The utility model relates to solar water heater, relates in particular to a kind of control device that can make the surplus water of noresidue in the solar energy water heater pipe.

Background technology

Be reduced to when subzero at temperature, user's great majority of domestic solar water heater are to take the mode of the surplus water of emptying to protect solar water heater not to be damaged by frost.Present domestic solar water heater is that water pipe is freezing than the fault that is easier to occur, some producer takes auxilliary heat of electricity or the empty device of magnetic valve control to solve the problem that water pipe is endured cold when design, but the cost of these two kinds of water heaters is higher, and the installation and maintenance trouble costs an arm and a leg.Even in temperature higher season, people are when using solar energy, and the pipe inner cold water also is not suitable for having a bath, and wastes often.Surplus water in huge numbers of families waste this pipe, what accumulate is a googol amount.

Summary of the invention

The utility model provides at the bottom of a kind of cost at above defective, reliability height, the novel solar water heater of nothing left water in the mode of employing air pressure closed upper end delivery port realizes managing.

The technical solution of the utility model is: it comprises valve body, jockey, valve body is provided with the side opening that is communicated with mesopore, side opening connects a staving A, be provided with disk in the staving A, the disk below is provided with spring, and the disk top is connected with bar, bar is provided with rubber tube, another interior circle of establishing the staving B of mesopore connects the cylindrical of above-mentioned staving A, and bar passes the end face of staving B, and the end face of bar is provided with plate.

The axis normal of side opening is in the axis of mesopore.

In the mesopore of valve body inlet end, be provided with the sebific duct of a top closure, this pipe cylindrical is established the step circle of a diameter less than body, is provided with the groove that parallels to the axis on the tube wall of this step circle.

Described jockey comprises contiguous block and tube connector, the two ends of contiguous block are provided with stepped hole, two stepped holes are communicated with by an aperture, the stepped hole of the port of export is connected with above-mentioned valve body, the stepped hole bottom surface of entrance point is the plane, screw thread is established in the aperture, in the stepped hole of inlet end, be connected with tube connector, the mesopore of tube connector is a blind hole, establishes the straight hole of an axis normal in the tubular axis line at the tube wall of the tube connector port of export, and this straight hole is communicated with above-mentioned blind hole, establish the external screw thread that is connected with the aperture internal thread on the tube connector, tube connector port of export end face is the plane, establishes sealing ring between the circle in the cylindrical of the tube connector port of export and the contiguous block entrance point stepped hole, and the entrance point of tube connector connects aerating device.

The utility model is separated pipeline in the mode of use side face closure with extraneous, keep the interior gas pressure of pipeline greater than ambient pressure, thereby realizes the sealing to water route, pipeline upper end.When needs use in the solar energy hot water, gently press the gas bar, the elastic tube upper and lower end face with separated by dish end face and lid inner face, pipeline is communicated with by the mesopore that wears bar with extraneous, seals the air bag answer normality of delivery port water pipe, outlet pipeline connection, water outlet.At the bottom of the utility model cost, effective, have very high energy saving.
