Detailed description of the invention

Refer to shown in Fig. 1, Fig. 2 and Fig. 3, three-dimensional appearance schematic diagram the most of the present utility model, perspective exploded view of the present utility model and profile status schematic diagram of the present utility model.As shown in the figure: this utility model is a kind of Improvement type diaphragm valve, this diaphragm valve 1 is at least made up of base 11, anticorrosion sleeve 12, capping 13, one solenoid valve cover 14 and at least two elastic partss 15,16.

Above-mentioned carried base 11 is aluminum material, its centre is provided with one first conduction pipe 111, and this first conduction pipe 111 periphery is provided with the first ventilation interface 112, and the end face of this base 11 is provided with and closes this first conduction pipe 111 and primary diaphragm 113 of the first ventilation interface 112, separately this base 11 is provided with a through hole 114 connected with the first ventilation interface 112.

This anticorrosion sleeve 12 is integrated in the inner edge of the first conduction pipe 111, and this anticorrosion sleeve 12 be galvanized iron or other can the material of acid and alkali resistance gas, and the inner ring of this anticorrosion sleeve 12 is provided with a spacing zone 121, and it is provided with matsurface 122 in the outer rim of this anticorrosion sleeve 12, wherein this matsurface 122 is horizontal tangent plane, oblique tangent plane or staggered tangent plane, and be equipped with a ring edge 123 in the apical margin of this anticorrosion sleeve 12, and the bottom surface of this ring edge 123 is resisted against the apical margin of the first conduction pipe 111.

This capping 13 for aluminum material and is combined with base 11, this capping 13 bottom surface is provided with first air chamber 131 corresponding with primary diaphragm 113, and this capping 13 centre is provided with one second conduction pipe 132, and this second conduction pipe 132 periphery is provided with the second ventilation interface 133, and be provided with in the end face of this capping 13 and to close this second conduction pipe 132 and second secondary diaphragm 134 ventilating interface 133, separately this capping 13 is provided with one end and connects with through hole 114 and the trachea 135 of the corresponding secondary diaphragm of another end 134.

This solenoid valve cover 14 is combined with capping 13, and this solenoid valve cover 14 bottom surface is provided with second air chamber 141 corresponding with secondary diaphragm 134.

Two elastic partss 15,16 are respectively arranged between primary diaphragm 113 and capping 13 and between secondary diaphragm 134 and solenoid valve cover 14.In this way, it is combined into an Improvement type diaphragm valve by said structure.

When this utility model is in time making, it is with galvanized iron or other are acidproof, the material of alkali gas makes this anticorrosion sleeve 12 in advance, and this anticorrosion sleeve 12 is arranged in the mould (not shown) making base 11, the most again aluminum feedstock is flow in mould, use the profile molding base 11 and the first conduction pipe 111, first ventilation interface 112 and through hole 114, and make this anticorrosion sleeve 12 be integrated in the first conduction pipe 111 inner edge of base 11, and make the bottom surface of ring edge 123 be resisted against the apical margin of the first conduction pipe 111, and allowing anticorrosion sleeve 12 utilize, the inner edge of its matsurface 122 and the first conduction pipe 111 is firm is engaged, to prevent obscission.

And when using, be in solenoid valve cover 14, to arrange an electromagnetic valve 2 use, and with the external storage barrel of anticorrosion sleeve 12 or the body 3 of Other related equipment (not shown), and carried out snapping by spacing zone 121 and fix.It is to make electromagnetic valve 2 control the start that first and second diaphragm 113,134 carries out being turned on and off simultaneously when start, using as the control of gas and guiding, such as: when electromagnetic valve 2 cuts out, external enter gas and can stop to note formation pressure in first and second air chamber 131,141, allow first and second diaphragm 113,134 close first and second conduction pipe 111,132 simultaneously；Otherwise when electromagnetic valve 2 is opened, can coordinating by through hole 114 and trachea 135, make first and second air chamber 131, pressure in 141 obtains release simultaneously, make first and second diaphragm 113, 134 reset simultaneously, acidity or alkaline gas is allowed to be passed through by anticorrosion sleeve 12, and be transmitted by body 3, and owing to the inner edge of the first conduction pipe 111 is located at by this anticorrosion sleeve 12, therefore, acidity or alkaline gas can be avoided directly to contact with the first conduction pipe 111 of base 11, and then form preferably anticorrosion ability, this makes diaphragm valve 1 can reach increases service life and reduces effect of cost of manufacture.

Refer to shown in Fig. 4, for the perspective exploded view of another embodiment of this utility model.As shown in the figure: this base 11a can be different configuration, and this anticorrosion sleeve 12 can be located in the first conduction pipe 111a of base 11a equally, use the effect reaching same on different base 11a, and then make this utility model required when can more meet actually used.

In sum, Improvement type diaphragm valve of the present utility model is efficiently modified the disappearance of known structure really, available solenoid valve cover collocation electromagnetic valve uses, and control first and second diaphragm switch of start simultaneously, using as the control of gas and guiding, acidity or alkaline gas is allowed to be passed through by anticorrosion sleeve, make diaphragm valve can reach increase service life and reduce effect of cost of manufacture, make this utility model certainly will be more progressive, practical and meet user demand eventually, should possess the basic important document of patent application, propose novel application in accordance with the law.

Only the above, it is only preferred embodiment of the present utility model, the technical scope that this utility model is implemented is limited when not being able to this, the most all simple equivalence changes made with reference to this utility model claims and description book content and modification, all should still belong to this utility model and obtain in the range of patent contained in the future, Chen Ming the most in the lump.
