Description

TECHNICAL FIELD

[0001] The utility model relates to four -way valve connecting device technical field especially a four -way valve connecting device. BACKGROUND

[0002] The connecting mode between the existing four -way valve and straight pipe is that a threaded hole is pre -processed on the specific position of the outer wall of the four -way valve. The original intention of this design is to realize the stable connection between the four -way valve and the flange on the straight pipe by utilizing these threaded holes, cooperating with the screw rod and nut as fastening elements. However, this connection scheme has a relatively obvious limitation: since the position of the threaded hole on the outer wall of the four -way valve is pre -set and fixed, it means that each four -way valve can only correspond to install a specific specification type of straight pipe flange.

[0003] This single correspondence in design greatly limits the flexibility and universality of the four -way valve in actual application. Once the situation of connecting different specifications of straight pipe flanges is encountered, the existing four -way valve cannot meet this demand because the position and specification of the threaded hole cannot be adapted to other size flanges. This not only increases the cost of procurement and storage, but also may cause the failure to find a suitable four -way valve to complete the construction of the pipeline system in some specific application scenarios, thereby causing unnecessary trouble and delay to the engineering implementation.
