Abstract
The utility model provides an upload ball valve, comprising a valve body, a valve cover, a valve rod, a limit board, a limit pin, a pre-fastening spring, a compression nut, a sealing sleeve, a pressing board, a valve base, a ball body, etc. The utility model is characterized in that the valve base is arranged with a handle, the pre-fastening spring is positioned between the upper flat surface of the pressing board and the step of the valve rod, and the pressing board is arranged on the upper flat surface of the valve base. The utility model has the advantages of convenient assembly and the disassembly of the valve, uniform sealing pressure proportion and reliable seal, and the ball body can actively adjust the sealing magnitude of interference.
Description
Affiliated technical field
The utility model relates to a kind of upper-mounting type ball valve that is used for industries such as nuclear power, petrochemical industry.
Background technique
Use the upper-mounting type ball valve in industries such as nuclear power, petrochemical industry at present, particularly small-bore ball valve, valve seat mounting or dismounting inconvenience, preloading spring is contained between valve rod and the spheroid, and the seal pressure inequality is regulated very inconvenience, and is sealed into conical surface linear sealing, and it is unreliable to seal.
Summary of the invention
For overcoming existing upper-mounting type ball valve valve seat mounting or dismounting inconvenience, sealing insecure deficiency, the utility model provides a kind of upper-mounting type ball valve, this upper-mounting type ball valve adopts band handle valve seat, preloading spring is contained between valve rod and the pressing plate, pressing plate is positioned on the valve seat on the plane, is sealed into the sphere face seal, and mounting or dismounting are convenient, seal pressure is even, and sealing is reliable.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of upper-mounting type ball valve, by valve body, valve gap, valve rod, limiting board, position limit pin, preloading spring, gland nut, stuffing box gland, pressing plate, valve seat, component such as spheroid are formed, spheroid is housed in the valve body, valve seat, valve seat is band handle valve seat, the face that valve seat contacts with spheroid is a sphere, two valve seat symmetries are installed in the valve body, stuffing box gland is housed in the valve gap, gland nut, preloading spring, limiting board, position limit pin, valve body, valve gap passes through double-screw bolt, nut connects, gland nut and valve gap inner chamber compress stuffing box gland by scyewed joint, preloading spring is on valve rod step and the pressing plate between the plane, pressing plate is contained on the last plane of valve seat, the adjusting of sealed increscence amount is by the passive spheroid active adjustment that is adjusted to of original spheroid like this, limiting board connects by square tenon with valve rod, and be arranged in the valve gap, be applicable to multiple connecting mode, be easy to debate the switching position of other valve at the scene during exchange apparatus.
The beneficial effects of the utility model are that the valve mounting or dismounting are convenient, but spheroid active adjustment sealed increscence amount, seal pressure is even, and sealing is reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's a sectional structural map
Fig. 2 is the plan view of valve seat
Fig. 3 is the right elevation of valve seat
Among the figure: 1. position limit pin; 2. limiting board; 3. junction of the edges of two sheets of paper screw; 4. gland nut; 5. stuffing box gland; 6. valve gap; 7. valve rod; 8. pad; 9. valve body; 10. pressing plate; 11. preloading spring; 12. valve seat; 13. spheroid.
Embodiment
As shown in Figure 1, spheroid (13) is housed in the valve body (9), two valve seats (12) symmetry is installed in the valve body (9), stuffing box gland (5) is housed in the valve gap (6), gland nut (4), limiting board (2), position limit pin (1), valve body (9), valve gap (6) passes through double-screw bolt, nut connects, middle back cushion sheet (8) sealing, gland nut (4) compresses stuffing box gland (5) with valve gap (6) inner chamber by scyewed joint, preloading spring (11) is positioned at valve rod (7) step and pressing plate (10) is gone up between the plane, pressing plate (10) is contained on the last plane of valve seat (12), limiting board (2) connects by square tenon with valve rod (7), and valve rod (7) connects by square tenon with spheroid (13).Fig. 1 position ball valve is in full-gear, and when dextrorotation rotating valve rod (7), valve rod (7) drives spheroid (13) and limiting board (2) together during half-twist, and when limiting board (2) contacts with position limit pin (1), ball valve is closed.
Claims (2)
