Pressure regulator is introduced
Pressure regulator, has also been used as reducer. Its in petrochemical field plays a great role. We know that the liquefied petroleum gas combustion safety is an important component in the cylinder and stove, connectivity between. Voltage regulator not only get the bottle into a low pressure high pressure petroleum gas petroleum gas ( from 980000 Pa to 100000 Pa ), but also the low pressure gas, stable in suitable for stoves combustion safety pressure range. I.e. do the it is the output of the oil gas, stoves fire hole in the air, Suidisuishi than the external atmospheric pressure value of about 2940Pa, so the actual increase pressure regulator is one kind of automatic voltage stabilizing device. Except in the petrochemical industry, which in other places, such as electrical appliances industry, pressure regulator role is very important.
First introduced the downward pressure device specifications meaning, for example: China electric switch factory product TDGC2 contact voltage regulator in a TDGC2-3K. Inside each letter represents the meaning, if you go to have a look on the product page, stick out a mile: T regulator, D represents a single phase, in addition, the general phase number and S, representing the phase, G represents the dry cold, C represents the contact type (ring ), and 3K stands for the rated capacity. So you can understand and direct understanding of a pressure regulator, but in addition to these parameters, common letters and : J: economic type, P represents derived products. Some common technical parameters mainly include: the number of phase, frequency, rated voltage, rated voltage, rated input current. Basically these parameters once identified, will specify a pressure regulator.
Below is the regulator structure, which comprises a hand wheel, intake manifold, valve cover, a lower valve cover, rubber membrane, inlet nozzle, the valve pad, a small lever, outlet pipe and other parts.
Pressure regulator is in the middle of a piece of circular membrane, the pressure regulator is divided into two gas chambers. Gas chamber provided with a spring, whose upper end is connected with the adjusting screw cap, and is connected with a rubber membrane. The upper valve cover is provided with a diameter of 0.8 without m holes, so that the gas chamber is communicated with the outside world, this hole is called a breathing hole. The gas chamber has a fine brass lever, a total length of about 5cm, turning performance is very sensitive. Lever right end and the rubber film center are connected together, the left stick valve pad, closely in the inlet nozzle, to eject the pressurized gas to generate damping effect. The left and the right ends of the fulcrum lever for short distance left right long, is unequal arm lever. Its performance characteristics: on the right end of the lever action of small changes, is bound to the left end of the lever force produces a larger change. In principle, the power amplifier; in effect, increased for high pressure gas damping effect.
To understand the structure, can directly understand the working principle, the working principle and the sliding resistance almost, and not like a transformer . It turns of coils with different load conditions, so the surge is easy to cause spark. At the same time, the main process is as follows, when we opened the cylinder angle valve ( i.e. ventilation switch ), high pressure oil gas through the inlet pipe through the valve pad into the gas chamber. Along with the increase of gas gas chamber, gas chamber pressure will rise, forcing the rubber membrane is convex upward. Gas chamber volume becomes smaller, when the gas chamber pressure is greater than the pressure, the indoor air from the breathing hole slow discharge. Completed pressure regulator a positive process. In this process, the lever moves left, right end, under pressure, so that the inlet nozzle to gradually close, stop gas supply, gas chamber pressure is no longer rising to.
