As an embodiment of the present invention, it should be noted that, the present embodiment is described by taking a ball valve as an example, but the practical application is not limited to a ball valve, and any valve body having the same principle as the ball valve may be applied, and the same principle specifically refers to that a valve core can be driven to move by rotating a handle, so as to achieve the purpose of controlling the flow rate and the flow direction of the flowing medium to a certain extent.
The ball valve is a common valve body, is a starting and closing element, and a handle drives a valve rod to make the valve rotate around the axis of the ball valve, or can be used for regulating and controlling fluid. The ball valve is mainly used for cutting off, distributing and changing the flow direction of a medium in a pipeline, and can be closed tightly only by rotating 90 degrees and a small rotating moment. The ball valve is most suitable for being used as a switch and a stop valve.
In practical application, the connecting plate 6 is detachably fixed on the mounting plate 1 by using a fastener, such as a snap connection or a bolt connection, when the mounting plate 1 is actually used, the mounting plate can be placed on the ground of a workshop where the mounting plate 1 is located through a supporting component, the height of the mounting plate 1 can be set according to a batch or multiple batches of valve body bodies 3 with similar specifications to be detected, the specifications indicated in the embodiment are similar, and specifically means that the diameter of the pipe joints on two sides of the valve body 3 used for being connected is the same as the height of the proportional position of the pipe joints relative to the whole valve body 3. After the position of the mounting plate 1 is determined, the position of the hot melt adhesive extrusion mechanism 2 can also be determined, before the containing shell 201 is installed, pressure oil is filled into the containing shell 201, at this time, a pressurizing element in the containing shell 201 is opened, the most common pressurizing element on the market is a pneumatic pressurizing element, also called a pneumatic booster pump, which is an element that applies work by the pressure intensity or the force generated by expansion of gas, i.e., a machine member that converts the elastic energy of compressed air into kinetic energy, such as a cylinder, a pneumatic motor, a steam engine, etc., the pneumatic element is in a power transmission form, also is an energy conversion device, and utilizes the gas pressure to transmit energy. The pneumatic pressurizing element is simple and portable in structure and simple to install and maintain, the medium is air and is not easy to burn compared with a hydraulic medium, and the pneumatic pressurizing element is not easy to mix with pressure oil in the containing shell 201, so that the pneumatic pressurizing element is safe to use. The working medium of the pneumatic pressurizing element is inexhaustible air which is not expensive. The exhaust gas treatment is simple, the environment is not polluted, the cost is low, the output force and the working speed are very easy to adjust, the action speed of the cylinder is generally less than 1M/S, the action speed is higher than that of a hydraulic mode and an electric mode, the reliability is high, the service life is long, the energy can be stored, the centralized gas supply is realized, the energy can be released in a short time, the high-speed response in intermittent motion is obtained, the buffering can be realized, and the impact load and the overload have stronger adaptability. In the present design, the piston plate in the pressurizing element is in the containing shell 201, the containing shell 201 is regarded as a piston cylinder, and the piston motion is performed in the containing shell 201, so that the pressure oil is squeezed into the valve body 3 and the pressurizing of the pressure oil is performed in the valve body 3 under one pushing. Under certain conditions, the pneumatic device can be made to have self-holding capacity. From the above, it can be known that the pressure oil in the container casing 201 can be pushed out under the action of the pressurizing element also in the container casing 201, so that the pressure oil is filled into the valve body 3, and the common operation mode for detecting the tightness of the valve body 3 is as follows: firstly, the valve body 3 is in a half-open state, and the two ends of the valve core are sealed by flange covers with pipe joints. Then introducing pressure oil into the pipe joint at one end, and simultaneously plugging the pipe joint at the other end; after the pressure is gradually increased to 5.6bar, the air inlet valve is closed to stop air inlet. Then the handle is rotated, the ball valve is closed after the handle is rotated for a plurality of times, and the other end, namely the pipe joint of the non-pressure oil introduction end is opened, so that the pressure in the cavity is reduced to the atmospheric pressure. And finally, under the test pressure of 5.6bar, within the time of more than 5min, the pressure of the air inlet cavity can not be reduced, and the air tightness of the valve body 3 at the moment can be judged to be reliable. It is known that the pressure gauge used should be of the order of 0.4 and the range 10 bar. When needed, oil absorption paper can be pasted at the pipe joint at the other end where pressure oil is introduced, when an oil stain seepage position exists on the oil absorption paper, whether the ball valve leaks oil can be judged, and if no oil seeps out, the sealing performance of the valve body 3 is proved to be reliable. The test was then repeated by introducing pressurized oil from the other end. After the hot melt adhesive extrusion mechanism 2 is removed, pressure oil in the valve body 3 is cleaned, the flange covers at the two ends are removed, sealing residues on sealing surfaces at the two end parts of the ball valve are removed, and if residues enter the valve hole, the sealing residues are removed and cleaned.
