Abstract
The utility model relates to a novel disengaging-resistant screw joint flexible ball-body rubber joint for an internal combustion locomotive. A matching groove is arranged at the inner side of both ends of the rubber joint, which is matched with a projection of a screw connection metal fastener along a circumferential direction on the basis of a flexible ball-body rubber joint structure for the screw connection of the internal combustion locomotive. A steel wire ring is pre-buried in the rubber which is arranged at both ends of the rubber joint and is matched with an outer edge of the groove. When the fastener is tightly locked, the flexible ball-body rubber joint is not easy to disengage in the use process. The utility model especially has obvious effects under the conditions of high temperature and pressure, drastic vibration, and big setting-up eccentricity.
Description
The internal combustion locomotive that the utility model relates to a kind of novel structure is with the anti-slip flexible spheroid elastomer connector (hereinafter to be referred as elastomer connector) that is threaded, and this elastomer connector is mainly used in the connection of pipelines such as internal combustion locomotive fuel oil, lubricant oil, cooling water.
This elastomer connector is to improve design at the shortcoming of original elastomer connector.At first structure and the brief introduction of work principle with elastomer connector is as follows: the concrete structure of original elastomer connector can be divided into two-part, and a part is the ball body portion, and another part assembles two-part during use for the metal fastener that is threaded.The design use principle of elastomer connector is such: the fuel oil of internal combustion locomotive, lubricant oil, when cooling water pipeline need connect, if directly adopt metal spiral shell button or flange mouth counterpart to connect, then require two sections pipelines that very high concentricity is arranged, otherwise can't install or cause bigger Installation Stress, when locomotive operation, vibration that vibration sources such as diesel engine produce and pulse meeting are shaken the metal welding seam of rigid flange connecting or spiral shell button and are split; Adopt elastomer connector, then can utilize the characteristics of the easy deformation of elastomer connector to solve the problem of pipeline setting-up eccentricity, utilize the elastomer connector sphere structure can be simultaneously in the characteristics of all directions distortion, absorb the vibration and the pulse of vibration source generations such as diesel engine, avoided above-mentioned vibration and pulse to be directly delivered on the pipeline, thereby improved the operational safety of pipe-line system, ensured the normal operation of locomotive.Yet; there is following shortcoming in present elastomer connector: rubber spheroid and metal fastener matching part are plane contact; radial deformation often can take place in the rubber spheroid under hydrodynamic pressure and locomotive vibration, rubber compresses slippage from the metal fastener and comes out, and causes escape of liquid.
The purpose of this utility model just provides a kind of internal combustion locomotive with the anti-slip flexible spheroid elastomer connector that is threaded, and solves internal combustion locomotive and now with elastomer connector the elastomer connector end compresses slippage from the metal fastener problem often takes place in use.
The design philosophy of this model utility is such: original elastomer connector end rubber is that plane type contacts with locking metal fastener, slippage easily under the effect of pressure and vibration, therefore along the circumferential direction design one in the inboard, two ends of elastomer connector with the boss mated position of the metal fastener that is threaded and cooperate groove, pre-buried steel wire ring in the rubber of cooperation groove outer, elastomer connector two ends.So in use, the radial deformation that the rubber spheroid takes place under hydrodynamic pressure and locomotive vibration is subjected to being matched with the boss restriction of the metal fastener that is threaded of groove, unless locking position rubber destroys, causes leakage otherwise be difficult to take place slippage.
The utility model is realized by the following method.Along the circumferential direction design one at the ball end of body and cooperate groove, the specification that the degree of depth of groove can be different according to elastomer connector designs the different degree of depth; At the inner pre-buried steel traveler of groove outer rubber, during the production elastomer connector, steel traveler is integral as the cord parcel of framework material and with the vulcanization of rubber in the elastomer connector.The thickness of steel traveler, girth can be selected different sizes according to the different size of elastomer connector.Steel traveler does not expose.
The utlity model has following advantage, reasonable in design, good seal performance, especially under hydrodynamic pressure height, vibration is violent, setting-up eccentricity is big situation, can slippage, safe and reliable.
Below in conjunction with accompanying drawing embodiment of the present utility model is done further detailed description.
Fig. 1 is original elastomer connector overall structure generalized section.
Fig. 2 is the utility model overall structure generalized section.
Fig. 3 is original elastomer connector ball body portion generalized section.
Fig. 4 is the utility model ball body portion generalized section.
By Fig. 1 and Fig. 2 as can be seen, original elastomer connector and the utility model internal combustion locomotive can be subdued the spheroid elastomer connector and all are made up of metal fastener 1 and rubber spheroid 2 two-part with anti-slip being threaded.Wherein the metal fastener is divided into three parts again, and pipeline fastener 3 directly links to each other with metal tubes, and rubber fastener 4 should be assembled in the two ends of rubber spheroid 2 in advance, and lock fastener 5 is responsible in installation process pipeline fastener 3 and 4 lockings of rubber fastener.By the contrast of Fig. 3 and Fig. 4 as can be seen, originally the spheroid end face of elastomer connector is the plane, in use come out from the fastening slippage easily, and the utility model rubber spheroid end face is provided with cooperation groove 9, and along the circumferential direction be provided with steel traveler 6, cord 7 packs tightly steel traveler and is sulfided into the rubber spheroid with rubber 8.In addition, rubber fastener 4 is designed to the boss form among Fig. 2, so that cooperate with groove.These improve and have improved the anti-slip performance of elastomer connector greatly.For example, original elastomer connector of latus rectum Φ 40mm specification is adopted in the connection of DF8, DF11 type locomotive lubricating oil pipeline, when test pressure reaches 1.8～2.0MPa, slip phenomenon has taken place; And the utility model product of employing same specification, test pressure reaches 7.5MPa, ball body portion generation explosion, but slippage does not take place in the locking position.
