Today Huaheng Instrument will introduce a national utility model patent – ​​a flange butterfly valve that is easy to install.
Description

The utility model relates to the technical field of valves, in particular to a flange butterfly valve which is easy to install.

Background of the invention

In the field of engineering pipeline transportation, the use of valves is very extensive. Now the basic structure of the valve is to coaxially seal the embedded valve seat in the valve body. The valve body is radially mounted with the valve stem, and the valve plate is fixed on the valve stem of the valve body. The plate is sealingly matched with the valve seat, and the valve plate is swung or moved under the driving of the valve stem to open and close the flow passage in the valve seat; the valve body is radially provided with a plurality of flanges for connecting with the pipe, and the flange plate is made There are bolt mounting holes.

However, since the valve is used on pipes of different specifications, the conventional mounting hole flange plate has more standard size restrictions and is inconvenient to install. Therefore, we have made improvements to this and proposed a flange butterfly valve that is easy to install.

Summary of the invention

The main purpose of the utility model is to provide a flange butterfly valve which is easy to install, and can effectively solve the problem that the valve is used for different specifications of the pipe as proposed in the background art, and the conventional mounting hole flange plate has more standard size restrictions and installation Inconvenience.

 

The utility model relates to an overall structure diagram of a flange butterfly valve which is easy to install

In order to achieve the above object, the technical solution adopted by the utility model is as follows: an easy-to-install flange butterfly valve, comprising a valve tube, the outer wall of the valve tube is fixedly connected with a valve plate adjusting head, and the valve plate adjusting head is mounted thereon The adjusting plate is connected to the valve plate mounted on the valve tube, and the first flange is fixedly connected to both ends of the valve tube, and the first flange is provided on the ring wall a plurality of first screw holes, the first flange is threadedly connected to the second flange through the first screw hole, and the second flange is provided with a plurality of flange holes, the inner wall of the valve tube A first groove is opened, and the valve tube is sleeved with a sealing rubber ring through the first groove.

Further, one side of the inner ring of the second flange is provided with a second groove, and the groove wall of the second groove is provided with a plurality of second screw holes. The second groove is sized to match the first flange. The distribution of the first screw hole on the first flange corresponds to the distribution of the second screw hole on the groove wall. The sealing rubber ring is matched to the first groove size.

Compared with the prior art, the utility model has the following beneficial effects: the flange butterfly valve which is easy to install, by providing the first flange and the second flange which can be engaged, can be installed according to different The installation needs to replace the second flange of different sizes for easy installation; the screw plate is provided to make the valve plate adjustment head can be installed at a wider angle; and the sealing rubber ring is provided to increase the sealing performance of the butterfly valve.
