For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can also be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Embodiment 1

[0023] Referring to Figures 1 to 4 As shown, a stainless steel valve body for a flush valve includes a left half shell 1 and a right half shell 2. The left half shell 1 and the right half shell 2 are laser welded to form a water valve body 3. The water valve body 3 is provided with an inlet 30, an outlet 31, and a valve core mounting port 32. A cavity 33 is provided inside the water valve body 3. An active core 4 is provided in the cavity 33 and is hermetically connected to the inner wall of the water valve body 3. Specifically, laser welding can be used to fix the active core 4 to the inner wall of the water valve body 3 to achieve water tightness. A valve core positioning platform 40 corresponding to the position of the valve core mounting port 32 is provided on one side of the active core 4. The valve core positioning platform 40 is formed by being concave inward on one side of the active core 4. A through hole 41 communicating with one end of the active core 4 is provided on the valve core positioning platform 40.

[0024] It should be noted that the active core 4 is tubular, with one end being a closed end and the other end being an open end. The open end of the active core 4 is in the same direction as the outlet 31, and the closed end of the active core 4 is in the same direction as the inlet 30, so that the fluid enters from the inlet, first passes through the valve core to control the water outlet, then enters the interior of the active core through the through hole 41, and finally flows out from the open end of the active core 4 to the outlet.

[0025] It should also be noted that a limiting ring 42 is provided along the circumferential direction at one end of the active core 4. The limiting ring 42 presses against the edge of the outlet end, playing a role in positioning and limiting the active core.

[0026] In order to ensure the water tightness after the connection between the movable core 4 and the water valve body 3, the edges at both ends of the movable core 4 and the inner wall of the water valve body 3 are fixed by laser welding, which can also prevent the fluid between the water inlet and the water outlet from being directly connected without passing through the control of the valve core, resulting in the valve core being unable to cut off the flow.

[0027] In this embodiment, the water valve body 3 is used in a quick-opening flush valve. Embodiment 2

[0028] As Figure 4 and Figure 5 shown, the water valve body 3 is further provided with a valve stem installation port coaxial with the valve core installation port 34. The movable core 4 is correspondingly provided with an installation hole 43 for the valve stem to pass through on one side of the valve stem installation port. The installation hole 43 and the through hole 41 are coaxial. The water valve body in this embodiment is used in a time-delay valve.

[0029] Compared with the prior art, the present invention has the following advantages and beneficial effects: The present invention adopts a stainless steel water valve body welded by a left half shell and a right half shell, and a movable core is hermetically connected inside the water valve body so that the valve core can be fixed in the valve core installation port, thereby being able to control the fluid cut-off and regulation. The stainless steel valve body is not only environmentally friendly and low-cost, but also not bulky and is more convenient to use.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
