Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a three-piece three-way reversing bottom ball valve for tanks. Background Technology

[0002] In certain applications requiring high cleanliness and tight sealing, bottom valves installed at the bottom of pressure vessels, with their straight-channel design, are prone to creating dead zones within the valve cavity. This can lead to the residue of viscous or particulate media (such as asphalt or resin), necessitating frequent cleaning. If the seals are not replaced promptly after prolonged use, wear or crystallization can also cause internal leakage, especially in highly corrosive media. In the event of a leak, the entire valve must be shut down and disassembled for inspection and repair. Utility Model Content

[0003] To solve the above problems, this utility model provides a three-piece three-way reversing tank bottom ball valve.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a three-piece three-way reversing tank bottom ball valve, including a main valve body, with a tank connection end and a connection end respectively sealed to both ends of the main valve body, a valve seat and a valve ball installed inside the main valve body, a valve stem sealed to the main valve body, packing material provided in the valve stem channel, a packing gland installed on the packing material, a Y-shaped channel welded to the main valve body, and a loose flange II fitted outside the Y-shaped channel.

[0005] Furthermore, the two ends of the main valve body are respectively sealed and connected to the tank connection end and the connection end through the valve body seal.

[0006] Furthermore, the valve seats are located on both sides of the valve ball.

[0007] Furthermore, the tank body connection end is connected to the connection end by a loose flange and bolts, with the loose flange fitted onto the connection end.

[0008] Furthermore, a connecting sleeve is fitted onto the bolt.

[0009] Furthermore, a valve stem is connected to the main valve body via a valve stem seal.

[0010] Furthermore, the packing gland is secured by a spring washer and a locking nut, which is threaded onto the valve stem.

[0011] Furthermore, the angle between the axis of the main valve body and the axis of the Y-shaped channel is 120°.

[0012] This utility model has a simple structure, ingenious design, and reasonable layout. It adopts a Y-shaped channel structure, which allows for online replacement of seals and reduces downtime losses. The main valve body adopts a 120° angled three-way flow channel design, which has a flat flow channel and low resistance, reducing media retention and preventing particulate materials from damaging the seal. It can quickly switch directions and quickly realize the functions of diversion and merging. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1 , 2 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] The three-piece three-way reversing tank bottom ball valve includes a main valve body 2. Both ends of the main valve body 2 are sealed and connected to a tank connection end 1 and a connection end 14 respectively via valve body seals 3. The tank connection end 1 and connection end 14 are connected by a slip-on flange 12 and bolts 13. The slip-on flange 12 is fitted onto the connection end 14. A valve seat 4 and a valve ball 5 are installed inside the main valve body 2. The valve seat 4 is located on both sides of the valve ball 5 to ensure stability under temperature changes or pressure fluctuations. A connecting sleeve 17 is fitted onto the bolt 13. For positioning, a valve stem 6 is connected to the main valve body 2 via a valve stem seal 11. A packing 9 is provided in the valve stem channel, and a packing gland 8 is installed on the packing 9. The packing gland 8 is fastened by a spring washer 10 and a locking nut 7 to ensure low leakage characteristics under normal and high temperature conditions. The locking nut 7 is threadedly connected to the valve stem 6. A Y-shaped channel 16 is welded to the main valve body 2. The angle between the axis of the main valve body 2 and the axis of the Y-shaped channel 16 is 120°. A loose flange 15 is fitted on the outside of the Y-shaped channel 16.

[0017] The principle of this utility model is that the tank connection end 1 is welded to the bottom of the pressure vessel. When the seal needs to be replaced or the valve needs maintenance, rotating the valve stem 6 will switch the valve direction and connect the Y-shaped channel 16. The valve can still be used normally without affecting the storage of the pressure vessel, reducing downtime losses. Furthermore, because the main valve body 2 adopts a 120° angled three-way flow channel design, the medium is forced to turn at the bend, generating violent turbulent diffusion, effectively reducing flow resistance and reducing medium retention in the flow channel, avoiding damage to the seal by particulate materials, avoiding secondary pollution, significantly reducing downstream energy dissipation pressure, and mitigating the risks of vibration and cavitation.

[0018] The embodiments described above are merely preferred embodiments of this utility model, and not all feasible embodiments of this utility model. For those skilled in the art, any obvious modifications made without departing from the principles and spirit of this utility model should be considered to be included within the scope of protection of the claims of this utility model. Although this utility model has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of this utility model. In particular, as long as there is no technical conflict, the features in the embodiments disclosed in this utility model can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, this utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