Further, in order to improve the tightness of the connection between the containing housing 201 and one of the pipe joints of the valve body 3, when the containing housing 201 is inserted into the valve body 3, the hot melt adhesive output ring 204 is moved to the position located at the edge of the pipe joint, at this time, the external controller is turned on, the hot melt adhesive filled in the hot melt adhesive output ring 204 is controlled to be melted by the temperature of the heating plate and to move continuously toward the inside of the valve body 3 and to move by the extruded hot melt adhesive output ring 204, so that the hot melt adhesive output ring 204 made of rubber deforms, and the heated hot melt adhesive located in the cavity is extruded, at this time, the external controller is turned off, so that the heating plate stops heating and gradually condenses the hot melt adhesive, and because the condensation speed of the hot melt adhesive is higher under an atmospheric pressure, after the condensed adhesive is condensed, can pack hot melt adhesive output ring cover 204 with set up the gap between the screw thread on the coupling of valve body 3 automatically to compare prior art and directly pour into pressure oil into, the negative effects when this embodiment can be brought to valve body 3 detection time through having the gap that automatic filling ability eliminated between hot melt adhesive extrusion mechanism 2 and the valve body 3, thereby make this design have higher detection credibility, avoided because the action of the interior case leakproofness of valve body 3 of repeated check valve body that the reason of gap oil leak leads to. The material of heating plate is the metal, and specific heating methods can be the heat that the electric current directly produced when heating to the metal that possess the big resistance or also can be the induction heating of electric current, and when selected heating methods was induction heating, the heating plate did not design into and is formed by a plurality of metal heating pipe combinations, metal heating pipe's theory of operation be adorned on same iron core a more primary coil of the number of turns and a less secondary coil of the number of turns. The ratio of input to output voltage is equal to the ratio of the number of turns of the coil while the energy remains constant. Therefore, the secondary coil generates a large current under a low voltage condition. For induction heaters, the bearing is a short-circuited single-turn secondary coil that passes large currents at low ac voltages, thereby generating significant heat. The heater itself and the yoke are kept at normal temperature. It is noted that since this heating method induces a current, the bearing is magnetized. It is important to ensure that the bearing is subsequently demagnetized so that it does not pick up metallic swarf during operation. The FAG induction heater has an automatic degaussing function.
In one aspect of this embodiment, in order to further improve the tightness of the connection between the hot melt adhesive output collar 204 and the pipe joint of the valve body 3, the shape of the hot melt adhesive output collar 204 may be designed to be a truncated cone, and the small end of the round table shape is arranged towards the valve core in the valve body 3, so that when the hot melt adhesive output ring sleeve 204 is pushed inwards, so that the hot melt adhesive in the hot melt adhesive output ring sleeve 204 is extruded while being pushed, and when the hot melt adhesive output ring sleeve 204 and the pipe joint of the valve body 3 relatively move to a certain degree, the effect of the free deformation of the hot melt adhesive output ring sleeve 204 can also enable the hot melt adhesive output ring sleeve 204 and the pipe joint of the valve body 3 to carry out certain expansion sealing, so that the reliability of the design in the process of detecting the air tightness of the valve body 3 is further improved.
In another case of this embodiment, the shape of the hot melt adhesive output ring sleeve 204 may be designed to be a drum shape with two inclined sides and a bulging middle, so as to improve that when the accommodating housing 201 is pushed by the push rod to drive the hot melt adhesive output ring sleeve 204 to move, the hot melt adhesive output ring sleeve 204 can easily enter the pipe joint of the valve body 3, and the inclined surface on one side of the hot melt adhesive output ring sleeve 204 and the inner wall of the pipe joint of the valve body 3 slide relatively, so that even if the axes of the hot melt adhesive output ring sleeve 204 slightly deviated in position and the pipe joint of the valve body 3 are not overlapped, the hot melt adhesive output ring sleeve 204 can smoothly enter the pipe joint of the valve body 3 under the self-positioning effect of the inclined surface, and a certain extrusion force is generated on the hot melt adhesive output ring sleeve 204 at the bulging outer edge of the second half pipe joint of the pipe joint, so that the hot melt adhesive output ring sleeve 204 can be connected with the inner wall of the valve body 3 in a relatively fitting manner. In this embodiment, a truncated-cone shaped hot melt adhesive output collar 204 is preferred.
