Abstract

The utility model provides a solar-powered water-heater watering self-closing valve, which belongs to the solar-powered water-heater watering auto-control scope. The prior watering control which adopts microcomputer has the disadvantage of high cost; the prior watering control which adopts float ball has the disadvantage of being fixed on the top of the building with the water-heater and difficulty of maintenance; the prior watering control which adopts attended mode has the disadvantage of extra labor and water overflow damage caused by inattention. The utility model comprises a watering valve and a piston-type cut-off valve; wherein, an operating handle with gear (2) is fixed on a valve spool mandrel (1) of a quick-opening straight-through watering valve; the piston-type cut-off valve comprises a cylinder body (3), a piston (4), a piston rod (5) and a cylinder body end shield (8), the cylinder body is integrated with the quick-opening straight-through watering valve, a backwater outlet (7) is arranged on the cylinder body, a backwater pipe joint (9) is arranged in the center of the cylinder body end shield (8), a rack (6) is arranged on the piston rod which is extended out of the cylinder body, the rack is meshed with the gear (21) on the operating handle with gear (2). The utility model is applicable to the solar-powered water-heater watering control and the other liquid upward transmission control.

Description

Water automatic-closing valve on the solar water heater

(1) technical field: belong to liquid flow control valve class, relate generally to water automation field on the solar water heater.

(2) background technology: the water management annex has advanced microcomputerized control and adorns upward water of float-ball type sealing valve control in the above on Gong Ying the solar water heater in the market, the most original is manually opens water supply valve and sits back and waits behind the door and keep an eye on, after treating that backwater flows out, remove to close water supply valve again.Though micro computer automatically control is advanced, once break down, general family can not repair, its cost height, and the general common people are home-use, and this is few; Water is gone up in the control of float-ball type sealing valve, though it is few to spend than microcomputerized control, because of all being contained on the roof with solar water heater, it is just very difficult that maintenance inconvenience at ordinary times, especially Old Age Homes go up roof, even be unable to handle, and also demander's help brings a lot of inconvenience; Personnel selection seeing and going up water, though save money, operate simple again, because of busy once leave away and can not in time return, water tank water completely after, full sinuous flow causes unnecessary loss or to neighbours' injury.

(3) summary of the invention:

Technical problem to be solved in the utility model is: at microcomputerized control valency height, the deficiency and the control of float-ball type sealing valve of inconvenience oneself maintenance of general family are contained in maintenance inconvenience on the roof, manually keeping an eye on water can not be from people's weak point, design a kind of low cost, need not go up the roof maintenance, do not choose and keep an eye on, just can realize the valve that the full late gate of water tank water is closed automatically.

The technical scheme that solves the problems of the technologies described above is: water automatic-closing valve on the solar water heater, it comprises water supply valve door and piston type valve-off, the higher authorities that it is characterized in that opening soon the spool core bar of through type water supply valve are fixed with band operated gear handle, the piston type shut off valve is by cylinder body, be contained in piston and piston rod in the cylinder body, cylinder end caps is formed, cylinder body with open through type water supply valve valve body soon and become one, be shaped on the backwater outlet on the cylinder body, the center of cylinder end caps is shaped on the returning pipe joint of butt joint return pipe, stretch out on the outer piston rod of cylinder body and be shaped on tooth bar, this tooth bar is meshed with gear on the band operated gear handle of opening the through type water supply valve soon.

The effect of covering of the present utility model: 1: owing to adopted the existing through type water supply valve structure of opening soon on the market, just on switch knob, add and made a gear, be meshed with the tooth bar on the piston rod of the simplest piston valve, just formed water automatic-closing valve on the solar water heater, so it is simple in structure, cost is low; 2: because this valve is contained on the indoor water supply pipeline, be convenient to overhaul at ordinary times or change, greatly facilitate the user; 3: because the butt joint of the returning pipe joint on the piston type shut off valve of this valve return pipe, only with hand is pulled band operated gear handle and just can be left away to the position of opening during last water, water tank water is full excessive when backwater is arranged, backwater just can promote piston and move, rack drives band operated gear handle 2 on the piston rod is rotated, water supply valve is closed by being opened into, and has realized closing automatically after last water tank completely, and the personnel of having saved keep an eye on water.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the defeated section of rack mesh schematic representation with piston rod of the tooth of the band operated gear handle that amplifies in the local B of Fig. 2.

(5) specific embodiment:

Employing is opened straight-through low pressure valve spool soon and is revolved the valve mechanism that turn 90 degrees the realization pass, opens, spool core bar 1 the higher authorities' handle is changed system into the operating grip 2 of band gear, the piston type shut off valve is made up of cylinder body 3, the piston 4 and piston rod 5, the cylinder end caps 8 that are contained in the cylinder body 3, cylinder body 3 with open through type water supply valve valve body soon and become one, be shaped on backwater outlet 7 on the cylinder body 3, the center of cylinder end caps 8 is shaped on the returning pipe joint 9 of butt joint return pipe.Stretch out on the outer piston rod of cylinder body 3 and be shaped on tooth bar 6, this tooth bar is meshed with gear 21 on opening through type water supply valve band operated gear handle 2 soon.When band operated gear handle 2 is consistent with last water direction, to open the through type water supply valve soon and be in the logical state of standard-sized sheet, the piston rod 5 of band tooth bar drives piston 4 and slides into cylinder end caps 8 one ends; Be in and last water direction when perpendicular at the band operated gear handle 2 of opening the through type water supply valve soon, open the through type water supply valve soon and be in full closing state, the piston rod (5) of band tooth bar drives the backwater that piston slides on cylinder body 3 and exports 7 places.

This valve is when using, and between being contained in indoor running water pipe and the solar water heater upper hose docking, the returning pipe joint 9 on this valve of the end on of solar water heater return pipe is pulled band operated gear handle 2 and made itself and last water direction consistent (shown in Figure 1).Water on the solar water heater water tank, when the full excessive inflow return pipe of water tank water, water in the return pipe is owing to the piston that has last water pressure and the vertical gravity in return pipe to promote the piston type shut off valve moves down, tooth bar 6 driven gears 21 on the piston rod 5 rotate, band operated gear handle 2 is rotated together with core bar 1, when being pushed into piston 4, backwater slides into when backwater exports 7, band operated gear handle 2 is perpendicular with last water direction, water in the shutoff, water in the return pipe flows in the basin by the outlet of the backwater on the cylinder body 37, after the water in the water heater uses up, as long as open water supply valve with hand, just can go up water, water completely back is realized closing automatically.
