The utility model relates to a water feeding cutoff valve for a solar water heater. The water feeding cutoff valve comprises a water feeding valve, wherein the water feeding valve is provided with a valve body, a valve core and a valve rod; the valve body is provided with a water inlet interface and a water feeding interface; the valve rod of the water feeding valve is provided with a water interception mechanism; the water interception mechanism is provided with a shell which is connected with the valve body of the water feeding valve and provided with a water outlet; an impeller is arranged in the shell; a water return interface for impacting the impeller is arranged on the shell opposite to the impeller; a central shaft of the impeller is provided with a cam; the end part of the valve rod of the water feeding valve is provided with a roller matched with the cam; a handle connected with the central shaft is arranged outside the shell; and a return spring is sleeved on the valve rod. When a water tank of the solar water heater is full of water, the cam is driven to rotate by the impeller in the return water impact water interception mechanism and the valve rod closes the water feeding valve under the action of the return spring. The water feeding cutoff valve has the advantages of simple structure, low cost, convenient installation and use, no need of making great change on the solar water heater or requiring installation personnel to climb onto a roof for installing and capability of ensuring the safety of the personnel.
Description
Technical field
The utility model relates to a kind of stop valve, water stop valve on particularly a kind of solar water heater.
Background technology
Solar energy is with its environmental protection and economy and more and more used, and solar water heater is one of them.But the last water problems of solar water heater is perplexing people always.At present, have about 50% left and right sides solar water heater not have the automatic loading water function on the market, the shared ratio of particularly early stage product is more.When the solar water heater filling up water, as can not in time closing, what that hot water will gurgle gutters down, the waste water source, even more serious is, forget close after, waste be not the water of any least bit, water spills also can be mashed the floor bubble.Product at old-fashioned automatic loading water in solar water heater is not too many in the market, installing also is special complexity, and relate to the water tank of solar water heater, aspect such as electric, this has just limited the transformation and the large-area popularization of old-fashioned solar water heater.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of simple in structure, and cost is low, water stop valve on the solar water heater easy to install.
Technical problem to be solved in the utility model is to realize by following technical scheme, water stop valve on a kind of solar water heater, comprise water supply valve, water supply valve is provided with valve body, spool, valve rod, described valve body is provided with into water interface and last water interface, be characterized in: on the valve rod of water supply valve, be provided with the mechanism that intercepts water, the described mechanism that intercepts water is provided with the housing of the band discharge outlet that is connected with the valve body of water supply valve, be provided with impeller in the housing, housing facing to impeller is provided with the backwater interface that impacts impeller, on the central shaft of impeller cam is housed, valve rod end at water supply valve is provided with the roller that matches with cam, outside housing, be provided with the handle that links to each other with central shaft, be set with back-moving spring on the valve rod.
Technical problem to be solved in the utility model can also further realize by following technical scheme, intercept water and be tightly connected by connector between the valve body of the housing of mechanism and water supply valve, described connector is provided with the cavity that matches with back-moving spring, is provided with the spring preload piece that is slidingly matched with above-mentioned cavity on valve rod.
Technical problem to be solved in the utility model can also further realize that water supply valve body cavity and spool cooperation place are quincunx inner chamber by following technical scheme.
The utility model when solar water heater water tank water is full, impacts intercept water in-house impeller by backwater owing on the valve rod of water supply valve the mechanism that intercepts water is housed, and drives the cam rotation, and valve rod is closed water valve in effect ShiShimonoseki of back-moving spring, and last water ends.Compared with prior art, it is simple in structure, does not have electrical structure; Cost is low; Easy to install, do not need solar water heater is carried out big change, do not need installation personnel to climb to the roof yet and install, guarantee personnel's safety.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Water stop valve on a kind of solar water heater, comprise water supply valve, water supply valve is provided with valve body 12, spool 13, valve rod 11, described valve body 12 is provided with into water interface 1 and last water interface 2, water supply valve valve body 12 inner chambers and spool 13 cooperation places are quincunx inner chamber, on the valve rod 11 of water supply valve, be provided with the mechanism that intercepts water, the described mechanism that intercepts water is provided with the housing 4 of the band discharge outlet 6 that is connected with the valve body 12 of water supply valve, be provided with impeller 7 in the housing 4, housing 4 facing to impeller 7 is provided with the backwater interface 5 that impacts impeller 7, cam 7 is housed on the central shaft of impeller 7, valve rod 11 ends at water supply valve are provided with the roller 8 that matches with cam 7, outside housing 4, be provided with the handle 15 that links to each other with central shaft, be set with back-moving spring 10 on the valve rod 11.Intercept water and be tightly connected by connector 3 between the valve body 12 of the housing 4 of mechanism and water supply valve, described connector 3 is provided with the cavity that matches with back-moving spring 10, on valve rod 11, be provided with the spring preload piece 9 that is slidingly matched with above-mentioned cavity, by adjusting spring preload piece 9, the elastic force size that can regulate back-moving spring 10.
During enforcement, connect pipeline earlier, the water inlet interface 1 of water supply valve connects running water, and last water interface 2 links to each other with the inlet pipeline of solar water heater, and the mechanism's backwater interface 5 that intercepts water links to each other with the water return pipeline of solar water heater, and the mechanism's drainage interface 6 that intercepts water is connected with sewer.After pipeline connects when solar water heater need be gone up water, clockwise rotate 15 one-tenth 90 ° on handle, the cam 7 coaxial with handle 15 also rotates thereupon, when cam 7 forwards maximum position to, the roller 8 that matches with cam 7 will promote the valve rod 11 of water supply valve, spring preload piece 9 is also followed back-moving spring 10 and is slided left in connector 3 cavitys, the back-moving spring 10 of suit is compressed on the valve rod 11 of water supply valve, the spool 13 of the water supply valve on the valve rod 11 of water supply valve is moved to the left to maximum position simultaneously, at this moment cavity gap maximum in quincunx, valve is opened, and running water is by water on the last water interface of blossom type cavity gap process.
