Abstract
A hand-operated eyeglasses valve comprises a left valve body, a right valve body, a corrugated pipe, a valve plate, a sealing gasket, an adapting flange and two screw pairs which are separately located in the symmetrical two sides of circumference of the valve body. A line through centers crosses axial center of the valve body, and one of the screw pair is used as a turning cylinder of the valve plate. Due to the adoption of the above conformation, central distance of each screw pair is greatly shortened, and auricular branch of the valve body is shortened, and stiffener is not needed any more, and length of construction of the valve body is greatly shortened, which is shortened one third of material compared with a congener material of the valve, and processing charges can be reduced ten to fifteen percent. The utility model has the advantages of convenient employment and good hermeticity.
Description
The utility model relates to a kind of industrial valve, particularly a kind of improved manual glasses valve.
Valve is indispensable parts in the industry, and it is of a great variety, and purposes is different.Wherein manually glasses valve is to be widely used in the valve that gas-pipe lines such as metallurgy, chemical industry, municipal engineering cut off media, and it has simple in structure, reliable operation, is applicable to the advantage of various bore pipelines.In its structure, there are three screw pairs that valve plate is clamped or loosen, valve plate needs to rotate 180 degree around its rotating shaft (being one of them screw pair) in the open and close process, at this moment, two screw pairs can not hinder rotatablely moving of valve plate top by sun in addition, it is enough big that spacing between above-mentioned for this reason three screw pairs must design, with cause valve this journal stirrup lengthening and need be provided with stiffening rib, cause finally that this structure of valve is huge, weight increases.
The purpose of this utility model provides a kind of sealing effect manual glasses valve good and simple in structure.
The purpose of this utility model is realized by following technological scheme:
A kind of manual glasses valve, it comprises left valve barrel, right valve barrel, bellows, valve plate, sealing gasket, adpting flange, its special improvements are, it is provided with two screw pairs, lay respectively at the valve body circumference to the both sides, border, its line of centres is made its rotatingshaft by the valve body axle center behind one of them screw pair suit valve plate.
Above-mentioned manual glasses valve also is provided with two auxiliary clamping bolts on the circumference of described valve body, they also lay respectively at the valve body circumference to the both sides, border, its line of centres is by the valve body oil heart and vertical with other line of centres of two screw pairs.
After adopting said structure, the centre distance of screw pair shortens dramatically, and the valve body journal stirrup shortens and do not need to use stiffening rib again, and the structure length of valve body also shortens greatly, therefore reduces three minutes one with bore valve consumption material, and processing charges reduces 10-15%; Simultaneously, change two screw pairs and two auxiliary clamping bolts into after, operate still easily, and make clamping point become four by three, the sealability of valve is more guaranteed.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the side view of Fig. 1.
As we can see from the figure, the utility model relates to a kind of manual glasses valve, it comprises left valve barrel 1, right valve barrel 2, bellows 3, valve plate 4, screw pair 6, auxiliary clamping bolt 7, adpting flange 8 etc.Valve plate 4 is straight-plate-types, above arranged side by side through hole and blind hole.Screw pair 6 is two, lays respectively at the symmetrical both sides of valve body circumference, and its line of centres is by the valve body axle center, and one of them screw pair is as the rotatingshaft of valve plate, and valve plate can rotate around this axle.Also be provided with two auxiliary clamping bolts 7 on the valve body circumference, they and two spirals revolve secondary 6 and are distributed on the valve body circumference.At work, when need be, unclamp screw pair 6, and unclamp and take off auxiliary clamping bolt 7, valve plate 4 is rotated 180 degree, screw screw pair 6 and fixing auxiliary clamping bolt 7 behind the location the through hole of valve plate 4 and blind hole transposition.Manually the left valve barrel 1 of glasses valve, right valve barrel 2 can be connected and fixed by adpting flange 8 and pipeline, uniform attachment hole 9 on the circumference of adpting flange, and the effect of bellows 3 is to make valve body that the leeway of displacement is arranged when opening/shutting valve.
The screw pair of general manual glasses valve is three, be symmetrically distributed on the valve body circumference, when the needs rotational valve plate, the top of valve plate is to the minimum diameter that also must equal the valve body circumference of the distance of valve plate rotatingshaft, and greater than the distance of rotatingshaft to the both sides screw pair, do not hinder the rotation of valve body top board for the screw pair that makes both sides, will be with the journal stirrup lengthening of screw pair, allow the valve plate top in screw pair, pass through, for the intensity that guarantees journal stirrup also need have stiffening rib, certainly will cause valve body structure to strengthen like this, weight increases, particularly when valve aperture was big, the weight of increase was more considerable.
The utility model adopts two screw pairs 6, valve plate 4 can not be subjected to the obstruction of side screw pair when rotating, therefore the centre distance of two screw pairs can shorten dramatically, the valve body journal stirrup shortens and does not need to use stiffening rib again, the structure length of valve body also shortens greatly, reduce 1/3rd with bore valve consumption material, processing charges reduces 10-15%; Simultaneously, change two screw pairs 6 into after, increase by two auxiliary clamping bolts 7, operate still easily, and make clamping point become four by three, also be provided with sealing gasket 5 at the sealing contact surface place of valve plate, the sealability of valve is more guaranteed.
Specifeca tion speeifications more of the present utility model are:
Inside nominal diameter: DN (mm) 300-1200;
Nominal pressure: PN (Mpa) 0.03-0.15;
Adjusting play: manual 10-20m/m;
Applicable temperature :≤25 ℃;
Applicable media: coal gas.
