Description
technical field:
The utility model relates to a kind of safety valve sealing structure.
background technique:
Safety valve is a kind of releasing pressure automatically protective equipment opened by import static pressure, it is one of of paramount importance safety attachment of pressurized container, its function is: when container inner pressure exceedes certain certain value, relies on the automatic Open valve of pressure of medium self, discharges rapidly the medium of some.When the pressure in container drops to permitted value, valve cuts out again automatically, makes container inner pressure all the time lower than the upper limit of authorized pressure, automatically prevents the accident that may occur because of superpressure, the final protective gear of pressurized container so safety valve is otherwise known as.The non-return of internal security valve, in let out be all withstand silica gel flat gasket and the axial seal of copper piece arc surface by guide pillar, this mode has shortcomings: 1. arc surface is not easily processed and caused non-return effect bad; 2. silica gel easily ftractures when doing life test; 3. let out the fluctuation of tapered spring force value in comparatively large, inside let out pressure instability; 4. structure is not easily assembled, and brings very large puzzlement in the use of existing product, concrete as Fig. 1.
summary of the invention:
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of safety valve sealing structure.
The utility model is achieved through the following technical solutions:
A kind of safety valve sealing structure, comprise the safety valve housing with import, described enclosure interior is provided with the connecting plate, guide pillar, the big spring that match, guide pillar bottom is connected with the lid top for shutoff import, it is characterized in that: the passage described lid offering UNICOM's safety valve inner chamber and lid inner chamber, described lid opening is connected with the cover plate with through hole and port, the guide rod be mated is connected with in described through hole, described guide rod upper end is provided with the plug for shutoff passage, is positioned on the guide rod between plug and cover plate and is provided with spring.
In the utility model embodiment, the plug perisporium being positioned at lid inner chamber is provided with the second annular groove, is provided with the second seal ring for shutoff passage in described second annular groove.
In the utility model embodiment, the counterbore that described lid inner chamber is differed by two apertures is laminated, and the counterbore of smaller aperture due is positioned at upside and is connected with passage.
In the utility model embodiment, described lid lower outer periphery wall is provided with first ring connected in star, is provided with the first seal ring for shutoff import in described first ring connected in star.
In the utility model embodiment, the face that described shell inner cavity matches with the first seal ring is inclined-plane.
In the utility model embodiment, the face that described lid inner chamber matches with the second seal ring is inclined-plane.
In the utility model, advantage is compared with prior art:
1. body processing is simple, enhances productivity, and reduces cost of production; 2. adopt seal ring sealing, seal more stable; 3. pressure release is stablized easy to control; 4. assembling is simple; 5. problem of Cracking during solution silica gel life test.

embodiment:
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below:
A kind of safety valve sealing structure, comprise the safety valve housing 1 with import 11, described enclosure interior is provided with the connecting plate 2 matched, guide pillar 3, big spring 4, guide pillar bottom is connected with lid 5 top for shutoff import, guide pillar is spacing can move up and down on connecting plate, spring housing is connected on guide pillar, above-mentionedly be prior art, set forth no longer one by one secondary, described lid 5 offers the passage 51 of UNICOM's safety valve inner chamber and lid inner chamber, described lid opening is connected with the cover plate 6 with through hole 61 and port 62, cover plate 5 is for being fixedly connected on lid inner chamber perisporium, can by strong button, welding, the mode such as to be spirally connected realizes, the guide rod 7 be mated is connected with in described through hole, described guide rod 7 upper end is provided with the plug 8 for shutoff passage, be positioned on the guide rod 7 between plug and cover plate and be provided with spring 9.
The plug perisporium being positioned at lid inner chamber is provided with the second annular groove 81, is provided with the second seal ring 82 for shutoff passage in described second annular groove.
The counterbore 52 that described lid inner chamber is differed by two apertures is laminated, and the counterbore of smaller aperture due is positioned at upside and is connected with passage, briefly: lid inner chamber is a shoulder hole.
Described lid lower outer periphery wall is provided with first ring connected in star 53, is provided with the first seal ring 54 for shutoff import in described first ring connected in star.
The face that described shell inner cavity matches with the first seal ring is inclined-plane.
The face that described lid inner chamber matches with the second seal ring is inclined-plane, and this inclined-plane is positioned at the intersection of two counterbores.
The concrete working procedure of the utility model matches with itself and water heater and is combined into example: when toward safety valve import water flowing, hydraulic pressure backs down lid, to water heater water flowing, and concrete reference drawing 4; When water heater internal pressure is greater than entrance point pressure, inside water pressure backs down the water route UNICOM of plug on guide rod and import, realizes pressure release, protection water heater, concrete reference drawing 5; When feed-water end hydraulic pressure is equal with water heater hydraulic pressure, guide pillar and lid reset by spring force, formed seal with shell, block water inlet, concrete reference drawing 6.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
