Abstract
The utility model relates to the technical field of valves and discloses a novel ventilation pneumatic cut-off valve bank. The valve bank comprises an air inlet pipe, an air outlet pipe, an air inlet box, a disc valve, and an air outlet box. The air inlet pipe is communicated with the air inlet box. The air inlet box is communicated with the air outlet box. The air outlet box is communicated with the air outlet pipe. The disc valve is a cylinder-type disc valve which is mounted on the air inlet box and communicated with an inner cavity of the air inlet box and an inner cavity of the air outlet box. The opening or closing of the cylinder-type disc valve is used for allowing or blocking air ventilation between the air inlet pipe and the air outlet pipe. According to the utility model, by virtue of arranging the air inlet box and air outlet box having the air inlet pipe and air outlet pipe and arranging the disc valve having an cylinder, on one hand, the area of the cross section of the pneumatic cut-off valve bank does not need to be identical to that of the cross section of a pipeline of a ventilation de-dusting system in the connection place; and on the other hand, the novel ventilation pneumatic cut-off valve bank is advantaged by small on-off operation space and high modularization degree.

Background technique
Ventilation cut-off valve is that the air-flow extensively using on ventilating and purifying air system pipeline cuts off and locking closure, for example: in the situations such as the gas locking of ventilating and purifying air system pipeline, fault cut-out, energy-conservation adjusting, on-bne repair, all need to use ventilation cut-off valve to carry out air-flow cut-out and locking.
At present, conventional ventilation cut-off valve divides by control mode: have manual, pneumatic, electronic and electric liquid mode; Divide by valve plate pattern: the pattern that has butterfly valve, flashboard method, glasses valve, blank-plate valve (or blind plate).But there is following problem in above all valve classes: 1, cut off air-flow cross section need with is connected front and back wind dust pelletizing system pipeline uniform section; 2, keying operating space is larger; 3, for the valve class of super-section, cost and the difficulty of manufacture, transportation, assembly manipulation, maintenance are larger.Therefore, a kind of novel ventilated pneumatic cut-off valve group with new structure of necessary design, to overcome described defect of the prior art.
Model utility content
The purpose of this utility model be in prior art, exist pneumatic cut-off valve cross section need be connected before and after ventilating and purifying air system pipeline uniform section, to open and close operating space large and because the valve class of super-section is in the cost of manufacture, transportation, assembly manipulation, maintenance and the larger problem of difficulty, and a kind of novel ventilated pneumatic cut-off valve group is provided.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of novel ventilated pneumatic cut-off valve group, comprise air intake pipe, air outlet tube, inlet box, mushroom valve and air outlet box, described air intake pipe is communicated with inlet box, described inlet box is communicated with air outlet box, described air outlet box is communicated with air outlet tube, described mushroom valve is cylinder type mushroom valve, described cylinder type mushroom valve is arranged on inlet box and is communicated with the inner chamber of inlet box and the inner chamber of air outlet box, and the unlatching of this cylinder type mushroom valve or close for being communicated with or cutting off the ventilation between described air intake pipe and air outlet tube.
According to a preferred embodiment of the present utility model: described inlet box is arranged on the lower end of air outlet box, and the air flue of described inlet box and a right-angled corner of described air outlet box composition.
According to a preferred embodiment of the present utility model: described mushroom valve is straight-through type mushroom valve.
According to a preferred embodiment of the present utility model: the quantity of described air intake pipe is for being at least one, and the quantity of described mushroom valve is at least one.
According to a preferred embodiment of the present utility model: the quantity of described air intake pipe is two, and the quantity of described mushroom valve is six.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by being provided with inlet box and the air outlet box of air intake pipe and air outlet tube, and be provided with the mushroom valve with cylinder, on the one hand, pneumatic cut-off valve cross section without be connected before and after ventilating and purifying air system pipeline section homalographic, on the other hand, have advantages of that the operating space of keying is less, the degree of modularity is high.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Consult shown in Fig. 1 and Fig. 2, the utility model provides a kind of novel ventilated pneumatic cut-off valve group, comprise air intake pipe 1, air outlet tube 2, inlet box 3, mushroom valve 4 and air outlet box 5, wherein, described air intake pipe 1 is communicated with inlet box 3, described inlet box 3 is communicated with air outlet box 5, described air outlet box 5 is communicated with air outlet tube 2, described mushroom valve 4 is cylinder type mushroom valve, described cylinder type mushroom valve is arranged on inlet box 3 and is communicated with the inner chamber of inlet box 3 and the inner chamber of air outlet box 5, and the unlatching of this cylinder type mushroom valve or close for being communicated with or cutting off the ventilation between described air intake pipe 1 and air outlet tube 2.
In the utility model, inlet box 3 is specifically arranged on the lower end of air outlet box 5, and inlet box 3 and described air outlet box 5 form the air flue of a right-angled corner (90 °), can so that air intake pipe 1 with the axis of air outlet tube 2 not on same bar straight line.
In the utility model, described mushroom valve 4 is straight-through type mushroom valve.
In the utility model, the quantity of described air intake pipe 1 is for being at least one, and the quantity of described mushroom valve 4 is at least one.It is two that the present embodiment is selected the quantity of air intake pipe 1, and the quantity of mushroom valve 4 is six.
