Description
Technical field
The utility model relates to a kind of valve, especially a kind of no-arbitrary pricing stop valve.
Background technique
Valve on market is of a great variety, and current most of valve improves conventional construction, to reduce wearing and tearing between parts to improve sealing effect.But its internal structure is complicated, and sealing effect is undesirable, difficulty of processing is large, and cost is high, and the life-span is short, and particularly after inner body wearing and tearing, will remove and change part and even scrap by whole valve, this brings a lot of trouble to user, also causes waste.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, good airproof performance, no-arbitrary pricing stop valve easy to maintenance.
The utility model is solved by following technical proposal: comprise the valve body, valve rod, valve gap, handwheel, seal ring, the packing ring that are provided with intake-outlet, the valve rod bottom be wherein in valve cavity is provided with seal bar, by packing ring, seal ring and be enclosed within valve rod bonnet and coordinate, valve gap is screwed by the screw-internal thread fit on outside thread and valve body, on valve gap, cover has blind nut and round nut, screwed by the outside thread on valve gap and round nut screw-internal thread fit, valve stem tip is provided with handwheel and is screwed, and handwheel is by the screw-internal thread fit of outside thread and blind nut.
Further, the adapter screw thread of valve body adopts cone type.
The beneficial effects of the utility model have broken traditional valve top to need gland sealed defect: adapter screw thread adopts cone type, just can reach sealing effect when being connected with adapter without any need for auxiliary material; During operation, because its indoor design adopts internal thread to promote, during work, global shape is constant.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with embodiment's accompanying drawing, the utility model is described in further detail.
As shown in the figure, this embodiment comprises the valve body 10 being provided with intake-outlet, valve rod 5, valve gap 4, handwheel 1, seal ring 6 and 8, packing ring 7, valve rod 5 bottom be wherein in valve body 10 cavity is provided with seal bar 9, by packing ring 7, seal ring 6 and 8 be enclosed within valve rod 5 bonnet 4 and coordinate, valve gap 4 is screwed by the screw-internal thread fit on outside thread and valve body 10, on valve gap 4, cover has blind nut 3 and round nut 2, screwed by the outside thread on valve gap 4 and round nut 2 screw-internal thread fit, valve rod 5 top is provided with handwheel 1 and is screwed, handwheel 1 is by the screw-internal thread fit of outside thread and blind nut 3.The adapter screw thread of valve body 10 adopts cone type.
In use, close, wheel 1 is started in dextrorotation, because handwheel 1 is by the screw-internal thread fit of outside thread and blind nut 3, valve rod 5 is moved down, until closed; Open, counter-clockwise turn handwheel 1, make valve rod 5 moves, water is flow to from water intake, water outlet flows out.
