Abstract
The utility model relates to a negative-pressure resistant anticorrosive lining product, comprising a shell 2 and a lining layer 1. The utility model is characterized in that the shell is provided with a plurality of through holes 6; a jacket 3 is added on the outside of the shell with a plurality of holes; a cavity 5 is left between the jacket and the shell; the cavity 5 is communicated with a hole 6; an air pumping nozzle 4 is arranged on the jacket. The inner cavity of the jacket is in the high vacuum state at all times through a vacuum pumping device. Consequently, the lining layer 1 in the negative-pressure operating state is in the positive-pressure state corresponding to relative to the high-vacuum cavity, and is tightly struck on the shell to avoid inward flat by suction. The utility model can be used for the large scale devices of the high negative-pressure tower, the pot, the tank, the slot, etc., the pipeline and the fitting, the venturi pipe, and various unit operating devices.
Description
The utility model relates to the corrosion protective lining product of ability negative pressure.
At industrial departments such as chemical industry, oil refining, light industry, metallurgy, the etching problem of producing equipment is very outstanding.A kind of way that addresses this problem is to use resistant material, and for example polytetrafluoroethylene (PTFE) is made the straticulation lining, is enclosed within the housing made from iron and steel or other material, becomes the product of band corrosion protective lining.This product has both corrosion-resistant and withstand voltage premium properties, but has the not defective of anti-negative pressure, and product size is big more, and operating temperature is high more, and this defective is just obvious more.Thereby produce the occasion of negative pressure state in negative-pressure operation or misoperation, and often cause backing layer flat in being inhaled, cause device interior to stop up, destroy ordinary production.
The purpose of this utility model is to provide a kind of corrosion protective lining product that can anti-negative pressure, makes it in negative pressure, especially operate as normal under the high negative pressure duty.
The utility model solution is to open many holes on the housing of corrosion protective lining product, outside housing, add between chuck And and chuck and the housing and leave cavity, by vacuum extractor or automatic control negative pressure adjusting device, make the chuck inner chamber remain stable high vacuum state, each one of backing layer is inhaled firmly by each hole be attached on the perforated shell, and can not inhaled flat by the negative-pressure operation of inside.
Based on above-mentioned design, the utility model provide following examples ， And in conjunction with the embodiments and accompanying drawing summary of the invention is described in detail.
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
This corrosion protective lining product comprises housing 2 and backing layer 1, and backing layer can be made of general anti-corrosion engineering plastics such as fluoro-containing plastics such as polytetrafluoroethylene (PTFE), polypropylene or other anti-corrosion nonmetal and metal material.It is characterized in that having on the housing a plurality of through holes 6, be added with chuck 3 in the outside of perforated shell, leave cavity 5 between chuck and the housing, cavity 5 and hole 6 communicate, the mouth 4 of bleeding on the chuck 3.Housing is made by stephanoporate steel plate or other sturdy material, and chuck is also made ， And with steel plate or other material and with welding or adhering method they linked into an integrated entity.Chuck generally is advisable with 10 millimeters to 100 millimeters to cavity thickness 〉=1 of housing millimeter, decides on specific product.
Certainly, the utility model can have the automatic control negative pressure adjusting device in the lump, and at this moment, the mouth 4 of bleeding that is positioned on the chuck is connected with the automatic control negative pressure adjusting device.For not having the automatic control negative pressure adjusting device, in use, the vacuum available pump is received on the mouth of bleeding and is vacuumized, thereby make the chuck inner chamber remain high vacuum state.
Because housing has porous, be in high vacuum state at setting of housing outside and chuck And and the chuck inner chamber that housing keeps certain space, thereby make the backing layer that is in the negative pressure duty cavity, be in barotropic state with respect to condition of high vacuum degree, even thereby lining be in the negative pressure duty, also can be attached to tightly on the perforated shell, the negative-pressure operation of reason internal work medium and flat in being inhaled not causes that product is inner to be stopped up, and influences operate as normal.
The utility model can be used as main equipment, pipeline and accessory, Venturi tube and various unit operating equipments such as the tower, still, jar, groove of high negative pressure.
Claims (3)
1. a negative pressure-resisting corrosion-resisting lining comprises housing 2 and lining 1, it is characterized in that housing 2 has a plurality of through holes 6, is added with chuck 3 in the outside of perforated shell, leaves cavity 5 between chuck and the housing, and cavity 5 communicates with hole 6, the mouth 4 of bleeding on the chuck.
2. negative pressure-resisting corrosion-resisting lining according to claim 1 is characterized in that chuck is to cavity thickness 〉=1 of housing millimeter.
3. negative pressure-resisting corrosion-resisting lining according to claim 1 and 2 is characterized in that this product has the automatic control negative pressure adjusting device, and the mouth of bleeding on the chuck is connected with the automatic control negative pressure adjusting device.
