Abstract
The utility model discloses an automatic pipeline emptying valve for a solar water heater. Structural key points are that an emptying water faucet with an air inlet hole is arranged on an upper water pipe; an air inlet pipe is connected to the air inlet hole; an emptying valve is connected to one end of the upper water pipe. One end of the emptying valve is connected to a water pipe at the bottom part of a water tank. An air breaking gap is formed in the middle of a pipeline in the emptying valve. One end of the air inlet pipe is connected to the emptying valve. A steam-water separation valve is arranged in the connection position between the emptying valve and the air inlet pipe. The utility model thoroughly solves the problem of easy freezing due to the mixing of the air inlet pipe of a past emptying valve. The utility model has the advantages of convenient operation, easy control, simple structure, low cost, and strong applicability.
Description
The utility model relates to a kind of defroster of solar water heater, relates to the automatic exhaust-valve of a kind of pipelines of solar water heater specifically.
Because solar water heater is easy to use, save the energy, do not have any pollution, and use safe and reliable, so be widely used.But colder at north of china in winter, the outdoor pipeline of solar water heater freezes easily, and improper use can cause the damage of water heater.For solving this class problem, main method has thickening pipeline heat-insulation layer, or twines method such as heat tape on pipeline, and all can not thoroughly solve the pipeline frozen problem with these methods, and use inconvenience, the cost height, the life-span is low.Also have at present and use emptier, but most of emptier complicated operation, poor stability, the easy backwater of air inlet pipe, so still can freeze, can not solve winter solar completely can antifreeze problem, user's coefficient safe in utilization is little.
It is simple and convenient that the purpose of this utility model is to provide a kind of use to install, and resistance to frost is good, and is easy and simple to handle, and cost is low, the automatic exhaust-valve of safe and practical pipelines of solar water heater.
The purpose of this utility model is achieved in that
One emptying water nozzle is installed on upper hose, on the said emptying water nozzle air admission hole is arranged, connect an air inlet pipe on this air admission hole, the other end at said upper hose connects exhaust-valve, the other end of this exhaust-valve connects the water pipe of water tank bottom, in the middle of the pipeline gas breaking joint crack is arranged in the said exhaust-valve, the other end of said air inlet pipe connects exhaust-valve, in the junction of said exhaust-valve and said air inlet pipe the carbonated drink seperating vale is installed.During last water, open water supply valve, water sprays under the effect of exhaust-valve reducing, enters water tank by gas breaking joint crack; When needing emptying, open the emptying water nozzle, automatically draining is air-breathing, and atmosphere, makes the water emptying of pipeline and can not intake in the air inlet pipe in gas breaking joint crack by the gas-water separation valve action; During water, pipeline is recovered to water state by siphonage.
Advantage of the present utility model is:
Because the gas-water separation valve has been installed, make water can not enter air intake duct, thoroughly solved the difficult problem of exhaust-valve, air intake duct mixing easy freezing in the past, allow the four seasons use hot water to come true; The utility model adopts the emptying water nozzle, uses simple and conveniently, grasps easily, need move emptying water nozzle spanner, and emptying can be finished automatically; The utility model is simple in structure, and cost is low, and adaptability is strong, can be installed on any solar water heater, can save a large amount of insulation material of anti-freezing pipeline, reduces installation cost, for installation and maintenance bring convenience.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, one water supply valve door 2 is arranged on the upper hose 1, one emptying water nozzle 3 is installed on the upper hose on the water supply valve door, air admission hole 4 is arranged on the emptying water nozzle, connect an air inlet pipe 5 on this air admission hole, at the other end connection exhaust-valve 8 of said upper hose, the other end of this exhaust-valve connects the water pipe of water tank bottom, in the middle of the pipeline gas breaking joint crack 7 is arranged in the said exhaust-valve, the other end of said air inlet pipe connects exhaust-valve, in the junction of exhaust-valve and air inlet pipe carbonated drink seperating vale 6 is installed.
Claims (1)
1, the automatic exhaust-valve of a kind of pipelines of solar water heater, it is characterized in that: upper hose (1) is gone up an emptying water nozzle (3) is installed, air admission hole (4) is arranged on this emptying water nozzle, connect an air inlet pipe (5) on this air admission hole, the other end at said upper hose connects exhaust-valve (8), the other end of this exhaust-valve connects the water pipe of water tank bottom, gas breaking joint crack (7) is arranged in the middle of the pipeline in the said exhaust-valve, the said exhaust-valve of another termination of said air inlet pipe is installed carbonated drink seperating vale (6) in the junction of exhaust-valve and air inlet pipe.
