Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make more clear and definite definitions of the scope of the present invention.
The utility model relates to an integrated double-circuit ball check valve, as shown in figure 1 combines figure 2, including valve body 1 and ball 2, valve body 1 is the symmetrical structure setting, and structural layout is reasonable. The ball 2 is made of rubber or rubber coated, so that abrasion caused by rigid collision is avoided.
Wherein, two water inlets 3 of valve body 1 lower part inwards upwards collect the delivery port 5 on upper portion through a fluid passage 4 respectively, delivery port 5 is located two water inlets 3 directly over the centre, gathers same delivery port 5 play water at two inside water inlets 3 of valve body 1, can follow two water inlets 3 and intake simultaneously, also can follow any water inlet 3 and intake alone.
And a water inlet sealing ring 6 is arranged at each position of the water inlet 3, and the water inlet sealing ring 6 is a rubber part, so that rigid collision is avoided, and the use sealing performance is ensured. The valve body 1 is provided with the orbit that a ball passageway 7 is used for placing ball 2 or control ball 2 respectively at arbitrary water inlet 3 homonymy, and ball passageway 7 upwards arranges outwards from water inlet 3, and arbitrary fluid passage 4 has formed a connector 8 with the ball passageway 7 of homonymy, the diameter of ball 2 is greater than the diameter of water inlet 3 and the diameter of connector 8, restriction ball 2's moving range. When the check valve is in a non-working state, the ball 2 is tightly pressed on the two water inlet sealing rings 6, and the backflow of the fluid above the ball 2 is effectively prevented. When water enters from the water inlet 3 under pressure, the round ball 2 is jacked up in the round ball channel 7, the pressure water enters the water outlet 5 through the flow channel which is reserved by the water inlet 3 through the round ball 2, and when the water enters from the water inlet 3, the round ball 2 falls to the initial position along the round ball channel 7 under the action of gravity and is in close contact with the water inlet sealing ring 6, so that the backflow of fluid is prevented.
Any the other end of the round ball channel 7 is provided with an outward horizontal opening access hole 9, a flange is arranged at the position of any access hole 9 so as to facilitate connection, and the diameter of the round ball 2 is smaller than that of the access hole 9, so that the round ball 2 can be put into and taken out from the access hole 9. The maintenance port 9 is correspondingly provided with a sealing cover 10, the maintenance port 9 and the sealing cover 10 are sealed by an O-shaped sealing ring 11 and sequentially threaded with a screw 12 and a flat gasket 13 to be locked by a nut 14, when the water stop valve needs to be maintained, the check valve does not need to be detached from a pipeline, only the screw 12 and the nut 14 on the sealing cover 10 need to be loosened, the sealing cover 10 is opened, each flow passage in the valve body 1 can be cleaned, the ball 2 is checked or replaced, after the cleaning, the checking or the replacement is completed, the O-shaped sealing ring 11 is placed, the sealing cover 10 is covered, the screw 12 and the flat gasket 13 are sequentially threaded, and the nut 14 is locked.
The valve body 1 is respectively provided with two symmetrically inclined release grooves 15 between any access hole 9 and the water outlet 5 in a communicated manner, the width of each release groove 15 is smaller than the diameter of the ball 2, the falling of the ball 2 is avoided, and the release grooves 15 are used for the circulation of fluid in the valve body 1 so that the fluid can press the ball 2 down after the ball 2 is jacked up.
The utility model relates to an integrated double-circuit ball check valve, the utility model discloses simple structure, reasonable integrated overall arrangement double-circuit tee bend non return scheme has effectively reduced the cost, has reduced occupation space, through setting up the access hole separately and set up sealed lid respectively, and it is convenient to overhaul, effectively reduces intensity of labour, improves maintenance efficiency.
The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without changing or replacing the technical scope of the present invention disclosed by the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
