Abstract
The utility model relates to a key slot type valve plate three-eccentric high-performance sealing butterfly valve, which comprises a valve body; the valve body is internally provided with a valve plate component; a valve rod shaft sleeve is fixed on the valve plate component; a part of the valve rod penetrates into the valve rod shaft sleeve; the part of valve rod penetrating into the valve rod shaft sleeve is provided with a first groove; the valve rod shaft sleeve is provided with a second groove in the place corresponding to the first groove; and a cavity formed by the first groove and the second groove is internally provided with a flat key. The valve rod is connected with the valve rod shaft sleeve through a key slot; the valve rod is fixedly connected with the valve rod shaft sleeve; and the valve rod is stable to operate so that the service time of the valve is prolonged.
Description
Technical field
The utility model relates to the butterfly valve technical field, especially keyway formula valve plate three eccentric high-performance seal butterfly valves.
Background technique
Contact between its valve rod of eccentric-butterfly-valve of the prior art and the valve stem sleeve and be connected; Any effective non-skid feature is not arranged; Perhaps also there is the form that adopts taper pin to fix; But these modes still can not be effectively fixing valve rod, can not synchronous working effectively when valve rod is worked with valve stem sleeve, influence the valve using effect.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, provide keyway formula valve plate three eccentric high-performance seal butterfly valves, its valve rod is connected firmly with valve stem sleeve, and valve rod is stable, prolongs the service time of valve.
The utility model solves the technological scheme that its technical problem adopted: keyway formula valve plate three eccentric high-performance seal butterfly valves; Have valve body, valve board assembly is installed in the valve body, be fixed with valve stem sleeve on the described valve board assembly; The part valve rod is through in the valve stem sleeve; The part valve rod position that is through in the valve stem sleeve has first groove, has second groove with the corresponding place of first groove on the valve stem sleeve, is provided with flat key in the cavity that described first groove and second groove form.
The beneficial effect of the utility model is: be connected through keyway between the valve rod of the utility model and the valve stem sleeve, valve rod is connected firmly with valve stem sleeve, and valve rod is stable, prolongs the service time of valve.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the partial structurtes schematic representation of the utility model;
Wherein: 1. valve body, 2. valve board assembly, 3. valve rod, 4. flat key.
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.
Keyway formula valve plate three eccentric high-performance seal butterfly valves as shown in Figure 1; Have valve body 1, valve board assembly 2 is installed in the valve body 1, be fixed with valve stem sleeve on the valve board assembly 2; Part valve rod 3 is through in the valve stem sleeve; Part valve rod 3 positions that are through in the valve stem sleeve have first groove, have second groove with the corresponding place of first groove on the valve stem sleeve, are provided with flat key 4 in the cavity that first groove and second groove form.
Be connected through keyway between the valve rod 3 of the utility model and the valve stem sleeve, valve rod 3 is connected with valve stem sleeve firmly, and valve rod 3 is stable, prolongs the service time of valve.
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.
