Description

Solar diverter

One, technical field

The utility model relates to the device of diversion after a kind of solar energy water heater pipe emptying.

Two, background technology

At present, solar water heater has obtained increasing use because it has characteristics such as considerable energy saving environmental protection.

But in use especially when temperature is low, its yard piping usually causes freezing of outdoor inlet and outlet pipe lines stifled because water is arranged, and has a strong impact on the normal use of solar water heater.

The patent No. is the gas introducing-type emptying of ZL01237499.7 in the prior art, can solve the difficult problem of pipe freezeup preferably, though this purging method is reliable, need first the preceding paragraph running water come diversion during water again after the emptying, so can't use after cutting off the water; Also has the exhaust-valve that the patent No. is CN01261313.4 in addition, though the normal water of energy after cutting off the water is because water level is lower in the solar water container, when interior conduit has the U type to bend, the not empty generation gas of water row in the bend is stifled, and the water when causing water in the water tank is unable to come down.

Three, summary of the invention

The objective of the invention is defective, a kind of priming device of simple in structure, safe and convenient to use, dependable performance is provided at above-mentioned prior art.

For achieving the above object, the utility model is realized by the following technical solutions:

A kind of solar diverter comprises upper and lower conduit, and the bottom of upper and lower conduit is communicated with two interfaces by valve: cold water inlet and hot water outlet, be provided with air inlet pipe, and the tail end of described air inlet pipe is provided with stop valve, and the top is communicated with upper and lower conduit; The lower end of described upper and lower conduit is communicated with an end of the water absorber of bleeding through valve, and the other end of the water absorber of bleeding is communicated with atmosphere through valve.

Above-mentioned solar diverter, the described water absorber of bleeding comprises pump bowl, is provided with piston and piston rod in the pump bowl, and working end one end of pump bowl is communicated with upper and lower conduit through valve, and the other end is communicated with atmosphere through valve.

Above-mentioned solar diverter, described valve of bleeding between water absorber and the atmosphere is a check valve, the conducting direction of check valve for the water absorber of bleeding towards the atmosphere direction; Bleeding can be provided with check valve between water absorber and upper and lower conduit, and the conducting direction of check valve is that the upper and lower conduit direction is towards the water absorber of bleeding; Bleed between water absorber and ambient atmosphere, have at least position, a place to be provided with stop valve in the position, two places between water absorber and upper and lower conduit of bleeding; Described stop valve can be common stop valve, also can be the unidirectional shutoff valve of buoyancy, the unidirectional shutoff valve of described buoyancy comprises the crown through hole of taper or garden, the corresponding buoyancy top plug that fluctuates that is provided with through hole, the top plug is along with horizontal plane fluctuates, when the valve horizontal plane arrived certain altitude, the top plug was blocked through hole and is realized damming.

The utility model operation principle is as follows:

During last water, open the valve of cold water inlet, close all the other each valves, cold water enters water tank through upper and lower conduit, and water completely back is flowed out by overflow pipe, closes water supply valve this moment and can finish the water conservancy project work.

During emptying, open the hot water outlet valve of air inlet pipe valve and upper and lower conduit, close all the other valves, the water in the upper and lower conduit can flow out automatically, treat that current are intact after, valve-off is finished in emptying.

When needing water after the emptying, open the stop valve of bleeding between water absorber and ambient atmosphere, bleeding the position, two places between water absorber and upper and lower conduit, close all the other valves, the reciprocating sliding piston, at the effect lower pumping water absorber of check valve the air in the upper and lower conduit is extracted out and to be discharged into the external world, until water is extracted out from water tank, if common stop valve shut off valve then in this process, if the unidirectional shutoff valve of buoyancy is automatic-diversion closure then, open hot water outlet valve water then and get final product.

The utility model is compared with prior art, has the following advantages: simple in structure, emptying is effective, prior art is carried out simple refit get final product; Add water in the water pipe up and down during water, even under not having the not enough situation of cold water or hydraulic pressure, normally use the water in the solar water container.

Four, description of drawings

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

Fig. 2 is the water absorber concrete structure schematic diagram of bleeding.

Five, the specific embodiment

The following correlation technique content of not addressing all can adopt or use for reference prior art.

As shown in Figure 1, a kind of solar diverter, comprise upper and lower conduit 1, the bottom of upper and lower conduit 1 is communicated with two interfaces by stop valve 2,3 separately: cold water inlet and hot water outlet, also include air inlet pipe 4, the tail end of described air inlet pipe 4 is provided with the peak that stop valve 5, top are communicated with upper and lower conduit 1, and connectivity points is higher than the high liquid level (HLL) of water tank 6; The bottom of upper and lower conduit 1 is connected with the water absorber 7 of bleeding, its concrete structure as shown in Figure 2, it comprises drum type brake pump bowl 71, is provided with piston 72 and piston rod 73 in the pump bowl 71, piston rod 73 is externally connected with handle 74.

Upper end one end of pump bowl 71 is communicated with upper and lower conduit 1 through check valve 8, and the conducting direction of check valve 8 is that upper and lower conduit 1 direction is towards the water absorber 7 of bleeding; The other end is communicated with atmosphere through check valve 9, the conducting direction of check valve 9 for the water absorber 7 of bleeding towards the atmosphere direction.

Described bleed 1 of water absorber 7 and upper and lower conduit be provided with stop valve 10 communicating pipe; Described stop valve is for being the unidirectional shutoff valve of buoyancy, the unidirectional shutoff valve of described buoyancy comprises the crown through hole of taper or garden, the corresponding buoyancy top plug that fluctuates that is provided with through hole, the top plug is along with horizontal plane fluctuates, when the valve horizontal plane arrives certain altitude, the top plug is blocked through hole and is realized ending, and it can adopt the unidirectional shutoff valve of buoyancy of the prior art; Hot water outlet stop valve 3 is lower than the unidirectional shutoff valve of buoyancy in the pipeline, thereby the water in the unidirectional shutoff valve of buoyancy also is drained and does not influence next step use when guaranteeing emptying.

During last water, open the stop valve 2 of cold water inlet, close all the other each valves, cold water enters water tank 6 through upper and lower conduit 1, and water completely back is flowed out by overflow pipe 11, closes to close water stop valve valve 2 and get final product.

During emptying, open the stop valve 3 of air inlet pipe 4 and the hot water outlet stop valve 2 of upper and lower conduit 1, close all the other valves, the water in the upper and lower conduit 1 can flow out automatically, treat that current are intact after, valve-off is finished in emptying.

During water, close all the other valves, reciprocating sliding piston handle 74, effect lower pumping water absorber 7 at check valve extracts the air in the upper and lower conduit 1 side by side toward extraneous out, until hot water is extracted out from water tank 6, the unidirectional shutoff valve of buoyancy this moment cuts out automatically and dams, and opens hot water outlet stop valve 3 waters and gets final product.
