Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an easy-to-disassemble horizontal three-way ball valve. Background Technology

[0002] In industrial production and fluid transport systems, three-way ball valves are widely used for controlling fluid flow direction, merging, and splitting. Traditional three-way ball valves mostly employ a two-seat structure. However, in scenarios with high requirements for sealing performance, flow control accuracy, and complex operating conditions, the two-seat structure reveals many limitations. For example, in high-pressure, high-velocity fluid media environments, the traditional two-seat structure struggles to guarantee good sealing performance, easily leading to leakage, resulting in media loss, environmental pollution, and potential safety risks.

[0003] With the continuous development of industrial technology, industries such as petrochemicals, natural gas transportation, and fine chemicals have placed more stringent demands on valve performance. In these industries, the fluid media often have characteristics such as corrosiveness, high viscosity, or the presence of solid particles. This requires valves not only to have reliable sealing performance but also to be able to adapt to complex media characteristics, ensure long-term stable operation, and be easy to maintain. Utility Model Content

[0004] To solve the above problems, this utility model provides an easy-to-disassemble horizontal three-way ball valve.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an easy-to-disassemble horizontal three-way ball valve, including a valve body, a valve ball is provided in the valve body, a main valve seat is provided at the top and bottom of the valve ball, a back valve seat is provided on both the left and right sides of the valve ball, a valve cover is installed on the top of the valve body, a valve seat support is installed inside the left side of the valve body, and a sealing cover is installed inside the right side of the valve body.

[0006] Furthermore, a valve cover is fixedly installed on the top of the valve body by bolts and nuts.

[0007] Furthermore, the valve body has an internal threaded connection on the left side with a valve seat support.

[0008] Furthermore, a cap is threaded onto the right side of the valve body.

[0009] Furthermore, the main valve seat located at the bottom of the valve ball is set in a groove in the valve body.

[0010] Furthermore, the main valve seat located at the top of the valve ball is set in a groove in the valve cover.

[0011] Furthermore, the back valve seat located on the left side of the valve ball is pressed into contact with the valve seat support.

[0012] Furthermore, the back valve seat located on the right side of the valve ball is pressed into contact with the cover.

[0013] This utility model uses a multi-seat structure, with each channel equipped with an independent sealing unit. Through the medium pressure self-tightening design, it ensures that non-working channels are completely cut off, greatly improving sealing reliability. The contact between the multi-seat and the ball is more uniform, which can disperse the impact force of medium scouring and particle wear, effectively extending the service life of the valve. At the same time, the multi-seat has a high degree of integration, and each valve seat can be disassembled and inspected independently during routine maintenance and inspection of its wear condition, without having to disassemble the entire pipeline system. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] The components are: 1. Valve body; 2. Main valve seat; 3. Back valve seat; 4. Valve ball; 5. Cover; 6. Valve cover; 7. Bolts and nuts; 8. Valve seat support. Detailed Implementation

[0016] 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.

[0017] This is an easily detachable horizontal three-way ball valve, comprising a valve body 1, a valve ball 4 housed within the valve body 1, main valve seats 2 located at both the top and bottom of the valve ball 4, and back valve seats 3 located on both the left and right sides of the valve ball 4. A valve cover 6 is fixedly mounted on the top of the valve body 1 by bolts and nuts 7. A valve seat support 8 is internally threaded onto the left side of the valve body 1, and a sealing cap 5 is internally threaded onto the right side of the valve body 1. The main valve seat 2 located at the bottom of the valve ball 4 is positioned within a groove in the valve body 1, and the main valve seat 2 located at the top of the valve ball 4 is positioned within a groove in the valve cover 6. The back valve seat 3 on the left side of the valve ball 4 is in close contact with the valve seat support 8, and the back valve seat 3 on the right side of the valve ball 4 is in close contact with the sealing cap 5.

[0018] This easy-to-disassemble horizontal three-way ball valve achieves flow path switching by rotating the ball 4: when the internal flow path of the ball 4 is aligned with the corresponding interface of the valve body 1, the medium can flow along the corresponding path (such as the top / bottom interface being connected to the left / right interface); by rotating the ball 4 (connected to the ball 4 shaft by an external actuator), its flow path is aligned with different interface combinations, thus switching the flow path of the medium (achieving three-way reversing function).

[0019] In terms of sealing, the main valve seat 2 at the top of the valve ball 4 is pressed by the valve cover 6, and the main valve seat 2 at the bottom is limited by the groove of the valve body 1, forming an axial seal by fitting with the surface of the valve ball 4; the back valve seat 3 on the left side of the valve ball 4 is pressed by the valve seat support 8, and the back valve seat 3 on the right side is pressed by the cover 5, forming a radial seal by fitting with the surface of the valve ball 4, together ensuring that there is no leakage of the medium during the flow or switching process.

[0020] 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.

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.
