Preferably, be provided with spring between described valve seat and the described valve body and realize floating of valve seat.
Preferably, be provided with seal ring in the described valve seat.
Preferably, the flange junction surface of described left and right valve body and described center valve body is provided with circumferentially and radial seal.
Preferably, be provided with stem packing between described valve rod and the described valve body, described stem packing is a fabricated structure, its top adopts a Gland to be fixed in described valve body, being provided with spring below described filler compensates and the effect of exerting pressure automatically realizing, also being provided with the sealing ring that is sheathed on the described valve rod below the described spring, be equipped with O-ring seals on the interior external diameter of described sealing ring.
Preferably, described fast-opening blind seat is integrally formed by described intervening valve body wall.
Compared with prior art, the utility model pigging ball valve directly is provided with a fast-opening blind seat and a fast-opening blind wherein removably is installed on valve body, valve body can be in communication with the outside under current floe condition and after removing fast-opening blind, and wiper directly can be placed the valve body chamber to carry out pigging, pigging finishes, and after wiper takes out from the fast-opening blind seat, installs fast-opening blind, rotating valve spheroid, can realize the through-flow of pipeline, so pigging is easy to operate, safe and reliable.

Fig. 2 is the partial cutaway diagrammatic sketch of pigging ball valve shown in Figure 1 perpendicular to the pipeline direction;
Fig. 3 is the partial enlarged drawing of I part among Fig. 1;
Fig. 4 is the partial enlarged drawing of II part among Fig. 1; And
Fig. 5 is the partial enlarged drawing of III part among Fig. 1.
Embodiment
As shown in Figure 1, the valve body 1 of the utility model pigging ball valve is a 3 stops, comprise left valve barrel 1.1, center valve body 1.2 and right valve barrel 1.3, be provided with valve sphere 2 in the valve body, valve sphere is supported by valve rod 3 about in the of 2 and adopts flat key to connect, and the drive unit by valve rod drives rotation, and this drive unit can be a turbine box mechanism 4.Valve sphere rotates 90 degree, gets final product throttle down, cuts off the pipeline medium.The valve sphere channel diameter is designed to identical with pipeline diameter, can make flow resistance little like this, and negotiability is big.The valve seat 5 that cooperates with valve body is floating type, can rely on pressure medium and area difference to reach the effect of two way sealed, shown in the partial enlarged drawing of Fig. 3, when the A cavity pressure is higher than the L chamber, the pressure that the area difference of D0 and Dm forms makes valve seat 5 compress valve sphere 2 and seals, opposite when the L cavity pressure is higher than the A chamber, the pressure that the area difference of Dm and D1 forms makes valve seat 5 compress valve sphere and seals.In addition, be provided with seal ring 6 in the valve seat 5, when breaking out of fire and during scaling loss seal ring 6, two metal coverings of valve seat 5 and valve sphere 2 can directly contact and form sealing surface to keep sealing, prevent that fire from stretching.Simultaneously, also be provided with spring 7 between valve seat 5 and the valve body 1, valve sphere 2 can be realized good conducting with valve body 1, valve rod 3 by spring 7 with valve body 1 like this, derives static effectively.
Again as shown in Figure 4, it shown in the figure partial enlarged drawing of II part among Fig. 1, the right valve barrel 1.3 of this pigging ball valve adopts circumferentially and double seal radially with the flange junction surface of center valve body 1.2, radial seal 8 adopts high temperature resistant graphite material to make, circumferential seal 9 is O shape rubber rings, thereby keeps excellent sealing performance with each valve body junction surface.Though the sealing configuration of right valve barrel shown in Fig. 4 and center valve body joint, left valve barrel 1.1 also adopts identical double sealing structure with the flange junction surface of center valve body 1.2, does not describe in detail at this.
Further referring to shown in Figure 5, it shown in the figure partial enlarged drawing of III part among Fig. 1, show the sealing configuration between valve rod 3 and the valve body 1, promptly adopt stem packing 10, this stem packing 10 is a fabricated structure, its top is adopted Gland 11 to be fixed in valve body 1 and is compressed, being provided with spring 12 below filler 10 compensates and the effect of exerting pressure automatically realizing, also be provided with the sealing ring 13 that is sheathed on the valve rod 3 below the spring 12, be equipped with O-ring seals 14 on the interior external diameter of sealing ring 13, make the stem packing sealing more reliable.
In the utility model, be formed with a fast-opening blind seat 1.21 on the direction perpendicular to pipeline on center valve body 1.2 walls, this fast-opening blind seat 1.21 is communicated with center valve body 1.2 inner chambers.In the present embodiment, the fast-opening blind seat is integrally formed by center valve body 1.2 walls.Fast-opening blind 14 is removably installed on this fast-opening blind seat 1.21.
During normal fed sheet of a media, the valve sphere passage is consistent with valve channel, and fast-opening blind is installed on the fast-opening blind seat, as shown in Figure 2.When needing pigging, valve sphere revolves and turn 90 degrees, and valve sphere passage and fast-opening blind seated connection are logical, and this moment, passage dammed, and fast-opening blind is removed from seat, and wiper is packed in the valve pocket of pigging ball valve, can carry out pigging work.After pigging finishes, wiper is taken out from the pigging ball valve, install fast-opening blind, valve sphere is revolved turn 90 degrees, it is through-flow to recover pipeline.
By pigging ball valve of the present utility model, can when pipeline is dammed, realize the emission and the recovery of wiper, and avoid adopting other auxiliary pipe cleaning device, make things convenient for the pigging operation, and safe and reliable.
