The model utility content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of aluminium film explosion-released valve is provided, and tightness is good, and it is more convenient to change the aluminium lamina membranacea.
For achieving the above object, the technical solution of the utility model has provided a kind of aluminium film explosion-released valve, comprise valve body, the adapter that is connected with a side of described valve body, be arranged at the aluminium membrane module in the described valve body, be arranged at the sealing door closure of described valve body opposite side, described aluminium membrane module is between described adapter and described sealing door closure, and described aluminium membrane module comprises the flange connecting pipe that is fixedly connected with described valve body, be embedded in the pressure-bearing Mild Steel Expanded Sheets on the described flange connecting pipe, be layed in the aluminium lamina membranacea on the described Mild Steel Expanded Sheets, be arranged at the supported flange on the described aluminium lamina membranacea.
As preferably, the thickness of described aluminium lamina membranacea is 0.5-2mm.
As preferably, described supported flange, described aluminium lamina membranacea, described flange connecting pipe three are fixedly connected with by bolt, nut.
As preferably, described sealing door closure comprises the pull bar that door body, an end and described door body are fixedly connected, and the other end of described pull bar rotates with described valve body and is connected.
As preferably, described valve body comprise valve body, with the hanger that described valve body is fixedly connected, the other end of described pull bar rotates with described hanger and is connected.
As preferably, be provided with the first sealing gasket between described adapter and the described valve body.
As preferably, be provided with the second sealing gasket between described flange connecting pipe and the described valve body.
Advantage of the present utility model and beneficial effect are: be inlaid with the pressure-bearing Mild Steel Expanded Sheets on the flange connecting pipe, the aluminium lamina membranacea is layed on the Mild Steel Expanded Sheets, and the aluminium lamina membranacea is had enough support forces, aluminium lamina membranacea difficult drop-off, and be provided with supported flange on the aluminium lamina membranacea and compress the aluminium lamina membranacea, prevent the gas leakage of aluminium lamina membranacea, tightness is good.
Description of drawings
Fig. 1 is the utility model schematic representation;
Fig. 2 is the A place enlarged view of Fig. 1;
Fig. 3 is the sectional view of aluminium membrane module.
Among the figure: 1, take over; 2, flange connecting pipe; 3, Mild Steel Expanded Sheets; 4, aluminium lamina membranacea; 5, supported flange; 6, door body; 7, pull bar; 8, hanger; 9, the first sealing gasket; 10, the second sealing gasket; 11, valve body.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1-Figure 3, a kind of aluminium film explosion-released valve, comprise valve body, the adapter 1 that is connected with a side of described valve body, be arranged at aluminium membrane module in the described valve body, be arranged at the sealing door closure of described valve body opposite side, described aluminium membrane module is between described adapter 1 and described sealing door closure, and described aluminium membrane module comprises the flange connecting pipe 2 that is fixedly connected with described valve body, be embedded in pressure-bearing Mild Steel Expanded Sheets 3 on the described flange connecting pipe 2, be layed in aluminium lamina membranacea 4 on the described Mild Steel Expanded Sheets 3, be arranged at the supported flange 5 on the described aluminium lamina membranacea 4.Wherein take over 1 and be used for being connected with the apparatus body of needs installation explosion-released valve, can be by being welded to connect.Both polish flange connecting pipe 2 and Mild Steel Expanded Sheets 3 by after being welded to connect, and the sealing door closure relies on self gravitation that aluminium film explosion-released valve is carried out the effect of secondary seal, prevent because of the aluminium lamina membranacea 4 local compression degree phenomenon that leaks air not.
Without diagram, the thickness of described aluminium lamina membranacea 4 is 0.5-2mm.During use, need to determine according to the pressure of venting of dust explosion the thickness of aluminium lamina membranacea 4.
As shown in Figure 3, described supported flange 5, described aluminium lamina membranacea 4, described flange connecting pipe 2 threes are fixedly connected with by bolt, nut.
As shown in Figure 1 and Figure 2, described sealing door closure comprises the pull bar 7 that door body 6, an end and described door body 6 are fixedly connected, and the other end of described pull bar 7 rotates with described valve body and is connected.
As shown in Figure 1 and Figure 2, the hanger 8 that described valve body comprises valve body 11, is fixedly connected with described valve body 11, the other end of described pull bar 7 rotates with described hanger 8 and is connected.
As shown in Figure 2, be provided with the first sealing gasket 9 between described adapter 1 and the described valve body, be provided with the second sealing gasket 10 between described flange connecting pipe 2 and the described valve body.Described the first sealing gasket 9 is asbestos with described the second sealing gasket 10.
Working principle: when normally moving, equipment is in negative pressure state, at this moment, aluminium lamina membranacea 4 under negative pressure state tightly docile on pressure-bearing Mild Steel Expanded Sheets 3, sealed door is built the effect of secondary seal, when abnormal conditions occurring, cause raising with taking over the 1 apparatus body internal pressure that is connected, reach the limit value that device security allows, at this moment, aluminium lamina membranacea 4 center stresseds reach its yield limit firmly, and aluminium lamina membranacea 4 outwards breaks through fast, broken opening in the middle of the aluminium lamina membranacea 4, discharge unnecessary pressed gas to the outside, the sealing door closure is opened rapidly under the effect of the gas that discharges, and discharges unnecessary pressed gas, when equipment pressure returns to normal state, door body 6 is leaned on the jail with valve body 11 again mutually under the self gravitation effect, equipment restarts normal operation, and broken aluminium lamina membranacea 4 need to be changed when overhaul of the equipments.
