Detailed Description
As shown in figures 1-5, in the pressure-isolating sealing exhaust structure, the exhaust end of a stop valve 8 is communicated with an air inlet interface 3 through a U-shaped protection cavity 6, the air inlet interface 3 is communicated with an air cavity 5, a throttling and air-dispersing valve 1 is arranged at the end part of the air outlet of the air cavity 5, a vent hole 4 is arranged inside the throttling and air-dispersing valve 1, a plurality of exhaust holes 2 are arranged at the exhaust end of the throttling and air-dispersing valve 1, and the exhaust holes 2 are communicated with the air cavity 5 through the vent hole 4.
In a preferable scheme, the throttling air dispersing valve 1 is in threaded connection or clamped connection with the air cavity 5. When the air is not exhausted, the stop valve 8 is closed, and air is remained in the air cavity 5 and the U-shaped protection cavity 6 and is connected with the throttling air dispersing valve 1 at the tail end and the atmosphere. When external liquid enters the exhaust hole 2, the internal air can form a closed internal positive pressure cavity under the throttling action of the exhaust hole 2, and the blocking effect is achieved. The structure has no directivity, and all directions can play a role in plugging. The exhaust holes 2 are directly connected with the atmosphere, the number of the small holes is controlled, large air resistance cannot be generated, and exhaust is not affected. Even there is the stronger medium of infiltration type to get into, because 6 structures in U type protection chamber, also can form the liquid seal, guarantee that it can not direct contact stop valve 8, can effectively prevent the damage of material such as outside acid-base to the stop valve. The spraying device also has strong protective performance for the pressurized spraying, and due to the structure of the small holes of the exhaust holes 2, the external pressure cannot be converted into the power for the medium to enter the internal cavity, so that the sprayed medium is difficult to enter the cavity. Under normal installation conditions.
In the preferred scheme, a plurality of exhaust holes 2 are uniformly arranged at the end part of the throttling and air dispersing valve 1, and the exhaust holes 2 are arranged vertically or obliquely with the axis of the throttling and air dispersing valve 1. The air outlet of the structure is designed downwards or obliquely downwards, and external media are difficult to enter the interior due to the action of gravity.
The exhaust end of the throttling and air dispersing valve 1 adopts a structure of dispersing exhaust holes 2, so that the normal discharge of gas is ensured, and the blockage is not easy to occur. The exhaust hole 2 of the throttling and air dispersing valve 1 is a small hole with the diameter of 1.5mm, the small hole of the exhaust hole 2 is directly connected with the atmosphere, so that large air resistance cannot be generated, and different quantities of the small holes can be set according to flow requirements, so that the exhaust flow can be adjusted.
The air flue protection chamber 6 adopts a U-shaped design in the middle of the design, so that even if liquid media enter, liquid seal can be formed in the U-shaped protection chamber, the direct contact between the liquid media and the valve body is avoided, and then foreign matters are discharged through positive pressure exhaust. Because inside is the malleation chamber, material such as dust can only pile up externally because the restriction of structure is difficult to get into inside the cavity, and a small amount of entering dust accessible malleation is discharged effectively and is discharged.
In the preferred scheme, the end part of the throttling air dispersing valve 1 is also provided with a slag-proof cover 7, the slag-proof cover 7 is sleeved at the exhaust end of the throttling air dispersing valve 1, a plurality of openings are uniformly formed in the circumference of the slag-proof cover 7, and a slag-proof net 701 is arranged on each opening. The slag-proof cover 7 plays a role of preventing slag from entering the exhaust hole 2, thereby blocking the exhaust hole 2, the slag-proof net 701 plays a role of stopping slag,
in the preferred scheme, the exhaust end of the throttling air dispersing valve 1 is also provided with a locking part 9, and a locking groove 703 matched with the locking part 9 is arranged in the slag-proof cover 7. The locking portion 9 is engaged with the locking groove 703 or screwed. In the structure shown in fig. 4-5, the locking part 9 is in threaded connection with the locking groove 703, and the slag-proof cover 7 is in threaded connection with the exhaust end of the throttle valve 1.
Preferably, the slag-proof cover 7 is further provided with a tightening end 702 at the end. The clinch end 702 is used to clinch the slag guard 7.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims.
