Drawings
Fig. 1 shows an internal structural schematic diagram of an embodiment of the present invention.
Fig. 2 shows an external structural schematic diagram of an embodiment of the present invention.
In the figure: 1. the valve comprises a valve plate, a valve body, an opening, a large diameter portion, a small diameter portion, a rotating shaft, a swing rod, a cylinder and a torsion spring, wherein the valve plate is 2, the valve body is 3, the opening is 4, the large diameter portion is 5, the small diameter portion is 6, the rotating shaft is 7, the swing rod is 8, and the torsion spring is 9.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model relates to a bronze plate check valve, including valve plate 1 and valve body 2, the valve body is equipped with the shoulder hole, and the both ends of shoulder hole are opening 3 respectively, and the shoulder hole includes major diameter portion 4 and minor diameter portion 5, and the valve plate is installed in major diameter portion, and valve plate fixed connection axis of rotation 6, the rotation direction of axis of rotation and the place plane parallel of shoulder hole, the valve body are equipped with the through-hole, and the through-hole is passed to the axis of rotation, axis of rotation fixed connection pendulum rod 7, and the free end of hinged joint cylinder 8 is passed through to the pendulum rod, and the.
The working principle of the embodiment is as follows: the cylinder, the swing rod and the valve body form a swing guide rod mechanism, the valve body is a fixed rack, the swing rod is a crank, the cylinder is a sliding block and a guide rod, and when the free end of the cylinder moves, the swing rod can be driven to swing, so that the valve plate is controlled, and the valve plate and the stepped hole can be opened or closed.
According to the above embodiment, preferably, the rotation shaft is provided with the torsion spring 9, both ends of which abut against the valve plate and the side wall of the large diameter portion, respectively. The torsion spring can provide pressure for the valve plate, so that the valve plate can completely close the stepped hole when being subjected to certain reverse flow pressure.
The utility model has the advantages that: the cylinder, the swing rod and the valve body form a swing guide rod mechanism, the valve body is a fixed rack, the swing rod is a crank, the cylinder is a sliding block and a guide rod, and when the free end of the cylinder moves, the swing rod can be driven to swing, so that the valve plate is controlled, and the valve plate and the stepped hole can be opened or closed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
