Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a gate valve body casting structure. Background Art

[0002] The flat gate valve is a gate valve whose opening and closing action is a linear motion. It has a flat closing element perpendicular to the fluid. The closing member can be a single gate or a double gate with an opening mechanism in between. The user controls the up and down movement of the flat closing member through the operating valve handle fixedly connected to the closing member, thereby realizing that the flat closing member slides into the fluid and closes the fluid flow.

[0003] The flat gate valve in the prior art mainly includes a valve body casting and an opening and closing part for controlling the flow of the medium inside the valve body casting. When a large valve body casting needs to be transported, it is usually necessary to use a gantry hanger or a crane arm to move the valve body casting. However, when the surrounding environment does not allow the gantry hanger or the crane arm to enter, it can only be transported manually, and the large valve body casting will cause great inconvenience to manual transportation.

[0004] An existing patent (publication number: CN218598925U) discloses a gate valve body casting structure, which transports the casting body through a moving component. The setting of the moving component improves the restrictions on the transportation work caused by the surrounding environment; at the same time, the fixed component can prevent the first bracket and the second bracket from being separated when the casting body is transported, thereby improving the stability of the first bracket and the second bracket when connected during transportation.

[0005] However, the above technical solution still has certain defects. Its fixing component fixes the first bracket and the second bracket by means of a binding rope, a hook and a locking column. On the one hand, when fixing the two groups of brackets, the operator needs to sequentially hang the hook fixed at one end of the binding rope on the locking column, which is time-consuming and labor-intensive. On the other hand, the binding rope itself has a certain elasticity, which makes the operator's moving component shake when moving the casting body, affecting the stability of the overall movement. For this reason, a gate valve body casting structure is proposed. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a gate valve body casting structure to solve the technical problems raised in the above background.

[0007] To achieve the above object, the utility model provides the following technical solutions: a gate valve body casting structure, comprising a casting body, a moving assembly is arranged outside the casting body, the moving assembly comprises two pairs of arc-shaped brackets rotatably arranged outside the casting body, the two arc-shaped brackets in the same pair are arranged symmetrically, and the two arc-shaped brackets in the same pair are positioned by a fixing assembly;

[0014] As a preferred technical solution of the gate valve body casting structure of the present utility model, reinforcing ribs are fixedly installed on the outer side wall of the casting body.

[0015] To sum up, the present utility model mainly has the following beneficial effects:

[0016] 1. By pulling the handle of the present utility model, the fixed insertion rod and the fixed ring are driven to move upward until the fixed insertion rod disengages from the limit groove on the docking column, releasing the fixation of this pair of arc-shaped brackets.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0028] The following will describe the embodiments according to the overall structure of the present utility model.

[0029] A gate valve body casting structure, as Figures 1-5 shown, includes a casting main body 100. A moving component 200 is arranged outside the casting main body 100. The moving component 200 includes two pairs of arc-shaped brackets 230 rotatably arranged outside the casting main body 100. The two arc-shaped brackets 230 in the same pair are symmetrically arranged, and the two arc-shaped brackets 230 in the same pair are positioned by a fixing component 300; the fixing component 300 includes fixing rods 310 fixedly installed on one side of the two arc-shaped brackets 230 in the same pair. One end of each fixing rod 310 away from the arc-shaped bracket 230 is fixedly connected with a positioning sleeve 320. A fixing sleeve 330 is fixedly connected to the top of the outer wall of each positioning sleeve 320. A fixing insertion rod 340 is longitudinally arranged in the fixing sleeve 330. The bottom end of the fixing insertion rod 340 penetrates and extends into the positioning sleeve 320. A fixing ring 350 is fixedly sleeved on the outer wall of the fixing insertion rod 340 inside the fixing sleeve 330. A limiting spring 360 is fixedly connected between the fixing ring 350 and the top of the inner cavity of the fixing sleeve 330. A docking column 380 is horizontally sleeved in the two positioning sleeves 320. Four limiting grooves 390 matching the fixing insertion rod 340 are formed on the outer wall of the docking column 380. The limiting spring 360 is sleeved on the outside of the fixing insertion rod 340, and the limiting spring 360 is in a compressed state in the initial state. The top end of the fixing insertion rod 340 penetrates and extends outside the fixing sleeve 330 and is fixedly installed with a pulling handle 370.

[0030] When the surrounding environment does not allow the gantry hanger or the jib to enter, the fixing of the arc-shaped bracket 230 by the fixing component 300 can be released first. By pulling the pull handle 370, the fixing plug 340 and the fixing ring 350 are driven to move upward. The upward movement of the fixing ring 350 further compresses the limit spring 360 until the fixing plug 340 disengages from the limit groove 390 on the docking column 380. After releasing the pull handle 370, the fixing of this pair of arc-shaped brackets 230 is released. Then, the docking column 380 is pulled out. Next, by rotating the arc-shaped bracket 230, the moving component 200 is rotated to the lower part of the casting body 100. Subsequently, the pull handle 370 is continuously pulled, and the docking column 380 is passed through the two positioning sleeves 320 until the other pair of limit grooves 390 is aligned directly below the fixing plug 340. After releasing the pull handle 370, the limit spring 360 uses its own elastic force to push the fixing ring 350 and the fixing plug 340 to re-insert into the limit groove 390, completing the fixing of the moving component 200, ensuring that the two pairs of arc-shaped brackets 230 will not separate from each other during the handling work, further improving the stability when they are connected, and also improving the stability of the handling.

