Description

Technical Field

[0001] The utility model relates to the technical field of valve installation, in particular to a valve structure which is easy to install. Background Art

[0002] Valves are control components in fluid conveying systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow and pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, ranging from simple stop valves to highly complex automatic control systems. Common valve installation methods include threaded, flanged, welded, clamped, and ferrule-type connections. However, the installation of valves in larger pipelines is often difficult for a single person to complete. Multiple personnel are required to support, locate, and position the connection ends before making the final connection, which is labor-intensive. Therefore, a structure that facilitates valve installation is needed to assist in this process.

[0003] For example, a structure for facilitating valve installation disclosed in the authorization announcement number CN217272198U includes a valve body, a valve cover mounted on the valve body, an operating rod rotatably mounted on the valve cover, a water inlet pipe mounted on the valve body, and two fixing rings, the two fixing rings are respectively located on both sides of the valve body and both fixing rings are fixed to the water inlet pipe, the two fixing rings are each provided with a plurality of bolt holes, a plurality of fixing components, the plurality of fixing components each including a pull plate mounted on the fixing ring, the pull plate having an "L"-shaped cross-section, a sliding component, the plurality of pull plates are mounted on the sliding component, the sliding component can drive the pull plate to slide on the fixing ring, and a positioning component, the positioning component can realize positioning of the fixing ring. This improves the efficiency of installation, reduces the labor cost during installation, avoids damage to the bolt holes caused by the valve's own weight, and increases its service life. However, this utility model lacks temporary support and fixing functions when the flange joints are butt-jointed and installed, making it inconvenient for workers to accurately locate and position the connection holes during installation, and is not convenient to use. To this end, we propose a valve structure that is easy to install, which solves the temporary support and fixing problems when the flanges are butt-jointed, and improves the convenience and practical effect of the utility model.

[0024] A valve structure that is easy to install includes a valve body 100. A water inlet pipe 101 is provided on one side of the valve body 100, and a water outlet pipe 102 is provided on the other side. Flange joints 103 are provided at the outer ends of the water inlet pipe 101 and the water outlet pipe 102. A first connecting mechanism is provided on the outer side of the water inlet pipe 101, and a second connecting mechanism is provided on the outer side of the water outlet pipe 102.

[0025] The first connecting mechanism includes a first movable ring 200, which is sleeved on the outside of the water inlet pipe 101. The first movable ring 200 has through holes 201 corresponding to the reserved mounting holes of the flange joint 103. A first semicircular support plate 202 is fixedly welded to the outside of the bottom of the first movable ring 200.

[0026] A first mounting block 203 is fixedly provided on the top of the first movable ring 200 . The first mounting block 203 is provided with a first through screw hole 204 . A first tightening bolt 205 is screwed into the first through screw hole 204 .

[0027] In this embodiment, preferably, one end of the first tightening bolt 205 is rotatably connected to the first bearing sleeve 206 , and the first bearing sleeve 206 is fixedly disposed on one side of the first clamping plate 207 .

[0028] In this embodiment, preferably, a first chute 209 is provided at the top of the water inlet pipe 101 , a first limiting slider 210 is provided on the inner wall of the first movable circle 200 , and the first limiting slider 210 is slidably connected along the first chute 209 .

[0029] In this embodiment, preferably, the inner diameter of the first movable ring 200 is consistent with the outer diameter of the water inlet pipe 101, the inner diameter of the first semicircular supporting plate 202 is consistent with the outer diameter of the flange joint 103, and the inner diameter of the through hole 201 is larger than the inner diameter of the reserved installation hole of the flange joint 103.

[0030] In this embodiment, preferably, three first clamping claws 208 are provided on the outer side of the first clamping plate 207 , and the first clamping claws 208 are evenly arranged in an array on the outer side of the first clamping plate 207 with the center of the first clamping plate 207 as a base point.

[0031] In this embodiment, preferably, the second connecting mechanism includes a second movable ring 300, a second semicircular support plate 301, a second slide groove 302, a second limiting slider 303, a second mounting block 304, a second through screw hole 305, a second tightening bolt 306, a second bearing sleeve 307, a second clamping plate 308 and a second clamping claw 309, and the first connecting mechanism has the same structure as the second connecting mechanism.

[0032] When using a valve structure that is easy to install in this embodiment, first connect the flange joint 103 to one end of the water inlet pipe 101, and push the first movable ring 200 to the back side of the connecting surface close to the flange joint 103 through the first slide groove 209 opened at the top of the water inlet pipe 101 and the first limiting slider 210 set on the inner wall of the first movable ring 200, and simultaneously drive the first semicircular supporting plate 202 to move to the bottom end of the flange joint 103 and be in a supporting state.

At this time, the staff can screw and preliminarily tighten the two reserved mounting holes on the left and right of the flange joint 103. Then, loosen the first clamping claw 208 and rotate the first clamping claw 208 until its lowest point on the horizontal plane is above the top surface of the flange joint 103. Then, move the first movable ring 200 toward the side of the valve body 100 along the first slide groove 209, so that the flange joint 103 is completely exposed, so that the installer can tighten the remaining reserved mounting holes. The operation method for connecting the flange joint 103 at one end of the outlet pipe 102 is the same as that for the water inlet pipe 101. Among them, the first semicircular support plate 202 and the second semicircular support plate 301 play the role of temporarily supporting the docking flange and assisting the docking flange to quickly position during installation; the first clamping claw 208 and the second clamping claw 309 play the role of temporary clamping and fixing during installation, so that the valve body 100 can be quickly connected and installed even by one person during the connection operation, which not only saves labor hours but also reduces the difficulty of the operation.
