Abstract
An overfall automatic shut off water valve mated with a solar water heater, is designed for preventing the excess overfall in sucking water course of the solar water heater. A switch wheel [3] is fixed on the switch shaft [2] of a water valve main body [1]. Crown trough of the switch wheel [3] is connected with a soft pulling rope [4] which is connected to a hanger [5]. The hanger [5] hangs a hanging beam [6] which has a soft pulling rope [7] between two ends. Lower part of the soft pulling rope [7] is connected with a small-bore container [8], an overfall water inlet tube [9] inserted in the container [8]. When water overflowed from the water tank flushes into the small-bore container [8] via the overfall water inlet tube [9], three downward forces are produced to the small-bore container [8], wherefore the small-bore container [8] moves downward and drives the switch wheel [3] running to realize the goal of shutting off the water valve.
Description
The utility model relates to a kind of water valve that has spilling water automatic closing device that is used to prevent the excessive spilling water of solar water heater.
Present most solar water heaters are all just closed water supply valve and are intercepted water when seeing that overflow pipe begins there are flowing out.Sometimes people have been because forgotten the observation spilling water, fail in time to close valve, and water is excessively overflowed, and have caused great waste.Therefore, people have taked to utilize spilling water to close water supply valve automatically and have finished the measure that intercepts water.As patent 94244105.2 self-closing water-supply valve of solar water heater, water automatic controller and patent 01222789.7 solar water heater water-supply apparatus on patent 99203789.1 solar water heaters.These devices all are that the water that has utilized overflow to get off makes deactivation secondary mechanics mechanism of mechanics mechanism one time as power, remove to close valve by secondary mechanics mechanism again, therefore, all are the overall structure more complicated; The part material variation is as necessary flexible material, flexible material, corrosion resistant material; Requirement on machining accuracy is higher, as the manufacturing of guiding valve, action component; Part material requires high, as needs be cast iron, copper material, stainless steel material, otherwise can be very short in the following life-span of action of rust of water.Therefore there are manufacture cost height, the problem that maintenance expenses is high naturally.
The purpose of this utility model is exactly to overcome above-mentioned deficiency with very simple device, and can reach and utilize the water overflow to close water supply valve automatically to realize the purpose that intercepts water.
The technical solution adopted in the utility model is that the switch axle [2] on water valve main body [1] is gone up installation switch wheel [3], in all grooves of the wheel of switch wheel [3], be connected with soft drawn rope [4], soft drawn rope [4] is connected with hook [5], hang with hanging beam [6] on the hook [5], the two ends of hanging beam [6] are connected with soft drawn rope [7], soft drawn rope [7] lower end connects a small-caliber vessel [8], is inserted with overflow water inlet tube [9] in the small-caliber vessel [8], and overflow water inlet tube [9] is inserted into container bottom.When the water that overflows from water tank pours small-caliber vessel [8] by overflow water inlet tube [9], small-caliber vessel [8] is produced 3 kinds of following downward active forces: 1) the downward impact force of water; 2),, produce downward opposition so flow velocity is accelerated when flowing out small-caliber vessel [8] on the current direction because the formed slit of inlet tube [9] of the bore place of small-caliber vessel [8] and overflow water is very little; 3) gravity of water.Therefore, small-caliber vessel [8] moves down, and drives switch wheel [3] and rotates, and realizes closing the water valve purpose.The material of switch wheel [3], hook [5], hanging beam [6], small-caliber vessel [8] and overflow water inlet tube [9] can be a metal, also can be nonmetal, as plastics etc.The diameter range of switch wheel [3] is 30 to 300 millimeters, and the wheel week of switch wheel [3] also can right and wrong are complete takes turns week.The bore place diameter range of small-caliber vessel [8] is 10 to 30 millimeters, and the diameter range of the position that container is thick is 10 to 300 millimeters, and altitude range is 30 to 500 millimeters.Soft drawn rope [4] and soft drawn rope [7] can be metal or nonmetal chain, also can be cord.
The utility model is that valve is directly closed in a mechanics mechanism.Therefore, inevitable structure is easier, and material is not had specific (special) requirements, and the relative prior art products of cost is extremely low, and maintenance cost is extremely low, longer service life.
Fig. 1 is the schematic representation of spilling water automatic closing water valve.
Among the figure, [1] is the water valve main body, and [2] are switch axles, and [3] are switch wheels, and [4] are the soft drawn ropes, and [5] are hooks, and [6] are hanging beams, and [7] are the soft drawn ropes, and [8] are small-caliber vessels, and [9] are the overflow water inlet tubes.
Most preferred embodiment of the present utility model is as follows:
As shown in Figure 1, promptly the switch axle [2] on water valve main body [1] is gone up switch wheel [3] is installed, in all grooves of the wheel of switch wheel [3], be connected with soft drawn rope [4], soft drawn rope [4] is connected with hook [5], hang with hanging beam [6] on the hook [5], the two ends of hanging beam [6] are connected with soft drawn rope [7], and soft drawn rope [7] lower end connects a small-caliber vessel [8], be inserted with overflow water inlet tube [9] in the small-caliber vessel [8], overflow water inlet tube [9] is inserted into container bottom.The material of switch wheel [3], hanging beam [6 ,] small-caliber vessel [8] and overflow water inlet tube [9] is plastics.The diameter of switch wheel [3] is 100 millimeters, takes turns week for complete; The bore place diameter of small-caliber vessel [8] is 18 millimeters, and the diameter of the position that container is thick is 60 millimeters, highly is 100 millimeters.Soft drawn rope [4] and soft drawn rope [7] are the metallic aluminium chains.
