Abstract
The utility model discloses a butterfly valve comprising a valve body and a valve seat, wherein the valve body and the valve seat are detachably connected together through screws; the valve body comprises a hand wheel for manually driving the butterfly valve, a gearbox connected with the hand wheel, and a valve rod connected with the gearbox; a valve block is fixedly connected to the valve rod; the valve seat comprises a connecting base connected with the valve body, a valve block cavity for containing the valve block and mounting holes for mounting the valve seat; the mounting holes are evenly formed at the outer periphery of the valve block cavity. The butterfly valve provided by the utility model has the advantages that the valve body and the valve seat are detachably mounted so that the whole butterfly valve can be mounted conveniently, and simultaneously, a plurality of mounting holes are evenly formed at the outer periphery of the valve block cavity, so that harmful drift of the valve seat can be effectively prevented.
Description
Technical field
The utility model relates to a kind of valve, more precisely, is a kind of butterfly valve.
Background technique
Butterfly valve is Flap valve again, is a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously.The closure member of butterfly valve (flap or butterfly plate) is a disk, rotates a kind of valve that reaches open and close around valve shaft, and main rising cut off and throttling usefulness on pipeline.Existing reed valve adopts the one casting to form, and very heaviness is installed, and harmful displacement also takes place easily.
Chinese invention patent ZL 02103379.X discloses a kind of butterfly valve; It comprises that one is installed in and makes the seat ring that seals between clack box inner peripheral surface and valve body when closing on its clack box inner peripheral surface; Be characterized in; Form two valve shaft holes that valve rod connects each other face-to-face at said seat ring stream radial direction; Form between the hub portion around this valve shaft hole along the prominent bar of circumferentially inwardly giving prominence to, be crimped at closing direction when closing valve the valve body periphery continuously, the contacting part that this prominent bar contacts with the valve body periphery is formed in all curve-likes that the part of leaving hub portion is bloated to side to evolution, and roughly contacts simultaneously with the periphery of valve body.This butterfly valve also is to adopt to be made into integration, and very trouble is installed.
The model utility content
The utility model mainly is to solve the existing in prior technology technical problem, can effectively avoid harmful displacement and butterfly valve easy for installation thereby provide a kind of.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of butterfly valve; Comprise valve body and valve seat; Described valve body removably is connected through screw with valve seat; Described valve body comprises handwheel, gear-box that is connected with described handwheel and the valve rod that is connected with described gear-box that is used for the described butterfly valve of manual drives; One valve block is fixedly connected with described valve rod, and described valve seat comprises the connecting base that is connected with described valve body, the mounting hole that is used to hold the valve block cavity of described valve block and is used to install described valve seat.
As the preferred embodiment of the utility model, described mounting hole is arranged on the excircle of described valve block cavity equably.
As the preferred embodiment of the utility model, be provided with strengthening rib between the described mounting hole.
Therefore, detachable valve body and the valve seat of installing of the butterfly valve utilization of the utility model made things convenient for the installation of whole butterfly valve, simultaneously, utilizes and evenly is arranged on a plurality of mounting holes on the valve block cavity excircle, can effectively prevent harmful displacement of valve seat.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 3 is the perspective view of the valve seat of the butterfly valve among Fig. 2;
Fig. 4 is the details enlarged diagram of a-quadrant of the valve seat of the butterfly valve among Fig. 3.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
The utility model provides a kind of can effectively avoid harmful displacement and butterfly valve easy for installation.
Extremely shown in Figure 4 like Fig. 1; A kind of butterfly valve 1; Comprise valve body 2 and valve seat 3, this valve body 2 and valve seat 3 removably are connected through screw, and this valve body 2 comprises handwheel 21, gear-box 22 that is connected with this handwheel 21 and the valve rod 24 that is connected with this gear-box 22 that is used for this butterfly valve of manual drives; One valve block 23 is fixedly connected with this valve rod 24, and this valve seat 3 comprises the connecting base 33 that is connected with this valve body 2, the mounting hole 32 that is used to hold the valve block cavity 31 of this valve block 23 and is used to install this valve seat 3.
This mounting hole 32 is arranged on the excircle of this valve block cavity 31 equably.
Be provided with strengthening rib 321 between this mounting hole 32.
Detachable valve body and the valve seat of installing of the butterfly valve utilization of this model utility made things convenient for the installation of whole butterfly valve, simultaneously, utilizes and evenly is arranged on a plurality of mounting holes on the valve block cavity excircle, can effectively prevent harmful displacement of valve seat.
The mentality of designing of the utility model below only is described with a mode of execution, and under the situation that system allows, the utility model can expand to external more function module simultaneously, thereby expands its function to greatest extent.
The above is merely the embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
