Background technology
Pneumatic baffle valve plays an important role in vacuum pump set, in the high vacuum unit of especially 600 diffusion pumps, existing
The high vacuum units of 600 diffusion pumps be to be arranged as follows when in use, in the baffled valve in vacuum furnace body side, flapper valve air inlet
The outlet port of end connection vacuum furnace body exhaust port, flapper valve connects vacuum pumping pump, and vacuum pump is arranged in flapper valve lower end；By
The height of flapper valve is added to already exceed vacuum furnace body height in conventional vacuum pump, and its air inlet of existing flapper valve is circle
Shape, circular air inlet centre-height is also high, need to connect when vacuum drying oven and flapper valve being caused to be connected one section tilt upward lead
Flow tube could realize being connected for vacuum drying oven and flapper valve.In addition the exhaust outlet conductance of flapper valve is certain, and air inlet is arranged to circle
The position of round air inlet lower end both sides is caused to waste.
Utility model content
In view of the deficienciess of the prior art, the technical problem to be solved by the utility model is to provide a kind of rectangular air inlets
Mouth high conductance Pneumatic baffle valve, the air inlet centre-height of the flapper valve is low and air inlet conductance is big.
The utility model adopts the following technical scheme that complete：High conductance Pneumatic baffle valve, including valve body, on valve body
End is equipped with cylinder, it is characterised in that：The air inlet of valve body is arranged in valve body side, and the gas outlet of valve body is arranged under valve body
End, in valve body, the lower end of cylinder be connected with valve deck, the cylinder lower end passes through inverted T shaped gland and connects valve deck, it is described fall T
It is bolted between type gland and valve deck, there is cavity, the front end of the cylinder inside the interconnecting piece of inverted T shaped gland upper end
It fixes in the cavity；The valve deck is corresponding with the gas outlet of valve body, corresponding with valve body gas outlet on valve deck to set
It is equipped with ring type seal；The air inlet is rectangular air inlet.
As a preferred embodiment, the width of the rectangular air inlet is more than height；This width is more than the flat of height
The centre-height of rectangle is relatively low, reduces the when of being connected with vacuum drying oven after height and can accomplish be connected parallel with the gas outlet of vacuum drying oven
Form, not only save material and air operation distance shorten, increase vacuumize efficiency.
As another preferred embodiment, it is connected by seal box between the cylinder and the upper valve cover board of valve body upper end；
The seal box can be replaced sealing bearing.
The utility model has the beneficial effects that：The utility model Pneumatic baffle valve is more than the square of height using air scoop width
Shape air inlet；The centre-height that this width is more than the flat rectangle of height is relatively low, and reducing can when being connected with vacuum drying oven after height
By accomplish it is parallel with the gas outlet of vacuum drying oven it is connected in the form of, not only save material and air operation distance shorten, increase take out
Vacuum efficiency.In addition, rectangular air inlet, it can be bigger than level round air inlet open area, conductance also becomes larger, to
Promotion vacuumizes efficiency.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure, 1 is valve deck；2 be annular seal ring；3 be inverted T shaped gland, 4 be air inlet, 5 be spider, 6 be cylinder, 7 be
Seal box, 8 be valve body, 9 be gas outlet.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The technical issues of in order to keep the utility model solved, technical solution and advantageous effect are more clearly understood, below
In conjunction with specific embodiments, the utility model is further described.It should be appreciated that specific embodiment described herein is only
To explain the utility model, be not used to limit the utility model.
With reference to the accompanying drawings shown in 1, high conductance Pneumatic baffle valve, including valve body 8,8 upper end of valve body is equipped with cylinder 6, on valve body 8
End is equipped with spider 5, and the spider 5 is circular ring shape spider, and cylinder 6 is set to 5 upper end of the spider；The air inlet of valve body 8 is arranged
In 8 side of valve body, the gas outlet of valve body 8 is arranged in the lower end of valve body 8, in valve body 8, the lower end of cylinder 6 be connected with valve deck 1,
The cylinder lower end connects valve deck by inverted T shaped gland 3, is bolted between the inverted T shaped gland 3 and valve deck 1,
There is cavity, the front end of the cylinder 6 to fix in the cavity inside the interconnecting piece of 3 upper end of T-type gland；The valve deck 1 with
The gas outlet of valve body 8 is corresponding, corresponding with valve body gas outlet on valve deck 1 to be provided with ring type seal 2；The air inlet
Mouth is rectangular air inlet.
As a preferred embodiment, the width of the rectangular air inlet is more than height；This width is more than the flat of height
The centre-height of rectangle is relatively low, reduces the when of being connected with vacuum drying oven after height and can accomplish be connected parallel with the gas outlet of vacuum drying oven
Form, not only save material and air operation distance shorten, increase vacuumize efficiency.
As another preferred embodiment, pass through seal box phase between the cylinder 6 and the upper valve cover board of 8 upper end of valve body
Even；The seal box can be replaced sealing bearing.
The utility model has the beneficial effects that：The utility model Pneumatic baffle valve is more than the square of height using air scoop width
Shape air inlet；The centre-height that this width is more than the flat rectangle of height is relatively low, and reducing can when being connected with vacuum drying oven after height
By accomplish it is parallel with the gas outlet of vacuum drying oven it is connected in the form of, not only save material and air operation distance shorten, increase take out
Vacuum efficiency.In addition, rectangular air inlet, it can be bigger than level round air inlet open area, conductance also becomes larger, to
Promotion vacuumizes efficiency.The reason is that level its periphery edge space of circle air inlet all slatterns, and make
The space of edge can all be utilized upper, increase conductance by rectangular air inlet.
