Abstract
The utility model discloses a ball valve body which comprises a left valve body and a right valve body. The left valve body is provided with an annular connecting flange in a protruding mode, a plurality of left clamping teeth are evenly arranged on the connecting flange in the circumferential direction, the right valve body is provided with a clamping groove into which the connecting flange is embedded, and the clamping groove is provided with right clamping teeth abutting against the left clamping teeth in the axial direction. When the ball valve body is installed, the connecting flange aligns with the clamping groove, the connecting flange is embedded into the clamping groove, at that time, the left clamping teeth do not abut against the right clamping teeth, the connecting flange and the clamping groove rotate in the circumferential direction of a valve body channel by a certain degree to enable the left clamping teeth to abut against the right clamping teeth in the axial direction of the valve body channel, and then the left valve body and the right valve body are spliced together. The splicing process of the left valve body and the right valve body is similar to the splicing process of a pressure cooker body and a cooker cover. The operation is easy, and the installation process is easy and convenient.

For achieving the above object, the utility model provides following technological scheme: a kind of ball valve body, comprise left valve barrel and right valve barrel, on described left valve barrel, be equipped with annular flange connector, described flange connector is along being circumferentially evenly provided with some left latches, described right valve barrel is provided with the draw-in groove for chimeric flange connector, and described draw-in groove is provided with for the right latch with left latch axial direction butt.
By adopting technique scheme, when mounting ball valve valve body, flange connector is aimed to draw-in groove, make both mutually chimeric, now left latch and right latch do not connect, then along the valve channel several angle that rotates in a circumferential direction, left latch and right latch are connected along valve channel axial direction, can complete the splicing (this process is similar to the splicing of pressure cooker body and pot cover) of left valve barrel and right valve barrel, simple to operate, installation process is easy.
The utility model is further set to: one end of the relative right valve barrel of described left valve barrel is provided with limited part, described limited part is provided with the first conical surface, one end of the relative left valve barrel of described right valve barrel is provided with the defining flange matching with limited part, described defining flange is provided with the second conical surface, and described the first conical surface and the second conical surface are close to setting.
By adopting technique scheme, the cooperation of limited part and defining flange, play the effect of location, make left valve barrel and right valve barrel coordinate exactly formation passage, and when left valve barrel is closely connected with right valve barrel, the first conical surface and the second conical surface fit tightly, form inclined-plane sealing, further improve sealing, prevent that medium from leaking outside.
The utility model is further set to: in described draw-in groove, be provided with the first seal ring.
By adopting technique scheme, insufficient space in draw-in groove is to hold flange connector and the first seal ring, this makes by rotation, to make after left latch and right latch connect, the first seal ring is closely compressed among draw-in groove, be full of whole draw-in groove, improve the tightness connecting between left valve barrel and right valve barrel, improve sealing, prevent that medium from leaking outside.
The utility model is further set to: described left valve barrel and right valve barrel cooperation are provided with seal groove, are provided with the second seal ring in described seal groove.
By adopting technique scheme, between left valve barrel and right valve barrel, closely connect, the second seal ring is squeezed, make it be full of seal groove space, realize elastic packing, further improve sealing, prevent that medium from leaking outside.
The utility model is further set to: described left valve barrel and right valve barrel cooperation are provided with for preventing that left valve barrel is with respect to the positioning device of the circumferential rotation of right valve barrel.
By adopting technique scheme, after completing the splicing of left valve barrel and right valve barrel, by positioning device, prevent from occurring between the two again to rotate, and cause both to depart from, improve applicability and the stability of ball valve body.
