Abstract
The utility model discloses a tank bottom ball valve which comprises a valve body. A ball containing cavity is formed in the valve body, the inner portion of the ball containing cavity is provided with a tetrafluoroethylene lining, and the tetrafluoroethylene lining is provided with a feed port and a discharge port. The tank bottom ball valve is characterized in that a ball is wrapped by the tetrafluoroethylene lining tightly, and all the space in the containing cavity, except for the ball, the feed port and the discharge port is filled with the tetrafluoroethylene lining; the containing cavity is in a cuboid shape, and the outer wall of the tetrafluoroethylene lining is matched with the cuboid shape of the containing cavity and tightly attached to the inner wall of the containing cavity. In the tank bottom ball valve, the ball is totally and tightly wrapped by the tetrafluoroethylene lining serving as a valve base, matching between the tetrafluoroethylene lining and the ball is tighter, and the sealing effect is good. Furthermore, all the space in the containing cavity, except for the ball, the feed port and the discharge port is filled with the tetrafluoroethylene lining, on one hand, the wrapping intensity of the tetrafluoroethylene lining to the ball is improved; on the other hand, dirt is prevented for accumulating, and the inner portion of the ball valve is made to be more sanitary. At last, after the tetrafluoroethylene lining is tightly attached to the inner wall of the cuboid-shaped containing cavity, sealing of the tetrafluoroethylene lining and the ball is facilitated, stress concentration is not prone to occurring, and meanwhile rotation of the ball can be made to be smoother.
Description
Technical field
The utility model relates to a kind of tank bottom ball valve with tetrafluoro liner.
Background technique
In the spheroid placing chamber of tradition tank bottom ball valve, spheroid is installed, but only at material feeding mouth and discharge port place, valve seat is set, the position beyond valve seat is in vacant state.The tetrafluoro liner of this tank bottom ball valve is imperfect to the parcel of spheroid, and leaves a large amount of rest position, easily accumulates dirt.And, because the pressure medium of tank bottom ball valve is larger, easily make valve seat distortion, and then cause poorly sealed close.
Model utility content
In view of the deficiency that background technique exists, the sealing that technical problem to be solved in the utility model has been to provide a kind of valve seat and spheroid more tightly and be difficult for accumulating the tank bottom ball valve with tetrafluoro liner of dirt.
The utility model takes following technological scheme to complete: tank bottom ball valve; comprise valve body; described valve body is interior with spheroid placing chamber; spheroid placing chamber is interior with tetrafluoro liner; described tetrafluoro liner is with material feeding mouth and discharge port; it is characterized in that: described tetrafluoro liner is wrapped spheroid, the institute that described tetrafluoro liner takes in spheroid placing chamber except spheroid and material feeding mouth, discharge port has living space; Described spheroid placing chamber is rectangular shape, and the outer wall of described tetrafluoro liner mates and be close to spheroid placing chamber inwall with the rectangular shape of spheroid placing chamber.
In the utility model, as the tetrafluoro liner of valve seat, wrap spheroid comprehensively, make both cooperations tightr, sealing effect is better.And, the institute that tetrafluoro liner takes in placing chamber except spheroid and material feeding mouth, discharge port has living space, and makes not have any position that may accumulate dirt in placing chamber, improves on the one hand the parcel dynamics of tetrafluoro liner to spheroid, prevent again that on the other hand dirt from accumulating, make ball valve inside health more.Finally, after the placing chamber inwall of tetrafluoro liner and rectangular shape is adjacent to, make placing chamber more even to the pressure of tetrafluoro liner, be conducive to the sealing of tetrafluoro liner and spheroid, be difficult for producing stress and concentrate, equally also can make the rotation of spheroid more smooth and easy.
Accompanying drawing explanation
The utility model has following accompanying drawing:
The structure cross-sectional schematic of the tank bottom ball valve that Fig. 1 provides for the utility model the first embodiment.
The structure cross-sectional schematic of the tank bottom ball valve that Fig. 2 provides for the utility model the second embodiment.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, further describes by reference to the accompanying drawings each details and the working principle thereof of embodiment below again.
As shown in Figure 1, the tank bottom ball valve that the utility model provides, comprise valve body 1, described valve body 1 is interior with spheroid placing chamber 2, spheroid placing chamber 2 is interior with tetrafluoro liner 3, described tetrafluoro liner 3 is with material feeding mouth 4 and discharge port 5, and described tetrafluoro liner 3 is wrapped spheroid 6, and the institute that described tetrafluoro liner 3 takes in spheroid placing chamber 2 except spheroid 6 and material feeding mouth 4, discharge port 5 has living space; Described spheroid placing chamber 2 is rectangular shape, and the outer wall of described tetrafluoro liner 3 mates and be close to spheroid placing chamber 2 inwalls with the rectangular shape of spheroid placing chamber 2.In the present embodiment, described tetrafluoro liner 3 has symmetrical two, and this two-piece type structure is convenient to the installation of replacing and spheroid 6.
As shown in Figure 2, the utility model the second embodiment and the first embodiment are basic identical, difference is only: described valve body 1 outside is with the drainage conduit 7 communicating with spheroid 6, drainage conduit 7 outer ends have the first clamp band type connection end, described tank bottom ball valve disposes negative pressure device 9, negative pressure device is connected with conduit 10, conduit 10 is with the second clamp band type connection end mating with the first clamp band type connection end, and described the first clamp band type connection end and the second clamp band type connection end are by clip 8 snappings.After tank bottom ball valve configuration clamp band type connection end, facilitate it to be connected with negative pressure device 9, and suction is provided during the material drainage difficulty that negative pressure device 9 can be in tank bottom ball valve, discharge promoting.
