Abstract
The invention discloses a multifunctional emptying and overflow solenoid valve of a special solar pipe. The product is mainly used for solving the problem that the solar pipe is subject to frost crack in winter. The solenoid valve is used normally in summer and is automatically turned on for emptying the pipe when the temperature is below zero in winter; the solenoid valve helps mainly reduce solar mounting materials and save one drain pipe; a water supply valve is turned off, an emptying valve is turned on and a drain valve is turned on when water overflows, thus discharging excess water overflowing in a water tank, and the discharged water can be reutilized; and the solenoid valve saves water and electricity and has stable performance. An injection molding material and a self-holding electromagnet are adopted in a valve body, and the solenoid valve is freely turned on and off. The valve body is interconnected with an overflow port of the water tank; a control system is mainly connected with the valve body, a water temperature sensor, a dual-water level sensor (dual fail-safe and high safety coefficient), a temperature sensor, a water supply solenoid valve, a water tank emptying solenoid valve and a drain solenoid valve to a control instrument to perform operation; and the solenoid valve has simple and convenient use, and helps reduce manual operation.
Description
Technical field
The present invention presses self-holding electromagnetic valve for the nothing that solar water heater uses.By realizing that solar water heater uses the residual water in the automatic emptying pipe to be used to prevent frost crack pipe winter.
Background technique
At present, when solar water heater uses winter, for preventing that the residual water bursting by freezing pipeline in the yard piping from having dual mode, many a kind of employing pipelines twine heating tape heating outward, and using winter is to heat in 24 hours, and voltage is 220 volts, power consumption is big, when simultaneously heating tape service time is long or quality when not passing a test, how can produce the accident of fire and electric leakage, potential safety hazard is big.Another kind is the pipe evacuation mode, promptly utilizes solenoid valve that the water of pipeline is drained.This method is used solenoid valve more, and the solenoid valve that is now using mostly is and adds a plunger sealing in pipeline, can reduce the area of caliber so again, also can influence the flow of water, and hydraulic pressure is not enough when causing bathing, the drawback that can't use.
Summary of the invention
For overcoming the deficiency that the solenoid valve that is now using reduces flow, the invention provides a kind of solenoid valve, can not influence the flow of water, can finish the function of emptying, can realize water if be furnished with water level upper limit relief cock, a pipeline is used in emptying and overflow, reduces installation cost.Power is little, and power consumption is low, and voltage is 12 volts of direct current safety voltages.Guaranteed Security.
The present invention for the scheme that the technical solution problem adopts is: the cylinder type valve body is a nylon, is furnished with the self-locking electromagnet, the leak-stopping plunger, water intake has screw thread to be connected with solar water container, the following mouth of a river has screw thread to be connected with pipeline, the plunger sealing is the mouth of a river down, and relief opening communicates with pipeline and is connected with the solar water container overflow hole.When under the needs during water electromagnet inhale and back outage self-sustaining open mode, because spatial area can not reduce the flow of water in the cavity greater than the 4 internal diameter areas of being in charge of, the mouth of a river under plunger sealing during emptying, current end, because relief opening is connected with the solar water container overflow hole, promptly communicate, when emptying system forms passage when drain valve is opened within doors with the external world, residual water in the pipeline is discharged, reach the purpose of pipe evacuation.When solenoid valve can be finished the function of water on the water tank during for opening state, cistern water level reaches in limited time, relief cock action (promptly providing a signal identical) with emptying, close the tap water water supply valve, closed electromagnetic valve, following drain valve is opened, unnecessary water is gone into pipeline by an exhaust orifice flow that is connected with the solar water container overflow hole and is discharged, overflow effect when realizing dilutional hyponatremia on the water tank, water and overflow are a pipeline realizations in, an overflow pipe that need add during minimizing installation solar water heater.
Beneficial effect of the present invention is, opening Shi Buhui influences the flow of water and realized last water, emptying, and a pipeline is used in overflow, has reduced the cost of installing.Be furnished with thermal switch control, quartzy joint quick and easy for installationly can not slipped up, and voltage is low, and the little power consumption of power is few, and outage can self-sustaining advantage.
Description of drawings
Further specify below in conjunction with accompanying drawing:
Fig. 1 state when sectional drawing emptying and overflow when the closed condition;
When Fig. 2 is bathing for the sectional drawing of open mode and the state during last water;
Fig. 3 is a scheme of installation
Among the figure: 1. water intake; 2. valve body; 3. self-sustaining electromagnet; 4. thermal switch; 5. quartzy connector assembly; 6 springs; 7. have the elastomer diaphragm plunger; 8. the relief opening that is connected with the water tank overflow hole; 9. descend osculum; 10. solar water container; 11. overflow hole; 12. outlet pipe; 13. the utility model solenoid valve; 14. pipeline; 15. last water solenoid valve; 16. pipe drainage solenoid valve; 17. bathing shower nozzle valve.
Embodiment
Last water solenoid valve 15 is closed condition when not going up water.
During emptying: 3 releases of self-sustaining electromagnet have elastomer diaphragm plunger 7 and seal down osculum 9, make water inlet saliva 1 sealing that is connected with solar water container, pipe drainage solenoid valve 16 is opened, be connected outlet pipe 12 with the water tank overflow hole, relief opening 8. pipelines 14 and pipe drainage solenoid valve 16 form passage discharges the residual water in the pipeline.
During overflow: also be this step of repetition; 16 times of opening of pipe drainage solenoid valve can be set at 10 minutes and can close, but the just emptying of the water of pipeline.
During bathing: after providing signal, self-sustaining electromagnet 3 is inhaled and is had 7 outages of elastomer diaphragm plunger and keeps, and fetches boiling water with following osculum 9 and pipeline 14 bathing shower nozzle valves and flows to into the shower nozzle bathing but open water intake 1;
On the water tank during water: self-sustaining electromagnet 3 is inhaled and is had 7 outages of elastomer diaphragm plunger and keeps, and opens water intake 1 and the following osculum 9 upward water of realization that communicates with water solenoid valve 15 on the pipeline 14.
