Specific embodiment
The embodiments of the present invention is illustrated with preferred embodiment with reference to the accompanying drawing.
It please refers to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 combine, a kind of reduced form check valve and return water system, including list
To backwater valve 1, left three-way valve 2 and right three-way valve 9, the left three-way valve 2 and the right three-way valve 9 difference
It is installed on 1 two ends of unidirectional backwater valve, the unidirectional backwater valve 1, the left three-way valve 2 and described
Right three-way valve 9 constitutes return water system 4, is equipped with elastic slice buckle 8, the elastic slice buckle 8 inside the unidirectional backwater valve 1
It is connected with 5 head end of elastic slice, the elastic slice 5 is equipped with groove 5-1, institute in the 1 water (flow) direction side of unidirectional backwater valve
The groove built-in type stated is equipped with movable block 6, and raised key 7 is equipped at the top of the movable block 6, and the raised key 7 assembles
Inside the groove 5-1, the left three-way valve 2 includes the hot water inlet 10 for being set to top, is set to bottom
Hot water outlet 11 and it is set to middle part and first water return outlet 12 interconnected of unidirectional backwater valve 1, the right side three
Port valve door 9 includes the hot water backwater mouthfuls 13 for being set to top, be set to the cooling water inlet 14 of bottom and be set to middle part with it is described
Second water return outlet 15 interconnected of unidirectional backwater valve 1,1 cross-sectional direction of unidirectional backwater valve be equipped with Y type add
Strong root 16,16 bottom of Y type enhancing root are equipped with gasket 17, and the gasket 17, which has, buffers water pressure energy power, described in raising
Unidirectional backwater valve 1 service life, the 16 top both ends of Y type enhancing root and 1 internal diameter of unidirectional backwater valve
Lap welding connects, and 16 apex angles of Y type enhancing root are 60 °, and two sides angle is 150 °, embedded by the movable block 6
It is mounted in the groove 5-1, can effectively prevent 6 backswing of movable block, to improve the compactness of cooperation；By being equipped with
Y type enhancing root 16, substantially increase the forced area of the unidirectional backwater valve 1, the movable block 6 can be effectively prevent
Impulse force is excessive and cause to cooperate imbalance that part cooperation compactness is caused to reduce when the cooperation elastic slice 5 is sprung back；When user sets
When entering water circulation model surely, cold water, which enters to be heated into from the cooling water inlet 14, is output to the hot water backwater after hot water
Mouthfuls 13, the hot water backwater mouthful 13 is defeated in the hot water inlet 10 by hot water, when user does not open water valve, hot water from
First water return outlet 12 enters the unidirectional back-water valve (BWV) 1, and hydraulic pressure opens the elastic slice 5, is recycled back to described second
Water return outlet 15, stores reuse again, so recycles repeatedly；When user is set as common hot-water mode or opens water valve, cold water
Enter to be heated into from the cooling water inlet 14 and is output to the hot water backwater mouthful 13 after hot water, the hot water backwater mouthful 13
By hot water it is defeated in the hot water inlet 10, hot water enters the unidirectional back-water valve (BWV) 1 from first water return outlet 12, will
Elastic slice 5 compresses, and after heating, hot water is flowed directly out water by hot water outlet 11, and in the unidirectional backwater valve 1 described at this time
Hydraulic pressure dynamic balance, elastic slice 5 are closed, and water can not recycle, thus, it is possible to reduce core part optimizes technique, and reduction is scrapped
Rate and cost；Meanwhile passing through the dress of the elastic slice 5, elastic slice buckle 8 and movable block 6 that are provided only in the unidirectional backwater valve 1
Match, reach the function of simple and mechanical folding, long-term work will not reduce cooperation precision because of scale formation；Further pass through
Unidirectional backwater valve 1, the left three-way valve 2 and the right three-way valve 9 constitute return water system 4, realize partial installation
Mode can be replaced paragraph by paragraph once there is damaged part, it is more economic and practical；The elastic slice 5 is flicked by hydraulic pressure, when in water
When having foreign matter, it diameter can pass through out of part cavities body, not will cause delay, it is more durable.
As shown in fig. 6, further, the movable block 6 is rounded, is designed to circle, can uniformly bear hydraulic pressure, will not
Cause to swing because hydraulic pressure is uneven, so that ensuring compactness in the unidirectional backwater valve 1.
Further, the elastic slice buckle 8, the elastic slice 5 and 6 surface of movable block are coated with antirust paint
Face prevents phenomenon of getting rusty caused by stagnating by prolonged water flow, improves its service life.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
