Technical Field

[0001] The utility model belongs to the technical field of valve seat production, in particular to a double-temperature zone heating furnace for valve seat production. Background Technique

[0002] A valve seat is a detachable surface component inside a valve, used to support the fully closed position of the valve core and form a sealing pair. Generally, the diameter of the valve seat is the maximum flow diameter of the valve. For example, the valve seat materials of butterfly valves are very extensive, and various rubber, plastic, and metal materials can be used as valve seat materials. The main function of a heating furnace is to heat materials or workpieces to the temperature required for rolling or forging.

[0003] During the production process of valve seats, a heating furnace is needed to heat the valve seats to an appropriate temperature. However, in the existing technology, most heating furnaces usually only have one temperature zone. This leads to the need to continuously adjust the temperature of the heating furnace when heating valve seats processed in different stages, so that the valve seats can adapt to the appropriate temperature for different stages of processing. This not only makes the operation process more troublesome, increases the workload of the staff, but also reduces the production efficiency of valve seats. Content of the Utility Model

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0013] For the double-temperature zone heating furnace for valve seat production, by arranging the isolation plate and the adjusting component, during use, first, according to the range of the valve seat to be heated in the temperature zone as required, move the isolation plate, so that the isolation plate moves in the furnace body, the adjusting block slides in the adjusting groove, and the movable mesh moves on the fixed mesh until the isolation plate moves to a suitable position. Then, place the valve seat on the movable mesh and the fixed mesh, cover the furnace cover through the cylinder, and then heat the double-temperature zone in the furnace body to a suitable temperature through the heating pipes in the furnace body. Compared with the prior art, the structure of the present utility model is simple and the design is reasonable. It can not only heat the valve seat at different temperatures, but also adjust the range of the temperature zone, and has strong applicability.

[0014] The double-temperature zone heating furnace for valve seat production, by setting a fixing component, when adjusting the position of the isolation plate, rotates the rotating column through the sliding component, so that the spring is no longer stressed and begins to stretch, causing the movable sleeve to slide upward in the movable groove, enabling the transmission rod to drive the rotating column to move upward through the rotating component, making the fixing block slide upward in the receiving groove until the spring is in a non-stressed state. At this time, the fixing block disengages from the fixing slot, and then the position of the isolation plate can be adjusted by moving it.

[0015] The double-temperature zone heating furnace for valve seat production, by setting a sliding groove and a sliding block, and using the sliding block to be movably matched with the sliding groove, sets the sliding groove as an L-shaped structure. By rotating the rotating column, the rotating column rotates in the movable groove, causing the sliding block to slide in the horizontal groove of the sliding groove until the sliding block slides to the intersection of the horizontal groove and the vertical groove of the sliding groove, so that the position of the rotating column in the movable groove is no longer fixed.

[0016] The double-temperature zone heating furnace for valve seat production, by setting a rotating groove and a rotating block, and using the rotating block to be rotationally matched with the rotating groove, sets the rotating block as a T-shaped structure. When the rotating column rotates in the movable groove, it can prevent the rotating column from driving the transmission rod to rotate, thus facilitating the sliding block to slide into the horizontal groove of the sliding groove.
