Abstract
The utility model discloses a flap valve with bellows protection device, according to the problem of a valve damaging because of the injury of the bellows easily caused by the present flap valve under the stress of a valve body and the valve affected by the outside power at a pipe. The utility model includes a right valve body (1), and the right valve body (1) is provided with three support ears (8, 9, 10). The utility model is characterized in that the support ears (8, 9, 10) of the right valve body (1) and one side of the bellows (2) are installed with a caging device with a baffle (11), a positive stop screw (12) and a positive stop base (13). The positive stop base (13) is connected with the corresponding support ears (8, 9, 10), and the positive stop screw (12) is connected through the baffle (11) with the positive stop base (13). The utility model can not only protect efficiently the bellows, but also can adjust conveniently the expansion amount with simple structure and good practical efficiency.
Description
Technical field
The utility model relates to a kind of Flap valve (claiming glasses valve, blank-plate valve again) with bellows protective gear
Background technique
At present, Flap valve is widely used on the pipeline of industrial departments such as metallurgy, oil, chemical industry, coal gas.
Flap valve mainly is made up of left valve barrel, right valve barrel, bellows, turnover panel, leading screw, nut, turnover panel Denso, clamping Denso etc.Left and right two valve bodies and turnover panel are unified into a rigid unitary with three turnbuckle screw pairs, and bellows is located on the right valve, to realize the separation stroke of left and right sides valve body.
Because this kind valve its specific structure characteristics and seal form.Occur some problems in actual applications easily, subject matter appears on this structure of bellows.Its original structure such as Fig. 1.Flange and base that the below will connect bellows weld with steel plate.This structure is not attractive in appearance.And reliability is obviously not enough.When valve body is suppressed, and valve all is easy to pull bellows when influenced by external force, and causing whole valve to damage can't use.
Summary of the invention
The purpose of this utility model is in order to overcome existing Flap valve in the deficiency aspect the bellows protection, to design a kind of turnover panel plate with bellows protective gear.
The technical solution of the utility model is:
A kind of Flap valve with bellows protective gear; comprise right valve barrel 1; right valve barrel 1 is provided with three support ears 8,9,10; it is characterized in that on the support ear 8,9,10 of right valve barrel 1, a side of bellows 2 all is equipped with the limit stoper of being made up of baffle plate 11, spacing screw rod 12 and spacing pedestal 13; spacing pedestal 13 and corresponding support ear 8; 9,10 link to each other, and spacing screw rod 12 passes baffle plate 11 and is spirally connected with spacing pedestal 13.
Described spacing pedestal 13 is welded on the corresponding support ear 8,9,10, and baffle plate 11 is welded on the back side of the flange on the right valve barrel 1.
Described spacing screw rod 12 is a trapezoidal thread.
The utility model is installed limit stoper in a side of right valve barrel 1, bellows 2, adjusts the home at bellows place by the rotation of the screw rod on the snubber, and installs respectively in three places at support ear place.When suppressing or bellows stretches when overstepping the extreme limit, limit stoper is then born restriction by the pulling force that pressure or pipe deforming produced, thereby reaches the purpose of protection valve bellows.
The beneficial effects of the utility model are, when can effectively protect bellows, regulate the extending amount of bellows easily, and are simple in structure, good practical effect.Flap valve needs sealing intensity and body strength are carried out the pressure testing check as the user in the back of dispatching from the factory; owing to there is not the fixing tool of specialty; when doing the test of sealing or valve body; the bellows pressurized; to carry out extensional motion; must pull bad; bellows is as the core component of Flap valve; it also is the some of most fragile; any distortion or damage are arranged; just mean scrapping of whole deck valve door, the utility model can not only effectively be protected bellows, and can easily be to the adjusting of bellows extending amount.Except pressure test, can also prevent because pipe deforming, accidental shock to the infringement of bellows.

Fig. 3 is the structural representation of Flap valve of the present utility model.
Fig. 4 is the left TV structure schematic representation of Fig. 3.
Fig. 5 is the local enlarged diagram among Fig. 4.
Among the figure: the 1st, right valve barrel, the 2nd, bellows, the 3rd, leading screw, the 4th, nut, the 5th, turnover panel, the 6th, left valve barrel, the 7th, base, the 8,9, the 10th, support ear, the 11st, baffle plate, the 12nd, spacing screw rod, the 13rd, spacing pedestal.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in Fig. 3,4,5.
In Fig. 4, flange side (back) the welding baffle plate 11 at right valve barrel at each welded limiting pedestal 13 of a side of support ear 8,9,10, guarantees the concentricity of baffle plate 11 and spacing pedestal 13.Penetrate spacing screw rod 12 by baffle plate 11 1 sides then, spacing screw rod 12 is a trapezoidal thread, and screws in the spacing pedestal 13.Spinning gets final product to the flexible effective coverage of bellows.Protective gear is installed in 3 support ears, 8,9,10 places respectively.3 screwing length will be consistent, and avoids occurring deviator.The size of the length of spacing screw rod 12, diameter and valve aperture, kilogram pressure are directly proportional.
Claims (3)
1. Flap valve with bellows protective gear; comprise right valve barrel (1); right valve barrel (1) is provided with three support ears (8,9,10); it is characterized in that support ear (8,9, the 10) side last, bellows (2) in right valve barrel (1) all is equipped with the limit stoper of being made up of baffle plate (11), spacing screw rod (12) and spacing pedestal (13); spacing pedestal (13) and corresponding support ear (8; 9,10) link to each other, spacing screw rod (12) passes baffle plate (11) and is spirally connected with spacing pedestal (13).
