Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to a ball valve type with filter exhaust valve. Background Technology

[0002] Exhaust valves are a commonly used type of valve. Patent publication CN214534677U discloses a filter-type exhaust valve. In this type of exhaust valve, a cylindrical filter screen is fitted onto a ceramic valve core. The cylindrical filter screen is used to filter impurities. However, since the cylindrical filter screen is fitted onto the ceramic valve core, and the ceramic valve core needs to rotate during use, this type of exhaust valve causes some wear on both the ceramic valve core and the filter screen. If the liquid medium contains large particulate impurities, it may directly cause jamming between the ceramic valve core and the cylindrical filter screen. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a ball valve type exhaust valve with filter.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A ball valve type with filter exhaust valve includes a valve body, in which a first valve chamber, a second valve chamber, and a third valve chamber are disposed. A valve ball is rotatably disposed in the first valve chamber, and an exhaust assembly is disposed in the third valve chamber. The two ends of the second valve chamber are respectively connected to the first valve chamber and the third valve chamber. The valve body also includes a filter screen cylinder. The first valve chamber, the second valve chamber, and the third valve chamber are distributed in a zigzag pattern. The filter screen cylinder is disposed in the second valve chamber, and the second valve chamber and the third valve chamber are separated by the cylinder wall of the filter screen cylinder. The cylinder wall of the filter screen cylinder is close to the inner wall of the second valve chamber.

[0006] In this type of exhaust valve, the valve ball controls the opening and closing of the first valve chamber. When the first valve chamber is open, the liquid medium enters the first valve chamber, flows through the valve ball, enters the second valve chamber, and then flows through the mesh holes on the filter cylinder into the third valve chamber. During this process, because the first, second, and third valve chambers are arranged in a zigzag pattern, the liquid follows a zigzag path. This not only prevents the liquid medium from directly impacting the filter cylinder wall but also reduces the liquid flow velocity and noise. Furthermore, since the filter cylinder and valve ball are separate, the valve ball does not contact the filter cylinder during operation. Therefore, the valve ball experiences less wear during rotation and will not cause wear to the filter cylinder, reducing the probability of particulate matter in the liquid clogging the mesh holes of the filter cylinder.

[0007] In summary, by separating the filter screen barrel and the valve ball in this type of exhaust valve, and by making the internal valve cavity zigzag-shaped, the wear of the filter screen barrel and the valve ball is reduced during operation, and the probability of media particles clogging the filter screen barrel is also reduced.

[0008] Optionally, a valve stem is provided on the valve ball, a first O-ring is provided between the valve stem and the valve body, a handle is connected to the valve stem and the handle is located outside the valve body, and a sealing ring is provided in the first valve cavity for contacting the valve ball.

[0009] The function of the valve stem is to rotate it. The sealing ring contacts the valve ball to provide a seal.

[0010] Optionally, a plug is provided on the valve body, and a second O-ring is provided between the plug and the valve body. The step on the inner wall of the plug abuts against one end of the filter screen cylinder.

[0011] Optionally, it also includes a valve cover, which is disposed at one end of the valve body, and a sealing gasket is provided between the valve cover and the valve body.

[0012] Optionally, the venting assembly includes a float, a crossbar, a rubber plug, a core rod, and a spring. The float is movably disposed within the third valve chamber. One end of the crossbar is engaged with the float. The rubber plug is used to press against the vent hole on the valve cover. The core rod is detachably disposed on the valve cover. The spring is disposed between the core rod and the crossbar, and both ends of the spring are connected to the core rod and the crossbar, respectively.

[0013] In this type of exhaust assembly, the float moves the crossbar. When the liquid level in the third valve chamber is lower than the set value, the crossbar blocks the exhaust port with a rubber plug at one end. When the liquid level in the third valve chamber is lower than the set value, the rubber plug on the crossbar does not block the exhaust port, and the gas is discharged through the exhaust port and then through the vent on the core rod.

[0014] Optionally, it also includes a decorative cap, wherein the valve cover has an opening, the decorative cap is disposed on the opening of the valve cover, and a third O-ring is provided between the decorative cap and the valve cover.

[0015] In order to allow for smooth venting, the valve cap and valve cover need to be loosened to a certain extent to ensure that the third O-ring does not completely seal the gap between the valve cap and the valve cover, allowing gas to escape through the gap.

[0016] Optionally, one end of the valve body is fitted with an internal thread cap.

