Description

A kind of upper and lower water combination brake switch and proporting

The utility model relates to a kind of water pipe line combination brake switch and proporting.

Prior solar water heater exists following problem, and 1, the water heater that uses of the method for falling into water, residual water can't emptying in the pipeline, exists pipeline to freeze winter at cold area, the problem that can't normally use.2, the water heater that uses of top water law though the water in the pipeline can emptying, requires the water tank must pressure-bearing, adopts this method simultaneously, also exists hot and cold water to mix, and influences the problem of using effect.3, in order to solve the problem of freezing pipeline, some water heater is provided with electric heater, but its construction is complicated, also exists the danger of electric shock, and just in case has a power failure the same hidden danger of freezing pipeline that exists.

At the problems referred to above, the purpose of this utility model provides a kind of solar water heater and some other indoor heating systems of making, and can realize the pipeline emptying, and the upper and lower water combination brake switch and proporting of water water level on can volitional check.

To achieve these goals, the utility model is taked following design: a kind of upper and lower water combination brake switch and proporting, it is characterized in that: it comprises an action valve body, described valve body center has a dividing plate that has the water inlet, corresponding with the position of described dividing plate, on described valve body, have one group of water inlet and an osculum; A upper spring cushion, it is placed on the described dividing plate; A bonnet, its top has water outlet, and described bonnet is pushed down described upper spring cushion, is fixed on described valve body top; A valve rod, its top is connected with described upper spring cushion; A lower spring cushion, its bottom that props up described valve rod is placed on the bottom of described valve body; A bottom flange, its bottom has water intake, and described bottom flange is pushed down described lower spring cushion, is fixed on described valve body bottom; A water inlet and outlet valve body, its top have a cover ball-cock assembly, and described water inlet and outlet valve body and described action valve body connect as one.

The utility model is owing to take above design, and it has the following advantages: 1, therefore the utility model can promote valve rod by the last water pressure of tap water owing to be provided with spring mattress saddle and movable valve rod up and down, opens the water inlet, to system supply hot water.This Purely mechanical structure, stable performance is not had a power failure by power supply and troubles, and uses reliably, and the life-span is long.2, the utility model is owing to be provided with the ball-cock assembly of similar water closet at the top of water inlet and outlet valve body, therefore can be after the water tank fills with water automatic shutoff, realize the control of automatic loading water water level.3, the utility model is not gone up water pressure because when not going up water, and valve rod blocks the water intake on the dividing plate by spring mattress saddle, can be except that water tank with the water emptying in the pipe-line system, thus guaranteed that the use in winter can not freeze the problem of pipeline.When 4, the utility model uses hot water, be that tap water is communicated with water intake on the lower end cap, the water flowing of jack-up valve rod, and water tank is to work under normal pressure, has therefore reduced the requirement to the water tank material.5, therefore the mixed phenomenon of hot and cold water does not take place because when water intaking, cold water only props up stem bottom, does not enter water tank in the utility model, has guaranteed 100% hot water of taking away in the water tank.The utility model can be widely used in various solar water heaters and some other indoor inlet and outlet system.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1 is the utility model structural representation

Fig. 2 is the utility model operating valve body structure schematic representation

As shown in Figure 1 and Figure 2, the utility model comprises two valve bodies, an action valve body 10 and a water inlet and outlet valve body 80.The top and the bottom of action valve body 10 have one section internal thread 11,12 respectively, have a dividing plate 13 at the center on valve body 10 tops, have a water inlet 14 on the dividing plate 13.Corresponding with the position of dividing plate 13, on valve body 10 valve walls, evenly have 3-4 water inlet 15, have an osculum 16 at the middle part of valve body 10.Place the upper spring cushion 20 of a slice plastic cement or other material on the dividing plate 13 at valve body 10 centers, the center of upper spring cushion 20 has a through hole 21.The valve rod of falling the T-shape 30, the top of valve rod 30 have a tapped hole 31.Pass the through hole 21 of upper spring cushion 20 with a screw 32, valve rod 30 is fixed on the upper spring cushion 20.A bonnet 40 is screwed in the internal thread 11 at valve body 10 tops, bonnet 40 centers have a water outlet 41.Put into a lower spring cushion 50 in the bottom of valve body 10, a bottom flange 60 is screwed in the internal thread 12 of valve body 10 bottoms, have a water intake 61 on the bottom flange 60.On the osculum 16 at valve body 10 middle parts, fix a transverse connecting pipe 70 by screw thread, the other end at connecting tube 70 is fixed water inlet and outlet valve body 80 of the present utility model by screw thread, the float valve 90 of similar water closet in the prior art is set, in order to the last water water level of control water tank at the top of water inlet and outlet valve body 80.

When installing, the utility model is installed in the water storage box of solar water heater, the water intake on the bottom flange 60 61 is communicated with intake pipe in the system, the bottom of water inlet and outlet valve body 80 is communicated with intake pipe and bathing shower nozzle in the system.When using, open running water pipe, water enters action valve body 10 from the water intake 61 of bottom flange 60, the pressure of the water overhead-valve bar 30 that makes progress, because upper and lower spring mattress saddle the 20, the 50th, flexible, it does not limit moving up and down of valve rod 30.Like this, after valve rod 30 moves up, the water that is positioned at valve body 10 tops is discharged from the water outlet at bonnet 40 tops, water inlet 14 on the dividing plate 13 is opened, water enters water inlet 14 on the dividing plate 13 by the water inlet 15 on the valve body 10 valve walls, and the 16 inflow transverse connecting pipes 70 of the osculum on valve body 10 valve walls, it is after 80s to enter the water inlet and outlet valve body, flows out from the bathing shower nozzle.

In the foregoing description, the shape of valve rod 30 also can be an inversed taper platform shape, and itself and upper spring cushion ways of connecting also can adopt rivet or other structural type.The structure of upper and lower valve gap 40,60 and also can change with the means of fixation of action valve body 10.The Placement of transverse connecting pipe 70 two ends and valve body 10 and water inlet and outlet valve body 80 can be taked welding or alternate manner, water inlet and outlet valve body 80 can not connect by transverse connecting pipe 70 yet in addition, and directly be close together with action valve body 10, make two chambeies of a valve body.In order to satisfy the needs on preparation process or the utilization structure, the utility model can also carry out some other improvement, such as, the structure shape of the dividing plate 13 at action valve body 10 centers, water inlet 15 on the valve body 10 valve walls and osculum 16 the position is set, can change to some extent as required.The main operating principle of the utility model is to open running water pipe to be equivalent to relay and to click, and hot water just flows out, and unclamps and shuts.According to this principle, can will utilize water pressure pushing valve rod 30 to change machinery control roof pressure valve rod etc. into.
