Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
In the figures 1-3, the device comprises a shell 1, an air inlet 2, a partition plate 3, a vertical opening partition plate 3-1, an upper vent 3-11, a lower vent 3-12, a horizontal opening partition plate 3-2, a left vent 3-21, a right vent 3-22, an exhaust port 4, an upper cover plate 5, a lower cover plate 6, a valve rod 7, a stuffing box 8 and the like.
As shown in fig. 1, the utility model relates to a high temperature valve packing box cooling structure, including valve rod 7, the valve plate is connected to 7 one side peripheries of valve rod, and the opposite side periphery sets up packing box 8, is equipped with casing 1 between valve plate and the packing box 8, and the 8 peripheries of packing box are located to 1 cover of casing, and casing 1 holds to open at nearly packing box has air inlet 2, holds to open at nearly valve plate has gas vent 4. A plurality of partition boards 3 are arranged in the shell 1.
The partition plate 3 is formed by arranging a vertical opening partition plate 3-1 and a horizontal opening partition plate 3-2 at intervals, as shown in figure 2, the vertical opening partition plate 3-1 is provided with an upper vent 3-11 and a lower vent 3-12 in the vertical direction, and as shown in figure 3, the horizontal opening partition plate 3-2 is provided with a left vent 3-21 and a right vent 3-22 in the horizontal direction.
The upper cover plate 5 and the lower cover plate 6 are respectively arranged at the upper end and the lower end of the shell 1.
The working process of the utility model is as follows:
compressed air is introduced into an air inlet 2 at the upper part of a shell 1, after the compressed air enters the shell 1, the compressed air is blocked by a partition plate 3, and after the space formed by the shell 1 and a straight opening partition plate 3-1 circulates, the compressed air enters the space between the vertical opening partition plate 3-1 and a horizontal opening partition plate 3-2 through an upper air vent 3-11 and a lower air vent 3-12 of the vertical opening partition plate 3-1, because notches on the vertical opening partition plate 3-1 and the horizontal opening partition plate 3-2 are arranged in a crossed mode, the compressed air must circulate the whole space and then enters the next space, and after multiple cycles, the compressed air is discharged from a high-temperature valve packing cooling structure through an air outlet 4. The compressed air circulates in the space formed by the shell 1 and the partition plate 3, the temperature outside the stuffing box is reduced, the temperature of the valve stuffing box is reduced, the function of protecting the stuffing is achieved, and the service life of the valve is prolonged.
The utility model discloses can reduce the temperature of valve packing box effectively, reach the effect of protection packing, prolong the whole live time of valve.
