Self-operated pressure regulating valve is a type of self-operated regulating valve, because it does not need other external energy sources such as power and gas source, and is driven by the energy of the medium alone, which is energy saving, environmental friendly, easy to use and set pressure after installation The value can be put into automatic operation, so less demanding on the control accuracy, but also the lack of power, gas source of the occasion, has been more widely used. However, self-pressure regulating valve also need the correct selection and installation, use, in order to ensure that put into operation without any problems. Needless to say on the selection, such as the control valve is used to control the pressure before or after the valve pressure, the medium is room temperature or high temperature, whether corrosive, the maximum working pressure, etc., we must first figure out, we mainly talk about Talk about the installation and use of the issue. Because I recently encountered a case of self-service pressure regulator valve problems, very representative. Valve is used in the steam pipe, put into use just a month or two, the user on repair. A look to the scene, a lot of steam from the diaphragm vent valve discharge, noise, amazing momentum. The cause of the accident, obviously, the steam has not been condensed, directly into the membrane head, burned the diaphragm. Self-acting pressure regulating valve for steam pipe, the installation must be between the actuator and the pipe plus a condensate tank, the steam can not get into the actuator membrane, and, the control valve must be installed head-down, condensate tank to be higher than Film head, initial use, be sure to condense the tank and film head filled with water. Look at the installation site, on-site instrumentation staff, these are no problem, then what caused it? It is puzzling. Later, I carefully asked an operator, who inadvertently learned: This valve is installed, put into use, the condensate tank and the film between the brass fittings has been intermittently leaking. The original is the case, the water leakage led to the condensate tank slowly leak light, steam into the membrane head, burned the diaphragm. Thus, self-acting pressure regulating valve in the steam pipe when used, installation, maintenance must pay more attention to, in order to ensure the normal operation of the control valve, do not allow joints leaks, condensation can not be allowed to water, regular inspections, Timely water. In fact, not only self-pressure regulator, is the other self-regulating valve, also need to pay attention to the use of maintenance and care Caixing. In addition, if the steam pressure is higher, the best choice of piston actuators, rather than take the film actuator, because the diaphragm can withstand the pressure of not more than 0.4Mpa, though this can be used, but must greatly reduce the service life.
Turn-out Baler Machine
The turn-out scrap Metal Baler machine is used to compress scrap metal (steel, copper, aluminum, stainless steel, etc)into metal block or metal bale. The purpose is to save the transportation cost or reduce the raw material loss when smelting.
After compressing, the metal bale is easy to transport and store, so it can save transporation cost, reduce storage area and reduce the loss when smelting. Easy operation, durable and long service life, high efficiency, etc.
1) Hydraulic drive, compact design, great sealing;
2) Customized press box size and bale size;
3) Bale discharging ways include turn-out, side-push out and forward-out;
4) Designed with quick unit that can improve work efficiency substantially;
5) Famous motor, hydraulic system, oil cylinder, piston pump, electrical components;
6) Blades: our scrap metal baler machine with the knife, it can cut the long size material when compressing, so it very goog for the long steel wire and big size material.
