The water circuit is described herein in terms of the water inlet and outlet circulation pattern set forth in the present invention. Hot water enters the water inlet pipeline 314 through the water inlet pipe 110 and the water inlet-connecting heating pipe 102, then enters the lower closed cavity 407 through the water inlet-connecting heating pipe joint 402, and because the water inlet-connecting heating pipe joint 402 and the water outlet-connecting heating pipe joint 404 are communicated with the lower closed cavity 407, water enters the water outlet pipeline 312 through the water outlet-connecting heating pipe joint 404, then enters the water outlet-connecting heating pipe 104 and finally is discharged through the water outlet pipe 107.
By the oil passage and the water passage structure, it can be seen that the oil flow process needs to pass through the outside of the water passage, so that the oil is heated by the hot water when passing through the pipe gap oil passage formed between the left sleeve 305 and the water inlet pipe 314 and between the right sleeve 301 and the water outlet pipe 312.
The invention combines the advantages of several generations of heaters, and makes up for the advantages of the following:
1. the principle that the oil way wraps the high-temperature waterway is adopted.
2. The whole section bar is used for replacing an independent pipeline, so that the stability is enhanced.
3. And (3) encapsulating and protecting to integrate the multiple joint points and the surface.
4. A single exhaust protection valve is newly added to prevent inverted oil leakage and internal overpressure.
5. And the heating effect of the aluminum profile is improved.
6. And the integrity of the section is utilized, a plurality of connection points and surfaces are removed, and only the upper surface and the lower surface are used.
7. The sealing is changed from a plane single rubber cushion into six sealing (two rubber rings, one convex-concave groove, one plane, one embedded rubber and one rubber filling).
8. The glue filling has no dead angle, and the heater is integrated.
The invention comprises a heater head main body 1, a heater head lower shell 2, a heater tube group 3 (a middle aluminum profile integral pipeline) and a heater lower connecting assembly 4 (a heater lower shell); the heater top dustproof and waterproof cover (detain on sensor socket box 111, form a sealed cavity with sensor socket box 111, place some connecting wire etc.), heater head main part 1, heater head lower casing 2 constitute whole heater top casing to heater head lower casing 2 is complete to overlap in heater nest of tubes 3 upper end, and corresponding plug in on heater head main part 1 corresponding position, can add some marks such as trade mark, model at heater top dustproof and waterproof cover.
The four connectors of water inlet, water return, oil inlet and oil return of the heater head main body 1 are in a quick-insertion mode, two layers of sealing rubber rings are additionally arranged, independent work is not interfered with each other, and the situation that people are mixed is avoided.
1. The joint inside the water pipe and the oil pipe is a plug connector.
2. The plug connector is sealed to be a double-layer O-shaped sealing ring (nitrile rubber).
3. And (5) sealing with a flat gasket.
4. And (5) sealing by epoxy resin glue.
5. Exhaust check valve (intake and exhaust port 112): the inner part of the air inlet and outlet 112 is divided into a narrow area 1122 and a wide area 1124, a steel ball 1121 for sealing is arranged in the wide area 1124, the outer diameter of the steel ball 1121 is smaller than that of the wide area 1124 but larger than that of the narrow area 1122, the steel ball 1121 is arranged on a cross ventilation bottom bracket 1123 at the bottom of the wide area 1124, the cross ventilation bottom bracket 1123 is a middle cross bracket, the steel ball is prevented from falling, and other parts can facilitate the air flow. When the heater is turned over, the steel ball falls into the cone portion (narrow-area inlet), so that the sealing effect is achieved.
The lower shell of the heater is an aluminum profile combined fastener and is partially and integrally molded with the profile, and after the lower shell is sleeved on the heater tube group 3, a groove area is formed in the periphery of the heater tube group 3 and used for filling epoxy resin in the groove area to seal and protect stability.
The lower seal is made of a 45-degree nitrile rubber material, the oil resistance, the high temperature resistance, the ageing resistance and the chemical resistance of the material are good, the material is inserted into a gap in the section bar, the sealing contact area is increased, then the glue filling and the section bar of the plastic part form a secondary package, and the seal is more reliable.
The heater nest of tubes 3 is integrated into one piece, and the upper end is pegged graft with heater head main part 1, and the lower extreme forms oil, the independent subregion return circuit of water respectively with heater head lower casing 2 to when oil passed through the oil return circuit, because oil circuit itself just cladding is peripheral at the water route, so under the water route pipe wall heat conduction form, carries out the omnidirectional heating with oil.
Summarizing: the pipeline connection points are reduced, leakage points are relatively reduced, and the upper connection point is moved upwards to the outer side of the oil tank, so that hidden danger of leakage is reduced. After the section bars are combined into a whole, the whole stress of each pipeline is mutually supported, and the firmness is increased. The plastic part and the section are injected into a whole, so that the connecting structure is changed, and the hidden trouble of leakage is eliminated. The exhaust seepage prevention technology is added, the water-in-oil design is improved, multiple seals are mainly added, the rubber cushion is changed from a plane into a three-dimensional embedded plane seal, and after filling and sealing, only two sealing surfaces and a plastic part are integrated, so that a leakage channel is eliminated, a heater is integrated, no leakage point exists, and the heater is safer and more reliable.
