Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a three-piece bottom ball valve that is easy to adjust in direction. Background Technology

[0002] In certain applications requiring high cleanliness and tightness, and where installation space is limited, the bottom valve of a pressure vessel cannot be installed with a straight-through pipe connection. Right-angle pipe connections can create dead angles in the valve cavity, leading to the accumulation of viscous or particulate media, necessitating frequent cleaning. Prolonged use can also cause internal leakage due to wear or crystallization, especially in highly corrosive media. Utility Model Content

[0003] To solve the above problems, this utility model provides a three-piece bottom ball valve that is easy to adjust in direction.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a three-piece tank bottom ball valve with easily adjustable direction, including a main valve body, one end of the main valve body is sealed to the tank body connection end, and the other end is sealed to the elbow pipe connection end. The angle between the central axis of the elbow pipe connection end and the central axis of the main valve body is an obtuse angle. Valve seats are provided on both sides of the main valve body. A valve ball and a valve stem are provided inside the main valve body. A valve stem seal, packing, packing gland, and spring washer are installed on the valve stem and are fastened by a locking nut.

[0005] Furthermore, the inner end of the elbow-type pipe connection is fitted with a slip-on flange, and bolts are threaded through the slip-on flange, the main valve body, and the tank body connection end in sequence.

[0006] Furthermore, the bolts are fitted with connecting sleeves.

[0007] Furthermore, the outer end of the bent pipe connection is fitted with a slip-on flange two, and the bent pipe connection is connected to the external pipe through the slip-on flange two.

[0008] Furthermore, one end of the main valve body is sealed to the tank connection end through a valve body seal, and the other end is sealed to the elbow-type pipe connection end through a valve body seal.

[0009] Furthermore, the locking nut is threadedly connected to the valve stem.

[0010] This utility model features a simple structure, ingenious design, and reasonable layout. The inlet end is welded to the bottom of the pressure vessel, while the outlet end adopts a bent pipe connection structure, which can be adapted to the spatial structure of the pressure vessel. Furthermore, the obtuse-angled flow channel design forces the medium to change direction at the bend, generating intense turbulent diffusion, effectively reducing flow resistance and minimizing medium stagnation in the flow channel, thus preventing particulate material from damaging the seal. The bend structure, with its collisions and swirling within the bend, dissipates a large amount of kinetic energy, significantly reducing downstream energy dissipation pressure and mitigating the risks of vibration and cavitation.

[0013] The following is in conjunction with the appendix Figure 1 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.

[0014] The easily adjustable three-piece tank bottom ball valve includes a main valve body 2. One end of the main valve body 2 is sealed to the tank connection end 1 via a valve body seal 3, and the other end is sealed to the elbow-type pipe connection end 14 via the valve body seal 3. The inner end of the elbow-type pipe connection end 14 is fitted with a slip-on flange 12. Bolts 13 pass through the slip-on flange 12, the main valve body 2, and the tank connection end 1 in sequence for threaded connection. A connecting sleeve is fitted around the bolts 13. The outer end of the elbow-type pipe connection end 14... The set includes a slip-on flange 2 15, and the elbow-type pipe connection end 14 is connected to the external pipe through the slip-on flange 2 15. The angle between the central axis of the elbow-type pipe connection end 14 and the central axis of the main valve body 2 is an obtuse angle. Valve seats 4 are provided on both sides of the main valve body 2. Valve ball 5 and valve stem 6 are provided inside the main valve body 2. Valve stem seal 11, packing 9, packing gland 8 and spring gasket 10 are installed on the valve stem 6 and are fastened by locking nut 7. The locking nut 7 is threadedly connected to the valve stem 6.

[0015] Tank connection end 1 is welded to the bottom of the pressure vessel. One end of the main valve body 2 is sealed to tank connection end 1 via valve body seal 3. The elbow-type pipe connection end 14 structure can be adapted to the spatial structure of the pressure vessel. Furthermore, the obtuse-angle flow channel design forces the medium to change direction at the bend, generating intense turbulent diffusion, effectively reducing flow resistance and media stagnation in the flow channel, preventing particulate material from damaging the seal. The elbow structure experiences collisions and swirling within the bend, consuming a large amount of kinetic energy, significantly reducing downstream energy dissipation pressure, and mitigating vibration and cavitation risks. With its simple structure, low manufacturing cost, smooth flow channel, and low resistance, it is suitable for ultra-large diameter and high-pressure applications, and has a long range, making it suitable for scenarios requiring the medium to be directed over long distances.
