Abstract
The invention discloses a quick choke plug of a pipeline. The quick choke plug comprises a shaft sleeve, wherein a mandrel which can move along the axis direction in the shaft sleeve is arranged in the shaft sleeve; one end of the shaft sleeve is fixedly provided with an elastic plugging part; the mandrel on the other end of the shaft sleeve is connected with a pin, the pin is connected with a handle which can rotate along the axis direction of the pin through a pin hole; the distance from the central point of the pin hole to the side edge of the handle is greater than the distance from the central point of the pin hole to the front top edge of the handle. The distance from the central point of the pin hole of the handle to the side edge of the handle is greater than the distance from the central point of the pin hole to the front top edge of the handle, and the handle rotates along the axis direction of the pin, so that the mandrel 4 can be driven to move along the axis direction in the shaft sleeve 3. Circular rubber is pressed and expanded so as to be tightly fit to the inner wall of the pipeline. The quick choke plug is simple in structure, less in cost investment, reliable in assembling and maintenance and high in practicability.
Description
Technical field
The present invention relates to engine pipelines seal arrangement, be specifically related to a kind of pipeline fast cap.
Background technique
Engine cylinder-body, cylinder cap inside are equipped with circulating cooling water jacket, oil leab and many bolt, screw etc., and by repeatedly investigating and testing discovery, this is also the modal leakage of oil mixing with water.
Produce the reason of this oil mixing with water phenomenon, mainly there is loose, the poor reliability low with leakage check technology level of local organization in gray iron rough-cast qualitatively.Because when hydraulic pressure leak test, can only see and sweat or infiltration phenomenon, and gray iron oilhole peripheral part tissue is if any loose, does not just see at all, can not detect the part of all seepages, likely makes slight or that local organization is loose part installation.Motor operationally, because temperature raises expanded by heating, scurry in the lower water jacket of pressure around loose oil channel hole, is circulated to water tank by the lubricant oil causing pressure higher; Or make cooling water from peripheral part of the water jacket wall of gray iron and cylinder holes, tappet bore, bleed directly or indirectly in the oil sump of motor, also have plenty of because casting or machining error cause various cell walls thin, or water pump packing face is poorly sealed, causes profit to alter logical.
In order to improve the quality of products, in the fabrication process, must thoroughly eliminate all possible factors causing motor oil mixing with water, major measure has following several aspect.
(1) first to improve casting technique level, ensure casting quality, reduce the seepage reject rate of foundry goods.
(2) on foudry line, set up leakage check technology, to understand castability in time, ensure to accomplish not make have the foundry goods of leakage to be sent to machining in a large number, in order to avoid cause human and material resources to waste simultaneously.Especially
It is that the part leaked after machining is too much, easily the part of hidden leak of hiding is let slip installation, causes adverse consequences.
(3) the leakage check technology level after part machining will be improved.Due to the easy climate of casting quality,
Raw material, aluminium coolant-temperature gage and the various factors such as casting technique, operating technology, will eliminate seepage completely real is difficulty.The foundry goods of core skew in some die castingss or mold, also only has and could find after machining to leak.If leak test system sensitivity is not high in manufacture process, the end product quality detected is just unreliable, not easily detects the part with interior leakage or hidden leak of hiding.So, high-caliber leakage check technology must be had after machining, and strict implement process specification, quality of product just can be guaranteed.
(4) infiltration leak-stopping technique to be adopted.In leak test process, to those at insignificant position sheerly local organization loosen and cause the part of leakage or have the suspicious part leaking symbol, adopt infiltration leak stopping process to make up casting defect.Under the condition not loosening leakage check technology requirement, increase infiltration leak-stopping technique, this, to when having a humid climate season or causing the fluctuation of casting quality because of the accident change of a certain casting technological parameter, ensures that the stable of quality of product is effective.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, a kind of pipeline fast cap is provided, by being blocked by engine pipelines fast, carrying out motor leak-testing, thus ensure that engine adds, assembling beat.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
A kind of pipeline fast cap, it comprises axle sleeve, and being provided with in described axle sleeve can along the mandrel that its axial direction moves in described axle sleeve; Described axle sleeve one end is fixed with elasticity closeouts; The mandrel of the described axle sleeve the other end is connected with pin, and described pin is connected with a handle that can rotate along the axial direction of described pin by its pin-and-hole; The distance of top margin before described pin-and-hole central point is greater than described pin-and-hole central point to described handle to the distance of described handle side.
Further technological scheme is elasticity closeouts is round structure.
Further technological scheme is elasticity closeouts is that rubber material is made.
Further technological scheme is that axle sleeve is provided with spacing preiection.
Further technological scheme is that spacing preiection is symmetricly set in the diametric(al) of described axle sleeve.
Further technological scheme is that elasticity closeouts is socketed in described axle sleeve one end.
Further technological scheme is that the axle sleeve the other end is provided with the outer structure extended outward.
Compared with prior art, the invention has the beneficial effects as follows: the distance of top margin before the present invention utilizes the pin-and-hole central point of handle to be greater than described pin-and-hole central point to described handle to the distance of described handle side, and rotate along the axial direction of pin, mandrel 4 just can be driven to move along its axial direction in axle sleeve 3.Thus compression round rubber, make it to expand, be close to inner-walls of duct.Structure of the present invention is simple, and cost drops into less, and assembling, maintenance are reliably, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is status architecture schematic diagram after the use of one embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
As shown in Figure 1 and Figure 2, one embodiment of the invention pipeline fast cap, it comprises axle sleeve 3, and being provided with in axle sleeve 3 can along the mandrel 4 that its axial direction moves in axle sleeve 3; Axle sleeve 3 one end is fixed with elasticity closeouts 2; Specific embodiment is, the present embodiment Elastic closeouts is round rubber material closeouts, and it is socketed in one end of axle sleeve.The axle sleeve one end being socketed with elasticity closeouts can be stretched in the inside of pipeline 1, and preferably, axle sleeve is provided with spacing preiection, spacing preiection is symmetricly set in the diametric(al) of axle sleeve.The mandrel 4 of axle sleeve 3 the other end is connected with pin 5, and axle sleeve 3 the other end is also provided with the outer structure extended outward.Pin 5 is connected with a handle 6 that can rotate along the axial direction of pin 5 by its pin-and-hole; Pin-and-hole central point is greater than the distance A of pin-and-hole central point to handle sinciput limit to the distance B of handle side, and rotates along the axial direction of pin, and mandrel 4 just can be driven to move along its axial direction in axle sleeve 3.Thus compress round rubber closeouts, make it to expand, be close to inner-walls of duct.
