Abstract
The utility model relates to an arc valve, concretely relates to an eccentric arc valve mounted below a material bin or in the middle of a transmission pipeline capable of controlling the powder solidmaterial. The arc valve comprises a valve body, a driving device mounted at the side of the valve, a connection rod connected on the driving device, wherein another end of the connection rod is connected with a valve axle hinged on the top of a valve plate and an inner box in ladder-shaped structure is set in the valve and a sealing sleeve is sleeved on the valve axle and an end cover bearing ismounted on the end. The inner box of the valve uses the ladder-shaped structure and a feeding inlet and a discharging outlet are at eccentric state and the impact of the dropping material on the valveplate is reduced and the valve work flexibility and stability is ensured and the material is laid off smoothly and the sealing device and the end cover bearing reduce the friction between the parts and the service life of the valve plate and the valve is prolonged.
Description
Technical field
The utility model relates to a kind of arc valve, in the middle of specifically a kind of bottom or conveyance conduit that is installed in feed bin, is used for controlling the eccentric arc valve of divided solid materials.
Background technique
Arc valve is applied to building materials, metallurgy, electric power, petrochemical industry, light industry etc., is installed in the middle of the bottom or conveyance conduit of feed bin, is used for controlling divided solid materials.Arc valve promotes connecting rod by driving mechanism makes the arc valve plate rotarily open along the axle center, and material falls, treat blanking a period of time after, promote rocking bar again and make the arc valve sheet reset, block the material of whereabouts, thereby reach the purpose of control divided solid materials.When existing arc valve was worked, material directly impacted valve plate from the material entrance of valve body oblique upper, causes the wearing and tearing and the distortion of valve plate and valve shaft easily, directly influences the switch flexibility and the life-span of valve; The arc valve that also has adopts the end valve shaft to drive the rotation of arc valve plate, so the coaxality when the arc valve plate is installed is not easy to guarantee that it is not steady easily to be subjected to material to impact back valve plate rotation.If directly rotate single employing sealing back, valve shaft two ends, the frequent friction-produced of valve shaft and axle sleeve is worn and torn, and directly influences the switch flexibility and the life-span of valve.
The model utility content
The utility model is at deficiency of the prior art, provides a kind of simple in structure, convenient durable eccentric arc valve.
Realize that the technological scheme that above-mentioned purpose adopts is: a kind of eccentric arc valve, comprise valve body, be installed in the drive unit of valve body sidepiece, be connected with connecting rod on this drive unit, the hinged valve shaft in the connecting rod the other end and valve plate top is connected, described valve inner is provided with the internal box of stepped structure, is set with stuffing box gland on the described valve shaft, and the end is equipped with the end cap bearing.
Compared with prior art, the utility model is because the valve body internal box adopts step structure, material entrance and discharge port are in eccentric state, when having alleviated material and having fallen to the impact of valve plate, can guarantee valve body operation flexibility and stability, blanking is smooth and easy, and seal arrangement and end cap bearing have reduced the friction between parts, prolongs the working life of valve plate and valve body.

Fig. 3 is the structural representation of internal box.
Fig. 4 is the structural representation of sealing configuration and end cap bearing.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing, in the present embodiment, this eccentric arc valve, its drive unit 1 is installed in a side of valve body 6, be hinged with connecting rod 2 with pin or other links on this drive unit 1, the hinged valve shaft 4 in the other end of connecting rod 2 and valve plate 5 tops is hinged, be set with stuffing box gland 11 on the valve shaft 4, its end is equipped with end cap bearing 3, the inside of valve body 6 is provided with the internal box 7 of stepped structure, the material entrance 8 of this internal box 7 overlaps with valve body 1, and its discharge port 9 is provided with several angle with plumb line, and because the influence of step structure, make and have Horizontal displacement between discharge port 9 and the material entrance 8, reach eccentric effect, discharge port 9 ports are equipped with the valve plate 5 of arc, and this valve plate 5 is lifted on the two ends of valve shaft 4.Internal box 7 is provided with abrasion-proof backing block 9 near the sidewall of discharge port 10.The internal box 7 of step structure also can be made the slope of wide-angle or the big step of one-level.
Principle of the present utility model is: in when work, do the to-and-fro motion of level by drive unit 1, promote the swing of connecting rod 2 at several angle, drive valve shaft 4 and rotate, move along the axle center rotating open-close thereby drive valve plate 5, reach the purpose of control mass flow.
Claims (2)
1, a kind of eccentric arc valve, comprise valve body, be installed in the drive unit of valve body sidepiece, be connected with connecting rod on this drive unit, the hinged valve shaft in the connecting rod the other end and valve plate top is connected, and it is characterized in that described valve inner is provided with the internal box of stepped structure, be set with stuffing box gland on the described valve shaft, the end is equipped with the end cap bearing.
2, eccentric arc valve according to claim 1 is characterized in that, the sidewall of described internal box is provided with abrasion-proof backing block.
