摘要:
The present Invention relates to a pressure differentiating device used in systems to control smoke and heat spread, wherein the rotational speed governor with the processor (18) has a software that makes it possible to maintain the pre-set pressure difference while identifying the cubature and tightness of the object under control with the use of a neural network structure, and, by this means, the need to calibrate devices each time when the cubature and/or tightness has been changed is eliminated.

The invention solves the problem of energy-free compensation of fluctuations in gas demand in natural gas networks by means of a compression-storage-expansion installation by using a reciprocating compressor (5) driven by gas taken from a medium or high pressure transmission pipeline. The compression-storage-expansion installation may additionally have a gas liquefaction module based on gas expansion (14) and at least one low-temperature tank (17) and a liquid gas evaporator (19). Moreover, it may have measuring-distribution sets for delivering compressed and/or liquefied gas as respectively CNG (12) and/or LNG (20) fuel to the external customers.

The present Invention relates to a method of controlling pressures in vertical escape routes for the purpose of securing vertical escape routes, characterised in that the amounts of supplied and discharged air depend on the temperature value in the vertical escape route 1 and the external temperature, which are transmitted from the temperature sensor 4 located in the vertical escape route 1 and from external temperature sensor 5 into the central control unit 6 , which activates, based on the computed difference of temperatures, the reversible upper fan 7 and the reversible lower fan 8 , as well as the upper pressure-regulating governor 9 and the pressure-regulating governor 10 .

摘要:
A chimney cap comprising an axis, on which a hood is mounted; the hood consists of a body, stabilizer, and a tube-shaped element, wherein, the axis is a double bent rod the bottom section of which is rigidly fixed to the inner edge of the tube-shaped element of the hood seated in the base, and its top section is coincident with the axis of the tube-shaped element of the hood. A chimney cap has a bend in the form of a conical protrusion and has the tube-shaped element of the hood, which is equipped with at least two butterfly latches. The base of the chimney has at least two L-shaped notches to mount the tube-shaped element of the hood using the butterfly latches. The body and the stabilizer are mounted on a double bent rod so that the rotation movement around the axis is possible. The stabilizer is replaceable and has different shapes. The hood has a tail fixed to the body and the size of the clearance between the body and the tail can be adjusted using a butterfly turn button. The hood is hanged on a conically tipped top section of the double bent rod through a bearing-type embedding set, which consists of a washer, two slide bearings and a protective element. Furthermore the hood is equipped with a slide lock to enable the replacement of the stabilizer. The slide lock has a snapping element that is shaped as a spot-wise extrusion.
