The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1-5, the present invention provides an embodiment: a ball valve comprises a shell 1, a ball body 8 arranged inside the shell 1, wherein the ball body 8 is connected with a valve rod 10; two ends of the shell 1 are connected with a connecting piece 7, the valve seat 4 is fixed inside the shell 1 through the connecting piece 7, and the valve seat 4 is extruded on the ball 8 through the connecting piece 7; the connecting piece 7 is provided with a first groove 6, and a sealing ring 5 is arranged inside the first groove 6.
In summary, since the connecting member 7 is connected to the housing 1, the valve seat 4 and the ball 8 are easily assembled into the housing 1, and the valve seat 4 can be tightly attached to the ball 8 by tightening the connecting member 7 and the housing 1, so as to enhance the sealing performance between the valve seat 4 and the ball 8; thirdly, the ball 8, the valve seat 4 and the sealing ring 5 are assembled into the shell 1 in sequence from one side of the shell 1.
In addition, because the connecting piece 7 is also provided with the first groove 6, and the sealing ring 5 is arranged in the first groove 6, after the connecting piece 7 is connected with the shell 1, the sealing ring 5 can be urged to cling to the valve seat 4, and the other surface of the valve seat 4 can be urged to cling to the ball 8, so that the sealing property between the valve seat 4 and the ball 8 is enhanced; meanwhile, the sealing ring 5 is arranged between the connecting piece 7 and the shell 1, so that the sealing between the shell 1 and the connecting piece 7 can be realized by the sealing ring 5, and the using number of sealing pieces is reduced.
Especially, because the sealing washer 5 is extruded after connecting piece 7 is fixed with casing 1, and the sealing washer 5 after the pressurized has elasticity, consequently can make lasting the laminating with spheroid 8 of disk seat 4, so can solve the problem that the seepage easily appears after disk seat 4 and spheroid 8 are used for a long time again.
In order to further optimize the overall structure of the device, a second groove 9 is further formed in the surface, facing the connecting piece 7, of the valve seat 4, the first groove 6 and the second groove 9 are identical in structure, due to the arrangement of the two grooves, the volume of the whole sealing ring 5 in the shell 1 is reduced, and meanwhile, the sealing ring 5 can be fixed from two sides of the sealing ring 5 through the two grooves.
Based on the above, the space occupied by the sealing ring 5 can be reduced, and meanwhile, the sealing ring 5 can be stably and reliably positioned in the equipment.
The shell 1 is also provided with a mounting hole 3; the mounting holes 3 are located above the ball body 8, the number of the mounting holes 3 is two, and the mounting holes 3 are connected with the bolts 2. Through the mode, take off two bolts 2 from casing 1, then pour into mounting hole 3 with the air supply in, the air supply is flowed out by another mounting hole 3 this moment, consequently can utilize the inside dust of air supply clearance casing 1 under the condition of not disassembling casing 1, and meanwhile, mounting hole 3 is convenient for the inside medium of casing 1 outwards to be drawn forth in the equipment use.
On the basis of the above scheme, since the ball 8 is provided with the slot 11 and the valve rod 10 is connected with the slot 11 in a matching manner through the plug 12, the ball 8 and the valve rod 10 can be assembled by inserting and pulling out, and therefore, the ball 8 can be further conveniently assembled into the housing 1 from one side of the housing 1.
Because the sphere 8 is also provided with the connecting part 13 and the slot 11 is arranged on the connecting part 13, the opening of the slot 11 does not affect the sphere 8; and secondly, the bearing capacity of the ball body 8 can be enhanced, and the problems that the ball body 8 is stressed unevenly and is easy to deform when the valve rod 10 rotates are avoided.
Furthermore, the cross sections of the plug 12 and the slot 11 are both cross-shaped, so that the transmission efficiency of the valve rod 10 is reliably ensured, and meanwhile, the problem of power transmission failure caused by falling off or slipping between the plug 12 and the slot 11 can be avoided.
Furthermore, because the surface of the sealing ring 5 facing the connecting piece 7 is further provided with the protrusion 14, and the sealing ring 5 and the protrusion 14 are of an integral structure, the elastic force of the sealing ring 5 can be enhanced by the protrusion 14, so that the acting force of the sealing ring 5 on the valve seat 4 can be enhanced, and meanwhile, the protrusion 14 can be attached to the first groove 6 by utilizing the reaction force of the valve seat 4 on the sealing ring 5, so as to enhance the sealing property between the shell 1 and the connecting piece 7.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
