Example Embodiment
[0030] Example 1
[0031] like Figure 4 , Figure 5 , Image 6 The shown forged-welded valve body is a double-sided steam exhaust structure with medium outlet ends on the left and right sides. The flow channel structure of the valve body is as follows: from the medium inlet end on the lower side upward, through the side channels on the front and rear sides to enter the valve body In the middle cavity, when the steam is discharged, it flows downward from the middle through hole of the valve seat located on the lower side of the middle cavity of the valve body, and then flows to the left and right sides to the outlet end of the medium. Drain the upright exhaust pipe to a safe place.
[0032] The specific structure of this embodiment is as follows: the lower part of the forged welded valve body is the installation connection end of the valve, when the installation and connection mode of the valve is butt welding connection, the butt welding groove is processed at the lower en...
Example Embodiment
[0043] Embodiment 2
[0044] In the technical solution of the forged-welded valve body in this embodiment, only the specific implementation structure of the side plate (5) is different from that of the first embodiment, and the structures of other parts are not different. Therefore, this embodiment only applies to the side plate (5) part. The specific structure of the first embodiment will be discussed, and the rest of the same places as the first embodiment will not be described.
[0045] like Figure 9 and Figure 10 As shown, the inner surface of the side plate (5) and the inner surface of the side plate (5) in the first embodiment are only a simple middle plane plus the cylindrical surfaces on the lower two sides. The difference is that the inner surface is concave, the concave The middle part is also composed of a middle plane and a cylindrical surface that is connected to the upper and lower sides and curved inwardly. 5) The inner surface is formed by scanning a strai...
