Description

Upper adapter

Technical field

The utility model belongs to field of mechanical technique, and in particular to a kind of upper adapter.

Background technology

Upper adapter is mainly used for connecting solenoid valve, and purging of the external pressure air for passage is controlled by solenoid valve, The pipeline of existing upper adapter is only common through type pipeline, and purging effect is poor.

The content of the invention

The purpose of this utility model is that there are the above problem for existing technology, it is proposed that a kind of simple in structure, practical Easily upper adapter.

The purpose of this utility model can be realized by following technical proposal：A kind of upper adapter, it is characterised in that including Supervisor and looped pipeline, offer the main channel axially through supervisor in supervisor, and looped pipeline is tilted and is fixedly arranged on supervisor, and on looped pipeline The subaisle that offers axially through looped pipeline and communicated with main channel, is evenly distributed with main channel and some helically arranges Main drainage plate, and cone mouth structure is formed the end of closing on the adjacent two main drainage plate at main channel outlet is close to each other, in pair Some secondary drainage plates helically arranged are evenly distributed with passage, and in the adjacent two secondary drainage plates for closing on subaisle exit End it is close to each other formed cone mouth structure.

In above-mentioned upper adapter, in main channel, entrance is provided with main connecting seat, is opened up on main connecting seat outer wall There is external screw thread, facing outside diameter of the supervisor one end with the extend radially outwardly main convex shoulder to be formed and main convex shoulder in main connecting seat is more than The outside diameter of supervisor.

In above-mentioned upper adapter, subaisle entrance is provided with secondary connecting seat, is opened up on secondary connecting seat outer wall There is external screw thread, facing outside diameter of the looped pipeline one end with the extend radially outwardly secondary convex shoulder to be formed and secondary convex shoulder in secondary connecting seat is more than The outside diameter of looped pipeline.

Compared with prior art, the utility model in the main channel of supervisor by setting main drainage plate, in the pair of looped pipeline Secondary drainage plate is set in passage, while close to each other formed in end for closing on adjacent two main drainage plate at main channel outlet is bored Mouth structure, the end for the adjacent two secondary drainage plates for closing on subaisle exit is close to each other to form cone mouth structure, when solenoid valve is pacified During loaded on main connecting seat and secondary connecting seat, purging of the external pressure air for passage is controlled by solenoid valve, and by draining Plate leads into the air to passage, and drainage plate helically arranges the air passed through in passage can produce conflux effect Fruit so that air can be faster by passage, so that purging effect is good.

Embodiment

It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.

As shown in Figure 1 to Figure 2, adapter includes supervisor 1 and looped pipeline 2 in sheet, is offered in supervisor 1 axially through supervisor 1 main channel 11, looped pipeline 2, which tilts, to be fixedly arranged on supervisor 1, and offer on looped pipeline 2 axially through looped pipeline 2 and with main channel 11 The subaisle 21 communicated, is evenly distributed with some main drainage plates 12 helically arranged in main channel 11, and main logical closing on The end of the adjacent two main drainage plate 12 in 11 exit of road is close to each other to form cone mouth structure 5, is uniformly distributed in subaisle 21 There are some secondary drainage plates 22 helically arranged, and in the end phase for the adjacent two secondary drainage plates 22 for closing on 21 exit of subaisle Mutually close to formation cone mouth structure 5.

Further, in main channel, 11 entrance is provided with main connecting seat 3, and outer spiral shell is offered on main 3 outer wall of connecting seat Line, faces outside diameter of 1 one end of supervisor with the extend radially outwardly main convex shoulder 31 to be formed and main convex shoulder 31 in main connecting seat 3 and is more than The outside diameter of supervisor 1.

Further, 21 entrance of subaisle is provided with secondary connecting seat 4, outer spiral shell is offered on secondary 4 outer wall of connecting seat Line, faces outside diameter of 2 one end of looped pipeline with the extend radially outwardly secondary convex shoulder 41 to be formed and secondary convex shoulder 41 in secondary connecting seat 4 and is more than The outside diameter of looped pipeline 2.

By setting main drainage plate 12 in the main channel 11 of supervisor 1, secondary drainage plate is set in the subaisle 21 of looped pipeline 2 22, while the end formation cone mouth structure 5 close to each other that the adjacent two main drainage plate 12 in 11 exit of main channel will be closed on, close on The end of the adjacent two secondary drainage plates 22 in 21 exit of subaisle is close to each other to form cone mouth structure 5, when solenoid valve is installed on master When on connecting seat 3 and secondary connecting seat 4, purging of the external pressure air for passage is controlled by solenoid valve, and by drainage plate Lai The air to passage is led into, drainage plate, which helically arranges the air passed through in passage, can produce conflux effect, make Obtaining air can be faster by passage, so that purging effect is good.

At the same time in the end for the adjacent two main drainage plate 12 for closing on 11 exit of main channel formation cone mouth structure close to each other 5, in the end formation cone mouth structure 5 close to each other for the adjacent two secondary drainage plates 22 for closing on 21 exit of subaisle, this makes to have leisure When gas is flowed out out of corresponding passage, the wind speed of its channel exit is most fast, particularly in 21 exit of subaisle, is led to due to secondary The outlet of road 21 is communicated with main channel 11, therefore is entered to from the wind that 21 exit of subaisle is flowed out into after acceleration in main channel 11, The purging effect in main channel 11 can further be improved.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
