Abstract
The utility model relates to a diesel engine air inlet connecting pipe which comprises an air inlet main pipe and an air inlet connecting pipe, wherein one end of the air inlet connecting pipe serves as an air inlet end, and one end of the air inlet main pipe serves as an air outlet end. The diesel engine air inlet connecting pipe is characterized in that the other end of the air inlet connecting pipe is connected with the other end of the air inlet main pipe through threads; the other end of the air inlet connecting pipe is matched with the other end of the air inlet main pipe in pipe diameter; the pipe diameter of the air inlet end of the air inlet connecting pipe is smaller than that of the other end of the air inlet connecting pipe, and the pipe diameter of the air outlet end of the air inlet main pipe is larger than that of the other end of the air inlet main pipe; external threads are arranged at the other end of the air inlet main pipe, and internal threads are arranged at the other end of the air inlet connecting pipe; a sealing rubber ring is sleeve on the joint of the air inlet main pipe and the air inlet connecting pipe; and an installation flange is installed at the air outlet end of the air inlet main pipe. According to the diesel engine air inlet connecting pipe, the appearance and inner quality are good, the shape and the structure of an existing air inlet connecting pipe are changed, and production in a high-pressure gorging process is convenient.
Description
Technical field
The utility model relates to a kind of air inlet tube, and especially a kind of diesel engine air inlet tube belongs to the diesel-engine equipment technical field.
Background technique
Engine aspirating system refers to air or mixed gas are imported the component aggregate of cylinder, and air inlet tube is a kind of connection moulding pipe for wherein.Engine aspirating system provides an intake resistance little for motor, the charging efficiency height, and inflammable mixture is even, the passage that enters engine cylinder-body that strength of vortex is big.
Existing air inlet tube generally uses gravity, low pressure, sand casting process manufacturing to obtain, and there is following defective in existing air inlet tube: the appearance quality of (1) air inlet tube is poor, and the error of blank dimension is big; (2) in long using process, sealing effect is undesirable, and throughput can not satisfy customer requirement, and online installation and engineering the seepage phenomenon often occurs in using; (3) existing air inlet tube is owing to the restriction of profile, and the mouth of pipe is little broad in the middle, and is curved shape, can not the demoulding when adopting squeeze casting technology to make.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of diesel engine air inlet tube is provided, and outward appearance is superior, favorable sealing property, more durable.
According to the technological scheme that the utility model provides, described diesel engine air inlet tube comprises the air inlet person in charge and air inlet tube, and an end of air inlet tube is inlet end, and the end that air inlet is responsible for is the outlet side; It is characterized in that: the other end that the other end of described air inlet tube and air inlet are responsible for is by being threaded.
The other end caliber that the other end of described air inlet tube and air inlet are responsible for matches.
The inlet end caliber of described air inlet tube is less than the caliber of the air inlet tube the other end, and the outlet side pipe path that air inlet is responsible for is responsible for the caliber of the other end greater than air inlet.
Establish outside thread at the other end that described air inlet is responsible for, establish internal thread at the other end of air inlet tube.
At the sheathed sealing rubber ring in the joint of the described air inlet person in charge and air inlet tube.
The outlet side of being responsible in described air inlet arranges the installation method.
The utlity model has following advantage: (1) diesel engine air inlet tube described in the utility model has higher appearance quality, and surface finishment can reach Ra3.2 ~ Ra6.3, and blank size precision is CT5 ~ 7 grade, the material structure densification, the intensity height, the manufacturing efficiency height is fit to produce in enormous quantities; (2) air inlet tube outward appearance described in the utility model, inherent quality are good; Change shape and the structure of present air inlet tube, be convenient to the production of squeeze casting technology.

Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 5: as described in the diesel engine air inlet tube comprise that air inlet is responsible for 1, air inlet tube 2, mounting flange 3 etc.
As Fig. 1～shown in Figure 5, the utility model comprises that air inlet is responsible for 1 and air inlet tube 2, and an end of air inlet tube 2 is inlet end, and it is the outlet side that an end of 1 is responsible in air inlet, is responsible for 1 outlet side in air inlet mounting flange 3 is set; The other end of described air inlet tube 2 and air inlet are responsible for 1 the other end by being threaded, and evenly smear the WD1001 sqtructural adhesive in the threaded connection place;
The other end of described air inlet tube 2 and the air inlet person in charge's 1 the other end caliber matches;
The inlet end caliber of described air inlet tube 2 is less than the caliber of air inlet tube 2 the other ends, the air inlet person in charge 1 outlet side pipe path is responsible for the caliber of 1 the other end greater than air inlet, like this in the squeeze casting process, just can not take place because outlet pipe is not small at both ends and big in the middle, cause can not the demoulding situation;
The other end the described air inlet person in charge 1 is established outside thread, establishes internal thread at the other end of air inlet tube 2;
In order to prevent seepage, at the sheathed sealing rubber ring in joint of the air inlet person in charge 1 and air inlet tube 2, do polishing treatment in the joint of the air inlet person in charge 1 and air inlet tube 2.
The sealability of diesel engine air inlet tube described in the utility model is higher, under the hydraulic pressure of 392kPa, lasts 3min and does not have the seepage phenomenon.
