[0022] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the present application.

[0023] In addition, in the description of the present application, it needs to be understood that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0024] In the present application, unless specifically defined and limited otherwise, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection, or communication; it can be directly connected, or indirectly connected through intermediate medium, or internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] In the present application, unless specifically defined and limited otherwise, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through intermediate medium. In the description of the specification, the description of the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0026] As shown in Figure 1 and Figure 2 The present application provides a corner seat valve with a dual-purpose connector 11, which comprises a corner seat valve body 10 and a connector 11 arranged at the bottom of the corner seat valve body 10. The connector 11 is internally provided with a socket weld 12 and a threaded interface 13. The inner wall diameter of the threaded interface 13 is smaller than that of the socket weld 12. The socket weld 12 is the first end of the connector 11, and the threaded interface 13 has a spacing between the socket weld 12.

[0027] As shown in the drawings, the structure of the corner seat valve body 10 is similar to that of the prior art, and asFigure 1 As shown in the figure, the first end of the threaded interface 13 is provided with a relief guide corner 14 at the junction with the inner wall of the socket weld 12.

[0028] It can be understood that, since the socket weld 12 and the threaded interface 13 are both arranged inside the connecting head 11, the user can choose two different connection modes of welding or threaded connection according to actual needs, thereby improving the flexibility and applicability of the connection; and the first end of the threaded interface 13 is provided with a relief guide corner 14 at the junction with the inner wall of the socket weld 12, which helps to avoid the molten pool from contacting the threads during welding, thereby protecting the threads from being damaged and facilitating the welding operation.

[0029] As a preferred embodiment of the present application, as shown in the figure, Figure 2 The angle seat valve further comprises an auxiliary connecting tool 15, which comprises a connecting pipe 16 and a plug-in head 17, the plug-in head 17 comprising a socket head 171, a threaded head 172 and a positioning pipe 173, and the plug-in head 17 being adapted to the connecting head 11.

[0030] It can be understood that, since part of the installation site or part of the manufacturers may not have prepared a pipe structure with a suitable diameter when using the angle seat valve, the auxiliary connecting tool 15 provided additionally in the present application can be connected with the pipe on site to enable the structure on site to be connected with the connecting head 11 of the angle seat valve more conveniently.

[0031] Furthermore, the arrangement of the auxiliary connecting tool 15 can also make the installation and disassembly of the angle seat valve more convenient, thereby reducing the installation time and labor intensity; in addition, when disassembling, even if the girth welding mode is adopted, the damaged part after disassembly is only the auxiliary connecting tool 15, which will not cause damage to the connected pipe, and when reconnection is needed, only the auxiliary connecting tool 15 needs to be assembled again, and subsequent assembly can be carried out, thereby making the use more convenient.

[0032] As a preferred embodiment of the present application, as shown in the figure, Figure 2 The diameter of the threaded head 172 is smaller than that of the socket head 171, the position of the threaded head 172 is higher than that of the socket head 171, and the threaded head 172 is threadedly matched with the threaded interface 13.

[0033] It should be noted that this arrangement is to adapt to the socket weld 12 and the threaded interface 13 of the connecting head 11, and facilitate the connection of the two, and the diameter of the threaded head 172 is smaller than that of the socket head 171, and the position of the threaded head 172 is higher than that of the socket head 171, which can ensure that the threaded connection does not interfere with the socket weld 12, and facilitates identification and operation.

[0034] Further, as shown in the figure, Figure 2As shown, the diameter of the positioning tube 173 is matched with the outer sidewall of the connecting head 11, the connecting head 11 can be inserted into the positioning tube 173, and the inner wall of the positioning tube 173 and the socket head 171 have a setting groove 19 therebetween.

[0035] The structure of the setting groove 19 is such that the cross section between the inner wall of the positioning tube 173 and the socket head 171 forms a structure similar to a trident, which facilitates the insertion of the positioning tube 173 into the connecting head 11, and the cooperation between the inner wall of the positioning tube 173 and the outer wall of the connecting head 11 facilitates the subsequent ring seam welding work, and the structure is simple and convenient to position.

[0036] Optionally, in order to further improve the installation effect and sealing effect, a flexible sealing ring 18 can be arranged on the inner bottom wall of the setting groove 19, so that the connecting head 11 can be connected more tightly when cooperating with the positioning tube 173, and the sealing effect is better.

[0037] In addition, the two sides of the connecting pipe 16 are respectively connected to the plug head 17 and the pipe structure. As for the connection mode of the connecting pipe 16 and the pipe structure, the present application is not limited, as long as the external pipe structure can be connected to the auxiliary connecting tool 15 through the connecting pipe 16, and a sufficient sealing effect is guaranteed, and the present application can be adopted.

[0038] The places not mentioned in the present application can be realized by using or referring to the existing technology.

[0039] Each embodiment in the present specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0040] The above only describes the embodiments of the present application and does not limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the scope of claims of the present application.
