Abstract
The utility model relates to a water valve, comprising a valve body. An one way main valve is horizontally arranged in the valve body and a starting device is arranged at the lower side of the one way main valve; in the meantime, a side hole is arranged on the valve wall of the lower side of the one way main valve; an air intake valve which can be opened facing the inner side of the valve body. Comparing to the current backwater valve, the utility model does not need assistant energy sources with the advantages of low cost, easy manufacturing and convenient using. The utility model can discharge the water stored in the water pipe of the water storing device which is out of the notification chamber of the solar energy water heater, solving the defect of easy frozen in winter, avoiding the mass cold water discharging process when using the water, and contributing to save water resource.
Description
Technical field
The utility model relates to the water valve field that can control automatically.
Background technique
In some water storage equipment as fields such as solar water heaters, in order to realize automatic loading water, water is completely cut off the water, and emptying in time in return pipe, existing back-water valve (BWV) is electric energy or magnetic energy control back-water valve (BWV), and its manufacturing is loaded down with trivial details, and difficulty is big, cost is higher, and the palpus supplementary energy is difficult for promoting.
Technological scheme
The purpose of this utility model is exactly the deficiency that will overcome existing back-water valve (BWV), invents the automatic backwater of a kind of energy, and need not be by the valve of electric energy or magnetic energy.
The purpose of this utility model is achieved in that automatic backwater valve, comprise valve body, the unidirectional main valve of lateral arrangement in valve body, at unidirectional main valve arranged beneath opening device, simultaneously, offer side opening on the valve body wall below the unidirectional main valve, arranging at the side opening place can be to the inboard air intake valve of opening of valve body.
Be provided with projection in unidirectional main valve bottom, described opening device comprises the cross bar of lateral arrangement on valve body wall, and cross bar the inner is butted on above-mentioned projection, the cross bar outside is nested with in spring, its outer end is provided with lever, and lever is hinged in the valve body outside, and the lever the other end connects can lead to indoor stay cord.
The utility model is simple and reasonable for structure, makes simply, and is easy to use, is applicable to as water storage boxs such as water heaters and uses, water on stopping automatically when water is full, and surplus water in the timely emptying water pipe, the utilization of raising water resources, conserve water resource.When being applied to water heater, the water swelling that the water pipe that exposes winter can not be freezed splits, and the excellent popularization using value is arranged.
Description of drawings
Accompanying drawing is the utility model structural representation
1 unidirectional main valve among the figure, 2 breather cheek valve doors, 3 ring-shaped rubber packing rings, 4 ring-like bayonet sockets, 5 pulleys, 6 springs, 7 steel wire tow lines, 8 rubber stoppers, 9 cross bars, 10 ebonite tubes, 11 levers, 12 ring washers, 13 valve bodies.
Specific embodiment
Valve body 13 of the present utility model is a circular pipe, offers the hole in a side direction of tube wall, and the inboard hinged breather cheek valve door 2 in the hole is arranged ring-shaped rubber packing ring 3 in its outside.
The unidirectional main valve 1 of lateral arrangement bottom band projection in the valve body 13 above breather cheek valve door 2, one end of this valve is hinged on annular bayonet socket 4, the bottom of the other end is butted on the T shape cross bar 9, cross bar 9 is supported in the side opening of valve body 13, the inboard that is positioned at valve body 13 is provided with ring washer 12, be positioned at cross bar 9 outer casing springs 6 in valve body 13 outsides, the outer end connects pulley 5, and rubber stopper 8 is engaged in the spring 6.
Hinged lever 11 above valve body 13, the middle part of lever 11 is butted in the groove of pulley 5, and the other end of lever 11 connects a steel wire tow line 7, and steel wire tow line 7 is applied in the ebonite tube 10 that inside is provided with spring, and ebonite tube 10 1 ends are connected valve body 13 outsides.
The utility model is installed on the outer turnover water pipe place of water tank, is vertical direction and arranges; Steel wire tow line 7 is by ebonite tube 10 parcels, and ebonite tube 10 1 ends are fixed in valve body 13 places, and the other end is fixed in the family, controls as the bicycle brake pipe.
When spring 6 was in relaxed state, water flowed from lower to upper, because the effect of hydraulic pressure, unidirectional main valve 1 is backed down, and water covers water tank, and the hole that laterally disposed breather cheek valve door 2 is withstood tube wall by hydraulic action does not leak outside.
Water is full in water tank, close water supply valve, stop to go up water inlet, unidirectional main valve 1 is subjected to the action of gravity of water in the water tank, fall after rise downwards and block passage, water can not flow backwards in the water tank, and because atmospheric effect, laterally disposed breather cheek valve door 2 is backed down, water in the valve body of unidirectional main valve below 1, in the water pipe is got rid of, this part water can be by the discharging of indoor outlet valve, realize in the pipe anhydrous, play antifreeze, once the effect of opening hot water.
When the needs water, at indoor pulling steel wire tow line 7, and fixing, lever 11 promotes cross bar 9 and backs down unidirectional main valve 1, can realize water.
Use up water, unclamp steel wire tow line 7, the power of release action on cross bar 9, spring 6 restores, and cross bar 9 is resetted, and unidirectional main valve 1 falls, and blocks passage.
Claims (6)
1, automatic backwater valve comprises valve body, it is characterized in that the unidirectional main valve of lateral arrangement in valve body, at unidirectional main valve arranged beneath opening device, simultaneously, offer side opening on the valve body wall below the unidirectional main valve, arranging at the side opening place can be to the inboard air intake valve of opening of valve body.
