Again further, described baffle plate is ring baffle, and along being connected with the outer of valve gap in it, cross section is the downward arc of concave surface, and the outer of arc is lower than interior edge; The outer of described baffle plate is connected with valve seat.Baffle plate is fully fitted the upper end of convex elastomer diaphragm deformation track, stops the respond well of convex elastomer diaphragm, and can not damage convex elastomer diaphragm, extend its life-span.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model in its natural state, the convex surface of convex elastomer diaphragm and rib and base obstruct closed, namely sealing state is in, avoid traditional scheme and need repeatedly repair in kind in the fabrication process, could design data be determined, cause the problem that design difficulty and manufacture cost significantly increase.
(2) vacuum is deposited in vacuum storage of the present utility model, and outlet is connected with vacuum tube, and in switching process of the present utility model, outside provides negative pressure of vacuum, makes the utility model realize the process of recloser.
(3) the utility model reduces the size of valve gap, increase the thickness of convex elastomer diaphragm, and on valve gap, be provided with the baffle plate of restriction convex elastomer diaphragm deformation, reduce the deformation degree of convex elastomer diaphragm, add the stability of convex elastomer diaphragm deformation, and the design of the special construction of baffle plate, stop the respond well of convex elastomer diaphragm, and convex elastomer diaphragm can not be damaged, extend its life-span.
(4) the utility model is compared with traditional vacuum diaphragm valve, eliminate as convex elastomer diaphragm provides the guides stem of guide-localization, avoid valve body to block in switching process timing barrier and loaded down with trivial details lubrication operation, make vacuum diaphragm valve structurally more simple, reduce manufacture cost and in use convenient reliably, the longer service life of I& M.

Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in further detail, but mode of execution of the present utility model is not limited thereto.
Embodiment
As depicted in figs. 1 and 2, a kind of vacuum diaphragm valve of simple structure, comprise valve seat 1, to be connected with valve seat by lock screw 10 and to form the valve gap 2 of valve body with valve seat, the fluid passage 3 that can mutually circulate is respectively equipped with at the two ends of valve seat, one for flowing to passage, another is flow pass, base stalk 4 is provided with between two fluid passages, and obstruct closed in its natural state with base, make the two trapped convex elastomer diaphragms in fluid passage 5 and be located at the rib 6 of convex surface of convex elastomer diaphragm, the outer of described convex elastomer diaphragm and rib is connected with the interior edge of valve seat, in the present embodiment, the convex surface of convex elastomer diaphragm down, concave surface is installed in valve body upward, valve body is the cylindrical structural of hollow.
In the present embodiment, convex elastomer diaphragm moves up and down and forms deformation track, is provided with vacuum storehouse 7, correspondingly, valve gap is provided with vacuum passage mouth 8 in the concave surface upper end of convex elastomer diaphragm; Flow pass is also connected with vacuum tube.
In order to reduce the deformation degree of convex elastomer diaphragm, increase the stability of convex elastomer diaphragm deformation, reduce the size of valve gap, and on valve gap, be provided with the baffle plate 9 of restriction convex elastomer diaphragm deformation, and in the present embodiment, baffle plate is ring baffle, along being connected with the outer of valve gap in it, cross section is the downward arc of concave surface, and the outer of arc is lower than interior edge, fully the upper end of laminating convex elastomer diaphragm track, stop the respond well of convex elastomer diaphragm, and can not damage convex elastomer diaphragm, extend its life-span, the outer of baffle plate is connected with valve seat.
In the present embodiment, increase the thickness of convex elastomer diaphragm, the effect reached is the deformation degree in order to reduce convex elastomer diaphragm equally.
The utility model is compared with traditional vacuum diaphragm valve, eliminate as convex elastomer diaphragm provides the guides stem of guide-localization, avoid valve body to block in switching process timing barrier and loaded down with trivial details lubrication operation, make vacuum diaphragm valve structurally more simple, reduce manufacture cost and in use convenient reliably, the longer service life of I& M.
