Abstract
The utility model relates to a butterfly valve, comprising a connecting clamping block assembly, which comprises a first connecting clamping block and a second connecting clamping block opposite to the first connecting clamping block. Each of the first connecting clamping block and the second connecting clamping block is provided with an angular part and an extending fixing part; the angular parts of the first connecting clamping block and the second connecting clamping block are opposite and form a diamond-shaped cavity capable of clamping a square valve rod; a cushion block is disposed between the extending fixing parts of the first connecting clamping block and the second connecting clamping block; and the extending fixing parts of the first connecting clamping block and the second connecting clamping block are connected fixedly. The connecting clamping block assembly provided by the utility model is capable of clamping the valve rod and a connecting shaft effectively.
Description
Technical field
The utility model relates to a kind of butterfly valve.
Background technique
Usually connect by being connected fixture block between the valve rod of butterfly valve and the coupling shaft, but existing connection fixture block is the one closed type, can't effectively clamp valve rod and coupling shaft that valve rod is prone to try to shirk responsibility.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of butterfly valve is provided, it connects the fixture block assembly can connect valve rod and coupling shaft effectively, and valve rod is difficult for slippage.
The utility model solves the technological scheme that its technical problem adopted: a kind of butterfly valve; Has the fixture block of connection assembly; Described connection fixture block assembly has the first connection fixture block, is connected the second relative connection fixture block of fixture block with first; The first connection fixture block is connected fixture block all to have angled portion and extends standing part with second; Is connected fixture block angled portion separately with second relatively and surround the rhombus cavity of clamping square valve rod but first connects fixture block, first connects fixture block extends between standing part is connected fixture block with second the extension standing part and accompanies cushion block, and the first connection fixture block extension standing part is connected the extension standing part fixed connection of fixture block with second.
The beneficial effect of the utility model is: when connection fixture block assembly clamping valve rod of the utility model and coupling shaft; Can connect fixture block is connected fixture block with second clamping elasticity through regulating first; Regulate first and connect fixture block is connected the rhombus cavity of fixture block angled portion formation separately with second size; Therefore, effectively clamping valve rod and coupling shaft.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation that connects the fixture block assembly in the utility model;
Wherein: 1. first connects fixture block, and 2. second connects fixture block, 3. cushion block.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1; A kind of butterfly valve; Has the fixture block of connection assembly; Connect the fixture block assembly and have and first connect fixture block 1, be connected relative second the connecting fixture block 2, the first and connect fixture blocks 1 and be connected fixture block 2 with second and all have angled portion and extension standing part of fixture block 1 with first, but the first connection fixture block 1 is connected fixture block 2 angled portion separately with second relative and surround the rhombus cavity of clamping square valve rod; First connects fixture block 1 extends and accompanies cushion block 3, the first between standing part is connected fixture block 2 with second the extension standing part and connect fixture blocks 1 and extend standing part is connected fixture block 2 with second extension standing part and pass through screw and spring washer fixed connection.
When connecting fixture block assembly clamping valve rod and coupling shaft; Can connect fixture block 1 is connected fixture block 2 with second clamping elasticity through regulating first; Regulate first and connect fixture block 1 is connected the rhombus cavity of fixture block 2 angled portion formation separately with second size, therefore, effectively clamping valve rod and coupling shaft.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
