Description

Groove type muffler bottom valve

technical field

The utility model relates to the field of bottom valves, in particular to a groove type noise-eliminating bottom valve.

Background technique

The bottom valve is a one-way channel that can prevent the backflow of liquid in the channel. The bottom valve is usually composed of valve body, valve disc, valve cover and other components. When the liquid enters the valve body from the inlet of the bonnet, under the pressure of the fluid, the valve disc is flushed away, that is, the channel is opened; Unimpeded pumping and saving water energy loss. However, due to the pressure of the fluid, the water flow is fast and the noise is large, and most of the bottom valves are connected by flanges, which need to be fixed by multiple bolts. The installation is complicated, labor-intensive and time-consuming, and the efficiency is low.

Utility model content

In order to overcome the above-mentioned disadvantages in the prior art, the purpose of this utility model is to provide a groove type noise-absorbing bottom valve which is simple in structure, easy to install, and can be quickly connected with pipelines.

The utility model is realized through the following technical scheme: the groove type noise-absorbing bottom valve includes an upper valve body and a lower valve body, the upper valve body and the lower valve body are fixed by bolts, and the upper valve body and the lower valve body are arranged There is a valve seat, the valve seat is provided with a drain port, and a valve clack that cooperates with the drain port is provided in the upper valve body, and a nozzle connected to the pipeline is also provided at the upper end of the upper valve body, and the outer surface of the nozzle is provided with groove, the lower end of the lower valve seat is provided with a grid support, and the lower end of the grid support is provided with a plurality of sound-absorbing baffles arranged obliquely along the horizontal.

Further, the noise-absorbing baffle of the utility model adopts an aluminum sheet.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. The utility model is provided with an obliquely installed muffler baffle under the drain outlet. The muffler baffle can reduce the slow drainage and prevent the pressure water from being discharged to the drain outlet instantly, which can improve the muffler effect and the check speed of the valve. Realize the function of noise reduction and anti-return.

2. The utility model adopts grooved connection installation, which reduces the installation process and bolt consumption, and the installation is simple and fast, which effectively improves the work efficiency and saves manpower, and has the value of wide popularization and application.

Description of drawings

Other features, objects and advantages of the present invention will become more apparent by reading the detailed description of non-limiting embodiments with reference to the following drawings:

Fig. 1 is the structural representation of the utility model.

Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, but should not be construed as limiting the present utility model.

In describing the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", The orientations or positional relationships indicated by "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention. Novel and simplified descriptions do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the utility model. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a flexible connection. Detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can also be direct connection or indirect connection through an intermediary, and it can be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present utility model in specific situations.

A groove type noise-absorbing bottom valve of this embodiment, as shown in Figure 1, includes an upper valve body 1 and a lower valve body 2, the upper valve body 1 and the lower valve body 2 are fixed by bolts, and the upper valve body 1 A valve seat 3 is arranged between the lower valve body 2, a drain port 4 is arranged on the valve seat 3, and a disc 5 cooperating with the drain port 4 is arranged in the upper valve body 1, and the upper end of the upper valve body 1 is also There is a nozzle 6 connected to the pipeline, the outer surface of the nozzle 6 is provided with a groove 7, the lower end of the lower valve seat 2 is provided with a grid support 8, and the lower end of the grid support 8 is provided with a horizontally inclined A plurality of muffler baffles 9 are arranged in a row. The muffler baffles 9 are located below the drain outlet, and the pressure water is drained to the drain outlet. The obliquely installed muffler baffles 9 can reduce the slow drainage and prevent the pressure water from going to the drain outlet instantly. Discharge can improve the noise reduction effect, increase the valve check speed, and realize the noise reduction and check function.
