Abstract
The utility model discloses an external thread stop valve, which includes a valve body (4) and a valve cap (6), wherein a valve seat forged with the valve body (4) into a whole is arranged in the valve body (4), a valve rod (11) integrated with a valve clack is further arranged in the valve body (4) and is connected with internal threads of the valve cap (6) through the external threads, a locking nut (10) is arranged on the outer side of the valve cover (6), and a hand wheel (12) is arranged at the outer end of the valve rod (11). A packing gasket (7), a packing (8) and a packing gland (9) are sequentially arranged from inside to outside between the valve cap (6) and a locking nut (10). The external thread stop valve has benefits as follows: the installation and the disassembly are convenient, the connection is firm, the seal performance is excellent and the external thread stop valve is safe and reliable.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of stop valve.
Background technique
Traditional stop valve has characteristics such as flow is little, pressure is big, thereby is widely used in industries such as power station, oil, chemical industry.But, because valve rod and flap adopt split-type structural, after under high pressure conditions for a long time, acting on repeatedly, phenomenons such as flap gets loose, distortion often occur, thereby cause poorly sealedly, production accident easily takes place.
The model utility content
At the shortcoming of existing stop valve, the utility model provides a kind of novel outside thread stop valve.
To achieve these goals, the measure taked of the utility model:
The outside thread stop valve comprises valve body and valve gap, is provided with in the valve body and its forging all-in-one-piece valve seat, also be provided with in the valve body and flap all-in-one-piece valve rod, valve rod is connected with the internal thread of valve gap by its outside thread, and the valve gap outside is provided with locking nut, and the valve rod outer end is provided with handwheel.
Between valve gap and locking nut, be provided with Packing seat, filler and Gland from inside to outside successively.
The beneficial effects of the utility model: install, convenient disassembly, connect fastening, good seal performance, safe and reliable.
Description of drawings
Fig. 1 structural representation of the present utility model.
Embodiment
The outside thread stop valve comprises valve body 4 and valve gap 6, is provided with in the valve body 4 and its forging all-in-one-piece valve seat, the valve seat wear-resisting property improves greatly, also be provided with in the valve body 4 and flap all-in-one-piece valve rod 11, improved the rigidity and the intensity of flap, realized the excellent sealing of flap and valve seat.Valve rod 11 is connected with the internal thread of valve gap 6 by its outside thread, and valve gap 6 outsides are provided with locking nut 10, and valve rod 11 outer ends are provided with handwheel 12, and is easy to operate, connection is fastening.Between valve gap 6 and locking nut 10, be provided with Packing seat 7, filler 8 and Gland 9, good airproof performance from inside to outside successively.The beneficial effects of the utility model: install, convenient disassembly, connect fastening, good seal performance, safe and reliable.
Those skilled in the art's simple modification and replacement all are within the protection domain of the present utility model in related domain.
