Detailed Description
As shown in fig. 1 to 5, the connection device for liquid supply pipelines of this embodiment is used for connecting two liquid supply pipelines 100, the two liquid supply pipelines 100 are arranged oppositely, and a connection portion is formed between opposite ports of the two liquid supply pipelines 100, and the connection device for liquid supply pipelines of this embodiment includes two pipe clamps 1, a seal ring 2 and a protection sleeve 3, the seal ring 2 is sleeved outside the two liquid supply pipelines 100 and surrounds the connection portion, the protection sleeve 3 is sleeved outside the two liquid supply pipelines 100 and surrounds the seal ring 2, the two pipes are buckled together and connect the two liquid supply pipelines 100 together, and the two pipe clamps are wrapped outside the protection sleeve 3.
Specifically, the connection device for a liquid supply pipe according to the present embodiment additionally adds a protection cover 3 to the outside of the sealing ring 2 to protect the sealing ring 2. In the actual assembling process, the specific assembling steps are described as follows with reference to the attached drawings:
firstly, the protective sleeve 3 is sleeved on the end part of one of the liquid supply pipelines 100, as shown in the state of figure 3; then, the sealing ring 2 is sleeved on the end of the liquid supply pipeline 100 and is shielded by the protective sleeve 3, as shown in the state of fig. 4; thirdly, inserting another liquid supply pipeline 100 into the sealing ring 2, butting the ends of the two liquid supply pipelines 100 together, so that the sealing ring 2 wraps and seals the connecting part formed by the ends of the two liquid supply pipelines 100, and meanwhile, the protective sleeve 3 is sleeved on the ends of the two liquid supply pipelines 100, as shown in the state of fig. 5; finally, two pipe clamps 1 are mounted between the ends of the two liquid supply ducts 100, so as to connect the two liquid supply ducts 100 together by means of the two pipe clamps 1, as shown in the state of fig. 2.
In the above-mentioned operation process, even if take place crooked when the installation of pipe strap 1 appears, pipe strap 1 is screwing up the in-process through bolt 10, because of protective sheath 3 covers in the outside of sealing washer 2, the width of protective sheath 3 is greater than the width of sealing washer 2, and then can not take place pipe strap 1 and carry sealing washer 2 to ensure that sealing washer 2 can be reliable sealed.
For the mode of connecting the pipe clamp 1 with the two liquid supply pipelines 100, a plurality of annular positioning grooves 101 may be formed on the outer pipe wall of the end portion of the liquid supply pipeline 100, raised positioning ribs 11 are formed on the inner wall of the pipe clamp 1, and the positioning ribs 11 are inserted into the corresponding positioning grooves 101.
