Abstract
A rubber sealing ball valve mainly solves the problems that a sealing ring of an existing traditional valve seat is made of hard plastics, sealing is difficult, a ball body can be abraded easily, and due to the fact that sealing materials of the valve seat are abraded, the ball body and the metal valve seat are in direct contact, the ball body is abraded by the metal valve seat, a valve seal leaks, and accidents are caused. The rubber sealing ball valve is characterized in that sealing ring mounting grooves (51) are formed in opposite faces of a valve seat (2) and a ball body (3), stop ring mounting grooves (61) are formed in the outer sides of the sealing ring mounting grooves (51), sealing rings (5) matched with the sealing ring mounting grooves (51) are arranged in the sealing ring mounting grooves (51), and stop rings (6) matched with the stop ring mounting grooves (61) are arranged in the stop ring mounting grooves (6). Under the condition that the valve seat sealing rings are abraded, the ball body is in contact with the stop rings, direct contact of the ball body and the metal valve seat is avoided, ball body abrasion is reduced, and service life is prolonged.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: if Fig. 1 is in conjunction with as shown in Fig. 2 to 3, in the utility model, a kind of rubber sealed ball valve, comprise valve body 1 and be located at valve seat 2 and the spheroid 3 in valve body 1, described valve seat 2 is between valve body 1 and spheroid 3, between described valve seat 2 and valve body 1, be provided with Regulation spring 4, described valve seat 2 is provided with seal ring mounting groove 51 with spheroid 3 opposing sides, described seal ring mounting groove 51 outsides are provided with back-up ring mounting groove 61, 51 li of described seal ring mounting grooves are provided with the seal ring 5 with seal ring mounting groove 51 adaptations, described back-up ring mounting groove 61 is provided with the back-up ring 6 with back-up ring mounting groove 61 adaptations.The situation lower sphere of valve seat insert wearing and tearing contacts with back-up ring, has avoided spheroid directly to contact with metal seat valve, reduces spheroid wearing and tearing, increases and uses.
In the utility model, as shown in the figure, seal ring mounting groove 51 cross sections are triangle, and described back-up ring mounting groove 61 cross sections are trapezoidal.Described seal ring and back-up ring can be filled in corresponding mounting groove, and the position of the installation of back-up ring is between seal ring and valve seat metal covering, after ring wear.Ball seal face contacts with back-up ring rather than valve body, has protected valve body surface, prevents scratch valve body.
In the utility model, as shown in the figure, described seal ring 5 and back-up ring 6 are made for explosion-proof type fluorine-containing rubber, and explosion-proof fluorine rubber can guarantee Security.
In the utility model, as shown in the figure, described valve seat is provided with Regulation spring mounting groove, and described Regulation spring 4 is located in Regulation spring mounting groove.Described Regulation spring 4 is made by stainless steel.Stainless steel spring conductive capability can guarantee by force the conduction between the metal parts (as valve body, spheroid) to having been completely cut off by plastics or rubber seal, effectively prevents static, and meanwhile, stainless steel spring also has stronger decay resistance.
In the utility model, as shown in the figure, described valve seat 2 comprises upstream valve seat 21 and downstream valve seat 22, described upstream valve seat 21 comprises upstream valve seat first step face, upstream valve seat second step face and upstream valve seat the 3rd step surface, described upstream valve seat second step face 212 is provided with upstream valve seat insert mounting groove, in described upstream valve seat insert mounting groove, is provided with upstream valve seat insert 213; Described downstream valve seat 22 comprises downstream valve seat first step face, downstream valve seat second step face and downstream valve seat the 3rd step surface, between described downstream valve seat the 3rd step surface 223 and valve body 1, form downstream valve seat insert mounting groove, in described downstream valve seat insert mounting groove, be provided with downstream valve seat insert 224.Upstream extremity is adopted single piston effect, and in valve, cavity pressure surpasses 1.33 times of valve rated pressure, the pressure of lumen can be automatically upstream valve seat can release; Tract downstream valve seat insert and downstream valve seat insert mounting groove form the second piston effect, if leaking appears in upstream valve seat, downstream double-piston effect valve seat is pushed spheroid to valve seat under the effect of middle cavity pressure, realize secondary and turn-off enhanced leaktightness effect.Such ball valve of structure has two sealings to turn-off, the superpressure of automatically releasing again; The two combination, sealability is strong; But while installing, by flowing to board, install, otherwise do not reach having a double meaning disconnected effect.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection scope of the present invention.
