Abstract
The utility model provides a low friction direction flashboard and valve thereof. When it had been solved current gate valve and is moving crosswise the installation, the flashboard just formed the dry friction with the direction muscle, and the moment of torsion just aggravates, and the flashboard can block dead problem in the time of serious. It includes the flashboard, and valve body inner wall and flashboard both sides correspond the position and are equipped with the direction muscle, be equipped with the rolling device between the direction muscle of flashboard and at least one side. The utility model discloses a gate valve simple structure, coefficient of friction is low, convenient to use.
Description
Technical field
This utility model relates to a kind of flashboard, particularly relates to a kind of low friction and guides flashboard and valve thereof.
Background technology
Valve is the control parts in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of fluid control systems, various valves used from simplest stop valve to extremely complex robot control system(RCS), its kind and specification are the most various.Valve can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Flashboard in gate valve generally moves up and down by the guiding rib on valve body, and sometimes valve is to install sidewards, and this time, flashboard was formed for dry friction with guiding rib, and moment of torsion just increases the weight of, and the when of serious, flashboard can be stuck.It is thus desirable to one can be in any installment state all good guidance, flashboard that will not be stuck.
Utility model content
In order to solve the problem in background technology, this utility model offer one can be at any installment state all good guidance, flashboard that will not be stuck and gate valve thereof.
To achieve these goals, this utility model provides a kind of low friction to guide flashboard, and including flashboard, valve interior wall and flashboard both sides correspondence position are not provided with guiding rib, are provided with tourelle between the guiding rib of described flashboard and at least side.
As a kind of improvement of the present utility model, the surface that described flashboard faces guiding rib is provided with the groove placing tourelle, and described tourelle in the grooves and exists space with groove floor.
Entering a kind of to improve as of the present utility model, described tourelle is roller, and described roller includes:
Rotating shaft: be fixed on flashboard；And
Wheel body: be movably set in rotating shaft；
Wherein, there is space in the surface of wheel body and groove floor.
Enter a kind of to improve as of the present utility model, between described flashboard and both sides guiding rib, be equipped with roller.
A kind of valve guiding flashboard equipped with above-mentioned low friction, including valve body, valve gap, valve rod, described valve body is connected with valve gap, is provided with above-mentioned low friction and guides flashboard in valve body.
Entering a kind of to improve as of the present utility model, described flashboard is provided with the mounting groove for being connected with valve rod, and described valve rod is connected with flashboard by mounting groove.
Entering a kind of to improve as of the present utility model, described mounting groove is " convex " shape, and described valve rod is provided with the installation portion suitable with described mounting groove.
The beneficial effects of the utility model are: low friction of the present utility model guides flashboard, valve inwall and flashboard both sides are that correspondence position is provided with guiding rib, it is provided with tourelle between the guiding rib of described flashboard and at least side, therefore rolling friction is formed between flashboard and guiding rib, substantially reduce frictional force, even if making valve be transversely mounted, frictional force between flashboard and guiding rib also can be smaller, the moment needed is smaller, do not have stuck situation, it is possible to easily open and close flashboard.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the valve of this utility model embodiment.
Fig. 2 is the structural representation of the low friction guiding flashboard of this utility model embodiment.
Fig. 3 is the structural representation of the tourelle in Fig. 2 at A-A.
Wherein: 1, flashboard；11, groove；12, space；13, mounting groove；2, valve body；3, guiding rib；4, tourelle；41, roller；42, rotating shaft；43, wheel body；5, valve gap；6, valve rod；61, installation portion.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
As shown in Figure 1, to achieve these goals, this utility model provides a kind of low friction to guide flashboard, including flashboard 1, valve 2 inwall and flashboard 1 both sides correspondence position are provided with guiding rib 3, it is provided with tourelle 4 between the guiding rib 3 of described flashboard 1 and at least side, therefore rolling friction is formed between flashboard and guiding rib, substantially reduce frictional force, even if making valve be transversely mounted, the frictional force between flashboard and guiding rib also can be smaller, and the moment of needs is smaller, do not have stuck situation, it is possible to easily open and close flashboard.
The surface that described flashboard 1 faces guiding rib 3 is provided with the groove 11 placing tourelle 4, and described tourelle 4 is positioned in groove 11 and there is space 12 with groove 11 bottom surface, and tourelle can be the most movable in a groove；Groove also can play the guiding role, prevent flashboard from offseting in motor process as the gathering sill adaptive with guiding rib, it is ensured that the sealing of flashboard and safety simultaneously.
Described tourelle 4 is roller 41, and described roller 41 includes:
Rotating shaft 42: be fixed on flashboard 1；And
Wheel body 43: be movably set in rotating shaft 42；
Wherein, there is space 12 in the surface of wheel body 43 and groove 11 bottom surface.Use said structure, take roller as tourelle so that gate panel surface and guiding rib surface are rolling friction, frictional force is greatly reduced, especially when there being dirt to be mingled with between flashboard and guiding rib, flashboard is pulled more favourable by less frictional force, is also easier to guide simultaneously.
Being equipped with roller 41 between described flashboard 1 and both sides guiding rib 3 so that valve need not be installation direction when mounted, each mounting means all can realize low friction.
Guide the valve of flashboard equipped with above-mentioned low friction, valve is gate valve, and including valve body 2, valve gap 5, valve rod 6, described valve body 2 is connected with valve gap 5, is provided with above-mentioned low friction and guides flashboard in valve body 2.Forming rolling friction between flashboard and guiding rib, substantially reducing frictional force, even if making valve be transversely mounted, frictional force between flashboard and guiding rib also can be smaller, the moment needed is smaller, does not haves stuck situation, it is possible to easily open and close flashboard.
Described flashboard 1 is provided with the mounting groove 13 for being connected with valve rod 6, and described valve rod 6 is connected with flashboard 1 by mounting groove 13, and simple in construction is easy for installation.
In order to make flashboard firmly install with valve rod, described mounting groove 13 is " convex " shape, and described valve rod 6 is provided with the installation portion 61 suitable with described mounting groove 13.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention; but invention thought of the present utility model is not limited to that utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
