Abstract
The invention provides a sealing device with stepless adjustment type outside diameter. The sealing device with the stepless adjustment type outside diameter comprises an adjustable sealing rod, a sealing rubber part, a guide sleeve, a sealing rod fixing device, a sealing rod fixing device body and a hinge pin, wherein a thread structure is arranged on the adjustable sealing rod; the adjustable sealing rod is connected with the sealing rod fixing device through the thread structure; the sealing rod fixing device is connected with the sealing rod fixing device body through the hinge. With the adoption of the sealing device, the sealing problem of a water pipe sealing part can be solved, and the bearing capacity of the water pipe sealing part is greatly improved; the problems such as poor sealing and easy spring out of the sealing part in the prior art can be solved; meanwhile, compared with a traditional structure, the above structure has the advantages that a quick-wear part can be easily replaced, and the service life of the quick-wear part is long, so that the cost can be saved.
Description
Technical field
The present invention relates to a kind of external diameter infinitely variable sealing device, particularly relate to the cooling in a kind of egr system
Device external diameter infinitely variable sealing device.
Background technology
The EGR valve of domestic production at present uses such a structure mostly: as it is shown in figure 1, the opening and closing of EGR valve are adopted
With hoisting type, the most on the same line, there is gas circulating resistance big in EGR valve air inlet and gas outlet, incipient opening force is big,
The problem being difficult to mounting arrangements on electromotor.
Cooler is to cool down the engine air in supercharging, the most clean-burning device.Cooler at present
Industry major product is to be cooled to master by water, reaches to cool down the purpose of gas circuit.In egr system can steam in combustion tail gas again
Content can not transfinite, therefore needs to keep good air-tightness between cooler gas circuit and water route.
If Fig. 1 is the sealing device of currently available technology: when trip gear body 5, adjustable sealing bar 1 moves to right compression
Caulking gum part 2, the thickness of caulking gum part 2 is 5mm, swell increment is less, and sealing is poor, and easy to wear, simultaneously apparatus body 5
The mode of pulling is centrage and locking during guide pin bushing 3 central axis, is unfavorable for that operator operate.Caulking gum part 2 swell increment
Little to directly result in sealability poor, even sealing member abjection, accidents caused.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of adjustable during cooler gas is examined
The infinitely variable sealing device of energy excellent sealing water route water pipe port.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows:
A kind of external diameter infinitely variable sealing device, fixes including adjustable sealing bar, caulking gum part, guide pin bushing, seal bar
Device and apparatus body, bearing pin, described adjustable sealing bar is provided with the fixing dress of helicitic texture, adjustable sealing bar and seal bar
Putting and connected by helicitic texture, seal bar fixing device and apparatus body are connected by bearing pin.
Owing to have employed above technical scheme, the invention technological progress is as follows:
The sealing device of the present invention can improve the sealing problem of water pipe sealing member very well, and bearing capacity is greatly reinforced, and solves existing
Sealing member is had in technology to seal loosely, the problem such as easy ejection.Meanwhile, the more conventional structure of this structure is more easy to change consumable accessory, rapid wear
Part is the most relatively long for service life, cost-saved.
Additionally this sealing device is more suitable for operator's operation than the structure of currently available technology, is not likely to produce fatigue.
Accompanying drawing explanation
Fig. 1 is prior art water pipe sealing device figure；
Fig. 2 is present configuration water pipe sealing device figure；
Fig. 3 is the sectional view of present configuration water pipe sealing device.
Wherein: 1-adjustable sealing bar, 2-caulking gum part, 3-guide pin bushing, 4-seal bar fixing device, 5-device
Body,
6-bearing pin, 7-helicitic texture.
Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 2 and Figure 3: a kind of external diameter infinitely variable sealing device, including adjustable sealing bar 1, caulking gum
Part 2, guide pin bushing 3, seal bar fixing device 4 and apparatus body 5, bearing pin 6, adjustable sealing bar 1 is provided with helicitic texture 7, scalable
Seal bar 1 and seal bar fixing device 4 are connected by helicitic texture 7.Thus realize the step-less adjustment of water pipe sealing member.This structure
Active force produced by 0.6Mpa air pressure, external diameter range of accommodation 1-3mm can be overcome.
Adjustable sealing bar 1 and caulking gum part 2 are filled in water pipe to be sealed, trip gear body 5 to centrage with lead
Overlapping 3 centrages to overlap, owing to eccentric throw becomes big, make 1 to move right, so that caulking gum part 2 tightens up expansion, external diameter becomes big,
Realize the purpose sealed.When water pipe internal diameter size becomes big, rotate adjustable sealing bar 1.Due to adjustable sealing bar 1 and sealing
Being threaded between lever fixing apparatus 4, therefore adjustable sealing bar 1 is to the right, caulking gum part 2 external diameter in a free state becomes
Greatly, work external diameter also increases, therefore is suitable for the state that water pipe becomes large-sized.When changing caulking gum part 2, derotation adjustable sealing
Bar 1 is until adjustable sealing bar 1 disengages with seal bar fixing device 4, and the most desirable lower seal rubber parts 2 is replaced.
