Detailed Description
The leakage-proof switch valve of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-2, the anti-leakage switch valve of the present embodiment includes an actuator cylinder 1, a valve cover 2, a valve core 3, a valve rod 4, a valve seat 5 and a valve body 6; the device is characterized in that the actuating mechanism cylinder 1 is fixedly connected with the valve cover 2 through a bolt; a guide ring 7 is arranged in the actuating mechanism cylinder 1, and a matched adjusting block 8 is arranged in the guide ring 7 in a sliding manner; a fixing step 9 is arranged on the valve rod 4, and one end of the valve rod 4 penetrates through the adjusting block 8 and then is fixed on the adjusting block 8 through the matching of a bolt and the fixing step 9; the valve body 6 is provided with a valve seat 5, and the valve seat 5 is provided with a sleeve 10; the valve body 6 is fixedly connected with the valve cover 2 through bolts; one end of the valve rod 4 penetrates through the valve cover 2 and then is provided with a valve core 3; a plurality of sealing packing 11 are arranged between the valve rod 4 and the valve cover 2; the valve cover 2 is also provided with a detection port 12; two air vents 13 are also arranged on the actuating mechanism cylinder 1.
In the use process of the embodiment, the vent hole 13 on the actuating mechanism cylinder 1 is connected with an external air source, when the air source supplies air to the vent hole 13 on the upper part of the actuating mechanism cylinder 1, the air pressure on the upper part of the adjusting block 8 is greater than the air pressure on the lower part, so that the adjusting block 8 is pushed to move upwards and downwards along the guide ring 7, the valve rod 4 and the valve core 3 are driven to move downwards until the valve core 3 is in contact with the valve seat 5 for sealing, and the valve is closed; when the valve is opened, the air source supplies air to the air vent 13 at the lower part of the actuating mechanism cylinder 1, so that the air pressure at the lower part of the adjusting block 8 is larger than the air pressure at the upper part, the adjusting block 8 is pushed to move upwards through the air pressure, and the valve rod 4 and the valve core 3 are driven to move upwards at the same time, so that the valve is opened.
The beneficial effects of the utility model are that, the valve rod 4 is directly connected with the adjusting block 8 in the actuating mechanism cylinder 1, the actuating mechanism cylinder 1 is directly fixedly connected with the valve cover 2, the original middle bracket and transmission part are saved, when the sealing packing 11 arranged between the valve rod 4 and the valve cover 2 has a problem in sealing performance, the medium leaks through the valve rod 4, and only flows into the actuating mechanism cylinder 1, but does not leak; the detection port 12 is provided in the bonnet 2, and whether or not a leak occurs between the valve stem 4 and the packing material 11 can be detected through the detection port 12.
The scope of the present invention is not limited to the above embodiments and their variations. The present invention is not limited to the above embodiments, and other modifications and substitutions may be made by those skilled in the art.
