Abstract
The utility model relates to a pressure warning unit. The utility model is technically characterized in that: one end of the cylinder block is connected with the pipe joint while the other end is provided with a cylinder head; a piston is positioned inside the cylinder block; the piston-rod which is provided with a spring is positioned in the cylinder head; the tall and the low pressure-restraining tablets according respectively with the high-pressure or the low-pressure warning micro-switches which are fixed on the cylinder block and the cylinder head are positioned on the end; and the high-pressure and the low-pressure warning micro-switches are connected with the alarming bell via the socket on the cylinder head. The utility model has the advantages of simple structure, convenience of debugging and using and no misinformation and suits for the pressure control of the operating equipments and the pressure vessels, making the operating equipments and the pressure vessels safely work under normal pressure.
Description
Affiliated technical field
The utility model relates to a kind of pressure warning unit, belongs to the utensil that monitor pressures changes.
Background technology
Control to chilled water in the Chemical Manufacture is extremely important, as cooling-water pump at when operation unexpected pump shaft or fracture appears in impeller or when damaging, it is zero that its output and pressure can be reduced to suddenly, the air compressor machine of at this moment working and other need the equipment of water quench, can burn because of the unexpected interruption of chilled water, thus influence safety in production and personal safety.Existing cooling water pressure alarm, its sensitivity is very high, the debugging trouble, interim water pressure fluctuations can cause that also connecting rope stops, often so also cause unnecessary loss, so a lot of unit changes artificial supervision into, the people in a post, the lost labor also makes mistakes, inaccurate phenomenon takes place.
Summary of the invention
The purpose of this utility model is: a kind of pressure warning unit is provided, and it has simple in structure, and debugging is convenient, characteristics easy to install.
The technical solution of the utility model is: a kind of pressure warning unit, has cylinder block, cylinder block one end is connected with pipe adapter, the other end is equipped with cylinder cap, it is characterized in that: Packed piston in the cylinder block, its piston rod end places in the cylinder cap, upper cover of piston rod shock mount in the cylinder block, high pressure catch and low pressure catch are housed on the piston rod in cylinder cap, high pressure catch and low pressure catch are corresponding with the high and low pressure warning microswitch difference on being fixed on cylinder block, cylinder cap, and two switches are connected with the alarm bell by the socket that is located on the cylinder cap.
The alarm of present technique can be installed on the operation pipeline or the pressure gauge connection place by pipe adapter, can adopt direct supply 6v or alternating current 220v can, the back is installed rotates the high-low pressure catch or rotate the adjustment that cylinder cap can be realized contact distance.When cooling water pressure was undesired, the variation of pressure was moved piston during work, and the displacement of low pressure catch was connected the low pressure alarming microswitch when pressure was low, sent the warning the tinkle of bells.The wasteful alarm for high voltage microswitch that makes in high pressure catch position was connected when pressure was high, sent the warning the tinkle of bells.Present technique is applicable to the pressure control of various operational outfits and pressure vessel, make they can be in normal pressure limit the work of safety.
Because the pressure warning unit of present technique is simple in structure, installation, debugging, easy to use, does not report phenomenon by mistake, it is that a people keeps three hilllocks that past one people keeps that a hilllock also can change.Practical, cost of products is low and popular to people deeply.
