Abstract
The utility model discloses an orifice leakage detecting device for an electric heating tube of an inner container of a solar water heater, which comprises a sealed tank, an air pipe and a vacuum pump. One end of the air pipe is connected with the sealed tank, and the other end of the air pipe is connected with an air suction port of the vacuum pump. Water leakage of the electric heating tube orifice is detected by changing air pressure of two sides of the electric heating tube orifice on the inner container, and water test for leakage detecting is not needed. Therefore, mounting the electric heating tube before detecting is more effective in leakage detection than water test for leakage detecting. The electric heating tube orifice does not need to be sealed additionally before detection, and the orifice leakage detecting device is convenient in detection and high in detection efficiency. Further, the orifice leakage detecting device is simple in structure and convenient in operation.
Description
Technical field
The utility model relates to a kind of mouth of pipe leakage detection apparatus, particularly a kind of electrical heating mouth of pipe leakage detection apparatus of solar water heater liner.
Background technology
For guaranteeing that solar water heater can use at rainy weather; General solar water heater all is furnished with the electrical heating supplementary energy, need detect weld seam and the electrical heating mouth of pipe and the electrically heated junction of the electrical heating mouth of pipe and inner bag welding to the electrical heating mouth of pipe leak detection of solar water heater liner aborning; Present leak hunting method is through the leak detection of trying the water; Because electronic devices and components can not direct contact water, if the electrical heating mouth of pipe leaks, water can get into inner bag from the electrical heating mouth of pipe and damage electronic devices and components in the process of trying the water; Therefore electrical heating must be installed in the back of trying the water in process; In order to check trying the water to hunt leak before the sun power inner bag installation electrical heating, mainly mode elder generation installs electrically heated position installation O-ring seal, on O-ring seal, adds gland bonnet then at the electrical heating mouth of pipe on the inner bag at present, through hexagon socket head cap screw gland bonnet is fastened on the electrical heating mouth of pipe again; Again the position at electric heating tube mouth place on the inner bag is immersed in the water; To the logical pressure-air of inner bag, if there is bubble to judge that the electrical heating mouth of pipe leaks in the water, if there is not bubble to judge that the electrical heating mouth of pipe is water-tight.Again with bolt, the gland bonnet dismounting was installed electrical heating, then so still there is the risk of leaking in electrically heated installation site after the leak detection of trying the water finished.This kind mode has greatly influenced production efficiency, is not suitable for mass industrialized production.
Summary of the invention
The utility model technical matters to be solved is: a kind of electrical heating mouth of pipe leakage detection apparatus of solar water heater liner is provided, it can be hunted leak to the electrically heated electrical heating mouth of pipe is installed.
In order to solve the problems of the technologies described above, the utility model comprises sealable tank, tracheae and vacuum pump, and tracheae one end connects sealable tank, and the other end of tracheae connects the air entry of vacuum pump.
For the ease of control; Described vacuum pump is connected with the controller of control vacuum pump work; Controller comprises the time relay of control system break-make power supply of relay I and relay II and pilot relay I of motor and the transformer input end break-make of transformer, control vacuum pump, and controller also comprises the foot-switch of while pilot relay I, relay II and time relay three's control system break-make power supply.
For easy to operate, described foot-switch is a normally closed switch, and the described time relay is normally closed and the relay of time closing.
The beneficial effect of the utility model: whether the utility model detects the electrical heating mouth of pipe through the air pressure of electric heating tube mouth both sides on the change inner bag and leaks; The leak detection of need not trying the water; Therefore, can before detection, install electrical heating, than the leak detection better effects if of the leak detection of trying the water.Do not need the extra electrical heating mouth of pipe is sealed during detection, easy to detect, detection efficiency is high.And the utility model is simple in structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the circuit theory diagrams of controller of the vacuum pump of the utility model;
Among the figure: 1, sealable tank, 2, tracheae, 3, vacuum pump.
Embodiment
A kind of specific embodiment as shown in Figure 1, it comprises sealable tank 1, tracheae 2, vacuum pump 3 and controller.Tracheae 2 one ends connect sealable tank 1, and the other end of tracheae 2 connects the air entry of vacuum pump 3.Vacuum pump 3 connects the controller of control vacuum pump 3 work.
As shown in Figure 2, controller comprises transformer BK, air switch SF1, foot-switch SF2, time relay KT, relay K M1 and relay K M2.The operating circuit of the output terminal of transformer BK, the operating circuit of relay K M1, relay K M2 and the motor M of vacuum pump 3 are connected into a loop.The operating circuit series connection back of the control circuit of relay K M1 and time relay KT is parallelly connected with the control circuit three of the control circuit of relay K M2 and time relay K T; Connect with foot-switch SF2 after aforementioned three's parallel connection; And then parallelly connected, and then be connected into the loop with air switch SF1, power supply with the input end of transformer BK.Foot-switch SF2 is a normally closed switch, and time relay KT is normally closed and the relay of time closing.
Principle of work:
(1) sealable tank 1 is covered on the outside of the electrical heating mouth of pipe of installing on the electrically heated inner bag.
(2) vacuumize through 3 pairs of sealable tanks 1 of vacuum pump sealable tank 1 is adsorbed on the inner bag.
Closed power switch SF1; Step on foot-switch SF2 (foot-switch SF2 from normally closed be converted into disconnection); The control circuit outage of relay K M1 and relay K M2; The switch of relay K M1 and relay K M2 breaks off, the control circuit outage of time relay KT, the switch closure of time relay KT.
Closed power switch SF1; Unclamp foot-switch SF2; Foot-switch SF2 returns to original state, and the control circuit of relay K M1 and relay K M2 gets electric, the switch make and break of relay K M1 and relay K M2; The control circuit of time relay KT gets electric, and the switch of time relay KT trigger (setting 1 ~ 5 second) under closure state breaks off.Vacuum pump 3 work.
Time relay KT reaches delay time, and the switch of time relay KT breaks off, the outage of relay K M1 control circuit, and the switch of relay K M1 breaks off, and vacuum pump 3 quits work.
(3) inflate to inner bag.
(4) rotating liner judges through the state of sealable tank whether the electrical heating mouth of pipe leaks gas, and sealable tank falls down from inner bag and representes the gas leakage of the electrical heating mouth of pipe, and sealable tank does not fall down from inner bag and representes that the electrical heating mouth of pipe is air tight.