In another case of this embodiment, the hot melt adhesive output ring sleeve 204 is fixedly connected to the outside of the accommodating housing 201, and at this time, the accommodating housing 201 needs to be driven by the push rod through pushing the mounting plate 1 and the hot melt adhesive output ring sleeve 204 is further driven to be continuously inserted into the valve body 3.
In another situation of this embodiment, hot melt adhesive output ring cover 204 rotates to be connected on splendid attire casing 201, works as when the edge extrusion hot melt adhesive output ring cover 204 of the coupling of valve body 3, can be through rotating hot melt adhesive output ring cover 204, make the inside hot melt adhesive of hot melt adhesive output ring cover 204 cavity is extruded to under the drive of pivoted hot melt adhesive output ring cover 204, further wipe the hot melt adhesive that is located gap between hot melt adhesive output ring cover 204 and the valve body 3 evenly, the inseparability when further improving the hot melt adhesive and sealing has improved the reliability of this design when detecting the gas tightness greatly. It can be known that the hot melt adhesive melts when being heated, and the distance between the hot melt adhesive molecules is increased, so that the volume of the hot melt adhesive output ring sleeve 204 is increased to a certain extent, and the deformation degree of the hot melt adhesive output ring sleeve 204 when being extruded by the pipe joint of the valve body 3 is further increased; the present embodiment preferably has a rotatable connection between the hot melt adhesive output ring 204 and the valve body 3.
Further, when the hot melt adhesive output ring sleeve 204 extends into the valve body 3 and is extruded with the edge of the valve body 3 to a certain extent, in order to maintain the stability of the valve body 3 when the pressure oil is filled subsequently, a clamp 203 is further provided according to the detected shape of the valve body 3, a part of the extension housing often extends from the outer edge of the pipe joint of most existing valve bodies 3, when the hot melt adhesive output ring sleeve 204 and the valve body 3 are extruded, the clamp 203 contacts with the part of the extension housing, specifically, when the part of the extension housing extrudes one side of the clamp 203, the clamp 203 rotates, so that the other side of the clamp 203 continuously clamps the part of the extension housing from the outer side, as required, a plurality of clamps 203 may be provided, in this embodiment, the preferred number of the clamp 203 is three, and the three chucking clamps 203 are uniformly arranged on the supporting plate 202, because the three chucking clamps 203 which are uniformly arranged can apply a resultant force which is directed to the center of the circle of the supporting plate 202 in one direction to the valve body 3 while clamping the valve body 3, the stability between the valve body 3 and the hot melt adhesive extruding mechanism 2 can be improved when pressure oil is infused.
In a condition of this embodiment, the inboard of chucking clamp 203, promptly on the position of the extension casing contact of chucking clamp 203 and the coupling department of valve body 3's the fixedly connected with slipmat still, the kind of slipmat can be rubber slipmat, PVC slipmat, PU slipmat, AB glue slipmat, silica gel slipmat etc. and these slipmats low price and acquisition mode are simple, so can be used for improving chucking clamp 203 grasps the fastening degree to valve body 3, improves the reliability of this design when using.
Further, a notch for accommodating the clamping clip 203 is formed on the supporting plate 202. In order to prevent the valve body 3 from interfering during rotation, the notch is formed, and meanwhile, the notch can also shorten the distance between a part of the extension shell outside the valve body 3 and the support plate 202, so that the distance between the part of the extension shell and the clamping clamp 203 when the extension shell is extruded can be shortened, the ease of extruding the extension shell to the clamping clamp 203 is improved, and it can be known that the notch can be reasonably formed or the notch can be abandoned to be formed to meet the requirement of timely rotating the clamping clamp 203 according to the valve body 3 with different shapes; and when the distance between the rotation centers of the valve body 3 and the clamp 203 is smaller, the clamping force of the clamp 203 is larger, so that a reliable air tightness detection result can be generated.

Because the design takes the ball valve as an example target, the ball valve is a representative of a rotary valve, the rotation range of a valve core, namely the valve, is 0-90 degrees, and a common manual reversing valve also has a similar principle, namely the valve core is driven to move by stirring a handle, so that the flow direction and the flow rate of a medium are changed, the valve body 3 to be detected can be driven by driving the chute 505 by using the first motor 501 when the handle is stirred, when the valve body is a valve body of the manual reversing valve, the first motor 501 can be driven to rotate by controlling the telescopic cylinder to stretch, the handle can be driven to move in space by combining vertical movement and horizontal rotation movement, and when the chute 505 needs to pull the handle, a clamping block needs to be installed above the chute 505 which is originally in a U shape, thereby make spout 505 pass through the fixture block and to the pressure of handle pull down the handle smoothly, so can improve this design adaptation in the adaptability and the practical flexibility of multiple type valve body 3.
