The current cast iron valves are mainly fixed by flanges and bolts during use. However, most cast iron valves do not have a positioning structure during assembly, which requires manual support during assembly. When the hand slips, the position of the cast iron valve is easily shifted during assembly, thereby increasing the subsequent operation process. Utility Model Content
[0003] In order to overcome the above-mentioned defects, the utility model provides a cast iron valve which is easy to disassemble and assemble, which solves the problem that most cast iron valves do not have a positioning structure during assembly, resulting in the need for manual support of the cast iron valves during assembly. When the hands slip, the position of the cast iron valve may easily shift during assembly, thereby increasing the problem of subsequent operating procedures.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cast iron valve that is easy to disassemble and assemble, comprising a valve body, a valve core is rotatably connected in the valve body, one end of the valve body is connected to flange one, one side of the flange one is connected to flange two, one side of the flange two is connected to a pipe body, the outside of the flange two is connected to a sleeve plate, a cross groove is provided in the flange two, one side of the flange one is connected to a cross block, one side of the cross block is connected to an inclined block, the sleeve plate is slidably connected to an inclined plate, one side of the inclined plate is connected to a moving rod, the sleeve plate is connected to a fixed sleeve, the outer sleeve of the moving rod is connected to a spring, and one end of the moving rod is connected to a fixed disk.
[0005] As a further solution of the utility model: bolts are arranged in the flange 1, and the flange 1 is connected to the flange 2 by the bolts.
[0006] As a further solution of the utility model: a connecting plate is connected to one side of the inclined plate, and the moving rod is slidably connected in the fixing sleeve.
[0007] As a further solution of the utility model: the fixed disk is connected to the fixed sleeve through a spring, and the inclined plate is overlapped on the inclined block.

[0009] As a further solution of the utility model: a U-shaped groove is provided on the side of the second flange, and the sealing ring is clamped in the U-shaped groove.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] 1. The cast iron valve which is easy to disassemble and assemble is provided with a cross block, an inclined block, an inclined plate, a moving rod and a spring. When the cross block on the side of flange one fits with the cross groove and applies a downward thrust thereto, the inclined block will contact the inclined plate when the cross block moves, and the inclined plate will drive the spring to deform when the thrust is applied. When flange one and flange two are completely fitted together, the inclined plate will be separated from the inclined block, and the inclined plate after reset will overlap the top of the inclined block. The cast iron valve can play a certain positioning role in the assembly of flange one and flange two through the cooperation between the inclined block, the inclined plate and the spring, and the cast iron valve does not need manual support during assembly, so as to avoid the phenomenon that the position of the cast iron valve is offset during assembly due to hand slippage, thereby reducing the subsequent operation process.
[0012] 2. The cast iron valve which is easy to disassemble and assemble is provided with a U-shaped groove and a sealing ring. When flange one and flange two are fitted together, the sealing ring on the side of flange one will contact the U-shaped groove, and the sealing ring will slide in the U-shaped groove when flange one moves. When flange one and flange two are fixed, the sealing ring will play a certain sealing role on flange two, thereby avoiding liquid leakage after flange one and flange two are connected.

[0019] like Figure 1-4As shown, the utility model provides a technical solution: a cast iron valve that is easy to disassemble and assemble, comprising a valve body 1, a valve core 2 is rotatably connected inside the valve body 1, a flange 1 3 is connected to one end of the valve body 1, a flange 2 4 is connected to one side of the flange 1 3, a pipe body 5 is connected to one side of the flange 2 4, a sleeve plate 7 is connected to the outside of the flange 2 4, a cross groove 8 is provided inside the flange 2 4, a cross block 9 is connected to one side of the flange 1 3, an inclined block 10 is connected to one side of the cross block 9, and an inclined plate 13 is slidably connected to the sleeve plate 7;
[0020] Bolts 6 are arranged in flange 1 3, and flange 1 3 is connected to flange 2 4 through bolts 6. By setting a sleeve plate 7, when flange 1 3 and flange 2 4 need to be separated during disassembly, a pulling force can be applied to the inclined plate 13, and the inclined plate 13 will slide in the sleeve plate 7, so that the sleeve plate 7 plays a certain guiding role in the movement of the inclined plate 13, thereby preventing the inclined plate 13 from falling off during movement;
[0021] The cross block 9 is slidably connected in the cross groove 8, the flange 1 3 is connected to the outside with a sealing ring 12, the side of the flange 2 4 is provided with a U-shaped groove 11, and the sealing ring 12 is clamped in the U-shaped groove 11. By setting the cross groove 8 and the cross block 9, when the flange 1 3 is connected with the flange 2 4, the cross block 9 on the side of the flange 1 3 will slide in the cross groove 8, so that the cross groove 8 and the cross block 9 play a certain limiting role in the movement of the flange 1 3, avoiding the collision between the flange 1 3 and the flange 2 4 when the flange 1 3 moves;
