Abstract
The utility model discloses a train weighing valve feeler lever which comprises a feeler lever body, a pushing rod stroke groove, exhaust vents, a hanging connecting hole and a feeler lever inner hole. The feeler lever body is a cylindrical rod. The feeler lever inner hole is arranged in the upper end of the feeler lever body. The pushing rod stroke groove is arranged at the lower end of the feeler lever body. The feeler lever inner hole and the pushing rod stroke groove are both concentric with the feeler lever body, and a sealed cavity body is formed in the middle of the feeler lever. A plurality of exhaust vents are evenly arranged along the periphery direction of the top end of the pushing rod stroke groove. A hanging connecting hole which is arranged symmetrically is arranged in the top end of the feeler lever body. According to the train weighing valve feeler lever, the braking force of a train can be matched with load bearing of a weighing valve, and the train weighing valve feeler lever has the advantages of being simple in structure, low in manufacturing cost, strong in matching performance, stable in performance and the like.
Description
Technical field
The utility model relates to the function unit technical field, particularly relates to a kind of train weighing valve feeler lever.
Background technology
Along with railway transportation is more and more higher to the requirement of high-speed overload, therefore the requirement of weighing valve is also increased thereupon.At present, domestic train weighing valve is various informative, but the action principle of weighing valve is basic identical, all is the load-carrying load is directly changed into the pressure air signal, and is transferred to the weighing valve setting device, makes output signal pressure consistent with the load-carrying load.Existing weighing valve is because the design defect of feeler lever, the poor effect of often weighing, and poor stability, accuracy rate is not high, and error is large, and volume is large, manufacturing cost is higher.
The utility model content
The technical matters that the utility model mainly solves is: for the deficiencies in the prior art, provide a kind of train weighing valve feeler lever, can improve product accuracy rate and stability, strengthen matching, make the effect of weighing better.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of train weighing valve feeler lever is provided, comprise: the feeler lever body, the lift rod stroke groove, deflation hole, mount hole and feeler lever endoporus, described feeler lever body is cylindrical bar, its upper end is provided with the feeler lever endoporus, the lower end is provided with the lift rod stroke groove, described feeler lever endoporus and described lift rod stroke groove are all concentric with described feeler lever body, and middle formation airtight cavity, the top circumferencial direction of described lift rod stroke groove evenly is provided with some deflation holes, and the top of described feeler lever body also has a symmetrically arranged mount hole.
In preferred embodiment of the utility model, the lower end of described feeler lever body further comprises a draw-in groove.
In preferred embodiment of the utility model, the quantity of described deflation hole is 4.
In preferred embodiment of the utility model, described feeler lever endoporus and described lift rod stroke groove all with the concentricity of described feeler lever body less than or equal to 0.015mm.
In preferred embodiment of the utility model, the material of described train weighing valve feeler lever is the 10# solid drawn pipe.
The beneficial effects of the utility model are: the utility model has disclosed a kind of train weighing valve feeler lever, adjust the size of air pressure by the deflation hole at lift rod stroke groove top, can eliminate the variation of load-carrying load to the impact of output signal pressure, make signal pressure more accurate, stable, have simple in structure, low cost of manufacture, matching is strong, and the characteristics such as stable performance.
Description of drawings
Fig. 1 is the structural representation of the utility model train weighing valve feeler lever one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, feeler lever body, 2, the lift rod stroke groove, 3, deflation hole, 4, mount hole, 5, the feeler lever endoporus, 6, draw-in groove.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also shown in Figure 1ly, the utility model embodiment comprises:
A kind of train weighing valve feeler lever, its material is the 10# solid drawn pipe.Comprise: feeler lever body 1, lift rod stroke groove 2, deflation hole 3, mount hole 4 and feeler lever endoporus 5, described feeler lever body 1 is cylindrical bar, its upper end is provided with feeler lever endoporus 5, the lower end is provided with lift rod stroke groove 2, described feeler lever endoporus 5 and described lift rod stroke groove 2 are all concentric with described feeler lever body 1, and concentricity remains in the 0.015mm, guarantees the stability of product; Consist of airtight cavity in the middle of described feeler lever endoporus 5 and the described lift rod stroke groove 2.
In addition, the top circumferencial direction of described lift rod stroke groove 2 evenly is provided with some deflation holes 3, in the present embodiment, the quantity of deflation hole 3 is 4, when push rod was headed into by lift rod stroke groove 2, air pressure inside increased, and must inner air be discharged by deflation hole 3, keep output signal pressure consistent with the load-carrying load, make output signal air pressure more accurate.
The top of described feeler lever body 1 also has a symmetrically arranged mount hole 4, is used for being connected with miscellaneous part in the weighing valve.
The lower end of described feeler lever body 1 further comprises a draw-in groove 6, and same being used for is connected with miscellaneous part in the weighing valve.
The utility model has disclosed a kind of train weighing valve feeler lever, adjust the size of air pressure by the deflation hole at lift rod stroke groove top, can eliminate the variation of load-carrying load to the impact of output signal pressure, make signal pressure more accurate, stable, have simple in structure, low cost of manufacture, matching is strong, and the characteristics such as stable performance.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
