Abstract
Disclosed is a butterfly valve body device. The butterfly valve body device is composed of a split-type valve body, fixing bases, oval connecting holes, a butterfly plate connecting shaft, a sealing sleeve, a shaft handle base, a shaft base and a forged and pressed butterfly plate. The fixing bases are symmetrically arranged outside the split-type valve body. The fixing threaded holes are fixed in the middles of the fixing bases. The sealing sleeve is arranged in the split-type valve body. The forged and pressed butterfly plate is arranged in the sealing sleeve. The butterfly plate connecting shafts are arranged on two sides of the forged and pressed butterfly plate. The shaft handle base is arranged above the split-type valve body, and the shaft base is arranged below the split-type valve body. A coaxial reserved shaft hole is formed in the shaft handle base. A reserved hole of the sealing sleeve corresponds to the shaft hole. The butterfly plate connecting shaft is arranged in the shaft hole. The oval connecting holes are respectively and symmetrically arranged on two sides of the shaft handle base and two sides of the shaft base. The butterfly valve body device is a combined-type valve body and is convenient to install and easy to adjust. The soft back glue sleeve is tightly sealed and does not leak water. The butterfly plate and the valve rod are integrated in a forged and pressed mode, and therefore service life of the butterfly valve body device is prolonged.
Description
Technical field
The utility model relates to the valve body that pipeline uses, especially a kind of butterfly valve body device.
Background technique
At present, the valve body of original butterfly valve is an one, the one-step casting moulding, valve body easily splits, and machining accuracy is higher, has a little error just may cause the gum cover installation to go wrong (either large or small, poorly sealed the causing of big words leaked, and little words gum cover is not installed or the gum cover squeeze crack, becomes waste product); Installation procedure is comparatively complicated, and gum cover is installed earlier, and butterfly plate is installed then, valve shaft (if gum cover and valve body, or gum cover and valve body have a little error just may cause valve shaft not installed) is installed again, flat then butterfly plate, pressure testing; Then also will flat butterfly plate, boring, pin couples together butterfly plate and valve shaft that (if butterfly plate is not put down, butterfly plate and valve seat will poorly sealedly leak down; The hole trains off will cause the valve plate unbalance stress, and valve plate is smashed; Pin and butterfly plate); To change whole valve after the damage of components, very inconvenience.
Former valve body structure and centre distance only meet GB (GB) standard, in use can cause a lot of inconvenience, as: a set of model all will be carved by each country during foreign export, to adapt to this national standard.Client's flange size a little bias is not installed or is twisted to be installed in and becomes to leak.The client buy change export trade be standard not meet or the like the problems referred to above mainly be valve body bolt hole center apart from the matching problem of piping erection flange center distance, work out a kind of many standards valve body for overcoming the above problems. mainly be that the valve body bolt hole is made improvements, improve back one sleeving valve phantom type and can meet multiple standards.
In view of above-mentioned many reasons, need the butterfly valve apparatus of the valve of improvement pipeline.
The model utility content
The utility model is comparatively complicated for the installation procedure that solves original butterfly valve, and poorly sealed causing leaked, and gum cover is not installed or the gum cover squeeze crack, cause damage of product, by rational design, provide a kind of butterfly valve apparatus, valve body design split, easy for installation, the butterfly plate forging forming, valve rod and butterfly plate one reduce operation, minimizing is leaked, and has improved production.
The utility model is in order to realize above-mentioned goal of the invention, adopt following technological scheme: be by the split valve body, fixed base, oval attachment hole, dish plate connecting shaft, stuffing box gland, the footstalk seat, axle bed, forging and pressing dish plate constitutes, the external side of split-body valve is symmetrical arranged fixed base, the fixed base middle part is provided with fixing threaded hole, in the split valve body stuffing box gland is set, forging and pressing dish plate is set in the stuffing box gland, forging and pressing dish plate both sides are provided with dish plate connecting shaft, split valve body top is provided with the footstalk seat, the opposing party is provided with axle bed, the coaxial reservation axis hole of the corresponding axle bed of footstalk seat, the corresponding axis hole of the preformed hole of stuffing box gland is provided with dish plate connecting shaft in the hole.
Footstalk seat bilateral symmetry is provided with oval attachment hole, and the bilateral symmetry of axle bed is provided with oval attachment hole.
Beneficial effect: the combined type valve body, easy adjustment easy for installation, soft backrest gum cover sealing is closely water-tight, and butterfly plate and valve rod forging and pressing one have prolonged working life.
The utility model is through repeatedly experiment, work out more suitable valve body, when valve body is cast in two modules of valve body two ends filling, after the valve body casting is finished, cut from the valve body center, two ends are connected and fixed with clamping bolt, can guarantee the coaxality of valve body center hole like this, when gum cover or butterfly plate are installed,, can realize cooperating by regulating clamping bolt if gum cover is excessive.If gum cover has small amount of wear after a period of time, also can realize sealing by regulating clamping bolt, install simple, the most important is not worried matching problem, can also adjust when exerting pressure, and gum cover can be installed earlier, butterfly plate and valve rod can install earlier, then an assembling.Such valve body also has a benefit to be exactly no matter be which position of gum cover, butterfly plate, valve rod or valve body is damaged and can be keeped in repair then and there, changes Component, has improved stock utilization greatly, reduces cost and consumptive material.Improve back one sleeving valve phantom type and can meet following multiple standards:
