Abstract
This utility model relates to flexible pipe field, especially a kind of Pcv valve flexible pipe, solve current flexible pipe and be connected with Pcv valve door that to there is ruggedness the highest, the technical problem that gas leak phenomenon is more, it includes the body of both ends open, it is characterized in that: described body is provided with stiffening ring for the mouth of pipe end outer wall connecting Pcv valve connector, be in the inboard wall of tube body inside described stiffening ring and be provided with the sealing ring of projection.This utility model is by increasing stiffening ring and sealing ring, it is achieved preferably with the connection sealing of Pcv valve, the ruggedness of improving product and strong degree, meets people to the highest prescription of automobile product and expectation.
Description
Technical field
This utility model relates to flexible pipe field, especially one and is used for connecting Pcv valve flexible pipe.
Background technology
Pcv valve is made up of valve body, valve, valve gap, spring, undecomposable.Its Main Function is: by Pcv valve, the gas in crankcase is imported inlet manifold, and has a small amount of air to be directly entered inlet manifold by air filter through Pcv valve, avoiding problems icing, the phenomenons such as insufficient, deterioration of emission of burning at air throttle.
Need hose connection between Pcv valve and air filter, the connector of Pcv valve is mostly structure as shown in Figure 2 at present, and existing flexible pipe and Pcv valve connector realize sealing effectiveness mainly by interference fit, and strong degree is the highest, As time goes on, the phenomenon often leaked air.Along with people are more and more higher to the requirement of automobile product, develop more robust and firm Pcv valve connection flexible pipe and increasingly paid attention to by automobile vendor.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, the Pcv valve flexible pipe that connection sealing is good to solve the deficiency of above-mentioned technology.
In order to achieve the above object, Pcv valve flexible pipe designed by this utility model, including the body of both ends open, it is characterized in that: described body is provided with stiffening ring for the mouth of pipe end outer wall connecting Pcv valve connector, be in the inboard wall of tube body inside described stiffening ring and be provided with the sealing ring of projection.
As optimization, described stiffening ring is set in outside described body, the thickness of described stiffening ring and body consistency of thickness.
As optimization, described sealing ring cross section is right angled triangle, and longer right-angle side is close to inboard wall of tube body, and another right-angle side is in inside body.
As optimization, described sealing ring is bonding with inboard wall of tube body.
Pcv valve flexible pipe obtained by this utility model, by increasing stiffening ring and sealing ring, it is achieved preferably with the connection sealing of Pcv valve, the ruggedness of improving product and strong degree, meets people to the highest prescription of automobile product and expectation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of current Pcv valve connector.
Detailed description of the invention
The utility model will be further described to combine accompanying drawing below by embodiment.
Embodiment 1:
As it is shown in figure 1, the Pcv valve flexible pipe that the present embodiment describes, including the body 1 of both ends open, described body 1 is provided with stiffening ring 2 for the mouth of pipe end outer wall connecting Pcv valve connector, is in body 1 inwall inside described stiffening ring and is provided with the sealing ring 3 of projection.The setting of stiffening ring 2 makes restoring force at the mouth of pipe increase, and after being connected such as the Pcv valve connector 4 of Fig. 2, draws power in bigger, it is ensured that inboard wall of tube body and Pcv valve connector 4 compact siro spinning technology.Described stiffening ring 2 is set in outside described body 1, and the thickness of described stiffening ring 2 and body consistency of thickness, while facilitating flexible pipe to be inserted in Pcv valve connector 4, the inboard wall of tube body at stiffening ring is completely embedded with connector 4.
Described sealing ring 3 cross section is right angled triangle, and longer right-angle side is close to inboard wall of tube body, and another right-angle side is in inside body, match with the structure of Pcv valve connector 4, inboard wall of tube body is low with the voidage of connector, increases the service life, it is to avoid the generation of gas leak phenomenon.Described sealing ring 3 is bonding with body 1 inwall, easy to process.
Claims (4)
1. a Pcv valve flexible pipe, body (1) including both ends open, it is characterized in that: described body (1) is provided with stiffening ring (2) for the mouth of pipe end outer wall connecting Pcv valve connector, be in the body inside described stiffening ring (1) inwall and be provided with the sealing ring (3) of projection.
A kind of Pcv valve flexible pipe the most according to claim 1, is characterized in that: described stiffening ring (2) is set in described body (1) outward, the thickness of described stiffening ring (2) and body consistency of thickness.
A kind of Pcv valve flexible pipe the most according to claim 1, is characterized in that: described sealing ring (3) cross section is right angled triangle, and longer right-angle side is close to inboard wall of tube body, and another right-angle side is in inside body.
A kind of Pcv valve flexible pipe the most according to claim 3, is characterized in that: described sealing ring (3) is bonding with body (1) inwall.
