Abstract
The utility model relates to a quick-connect type variable diameter butterfly valve, which comprises a valve body, a valve plate, a valve rod and a handle, wherein the valve plate is placed in the center of the valve body, the valve rod is connected with the valve plate, and the handle is fixed onto the top end of the valve rod. The quick-connect type variable diameter butterfly valve is characterized in that two ends of the valve body are provided with inner screw threads, the screw threads at one end of the valve body are in screw connection with a stepped internal square joint, two ends of a stepped shaft stage of the internal square joint are equipped with external screw threads, one end of the stepped shaft stage of the internal square joint is connected with the valve body, the other end of the stepped shaft stage of the internal square joint is in screw connection with a quick-connect nut, and the center of the quick-connect nut penetrates through a hollow connecting sleeve with stepped stages. The quick-connect type variable diameter butterfly valve has the advantages of realizing quick-installation type connection valve by adopting the quick-connect nut, achieving convenient installation of the valve only by twisting the quick-connect nut tightly, extremely saving labor in the process of replacing the valve when in maintenance, meeting diameter-shrinking requirement for installing flow meters by employing variable diameter connectors, saving variable diameter pipes additionally installed among equal diameter valves, pipelines and flow meters and decreasing leakage places.
Description
Technical field
The utility model belongs to valve, relates in particular to a kind of quick-acting type reducing butterfly valve that is suitable for tap water, combustion gas and petroleum pipeline line.
Background technique
Along with the continual renovation of novel tube, the connection mode of valve and novel tube is also in continuous variation.The butterfly valve structure that above-mentioned industry is used is that the valve body two ends are provided with internal thread, is connected on the pipeline by outer silk.For example, in the pipeline construction of water supply industry before water pipe is registered one's residence the installation water meter, adopt at present PE, PPR, plastic tubes such as ABS, UPVC as aqueduct, butterfly valve is to be connected with the pipeline realization with aqueduct same material and the conversion part the center is inlaid with outside thread by one usually.During construction, at first use portable heat-conglutinating machine at the scene conversion part and plastic pipe to be cast into one, and then the internal thread of valve and the outer silk on the conversion part are spirally connected, this kind mounting type is: must realize fastening by rotating big valve.Very heavy and dangerous, and need bigger installing space.For valve operation convenience in future, when mounted valve, the position of valve handle must be up simultaneously.Therefore, through regular meeting following situation appearring during installation: owing to pull it green link is damaged; Or not tight because valve is twisted, can't be by bulge test.Above-mentioned mounting type not only installation quality is poor, and is not easy to maintenance.Must cut off the water completely if change valve, cut off pipeline and change.The industry demands breaking this traditional mounting type urgently, develops a kind of new ready-package valve.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of convenient quick-acting type reducing butterfly valve that connection and favourable maintenance are installed is provided.
The utility model for achieving the above object, by the following technical solutions: a kind of quick-acting type reducing butterfly valve, comprise valve body and the valve plate that places the valve body center, the valve rod that is connected with valve plate, be fixed on the handle of valve stem tip, it is characterized in that: described valve body two ends are provided with internal thread, valve body one end internal thread is bolted with square joint in the cascade, square joint ladder pillow block two ends are provided with outside thread in described, the one end is connected with valve body, the other end is bolted with fast connected nut, and the hollow connecting sleeve of band ladder platform is run through at fast connected nut center.
The square joint exterior edge face is provided with seal groove, built-in O-ring seals in described.
The internal diameter of described hollow connecting sleeve and external plastic tube external diameter are slidingly matched.
The described valve body the other end is bolted with the reducing interface.
Beneficial effect: adopt fast connected nut, realized that ready-package connects valve.Only need screw fast connected nut just can conveniently install valve, and it is also very laborsaving to change valve during maintenance.Adopt the reducing interface can satisfy the undergauge requirement that flowmeter is installed, having saved needs the reducer pipe fitting that installs additional, the minimizing leakage point between isometrical valve and pipeline, the flowmeter.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
See accompanying drawing for details, a kind of quick-acting type reducing butterfly valve, comprise valve body 2 and the valve plate 7 that places the valve body center, the valve rod 8 that is connected with valve plate, the handle 9 that is fixed on valve stem tip, described valve body two ends are provided with internal thread, valve body one end internal thread is bolted with square joint 3 in the cascade, and described interior square joint ladder pillow block two ends are provided with outside thread, and its threaded one end is connected with valve body, the other end is bolted with fast connected nut 5, and the hollow connecting sleeve 6 of band ladder platform is run through at fast connected nut center.The square joint exterior edge face is provided with seal groove 10, built-in O-ring seals 4 in described.The internal diameter of described hollow connecting sleeve and external plastic tube 11 external diameters are slidingly matched.The described valve body the other end is bolted with reducing interface 1.Valve body adopts HT200 cast iron, the sealing of inner chamber encapsulate, and valve plate adopts stainless casting alloy, and the outer surface epoxy paint is anticorrosion.Interior square joint and reducing interface adopt HT200 cast iron, plating zinc on surface passivation.The hollow connecting sleeve is selected for use and the same material of external plastic tube.
To be applied in the bonding or hot melt of the external plastic tube of the hollow connecting sleeve at fast connected nut center and main line during construction and be cast into integral body, valve body will be connected work with promptly finishing after fast connected nut screws.Can guarantee the angle of valve handle at construction requirement.The reducing interface can satisfy the undergauge requirement that flowmeter is installed.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
