Abstract
The utility model relates to a combined dust collector comprising a valve cavity body 6, a ball core 5, a sealing ring 4, a joint 3, a ball core shaft 1, a handle 2, a dust collecting cover 7, etc. The utility model is characterized in that the valve cavity body 6 is separated from the joint 3; a loading inlet of the ball core 5 is a connecting opening between the joint 3 and the valve cavity body 6. The upper end of the valve cavity body 6 is provided with only a ball core shaft opening. As a result, the sealing ring 4 is tightly pressed by the joint 3, and the role of regulating sealing degree is played by the joint 3. Consequently, the utility model has the advantages of simple structure, simple and convenient installation and production technology, favorable sealing performance, etc.
Description
The utility model relates to a kind of combined type dust collector.
On the railway industry, the structure of former combined type dust collector is that the employing dust collector body is a monolithic construction, valve pocket is the garden bucket formula structure that opening makes progress, the ball core is packed into from the top of dust collector body, and ball core, seal ring and valve pocket are interference fit, are embedded in the bucket formula valve pocket of garden, and friction top is fixed by bolts to bucket formula valve pocket upper end, garden, this sealing structure poor performance, installation, complex manufacturing.
The purpose of this utility model provides a kind of installation, production technology is good, the combined type dust collector of good seal performance.
For achieving the above object, the utility model adopts following organization plan: dust collector body is divided into three parts, be that valve chamber is a part, joint is a part, dust collector hood is a part, and joint and valve chamber part is by being threaded, and a valve pocket top drop pass mandrel mouth, ball core loading port are a bite together with valve chamber and joint connection mouth, ball core and seal ring are packed into from joint and valve chamber connection mouth, compress seal ring by joint.
Because adopted the split of valve chamber and joint in the technique scheme, ball core loading port is the connection mouth of valve chamber and joint, and sealability can be regulated by joint, sealability is improved, installation and production technology are easy.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the cross-sectional view of combined type dust collector.
As shown in Figure 1, the combined type dust collector body is by joint 3, valve chamber 6, dust collector hood 7 three parts, and joint 3 and valve chamber 6 are by being threaded, dust collector hood 7 and valve chamber 6 are connected by bolt, ball mandrel 1 is connected with ball core 5 from top by ball mandrel mouth, and ball mandrel 1 is compressed by clamping nut, and handle 2 is connected with ball mandrel 1, during installation, first seal ring 4 pack earlier in valve pocket 8, refill goal core 5, after second seal ring 5 of packing into, screw in by joint 3 at last, compress seal ring 4.Like this, seal degree can be regulated by the tightness that joint 3 screws in, and like this, this practicality is installed very convenient, saves the strength, and production technology is also greatly easy.
