[0022] See also Figure 1-5 , an embodiment provided by the utility model:
[0023] A valve rubber seat with good air tightness: comprising a valve seat body 1, a sealing ring 11 is placed on the surface of the valve seat body 1, a retaining ring 2 is fixedly connected to the surface of the valve seat body 1, a first spring 21 is fixedly connected to the surface of the valve seat body 1, a side pressure plate 22 is fixedly connected to the surface of the first spring 21, a guide rod 23 is fixedly connected to the surface of the side pressure plate 22, the guide rod 23 is slidably connected to the surface of the valve seat body 1, a first connecting ring 25 is plugged into the surface of the valve seat body 1, a second connecting ring 26 is plugged into the surface of the valve seat body 1, an extrusion plate 24 is fixedly connected to the surface of the first connecting ring 25, and the second connecting ring 26 is fixedly connected to the lower surface of the extrusion plate 24. The valve rubber seat can extrude the sealing ring 11 from two directions, thereby improving the use effect of the sealing ring 11 and ensuring its sealing performance.
[0024] Furthermore, an ejection mechanism is provided on the surface of the valve seat body 1, and the ejection mechanism includes a second spring 3, the second spring 3 is fixedly connected to the surface of the valve seat body 1, a push rod 31 is fixedly connected to the surface of the second spring 3, a connecting rod 32 is fixedly connected to the surface of the push rod 31, an operating ring 33 is fixedly connected to the surface of the connecting rod 32, and the push rod 31 is slidably connected to the surface of the valve seat body 1. After the sealing ring 11 is squeezed on the valve seat body 1 for a long time, it will be difficult to remove and replace it. The ejection mechanism can eject the sealing ring 11 from the valve seat body 1, thereby facilitating the rapid replacement of the sealing ring 11.
[0025] Furthermore, a sealing groove is provided on the surface of the valve seat body 1, an extrusion groove is provided on the surface of the valve seat body 1, the sealing ring 11 is placed on the sealing groove of the valve seat body 1, the first connecting ring 25 extrude the sealing ring 11 on the sealing groove of the valve seat body 1, thereby extruding the sealing ring 11 at the top of the valve seat body 1, and the second connecting ring 26 is inserted into the extrusion groove of the valve seat body 1, and the height of the second connecting ring 26 is greater than the height of the first connecting ring 25, so that the second connecting ring 26 enters the extrusion groove of the valve seat body 1 before the first connecting ring 25.
[0026] Furthermore, a guide hole is opened on the surface of the valve seat body 1, and the guide hole of the valve seat body 1 is connected to the sealing groove and the extrusion groove of the valve seat body 1. The guide rod 23 slides on the guide hole of the valve seat body 1. The side pressure plate 22 is in the shape of a tube sheet. The side pressure plates 22 are provided in multiple groups and are evenly arranged in a ring shape on the sealing groove of the valve seat body 1. The side pressure plates 22 squeeze the sealing ring 11 onto the retaining ring 2 from the side on the sealing groove of the valve seat body 1.
[0027] Furthermore, the side of the guide rod 23 away from the side pressure plate 22 is inclined, and the second connecting ring 26 contacts the inclined surface of the guide rod 23 on the extrusion groove of the valve seat body 1. The guide rod 23 drives the side pressure plate 22 to move on the sealing groove of the valve seat body 1 through the second connecting ring 26. The second connecting ring 26 squeezes multiple groups of guide rods 23 at the same time, so that multiple groups of side pressure plates 22 squeeze the sealing ring 11.
[0028] Furthermore, a guide hole is opened on the surface of the valve seat body 1, and the guide hole of the valve seat body 1 is in a "T" shape.

[0029] Furthermore, the second spring 3 is fixedly connected to the guide hole of the valve seat body 1, and the elastic force of the second spring 3 acts on the push rod 31 and the connecting rod 32. The operating ring 33 is annular in shape, and the operating ring 33 slides on the outer surface of the valve seat body 1. The operating ring 33 can drive multiple groups of connecting rods 32 to slide on the guide hole of the valve seat body 1, thereby allowing the multiple groups of push rods 31 to push the sealing ring 11 out of the sealing groove of the valve seat body 1.
[0030] Working principle: The first connecting ring 25 is inserted into the sealing groove of the valve seat body 1 through the extrusion plate 24, and the second connecting ring 26 is inserted into the extrusion groove of the valve seat body 1. The second connecting ring 26 will squeeze multiple sets of guide rods 23 on the extrusion groove, so that the multiple sets of guide rods 23 drive the side pressure plate 22 to slide on the sealing groove of the valve seat body 1. The side pressure plate 22 will deform the first spring 21, and the side pressure plate 22 will squeeze the sealing ring 11 on the side of the sealing groove of the valve seat body 1 on the retaining ring 2. At the same time, the first connecting ring 25 will also squeeze the sealing ring 11 above the sealing groove of the valve seat body 1, thereby expanding the extrusion direction of the sealing ring 11, improving the use effect of the sealing ring 11, and ensuring the sealing performance.
[0031] By sliding the operating ring 33 upward on the outer surface of the valve seat body 1, the operating ring 33 drives multiple sets of connecting rods 32 to slide on the guide holes of the valve seat body 1. The connecting rods 32 drive the push rods 31 to slide upward on the guide holes of the valve seat body 1 and cause the second spring 3 to deform. The push rods 31 will slide to the bottom of the sealing groove of the valve seat body 1, and the multiple sets of push rods 31 will push the sealing ring 11 out of the sealing groove of the valve seat body 1, making it convenient to replace the sealing ring 11.
