Detailed Description
The utility model is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention can be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope defined by the present application.
As shown in fig. 1-5, the main valve cover with good sealing performance of the present invention comprises: the valve cover comprises a valve cover main body 1, a connecting sleeve 2, a first sealing ring groove 4 and a second sealing ring groove 5; be connected with on the valve gap main part 1 the adapter sleeve 2, be provided with first sealed annular 4 on the 2 inner walls of adapter sleeve with the sealed annular 5 of second, first sealed annular 4 with all be provided with seal ring on the sealed annular 5 of second, 1 inside the setting of valve gap main part is hollow structure, be provided with internal thread 6 on the adapter sleeve 2, the surface of adapter sleeve 2 is provided with connecting thread 3, adapter sleeve 2 cooperation first sealed annular 4 with the sealed annular 5 of second is used for connecting the valve body, seal ring is used for improving the gas tightness that valve gap main part 1 and valve body are connected.
The leakproofness of current valve gap is relatively poor, and when the valve gap was connected with the valve body, gas or liquid might outwards reveal from the junction of valve gap and valve body to be unfavorable for the normal use of valve body. Based on this, this application provides a main valve gap that leakproofness is good, and the leakproofness is higher, and when the valve gap was connected with the valve body, gaseous or liquid can not outwards reveal from the junction of valve gap and valve body to be favorable to the normal use of valve body.
