Description

The tap water automatic shutoff valve

One, technical field.

The present invention relates to a kind of inlet valve that utilizes water tank overflow water to close automatically, particularly be directed against a kind of tap water automatic shutoff valve of solar water heater.

Two, background technique.

Mostly existing solar water heater is manual water inlet, manually closes water, has disclosed automatic water stopping device to be installed in the water tank, need go up the roof during installation, and goes up water tube hose and bear tap water pressure; Electronic water closing device cost is high, complicacy and inconvenient installation; This shutoff valve is a kind of simple in structure, use easy to maintenance, indoor simple and easy installation and on existing basis, installing; Needn't change former water valve; Exempt from electricity, safety, utilize recirculation water to close inlet valve automatically, thereby avoid human negligence to forget closing inlet valve and cause water resource waste and heat-energy losses.

Three, summary of the invention.

Like Fig. 1, Fig. 2, Fig. 3: be connected to new type handle (1) on the spool (11) of rotation inlet valve; New type handle (1) profile is circular; Also available other shapes (as microscler or oval) with spanner effect substitute, and new type handle in this device (1) center portion is inlayed or processed the mounting hole (2) that matches with inlet valve spool front end; The socket (3) of an outstanding or depression is established in the circumference somewhere of new type handle (1), and a protruded stigma perpendicular to its face (4) is established in a side, when new type handle (1) rotate, can drive spool (11) rotation; If a support (5), inboard are fixedly mounted on the valve base portion or are fixed on the same plane of mounted valve with screw, support arranged outside one plectrum hole (9); An if rotating spring; Claim torsion spring (6), an end is connected with support (5), and the other end is connected with protruded stigma (4) or socket (3); In support both sides and socket (3) corresponding position one plectrum (7) is set; Plectrum one end and support are inboard to flexibly connect; The other end stretches into plectrum hole (9), the support outside; Plectrum (7) can be in the space of plectrum hole (9) straight line motion, be connected a spring (8) between support and the plectrum, make plectrum insert socket (3) naturally; After water tanks such as water heater are filled water, just can overflow, the water that overflows is flowed out by flow-off (10); If a draw-off device is made up of large and small funnel, little funnel (13) is positioned in the big funnel (12); Little funnel water leakage is less than inflow, and big funnel water leakage is greater than inflow, and little funnel (13) is connected with a backguy (22) or connecting rod with plectrum (7); Big funnel is fixed on the overflow below; Spilling water directly flows to little funnel, when the water in the little funnel reaches constant weight, just spurs plectrum decline and breaks away from socket, and new type handle (1) is closed inlet valve under the effect of torsion spring automatically.

The buoyant device that aforementioned draw-off device by large and small funnel combination can change among Fig. 6 substitutes: place in the container (24) with ball float (23); This moment, socket (3) and plectrum (7) were arranged at the spool top; Container (24) places the top of water valve, and the water displacement of container (24) needs less than inflow, and backguy (22) or connecting rod are connected from the introducing of container (24) bottom and with ball float; The buoyancy of ball float drives backguy or connecting rod makes plectrum (7) break away from socket (3), realizes this function.

Aforementioned alternative by the piston apparatus among also available Fig. 7 of draw-off device of large and small funnel combination: locate to seal socket one piston sleeve (15) at overflow (10), place a piston (14) in the piston sleeve (15), one section internal diameter of the nearly overflow of piston sleeve and piston coincide; Another section internal diameter smoothly is enlarged into horn-like uncovered; Open a threading hole (16) at spill pipe elbow top, pass threading hole (16) with a backguy (22) or connecting rod and connect plectrum (7) and piston (14), after water tanks such as water heater are filled water; The water that overflows is flowed out by flow-off (10); Piston is just stressed, makes plectrum break away from socket (3) thereby drive backguy (22), realizes this function.

Because valve spool length differs; Can be like Fig. 2, Fig. 4, Fig. 5: it be hexagonal configuration that end face is further made in the hole (2) in the new type handle (1); And comply with axially along stretching out one section axle sleeve (18); Place hexagon nut (17) in the axle sleeve (18), line and spool termination coincide in the hexagon nut, and hexagon nut is screwed after can in axle sleeve, sliding into the spool termination.

For preventing that torsion spring (6) from causing damage to spool, can make a sleeve (19) at the support installation side like Fig. 7; Sleeve (19) is an integral body with support, and during installation, sleeve (19) is in axle sleeve (18) periphery; Torsion spring set is in sleeve (19) periphery, torsion spring (6) two ends respectively with support and protruded stigma effect.

The available following structure of aforementioned plectrum (7) substitutes: like Fig. 8, Fig. 9; At the support installation side one column cap (20) is set, plectrum (7) one ends are enclosed within column cap (20) upward also can be around rotation, and the other end is connected with backguy (22) or connecting rod; The gib head (21) that adapts with protruded stigma is made at the middle part; If a spring (8) two ends respectively with support and plectrum effect, the gib head (21) on the plectrum is hooked column cap, thereby can realize this function.

The invention has the beneficial effects as follows, can avoid the people to cause water resource waste and heat-energy losses for forgetting Guan Shui, indoor installation, ease of Use (needn't change former water valve), easy to maintenance, exempt from electric safety.
