Abstract
The utility model relates to a blind plate valve which comprises two valve bodies and a valve plate. Each valve body comprises a cylindrical barrel body, and both ends of the cylindrical barrel body are respectively provided with flanges and seal plates. A guard ribbed slab group which is welded into a whole by a support lug and a guard plate rib is connected with the outer wall of the barrel body. The valve body also comprises a transition connecting plate. The transition connecting plate which is positioned outside the barrel body is fixedly welded with the outer wall of the barrel body at the position corresponding to the support lug. The guard ribbed slab group is connected and fixed with the transition connecting plate at the support lug point by a detachable and movable connection component. The processing step of the blind plate valve is simple, time and labour can be saved, the cost can be saved, the life time is long and the maintenance is convenient. The utility model is suitable for industries such as chemical industry, metallurgy, petroleum, etc., and can be used for the absolute isolation of two systems.
Description
Technical field
The utility model relates to a kind of valve, especially for a kind of blank-plate valve in the gas pipeline.
Background technique
Blank-plate valve also claims Flap valve, glasses valve, is used for the industry that oil, chemical industry, generating etc. have the continuous process operation, realizes the absolute isolation of a system and another system, so that processing accident or other accident.
The tradition blank-plate valve comprises two valve bodies, a valve plate, every valve body comprise two ends have respectively flange and sealing plate cylindric cylindrical shell, by journal stirrup with protect the outer wall place that protects gusset group and cylindrical shell that gusset is welded as a whole and weld.Its valve body is the integral solder structure, and its processing method mainly contains two classes: a class be with have undressed cross flange, sealing plate cylindrical shell and journal stirrup, protect gusset and weld together, process flange, sealing plate then, thus overcome sealing plate welding deformation; Another kind of be with have processed flange, sealing plate cylindrical shell and journal stirrup, protect gusset and weld together.The former increased processing flange, sealing plate the diameter that is installed, can not overcome owing to the welding journal stirrup, protect the stress that gusset produces, make sealing plate, flange produces in long-term using process and is out of shape; The latter make sealing plate, flange, cylindrical shell be before use just because of welding stress produces bigger distortion, in use further produces distortion.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of transition connecting plate of utilizing will protect gusset group and the joining blank-plate valve of cylindrical shell by movable connecting mode, can overcome the welding deformation of valve body in traditional blank-plate valve, can reduce the valve body processing cost, and valve body in use can not produce distortion yet.
It is to be achieved by following technological scheme that the utility model will solve above-mentioned technical problem: a kind of blank-plate valve, comprise two valve bodies, a valve plate, every valve body comprise two ends have respectively flange and sealing plate cylindric cylindrical shell, by journal stirrup with protect the gusset group of protecting that gusset is welded as a whole and connect with the outer wall of cylindrical shell, described valve body also comprises transition connecting plate, transition connecting plate be positioned at cylindrical shell outer with the corresponding position of journal stirrup and and the outer wall of cylindrical shell weld and fix, protect gusset group and transition connecting plate and be connected and fixed by dismountable active connection at the journal stirrup place.
Described dismountable active coupling is bolt, nut assembly.
The compared with prior art obtained technological progress of the utility model is: because in the middle of the course of working of valve body, process flange, the sealing plate of cylindrical shell earlier, to protect the gusset group again and connect, thereby reduce to process the diameter that is installed, greatly reduce the processing cost of valve body with transition connecting plate; To have in addition processed flange, sealing plate, the cylindrical shell of transition connecting plate adopts the dismountable movable connecting mode of bolt and nut to connect with protecting the muscle journal stirrup, eliminated in the traditional diamond-making technique issuable sealing plate in the welding process, the distortion of flange.Have processed flange, sealing plate body tube and journal stirrup, protect the mode that gusset employing activity connects and connect, avoided the cylindrical shell group and protected welding stress between the gusset group, make sealing plate, can not be out of shape in the long-time using process of flange.
The blank-plate valve of said structure provided by the utility model is after corresponding component processing is finished, and carry out activity and connect, so manufacturing procedure is simpler than original welding manner, time saving and energy saving, saves cost, long service life and dismounting and easy to maintenance.This blank-plate valve is applicable to industries such as chemical industry, metallurgy, oil, is used for the absolute isolation of two systems.
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

Embodiment
A kind of blank-plate valve as shown in Figure 1 is made up of two valve bodies 1, a valve plate.
As Fig. 2--shown in Figure 7, valve body 1 with the cylindrical shell 2 of cylinder type as main body, be connected with flange 3 and the sealing plate 4 that is complementary with cylindrical shell 2 respectively at cylindrical shell 2 two ends, cylindrical shell 2 peripheries are located to be provided with between flange 3 and sealing plate 4 and are three journal stirrups 6 that equilateral triangle distributes, and this equilateral triangle is slightly larger than the external equilateral triangle of cylindrical shell 2; Every journal stirrup 6 is positioned at the bight of equilateral triangle; Journal stirrup 6 serve as reasons along one section radius of cylindrical shell 2 outer walls be slightly larger than cylindrical shell 2 the circular arc limit, slightly cut the concave plane shape that the formed straight line of its drift angle is formed along two straight lines on equilateral triangle limit, equilateral triangle, and journal stirrup 6 is positioned at along cylindrical shell 2 plane radially, has a breach 7 between two journal stirrups.
The sideline of crossing the equilateral triangle at journal stirrup 6 places is provided with protects gusset 8, protecting gusset 8 is positioned at the edge at place, equilateral triangle sideline and two journal stirrups is striden across breach 7 through adjacent two journal stirrups and be connected in one, protect gusset 8 and be positioned at perpendicular plane, plane with journal stirrup 6 places, it extends to nearly sealing plate 4 directions from journal stirrup 6 edges.
Three journal stirrups 6 and its corresponding three protect gusset 8 compositions and protect the gusset group.
Protecting the gusset group links by bolt and nut component 9 and the transition connecting plate 5 that is welded on cylindrical shell 2 outer walls.
Claims (2)
1, a kind of blank-plate valve, comprise two valve bodies, a valve plate, every valve body comprise two ends have respectively flange and sealing plate cylindric cylindrical shell, the outer wall that protects gusset group and cylindrical shell that is welded as a whole by journal stirrup and backplate muscle links, it is characterized in that: described valve body also comprises transition connecting plate, transition connecting plate be positioned at cylindrical shell outer with the corresponding position of journal stirrup and and the outer wall of cylindrical shell weld and fix, protect gusset group and transition connecting plate and be connected and fixed by dismountable active connection at the journal stirrup place.
2, a kind of blank-plate valve according to claim 1 is characterized in that: described dismountable active coupling is bolt, nut assembly.
