Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a double-plate check valve body for reducing pressure loss comprises a valve body 1, a rotating shaft 2, a fixed shaft 3 and a torsion spring 4 are arranged in the valve body 1, the rotating shaft 2 and the fixed shaft 3 are both fixed on the valve body 1, the torsion spring 4 is provided with two pieces and sleeved on the rotating shaft 2, the rotating shaft 2 is rotatably connected with two connecting pieces 5, the two connecting pieces 5 are respectively positioned on two sides of the rotating shaft 2 and fixedly connected with a valve clack 6, the fixed shaft 3 is connected with the valve clack 6 through the torsion spring 4, two sides of the valve clack 6 are respectively provided with a water inlet cavity 7 and a water outlet cavity 8, one side of the valve clack 6 close to the water inlet cavity 8 is of an.
Two torque arms of the torsion spring 4 are respectively and fixedly connected with the fixed shaft 3 and the valve clack 6, and the two torque arms of the torsion spring 4 are positioned between the fixed shaft 3 and the valve clack 6 fixedly connected with the fixed shaft.
And then ensure that valve clack 6 has certain elastic recovery, when rivers assault valve clack 6 from intake antrum 7, valve clack 6 will rotate certain angle, and when no rivers 'effect, valve clack 6 will realize recovering original position under torsion spring 4's effect.
The rotating shaft 2, the valve clack 6, the fixing shaft 3 and the torsion spring 4 are all positioned in the water outlet cavity 8, and the valve clack 6, the rotating shaft 2 and the fixing shaft 3 are distributed from near to far away from the water inlet cavity 7.
And then avoid rivers in the intake antrum 7 and the continuous contact collision of structures such as pivot 2 and lose a large amount of kinetic energy for the condition such as self loss of pressure is great takes place.
A cross beam 13 is arranged between the two valve clacks 6, one end of the cross beam 13 close to the water outlet cavity 8 is of an arc surface structure, energy loss to water flow when the cross beam 13 is in contact with the water flow is further reduced, and a sealing piece 9 matched with the valve clacks 6 is arranged on the cross beam 13.
