Description

Technical Field

[0001] This utility model relates to the field of flanged ball valve technology, specifically a flanged ball valve that reduces obstruction to water flow. Background Technology

[0002] Ball valves and gate valves belong to the same type of valve, the difference being that the closing element of a ball valve is a sphere. The sphere rotates around the valve body's centerline to open and close the valve. A type of flanged ball valve with a sealing gasket on the flange face has been discovered in the existing technology, a typical example being CN210687060U. The sealing gasket is fixed to the flange face by a liner, making it difficult to fall off or shift. The valve body is divided into a left valve body and a right valve body, which facilitates the disassembly and maintenance of the ball valve. However, some problems still exist, such as impurities directly contacting the valve disc, causing wear during valve disc rotation, affecting the overall service life of the flanged ball valve. Furthermore, existing flanged ball valves are manually controlled, which may lead to unnecessary losses in emergency situations if they cannot be closed or opened in time. Utility Model Content

The electric adjustment component is located below the manual adjustment component.

[0005] The manual adjustment assembly includes a first fixed frame, a first screw passing through the first fixed frame, a handle fixed to the upper side of the first screw, and the upper end of the valve disc fixed to the lower side of the first screw.

[0008] Preferably, the filter assembly includes a filter screen with conical protrusions fixed on it.

[0009] By adopting the above technical solution, impurities in the water can be filtered out by setting up a filtration structure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a flanged ball valve that reduces obstruction to water flow, such as... Figure 1 and Figure 2 As shown, the structure includes a flanged ball valve structure 1, a manual adjustment assembly 13 including a first fixing frame 131, a first screw 132 passing through the first fixing frame 131, a handle 133 fixed on the upper side of the first screw 132, and the upper end of the valve disc 12 fixed on the lower side of the first screw 132. The electric adjustment assembly 14 includes a second fixing frame 141, a first motor housing 142 fixed on the lower side of the second fixing frame 141, a motor in the first motor housing 142 being rotatably connected to a second screw 144 via a reducer 143, and the lower end of the valve disc 12 fixed on the upper side of the second screw 144.

[0024] Among them, the manual adjustment component 13 and the electric adjustment component 14 are symmetrically arranged about the central axis of the valve disc 12, and a control device for controlling the overall equipment is fixed on the first motor box 142.

[0025] Specifically, an arc-shaped scraper 24 is fixed inside the right side of the first valve seat 11, and the inner wall of the arc-shaped scraper 24 is attached to the outer wall of the valve disc 12.

[0026] In the above scheme, the operator manually rotates the handle 133. The rotation of the handle 133 causes the first screw 132 on the first fixed frame 131 to rotate, thereby opening or closing the valve disc 12 on the first valve seat 11. In case of emergency, the stepper motor in the first motor box 142 on the second fixed frame 141 drives the reducer 143 to rotate. The rotation of the reducer 143 drives the second screw 144 to rotate, thereby opening or closing the valve disc 12, increasing practicality.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flanged ball valve structure 1 is disassembled and the filter structure 2 is installed. The filter structure 2 includes a second valve seat 21, on which an inlet pipe 22 is fixed. The filter assembly 23 is disassembled and installed on the inlet pipe 22. An arc-shaped scraper 24 is provided on the right side of the conical protrusion 232. The filter assembly 23 includes a filter screen 231, on which the conical protrusion 232 is fixed.

[0028] Among them, there are two sets of filter screens 231 with different mesh densities. Multiple sets of conical protrusions 232 are fixed on the filter screens 231, and the multiple sets of conical protrusions 232 are evenly distributed on the filter screens 231.

[0029] Specifically, the arc-shaped scraper 24 is fixed to the inner wall of the right side of the second valve seat 21, and the inner wall of the arc-shaped scraper 24 is in contact with the outer wall of the valve disc 12.

[0030] In the above scheme, water flows into the inlet pipe 22 and is filtered with the assistance of the filter screen 231 inside the inlet pipe 22. The conical protrusions 232 on the filter screen 231 reduce the water flow resistance. When the valve disc 12 rotates, the surface of the valve disc 12 is cleaned with the assistance of the arc-shaped scraper 24, thereby avoiding damage to the sealing ring and affecting the service life of the flange ball valve.

[0031] like Figure 1 and Figure 3 As shown, a cleaning component 3 is installed and removed inside the filter structure 2. The cleaning component 3 includes a second motor box 31. The motor inside the second motor box 31 drives the support plate 32 to rotate. A cleaning brush 33 is fixed on the support plate 32. A receiving trough 34 passes through the water inlet pipe 22. A sealing cover 35 is installed and removed from the lower side of the receiving trough 34. Two sets of support plates 32 are provided. The two sets of support plates 32 are symmetrically arranged about the central axis of the filter screen 231.

[0032] Among them, the cleaning component 3 is provided with two sets, and the two sets of first motor boxes 142 are respectively fixed on the two sets of filter screens 231. The filter screens 231 are slidably connected to the support plate 32.

[0033] Specifically, there are three sets of receiving troughs 34, which are distributed on both sides of the two sets of filter screens 231. The sealing caps 35 are installed on the lower side of the three sets of receiving troughs 34 by thread, so as to facilitate the cleaning of impurities later.

[0034] In the above scheme, the stepper motor in the second motor box 31 drives the support plate 32 to rotate. The rotation of the support plate 32 drives the cleaning brush 33 to rotate and clean the surface of the filter screen 231. The cleaned impurities fall into the receiving trough 34. The receiving trough 34 is rotated and separated from the sealing cover 35, thereby processing the impurities.

[0035] Working principle: When using this flanged ball valve which reduces obstruction to water flow, connect the external power supply, open or close the flanged ball valve through the setting of flanged ball valve structure 1, process impurities inside the flanged ball valve through the setting of filter structure 2, and clean and filter the filter structure 2 through the setting of cleaning component 3.