[0017] The beneficial effects of this utility model are: by separating the filter screen barrel and the valve ball, and making the internal valve cavity zigzag-shaped, the wear of the filter screen barrel and the valve ball is reduced during operation, and the probability of medium particles clogging the filter screen barrel is reduced.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0025] As attached Figure 1 and appendix Figure 2 As shown, a ball valve type with filter exhaust valve includes a valve body 4, which has a first valve chamber 401, a second valve chamber 402, and a third valve chamber 403. A valve ball 3 is rotatably disposed in the first valve chamber 401, and an exhaust assembly is disposed in the third valve chamber 403. The two ends of the second valve chamber 402 are respectively connected to the first valve chamber 401 and the second valve chamber 402. The valve body also includes a filter screen cylinder 5. The first valve chamber 401, the second valve chamber 402, and the third valve chamber 403 are arranged in a zigzag pattern. The filter screen cylinder 5 is disposed in the second valve chamber 402, and the second valve chamber 402 and the third valve chamber 403 are separated by the cylinder wall of the filter screen cylinder 5. The cylinder wall of the filter screen cylinder 5 is close to the inner wall of the second valve chamber 402.

[0026] In this type of exhaust valve, the valve ball 3 controls the opening and closing of the first valve chamber 401. When the first valve chamber 401 is in the open state, the liquid medium enters the first valve chamber 401, flows through the valve ball 3, enters the second valve chamber 402, and then flows through the mesh holes on the filter cylinder 5 into the third valve chamber 403. In the above process, since the first valve chamber 401, the second valve chamber 402, and the third valve chamber 403 are arranged in a zigzag pattern, the liquid flows along a zigzag line. This not only avoids the liquid medium directly impacting the cylinder wall of the filter cylinder 5, but also reduces the liquid flow rate and noise. At the same time, since the filter cylinder 5 and the valve ball 3 are set separately, the valve ball 3 will not contact the filter cylinder 5 during operation. Therefore, the wear of the valve ball 3 is small and will not cause wear to the filter cylinder 5, reducing the probability of particulate media in the liquid clogging the mesh holes of the filter cylinder 5.

[0027] In summary, by separating the filter screen barrel and valve ball 3 and making the internal valve cavity zigzag-shaped, the wear of the filter screen barrel 5 and valve ball 3 is reduced during operation, and the probability of medium particles clogging the filter screen barrel is also reduced.

[0028] As attached Figure 1 and appendix Figure 2 As shown, a valve stem 11 is provided on the valve ball 3, and a first O-ring 12 is provided between the valve stem 11 and the valve body 4. A handle 13 is connected to the valve stem 11, and the handle 13 is located outside the valve body 4. A sealing ring 2 is provided in the first valve cavity 401, and the sealing ring 2 is used to contact the valve ball 3.

[0029] The function of valve stem 11 is to rotate valve stem 11. Sealing ring 2 contacts valve ball 3 to achieve a sealing effect.

[0030] As attached Figure 1 and appendix Figure 2 As shown, a plug 7 is provided on the valve body 4, and a second O-ring 6 is provided between the plug 7 and the valve body 4. The step on the inner wall of the plug 7 abuts against one end of the filter screen cylinder 5.

[0031] As attached Figure 1 and appendix Figure 2 As shown, it also includes a valve cover 10, which is disposed at one end of the valve body 4, and a sealing gasket 9 is provided between the valve cover 10 and the valve body 4.

[0032] As attached Figure 1 and appendix Figure 2 As shown, the exhaust assembly includes a float 8, a crossbar 19, a rubber plug 18, a core rod 16, and a spring 17. The float 8 is movably disposed in the third valve chamber 403. One end of the crossbar 19 is engaged with the float 8. The rubber plug 18 is used to press against the exhaust hole on the valve cover 10. The core rod 16 is detachably disposed on the valve cover 10. The spring 17 is disposed between the core rod 16 and the crossbar 19, and both ends of the spring 17 are connected to the core rod 16 and the crossbar 19, respectively.

[0033] In this type of exhaust assembly, the float 8 drives the crossbar 19 to move. When the liquid level in the third valve chamber 403 is lower than the set value, the crossbar 19 blocks the exhaust hole through the rubber plug 18 at one end. When the liquid level in the third valve chamber 403 is lower than the set value, the rubber plug 18 on the crossbar 19 does not block the exhaust hole, and the gas is discharged through the exhaust hole and then through the vent 1601 on the core rod 16.

[0034] As attached Figure 1 and appendix Figure 2 As shown, it also includes a flower cap 14. The valve cover 10 has an opening, the flower cap 14 is set on the opening of the valve cover 10, and a third O-ring seal 15 is provided between the flower cap 14 and the valve cover 10.

[0035] In order to allow for smooth venting, the valve cap 14 and the valve cover 10 need to be loosened to a certain extent to ensure that the third O-ring 15 does not completely seal the valve cap 14 and the valve cover 10, so that the gas can escape from the gap.

[0036] As attached Figure 1 and appendix Figure 2 As shown, one end of the valve body 4 is connected to an internal thread cap 1.

[0037] The above-described embodiments only illustrate some aspects of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
