Abstract
The utility model relates to a balance weight type flat valve which comprises a left valve body, a right valve body, a valve plate, a seal ring, a loosening and clamping device, a plate device, a connecting base, a pull rod, a driving dual-turning direction lead screw pair and a driven dual-turning direction lead screw pair. A balance weight and a balance weight lever are additionally arranged on the valve plate, the centre-of-gravity of the valve plate is adjusted by the additionally arranged balance weight, and thus the driving moment of a flap plate is greatly reduced, the manufacturing cost of the flat valve device is saved, meanwhile, the operation of the valve plate is steady and the service life of the valve is long.
Description
Technical field
The utility model relates to a kind of counterweight type Flap valve, relate in particular to a kind of for gas pipe line, effectively cut off coal gas, realize the counterweight type Flap valve of valve zero leakage.
Background technique
Flap valve belongs to glasses valve, be called again blank-plate valve or quadrant valve in the industry, be mainly used on the gas pipe line of system for blast furnace ironmaking or pneumatic steelmaking system, coal gas is implemented to cut off reliably, it is a kind of key equipment of guaranteeing the coal gas zero leakage, be provided with through hole socket and blind plate seat on the valve plate, the driving mode such as common employing is manual, Electric actuator, oil hydraulic cylinder, cylinder realize the switching of valve plate through hole socket and blind plate seat, to realize circulation or the cut-off of medium in the valve.Owing to there is the disadvantage of valve plate position of centre of gravity substantial deviation valve plate rotating center on the valve plate project organization, cause when drive valve plate, need to arrange larger drive unit, so not only increase the manufacture cost of valve, also exist the valve plate running resistance greatly, not steadily, accident rate is high, working life is short problem.
The model utility content
The purpose of this utility model is exactly the problem that exists in order to solve above-mentioned prior art, and a kind of counterweight type Flap valve is provided, and its novel structure reduces cost, stable performance, long service life.
For achieving the above object, the utility model adopts as follows
Technological scheme:
A kind of counterweight type Flap valve, comprise left valve barrel and right valve barrel, between left valve barrel and right valve barrel, be provided with the valve plate that is formed by connecting plate one, through hole socket, blind plate seat, connecting plate two, it is characterized in that: the connecting plate one at described valve plate is installed with weight linear meter, and the other end of weight linear meter is provided with the adjustable counterweight in position.
After the utility model counterweight type Flap valve is innovated through project organization, its
Beneficial effectFor: 1. by the cheap counterweight of setup cost, adjust the position of centre of gravity of valve plate, reduced the manufacture cost of turnover panel drive unit; 2. by adjusting the position of centre of gravity of valve plate, when adopting cylinder, oil hydraulic cylinder or Electrohydraulic push rod device to drive, eliminated action and creeped and larger rotational noise, moved more steady.
The advantages such as the utility model counterweight type Flap valve has novel structure, reduces cost, operates steadily, long service life.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Such as Fig. 1, Fig. 2, shown in Figure 3, the utility model counterweight type Flap valve comprises left valve barrel 13 and right valve barrel 4, between left valve barrel 13 and right valve barrel 4, be provided with by connecting plate 1, through hole socket 15, blind plate seat 8, the valve plate that connecting plate 2 10 forms, left valve barrel 13 and right valve barrel 4 pass through three with the uniform double rotational directions lead screw pair (active of valve body center, two are driven) link together, the clamp device 1 that unclamps that is arranged on the whole front side of valve drives active double rotational directions lead screw pair 18 through drive sprocket 2, drive chain 3, driven double rotational directions lead screw pair 14 realizes unclamping of valve, clamp action, by connecting base 12 is set, pull bar 17 is guaranteed the fixing of connection between left valve barrel 13 and 4 liang of end flange of right valve barrel and relative position.Connecting plate 1 at described valve plate is equipped with weight linear meter 6, and weight linear meter 6 lower ends paste at connecting plate one 7 outer surfaces adopts welding manner and connecting plate 1 to fix, and is provided with the adjustable counterweight in position 5 in the upper end of weight linear meter 6.
As shown in Figure 1, the panel turnover device 11 that arranges on the valve drives connecting plate 2 10 and guarantees the rotation of valve plate centered by valve plate rotating center 16, the switching of blind plate seat 8 and through hole socket 15 on the realization valve plate, the seal ring 9 that blind plate seat 8 and through hole socket 15 arrange is respectively guaranteed the sealing after valve plate clamps; Panel turnover device 11 can be Electric actuator, also can be oil hydraulic cylinder, cylinder, electric pushrod device or Electrohydraulic push rod device, to realize the turnover panel action of valve plate.
As shown in Figure 3, be provided with weight linear meter 6 and counterweight 5 on the valve plate, its objective is in order to adjust the position of centre of gravity of valve plate, make the position of centre of gravity of valve plate after adjusting on the symmetrical center line of blind plate seat 8 and through hole socket 15, and as far as possible near valve plate rotating center 16, to reduce the driving moment of valve plate, make the valve plate operation more steady, longer service life.The mounting point that a plurality of attachment holes are used for regulating counterweight 5 can be set on the weight linear meter 6, to adjust counterweight 5 to the distance of valve plate rotating center 16, reach the best effect of adjusting.
