Abstract
The utility model provides an angle type external-threaded needled valve, which comprises an operating hand wheel, a packing box, a packing box gland, a valve rod, a packing box base and a valve body, wherein the packing box is arranged in the hole in the upper of the packing box base, the upper end of the packing box base is provided with a thread to be connected with the packing box gland, the valve rod with the hand wheel passes through the packing box to stretch into the packing box base to be connected with the valve core positioned at the bottom of the valve body, the packing box base and the valve body are in threaded connection, and the valve body is internally provided with a passage. The angle type external-threaded needled valve disclosed by the utility model is characterized in that the outlet of the passage in the valve body is connected with two connection tubes which are mutually vertical. The utility model has the beneficial effects that the application on pipelines which are mutually vertical is more convenient, and the advantages of simple structure, convenience in maintenance, low processing cost, high production efficiency, and the like are provided.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of angie type outside thread needle type valve.
Background technique
At present, needle type valve has been widely used in industries such as water power, waterpower, chemical industry, oil refining, metallurgy.In existing technology; Needle type valve is made up of valve body, valve rod, spool usually; Through the operation handwheel at rotation valve rod top, drive the valve core rotation of valve rod lower end during work, and do to rise and descending motion; Thereby make spool that the passage of offering on the valve body is opened or stopped up, the unlatching that realizes needle type valve is with closed.Because when the adapter of most needle type valves, ran into orthogonal pipeline all point-blank, the needle type valve of this structure just can not use.
Summary of the invention
The problem that the utility model will solve provides a kind of angie type outside thread needle type valve of rational in infrastructure, withstand voltage, good airproof performance, especially is fit to be installed on the orthogonal pipeline.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of angie type outside thread needle type valve; Comprise that operation handwheel, stuffing box, stuffing box gland, valve rod, stuffing box seat, valve body, stuffing box are placed in the hole on stuffing box seat top; Stuffing box seat upper end is provided with screw thread and is connected with stuffing box gland, is with the valve rod of handwheel to pass that stuffing box stretches into the stuffing box seat and the spool that is positioned at bottom the valve body is connected, and stuffing box seat and valve body are threaded; Be provided with passage in the valve body, it is characterized in that: the outlet port of the passage in the valve body is connected with vertical two adapters each other.
Two adapters are internal thread with valve body and are connected.
The diameter of the thick and butt end in thin lower end, valve rod upper end is greater than the internal diameter of stuffing box.
Filler is an Expanded graphite in the stuffing box.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the more convenient application on orthogonal pipeline; Nut is installed on valve body; The cavity of valve rod through nut with operate handwheel and be connected, this structure qualification the rotation distance of valve rod, reduced the unnecessary at work rotation of valve rod; Reduced the wearing and tearing of valve rod and spool, prolonged needle type valve working life, improved the reliability of using.Have simple in structurely, easy to maintenance, processing cost is low, the manufacturing efficiency advantages of higher.

Embodiment
Like Fig. 1, shown in 2; The utility model provides a kind of angie type outside thread needle type valve; Comprise that operation handwheel 1, stuffing box 2, stuffing box gland 3, valve rod 4, stuffing box seat 5, valve body 6, stuffing box 2 are placed in the hole on stuffing box seat 5 tops; Stuffing box seat 5 upper ends are provided with screw thread and are connected with stuffing box gland 3, and the valve rod 4 of band handwheel 1 passes stuffing box 2 and stretches into stuffing box seat 5 and be connected with the spool 7 that is positioned at valve body 6 bottoms, and stuffing box seat 5 and valve body 6 are threaded; Be provided with passage 8 in the valve body 6, the outlet port of the passage 8 in the valve body 6 is connected with vertical each other two and takes over 9.
Two adapters 9 are internal thread with valve body 6 and are connected.
The diameter of the thick and butt end in thin lower end, valve rod 4 upper ends is greater than the internal diameter of stuffing box 2.
Filler is an Expanded graphite in the stuffing box 2.
The working procedure of this instance: when the needs Open valve; Through clockwise rotary manipulation handwheel 1, carry out spiral helicine moving upward together thereby drive valve rod 4, thereby make spool 7 move upward thereupon; Passage 8 conductings; When the butt end of valve rod 4 props up stuffing box 2 lower ends convexity just at this moment, the operation handwheel 1 that can stop the rotation, needle type valve is opened.When the needs throttle down, then rotate in the counterclockwise operation handwheel 1, move downward together thereby drive valve rod 4, spool 7 is descending thereupon until 8 mouthfuls in the passage that props up the lower end, the operation handwheel 1 that stops the rotation, passage 8 stops up, and needle type valve is closed.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
