Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, and in particular to an adjustable flow ball valve seat. Background Technology

[0002] A ball valve is a type of valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the valve stem. The main function of a ball valve is to control the flow direction and flow rate of fluid, including its use as a switch and shut-off valve. The advantages of a ball valve include low fluid resistance, resistance to erosion by the medium, and the ability to close tightly in pipelines with only a 90-degree rotation and a very small torque.

[0003] Chinese Patent CN223105330U discloses an adjustable flow ball valve seat, including a valve seat body with a flow hole on the side wall. This invention utilizes a first connecting member, a mounting plate, a first threaded hole, a second threaded hole, a first threaded groove, and mounting bolts. When the first connecting member, mounting plate, and valve seat body abut against each other and are fixed by the mounting bolts to the threads of the first threaded hole, second threaded hole, and first threaded groove, hard water entering the mounting plate through the first connecting member in the inlet pipe is filtered by an ion exchange resin filter screen. The ion exchange resin in the filter screen removes heavy metal ions and impurities from the water and adjusts the water hardness. Therefore, the filtered water entering the valve seat body does not form scale in the ball groove, preventing scale deposition from corroding metal materials and extending the service life of the valve seat body.

[0004] The existing assembly of the valve seat body, mounting plate and connecting parts of the adjustable flow ball valve seat is achieved by the cooperation of threaded holes and mounting bolts to achieve a fixed connection. In actual operation, the connection method is prone to shortcomings. Since the threaded holes need to be precisely coaxially aligned at the same time, the alignment is very easy to cause difficulties due to hole position deviation during the assembly process. This increases the operational complexity of structural installation and directly leads to the extension of assembly time, resulting in a decrease in the installation efficiency between the various components of the valve seat.

[0015] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0016] Example 1; as Figure 1 - Figure 3As shown, the present invention proposes an adjustable flow ball valve seat, comprising: a valve seat body 1, a mounting plate 2, a connector a3, a connecting plate 4, and a connector b5; the mounting plate 2 is connected to one side of the valve seat body 1; the connector a3 is connected to one side of the mounting plate 2; the connecting plate 4 is connected to the other side of the valve seat body 1; the connector b5 is connected to one side of the connecting plate 4; a latching rod a101 is provided on the side of the valve seat body 1 near the mounting plate 2, and a latching groove b is provided on the side of the valve seat body 1 near the connecting plate 4; a latching groove c is provided on the side of the mounting plate 2 near the connector a3, and a latching rod b is provided on the side of the mounting plate 2 near the valve seat body 1; a latching rod c is provided on the side of the connector a3 near the mounting plate 2; a latching groove a402 is provided on the side of the connecting plate 4 near the valve seat body 1, and a latching rod d is provided on the side of the connecting plate 4 near the connector b5; a latching groove d is provided on the side of the connector b5 near the connecting plate 4. By adding a snap rod and a snap groove, the installation efficiency of the adjustable flow ball valve seat structure is improved, and the practicality of the adjustable flow ball valve seat is enhanced. A sealing ring 103 is provided on the side of the mounting plate 2 near the connector a3. The sealing ring 103 is connected to the sealing groove c, which is located on the connector a3, to improve the sealing performance of the connection between the mounting plate 2 and the connector a3.

[0017] To further explain, latching rod a101 is connected within latching groove a402, latching rod b is connected within latching groove b, latching rod c is connected within latching groove c, and latching rod d is connected within latching groove d; the valve seat body 1 is connected to a connecting piece. The multiple latching rods and latching grooves operate in the same way, increasing the usable structure and improving the structural stability of the adjustable flow ball valve seat.

[0018] To further explain, connector a3 connects to inlet pipe 301, and inlet pipe 301 is connected to sedimentation cup 302 near the lower part of connector a3. Sedimentation cup 302 and inlet pipe 301 are connected, and drain valve is connected to the lower part of sedimentation cup 302. Large particles of impurities intercepted by metal filter 202 enter sedimentation cup 302. Operators periodically operate drain valve to discharge large particles of impurities accumulated in sedimentation cup 302, thus facilitating the use of the adjustable flow ball valve seat structure.

[0019] Example 2; as Figure 1 and Figure 2 As shown, this utility model proposes an adjustable flow ball valve seat. Based on the above embodiments, this embodiment also details the specific components and mating methods of the connector, mounting plate 2, connecting plate 4 and connector b5.

