The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1, the embodiment of the present application provides a steel cylinder hydrostatic test screw adapter, which includes a main body portion 1, where the main body portion 1 is provided with a water flow channel 11 penetrating through the main body portion 1; the two ends of the water flow channel 11 are both provided with a thread structure 12, the thread structure 12 at one end is in threaded connection with the water filling pipe 2, and the thread structure 12 at the other end is in threaded connection with the opening of the steel cylinder 3; the flange structure 16 is arranged on the outer side of the main body part 1, and the flange structure 16 of the main body part 1 is fixed at the center of the water jacket cover plate 4 through a threaded fastener.
The 3 hydrostatic test screw thread adapter of steel bottle that this embodiment provided, through set up rivers passageway 11 on 3 hydrostatic test screw thread adapter's of steel bottle main part 1, and set up the helicitic texture 12 that is used for connecting steel bottle 3 and water filling pipe 2 respectively at rivers passageway 11 both ends, and set up flange structure 16 and adopt threaded fastener to fix threaded adapter (3 hydrostatic test screw thread adapter of steel bottle promptly) to water jacket apron 4, make when carrying out the hydrostatic test to different steel bottle 3, only need loosen threaded fastener and pull down original threaded adapter, can on installing suitable threaded adapter to water jacket apron 4. Because need not to carry out the dismouting to the water jacket apron 4 that weight is heavier, and the installation is complicated, and only need change different screw adapter can realize carrying out water pressure detection to the steel bottle 3 of different grade type, and then improved water pressure detection's efficiency to improve the production efficiency of steel bottle 3.
In addition, through adopting helicitic texture 12 to connect steel bottle 3 and fill water pipe 2, because threaded connection has good sealing performance and stability for 3 hydraulic test screw adapters of steel bottle have better sealing performance with the steel bottle 3 and fill the hookup location of water pipe 2, can ensure that phenomenons such as the pine takes off, leaks when carrying out the hydraulic test, and then ensured the accuracy of test result and the stability of testing process.
After the test is completed, before the screw adapter is detached from the steel cylinder 3, the water filling pipe 2 needs to be detached first, and before that, although a part of the high-pressure water in the steel cylinder 3 is discharged (discharged through the water filling pipe 2), there is still a risk that a worker detaches the water filling pipe 2 when the high-pressure water in the steel cylinder 3 is not completely discharged (for example, the worker does not notice that the water pressure value in the steel cylinder 3 is high and the water filling pipe 2 is detached from the screw adapter by an erroneous operation), so that the high-pressure water in the steel cylinder 3 is ejected upwards from the water flow channel 11 of the screw adapter, and the diameter of the water flow channel 11 is small, so that the flow rate of the ejected water is fast, and the high-speed ejected water easily causes a risk of injury to the worker (for example, the high-pressure water is ejected to cause injury to weak positions such as eyes of the worker).
For this reason, in one embodiment, the steel cylinder 3 hydraulic test screw adapter further includes a protection portion 13, the protection portion 13 is disposed in the water flow channel 11, and the protection portion 13 is used to prevent the high-pressure water in the steel cylinder 3 from being sprayed out from the water flow channel 11 after the water filling pipe 2 is detached from the main body 1, so as to prevent a worker from being injured due to the spraying of the high-pressure water from the water flow channel 11 caused by improper operation.
In detail, the protection part 13 may include an elastic member 132 and a blocking block 131. The plugging block 131 comprises a spherical plug and a push-out rod arranged on the plug, the spherical plug is arranged in an arc-shaped inward-shrinkage area in the water flow channel 11, and the push-out rod extends into a threaded structure 12 area matched with the water filling pipe 2, so that after the water filling pipe 2 is matched into the water flow channel 11, the water filling pipe 2 pushes the push-out rod open, and the plug is away from the arc-shaped inward-shrinkage area in the water flow channel 11. One end of the elastic member 132 abuts against the inner wall of the water flow passage 11, the other end of the elastic member 132 abuts against the ball plug, and the elastic member 132 is in a compressed state.
When the screw adapter is used, as shown in fig. 5, after the water filling pipe 2 is fixed to the threaded structure 12 of the main body portion 1, the bottom of the water filling pipe 2 provides downward ejection force to the ejection rod, so that the plugging block 131 overcomes the elastic force of the elastic member 132 (which may be a spring, an elastic sheet, or the like) to move downward (towards the position of the steel cylinder 3), and further, the spherical plug is separated from the arc-shaped retraction area in the water flow channel 11, so that the whole water flow channel 11 is smooth, at this time, the water filling pipe 2 can inject water into the steel cylinder 3 through the water flow channel 11 to improve the water pressure in the steel cylinder 3 for inspection. After the inspection is completed, the high pressure water in the steel cylinder 3 can be returned to the water charging pipe 2 through the water flow passage 11 for pressure relief. If the water pressure in the steel cylinder 3 is not completely removed, and a worker mistakenly removes the water filling pipe 2, since the water filling pipe 2 is separated from the matching with the thread structure 12, at this time, the elastic force of the elastic member 132 gives the upward elastic force to the blocking block 131, so that the blocking block 131 is tightly attached to the arc-shaped inward-contracting area in the water flow channel 11, the water flow channel 11 is closed (as shown in fig. 2), and the high-pressure water in the steel cylinder 3 is prevented from being sprayed out at a high speed through the water flow channel 11 to cause injury to the worker.