[0031] Please refer particularly to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the moving component 200 further includes a plurality of connecting sleeves 210 which are symmetrically arranged and fixedly connected to the outer side wall of the casting body 100. A guide rod 220 is coaxially connected inside each connecting sleeve 210. Each pair of arc-shaped brackets 230 is respectively slidably connected to its corresponding guide rod 220, and the arc-shaped bracket 230 is rotationally connected to the casting body 100 through the guide rod 220. A buffer component 240 is fixedly installed at one end of each arc-shaped bracket 230 away from the guide rod 220. An installation seat 250 is fixedly connected to the top end of each group of buffer components 240. A threaded hole is opened on the other side of each group of installation seats 250, and a screw rod 280 is threadedly connected in the threaded hole. The other end of the screw rod 280 is fixedly connected to an installation base plate 260, and a universal wheel 270 is installed on the other side of the installation base plate 260.

[0032] When the ground has a certain inclination, the operator can move the arc bracket 230 along the guide rod 220 to a suitable position of the casting body 100 according to the inclination angle of the slope, so that the supporting position of the casting body 100 can be adjusted to ensure the stability of the casting body 100 during transportation. At the same time, when the moving device is not needed, the arc bracket 230 can accommodate and fit the casting body 100, reducing the overall occupied space. When the casting body 100 is transported by relying on the moving component 200, the distance between the universal wheel 270 and the casting body 100 can be adjusted by rotating the mounting base plate 260 to drive the screw 280 to rotate, thereby ensuring that when the casting body 100 is transported, the height of the casting body 100 is in an appropriate position, ensuring that the transportation of the casting body 100 is carried out smoothly.

[0033] Please refer to Figure 2 and Figure 5 As shown, the buffer assembly 240 includes four dampers 241 fixedly mounted between the arc-shaped bracket 230 and the mounting seat 250, and a buffer spring 242 is sleeved on the outside of each damper 241, one end of the buffer spring 242 is fixedly connected to the end face of the arc-shaped bracket 230, and the other end is fixedly connected to one end of the mounting seat 250.

[0034] When the ground is uneven, the buffer assembly 240 is provided to improve the stability of the overall movement of the device, reduce the bumps during the movement of the valve body, and provide a certain degree of protection for the valve body, thereby extending the service life of the valve body.

[0035] Please refer to Figure 1 and 2 As shown, the inner wall of each arc-shaped bracket 230 is provided with a buffer pad 290 for fitting with the outer wall of the casting body 100 .

[0036] When the arc-shaped bracket 230 is rotated to the top of the casting body 100 and is stored, the buffer pad 290 will fit together with the outer wall of the casting body 100. At this time, the buffer pad 290 can reduce the impact of the arc-shaped bracket 230 on the casting body 100 when it is hit by an external impact, thereby providing a buffering and protective effect on the casting body 100.

[0037] Please refer to Figure 1 As shown, a reinforcing rib 110 is fixedly mounted on the outer wall of the casting body 100 .

[0038] The provision of the reinforcing ribs 110 can improve the structural strength of the valve body, thereby reducing the probability of damage to the casting body 100 when it is subjected to external impact.

[0039] During use, when the surrounding environment does not allow the gantry hanger or the jib to enter, the fixing of the arc-shaped bracket 230 by the fixing component 300 can be released first. By pulling the pull handle 370, the fixing plug 340 and the fixing ring 350 are driven to move upward. The upward movement of the fixing ring 350 further compresses the limit spring 360 until the fixing plug 340 disengages from the limit groove 390 on the docking column 380. Then, the pull handle 370 is released to release the fixing of this pair of arc-shaped brackets 230. Subsequently, the docking column 380 is pulled out. Then, by rotating the arc-shaped bracket 230, the moving component 200 is rotated to the lower part of the casting body 100. Subsequently, the pull handle 370 is continuously pulled, and the docking column 380 is passed through the two positioning sleeves 320 until the other pair of limit grooves 390 are aligned directly below the fixing plug 340. Then, the pull handle 370 is released, and the limit spring 360's own elastic force is used to push the fixing ring 350 and the fixing plug 340 back into the limit groove 390 to complete the fixing of the moving component 200, ensuring that the two pairs of arc-shaped brackets 230 will not separate from each other during the handling work, further improving the stability when they are connected, and also improving the stability of the handling. The parts not involved in this device are the same as or can be implemented using the prior art.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
