Description

Bent pipe assembly of throttle valve

Technical Field

The utility model belongs to the technical field of auto-parts, especially, relate to a throttle return bend subassembly.

Background

With the rapid development of society, the economic level of people is continuously improved, more and more families buy automobiles, the automobiles are various in variety and greatly different in price, and the purposes of using the automobiles by people are also wide. The valve body is a valve for regulating air intake, and when the engine needs to be regulated from idle speed to high speed, the throttle valve is opened to a large extent. When idling, the air intake is automatically regulated by computer, the air density is changed all the year round, and in order to precisely control the air intake, the air intake is heated and stabilized to a certain temperature. Therefore, the water pipe is blocked, so that the air temperature is lower than the design temperature, and the idle speed is unstable.

The throttle body pipe is usually made of rubber products; however, if the rubber tube is passively influenced by the external force of the metal part for a long time, the metal hardware rubs the rubber tube for a long time, the rubber tube is easily damaged, the medium in the tube body leaks and flows out, and the normal operation of the whole vehicle is influenced after the medium leaks.

Disclosure of Invention

The utility model aims at overcoming the defect that prior art exists, providing a be difficult to the slippage, the body is soft, high quality can satisfy the throttle valve return bend subassembly of the complicated crooked trend in the finite space.

Realize the utility model discloses the technical scheme of purpose is: a throttle elbow assembly comprises a first connecting pipe, an elbow pipe and a second connecting pipe which are sequentially connected; the first connecting pipe is connected with the throttle valve body; the connecting end of the first connecting pipe clamps a water pipe of the throttle valve body through a bulge; the first connecting pipe and the second connecting pipe are respectively composed of an inner rubber pipe, a heat insulation layer and an outer rubber pipe which are sequentially arranged from inside to outside; the bent pipe consists of a corrugated pipe, a fiber reinforced layer and an inner flexible pipe which are sequentially arranged from inside to outside.

According to the technical scheme, the first connecting pipe is connected with the throttle valve body through the rubber sleeve and the clamp; the circumferential surface of the rubber sleeve is provided with a convex block; and the circumferential surface of the clamp is provided with a through hole matched with the convex block.

According to the technical scheme, the connecting end of the first connecting pipe is provided with the pressure release notch which is axially arranged.

According to the technical scheme, the circumferential surface of the first connecting pipe is provided with a step; the protrusions are tightly attached to the steps.

According to the technical scheme, the cross section of the bulge is in a quarter of a circle.

According to the technical scheme, the throttle valve body is provided with the throttle position sensor.

After the technical scheme is adopted, the utility model discloses following positive effect has:

(1) the utility model discloses an inside and outside footpath size is stable in the body, and the uniformity is good, and the cost of manufacture is low, long service life.

(2) The utility model discloses can make first connecting pipe and engine throttle valve body seal effectively and combine, solve the connection problem of first connecting pipe and engine throttle valve body, eliminate potential sealed inefficacy, risk such as drop to the part assembly is easy, can reduce the cost and the weight of spare part.

(3) The utility model discloses a pressure release notch extends to the near-end along the axial of intake pipe from the edge, and the rigidity of tracheal pipe wall when reducing increases the cladding nature of rubber sleeve.

(4) The utility model discloses a step of the protruding setting of adjacent on the first connecting pipe periphery can increase the intensity of bellied department, can effectively prevent the fracture of bellied department in throttle body valve body water pipe course of working.

Detailed Description

(example 1)

Referring to fig. 1 to 4, the present invention includes a first connecting pipe 1, a bent pipe 2 and a second connecting pipe 3 connected in sequence; the first connecting pipe 1 is connected with a throttle valve body 4; the connecting end of the first connecting pipe 1 clamps a water pipe 6 of the throttle valve body 4 through a bulge 5; the first connecting pipe 1 and the second connecting pipe 3 are respectively composed of an inner rubber pipe 7, a heat insulation layer 8 and an outer rubber pipe 9 which are sequentially arranged from inside to outside; the elbow pipe 2 is composed of a corrugated pipe 10, a fiber reinforced layer 11 and an inner flexible pipe 12 which are arranged from inside to outside in sequence.

The first connecting pipe 1 is connected with the throttle valve body 4 through a rubber sleeve 13 and a clamp 14; the circumferential surface of the rubber sleeve 13 is provided with a lug 15; the circumferential surface of the clamp 14 is provided with a through hole 19 matched with the lug 15.

The connection end of the first connection pipe 1 is provided with an axially arranged pressure relief notch 16. The circumferential surface of the first connecting pipe 1 has a step 17; the protrusion 5 is closely attached to the step 17.

The cross-section of the protrusion 5 is a quarter of a circle. A throttle position sensor 18 is mounted on the throttle valve body 4.
