Embodiment
In order to make those skilled in the art understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1-Fig. 8, the structural representation of the silk braid nut that Fig. 1 embodiment of the present invention provides; The silk braid nut that Fig. 2 embodiment of the present invention provides and stop ring and baffle ring with the use of structural representation; The sectional structure schematic diagram of the silk braid nut that Fig. 3 embodiment of the present invention provides; The structural representation of the baffle ring that Fig. 4 embodiment of the present invention provides; The structural representation of the stop ring that Fig. 5 embodiment of the present invention provides; The structural representation overlooked of the stop ring that Fig. 6 embodiment of the present invention provides; The plan structure schematic diagram of the stop rod that Fig. 7 embodiment of the present invention provides; The structural representation of the expansion valve that Fig. 8 embodiment of the present invention provides.
The expansion valve that the embodiment of the present invention provides, comprise baffle ring 3, stop ring 2, needle, valve needle cover and silk braid nut 1, guiding endoporus is provided with in silk braid nut 1, needle is arranged in valve needle cover, valve needle cover is arranged in guiding endoporus, silk braid nut 1 is plastic material, the outer wall of silk braid nut 1 is provided with the outside thread 101 as guide rail, expansion valve provided by the invention product structure more of the prior art is simple, stop ring about 2 stop and running noises little, component function modoularization, effectively decrease amount of parts, eliminate multiple tracks assembling and welding process, greatly reduce product cost, and by adopting the silk braid nut 1 of plastic material, and on the outer wall of silk braid nut 1, inject outside thread 101 use, noise can be reduced.
In order to optimize such scheme further, outside thread 101 comprises stop ring guide rail and is positioned at the lower stop ledge 102 of the end below stop ring guide rail, the upper surface of silk braid nut 1 is provided with head recess 103, the top of baffle ring 3 is stuck in head recess 103, stop ring 2 is arranged on stop ring guide rail, the top of stop ring 2 is provided with overhanging upper straight rod section 201, be connected by upper elbow section 202 between upper straight rod section 201 and the ring body of stop ring 2, the end of stop ring 2 is provided with overhanging lower straight bar section 203, be connected by lower elbow section 204 between lower straight bar section 203 and the ring body of stop ring 2, upper straight rod section 201 and lower straight bar section 203 all with the stop rod 4 on rotor housing 5 with the use of, the end of baffle ring 3 block elbow section 202 with the use of, lower elbow section 204 and lower stop ledge 102 with the use of.
When completing spacing action, comprise two kinds of arrested states: lower arrested state: the lower stop ledge 102 on silk braid nut 1 blocks the descending thread groove of outside thread 101, lower straight bar section 203 is stirred in stop rod 4 dextrorotation, and lower elbow section 204 is by lower stop ledge 102 backstop; Upper arrested state: form screw-in buckle structure between the top of baffle ring 3 and head recess 103 and block, the function of the anti-rotational axle vibration of circumferencial direction can be played after screw-in, the end of baffle ring 3 blocks the up thread groove of outside thread 101, upper straight rod section 201 is stirred in stop rod 4 dextrorotation, and upper elbow section 202 is by the end stop of baffle ring 3;
In order to optimize such scheme further, distance L1≤the L-R of the bottom of head recess 103 and the thread center of outside thread 101, the half of degree of depth L2 >=baffle ring 3 string diameter of head recess 103, L is pitch, and R is the circular arc tooth radius of outside thread 101, prevent the head recess 103 of the top dieback plastic material of baffle ring 3, cause leading screw to rotate, cause the stuck inefficacy of valve body, avoid that groove depth is too little causes baffle ring 3 situation out simultaneously, prevent from causing stop to lose efficacy, thus avoid valve body to lose efficacy.
In order to optimize such scheme further, the top of baffle ring 3 is provided with straight-bar 301, and the deformability of straight-bar 301 is not less than L2.Namely this straight-bar 301 stretches after L2 distance and can return to original form when not stressing, and use spring to be plant stop configurations thus to determine as baffle ring material, this structure needs screw-in one whirling body, namely screws in silk braid nut groove, avoids can not revolving out.
In order to optimize such scheme further, the bottom of head recess 103 is curve bath or straight trough, and using effect is better, and head recess 103 both can be penetrating with the inner core of silk braid nut 1, also can not be penetrating.
In order to optimize such scheme further, upper straight rod section 201 and lower straight bar section 203 are all perpendicular to the central axis of silk braid nut 1, and angle C is between the two not more than the center included angle A of stop rod 4.As shown in figures 6 and 7, when preventing dress magnetic core, the backstop boss of magnetic core inside is inserted in the middle of baffle ring 3 two heads, causes umber of pulse incorrect.
In order to optimize such scheme further, stop rod 4 is magnetic stop rod, concrete, and stop rod 4 can be integrated molding and forming with rotor housing 5, and stop rod 4 can for being arranged on boss or the groove of one or more backstop on rotor housing 5.
Apply specific case herein to set forth principle of the present invention and mode of execution, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
