Detailed Description
The utility model is further described below with reference to the accompanying drawings:
referring to fig. 1-2: the vacuum baffle valve comprises a valve body 1, an upper valve cover 2, a lower valve cover 3 and a valve rod 4, wherein the upper valve cover 2 and the lower valve cover 3 are fixedly installed on the valve body 1, the valve rod 4 is in threaded connection with a screw hole 5 formed in the upper valve cover 2, the valve rod 4 is in sliding connection with a mounting through hole 6 formed in the lower valve cover 3, a sealing assembly is arranged between the valve rod 4 and the mounting through hole 6, a hand wheel 7 and a valve core 8 are respectively arranged at the upper end and the lower end of the valve rod 4, a mounting hole 9 is formed in the bottom of the hand wheel 7, the mounting hole 9 is in clearance fit with the valve rod 4, an inner hexagon socket sleeve 10 is fixedly installed in the mounting hole 9, a supporting spring 11 is arranged between the inner hexagon socket sleeve 10 and the valve rod 4, an outer hexagon head 12 which is matched with the inner hexagon socket sleeve 10 is arranged at the upper end of the valve rod 4, a plug 13 is arranged on the outer hexagon head 12, an annular clamping groove 14 is formed in the plug 13, a jack 15 is formed in the top of the hand wheel 7, the jack 15 can be in plug fit with the plug 13, an elastic clamping groove 16 is fixedly installed in the jack 15, and an elastic clamping groove 16 can be matched with the annular clamping ring 14.
The working principle of the utility model is as follows: when a vacuum baffle valve is required to be used for operation, the hand wheel 7 is pressed onto the valve rod 4, at the moment, the supporting spring 11 is compressed, the inner hexagonal hole of the inner hexagonal sleeve 10 is sleeved with the outer hexagonal head 12, meanwhile, the plug 13 is inserted into the jack 15, after the plug is inserted to the bottom, the elastic clamping ring 16 is elastically deformed and clamped into the annular clamping groove 14, positioning is realized, the friction force between the plug 13 and the jack 15 is improved, the hand wheel 7 is prevented from bouncing, and as the valve rod 4 is in threaded connection with the upper valve cover 2, the valve rod 4 moves up and down only through clockwise rotation of the hand wheel 7, so that the valve core 8 at the bottom of the valve rod 4 is closed and opened in the valve body 1; if the operation of the vacuum baffle valve is finished, at the moment, the inner hexagon sleeve 10 and the outer hexagon 12 can be separated only by pulling up the hand wheel 7, so that the hand wheel 7 is separated from the valve rod 4, and misoperation of an operator is prevented.
The sealing assembly comprises a tubular sealing ring 17 and a gland 18, wherein the gland 18 is positioned on the upper side of the lower valve cover 3, and a belleville spring 19 is arranged between the gland 18 and the upper valve cover 2. After the upper valve cover 2 is fixedly arranged on the valve body 1, the belleville spring 19 is compressed to generate elastic deformation, and the elastic force on the belleville spring 19 can push the gland 18 to press the tubular sealing ring 17 down, so that the sealing effect is improved.
The bottom bolt of lower valve gap 3 is connected with clamping ring 20, and fixed mounting has first sealing washer 21 on the outer lane of clamping ring 20, and fixed mounting has second sealing washer 22 between clamping ring 20 and the lower valve gap 3.
