Fig. 1 is the structure chart of balanced type pneumatic repid cut-off valve provided in an embodiment of the present invention.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Fig. 1 shows the structure of balanced type pneumatic repid cut-off valve provided in an embodiment of the present invention, for convenience of description only
It shows and the relevant part of the embodiment of the present invention.
As shown in Figure 1, provided in this embodiment includes valve body 1,1 upper end opening of the valve body is inserted with valve deck 2, the valve deck
2 are bolted with the valve body 1, the down-set circle locating ring 11 in 2 bottom of the valve deck, and 2 top of the valve deck is also solid
Surely there is a T-block 3,3 top of the T-block is further fixed on cylinder 4, and the cylinder 4 includes upper cover 41 and lower cover 42, between upper and lower covers
For cylinder body 43, be provided with piston 44 in the cylinder body 43, the pneumatic rapid cut-off valve further includes upper axis 5 and lower axle 6, it is described on
Axis 5 is inserted into from upper tops inside cylinder 4, and the lower axle 6 is fixed with 5 bottom of upper axis, then sequentially passes through lower cover 42, T-type
Block 3, valve deck 2 simultaneously stretch into inside valve body 1, and the piston 44 is fixed on 6 top of lower axle, and 6 bottom of the lower axle is fixed with flap 71,
71 bottom of the flap is further fixed on gland 72, and gasket 73, the flap are additionally provided between the gland 72 and flap 71
71 set up a circle guide ring 74, and the guide ring 74 is matched with the locating ring 11.
Stop valve of the present invention is mainly made of valve body and cylinder two parts, and when work, air source enters cylinder from cylinder upper cover
Interior, piston driving upper and lower axle and flap move down, and gasket is sealed with the mouth of a river in valve body, and valve is closed at this time；From cylinder
Lower cover injects air source, or from upper cover air-breathing, piston driving upper and lower axle and flap move up, gasket and the mouth of a river in valve body
It detaches, valve is opened at this time.In order to ensure leakproofness, setting sealing element is also needed in necessary place.Specifically, the lower axle with
Valve deck, lower cover, piston contact site and the upper axis and the contact site and piston and cylinder body of upper cover between, positioning
Sealing element is respectively provided between ring and guide ring.Guide ring described here is matched with the locating ring, refers to guide ring and positioning
It is sealed between ring, and guide ring can vertically be moved up and down exactly along locating ring inner wall or outer wall, moisture substantially will not be from leading
To being penetrated into guide ring between ring and locating ring (i.e. the upper space of flap).
In the present embodiment, cylinder is detached with valve body, and cylinder upper port is fixed by bolt and valve deck, and lower axle is inserted into from valve deck
To valve inner, the only possible path for occurring leaking of steam in valve body is that may be present micro- between valve deck and lower axle
Seam.And cylinder further decreases the possibility that the steam in valve body penetrates into cylinder, reduces string water probability, ensure far from valve body
The service life of stop valve.In addition, even if string water phenomenon occurs in cylinder, it can directly remove cylinder and repair, it is very convenient,
Even only need to remove upper cover can also complete to repair, and without dismantling valve body when due to repair, ensure that valve body overall structure
Stability, avoid repeatedly dismantling valve body and reducing the air-tightness of valve inner structure.
In this structure, the T-block 3 as between valve body 1 and cylinder 4 connection and isolated part, cylinder 4 it is not direct with
Valve deck is fixed, and the spacing of the two is increased, and reduces string water possibility.It is further used as a kind of preferred embodiment, the lower cover 42 and T-type
It is spaced a distance between block 3, and is fixed by fixing nut 31, several positioning are set between the lower cover 42 and T-block 3 and are protected
Sheath 32, the fixing nut 31 pass through the T-block 3, positioning protective sleeve 32 to be screwed into the lower cover 42 and fix, and described
Part of the lower axle 6 between lower cover 42 and T-block 3 is also installed with positioning protective sleeve.On the one hand the positioning protective sleeve is used as under
Support between lid and T-block, and fixing nut and lower axle is also protected not to be corroded by the external world.Even if simultaneously from valve deck and lower axle
Between slit exudation come steam, can also be distributed from T-block and the gap of lower between centers into air.Therefore in this structure due to
There are airspaces between T-block and lower cover of air cylinder, completely will not be into even if having can only distribute if steam exudation into air
Enter in cylinder, to completely avoid string water possibility.
It is detachable between the upper cover, cylinder body, lower cover, it is fixed as one by stud, between upper and lower covers and cylinder body,
It also is provided with sealing ring, avoids gas leakage.Cylinder detachable structure, is easy to install and maintain.In addition, 6 top of the lower axle is screwed with tightly
Gu nut 51 fixes the piston 44 by the fastening nut 51.The upper axis 5 is screwed with lower axle 6 to be connect, repair
When, axis can be backed out, cylinder is dismantled, unloads lower piston, directly to cylinder interior through row maintenance of clean-up, and body portion is as one
A entirety, without dismantling.
In addition, 5 top of the upper axis is further fixed on touch panel 8,41 top of the upper cover is also equipped with holder 9, the holder 9
On be provided with sensor 91.The sensor is for incuding the touch panel.During piston moves up and down, touching at the top of upper axis
Plate can also move up and down, and pass through the displacement distance of sensor sensing touch panel, you can realize switch control and the aperture of stop valve
Control.
In order to avoid stemming moisture accumulation, the sealing element between the lower axle and valve deck haves three layers, and 2 top of the valve deck is upward convex
A cylindrical structure is played, is equipped with perforative osculum 21 from the cylindrical structure side wall to location mid-shaft, the osculum 31 passes through 3
Layer sealing element in top layer sealing element and be connected to the lower axle outer wall.Trace Water Vapor is oozed out upwards along lower axle outer wall, then
It is discharged from the osculum, further avoids cylinder string regimen condition.Stop valve of the present invention is controlled and is driven, valve using air source
Built-in balance system, sealed reliable, using two-position-five-way solenoid valve energy remote control, valve can be at normally opened or normally off.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