[0020] Further explanation: the connecting parts include threaded holes a102, sealing rings 103, adjusting rods 104, and adjusting discs 105; four threaded holes a102 are provided, and the four threaded holes a102 are located at the four corners of the valve seat body 1. Sealing rings 103 are connected to both sides of the valve seat body 1; the valve seat body 1 is connected to the adjusting rods 104, the upper end of the adjusting rods 104 is connected to the adjusting discs 105, and the lower end is connected to the ball valve body, which is connected inside the valve seat body 1. The valve seat body 1 is provided with a flow hole, and a ball valve groove is opened on the inner wall of the flow hole. The ball valve body is connected to the ball valve groove. Both ends of the valve seat body 1 are connected to the through holes of the mounting plate 2 and the connecting plate 4, respectively. The adjusting plate 105 is a metal rotating plate. Through the adjusting plate 105, the fixed personnel can control the rotation of the adjusting rod 104 by adjusting the adjusting plate 105. It is more convenient to operate the ball valve body at the lower end of the adjusting rod 104 to rotate and control the flow in the ball valve groove. At the same time, threaded holes b are provided at the four corners of the mounting plate 2, the connecting piece a3, the connecting plate 4 and the connecting piece b5, respectively, so that they are aligned with the four threaded holes a102 of the valve seat body 1, and then they are connected and fixed with the mounting bolts.

[0021] To further explain, the inner wall of the mounting plate 2 connects the filter screen plate 201 and the metal filter screen 202, with the metal filter screen 202 positioned in front of the filter screen plate 201. A sealing groove b is provided on the side of the mounting plate 2 near the valve seat body 1, and the sealing groove b is connected to a sealing ring 103 on one side. The filter screen plate 201 is an ion exchange resin filter screen plate 201. The ion exchange resin removes heavy metal ions and impurities from the water and can adjust the water hardness. After filtration, the water entering the valve seat body 1 will not form scale, thus conveniently extending the service life of the valve seat body 1. The metal filter screen 202 intercepts large particles of impurities, extending the service life of the ion exchange resin.

[0022] To further explain, the connecting plate 4 has a sealing groove a401 on the side near the valve seat body 1, and the sealing groove a401 is connected to the sealing ring 103 on the other side; the connecting piece b5 is connected to the water outlet pipe 501. The sealing ring 103 is correspondingly provided on the side of the connecting plate 4 near the connecting piece b5, so that the connecting piece b5 is correspondingly provided with a sealing groove b. During the installation operation of the connecting plate 4 and the connecting piece b5, the sealing ring 103 is connected in the corresponding sealing groove b, which facilitates the increase of the sealing performance of the connection between the connecting plate 4 and the connecting piece b5.

[0023] The working principle of this utility model is as follows: During the assembly of the adjustable flow ball valve seat structure, by matching and setting corresponding positions of the valve seat body 1, mounting plate 2, connecting plate 4, connector a3, and connector b5, a pre-positioning function is established. When the valve seat body 1 is assembled with the mounting plates 2 and connecting plates 4 on both sides, the connecting rod a101 on one side of the valve seat body 1 is connected to the locking groove a402, and the locking rod b on the mounting plate 2 is connected to the locking groove b. Then, the locking groove c on the mounting plate 2 is connected to the locking rod c on the connector a3, and the locking rod d on the connecting plate 4 is connected to the locking groove d on the connector b5. When the valve seat body 1, mounting plate 2, connecting plate 4, connector a3, and connector b5 are engaged with their corresponding locking grooves, the valve seat is quickly completed. The initial assembly of the body 1, mounting plate 2, connecting plate 4, and two connecting parts ensures that the threaded holes on each component are aligned coaxially. Then, the mounting bolts are connected to the threaded holes on each component, facilitating the assembly efficiency of the adjustable flow ball valve seat structure. Simultaneously, the stable engagement of the snap-fit ​​rod and snap-fit ​​groove, along with the rigid connection to the subsequent mounting bolts, forms a double connection guarantee. The snap-fit ​​structure can share the pressure borne by the mounting bolts, preventing deformation or fatigue damage due to excessive force on the bolts alone. During long-term valve opening and closing regulation, the snap-fit ​​connection effectively limits the relative displacement of each component, preventing loosening of the threaded connection due to vibration, thus improving the usability of the adjustable flow ball valve seat. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
