Abstract
The utility model discloses a tank bottom ball valve with a teflon lining. The tank bottom ball valve with the teflon lining comprises a valve body, a ball placing cavity is formed in the valve body, the teflon lining is arranged in the ball placing cavity, a feed port and a discharge port are arranged in the teflon lining, the teflon lining wraps a ball tightly, the teflon lining occupies all the space of the placing cavity except the ball, the feed port and the discharge port, the inner surface of the teflon lining is formed by a first curved face and a second curved face which have different inner diameters in a smooth transition mode, the inner diameter of the first curved face is larger than the inner diameter of the second curved face, the inner wall, close to the feed port or the discharge port, of the teflon lining accords with the second curved face, and the inner wall, far away from the feed port or the discharge port, of the teflon lining accords with the first curved face. According to the tank bottom ball valve with the teflon lining, sealing of a valve seat and the ball is tighter, and dirt can not be accumulated easily.
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.
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: the tank bottom ball valve with tetrafluoro liner, 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, described tetrafluoro liner is wrapped spheroid, described tetrafluoro liner takes in placing chamber except spheroid and material feeding mouth, institute outside discharge port has living space, described tetrafluoro liner internal surface is seamlessly transitted and is formed by the different first surface of internal diameter and the second curved surface, the internal diameter of described first surface is greater than the internal diameter of the second curved surface, the inwall being lining with in described tetrafluoro near material feeding mouth or discharge port place meets the second curved surface, the inwall being lining with in described tetrafluoro away from material feeding mouth or discharge port place meets first surface.
In the utility model, as the tetrafluoro liner of valve seat, wrap spheroid comprehensively, make both cooperations tightr, sealing effect is better.And, tetrafluoro liner internal surface is seamlessly transitted and is formed by the different first surface of internal diameter and the second curved surface, the internal diameter of described first surface is greater than the internal diameter of the second curved surface, wherein the less parcel dynamics to spheroid of the diameter of the second curved surface is larger, makes setting position wrap up the better tightness to the position, edge of tetrafluoro liner after spheroid near the second curved surface of material feeding mouth or discharge port.Finally, 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.
Accompanying drawing explanation
The utility model has following accompanying drawing:
The structure cross-sectional schematic of the tank bottom ball valve with tetrafluoro liner that Fig. 1 provides for the utility model.
Fig. 2 is the structure cross-sectional schematic of the left side lobe of the tetrafluoro liner in Fig. 1.
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 Fig. 1, shown in Fig. 2, the tank bottom ball valve with tetrafluoro liner 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, described tetrafluoro liner 3 is wrapped spheroid 6, described tetrafluoro liner 3 takes in placing chamber 2 except spheroid 6 and material feeding mouth 4, institute outside discharge port 5 has living space, described tetrafluoro liner 3 internal surfaces are seamlessly transitted and are formed by the different first surface of internal diameter and the second curved surface, the internal diameter of described first surface is greater than the internal diameter of the second curved surface, inwall near material feeding mouth 4 or discharge port 5 places on described tetrafluoro liner 3 meets the second curved surface, inwall away from material feeding mouth 4 or discharge port 5 places on described tetrafluoro liner 3 meets first surface.Described tetrafluoro liner 3 has symmetrical two in the present embodiment, when 3 wearing and tearing of tetrafluoro liner need to be changed, only needs dismounting valve body 1 to tear open from both sides peace.
Claims (2)
1. a tank bottom ball valve with tetrafluoro liner, 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, described tetrafluoro liner takes in placing chamber except spheroid and material feeding mouth, institute outside discharge port has living space, described tetrafluoro liner internal surface is seamlessly transitted and is formed by the different first surface of internal diameter and the second curved surface, the internal diameter of described first surface is greater than the internal diameter of the second curved surface, the inwall being lining with in described tetrafluoro near material feeding mouth or discharge port place meets the second curved surface, the inwall being lining with in described tetrafluoro away from material feeding mouth or discharge port place meets first surface.
2. the tank bottom ball valve with tetrafluoro liner according to claim 1, is characterized in that: described tetrafluoro liner has symmetrical two.
