Description

Technical Field

[0001] The present application relates to the field of pipeline valves, and in particular to a split angle valve. Background Art

[0002] Angle valve is a commonly used valve. Its structural feature is a 90-degree corner shape at the pipe connection. It is also called an angle stop valve or a triangular valve. It is a commonly used accessory in industrial systems and is installed between the pipe and the terminal equipment.

[0003] However, the valve core and valve seat of the angle valve are prone to corrosion and erosion due to the scouring of liquid during use. In the prior art, when the valve core of the commonly used one-piece angle valve is corroded and eroded, the valve shaft and valve core need to be replaced as a whole, and when the valve seat is corroded and eroded, the lower flange and valve seat need to be replaced as a whole. In this case, it will cause great material loss and increase production costs. Utility Model Content

[0004] In response to the above-mentioned problems, the present application provides a split angle valve, which can achieve targeted replacement of the valve core and valve seat when corrosion and erosion occur on the valve core and valve seat of the angle valve.

[0005] To achieve the purpose of this application, this application provides the following technical solutions:

[0006] In a first aspect, the present application provides a split angle valve, comprising: a pneumatic actuator, a valve shaft, a valve body, a valve seat, and a valve core;

[0007] One end of the valve shaft is connected to the output end of the pneumatic actuator, and the other end is detachably connected to the valve core via a first bolt;

[0008] The valve seat is detachably connected to the lower flange seat via a second bolt; the lower flange seat is fixedly connected to the valve body;

[0009] The valve core and the valve seat can be sealingly matched.

[0010] In a possible implementation manner, the first connecting surface between the valve shaft and the valve core is a conical surface.

[0011] In a possible implementation manner, the second connecting surface between the valve seat and the lower flange seat is a conical surface.

[0012] In a possible implementation, the split angle valve further includes: an upper flange seat, one end of which is fixedly connected to the lower flange seat by a connecting bolt, and the other end of which is fixedly connected to the pipeline.

[0013] In a possible implementation, the first bolt is a hexagon socket countersunk head.

[0014] In a possible implementation, the second bolt is any one or more of a hexagon socket head countersunk bolt and a hexagon socket head bolt.

[0015] In a possible implementation manner, the taper of the first connecting surface is 1:50.

[0016] In a possible implementation manner, the taper of the second connecting surface is 1:50.

[0017] In a possible implementation manner, a sealing gasket is further provided between the upper flange seat and the lower flange seat.

[0018] The split angle valve provided in the present application can replace the valve core or valve seat in a targeted manner when corrosion and erosion occur on the valve core and valve seat of the angle valve, without the need to replace large-sized components such as the associated valve shaft and lower flange seat, thereby greatly reducing production costs and facilitating operation.

[0023] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0025] Example 1

[0026] Figure 1-2 A split angle valve provided in the embodiment of the present application includes: a pneumatic actuator 1, a valve shaft 2, a valve body 6, a valve seat 8, and a valve core 9;

[0027] One end of the valve shaft 2 is connected to the output end of the pneumatic actuator 1, and the other end is detachably connected to the valve core 9 via a first bolt 10;

[0028] The valve seat 8 is detachably connected to the lower flange seat 5 via a second bolt 11; the lower flange seat 5 is fixedly connected to the valve body 6;

[0029] The valve core 9 and the valve seat 8 can be sealed together.

[0030] The pneumatic actuator 1 can control the valve shaft 2 to drive the valve core 9 to move up and down. When the valve core 9 moves downward to the maximum range, the valve core 9 is tightly sealed against the valve seat 8 to perform sealing.

[0031] In a possible implementation, the first connection surface between the valve shaft 2 and the valve core 9 is a conical surface. This implementation can ensure the coaxiality of the valve core 9 and the valve shaft 2.

[0032] In a possible implementation, the second connection surface between the valve seat 8 and the lower flange seat 5 is a conical surface. This implementation can ensure the coaxiality of the valve seat 8 and the lower flange seat 5.

[0033] In a possible implementation, the split angle valve further includes: an upper flange seat 4, one end of which is fixedly connected to the lower flange seat 5 via a connecting bolt 3, and the other end of which is fixedly connected to the pipeline.

[0034] In a possible implementation, the first bolt 10 is a hexagon socket countersunk head. This implementation enables the valve core 9 to fit tightly with the valve seat 8 .

[0035] In a possible implementation, the second bolt 11 is any one or more of a hexagon socket head countersunk bolt and a hexagon socket head bolt.

[0036] In a possible implementation, the taper of the first connecting surface is 1:50. This implementation can better ensure the coaxiality of the valve shaft 2 and the valve core 9.

[0037] In a possible implementation, the taper of the second connection surface is 1:50. This implementation can better ensure the coaxiality of the valve seat 8 and the lower flange seat 5.

[0038] In a possible implementation, a sealing gasket 7 is provided between the upper flange seat 4 and the lower flange seat 5. This implementation can ensure the sealing performance of the flange.

[0039] Working principle:

[0040] When corrosion and erosion occur on the valve core and valve seat of the split angle valve of the present application, the valve core and valve seat are disassembled in a targeted manner. When replacing the valve core 9, only the first bolt 10 needs to be removed for replacement. When replacing the valve seat 8, only the second bolt 11 needs to be removed for replacement.

[0041] In the several embodiments provided in the present application, it should be understood that the disclosed systems, modules and methods can be implemented in other ways. For example, the module embodiments described above are only schematic, for example, the division of units is only a logical function division, and there may be other division methods in actual implementation, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be an indirect coupling or communication connection through some interfaces, modules or units, which can be electrical, mechanical or other forms.

[0042] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, various changes and modifications made without departing from the concept of the present application should be deemed to belong to the protection scope of the present application.
