Detailed Description
Examples
The blowdown valve for the special vehicle of the embodiment, as shown in fig. 1, 2 and 3, includes: a valve body 2 and a valve cover 4 matched with the valve body 2. The valve cover 4 is installed on the valve body 2 through a first connecting rod 9, and the first connecting rod 9 is hinged on the valve body 2. A fixed support 8 extends on the valve body; the fixed support 8 carries one end of the main shaft 3, the main shaft 3 is connected with the valve cover 2 through a second connecting rod, the other end of the main shaft 3 is carried by the positioning plate 11, and the rotation of the main shaft 3 is operated by a handle 12 arranged at the other end of the main shaft 3. The rotation of the main shaft 3 drives the valve cover 4 to open or close through the second connecting rod.
The handle 12 is sleeved on the main shaft 3 through a sleeving part; the top end of the sheathing part is provided with a plug 15 matched with the sheathing part; the plug 15 is fixedly connected with the main shaft 3, and a torque spring 14 is arranged in the sleeving part; two ends of the torque spring 14 are respectively arranged on the sleeving part and the plug 15; the torsion spring 14 has a biasing force for rotating the main shaft 3 in a direction to close the valve cover 4.
The handle 12 is provided with a positioning pin 13, the positioning plate 11 is provided with a hole corresponding to the positioning pin 13, and the positioning pin 13 is matched with the positioning plate 11 to lock the handle 12.
