Description
Technical field
The utility model relates to field of sealing technology, is specifically related to a kind of magnetic force pressure relief device.
Background technique
Plastic pipe refers to the common name of the pipe made with plastic material.Plastic pipe has from heavy and light, corrosion-resistant, and compressive strength is high, safe and sanitary, and resistance to water-flow is little, saves the energy, and save metal, better people's living environment, long service life, the features such as safe ready, are subject to the favor of pipework circle.Nearly 10 years, under the pulling of China's Macroscopic rapid economic development, under the background that China's plastic pipe develops on a large scale at chemical building material, experiencing high speed development.The same with all pipelines closed, plastic cement pipeline can cause some position excessive and damaged because bearing pressure because of tube wall unbalance stress equally, therefore, in order to safeguard the normal operation of pipeline, frequently must carry out pressure release to pipeline.
Because existing magnetic force pressure relief device majority is all realized by electromagnet, magnetic force pressure relief device generally comprises coil, slip electromagnet, fixed electromagnet, sliding piston, sealing block, Returnning spring and fixed contact, the lighting outlet of coil respectively with another Electrode connection of fixed contact and power supply, form a complete working circuit, by controlling the magnetic force of electromagnet to the energising of coil and power-off and then control sealing block to the sealing of pipeline and dredging.Use the dependence of the magnetic force pressure relief device of electromagnet to electric power and electric accumulator large, and complex structure, price is more expensive, is not easy to promote the use of in poverty-stricken area.
Model utility content
In order to overcome the said goods produced problem, the utility model provides one not rely on electric power and low-cost a kind of magnetic force pressure relief device.
The technological scheme adopted to realize the purpose of this utility model is: a kind of magnetic force pressure relief device, comprise pipe cap, body, the first magnet, the second magnet and annular boss, described pipe cap is the round tubular structure that one end is closed, first magnet is located on the inner roof wall of pipe cap, and the inwall of pipe cap is provided with screw thread; Described body is round tubular structure, the tube wall outer wall at body two ends is respectively equipped with top screw thread and lower thread, the outer side wall of annular boss is fixed on the madial wall of body, second magnet is placed on endoporus annular boss also covering completely annular boss, the sidewall of body has the discharge orifice with extraneous conducting, discharge orifice is positioned at the top of the second magnet; The top screw thread of body is threaded with pipe cap, and the opposing side of the first magnet and the second magnet is same magnetic pole.
Top as referred to herein screw thread refers to the outside thread that body is connected with pipe cap, lower thread vial body and the outside thread needing the pipeline protected to be connected.The top of the second magnet refers to away from the second magnet, near the space of top screw thread.
Working principle of the present utility model: during use, is first threaded the lower thread on body with needing the pipe-line system protected.Again pipe cap is threaded with body, when pipe cap is connected with body, because the opposing side of the first magnet and the second magnet is same magnetic pole, utilize the natural phenomenon of magnet homopolar-repulsion, second magnet is subject to the magnetic force that the first magnet gives, and the second magnet and annular boss fit tightly, and covers the endoporus of annular boss completely, inside and outside isolated pipeline, make it to the liquid in pipeline or confined gas.By the distance regulating the distance be threaded of pipe cap and body to regulate the first magnet and the second magnet, and then regulate the size of magnetic force, stop regulating when magnetic force is equal with the pressure of protected pipeline, the pressure balance now in the magnetic force of magnet and pipeline.When manifold pressure is excessive; liquid in pipeline or gas can upwardly move upward by the second magnet; the second magnet is made to leave annular boss; expose the discharge orifice be blocked; liquid in protected pipeline or gas outwards influx discharge orifice from the space between the second magnet and annular boss, are flowed out by discharge orifice.When the liquid in pipeline or gas flow out a certain amount of after, the pressure in pipeline declines gradually until return to pressure in original pipe.Second magnet is because of the Distance Shortened with the first magnet, magnetic force is between the two caused to become large, in pipeline drops process in, second magnet also falls back to gradually on annular boss under magnetic force, until pressure reaches balance again in the magnetic force of the second magnet and pipeline, second magnet is close to annular boss again, and the second magnet covers the endoporus of annular boss completely, seals pipeline.
Compared with prior art, the beneficial effects of the utility model: 1, directly controlled the pressure in pipeline by the interaction force between the first magnet and the second magnet two block permanent magnet, avoid the dependence to electric power and electric accumulator.2, the utility model only comprises pipe cap, body, the first magnet and the second magnet, and structure is simple, and materials are common, low price, easy to operate, is easy to promote.
Further, described pipe cap and body are plastics, Moisture-proof corrosion-proof.
Further, described first magnet is the round sheet magnet mated with pipe cap inscribed circle size, described second magnet is the round sheet magnet mated with body inscribed circle size, first magnet and the second magnet are the round sheet magnet mated with tube wall inscribed circle size, be provided with in limited space maximum area and can the magnet of easy motion up and down.
Further, described first magnet and the second magnet are all wrapped in one deck rubber outward, intercept the first magnet and the second magnet and contacting external air, prevent magnet to be corroded, and magnetic declines.
Further, described pipe cap is provided with limited ring, and limited ring and the first magnet are close to, and are firmly fixed in pipe cap by the first magnet.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of the utility model embodiment.
In figure, reference character is: 1-pipe cap, 2-limited ring, 3-first magnet, 4-body, 5-top screw thread, 6-lower thread, 7-annular boss, 8-discharge orifice, 9-second magnet.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of magnetic force pressure relief device, comprise pipe cap 1, body 4, first magnet 3 and the second magnet 9, the round tubular structure that pipe cap 1 is closed for one end, limited ring 2 is provided with in pipe cap 1, inlay the first magnet 3, first magnet 3 in limited ring 2 and be close to pipe cap 1 roof, in the tube wall of pipe cap 1, be provided with screw thread; Body 4 is round tubular structure, top screw thread 5 and lower thread 6 is respectively equipped with outside the tube wall at body 4 two ends, horizontal annular boss 7 is provided with in body 4, second magnet 9 is placed on to seal on annular boss 7 and with annular boss 7 and fits, and the tube wall of the body 4 above the second magnet 9 has discharge orifice 8; The top screw thread 5 of body 4 is threaded with pipe cap 1, and the opposing side of the first magnet 3 and the second magnet 9 is same magnetic pole.
