Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Figure 1 shows that the structural representation of the utility model constant temperature and pressure water system, described constant temperature and pressure water system comprises water tank 1, liquid level detector 2, first temperature pick up 3, strainer 4, first stop valve 5, water pump 6, one way valve 7, accumulator 8, Pneumatic diaphragm valve 9, PLC 14.
Water tank 1 is for water storage, and water tank 1 is connected with tap water pipe line 12 and steam pipework 13, steam pipework 13 is provided with Pneumatic diaphragm valve 9, and whether steam injects is controlled by Pneumatic diaphragm valve 9.Water tank 1 is also provided with the liquid level detector 2 for detecting cistern water level and the first temperature pick up 3 for sensing supply water temperature, Pneumatic diaphragm valve 9, liquid level detector 2 are connected with PLC 14 with the first temperature pick up 3.When supply water temperature is too low, signal can be reached PLC 14 by the first temperature pick up 3, and PLC 14 is through computing output feedback signal, and open Pneumatic diaphragm valve 9, steam enters water tank 1 with heating tap water; Otherwise when supply water temperature is too high, Pneumatic diaphragm valve 9 steam off, stops heating.
Liquid level detector 2 is installed below water tank 1, for detecting water tank surplus water, at water outlet, the first pressure sensor 15, strainer 4 and the first stop valve 5, first pressure sensor 15 is installed simultaneously and is connected with PLC 14.Pressure meter 15 is for detecting water pressure, and strainer 4, for filter feeding, prevents foreign material blocking pipe, and the first stop valve 5, for segmentation pipeline, facilitates daily segmental inspection, cleaning, replacing.First stop valve 5 is connected with two branch lines in parallel, and each branch line is provided with the second stop valve 16, water pump 6, one way valve 7, and water pump 6 is connected with PLC 14.Supply water in two branch line one roads, one tunnel is for subsequent use, water pump 6 is by the Frequency Converter Control be connected with PLC 14, the size of hydraulic pressure is controlled by pump motor rotating speed, the rotating speed of pump motor is then controlled by the output frequency signal of frequency converter, and the output signal of frequency converter then gathers by the first pressure sensor 15 of feed water inlet the input signal come and controls.One way valve 7 is for anti-backflow.
The delivery port of two branch lines is connected with supply channel, and the upper end of supply channel connects accumulator 8, stores pressure energy, when the too small release pressure of hydraulic pressure can supplement deficiency when hydraulic pressure is excessive.The second pressure sensor 10, second temperature pick up 11 be connected with PLC 14 is installed in the lower end of supply channel.
Operating principle of the present utility model: when applying, the water temperature of water tank 1 comes from the heat trnasfer of steam, and hydraulic pressure comes from the mechanical energy of water pump 6, and tap water injects above water tank 1, steam also injects from top simultaneously, to tap water heating (i.e. warm).(requirement of liquid level detector 2 and the first temperature pick up 3 is reached) after preheating completes, tap water under the effect of water pump 6 through water outlet of water tank, filtered by strainer 4, enter in water pump 6 through stop valve 5 again, when water pump 6 or the pipeline exception of one of them branch line, spare duct can be enabled at any time, the tap water now with uniform temperature and pressure enters accumulator 8 place pipeline after one way valve 7, accumulator 8 can absorb a part of pressure energy when hydraulic pressure is excessive, when hydraulic pressure is too small and when having exceeded the scope that water pump can regulate, energy release pressure energy, supplement the deficiency of hydraulic pressure, especially the initial and ending phase supplied water, effectively can play regulating action.Tap water is again through the first temperature pick up 3 to equipment supply channel, now water temperature hydraulic pressure reaches the stabilization sub stage substantially, PLC 14 can constantly control according to gathering the rotating speed of signal to the opening and closing of Pneumatic diaphragm valve 9 and water pump 6 come simultaneously, thus finely tunes water temperature hydraulic pressure.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
