The rear end of the valve handle adopts a screw, a counterweight cylinder and double nuts are arranged on the screw, and the position of the heavy hammer can be adjusted in multiple gears. The counterweight can be conveniently adjusted to the optimal position. The free end of the valve handle 3 is a section of screw rod, a counterweight cylinder 4 is sleeved on the screw rod, and locking nuts 5 are arranged on two sides of the counterweight cylinder 4. As shown in fig. 2.
As shown in fig. 4, the valve body 1 of the present embodiment is a rectangular cylinder, and the cross section of the valve body is square; the included angle between the blanking wall surface of the ash falling hopper in the valve body and the horizontal plane is more than or equal to 65 degrees.
As shown in figures 3 and 4, the present embodiment adopts the rectangular cylinder as the valve body of the flap-type cinder valve for the first time. The most different from the traditional turning plate type ash discharge valve is that the outer contour of the valve body is very simple and the outer contour of the valve body is a cuboid. The boss of the traditional turning plate type ash discharge valve mounting bearing seat is omitted. The horizontal section of the valve body is square, and the whole valve body is a rectangular cylinder. The valve body can be bent and formed, labor and materials are saved, welding seams of the valve body are fewer than those of a valve body formed by assembling and welding a plurality of plates, the valve body is simple and convenient to manufacture, and the sealing performance is good. The whole height is low, and the occupied space is small. The same as the traditional turning plate type ash discharge valve is that: the valve is pressed downwards to discharge by means of the self weight of the accumulated dust in the valve, and no power is consumed.
As shown in fig. 4 and 5, two ends of the valve rotating shaft 11 penetrate through the valve body 1, and two ends of the valve rotating shaft 11 outside the valve body 1 are sleeved with the self-lubricating bush 12 and the shaft sleeve 6 and are limited by the elastic collar 7 for the shaft. As shown in fig. 5, the sleeve 6 is a copper sleeve, and the self-lubricating bush 12 is a commercially available self-lubricating bush. An elastic retainer ring (GB 894-2017) for mounting a shaft on the rotating shaft is used for preventing the self-lubricating sleeve from falling off.
The simple and compact turning plate type ash discharge valve adopts the simple shaft sleeve to replace an outer spherical bearing with a square seat, and the shaft sleeves at two ends are fixed by a core rod during welding so as to ensure the coaxiality.
As shown in fig. 4 and 5, two position-limiting sleeves 9 are sleeved on the valve rotating shaft 11 inside the valve body 1 at intervals, and the two position-limiting sleeves 9 are located at two ends of the valve plate 2. Two stop collars 9 are mounted on the valve shaft 11 to prevent axial movement of the valve plate.
As shown in fig. 5, the end of the valve handle 3 is welded to the circumferential surface of one end of the valve shaft 11.
As shown in fig. 4, the connecting flanges 10 are arranged at the upper and lower end ports of the valve body. In the embodiment, the size of the connecting flange 10 at the upper and lower ports of the valve body 1 is consistent with that of the mounting hole, the lower end of the valve plate does not exceed the flange at the lower part of the valve body when the valve plate is completely opened, and the two ash discharge valves are stacked and can be combined into a double-layer ash discharge valve. As shown in fig. 6.
As shown in fig. 5 and 7, a step staggered seam L is formed between the connecting flange 10 and the valve body 1, and the connecting flange 10 and the cylinder body are connected by adopting the step staggered seam and are welded and fixed. The valve plates are connected by adopting stepped staggered joints, the welding is convenient, and the workload of polishing the welding joints after welding is greatly reduced.
As shown in fig. 2, 4 and 5, the valve plate 2 is located at the lower opening of the ash hopper in the valve body 1, the upper edge of the valve plate 2 is welded with a strip-shaped connecting plate 8, and the strip-shaped connecting plate 8 is detachably connected to the valve rotating shaft 11 through a screw.
As shown in FIG. 5, in the present embodiment, the height of the valve body 1 is smaller than that of the valve body of the commercial dust discharge valve. Since the valve plate 2 interferes with the ash falling hopper above the valve rotating shaft 11, the valve plate 2 interferes with the valve body 1 below the valve rotating shaft 11, and welding is not good. If the valve plate is arranged above or below the rotating shaft, the height of the valve body is increased. Therefore, in this embodiment, the connection between the valve plate 2 and the valve shaft 11 is that the center line of the valve plate passes through the center of the shaft, and the valve plate is welded to have an operation space.
The working process of the embodiment:
as shown in fig. 1, the single-layer flap type cindervalve is a simple mechanical cindervalve. The valve plate of the single-layer panel turnover type dust unloading valve is connected with a lever system and fixed on a valve rotating shaft, and a balance weight is arranged on a lever at the other end of the valve rotating shaft, so that the valve plate is tightly attached to the dust discharging port. When a certain amount of dust is accumulated on the valve plate, the valve plate (inclined plate) is pressed down, the dust is discharged, and then the valve plate (inclined plate) is reset by the action of a heavy hammer, so that the device is a periodic intermittent dust (dust) discharging device. The sealing performance of the ash discharging valve is ensured by the close contact between the valve plate and the ash discharging port and the ash column with a certain height. Because the single-turning-plate type ash discharge valve discharges ash intermittently and periodically, air leakage is easy to occur when the valve is opened to discharge ash.
As shown in FIG. 6, two single-layer flap type ash valves are stacked to form a double-layer flap type ash valve. The structure of the double-layer turning plate type ash unloading valve is different from that of a single-layer turning plate type ash unloading valve in that two turning plate structures (two valve plates) are arranged, each turning plate is formed by connecting a valve plate with a lever system and is fixed on a valve rotating shaft, and a balance weight is arranged on a lever at the other end of the valve rotating shaft to enable the valve plate to be tightly attached to an ash discharging opening. Because the valve is provided with two layers of valve plates, when a certain amount of dust is accumulated on the first layer of valve plate, the valve plate is pressed down, and when the dust is discharged, the second layer of inclined plate still clings to the dust discharge port, so that air leakage is prevented. When the first layer inclined plate is reset by the action of the heavy hammer, and a certain amount of dust is accumulated on the second layer valve plate, the valve plate is pressed down, the dust is discharged, and then the first layer inclined plate is reset by the action of the heavy hammer. The device is also a periodical intermittent ash discharge device, the tightness is ensured by the close contact between a valve plate and an ash discharge port and an ash column with a certain height, but the air leakage rate is much less than that of a single-layer flap type ash discharge valve due to the double-layer flap.
The double-layer panel turnover type ash discharge valve mainly utilizes the switches of the upper valve plate and the lower valve plate at different time to ensure that one layer of valve plate is always in a closed and isolated state in the middle of the equipment to prevent air channeling.
Above embodiment only is for explaining the utility model discloses a technical thought can not be injectd with this the utility model discloses a protection scope, all according to the utility model provides a technical thought, any change of doing on technical scheme basis all falls into the utility model discloses within the protection scope.
