Abstract
Pressure type vacuum tube solar water heater, attemperater is installed on the stent of the water heater, attemperater both sides are separately installed with water inlet pipe and outlet pipe, lower part is provided with vacuum tube, pressure-limiting exhaust valve is installed at the top of attemperater, metal tube is set with vacuum pipe inner cavity, metal tube upper end opening, it is sealingly mounted on the wall of inner container of attemperater, connected with the inner cavity of attemperater, metal tube lower end seals, vacuum tube upper end is inserted into the insulating layer in the shell of attemperater, mouth of pipe outer wall retainer plate, it is fixed on tank shell, metal tube lower end is set with fixing card, fixing card is supported on vacuum inside pipe wall.The junction sealing welding of metal tube and condenser hot well liner has connecting tube, and thread seal connects between connecting tube and metal tube.Since the hydraulic pressure that metal tube can be born is larger, whole hydraulic pressure in water supply pipe are born, vacuum tube is not contacted with water, and therefore, the pressure that the utility model can be born is larger, and frost resistance is stronger.
Description
Technical field
This technology belongs to technical field of solar water heaters, is related to a kind of pressure type vacuum tube solar water heater.
Background technology
Many solar water heaters are all using vacuum tube as heat collecting element, with the heat vacuum tube of vacuum tube absorption
Cold water in inner cavity, the cold water water temperature rise being heated in pipe, density reduce, and hot water moves upwards, and under heavy cold water
Tube bottom is dropped to, continues to heat, it is ensured that hot water is constantly flowed into water tank from bottom to top.Since vacuum tube is double-layer glass structure, its
Anti-pressure ability is smaller, and this vacuum tube frost resistance is poor, it is impossible to is directly connected with outer water supply pipe, is not suitable for working as water tank and water outlet
House of the difference in height within 10 meters uses.
The content of the invention
The purpose of this utility model is to provide a kind of pressure type vacuum tube solar water heater, solves in the prior art, very
Blank pipe solar water heater bears the problem of pressure is small.
The technical solution of the utility model is：A kind of pressure type vacuum tube solar water heater, on the stent of the water heater
Attemperater is installed, attemperater both sides are separately installed with water inlet pipe and outlet pipe, and lower part is provided with vacuum tube, in insulation water
Pressure-limiting exhaust valve is installed, vacuum tube outer wall suitable for reading is inserted into the insulating layer in the shell of attemperater, the mouth of pipe at the top of case
Outer wall is fixed on tank shell with retainer plate, and metal tube is set with vacuum pipe inner cavity, and metal tube upper end opening lower end is close
Envelope, the outer wall of openend are sealingly mounted on the wall of inner container of attemperater, are connected with the inner cavity of attemperater, end cap under metal tube
Fixing card is filled, fixing card is supported on vacuum inside pipe wall.
The junction sealing welding of metal tube and condenser hot well liner has connecting tube, and connecting tube lower end is machined with internal thread,
Metal tube upper end is machined with external screw thread, and thread seal connects between metal tube upper end and connecting tube.
Using the technical solution of the utility model, metal tube is co-axially mounted in vacuum tube, the upper end of metal tube is installed on
On the liner of attemperater, bottom after vacuum tube absorbs heat, is heated the cold water in metal tube by end cap seal,
Hot water in metal tube after heating rises, and flows into water tank, cold water, which then drops in metal tube, to be continued to heat.Since metal tube can be held
The hydraulic pressure received is larger, bears whole hydraulic pressure in water supply pipe, and vacuum tube is not contacted with water, and therefore, the utility model can be held
The pressure received is larger, and frost resistance is stronger.
