Detailed Description

The embodiments of the invention are described in detail below, but the invention can be implemented in many different ways, which are defined and covered by the claims.

Please refer to fig. 1 to 4, according to the embodiment of the present invention, the valve seat assembly of the diaphragm type check valve includes a seat body 1 and a magnet 2, the seat body 1 is provided with a mounting groove 3 and a stop step 4, the magnet 2 is disposed in the mounting groove 3, and the stop is disposed on the stop step 4, the mounting groove 3 extends to the stop step 4 from the opening of the seat body 1, the opening of the seat body 1 is provided with a riveting wall 5, the riveting wall 5 extends from the opening side end face of the seat body 1 to the direction far away from the mounting groove 3, the riveting wall 5 forms riveting fixation for the magnet 2, the diaphragm support and the seat body are fixedly connected to form an integrated valve seat assembly.

The utility model discloses a diaphragm formula check valve directly sets up on seat body opening side's terminal surface and rivets pressure wall 5, utilizes and rivets pressure wall 5 and carry out the riveting to magnet 2 fixed, need not additionally set up and carry out spacing locating part to magnet 2, consequently can reduce the installation procedure, simplifies processing technology, reduces part quantity, reduces part cost.

The riveting wall 5 is arranged on the inner peripheral side of the end face of the opening side of the base body 1, and the riveting wall 5 can be arranged at a position close to the magnet 2, so that the riveting fixation of the magnet 2 can be ensured by making the height of the riveting wall 5 smaller, the root of the riveting wall 5 can be utilized to compress and fix the magnet 2, the structural strength and rigidity of the riveting wall 5 are improved, and the stability and reliability of the riveting structure of the riveting wall 5 to the magnet 2 are improved.

The riveting wall 5 is an annular wall or the riveting wall 5 comprises a plurality of riveting convex sheets arranged along the circumferential direction of the base body 1. The riveting wall 5 is an annular wall, and can rivet and fix the magnet 2 from each position of the seat body 1, the riveting position is more flexible, and the annular magnet 2 or the bar-shaped magnet 2 can be well riveted and fixed.

In another embodiment, the magnet 2 is a bar, the mounting groove 3 is a bar groove, and the shape of the bar groove is matched with the shape of the magnet 2. The mounting grooves 3 are two and are respectively positioned on the side walls of two sides of the seat body 1, the two mounting grooves 3 are oppositely arranged to form a groove structure with the cross section matched with the axial projection shape of the magnet 2, and therefore effective guiding and limiting effects can be achieved for mounting the magnet 2.

The magnet 2 is strip-shaped or annular, the mounting groove 3 is a circular groove, and the magnet 2 is arranged in the circular groove. When mounting groove 3 was the circular slot, no matter be magnet 2 for strip or cyclic annular, can both install in mounting groove 3 smoothly, consequently, only need rationally set up the position of riveting wall 5 according to the structural configuration of magnet 2, just can effectively realize fixing the riveting of magnet 2.
