DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1 , Figure 2 and Figure 4 , is the first embodiment of the utility model, which provides a cast iron connector with adjustable pressure, including a first connector 1 and a second connector 2 that are spliced ​​together. The first connector 1 and the second connector 2 can firmly splice two pipes, and a pressure regulating mechanism is arranged on the second connector 2. The pressure regulating mechanism includes a water pump 5 installed on the second connector 2, which realizes the addition of the water pump 5, and a pressure pipe 8 arranged inside the second connector 2, which realizes the addition of the pressure pipe 8. One end of the water pump 5 extends to the inside of the second connector 2 and is connected to the pressure pipe 8. A first connecting portion 81 and a second connecting portion 82 are arranged inside the second connector 2, and the first connecting portion 81 and the second connecting portion 82 are both connected to the pressure pipe 8, which realizes the addition of the first connecting portion 81 and the second connecting portion 82. When water is transported, it can flow into the inside of the water pump 5 and then flow out, so that the pressure is increased, which solves the problem that the traditional cast iron connector cannot achieve pressure regulation.

[0023] In this embodiment, preferably, the water pump 5 and the second joint 2 are connected by screws, so that the water pump 5 and the second joint 2 are firmly spliced, and the first fastener 3 and the second fastener 4 are provided on the outer side of the splicing end of the first joint 1 and the second joint 2, and the first fastener 3 and the second fastener 4 are cooperated to increase the firmness of the splicing of the first joint 1 and the second joint 2.

[0024] In the present embodiment, preferably, it also includes a first fastening ear 6 symmetrically arranged at the end of the first fastener 3, so as to realize the addition of the first fastening ear 6, and a second fastening ear 7 symmetrically arranged at the end of the second fastener 4, so as to realize the addition of the second fastening ear 7, and the first fastening ear 6 and the second fastening ear 7 are connected by bolts and nuts, and the first fastening ear 6 and the second fastening ear 7 are firmly spliced ​​by the cooperation of the bolts and nuts, thereby helping to increase the firmness of the first fastener 3 and the second fastener 4 in fixing the first joint 1 and the second joint 2.
