Example 1

As shown in fig. 1-2, which is a preferred embodiment of the present utility model, the differential pressure combined valve includes a valve body 1 and a socket 2, wherein a connection hole 11 is provided on the valve body 1, a connection part 21 is provided on the socket 2, the connection part 21 is screwed into the connection hole 11 to fix the socket 2 and the valve body 1, in this embodiment, the socket 2 is square, four sides of the socket 2 are provided with a horizontal plate 3 extending horizontally, a first fixing hole 31 is provided at an end of the horizontal plate 3, four second fixing holes 12 with the same aperture as the first fixing hole 31 are provided on the valve body 1, that is, the second fixing holes 12 are matched with the first fixing holes 31 one by one, and a fixing rod 4 is screwed into each pair of matched first fixing holes 31 and second fixing holes 12.

During installation, the sleeve joint 2 is screwed to the position that the first fixing hole 31 and the second fixing hole 12 are positioned on the same horizontal line, and the sleeve joint 2 can be fixedly connected to the valve body 1 by simultaneously screwing the fixing rod 4 into the first fixing hole 31 and the second fixing hole 12.

Compared with the prior differential pressure combined valve which fixes the socket joint 2, the differential pressure combined valve provided by the implementation has the advantages that the number of components arranged in the differential pressure combined valve is small, the structure is simple, and the mass production is convenient; as long as one fixing rod 4 does not fall off, the socket 2 is not loosened, and the socket 2 is fixed more firmly and reliably.

Example 2

The differential pressure combined valve inner joint 2 in embodiment 1 is screwed into the valve body 1, which is closer to the structure of the existing differential pressure combined valve, however, in the process of rotating the joint 2, the first fixing hole 31 and the second fixing hole 12 need to be located on the same line, which requires higher accuracy in rotating the joint 2, and reduces the assembly efficiency of the joint 2 and the valve body 1.

On the basis of embodiment 1, the surfaces of the connecting portion 21 and the connecting hole 11 are smooth, that is, the connecting portion 21 is movably attached to and fixed in the connecting hole 11, and when in connection, the fixing wire is connected in the second fixing hole 12 by connecting the fixing wire in the first fixing hole 31 and then rotating the sleeve joint 2 until the fixing wire is aligned with the second fixing hole 12. In the whole installation process, the socket joint 2 and the valve body 1 are movably connected, so that the socket joint 2 can be rotated relatively conveniently.

Further, four positioning columns 5 protruding vertically are arranged on the valve body 1, and positioning holes 32 matched with the positioning columns 5 are formed in the horizontal plate 3. When the sleeve joint 2 is installed, the positioning hole 32 is aligned with the positioning column 5, so that the first fixing hole 31 and the second fixing hole 12 can be adjusted to be positioned on the same straight line, the process of adjusting the sleeve joint 2 is omitted, and an operator can conveniently and rapidly install the sleeve joint 2 on the valve body 1.

In this embodiment, the positioning post 5 penetrates through the positioning hole 32, and a positioning nut 51 attached to the horizontal plate 3 is screwed to the end of the positioning post 5. The cooperation of locating nut 51 and reference column 5 further avoids the cover joint 2 to take place not hard up, improves its stability with valve body 1 fixed connection.
