Detailed Description
In order to make the technical solution of the present invention more apparent, the present invention is further described in detail with reference to the following examples, and it should be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.
Referring to the attached drawings 1-2, the utility model discloses a soft sealing ball valve with good sealing performance, which comprises a shell 1 and a valve body 2, wherein the middle part of the shell 1 is provided with a space for accommodating the valve body 2, the valve body 2 is arranged in the space, two sides of the shell 1 are provided with water through holes 3, the middle part of the valve body 2 is provided with a water through hole 4, the upper side of the valve body 2 is provided with a driving rod 5, the driving rod 5 passes through the shell 1 and is connected with a handle 6, two sides of the shell 1 are provided with a sealing device and a connecting pipe 7, the connecting pipe 7 is provided with an accommodating groove 8, the sealing device comprises a sealing ring 9 and a sealing sleeve 10, the sealing sleeve 10 is arranged in the accommodating groove 8, the sealing ring 9 is arranged between the sealing sleeve 10 and the shell 1 and supports against the outer ring of the water through hole, the limit bolt 12 penetrates through the limit hole and abuts against the inclined surface 11, and when the limit bolt 12 moves downwards, the sealing sleeve 10 pushes the sealing ring 9 to move towards the shell 1.
Novel structure's ball pump, through sealing washer 9 effectually prevented that rivers can be normal from the water channel flow of predetermineeing, can not spill over, and, after the time that the ball pump used is too long, loose condition can appear in sealing washer 9, at this moment, direct operation limit bolt 12 moves down, promote on sealing washer 9 removes and withstands shell 1, carry out sealed regulation, the life of ball pump has been guaranteed, of course, the change of sealing washer 9 is also very simple, loosen limit bolt 12 after, unpack connecting pipe 7 apart earlier, later take out sealing washer 9 can, do not set up a plurality of bolted connection, holistic simple structure has been guaranteed.
