Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1-3, a valve port sealing structure includes a valve body 1, a valve cover disposed on the valve body 1, a water inlet channel 2 and a water outlet channel opened on the valve body 1, a valve plate disposed between the water inlet channel 2 and the water outlet channel, and a valve rod for opening and closing the valve plate, where the ends of the valve body 1 located at the water inlet channel 2 and the water outlet channel are respectively provided with a sealing ring 8, the valve body 1 is provided with a pushing pipe 3 for pushing the sealing ring 8 against an external pipeline, the valve body 1 is provided with a pushing channel 9, the sealing ring 8 is disposed in the pushing channel 9, the pushing pipe 3 is slidably disposed in the pushing channel 9, one end of the pushing pipe 3 is abutted against the sealing ring 8, the other end of the pushing pipe 3 is provided with a pushing block 4 for pushing the pushing pipe 3 to slide transversely so as to push the sealing ring 8 against the external pipeline, the end of the pushing pipe 3 located inside the valve body 1 is fixedly provided with a water passing seat 31, the water passing seat 31 is provided with a fluid channel for passing fluid, the pushing block 4 is fixedly provided with a pushing block 31, the pushing block 4 is provided with a pushing block 5, and a second screw rod 5 is disposed on the pushing block 1, and a second screw rod 5 is disposed on the pushing block 5, and a second screw rod 5 for driving the pushing block 5, and a screw rod 5 is disposed on the valve body, and a screw rod 5 for driving the second screw rod 5.
In order to enable the sealing ring 8 to be further tightly pressed on the external pipeline when the sealing ring 8 is loosened, a plurality of springs 10 are arranged between the pressing pipe 3 and the sealing ring 8, one end of each spring 10 is connected with the sealing ring 8, and the other end of each spring 10 is connected with the pressing pipe 3.
In order to rotate the external screw 6 conveniently, a rotating handle 7 is arranged on the screw 6, and the rotating handle 7 is positioned outside the valve body 1.
The working principle is as follows:
after the valve is connected with an external pipeline, the screw 6 is rotated to rotate downwards to drive the fixed block 5 to move downwards, the first inclined surface 51 of the fixed block 5 and the second inclined surface 41 of the pushing block 4 resist against each other, so that the pushing block 4 is pushed to move towards the external pipeline, the pushing pipe 3 is driven to slide towards the external pipeline, at the moment, the pushing pipe 3 pushes the spring 10, the spring 10 elastically deforms, the sealing ring 8 is pushed to press against the external pipeline, only the sealing ring 8 is pushed against the external pipeline, the sealing ring 8 is pushed to be tighter along with the downward movement of the screw 6, and the sealing performance is better.
