Description
Technical field
The invention belongs to the technical fields of car engine structure design and manufacture, are related to the Pcv valve of positive crankcase ventilation (PCV)
Structure.More particularly it relates to a kind of automobile Pcv valve sebific duct adapter.
Background technique
The Pcv valve of positive crankcase ventilation (PCV) is that essential part, main function are in automobile engine: unburned mixed
It closes gas and leaks into crankcase (being commonly called as gas blowby) from piston ring at elevated pressures, gas blowby is inhaled into air inlet by Pcv valve and Pcv valve sebific duct
Enter combustion chambers burn in system.
In the prior art, Pcv valve sebific duct is thicker, and material is softer, and the Pcv valve sebific duct of some engines is true greatly in inlet manifold
It is flat by suction when reciprocal of duty cycle, it causes the inspiratory capacity of gas blowby to reduce, or even burning can not be inhaled into, thus can dilute the machine in crankcase
Oil keeps machine oil rotten, causes engine parts premature abrasion；Moreover, sebific duct it is prolonged and repeated suction it is flat will also result in sebific duct rupture,
It falls off and gas leakage, causes atmosphere pollution.
Summary of the invention
The present invention provides a kind of automobile Pcv valve sebific duct adapter, deformed in air-breathing the purpose is to solving Pcv valve sebific duct and
The problem of influencing engine work.
To achieve the goals above, the technical scheme adopted by the invention is as follows:
Automobile Pcv valve sebific duct adapter of the invention, the Pcv valve sebific duct include Pcv valve sebific duct one, Pcv valve sebific duct
Two, the Pcv valve sebific duct adapter adds glass fiber material to be made by nylon, and both ends are respectively by Pcv valve sebific duct one, Pcv valve glue
Pipe two connects.
The Pcv valve sebific duct adapter includes hard tube and the ring head at both ends, the Pcv valve glue among adapter
Guan Yi, Pcv valve sebific duct two are set with and are clamped on the ring head.
The ring head is the protrusion of more piece annular, described on the vertical section of the Pcv valve sebific duct adapter
Protrusion is zigzag, and the inclined-plane of sawtooth is towards the outer end of ring head.
The quantity of the protrusion of the annular is three or more than three.
The ring head and Pcv valve sebific duct is using interference fit.
The Pcv valve sebific duct one and Pcv valve sebific duct two is all made of rubber hose.
The length of the Pcv valve sebific duct one and Pcv valve sebific duct two is respectively less than the length of Pcv valve sebific duct adapter.
By adopting the above technical scheme, Pcv valve sebific duct adapter uses the higher nylon of hardness and strength and glass to the present invention
The composite material of fiber, low cost and efficiently solves Pcv valve sebific duct and is inhaled flat problem；The both ends of Pcv valve sebific duct adapter
Using with anticreep, sealing function ring head design and ring head and sebific duct be interference fit, the concaveconvex structure of ring head and
Deformed sebific duct fits closely, to be interlocked, it is difficult to fall off；Bulge-structures more than three sections can play multi-sealed
Effect；The length of Pcv valve sebific duct designs shorter as far as possible, allows what it mainly rose to be connection function rather than ventilate, shortens
The rigidity of sebific duct can be improved in its length, prevents from inhaling when negative pressure is big flat；Length can be increased and decreased according to the actual situation and change is tubular,
To be suitable for various types of engines.

Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
Expressed structure of the invention as shown in Figure 1, Figure 2 is a kind of automobile Pcv valve sebific duct adapter.It is existing in order to overcome
Technology there are the problem of and defect, realization solve the problems, such as that Pcv valve sebific duct deforms in air-breathing and influences engine work
Goal of the invention, the technical scheme adopted by the invention is as follows:
As shown in Figure 1 to Figure 2, automobile Pcv valve sebific duct adapter of the invention, the Pcv valve sebific duct includes Pcv valve glue
Pipe 1, Pcv valve sebific duct 23, the Pcv valve sebific duct adapter 2 add glass fiber material to be made by nylon, and both ends are respectively by PCV
Valve sebific duct 1, Pcv valve sebific duct 23 connect.
By installing a dedicated adapter additional among Pcv valve sebific duct, it is flat by suction that Pcv valve sebific duct can be effectively prevented.
Glass fiber material is added using the higher nylon of hardness and strength, hard tube part replaces rubber hose among adapter, has
Effect ground solves the problems, such as that Pcv valve sebific duct is flat by suction, and cost is very low.The present invention can increase and decrease length and change pipe according to the actual situation
Shape, to be suitable for various engines.
As shown in figure 3, first Pcv valve sebific duct 1 and Pcv valve sebific duct 23 are connected and fixed with Pcv valve sebific duct adapter 2, so
The connector of Pcv valve sebific duct 1 and 2 both ends of Pcv valve sebific duct respectively with Pcv valve and inlet manifold is connected and fixed afterwards.
The Pcv valve sebific duct adapter 2 includes hard tube 4 and the ring head 5 at both ends, the PCV among adapter
Valve sebific duct 1, Pcv valve sebific duct 23 are set with and are clamped on the ring head 5.
The design of double ring heads of Pcv valve sebific duct adapter 2 guarantees that PCV sebific duct is not inhaled flat and prevents from revealing.
The ring head 5 is the protrusion of more piece annular, described on the vertical section of the Pcv valve sebific duct adapter 2
Protrusion be zigzag, the inclined-plane of sawtooth is towards the outer end of ring head 5.
The quantity of the protrusion of the annular is three or more than three.
The ring head 5 and Pcv valve sebific duct is using interference fit.
The both ends of Pcv valve sebific duct adapter 2 use the ring head design with anticreep, sealing function, ring head and sebific duct
It is interference fit, the concaveconvex structure of ring head is fitted closely with deformed sebific duct, to be interlocked, it is difficult to fall off；Three
Bulge-structure more than section can play multi-sealed effect.
The Pcv valve sebific duct 1 and Pcv valve sebific duct 23 is all made of rubber hose.
Preferably, role is easy for installing and is suitable for installing the variation of link position, adjustment the flexibility of rubber hose.
The length of the Pcv valve sebific duct 1 and Pcv valve sebific duct 23 is respectively less than the length of Pcv valve sebific duct adapter 2.
The length of Pcv valve sebific duct 1 and Pcv valve sebific duct 23 designs shorter as far as possible, and allow it mainly rises is that connection is made
With rather than ventilate, shortening its length can be improved the rigidity of sebific duct, prevent from inhaling when negative pressure is big flat.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
