[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. Valves are control components in fluid conveying systems, and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves can be connected to external pipes through joint connectors. Valves are mostly installed off the ground. When screwing, the installer needs to hold a tool in each hand to screw and install. The valve needs to be lifted. Since the valve is heavy, two people need to cooperate to align the flange holes and install it with screws, which requires extra manpower and wastes labor. The shaking of the valve when it is lifted affects the alignment of the flange holes, reducing the installation speed and efficiency. Therefore, a new type of valve connector that is easy to install is designed to change the above technical defects. Utility Model Content

[0005] When using the valve connector of the present technical solution, the user holds the fixed flange against the installation end of the valve body, then rotates the fixed flange so that its outer side enters the positioning hook, and the outer side of the fixed flange slides in the positioning hook and contacts the surface of the positioning plate, so that the flange holes of the valve body and the fixed flange are aligned, and the initial positioning of the fixed flange and the valve body is achieved, and screws are used for installation. The screws and nuts are passed in to fix them, and the baffle is rotated to contact and fix the screws and nuts, avoiding the need for staff to hold additional tools to fix the screws and nuts, and avoiding the traditional valve off-the-ground installation. Since the valve is heavy, two people are required to cooperate to align the flange holes and use screws for installation, which requires additional manpower and wastes labor, and the shaking of the valve when it is lifted affects the alignment of the flange holes, reducing the installation speed and efficiency.

DETAILED DESCRIPTION

[0014] This specific implementation is a valve connector that is easy to install, and its structural diagram is as follows Figure 1-Figure 4 As shown, the valve connector includes a valve body 5, both sides of the valve body 5 are provided with fixed flanges 1, both ends of the valve body 5 are fixedly connected with four positioning hooks 12, and the inner walls of the positioning hooks 12 are fixedly connected with positioning plates 11, the outer surface of the positioning hook 12 is provided with a limiting hole 13, the fixed flange 1 is slidably installed inside the positioning hook 12, the fixed flange 1 and the valve body 5 are installed by screws 7, and the nut of the screw 7 is located inside the limiting hole 13, and the outer surface of the positioning hook 12 is fixedly and rotatably installed with a baffle 2.

[0015] Among them, a positioning piece 4 is slidably installed on the outside of the valve body 5, a positioning hole 14 is opened on the outer surface of the positioning piece 4, a mounting piece 6 is fixedly connected to the outer surface of the positioning piece 4, a screw 3 is arranged on the outside of the mounting piece 6, a mounting hole 8 is opened on the outer surface of the mounting piece 6, and a thread hole 10 is opened on the outer surface of the positioning hook 12, and the diameter of the positioning hole 14 is equal to the diameter of the screw 7. Through the arrangement of the screw 3, the positioning piece 4, the mounting piece 6, the mounting hole 8, the thread hole 10 and the positioning hole 14, the staff pulls the positioning piece 4 to slide on the surface of the valve body 5, so that the threaded end of the screw 7 is inserted into the inside of the positioning hole 14, the positioning piece 4 conflicts with the nut of the screw 7, and the mounting hole 8 and the thread hole 10 overlap at this time. The screw 3 is used to pass through the mounting hole 8 and screw into the inside of the thread hole 10 to fix the mounting piece 6 and the positioning piece 4, so as to fix the nut of the screw 7 and prevent the screw 7 from loosening and affecting the connection effect.

[0016] In addition, the outer surface of the positioning piece 4 is fixedly connected with a protective ring 9, and the material of the protective ring 9 is rubber. Through the setting of the protective ring 9, the protective ring 9 is used to cover the screw 7 nut to protect it, so as to prevent the screw 7 nut from contacting with rainwater and causing rust.

[0017] Working principle: When using the valve connector of the present technical solution, the user holds the fixed flange 1 against the installation end of the valve body 5, and then rotates the fixed flange 1 so that its outer side enters the positioning hook 12. The outer side of the fixed flange 1 slides in the positioning hook 12 and contacts the surface of the positioning plate 11, so that the flange holes of the valve body 5 and the fixed flange 1 are aligned, and the initial positioning of the fixed flange 1 and the valve body 5 is achieved. The screws 7 are used for installation, and the nuts of the screws 7 are inserted into the limiting holes 13 for fixing. The baffle 2 is rotated to contact and fix the nuts of the screws 7, so that the staff does not need to hold additional tools to fix the nuts of the screws 7, and avoids the traditional valve being installed off the ground. Since the valve is heavy, two people are required to cooperate to align the flange holes and use screws for installation, which requires additional manpower and wastes labor. In addition, the shaking of the valve when it is lifted affects the alignment of the flange holes, reducing the technical problem of installation speed and efficiency.
