Description
Technical field
The utility model relates to a kind of constant-voltage equipment, particularly a kind of pipeline constant-voltage equipment.
Background technique
In the industrial processes, often need the liquid in the pipeline or gas are carried out the constant voltage processing.For example, production material need have constant reaction temperature when the still internal reaction, and for guaranteeing its temperature constant, the water of will just lowering the temperature in practical operation should keep certain pressure, so better control temperature fall time, exact grasp reaction temperature.The general method that adopts is at present, for guaranteeing cooling-down effect, the pump capacity design all surpasses its actual use amount, between main water pipeline and water return pipeline, adorn a pressure-limit valve, meeting releasing pressure automatically when hydraulic pressure surpasses, though such design can be satisfied the production needs, its shortcoming is the running that water pump needs twenty four hours not stop, and causes waste of energy.
The model utility content
The technical problems to be solved in the utility model provides a kind of simple and easy, and pipeline constant-voltage equipment easily can be controlled the working state of water pump according to hydraulic pressure, does not need the water pump long time continuous working, thereby has avoided the waste of the energy.
For solving the problems of the technologies described above, pipeline constant-voltage equipment of the present utility model is made up of water pump, water pump control circuit, intake pipe, return pipe, pressure gauge with electric contact, safety check, pressure-limit valve, water pump links to each other with intake pipe, there is a safety check water pump and intake pipe connection, a pressure gauge with electric contact is housed on the intake pipe, water pump control circuit links to each other with pressure gauge with electric contact, and a pressure-limit valve is housed between intake pipe and return pipe.
Adopt after such structure, the inner pipe water pressure of will intaking if desired is limited in a certain particular range, pressure gauge with electric contact upper and lower force value is transferred to the upper lower limit value of this scope, pressure-limit valve pressure is transferred to a little more than pressure gauge with electric contact upper limit force value, when the water inlet inner pipe water pressure is reduced to pressure gauge with electric contact threshold pression value, the water pump control circuit action, starting mode of pump, the water inlet inner pipe water pressure rises, when the water inlet inner pipe water pressure reaches pressure gauge with electric contact upper limit force value, the water pump control circuit action, water pump is out of service, the water inlet inner pipe water pressure begins to descend, and repeats said process when the water inlet inner pipe water pressure is reduced to pressure gauge with electric contact threshold pression value, realizes water pump running automatically as required.Pressure-limit valve can be under special circumstances, opens when intake pipe hydraulic pressure is too high, guarantees pipe safety.The utility model is simple in structure, and effect is obvious, makes water pump not need long time continuous working by above improvement, thereby has avoided the waste of the energy.
Description of drawings
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
A kind of mode of execution structural representation of a kind of pipeline constant-voltage equipment of Fig. 1 the utility model.
Embodiment
A kind of pipeline constant-voltage equipment shown in Figure 1 is by water pump 2, water pump control circuit 3, intake pipe 5, return pipe 10, pressure gauge with electric contact 1, safety check 4, pressure-limit valve 6, inlet valve 7, drain valve 9 is formed, water pump 2 links to each other with intake pipe 5, water pump 2 has a safety check 4 with intake pipe 5 connections, a pressure gauge with electric contact 1 is housed on the intake pipe 5, a pressure-limit valve 6 is housed between intake pipe and return pipe, intake pipe 5 is equipped with an inlet valve before by reactor 10, intake pipe is equipped with a drain valve 9 after by reactor 10, water pump control circuit 3 links to each other with pressure gauge with electric contact 1.Water pump control circuit 3 is made up of button SB, pressure gauge with electric contact 1 low pressure normally opened contact B2, pressure gauge with electric contact 1 high pressure normally-closed contact B1, contactor KM, pressure gauge with electric contact 1 low pressure normally opened contact B2 is in parallel with normally opened contact of contactor KM, then with button SB, pressure gauge with electric contact 1 high pressure normally-closed contact B1, the series connection of contactor KM coil, normally opened contact of contactor KM is connected on the water pump 2.
When the utility model uses, can earlier inlet valve 7 and drain valve 9 be opened, if desired hydraulic pressure in the intake pipe 5 is limited in a certain particular range, pressure gauge with electric contact 1 upper and lower force value is transferred to the upper lower limit value of this scope, pressure-limit valve 6 pressure are transferred to a little more than pressure gauge with electric contact 1 upper limit force value, when hydraulic pressure in the intake pipe 5 is reduced to pressure gauge with electric contact 1 threshold pression value, pressure gauge with electric contact 1 low pressure normally opened contact B2 closure, the KM coil gets, KM normally opened contact closure, water pump 2 work, hydraulic pressure begins continuous increase in the intake pipe 5, and when hydraulic pressure in the intake pipe 5 reached pressure gauge with electric contact 1 upper limit force value, pressure gauge with electric contact 1 high pressure normally-closed contact B1 disconnected, the KM coil losing electricity, the KM normally opened contact disconnects, and water pump 2 quits work, and hydraulic pressure begins to reduce in the intake pipe 5, when hydraulic pressure in the intake pipe 5 is reduced to pressure gauge with electric contact 1 threshold pression value, repeat said process, thereby realize water pump running automatically as required.Pressure-limit valve 6 can be under special circumstances, opens when intake pipe hydraulic pressure is too high, guarantees pipe safety.Manually stop water pump 2 work if desired, can press the SB button, the KM coil losing electricity, the KM normally opened contact disconnects, and water pump 2 quits work.The utility model is simple in structure, and effect is obvious, makes water pump 2 not need long time continuous working by above improvement, thereby has avoided the waste of the energy.
Above-mentioned pressure gauge with electric contact 1 can be selected YX-100 type pressure gauge with electric contact for use, also can select other products with similar functions for use.
By reference to the accompanying drawings the preferred embodiment of the utility model has been done detailed description above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those skilled in the art possess, can also under the prerequisite that does not break away from the utility model design, make a variety of changes.
