Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-5, a deodorization same-layer drainage check valve comprises a valve body 1, a valve cover 2 is arranged at the upper end of the valve body 1, the valve cover 2 is hermetically installed at the top end of the valve body 1, a water inlet pipe 3 is arranged at the front end of the valve body 1, a water outlet pipe 4 is correspondingly arranged at the rear end of the valve body 1, a check seat 5 is additionally arranged inside the valve body 1, the check seat 5 is communicated with the water inlet pipe 3, a one-way check cover 8 is movably installed on the check seat 5, and a sealing silica gel sheet 12 is arranged on the inner side surface of the one-way check cover 8.

In this embodiment, inlet tube 3 and outlet pipe 4 all are integrative injection moulding's with valve body 1 and mould the piece, have guaranteed the structural strength and the connection leakproofness of whole valve to inlet tube 3 is in same straight line with the center of outlet pipe 4, has effectively guaranteed that rivers are unobstructed.

In this embodiment, in order to get rid of the spring structure that the inside one-way valve spare installation of traditional check valve adopted, set up one and mould the non return seat 5 of piece with 1 integrative injection moulding of valve body, non return seat 5 is right trapezoid, and the inner wall of valve body 1 is hugged closely on its vertical limit, and a apopore 6 has been seted up to non return seat 5's inside, and apopore 6 communicates with inlet tube 3 with the specification, guarantees that the water route is unblocked.

Meanwhile, the top surface of the check seat 5 is provided with a mounting groove 7, the one-way check cover 8 mainly comprises a sealing cover 10, a mounting rotating shaft 11 and a sealing silica gel sheet 12, and the one-way check cover 8 is movably mounted in the mounting groove 7 through the mounting rotating shaft 11, so that the one-way check cover 8 can rotate up and down in the mounting groove 7 around the mounting rotating shaft 11 to realize opening and closing.

In this embodiment, in order to further guarantee one-way non return lid 8 pivoted smoothly, the arc wall that the bottom surface of mounting groove 7 formed for laminating installation pivot 11, valve gap 2's bottom surface is equipped with two spacing archs 9 in the position that corresponds mounting groove 7, and spacing arch 9 just in time supports the both ends top at installation pivot 11, prevents that the top space is too much to lead to installation pivot 11 to break away from mounting groove 7 or blocked in the clearance, influences the work of one-way non return lid 8.

In this embodiment, the sealing silicone piece 12 is fixedly mounted on the inner side surface of the sealing cover 10, and the sealing cover 10 and the sealing silicone piece 12 are attached to the inclined surface of the non-return seat 5 and correspond to the position of the water outlet hole 6 to play a role in blocking the non-return.

It should be noted that, in practical use of the valve, when water is drained normally, water flows into the water outlet hole 6 inside the check seat 5 through the water inlet pipe 3, and the one-way check cover 8 is jacked up under the impact of the water flow, so that the water flows continuously through the valve body 1 and flows out through the water outlet pipe 4 to form a complete and smooth pipeline, when water is not drained from the upper side, the one-way check cover 8 falls due to self weight and is just blocked at the outlet of the water outlet hole 6, at this time, if the peculiar smell gas flows back at the downstream, firstly, the peculiar smell gas flows into the valve body 1 through the water outlet pipe 4, and the only water outlet hole 6 is blocked by the one-way check cover 8, and the larger the pressure of the backflow is, the tighter the one-way check cover 8 is blocked by pressure, so that the check function is achieved.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
