Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.
Referring to fig. 1-4, the present invention provides a plug valve structure, which comprises a valve body 3, a valve rod 2 and a liquid-proof agent. The first end of the valve stem 2 is inserted into the valve body 3, the second end extends out of the valve body 3, and the second end of the valve stem 2 is provided with a boss 22. The liquid-proof member 1 comprises a sealing structure and a flow guide part 11 arranged on the lower side of the sealing structure, the sealing structure is coated on the outer side of the boss 22, and the sealing structure is provided with a liquid outlet 1211.
The utility model provides a plug valve structure is through setting up out liquid hole 1211 on seal structure to make the liquid of infiltration seal structure can avoid liquid to continue to stretch into valve body 3 along valve rod 2 in the play of liquid hole 1211 discharge, further guaranteed plug valve structure's sealed effect.
Optionally, a first groove 23 is formed on the upper side of the boss 22, a second groove 21 is formed on the lower side of the boss 22, the sealing structure includes a first sealing part 121 and a second sealing part 122, the second sealing part 122 covers the groove wall of the first groove 23 and is arranged in interference fit with the first groove 23, so as to improve the sealing effect between the second sealing part 122 and the first groove 23, the first sealing part 121 covers the boss 22 and is arranged in interference fit with the boss 22, and then the sealing effect between the first sealing part 121 and the boss 22 is improved.
Optionally, the liquid outlet 1211 is opened on the first sealing part 121 to discharge the liquid permeated through the second sealing part 122, thereby achieving the double liquid-proof effect.