The protection portion 13 of this embodiment may be different from a conventional check valve, and the protection portion 13 of this embodiment may open the water flow passage 11 when the water filling pipe 2 is mounted on the screw adapter, and may discharge the high pressure water in the steel cylinder 3 through the water flow passage 11 when pressure is released, and may close the water flow passage 11 only when the water filling pipe 2 is detached from the screw adapter, so as to prevent the high pressure water in the steel cylinder 3 from being discharged.
Optionally, the spherical plug of the plugging block 131 may have a double-layer structure, the inner layer of the spherical plug is made of a high-strength metal material (such as steel), and the outer layer of the spherical plug may be made of an elastic material (such as rubber), so that when the plugging block 131 blocks the arc-shaped retraction area in the water flow channel 11 under the elastic action of the elastic member 132, a better sealing effect is achieved.
As shown in fig. 3, in an embodiment, the hydraulic test screw adapter of the steel cylinder 3 further includes a plurality of buffer channels 14, a side of the water flow channel 11 close to the steel cylinder 3 is sealed, and the water flow channel 11 is communicated with the steel cylinder 3 through the buffer channels 14, the buffer channels 14 are curved, and an outlet of the buffer channels 14 communicated with the water flow channel 11 is disposed toward the steel cylinder 3.
Through setting up buffering passageway 14 for when steel bottle 3 carried out the release, the in-process that the water under high pressure in the steel bottle 3 flowed into water channel 11 through buffering passageway 14, crooked arc passageway can reduce the kinetic energy of rivers, and set up buffering passageway 14 and water channel 11 intercommunication export towards steel bottle 3 direction, make when rivers flow out to water channel 11 from buffering passageway 14, can take place the impact with the inner wall of water channel 11, further reduce the kinetic energy of rivers. To reduce the flow rate of the water flow of the cylinder 3 outwardly from the water flow passage 11.
In one embodiment, the buffer passages 14 are uniformly distributed on the main body 1, and the outlet direction of the buffer passages 14 communicated with the water flow passage 11 faces the center of the water flow passage 11. The outlet direction of the buffer channel 14 communicated with the water flow channel 11 is set to be towards the center of the water flow channel 11, so that the water flows output to the water flow channel 11 from different buffer channels 14 are impacted and collided with each other, and the kinetic energy of the water flow is further reduced (the kinetic energy of the water flow is converted into heat energy).
In one embodiment, steel balls 15 are disposed at the connection position of the water flow channel 11 and the buffer channel 14, and the outlets of the buffer channel 14 communicating with the water flow channel 11 are distributed around the steel balls 15 clockwise or counterclockwise. By arranging the steel ball 15, the water flow output from the buffer channel 14 to the water flow channel 11 impacts the steel ball 15, and under the impact force of the water flow, the steel ball 15 rotates and collides with the inner wall of the buffer channel 14 to generate friction and generate sound. At this time, the worker can judge whether the high-pressure water in the steel cylinder 3 is completely discharged according to whether the steel ball 15 makes a sound, the worker is aurally reminded of the pressure condition in the steel cylinder 3, and accidents caused by the fact that the water filling pipe 2 is detached in advance to cause the high-pressure water to be sprayed are avoided.
In one embodiment, the steel ball 15 is hollow inside, and the overall density of the steel ball 15 is greater than the density of water. By providing the steel ball 15 in a hollow shape, the sound of the collision friction between the steel ball 15 and the inner wall of the buffer passage 14 is made louder, so as to remind the worker of the state in the steel cylinder 3. And because the whole density of the steel ball 15 is greater than that of water, the steel ball 15 is always positioned at one end in the water flow channel 11 close to the steel cylinder 3, and the steel ball is not easy to float upwards to block the water flow channel 11, so that the high-pressure water in the steel cylinder 3 cannot be discharged into the water filling pipe 2 through the water flow channel 11.
In one embodiment, the steel balls 15 are made of a high strength and wear resistant material, and may be embodied as high manganese steel, chrome steel, or the like. The steel ball 15 is made of high-strength wear-resistant materials, so that the steel ball 15 is more wear-resistant, and the service life of the steel ball 15 is prolonged.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
