Description
Technical field the utility model belongs to technical field of solar utilization technique, relates to a kind of solar water heater underneath type exhaust-valve.
Background technology solar water heater, water-supply pipeline evacuation are effectively to avoid the icing bursting by freezing in upper and lower conduit road to damage, and influence the effective way that solar water heater uses.In the prior art, the method for solar water heater water-supply pipeline evacuation mainly contains following several:
(1) utilize siphon principle to carry out emptying.The method of this emptying, the one, need 2-4 valve to be installed on solar water heater top and ground, connect with sufficiently long pipeline between the valve; Two when being to use sometimes the marquis put not water outlet, the water of releasing sometimes is too many, also can put the water in the exhaust-valve only unstable properties sometimes.
(2) adopt exhaust-valve to carry out emptying.The method of this emptying normally is installed in exhaust-valve the delivery port place of solar water heater emptying valve outside, connects with a metal tube.This purging method, though can be with the tube emptying below the exhaust-valve, the pipeline above the exhaust-valve but can not emptying, still can occur blocked and problem bursting by freezing.Drop to five degrees below zero when following at temperature in addition, valve body can be low excessively because of temperature, rotates difficulty, and cause the motor band not moving valve rotate and burnt out.
(3) electronic exhaust-valve carries out emptying.This exhaust-valve uses the 220V power supply, uses through transformation again, in case electric leakage, outage are all made troubles and potential safety hazard to the user, and is easy to stuckly, and the life-span is short, cost is high, inconvenient maintenance, and most disposable use is used and just scrapped in about 1 year.
The summary of the invention the purpose of this utility model be solve prior art exist water-supply pipeline evacuation not thoroughly, poor safety performance, service life is short and cost is high technical problem, provide a kind of solar water heater underneath type exhaust-valve, in order to effectively to overcome the above-mentioned drawback of existing in prior technology.
The utility model solar water heater underneath type exhaust-valve, it comprises valve body, and an end of valve body is provided with the water inlet pipe and water outlet pipe joint, and the other end is provided with connecting tube; It is characterized in that valve body is provided with air admission hole, be provided with valve rod in the valve body, valve rod is provided with spring; One end of valve rod is connected with valve block in being arranged on water inlet pipe and water outlet pipe joint chamber, the backguy pipe on the other end passes connecting tube and is arranged on connecting tube by backguy be arranged on indoor manual switch and be connected; The water-in and water-out mouth of pipe on the described water inlet pipe and water outlet pipe joint be arranged in parallel, and effluent pipe mouth is positioned at the inboard of water inlet pipe mouth; Water inlet pipe mouth is communicated with the position with water inlet pipe and water outlet pipe joint inner chamber and is provided with the mouth of a gorge, and the size at the mouth of a gorge is corresponding with the described valve block that is arranged on the valve rod.
During installation, exhaust-valve can be arranged in the below or its heat-insulation layer of solar water heater, the intake-outlet of water inlet pipe mouth on the water inlet pipe and water outlet pipe joint and solar water heater bottom is connected, with the effluent pipe mouth on the water inlet pipe and water outlet pipe joint be arranged on indoor upper and lower conduit road and be connected, with backguy be arranged on indoor manual switch and be connected and get final product.
The utility model solar energy exhaust-valve is to utilize theory of mechanics, with the water emptying in the solar water heater upper and lower conduit road, opens, and hot water is come; Close, i.e. upper and lower conduit road sky.Need not power supply, safe and reliable, simplicity of design, easy to use, sturdy and durable, service free.Be used in the height building, hand switch is located at indoor, and a complete set of equipment cost is low, installs simply, and ordinary people all can be installed voluntarily.During last water, pull back backguy, the valve block on the valve rod is positioned at the connecting portion of valve body and water inlet pipe and water outlet pipe joint, the water-in and water-out mouth of pipe conducting on the water inlet pipe and water outlet pipe joint, can be on solar water heater water; Behind the filling up water, promote backguy forward, the valve block on the valve rod is positioned at the position, the mouth of a gorge in water inlet pipe and water outlet pipe joint chamber, is about to effluent pipe mouth and stops up, at this moment, the air admission hole of air on valve body enters the effluent pipe mouth on the water inlet pipe and water outlet pipe joint in the valve and will remain in water emptying in the upper and lower conduit road.When using hot water, pull back backguy, the valve block on the valve rod is positioned at the connecting portion of valve body and water inlet pipe and water outlet pipe joint, the water-in and water-out mouth of pipe conducting on the water inlet pipe and water outlet pipe joint, i.e. available water; Not the time spent, promote backguy forward, the valve block on the valve rod is positioned at the position, the mouth of a gorge in water inlet pipe and water outlet pipe joint chamber, is about to effluent pipe mouth and stops up, and the water in the upper and lower conduit road also flows out under the effect of air in valve simultaneously.
The utility model modern design, rational in infrastructure, install simple, easy to use, water inlet pipe and water outlet pipe joint and whole upper and lower conduit road can be emptied completely, thoroughly solve and avoided solar water heater upper and lower conduit in winter road to freeze stifled and bursting by freezing, influence the normal problem of using of solar water heater.
