Description
Technical field
The utility model is related to technical field of fastening, and in particular to a kind of booster water pipe bolt.
Background technology
In current engine Engineering Design, for booster using more and more common, so-called supercharging is exactly that air is advance
Then compression feeds cylinder again, increase a technology of air inflow to improve atmospheric density.Engine with supercharger is to utilize engine
The energy of portion drives turbocharger, and then improve admission pressure in exhaust manifold, increases air inflow, to improve hair
The dynamic property of motivation.Turbocharged engine delivery temperature is higher, and turbocharger temperature is caused to increase, and excessively high temperature is right
It booster reliability and durable has an impact, it is therefore desirable to which turbocharger is cooled down.
Under normal circumstances, since booster surface temperature is higher, water inlet pipe cannot be carried out close by common sealing ring
How envelope connects booster and water inlet pipe, ensures that water flow appropriate enough enters booster, and ensure that water pipe is close with booster
Envelope has no a kind of low cost, easy mode before.
Utility model content
(1) the technical issues of solving
The purpose of this utility model be find a kind of low cost, convenient mode solves that water inlet pipe connect with booster asks
Topic.
(2) technical solution
In order to achieve the above object, the utility model is achieved by the following technical programs：A kind of booster water pipe bolt,
It is characterised in that it includes being provided with externally threaded nut body, transition part is equipped on the right side of the nut body, in the mistake
Portion is crossed equipped with through-hole, the nut body and the transition part are interior equipped with cylinder groove, are set on the right side of the transition part
There is head, the head is cylinder design, is equipped with interior hexagonal groove in the head, the depth of the interior hexagonal groove is little
In the 1/2 of the head length, the interior hexagonal groove is concentric design with the cylinder groove, the cylinder groove
The area of cross section is less than the area of the cross section of the interior hexagonal groove.
Preferably, the diameter of the nut body is equal to the diameter of the transition part.
Preferably, the head and the junction of the transition part are equipped with fillet, and the radius of the fillet is not more than
0.6cm。
(3) advantageous effect
The utility model provides a kind of booster water pipe bolt, has the following advantages：First by the ball stud of water pipe
It is sleeved on the transition part of mutual cooperation, and diaphragm seal is set on the both sides of ball stud, then and nut body is screwed into increasing
On depressor, the diaphragm seal between ball stud and head and the diaphragm seal completion pair between booster and ball stud are thus relied on
The seal operation of ball stud, then water pipe is defeated by water by the fluid hole to cooperate with through-hole being preset on ball stud
Send to cylinder groove, then and flow enters along cylinder groove in booster, in this way, avoid by oil or water pipe directly with
High temperature caused by booster connection influences and sealing problem.
By inventor's numerous experiments, it is found that the junction of head and transition part must be provided with fillet, and radius of corner
0.6cm is must not exceed, after placing copper diaphragm seal, sealing effect is more preferable herein, is less susceptible to leakage problem occur, falls 45% on a year-on-year basis
Leakage possibility.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is another structure diagram of the utility model.
Fig. 3 is the utility model side view.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of booster water pipe bolt, which is characterized in that
Nut body 2 including being provided with external screw thread 1 is equipped with transition part 3 on the right side of the nut body, is set on the transition part
There is through-hole 4, be equipped with cylinder groove 5 in the nut body and the transition part, head is equipped on the right side of the transition part
6, the head is cylinder design, and interior hexagonal groove 7 is equipped in the head, and the depth of the interior hexagonal groove is not more than institute
State the 1/2 of head length, the interior hexagonal groove and the cylinder groove are concentric design, the cylinder groove it is transversal
The area in face is less than the area of the cross section of the interior hexagonal groove.
Preferably, the diameter of the nut body is equal to the diameter of the transition part.
Preferably, the head and the junction of the transition part are equipped with fillet 8, and the radius of the fillet is not more than
0.6cm。
Working method and principle：In use, being equipped with fluid hole in the ball stud of water pipe, then and ball stud is sleeved on
On the transition part of mutual cooperation, fluid hole is made to be corresponded with the through-hole on transition part, prevent two side leakages of ball stud at this time
Liquid can respectively place a bronze medal diaphragm seal in the both sides of ball stud, i.e. copper diaphragm seal is also sleeved on transition part, then and in dependence
The utility model is quickly screwed in booster designated position by hexagonal groove, and is tightened, by between ball stud and head
Copper diaphragm seal between copper diaphragm seal and booster and ball stud completes the seal operation to ball stud, and then water pipe passes through
Be preset in water is delivered in cylinder groove with the fluid hole that through-hole cooperates on ball stud, then and flow along circle
Column recesses enter in booster, in this way, avoid by oil or water pipe directly connect with booster caused by high temperature influence and it is close
Envelope problem.
It should be noted that herein, relational terms such as first and second and the like are used merely to a reality
