Abstract
The invention discloses a device for monitoring the pressure between two layers of corrugated pipes or two layers of container shells. The device is characterized by comprising a pressure container sealing device composed of an outer layer container shell body and an inner layer container shell body or a corrugated pipe sealing device composed of an outer layer corrugated pipe and an inner layer corrugated pipe, a pressure monitoring opening connecting pipe is installed on the outer layer corrugated pipe or the outer layer container shell body, and a stainless steel net is arranged between the outer layer corrugated pipe and the inner layer corrugated pipe or between the outer layer container shell body and the inner later container shell body. According to the device, the stainless steel net is arranged between the two layers of corrugated pipes or the two layers of container shells, the mechanical property of the structure of the two layers of corrugated pipes or the two layers of container shells is not influenced, a leaked medium can flow between the two layers without blocking when leakage occurs in the inner layer, the leaked medium can reach the interior of the pressure monitoring opening connecting pipe in time to be monitored by a pressure monitoring device, and the monitoring sensitivity of the pressure between the two layers of corrugated pipes or the two layers of container shells is improved.
Description
Technical field
The present invention relates to a kind of double-ply bellows or double container structure.
Background technology
Gapless between current existing double-ply bellows, when leaking appears in internal layer, the medium of leakage can not be without hindrance mobile between bilayer, can not arrive in time in the adapter of pressure monitoring mouth, can not by pressure monitoring devices, be monitored in time.
Whether current existing two-layer compound container, in order to monitor in time the container internal layer shell, dielectric leakage occurs, usually slot to improve the sensitivity of pressure monitoring in the inside of outer shell of tank, but can be influential to the mechanical property of shell of tank at the shell of tank fluting.
Summary of the invention
Purpose of the present invention is exactly for above-mentioned the deficiencies in the prior art, and the pressure monitoring device between a kind of double-ply bellows or double container housing is provided.
The technical solution used in the present invention is as follows:
Pressure monitoring device between a kind of double-ply bellows or double container housing, it is characterized in that it comprises the bellow seal of sealing means of pressure vessel or outer corrugated tube and the internal layer corrugated tube composition of outer layer container housing and internal layer container housing composition, the pressure monitoring mouth is installed on described outer corrugated tube or outer layer container housing and takes over, between outer corrugated tube and internal layer corrugated tube or between outer layer container housing and internal layer container housing, be provided with stainless steel cloth.
Described pressure monitoring mouth is taken over and is welded on the straight section of outer corrugated tube, and is fixed on pipe nipple by support, and the pressure monitoring mouth is taken over inside and is connected with the gap between the internal layer corrugated tube with outer corrugated tube.
Described pressure monitoring mouth is taken over and is welded on the outer layer container housing, and the pressure monitoring mouth is taken over inside and is connected with the gap between the internal layer container housing with the outer layer container housing.
Beneficial effect of the present invention has:
By between double-ply bellows or two-layer compound shell of tank, stainless steel cloth being set, make when internal layer occur leaking into, the medium leaked can be without hindrance mobile between bilayer, arrive in time in the adapter of pressure monitoring mouth, by pressure monitoring devices, monitored, neither affect the mechanical characteristic of double-ply bellows or two-layer compound structure of container, can improve again the sensitivity of double-ply bellows or the monitoring of two-layer compound vessel shell interlayer pressure.
