Abstract
The utility model discloses a rising stem type gate valve. The rising stem type gate valve comprises a valve body, a valve cover, a bracket, a valve rod, a gate and a valve rod nut; the valve cover is fixed on the valve body; the bracket is fixed on the valve rod; the lower end of the valve rod nut is hinged with the bracket; a handwheel is fixed at the upper end of the valve rod nut through a locking nut; the inner side of the valve rod nut is in threaded connection with the valve rod; the gate is clamped at the lower end of the valve rod; a sealing ring is arranged between the valve cover and the valve rod; grooves are formed on the inner circumferential surface and the outer circumferential surface of the sealing ring; and O-shaped sealing circles are arranged in the grooves. A required strength for opening or closing the gate valve is reduced.
Description
Technical field
The utility model relates to a kind of pipeline gate valve, especially relates to the used Outside screw stem rising through handwheel type gate valve of a kind of water supply line.
Background technique
At present, the water supply line Outside screw stem rising through handwheel type gate valve comprises parts such as valve body, valve gap, flashboard, valve rod, Stem Mut, dust ring, locking nut, seal ring, handwheel.More the valve gap of water supply line rising stem (RS.) gate sealing valve and the sealing between the valve rod are adopted gland to compress graphite packing and are sealed, but can give axial force of valve rod after graphite packing is compacted, make valve rod rotarily open power and the power of closing increases, cause rotation hand wheel control opening and closing to need very big power, inconvenient opening and closing.
The model utility content
The purpose of this utility model provides a kind of Outside screw stem rising through handwheel type gate valve, when solving the gate valve opening and closing, and the problem that the power that rotary valve rod need apply is very big.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Outside screw stem rising through handwheel type gate valve, comprise valve body, valve gap, support, valve rod and flashboard and Stem Mut, described valve gap is fixedly installed on the valve body, described support is fixedly installed on the valve gap, described Stem Mut lower end is hinged on the support, described Stem Mut upper end is set with handwheel by locking nut, and described Stem Mut is inboard to be connected with threaded stem, and described valve rod lower end is connected with flashboard; Be provided with seal ring between described valve gap and the valve rod, offer groove on the described seal ring inside and outside circle side face, be provided with O type circle in the described groove.
In the utility model, be provided with pad between described seal ring lower end surface and the valve gap.
Described seal ring material is a brass.
The beneficial effects of the utility model: owing between valve gap and valve rod, be provided with seal ring, offer groove on the inside and outside circle side face of seal ring, be provided with O type circle in the described groove, making gate valve open or close the power that needs reduces, the performance of product further strengthens, and further improve 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 Outside screw stem rising through handwheel type gate valve.
Among the figure: 1. valve body, 2. flashboard, 3. vulcanized rubber layer, 4. valve rod, 5. headrest sheet in first, 6. nut, 7. valve gap, 8. pad, 9. headrest sheet, 12. supports, 13. dust rings, 14. Stem Muts, 15. handwheel pads, 16. handwheels, 17. locking nuts in seal ring, the 10.O type circle, 11. second.
Embodiment
Embodiment 1, and as shown in Figure 1, a kind of Outside screw stem rising through handwheel type gate valve comprises valve body 1, valve gap 7, support 12, valve rod 4 and flashboard 2 and Stem Mut 14, and described valve gap 7 is fixedly installed on the valve body 1 by nut 6, is provided with headrest sheet 5 in first between valve body 1 and the valve gap 7; Described support 12 is fixedly installed on the valve gap 7 by nut, is provided with headrest sheet 11 in second between valve gap 7 and the support 12, is provided with dust ring 13 between support 12 and the valve rod 4; Described Stem Mut 14 lower ends are hinged on the support 12, described Stem Mut 14 inboard and valve rod 4 scyewed joint, and described Stem Mut 14 upper ends are set with handwheel 16 by locking nut 17, are provided with handwheel pad 15 between handwheel 16 and the support 12; Described valve rod 4 is provided with projection bottom, and projection is connected in the groove of offering flashboard 2 upper ends, and the sulfuration of the appearance of flashboard has vulcanized rubber layer 3; Be provided with seal ring 9 between described valve gap and the valve rod, described seal ring material is a brass, offers groove on the described seal ring inside and outside circle side face, is provided with O type circle 10 in the described groove.Be provided with pad 8 between described seal ring lower end surface and the valve gap.
Handwheel under forward and reverse external force effect, the rotary valve rod nut, Stem Mut interlock valve rod, valve rod do to be gone up or motion down along Stem Mut, this motoricity drives flashboard and rises or fall, so that unlatching or throttle down.This gate valve needs very little power just can realize the unlatching of flashboard or closes, and the performance of product further strengthens, and further improve working life.
