and then the fluid enters the larger gap at the top, which can bear a larger filtration load at the water-facing end, thereby extending the service life of the entire filter cylinder.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1 Combined with appendix Figures 1 to 6A three-part quick-connect ball valve with filtering function includes a three-part valve body 1.

A secondary body 7 is horizontally arranged on the main body 2, with a second outlet 8 at one end. A quick-connect assembly 9 is installed at the second outlet 8. A ball valve core 10 is installed inside the secondary body 7. The ball valve core 10 can be rotated to block or open the second outlet 8 to form an adjustable flow channel 11. The valve body 1 is provided with a rotatable operating part 12. The operating part 12 and the ball valve core 10 are fixed together by a valve stem 13; the filter cartridge 6 includes a hollow filter frame 14, on which an inner filter screen 15 and an outer filter screen 16 are provided, and an inter-tube gap 17 is provided between the inner filter screen 15 and the outer filter screen 16. The mesh count of the inner filter screen 15 is lower than that of the outer filter screen 16. The adjustable flow channel 11 opens outside the outer filter screen 16, and the adjustable flow channel 11 is connected to the normally open flow channel 5 through the outer filter screen 16, the inter-tube gap 17, and the inner filter screen 15; the filter frame 14 is provided with a front sealing ring 18 and a rear sealing ring 19, so that the normally open flow channel 5 cannot be directly connected to the adjustable flow channel 11.

[0027] To increase the service life and filtration effect of the filter cartridge 6, the gap 17 between the cartridges is thicker on the side closer to the adjustable flow channel 11 and thinner on the side farther away from the adjustable flow channel 11.

[0028] In a preferred embodiment, the inner filter cylinder 15 is eccentrically positioned, the filter frame 14 is provided with a positioning groove 20, and the main body 2 is provided with a positioning protrusion 21. When the filter cylinder 6 is installed on the normally open flow channel 5, the positioning protrusion 21 is inserted into the positioning groove 20.

[0029] A preferred embodiment of a filter holder 14 is comprising a front ring 22, a middle ring 23, and a rear ring 24, wherein the front ring 22, the middle ring 23, and the rear ring 24 are connected by a longitudinal beam 25; the front sealing ring 18 is located on the front ring 22, and the rear sealing ring 19 is located on the rear ring 24.

[0030] In a preferred embodiment, the longitudinal beams 25 are provided in a cross-shaped arrangement.

[0031] The materials of each component of the filter cartridge 6 are optimized. The filter frame 14 is a polypropylene filter frame 14, the inner filter screen cylinder 15 is a stainless steel inner filter screen cylinder 15, which can be 304 stainless steel, and the outer filter screen cylinder 16 is an aluminum alloy outer filter screen cylinder 16, which can be 6063 aluminum alloy.

[0032] In one preferred embodiment, the operating part 12 is a knob.

[0033] For ease of use, the knob is equipped with indicator markings.

[0034] Furthermore, a travel stop block 26 is provided below the knob to limit the rotation angle of the knob. The travel stop block 26 can prevent the knob and the ball valve core 10 from rotating excessively.

[0035] To facilitate the connection of the water inlet 3, a locking nut 27 is provided on the water inlet 3.

[0036] In this embodiment, the inlet 3 of the three-part quick-connect ball valve is installed on the inlet pipe, the first outlet 4 is connected to the first outlet pipe, and the cover of the quick-connect assembly 9 of the second outlet 8 is inserted into the second outlet pipe.

[0037] When the fluid enters the three-way valve, it first comes into contact with the inner filter cylinder 15. The inner filter cylinder 15 has a larger mesh size, which can intercept some larger impurities. The fluid enters the gap 17 between the cylinders and then flows through the outer filter cylinder 16. The outer filter cylinder 16 has a smaller mesh size, which can filter out relatively small impurity particles in the fluid. After fine filtration, it enters the adjustable flow channel 11. The ball valve core 10 in the adjustable flow channel 11 is controlled by a knob. The adjustable flow channel 11 can adjust the flow rate and direction of the fluid according to actual needs.

[0038] Because filter cartridge 6 intercepts a large number of impurities during the filtration process, the eccentrically designed gap between the cartridges can reserve a large amount of space for liquid flow in areas with high flow rates, reducing the possibility of clogging of filter cartridge 6.

[0039] The beneficial effects of this utility model are as follows: 1. The double-layer filter structure distributes the filtration pressure, preventing a single filter from experiencing a decrease in filtration efficiency due to overload. After the inner coarse filter cylinder intercepts some impurities, the outer fine filter cylinder further filters the remaining impurities, making the entire filtration process more stable and reliable. Even in fluid environments with high impurity content, it can maintain good filtration performance, thus preventing hard impurities from accumulating on the ball valve core and rusting it. 2. The second outlet is equipped with a quick-connect assembly, allowing for pipe connection via a straight-insertion water pipe. Disassembly is not required using complex tools; simply pressing the quick-connect connector unlocks the pipe, quickly separating it from the system for easy maintenance or replacement. This reduces equipment downtime and minimizes the impact on production or use. 3. With the inner filter cylinder eccentrically positioned, fluid enters the middle of the filter cylinder. Large particles are first filtered by the inner filter cylinder, and then the fluid enters the larger gap at the top, which can bear a larger filtration load at the water-facing end, thereby extending the service life of the entire filter cylinder.
