Abstract
The utility model discloses a high pressure falling-off preventing fast soft pipe joint, which comprises a truncated cone shaped core body (1); the big end of the truncated cone shaped core body (1) is jointed with a threaded connecting body (2); the other end of the threaded connecting body (2) is connected with a threaded connecting member (3); a locking sleeve (4) is arranged outside the truncated cone shaped core body (1); the front end of the locking sleeve (4) is a nut (5) matching the threaded connecting body (2); the rest space in the inner cavity of the locking sleeve (4) is flexiblepipe placing cavity (6); and the diameter of the nut (5) is smaller than the diameter of flexible pipe placing cavity (6). The soft pipe joint of the utility model achieves simple structure and good sealing performance; can be jointed up quickly; will not fall off or burst under high pressure (40 kilogram force); and can save energy and is beneficial to environmental protection.
Description
Technical field:
The utility model relates to a kind of hose coupling, especially a kind of simple in structure, good airproof performance, can connect fast and under high pressure (40 kgf) condition, also can not come off, the high pressure shed preventing quick hose joint of phenomenon such as explosion.
Background technique:
In fields such as industrial production, buildings, often need flexible pipe to be connected with valve, hard tube etc. with flexible pipe butt joint and flexible pipe.Clip is fixed in most at present still employing or iron wire is wrapped in the outer Placement of flexible pipe, exists following shortcoming:
1. sealing is poor.Clip and iron wire all can not guarantee sealability, and the dielectric leakage phenomenon often takes place, and not only waste energy, the cost of production that adds large enterprises, main is if what leaked is hazmat, then can cause environmental pollution, and people's healthy even life is all brought threat.
2. poor stability.It is firm that clip and iron wire can not guarantee to connect, when institute's fed sheet of a media overpressure just the phenomenon that flexible pipe comes off might take place, in addition, because clip and iron wire are to the active force inequality of flexible pipe, therefore joint flexible pipe explosion under high pressure also often taking place, brings than leaking more serious consequence.
3. flexible pipe serious waste phenomenon.Flexible pipe is under the unbalanced force effect of clip and iron wire, and the part denaturalization phenomenon will take place and cisco unity malfunction in the short period, and all need the flexible pipe that connecting end is rotten (700～800mm) clip and reinstall serious waste phenomenon more at every turn.
4. trouble is installed, wastes time and energy.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, a kind of simple in structure, good airproof performance is provided, can connect fast and under high pressure (40 kgf) condition, also can not come off, the high pressure shed preventing quick hose joint of phenomenon such as explosion.
Technical solution of the present utility model is: a kind of high pressure shed preventing quick hose joint, be provided with round table-like core body 1, the big end of round table-like core body 1 diameter be threaded 2 coaxial joining of body, the other end and the threaded connector 3 of the body 2 that is threaded join; Be with lock sleeve 4 outside round table-like core body 1, lock sleeve 4 front ends are the nut 5 that is complementary with the body 2 that is threaded, and lock sleeve 4 inner chamber remaining parts are that flexible pipe is inserted chamber 6, and the diameter of nut 5 is inserted the diameter in chamber 6 less than flexible pipe.
The outside of described round table-like core body 1 is provided with anti-skidding line 7.
The sidewall of inserting chamber 5 at the outside and the flexible pipe of described round table-like core body 1 is provided with a plurality of one sides for facing directly, and another side is the slideproof tooth 8 on inclined-plane.
The utility model is simple in structure, cost is low, being positioned at flexible pipe inserts the flexible pipe in chamber and will be subjected to uniform wedge shape power and radial force effect with tightening gradually of the body that is threaded along with nut, thereby stably be fixed between round table-like core body and the lock sleeve, can realize being connected with the flexible pipe butt joint and with valve, hard tube etc. by set threaded connector.Compared with prior art have following advantage:
1. good airproof performance, can prevent dielectric leakage, not only can save the energy, reduce the cost of production of enterprise, and can effectively avoid the leakage of hazmat, overcome environmental pollution that prior art causes because of leakage and to people's healthy, threat that lives and properties brought.
2. Security is good, because round table-like core body and lock sleeve are to the active force of flexible pipe evenly and dispersion, it is firm to guarantee to connect, even when institute's fed sheet of a media pressure is high pressure (40 kgf), can not take place also that flexible pipe comes off, the phenomenon of explosion, and is safe and reliable.
3. even because of the suffered pressure of flexible pipe, even long-time the use the local metamorphism phenomenon can not take place yet, saved the use amount of flexible pipe, further reduced the cost of production of enterprise, making the whole production cost is 70% of prior art;
4. install simply, time saving and energy saving, can increase work efficiency reaches 70%.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the utility model embodiment's a connection diagram.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.The utility model embodiment is as shown in Figure 1: be provided with round table-like core body 1, the big end of round table-like core body 1 diameter be threaded 2 coaxial joining of body, can make integrative-structure, the other end of the body 2 that is threaded joins with outside thread or internal thread link 3, also can be the integrative-structure form; Be with lock sleeve 4 outside round table-like core body 1, lock sleeve 4 front ends (near being threaded body 2 one ends) are the nut 5 that is complementary with the body 2 that is threaded, and lock sleeve 4 inner chamber remaining parts are that flexible pipe is inserted chamber 6, and the diameter of nut 5 is inserted the diameter in chamber 6 less than flexible pipe.All available corrosion-resistant, the anti-burst of each component can be made by good metal.In order to strengthen the frictional force between flexible pipe and round table-like core body 1 and the lock sleeve 4, can be provided with anti-skidding line 7 in the outside of round table-like core body 1, and being provided with a plurality of one sides for facing directly at the sidewall that the outside and the flexible pipe of described round table-like core body 1 are inserted chamber 5, another side is the slideproof tooth 8 on inclined-plane.
During use, the flexible pipe termination cut stretch into flexible pipe after flat and insert in the chamber 6, the front end of flexible pipe should be positioned at the boundary that nut 5 and flexible pipe are inserted chamber 6, round table-like core body 1 and flexible pipe are inserted the gap between the chamber 6, should mate with the wall thickness of flexible pipe, flexible pipe is then along with nut 5 is subjected to uniform wedge shape power and radial force effect with being threaded tightening gradually of body 2, thereby stably be fixed between round table-like core body 1 and the lock sleeve 4, can realization and being tightly connected of valve, hard tube etc. by set threaded connector 3 grades.
When flexible pipe docked, can be as shown in Figure 2: i.e. a pair of hose coupling that is complementary for threaded connector 3 of the utility model embodiment, as long as earlier flexible pipe is fixed between round table-like core body 1 and the lock sleeve 4, the threaded connector 3 that will be complementary again be tightly connected and gets final product.
