Abstract
The utility model discloses a control valve used for dust removing equipment, and particularly relates to a plugboard valve. The plugboard valve comprises a valve body, wherein the valve body is divided into an upper valve body and a lower valve body. A valve plate is arranged in the middle of a position between the upper valve body and the lower valve body. Valve cavities are arranged on the inner portion inside the upper valve body and the lower valve body. A sealed cavity is respectively arranged on each side of the valve cavity, wherein a valve plate cavity is arranged on the outer side of the sealed cavity. The valve plate is provided with a dust passing hole. More than one layer of sealing rings is arranged inside the sealed cavity. One end of the valve plate extends out to the outside of the valve body. The plugboard valve increases a contact area between the valve plate and the valve body, improves structural strength of the valve plate, and greatly improves capacity of bearing negative pressure of the plugboard valve. And at the same time, by adopting of multilayer sealing rings, sealing performance of the whole valve is improved and service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of control valve for dusting apparatus, especially a kind of push-pull valve.
Background technique
In the industry production processes such as metallurgy, mine, building materials, grain, chemical industry, tend to produce a large amount of dust under many process conditions at present, in order to reduce the impact on surrounding enviroment, supporting dedusting (dust suction) system all can be installed by above-mentioned enterprise.Simultaneously when these dedustings (dust suction) system works, oversize or the bye-pass of the pipeline that connects for fear of dedusting (dust suction) causes the low or dedusting main frame overload of negative pressure of system too much easily, can between main line and bye-pass, push-pull valve be installed, it is as the switch of the bye-pass in timely switch operating zone and inoperative zone, thereby guarantee system stable operation, reduce the waste of the energy and the loss of equipment.But existing push-pull valve, it is low in use to bear negative pressure, and sealing is relatively poor, and working life is shorter.
The model utility content
The utility model purpose is to provide a kind of push-pull valve, and it has changed the mounting type of valve plate for defects, has improved it and has born the ability of negative pressure.
The purpose of this utility model realizes by following structure, it comprises: valve body, valve body is divided into upper valve body and lower valve body, is provided with valve plate in the middle of described upper valve body and the lower valve body, and the middle part is valve pocket in upper valve body and the lower valve body, the valve pocket both sides respectively be provided with a Seal cage, the outside of one of them Seal cage is the valve plate chamber, valve plate was provided with the dirt hole, was provided with the seal ring more than 1 layer in the Seal cage, and an end of valve plate stretches out outside the valve body.
Described seal ring is preferably 2 layers, and 1 layer is rubber seal, and another layer is teflin ring.
Described upper valve body and lower valve body are connected in dedusting or the dust suction branch pipe(tube).
Described valve plate stretches out the outer end connecting drive device of valve body.
Described drive unit is cylinder, and cylinder connects source of compressed air.
Described drive unit is oil cylinder or motor.
The utility model adopts the valve plate that is installed between upper and lower valve body, and valve plate is slided between valve body, at valve plate the dirt hole is set simultaneously, has increased the area of contact of valve plate and valve body, has improved the structural strength of valve plate, has greatly improved it and has born the ability of negative pressure.By adopting multi-layer sealed circle, improve the sealing of whole valve simultaneously, increased the working life of valve.
Description of drawings
Fig. 1 is the structural drawing of mode of execution closed condition of the present utility model, and Fig. 2 is the structural drawing of mode of execution opening state of the present utility model.
Embodiment
The utility model comprises as depicted in figs. 1 and 2: valve body, valve body is divided into upper valve body 1 and lower valve body 2, be provided with valve plate 3 in the middle of described upper valve body 1 and the lower valve body 2, and the middle part is valve pocket 7 in upper valve body and the lower valve body, the valve pocket both sides respectively be provided with a Seal cage 8, the outside of one of them Seal cage is valve plate chamber 9, and valve plate was provided with the dirt hole.Be provided with 2 layers of seal ring in the Seal cage, 1 layer is rubber seal 4, rubber seal is used for regulating the leakproofness that seals between valve plate and valve body, further improve sealing effect, another layer is teflin ring 5, teflin ring is used in the sealing between valve body and valve plate, and teflin ring is with the selflubricating ability, Effective Raise the smoothness of valve plate motion.One end of valve plate stretches out outside the valve body, and valve plate stretches out the outer end connecting drive device 6 of valve body.Aforementioned drive unit has adopted cylinder, and the push rod that is about to cylinder connects valve plate, utilizes the fore and aft motion of cylinder push-rod to be used for the motion of drive valve plate in valve pocket and valve plate chamber, and then realizes the keying of valve.Need in use upper valve body 1 and lower valve body 2 are connected respectively in dedusting (or dust suction) branch pipe(tube), and cylinder is connected the source of compressed air that control valve is installed, thereby come the operation of accessory drive by adjusting control valve.
As the other alternate embodiment of the utility model, drive unit also can adopt in the aforementioned embodiments: oil cylinder or motor, and the structure of other parts of valve is identical with above-mentioned embodiment.
The utility model is extracted out from the valve plate chamber by the motion drive valve plate of drive unit when opening, and dust passes through valve pocket through the dirt hole.And when the utility model is closed, by the motion drive valve plate of drive unit it is sent back in the valve plate chamber, the interior formation of valve pocket is opened circuit make the valve cut-off.
