Description
Technical field
The utility model relates to equipment technical field of sealing technology, specifically refers to a kind of air cooling seal arrangement.
Background technique
On the pipeline of fluid, general needs arranges the piston valve for controlling fluid.Piston valve set on fluid circuit in the industries such as some petrochemical industry, light textile, metallurgy, electric power, chemical industry has certain corrosion resistance requirement.Existingly comprise valve body, valve rod, spool for the structure of piston valve in these industries, in valve body, be also provided with valve seat, valve seat is provided with the sealing surface corresponding with spool shape and position, overlaps the seal ring having graphite material to make in the outside of spool.Realize blocking pipeline inner fluid, described seal ring can closely be engaged on sealing surface set on valve seat.Although the seal ring that graphite material is made can adapt to the corrosion resistance requirement of some special industries, but when valve small guide vane is opened or close, pressure reduction on valve nearly all concentrates on the sealing surface on seal ring and valve seat, thus fluid washes away seriously to above-mentioned sealing surface, this very easily causes the damage of the seal ring be made up of graphite material merely, need often to change seal ring, thus bring trouble to the maintenance of pipeline.
Model utility content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of good sealing effect, and air cooling sealing removable mounting easy to use is put.
For achieving the above object, the utility model adopts following technological scheme: air cooling seal arrangement, comprises hollow cylinder body, piston valve, valve rod and air cooling tight connecting seat; Described cylinder body comprises upper and lower two-part, and top is divided into piston valve itinerary part, and bottom is divided into induction part; The sidewall of described cylinder body has the discharge port that be communicated with hollow with it, also there is the upper air-vent that be communicated with hollow with it and lower exhaust port; Wherein, discharge port and upper air-vent are positioned at the piston valve itinerary part of cylinder body, and lower exhaust port is positioned at the induction part of cylinder body; The top of described piston valve and valve rod is arranged on the hollow of cylinder body, and wherein, piston valve coordinates with inboard wall of cylinder block slidable sealing, and the top of valve rod is connected with piston valve, and valve rod drives piston valve to move up and down along inboard wall of cylinder block; Described air cooling tight connecting seat is arranged on the below of cylinder body, and air cooling tight connecting seat is hollow structure, and its hollow space is communicated with the hollow of cylinder body; Air cooling tight connecting seat has the suction tude of pressurized gas input.
As preferably, described lower exhaust port and lower exhaust port are respectively a pair coaxial through hole.
Relative to prior art, the utility model tool has the following advantages: the air cooling sealing removable mounting that the utility model provides is put, and structure is simple, feature easy to use.Pressurized gas enters the hollow space of air cooling tight connecting seat by suction tude, and then enter the hollow parts of cylinder body, because pressurized gas makes cylinder body hollow parts keep malleation, thus can by pressurized gas to the sealing gap between piston valve and cylinder body madial wall, gas can also play the effect of cooling cylinder body, valve rod and piston valve simultaneously, prevents its high temperature deformation from damaging.

Fig. 2 is another sectional view of air cooling seal arrangement.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In description of the present utility model, it will be appreciated that, orientation or the position relationship of the instruction such as term " top ", " end ", " on ", D score, interior ", " outward " they be based on orientation shown in the drawings or position relationship; be only the utility model and simplified characterization for convenience of description; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1 and Fig. 2, a kind of air cooling seal arrangement, comprises hollow cylinder body 10, piston valve 20, valve rod 30 and air cooling tight connecting seat 40.
Described cylinder body 10 comprises upper and lower two-part, and top is divided into piston valve 20 itinerary part, and bottom is divided into induction part.
The sidewall of described cylinder body 10 has the discharge port 12 that be communicated with hollow with it, also there is the upper air-vent 13 that be communicated with hollow with it and lower exhaust port 14; Wherein, discharge port 12 and upper air-vent 13 are positioned at piston valve 20 itinerary part of cylinder body 10, and lower exhaust port 14 is positioned at the induction part of cylinder body 10; Lower exhaust port 14 and lower exhaust port 14 are respectively a pair coaxial through hole.
The top of described piston valve 20 and valve rod 30 is arranged on the hollow of cylinder body 10, and wherein, piston valve 20 coordinates with cylinder body 10 inwall slidable sealing, and the top of valve rod 30 is connected with piston valve 20, and valve rod 30 drives piston valve 20 to move up and down along cylinder body 10 inwall.
Described air cooling tight connecting seat 40 is arranged on the below of cylinder body 10, and air cooling tight connecting seat 40 is hollow structure, and its hollow space is communicated with the hollow of cylinder body 10.
Air cooling tight connecting seat 40 has the suction tude 41 of pressurized gas input.
The using process of the air cooling seal arrangement that the utility model provides is as follows:
Material bin 11 is arranged on the top of cylinder body 10, and material bin 11 is communicated with the hollow parts of cylinder body 10, thus the material in material bin can enter the hollow parts of cylinder body.
The below of air cooling tight connecting seat 40 is provided with cylinder driver 50, and the bottom of valve rod 30 is connected with cylinder driver 50, and cylinder driver 50 actuate valve stem 30 moves up and down.Valve rod 30 drives piston valve 20 to slide up and down along the inwall of cylinder body 10.
When piston valve 20 is in the position of cylinder body 10 inner carrier valve 20 itinerary part the top, piston valve 20 material blocked in material mouth do not enter the body of rod hollow in, when piston valve 20 is in cylinder body 10 inner carrier valve 20 itinerary part position bottom, piston valve 20 is in the below of discharge port 12, and material is discharged from discharge port 12.
The sealing of piston valve is the hollow parts that the pressurized air passed into by the suction tude 41 on tight connecting seat 40 is full of in cylinder body, the while of with it, by upper air-vent and the exhaust of lower exhaust port, and make cylinder body hollow parts keep certain malleation, thus the gap blocked between piston valve 20 and cylinder body 10 inwall, the effect of cooling cylinder body 10, valve rod 30 and piston valve 20 can also be played simultaneously, prevent its high temperature deformation from damaging.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
