Abstract

The utility model provides a solar electric pipeline emptying valve. In the structure of the emptying valve, an upper valve body is screwed in a lower valve body shell, a seal ring with a central holeis arranged at the center of the upper end of the upper valve body, the upper end of the seal ring is provided with a plug, a connecting rod is fixed on the lower end of the plug, a piston is fixed on the lower end of the connecting rod, and is inserted in a sleeve, the upper end of the sleeve is screwed in the upper valve body, and the sleeve is surrounded by an electromagnetic coil, which is covered by a coil shell; a spring is arranged between the center of the lower end of the piston and the sleeve; and a heat-preserving layer is arranged between the lower valve body shell and the coil shell. Compared with the prior art, the utility model can feed water at any time no matter the power is on or off, and during operation, the utility model can normally operate without pressure difference; because the bottom of the emptying valve is provided with a bottom water tube, the water in the emptying valve can be totally emptyed, and thereby the outdoor emptying valve cannot be frozen and blocked in winter.

Description

The solar energy electric pipe line evacuation valve

1, technical field

Specifically a kind of solar energy electric pipe line evacuation valve of the utility model.

2, background technique

The solar energy exhaust-valve can effectively carry out switch control to the water in the water tank, realizes that one opens instant-heating and outlet hot, and winter, pipeline did not freeze stifled, still not enough below the existing solar energy exhaust-valve ubiquity:

(1), existing exhaust-valve needs certain pressure difference and just can open normally, close; Even the zero pressure exhaust-valve also costs an arm and a leg because of it and shortcomings such as water flow is little can not be used widely by the user;

(2), suitable suction tude is not set in the exhaust-valve, can't be with the whole emptyings of the water in the exhaust-valve, freeze stifled phenomenon winter easily;

(3), electromagnetic coil can not normally effectively be closed under the situation of vertically state use for being horizontally disposed with in the existing exhaust-valve, causes exhaust-valve to be not closed completely easily, pipeline occurs and freeze stifled phenomenon;

(4), existing exhaust-valve structure is comparatively complicated, rate of fault height, and working life is shorter, so the marketing difficulty is big.

3, summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and cost is lower, the water in solar water container and the pipeline is realized the solar energy electric pipe line evacuation valve of good control.

The technical solution of the utility model realizes in the following manner, its structure middle and upper part valve body and lower body shell are by being threaded, the upper end of upper body is fixed with suction tude, the central position, upper end of upper body is provided with the seal ring of band center hole, the upper end of seal ring is provided with stopper, the lower end of stopper is fixed with connecting rod, the lower end of connecting rod is fixed as piston, the outer installment of piston is a sleeve, the upper end of sleeve and upper body are by being threaded, the sleeve outer installment has electromagnetic coil, and the outer installment of electromagnetic coil has coil case; Be provided with spring between the central position of piston lower end and the sleeve; The lower body shell is provided with thermal insulation layer with coil case and sleeve parcel between lower body shell and coil case.

The upper and lower opening of above-mentioned sleeve communicates, and the sleeve lower end is connected with the bottom water pipe, and the bottom water pipe passes the lower body shell.

Above-mentioned upper body is set to circular, and suction tude contacts with the inner chamber of upper body and communicates.

Above-mentioned piston is set to cylindric, and the piston upper end has the mouth of a river up and down.

Above-mentioned ring inner hole communicates with the bottom water pipe.

When using on this exhaust-valve water, need not energising, water can directly enter valve body by the bottom water pipe, enter solar water container through valve body and suction tude again, when last intact water, power switch is opened, again solar energy is mixed water valve and forward only sunny state that can water to and get final product; In the time of water, powered-down switch, magnetic force disappear, and stopper rises under the effect of lower end spring force, and the water in the water tank enters user terminal water place by the ring inner hole exhaust-valve of flowing through.

The utility model has the advantages that:

Solar energy electric pipe line evacuation valve of the present utility model is compared with prior art, has reasonable in designly, easy to use, and need not during work provides pressure difference to get final product proper functioning; The bottom of this device is provided with the bottom water pipe, the whole emptyings of the water in the exhaust-valve effectively can be avoided winter occurring freezing stifled phenomenon in outdoor exhaust-valve.
