Description
Technical field
The utility model relates to a kind of water supply valve that is used for solar water heater.
Background technique
At present, solar water heater, energy-saving effect easy to use because of it obviously uses very universal.For ease of daylighting, solar water heater all is installed on the roof usually, indoorly links to each other with water-heater water tank by upper and lower water pipe.Because last water need be controlled at in-house operation, therefore, how in time closing water supply valve after last water is finished becomes the problem that the user comparatively is concerned about.Be equipped with on the water-heater water tank that has and pass to indoor return pipe, when promptly treating to expire on the water-heater water tank, return pipe has water to overflow, and reminds the user to close water supply valve, and its advantage is simple in structure, cost is low, its shortcoming is: for various reasons, people usually can not in time close water valve, cause in " water overflow Kingsoft ", not only make troubles and lose, also caused a large amount of wastes of water resources simultaneously to the user.The water heater that also has installs little water tank additional on water tank, install on the little water tank float valve carry out on water management, but there is following problem in this structure: the one, and solar energy come-up ball valve and water inlet all will bear the pressure of tap water itself, break down easily, and objective environment makes very inconvenience of maintenance; The 2nd, this installation cost higher and be unfavorable for the insulation; The 3rd, want when use water heater winter earlier inlet valve to be closed, otherwise use colder and colder.The water heater that also has adopts automatic controllers such as hydraulic pressure sensor and solenoid valve, but this installation cost is very high, and maintenance is extremely inconvenient.
Summary of the invention
In order to solve the problem that water on the above-mentioned solar water heater exists, the utility model provide a kind of simple in structure, cost is low, the solarenergy water heater self-colsing liebert that can close automatically behind the solar water heater water tank filling up water.
The self-closing water supply valve of a kind of solar energy of the utility model is achieved by following technical proposals, it comprises valve body, spool and valve rod, valve body is provided with water intake and water outlet, valve handle activity is connected on the valve body, and spool is fixed in the valve pocket by valve rod, it is characterized in that valve body one side is provided with hydraulic pressure installation, hydraulic pressure installation is made up of piston and the oil hydraulic cylinder that cooperates with piston, piston is fixed on the valve rod, realizes the interlock of piston and spool, and oil hydraulic cylinder is provided with liquid entering hole.
When adopting the utility model, the utility model is installed on the intake pipe of solar water heater commonly used.The regular solar water heater is that water tank and heat collecting pipe are fixed on the roof by support, is connected with water inlet and outlet pipe on water tank, and it also comprises a three-way diverter valve, and three interfaces of this valve are connected with shower head, running water pipe and water inlet respectively.Running water pipe is connected on the water intake of the present utility model, and interface of water outlet and three-way diverter valve links to each other, and the return pipe of solar water heater is connected with the liquid entering hole of hydraulic pressure installation.During last water, three-way diverter valve by solar energy commonly used is closed the interface that leads to shower head, connect two interfaces in addition, realize that the solar energy water inlet is communicated with the water outlet of the self-closing water supply valve of solar energy, with hand propulsion piston or valve rod, piston or valve rod promote to move on the spool, and water intake and water outlet are communicated with, water in the realization.When expiring on the solar water heater water tank, water just enters oil hydraulic cylinder from the return pipe overflow by liquid entering hole, continuous adding along with water, pressure in the oil hydraulic cylinder also increases thereupon, promoting piston when reaching certain pressure moves down, therefore piston drives spool with the valve rod interlock and moves down, and realizes closing of water intake and water outlet gradually, thereby reaches the purpose that water supply valve is closed automatically.Water in the oil hydraulic cylinder is slowly oozed out by the gap of piston and oil hydraulic cylinder after water supply valve is closed gradually, realizes self-closing restore funcitons for going up water once more.
For making solar energy when having a bath, can freely control the solar water heater water-exit temperature, spool is divided into movable spool and the fixed spool that laminates mutually, movable spool and valve rod are connected, fixed spool circumferentially is fixed in the valve pocket and with valve rod and is rotationally connected, be respectively equipped with the water inlet that communicates on movable spool and the fixed spool, movable spool and fixed spool are closed by the rotary shifted water inlet that makes.When using solar energy to have a bath like this, rotation valve rod, movable spool rotates together with valve rod, fixed spool does not rotate, through hole contact ratio size on movable spool, the fixed spool is the size of may command cool water quantity, and can reach the temperature that makes solar energy spill the mixing water of shower head outflow with this can freely control.
For making the water discharge in the oil hydraulic cylinder more smooth, on oil hydraulic cylinder, also be provided with spilled water hole.When water was full of oil hydraulic cylinder, as long as stop to go up water, just very fast can the releasing from spilled water hole of water in the oil hydraulic cylinder, water supply valve can be resumed work soon again like this.
Can freely control for spilled water hole is sluiced, on spilled water hole, be provided with the controlling device of regulating the spilled water hole size.So more can freely control the time that sluices.
Because the pressure that the utility model utilizes the overflow of return pipe to produce is closed water valve, water tank can cut out water supply valve after piling water automatically, need not manually to close water valve, and simple in structure, and easy break-down is not easy to maintenance, low cost of manufacture.
