Abstract
The utility model discloses a kind of pump lines, including tube body, the inner wall of the arrival end of the tube body is equipped with internal screw thread, outside is equipped with ring flange, the outlet end of the tube body is equipped with external screw thread, the radius of the tube body gradually becomes smaller, and wearing layer, the direction progressive additive that the wearing layer becomes smaller with the radius of tube body are attached on the inner wall of the tube body.Since the caliber of tube body is gradually become smaller by entrance to export direction, therefore the flow velocity of mixed mud can become faster in managing, when mixed mud sprays, a faster initial velocity can be obtained, therefore it can spray distant, the stroke for improving mixed mud delivery pipe avoids because mixed mud can not convey in place and suspension of works；Since flow velocity of the mixed mud in pump line can be accelerated, it is bigger to the friction of tube wall, it is equipped with wearing layer in the inside of the tube wall of tube body in order to improve the service life of pump line, and be getting faster for flow velocity, the thickness of wearing layer is more and more thicker, avoids scrapping because of back segment serious wear.
Description
Technical field
The utility model relates to concrete mixer equipment technical fields, more particularly to a kind of pump line.
Background technique
Concrete conveying system is important one of the component part of concrete mixer, it includes delivery pipe and its delivery pipe
Support member, concrete mud is transported to the predetermined area by delivery pipe of the concrete in concrete conveying system, to complete
Remote concrete casting or perfusion operation.
In the construction process, the power that sometimes will appear pump truck is inadequate, causes the pressure in pump line inadequate, can not will mix
Soil is sent to scheduled height, but is difficult to find more powerful pump truck again for the moment, necessarily affects the period of construction, improves
Construction cost.
Utility model content
The purpose of this utility model is to provide a kind of pump lines, are connected to the conveying pipe end of pump truck, are not changing pump truck
Under the premise of power, mixed mud can be made to spray farther.
The technical scheme adopted by the utility model is a kind of pump line, including tube body, the inner wall of the arrival end of the tube body
Equipped with internal screw thread, outside is equipped with the ring flange for connection, and the outlet end of the tube body is equipped with external screw thread, the radius of the tube body
Gradually become smaller by entrance to export direction, be attached with wearing layer on the inner wall of the tube body, the wearing layer with tube body radius
The direction progressive additive to become smaller.
It advanced optimizes, uniform intervals are equipped with several peep holes, the caliber company of the peep hole and tube body on the tube body
It is logical, the peep hole and tube body it is axially vertical, be fixedly connected with sealing bolt in the peep hole.
It advanced optimizes, the groove that the top of the peep hole is equipped with and the nut of sealing bolt cooperates.
It advanced optimizes, the bottom face of the sealing bolt and the inner wall of tube body are concordant.
It advanced optimizes, the bore of the entrance of the tube body and the relative aperture of outlet are 2:1-3:1.
The utility model has the beneficial effects that the caliber due to tube body gradually becomes smaller, the flow velocity for managing interior mixed mud can become
Fastly, when mixed mud sprays, a faster initial velocity can be obtained, therefore distant, raising mixed mud can be sprayed
The stroke of conveying avoids because mixed mud can not convey in place and suspension of works；
It is bigger to the friction of tube wall since flow velocity of the mixed mud in pump line can be accelerated, in order to improve the use of pump line
Service life is equipped with wearing layer in the inside of the tube wall of tube body, and is getting faster for flow velocity, and the thickness of wearing layer is more and more thicker, avoids
It is scrapped because of back segment serious wear.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model pump line.
Specific embodiment
Pump line as shown in Figure 1, including tube body 1, the inner wall of the arrival end of tube body 1 are equipped with internal screw thread, and outside is equipped with and is used for
The outlet end of the ring flange 2 of connection, tube body 1 is equipped with external screw thread, and the radius of tube body 1 gradually becomes smaller, is attached on the inner wall of tube body 1
Wearing layer 3, wearing layer 3 with the radius of tube body 1 become smaller by entrance to export direction progressive additive.
When occurring being pumped inadequate, mixed mud delivery pipe final section is laid down, the pump of alternative costs utility model
Pipe, tube body 1 are screwed onto a section delivery pipe, and are further fixed by ring flange 2.Since the caliber of tube body 1 gradually becomes smaller,
Therefore the flow velocity of the mixed mud in pipe can become faster, and when mixed mud sprays, can obtain a faster initial velocity, therefore can
With the distant of injection, the stroke of mixed mud delivery pipe is improved, is avoided because mixed mud can not convey in place and suspension of works.
It is bigger to the friction of tube wall since flow velocity of the mixed mud in tube body 1 can be accelerated, in order to improve making for tube body 1
It is equipped with wearing layer 3 on the tube wall of tube body 1 with the service life, and is getting faster for flow velocity, the thickness of wearing layer 3 is more and more thicker, keeps away
Exempt to scrap because of back segment serious wear.
Since caliber becomes smaller, the case where tube body 1 is easy to appear blocking, uniform intervals are equipped with several peep holes on tube body 1,
Peep hole 4 is connected to the caliber of tube body 1, and peep hole 4 is axially vertical with tube body 1, is fixedly connected with sealing bolt in peep hole 4
5。
When blocking, sealing bolt 5 is unscrewed, the situation in observation tube judges blocking position, blocks when finding
When position, it is inserted into dredging tool from corresponding peep hole 4, purge operation is rapidly completed.
In order to further increase the sealing effect of sealing bolt 5, peep hole 4 and sealing bolt 5 is avoided the feelings leaked occur
Condition, in the groove that the top of peep hole 4 is equipped with and the nut of sealing bolt 5 cooperates.Nut can be with when tightening sealing bolt 5
Further function as sealing function.
Further, the bottom face of sealing bolt 5 is tilted along the direction that the radius of tube body 1 becomes smaller, and bottom face and tube body 1
Inner wall it is concordant.When sealing bolt 5 is attached to, the bottom face of sealing bolt 5 is concordant with the inner wall of tube body 1, avoids mixed mud
The phenomenon that soil deposits at peep hole 4.
Further, the bore of the entrance of tube body 1 and the relative aperture of outlet are 2:1-3:1.
Certainly, the utility model is not limited to above embodiment, and those skilled in the art are without prejudice to originally
Equivalent deformation or replacement can be also made under the premise of utility model spirit, these equivalent variation or replacement are all contained in the application
In claim limited range.
