Abstract
The utility model discloses a non rising stem gate valve, which comprises a valve body, a valve cover, a valve stem, a gate plate and a compression nut, wherein the valve body is fixedly connected with the valve cover through bolt nuts, and the valve stem is positioned on the valve cover through a positioning ring and the compression nut; a hand wheel is fixed on the upper end of the vale stem through a bolt, and the lower end of the valve stem is in threaded connection with a valve stem nut; the valve stem nut is clamped in a groove arranged at the upper end of the gate plate, and the compression nut is fixed inside the upper end of the valve cover through threads; and a dust-proof gasket is arranged at the uppermost end of the valve cover. The compression nut of the gate valve is isolated from moisture and dust in air, so that the compression nut is not easy to rust, and thus the service life of a product is prolonged.
Description
Technical field
The utility model relates to a kind of pipeline gate valve, especially relates to the used inside screw non-rising stem type gate valve of a kind of water supply line.
Background technique
At present, the water supply line inside screw non-rising stem type gate valve includes parts such as valve body, valve gap, bonnet nut, flashboard, valve rod, Stem Mut, gland nut, positioning ring, handwheel.The gland nut of water supply line inside screw non-rising stem type gate valve has part to expose in the valve gap outside, easily divides with water in air to contact, and produces corrosion, need not be fixed by rust easily for a long time, causes inconvenience to use.And also reduce working life.
The model utility content
The purpose of this utility model provides a kind of inside screw non-rising stem type gate valve, and it is exposed externally to solve gland nut, the problem of easy-to-rust.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of inside screw non-rising stem type gate valve, comprise valve body, valve gap, valve rod and flashboard and gland nut, described valve body is fixedlyed connected by bolt and nut with valve gap, described valve rod is positioned on the valve gap by positioning ring and gland nut, there is handwheel described valve rod upper end by bolt, the lower end screw thread of described valve rod is connected with Stem Mut, and described Stem Mut is stuck in the groove of offering the flashboard upper end; It is inner that described gland nut screw thread is fixed on the valve gap upper end, and described valve gap is provided with dustproof gasket topmost.
In the utility model,, be provided with minipad between described gland nut and the valve gap in order to reach better sealing effect.Be provided with the 2nd O type circle between described gland nut and the valve rod.The suitable applying of valve body seat ring that is provided with on flashboard seat ring that is provided with on the described flashboard and the valve body.
The beneficial effects of the utility model: because the gland nut screw thread of inside screw non-rising stem type gate valve is fixed on inside, valve gap upper end, valve gap is provided with dustproof gasket topmost, gland nut and airborne moisture and dust are all kept apart, and gland nut is difficult for corrosion, has prolonged product working life.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 partly cuts open organigram for the utility model inside screw non-rising stem type gate valve.
Among the figure: 1. valve body, 2. the valve body seat ring, 3. flashboard, 4. the flashboard seat ring, 5. Stem Mut, 6. valve rod, 7. nut, 8. in headrest sheet, 9. valve gap, 10. an O type circle, 11. positioning rings, 12. gland nuts, 13. the 2nd O type circles, 14. minipads, 15. dustproof gaskets, 16. handwheels, 17. bolts.
Embodiment
Embodiment 1, as shown in Figure 1, and a kind of inside screw non-rising stem type gate valve, comprise valve body 1, valve gap 9, valve rod 6 and flashboard 3 and gland nut 12, flashboard 3 is arranged in valve body 1 body cavity, headrest sheet 8 sealings in valve body 1 and valve gap 9 usefulness, and valve body 1 is fixedlyed connected by bolt and nut 7 with valve gap 9; Described valve rod 6 is positioned on the valve gap 9 by positioning ring 11 and gland nut 12, gland nut and valve gap lock sealing, described valve rod upper end is fixed with handwheel 16 by bolt 17, the lower end screw thread of described valve rod is connected with Stem Mut 5, and described Stem Mut 5 is stuck in the groove of offering flashboard 3 upper ends; It is inner that described gland nut screw thread is fixed on the valve gap upper end, and described valve gap is provided with dustproof gasket 15 topmost.
In order to reach better sealing effect, be provided with minipad 14 between described gland nut and the valve gap.With an O type circle 10, be provided with the 2nd O type circle 13 between gland nut and the valve rod between valve gap and the valve rod, seal.The valve body seat ring 2 suitable applyings that are provided with on flashboard seat ring 4 that is provided with on the described flashboard and the valve body.
Valve rod is by the handwheel transferring power, and handwheel is in forward and reverse external force effect, rotary valve rod, and valve rod interlock Stem Mut, Stem Mut is done to go up or motion down along valve rod, and this motoricity drives flashboard and rises or fall, so that unlatching or throttle down.
The gland nut of this gate valve is hidden in valve gap, and the gland nut of gate valve is all kept apart with airborne moisture and dust, avoids corrosion, has prolonged product working life.And be convenient to install and replacing, use more reliable.
