Embodiment Construction
[0015] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0016] Described in the present invention is a combined check valve, such as figure 1 to combine figure 2 and image 3 As shown, it includes a conical head and a fixed end. The conical head includes a conical structure 1 and a cylindrical structure 2 at one end of the conical structure 1. The two symmetrical sides of the cylindrical structure 2 are concavely provided with a limiting plane 3, so The center of one end of the cylindrical structure 2 of the tapered head is provided with a slot 4, and the fixed end includes a T-shaped fixed head and a bolt 5, and the T-shaped fixed head includes a top circular column 6 and a lower fixed column 7, One end of the bolt 5 is fixed on the bottom of the...

The invention discloses a combined type check valve. The combined type check valve comprises a conical head and a fixing end. The conical head comprises a circular truncated cone structure and a cylinder structure located at one end of the circular truncated cone structure. Limiting planes are arranged on the two symmetrical edges of the cylinder structure in an inwardly concave mode. A slot is formed in the center of one end of the cylinder structure of the conical head. The fixing end comprises a T-shaped fixing head and a bolt. The T-shaped fixing head comprise a circular column located at the top and a fixing cylinder located on the lower portion. One end of the bolt is fixed to the bottom of the fixing cylinder. The bolt corresponds to the slot. Three sliding grooves are formed in the T-shaped fixing head at equal intervals from top to bottom. The check valve is of the combined structure and is reasonable in structure; product waste is reduced, and the energy-saving performance is high; meanwhile, repairing and maintaining are convenient, the replacement cost is low, and the service life is long.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to a combined check valve. Background technique [0002] Check valve (also known as check valve) refers to a valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the medium from flowing backward. It is also called check valve, one-way valve, reverse flow valve, and back pressure valve. It belongs to an automatic valve, its main function is to prevent the reverse flow of the medium, prevent the reverse rotation of the pump and the drive motor, and release the container medium; it can also be used to supply the auxiliary system whose pressure may rise above the system pressure. . [0003] Most of the check valves used in the prior art have an integrated structure, which cannot be easily replaced and maintained during use, and is inconvenient to use. Contents of the invention [0004] The purpose of the present invention is to pr...
