Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of stop valve.
Background technique
The open-shut device of stop valve is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat, and the forms of motion of valve rod adopts lifting rotation rod-type, therefore usual flap is referred to as stop valve along the valve of valve seat center line movement.Valve rod due to such valve open or shutoff stroke relatively short, and there is cutting function very reliably, again due to the change of valve seat port and the stroke direct proportionality of flap, be very suitable for the adjustment to flow.Therefore, such stop valve valve that dams is suitable as and cuts off or regulate and throttling use very much.
At present, stop valve in use, sealability between flap and valve seat reduces, the situations such as easy appearance leakage, the working life of product is affected, and simultaneously because friction between valve rod and valve gap increases, handle may be caused cannot to occur the phenomenon of valve rod braking, thus make the unlatching of valve rod or close to lose efficacy, reduce the working life of valve.
Model utility content
The utility model embodiment technical problem to be solved is, provides a kind of stop valve, has higher sealing, and it is time saving and energy saving to operate, and extends the working life of valve.
In order to solve the problems of the technologies described above, the utility model embodiment provides a kind of stop valve, comprise valve body, valve rod, flap, valve gap, support and handle, be provided with upper channel and lower channel in described valve body, described valve body, above described lower channel, end face is provided with the first Sealing;
The second Sealing is provided with between described valve gap and described valve body;
The top of described support is formed with a groove;
Described handle is connected with the Stem Mut on described valve rod; Wherein, the intermediate portion of described Stem Mut is formed with the flange that is positioned at described groove, the below of described flange is provided with the first flat thrust-bearing, and the top of described flange is provided with the second flat thrust-bearing and bearing gland successively.
Wherein, described support is provided with a position-limit mechanism, and described valve rod is formed with the chute matched with described position-limit mechanism;
When described in described lever drive, valve rod moves up and down, described position-limit mechanism can move back and forth in described chute along described valve rod central axial direction.
Wherein, described first Sealing is made up of rubber or polytetrafluoroethylmaterial material.
Wherein, described second Sealing is made up of rubber or polytetrafluoroethylmaterial material.
Implement the utility model embodiment, there is following beneficial effect:
1, in the utility model embodiment, owing to arranging two flat thrust-bearings at Stem Mut place, thus the more effective driving power that improve valve rod, further reach time saving and energy saving effect;
2, in the utility model embodiment, owing to arranging position-limit mechanism, valve rod accurately can be located in movement process, avoid flap and valve gap to collide and occur loss, further extend the working life of valve.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, the accompanying drawing obtaining other according to these accompanying drawings still belongs to category of the present utility model.
The structural representation of the stop valve that Fig. 1 provides for the utility model embodiment;
Wherein: 1-valve body, 2-valve rod, 21-Stem Mut, 211-flange, 22-chute, 3-flap, 4-valve gap, 5-support, 51-groove, 6-handle, 7-first Sealing, 8-second Sealing, the flat thrust-bearing of 9-first, the flat thrust-bearing of 10-second, 11-bearing gland, 12-position-limit mechanism, 13-upper channel, 14-lower channel.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The direction that the utility model is mentioned and position term, such as " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " top ", " bottom ", " side " etc., be only the direction with reference to accompanying drawing or position.Therefore, the direction of use and position term are in order to illustrate and to understand the utility model, but not the restriction to the utility model protection domain.
As shown in Figure 1, the utility model embodiment provides a kind of stop valve, comprise valve body 1, valve rod 2, flap 3, valve gap 4, support 5 and handle 6, be provided with upper channel 13 and lower channel 14 in valve body 1, valve rod 2 penetrates in valve body 1 upper channel 13, flap 3 is fixed on the below of valve rod 2, Stem Mut 21 is fixed on the top of valve rod 2, wherein
Valve body 1 end face is provided with the first Sealing 7 be made up of rubber or polytetrafluoroethylmaterial material above lower channel 14, is formed and is tightly connected, will make not conducting between upper channel 13 and lower channel 14 when flap 3 leans with described first Sealing 7;
The second Sealing 8 be made up of rubber or polytetrafluoroethylmaterial material is provided with between valve gap 4 and valve body 1;
The top of support 5 is formed with a groove 51;
