Abstract
The invention relates to the technical field of sealing property tests, and discloses a method for detecting sealing property of plate parts. The method comprises the following steps: step S1, coating liquid soap on a to-be-detected plate part; S2, preparing a cylinder which is smooth on the bottom, placing the cylinder on the to-be-detected plate part, so as to form a sealing cavity between the cylinder and the to-be-detected plate part; S3, using a vacuum pump to vacuate the sealing cavity; S4, and observing whether the to-be-detected plate part has bubbles in real time, if bubbles occur, the sealing property of the part being poor, and if no bubbles occur, the sealing property of the part being good. The method uses the vacuum-pumping method to detect. In detection, the part is coated with the liquid soap, and the cylinder is placed on the to-be-detected plate part, and the vacuum pump is started, and then the sealing property of the part can be determined through observing whether bubbles occur on the to-be-detected plate part.
Description
Technical field
The present invention relates to sealing property method of testing, more particularly, a kind of particularly method detecting plate parts sealing property.
Background technology
Higher equipment is required for sealing property, especially the main equipment such as boats and ships, because this kind equipment is use plate part welding to be bolted together mostly.When the sealing difference of plate parts, be easy to lead to great security incident.Therefore, how designing one can carry out sealing property detection to plate parts fast, is one of direction of studying of those skilled in the art to get rid of the method for potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of method that can realize the detection plate parts sealing property detected fast.
In order to achieve the above object, the technical solution used in the present invention is as follows:
Detect a method for plate parts sealing property, comprise the following steps:
Step S1, on plate parts to be detected, be coated with liquid soap;
Cylinder body smooth bottom step S2, preparation one, and this cylinder body is placed on described plate parts to be detected, to make to form a seal chamber between cylinder body and plate parts to be detected;
Step S3, adopt a vacuum pump by seal chamber vacuum state;
Whether the plate parts that step S4, real-time observation are to be detected occurs bubble, if there is bubble, this plate member seals poor performance, if bubble-free, this plate member seals performance is good.
Preferably, the bottom being also included in cylinder body before being placed in by cylinder body on described plate parts to be detected is in step s 2 provided with flexible annular parts.
Preferably, whether the plate parts that observation real-time is in step s 4 which to be detected occurs the concrete grammar of bubble is in cylinder body, be provided with at least one groove, and be provided with transparency cover in cylinder body upper end; Namely can be observed whether plate parts to be detected occurs bubble through transparency cover and groove.
Preferably, described flexible annular parts adopt sponge material to make.
Preferably, described transparency cover adopts transparent plastic to make.
Compared with prior art, the invention has the advantages that: the present invention adopts the method vacuumized to detect, during detection, liquid soap coated by plate, again cylinder body is placed on plate to be detected, and start vacuum pump, by observing on plate to be detected whether occur bubble, and then judge the sealing property of plate to be detected.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the process flow diagram of the method for detection plate parts sealing property of the present invention.
Fig. 2 is the front view for realizing the vacuum extractor that method of the present invention designs.
Fig. 3 is the vertical view of vacuum extractor in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Consult shown in Fig. 1, the invention provides a kind of method detecting plate parts sealing property, comprise the following steps:
The first step, on plate parts to be detected, be coated with liquid soap;
Cylinder body 2 smooth bottom second step, preparation one, and this cylinder body 2 is placed on described plate parts to be detected, to make to form a seal chamber between cylinder body 2 and plate parts to be detected.In order to improve precision and the efficiency of detection, need to be provided with flexible annular parts 3 in the bottom of cylinder body 2 in advance.These flexible annular parts 3 preferably adopt sponge material to make.
3rd step, adopt a vacuum pump 8 by seal chamber vacuum state;
Whether the plate parts that the 4th step, real-time observation are to be detected occurs bubble, if there is bubble, this plate member seals poor performance, if bubble-free, this plate member seals performance is good.Specifically need in cylinder body 2, be provided with at least one groove 10, and be provided with transparency cover 1 in cylinder body 2 upper end; Namely can be observed whether plate parts to be detected occurs bubble through transparency cover 1 and groove 10.This transparency cover 1 preferably adopts transparent plastic to make.
The method that vacuumizes of employing of the present invention's innovation carries out sealing property to plate, due to when detecting, liquid soap is coated in advance on plate, again cylinder body is placed on plate to be detected, and start vacuum pump, by observing on plate to be detected whether occur bubble, and then judge the sealing property of plate to be detected.Generally, the method has simple, practical advantage.
Consult shown in Fig. 2 to Fig. 3, in order to realize the vacuum extractor that method of the present invention designs, this vacuum extractor mainly comprises transparency cover 1, cylinder body 2, flexible annular parts 3 and vacuum pump 8, wherein, cylinder body 2 is provided with at least one groove 10, and transparency cover 1 is installed on the upper end of cylinder body 2, and flexible annular parts 3 are installed on the lower end of cylinder body 2, the opening in communication of cylinder body 2 and flexible annular parts 3, vacuum pump 8 is communicated with cylinder body 2.
Although describe embodiments of the present invention by reference to the accompanying drawings; but patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection domain described by claim of the present invention, all should within protection scope of the present invention.
