Abstract
A kind of anhydrous pressure testing device of enamel inner container, including enamel inner container, the top of the enamel inner container side is provided with return pipe, and bottom is provided with water inlet pipe, and the import of the return pipe connects air inlet pipe with loose joint, alarm is connected above the air inlet pipe, highly sensitive pressure gauge is provided with above the alarm, the centre of the air inlet pipe is provided with check valve, and the inlet end of the air inlet pipe is provided with to be connect soon, fast and easy accesses compressed air, and relief valve is connected on the water inlet pipe.Beneficial effect：The present apparatus without manual wipping, saves time and the cost of labor of water drying, pressure alarm is reminded plus manual confirmation, ensures the accuracy that product judges, improves product qualification rate without inner bag is soaked in into the problem of avoiding getting rusty in water.
Description
Technical field
The utility model belongs to technical field of solar water heaters.
Background technology
Enamel inner container is the core component of solar water heater, to ensure the welding quality of inner bag, it is necessary to be beaten one by one
Pressure leak detection, current leak hunting method is fairly simple, and punching inside enamel inner container is filled into certain compressed air during leak detection, then will in
Courage is totally immersed among pond, has bubble to occur being considered as unqualified, but this method exists in use：1st, staving
Got rusty easily after entering water, 2, must be time-consuming by water stain wiped clean before foaming, 3, slight seepage easily judge by accident,
Easily cause product quality problem.
The content of the invention
The purpose of this utility model is to be directed to the deficiency present on, there is provided a kind of precision is high, leak detection is quick, avoids getting rusty
The anhydrous pressure testing device of enamel inner container.
The technical solution adopted in the utility model：A kind of anhydrous pressure testing device of enamel inner container, including enamel inner container, it is described to ward off
The top of porcelain inner bag side is provided with return pipe, and bottom is provided with water inlet pipe, and the import of the return pipe connects air inlet pipe, institute with loose joint
State and alarm is connected above air inlet pipe, highly sensitive pressure gauge is provided with above the alarm, the centre of the air inlet pipe is set
There is check valve, the inlet end of the air inlet pipe is provided with to be connect soon, fast and easy access compressed air, and pressure release is connected on the water inlet pipe
Valve.
Utility model works principle；, will by the check valve among air inlet pipe by compressed air when enamel inner container is hunted leak
Inner bag closes check valve after being pressurized to the pressure value specified, and siren will be sent out after the reading of pressure gauge drops to default value
Go out alarm song, that is, there are leakage problems, after the dwell time is reached, it is qualified that observation pressure gauge numerical value is considered as in setting range, inspection
Drain junction beam, the relief valve release operating pressure on water inlet pipe is opened, completes a workflow.
The utility model beneficial effect：The present apparatus by inner bag without being soaked in the problem of avoiding getting rusty in water, without artificial
Wipe, save time and the cost of labor of water drying, pressure alarm is reminded plus manual confirmation, ensures that product judges accurate
Property, improve product qualification rate.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Accompanying drawing 1 is the utility model structure diagram.
In accompanying drawing 1：1st, enamel inner container, 2, loose joint, 3, highly sensitive pressure gauge, 4, alarm, 5, check valve, 6, connect soon, 7,
Air inlet pipe, 8, return pipe, 9, water inlet pipe, 10, relief valve.
Embodiment
A kind of anhydrous pressure testing device of enamel inner container as shown in drawings, including enamel inner container 1, the side of enamel inner container 1
Top be provided with return pipe 8, bottom is provided with water inlet pipe 9, and the import of the return pipe 8 connects air inlet pipe 7 with loose joint 2, it is described enter
Alarm 4 is connected above tracheae 7, is provided with highly sensitive pressure gauge 3 above the alarm 4, the centre of the air inlet pipe 7 is set
There is check valve 5, the inlet end of the air inlet pipe 7 is provided with connects 6 soon, and fast and easy accesses compressed air, is connected on the water inlet pipe 9
Relief valve 10.
The present embodiment by inner bag 1 by the check valve 5 among air inlet pipe 7 by compressed air in use, be pressurized to what is specified
Check valve 5 is closed after pressure value, siren 4 will send alarm after the reading of highly sensitive pressure gauge 3 drops to default value
Sound, that is, there are leakage problems, the highly sensitive numerical value of pressure gauge 3 is observed after the dwell time is reached and is considered as qualified, inspection in setting range
Drain junction beam, the relief valve 10 opened on water inlet pipe 9 discharge operating pressure, complete a workflow.
