Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises the union female 1, elbow 2 and the union male 3 that connect successively,
The left side cover of described union female 1 is embedded with union ring 4,
The left side of described elbow 2 is enclosed within the right side of described union female 1, and its right side is threaded with the left side of described union male 3,
The right side of described union female 1 is disposed with the first square circular groove 5, one or two or multiple lower semi-circular circular groove 6 and the first ring-shaped step 7 of depression to the left from inside to outside,
The left side of described elbow 2 and the first square circular groove 5 of described union female 1, one or two or multiple lower semi-circular circular groove 6 and to the left the first ring-shaped step 7 corresponding section ecto-entads of depression be disposed with the second square circular groove 8, one or two or multiple first circular circular groove 9 and the second ring-shaped step 10 of depression to the right, above described first circular circular groove 9, be provided with the through hole that stops up screw 11
In the space that described the first square circular groove 5 and described the second square circular groove 8 form, be provided with O-ring seal 12,
