Abstract

The utility model provides a lifting orifice type empty valve for a solar energy pipeline, which is not afraid of scales and impurities. When in winter, especially the cold of boreal climate can enable pipelines to suffer frost crack, and the solar energy pipeline can not be used. A rubber pipe is arranged on an inserting hole of a rubber pipe of the empty valve and inserted in the inlet of a solar energy refrigerator. A pipe orifice lifting control device is arranged in the rubber pipe, users can use water in a solar energy water tank by lowering the pipe orifice into the water, equivalently opening a valve port. When draining water, users can lift the pipe orifice above a water surface, the water in the pipe does not flow after being drained, and a pull-and-push rod is controlled by a motor. The empty valve is characterized by a spring arranged on the pull-and-push flexible cable of the pull-and-push rod, when the pull-and-push rod moves upwards, the spring resets, the rubber pipe becomes a vertical shape, the pipe orifice is separated from the water surface and in an emptied state, the spring is pulled through the flexible cable when the push-and-pull rod moves backwards, the pipe orifice of the rubber pipe falls into the water, thereby entering a water-using state. The empty valve has the advantages of being simple in installation, convenient to use, long in service life, low in cost and the like.

Description

A kind of lifting mouth of pipe formula solar tube emptying valve

Affiliated technical field

The utility model relates to a kind of solar energy exhaust-valve, especially a kind of lifting mouth of pipe formula solar tube emptying valve.

Background technique

The solar water heater majority is mounted in the roof, water pipe is connected to indoor, no matter be that last water or water pipe interior have water all the time, especially boreal climate is cold in the time of winter can produce the bursting by freezing pipe phenomenon, cause and to use, so just there are a lot of producers to research and produce exhaust-valve several years ago, thinking is very simple, sealing solar water container mouth, the water of pipeline is ejected, not only frozen pipe not can go out hot water once opening on the contrary, but majority is a way of utilizing sealing solar energy intake-outlets such as electric ball valve, plunger valve.Its key reason is that water quality is mostly bad, there are problems such as impurity scaling, cause the bad sealing phenomenon, exhaust-valve is malfunctioning, rate of fault is very high, because exhaust-valve is longer standby time, 1 year most time need not, more cause a large amount of impurity incrustation scales on valve port, to winter the more basic startup of time spent motor do not get up or cause the gear-box fragmentation, even if start up also is that most valve port bad sealings leak, and this phenomenon is ubiquitous, and quality can not get ensureing at all, its main cause exhaust-valve is to use winter, the valve port sealing requires very strict, must be watertight, so adopt the mode of sealing valve port to be difficult to meet the requirements.

Summary of the invention

Purpose of the present invention just provides a kind of lifting mouth of pipe formula solar tube emptying valve of not being afraid of incrustation scale impurity.

Above-mentioned purpose is realized by following technological scheme, there is a sebific duct to replace valve on this exhaust-valve sebific duct socket, be inserted in solar water container and import and export the inside, the sebific duct the inside is provided with lifting mouth of pipe control gear, in the entry of during water the mouth of pipe being landed, suitable and valve port is opened, just can use the water of solar water container the inside, during emptying mouth of pipe rise has been higher than the water surface, the current in the pipe are intact just no longer to have flowed, quite with the valve sealing, avoided original ball valve, plunger valve etc. the problem of existence.

Control lifting mouth of pipe scheme is as described below.

The scheme 1 of the said control lifting mouth of pipe: this exhaust-valve sebific duct socket outside is inserted with the sebific duct control gear in the sebific duct the inside, and the Electric Machine Control pull bar with being provided with telescopic shaft is characterized in that; In sebific duct, telescopic shaft links to each other with pull bar, and pull bar links to each other with soft rope, and soft rope links to each other with spring, spring on the pull bar push-pull cable, soft Suo the higher authorities are connected one side of spring, so during the pulling spring, Point of Strength is not or not the center, and spring is just crooked on one side, and sebific duct just moves with spring naturally.When pull bar moves upward, soft rope loses pulling force to spring, spring reset, sebific duct the vertical-type shape, it is emptying state that the mouth of pipe has left the water surface, when pull bar moves backward by soft rope pulling spring, spring is to a lateral bending song, sebific duct is bent downwardly design angle 90 degree with spring, and the sebific duct mouth of pipe promptly falls into the water, at this moment for using water state.

The scheme 2 of the said control lifting mouth of pipe: this exhaust-valve sebific duct socket outside is inserted with sebific duct, control gear is not inner at pipe, the motor that employing is provided with telescopic shaft is the dynamic Control pull bar, and its feature links to each other with pull bar at telescopic shaft, and pull bar and lifting linking member be hinge mutually, pull bar drives lifting linking member work, individual ring set is arranged on the lifting bar on sebific duct, when pull bar moved backward, lifting linking member upwards promoted water pipe by the collar, when the mouth of pipe leaves the water surface, be emptying state.When telescopic shaft moved upward, pull bar promoted lifting linking member, and the higher authorities of lifting linking member move downward, and the collar and sebific duct land in water, for using water state.

The scheme 3 of the said control lifting mouth of pipe: this exhaust-valve water seal is identical with scheme 1 with the structure on top.With the bottom is to utilize two valve bodies to press from both sides a film, and the edge plays seal action, is provided with stage clip between film and the following valve body, has individual space to be made as gas bag between film and the upper valve body, leaves inflation inlet, is to utilize air to do power.Be characterised in that; The pull bar lower end is passed water seal and is linked to each other with film, the pull bar upper end links to each other with soft rope, soft rope links to each other with spring, pull bar links to each other with film, film is provided with stage clip on one side, be provided with gas bag on one side, the pull bar lower end is passed water seal and is fixed on the film center, and the pull bar upper end connects soft rope, the soft rope spring that links to each other, spring pushes away pull bar forward when static, and soft rope loses pulling force to spring, the spring self-return, sebific duct leaves the water surface by spring force, be emptying state, when utilizing air that the gas bag film is pressurizeed, film drives pull bar and moves down, because there is soft rope to be connected on one side of spring on the pull bar, the spring nature is crooked on one side, and water pipe is also just fallen into the mouth of pipe in the water with spring is crooked simultaneously, at this moment for using water state.If gas bag and spring are fallen a upper/lower positions mutually, gas bag at following stage clip on top, its working method just in time can be turned around so, exhaust-valve just can use by side.

Its beneficial effect is; Replace complicated valve, avoided fault, can improve solar energy utilization rate greatly.Have and install simply, easy to use, the life-span is long, low cost and other advantages.
