The top of the water tank cover 12 is provided with a water injection pipe 14, the water injection pipe 14 is used for injecting water into the chamber 10 of the water tank 1, and a steam outlet 15 is provided at a side of the water injection pipe 14. The upper portion of the water injection pipe 14 is further provided with a cap 5 for covering an inlet of the water injection pipe, and the cap 5 is screw-coupled with the water injection pipe 14.
Please refer to fig. 2 to 5. According to the utility model discloses a steam engine prevent steam escape valve structure includes disk seat 3 and case 4.
The valve seat 3 is arranged in the water injection pipe 14 and is positioned above the steam outlet 15, the peripheral surface of the valve seat 3 is hermetically connected with the inner wall of the water injection pipe 14, and the valve seat 3 is provided with a water inlet 30. The valve body 4 includes a connecting portion 41 and a valve portion 42. The connection portion 41 is connected with the valve seat 3 and the valve piece portion 42, respectively, and the valve piece portion 42 is attached to the bottom of the valve seat 3 to close the water inlet 30.
In the present embodiment, the connecting portion 41 has a rod shape. The connecting portion 41 passes through the mounting hole 31 of the valve seat 3 and is fixedly mounted on the valve seat 3 in a manner such that the connecting portion 41 is in interference fit with the mounting hole 31. The lower end of the connection portion 41 is connected to the valve sheet portion 42. Further, the connecting portion 41 is provided with an annular projection 411 that projects in the radial direction, the outer diameter of the annular projection 411 is larger than the aperture of the mounting hole 31, and the annular projection 411 is located above the mounting hole 31.
In the present embodiment, the valve seat 3 includes an outer ring 3a and a support portion 3b provided inside the outer ring 3 a.
