DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4, a valve that is easy to install, includes a valve body 1, a support plate 2, a centering component and a clamping component, the support plate 2 is arranged below the valve body 1, the centering component includes a first handle 3, a first positive and negative thread screw 4 and a first slider 5, a first slide groove is arranged above the left and right sides of the support plate 2, the first positive and negative thread screw 4 passes through the first slide groove and is connected to the first handle 3, the first slider 5 is symmetrically arranged in the first slide groove, the first slider 5 is threadedly connected to the first positive and negative thread screw 4, a second slide groove is arranged on the first slider 5, the clamping component includes a second positive and negative thread screw 6, a second handle 7, a second slider 8 and a clamping plate 9, the second slide groove is arranged with the second positive and negative thread screw 6 and two groups of symmetrically arranged second sliders 8, the second slider 8 is threadedly connected to the second positive and negative thread screw 6, the second positive and negative thread screw 6 protrudes from the second slider 8 and is connected to the second handle 7, and the clamping plate 9 is arranged on the second slider 8.

[0023] During actual use, first, the second handle 7 is used to drive the corresponding second forward and reverse threaded screw 6 to rotate, and the two groups of second sliders 8 move toward each other. The clamping plate 9 above the second slider 8 clamps the corresponding docking tube. At first, the gap between the two groups of first sliders 5 is large, and the support plate 2 provides stable support for the first slider 5. The first slider 5 provides stable support for the second forward and reverse threaded screw 6 and the second slider 8. The first handle 3 is used to drive the first forward and reverse threaded screw 4 to rotate, and the two groups of first sliders 5 move toward each other. The two groups of butt joints clamped are stably connected to the joint of the valve body 1, which reduces the operating accuracy of the staff and is convenient to use. At the same time, the centering component cooperates with the clamping component to prevent the butt joint from loosening.
