A plurality of limiting blocks are integrally connected to the side surface of the connecting pipe. The limiting blocks are arranged in a fan shape. One end of the main valve body facing the connecting pipe is provided with a receiving groove for receiving a plurality of limiting blocks. The main valve body is provided with a communication groove that communicates with the receiving groove and is used for the limiting blocks to be inserted into the receiving groove. A fastening bolt is threadedly connected to the side surface of the main valve body.

[0005] By adopting the above technical solution, the limiting blocks are placed into the receiving groove along the communication groove, so that the connecting pipe is connected to the main valve body. Then, the fastening bolt is rotated to squeeze and fix the connecting pipe, so that the connecting pipe and the main valve body are in a relatively fixed connection state, achieving the purpose of adjusting the connecting pipe. The fan-shaped setting increases the contact area between the limiting blocks and the groove wall of the receiving groove.

[0006] As a further scheme of the utility model: a fixing plate is integrally connected to the side surface of the connecting pipe, and a reinforcing plate is integrally connected to the side surface of the connecting pipe and located on the side surface of the fixing plate.

[0007] By adopting the above technical solution, the setting of the fixing plate facilitates the installation of the connecting pipe, and the setting of the reinforcing plate increases the strength of the connecting pipe itself.

[0008] As a still further scheme of the utility model: a valve rod is included in the main valve body. One end of the valve rod located in the main valve body is connected with a sphere. The main valve body is integrally connected with a mounting plate located in the circumferential direction of the valve rod, and a connecting block is integrally connected to the side surface of the mounting plate.

[0009] By adopting the above technical solution, the settings of the mounting plate and the connecting block facilitate the installation of other components connected to the main valve body.

[0010] Preferably, annular grooves are provided on the side surfaces of both the connecting pipe and the valve rod, and sealing rings are installed in the annular grooves.

[0011] Preferably, three limiting blocks are provided and are equidistantly distributed about the center of the end face of the connecting pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Put the limiting block into the receiving groove along the communicating groove, so that the connecting pipe is connected to the main valve body. Then rotate the fastening bolt to squeeze and fix the connecting pipe, so that the connecting pipe and the main valve body are in a relatively fixed connection state, achieving the purpose of adjusting the connecting pipe. The fan-shaped setting increases the contact area between the limiting block and the groove wall of the receiving groove. Description of the Drawings
