Abstract
The invention discloses a train weighing valve contact rod comprising a contact rod body, a lift rod stroke groove, vent holes, hooking holes and a contact rod inner hole, wherein the contact rod body is cylindrical, the contact rod inner hole is formed in the upper end of the contact rod body, the lift rod stroke groove is formed in the lower end of the contact rod body, the contact rod inner hole and the lift rod stroke groove are concentric to the contact rod body, sealing cavities are formed in the middle parts of the contact rod inner hole and the lift rod stroke groove, a plurality of vent holes are uniformly arranged in the circumferential direction of the top end of the lift rod stroke groove, and a pair of symmetrical hooking holes are formed in the top end of the contact rod body. Due to the mode, the brake force of a train is adaptive to the bearing of the weighing valve by the train weighing valve contact rod, and the train weighing valve rod has the characteristics that the structure is simple, the manufacturing cost is low, the matching property is strong, the performance is stable, and the like.
Description
Technical field
The present invention relates to the controlling component technical field, particularly relate to a kind of train weighing valve feeler lever.
Background technique
Along with railway transport to high-speed overload require increasingly highly, 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 regulating device, makes the output signal pressure consistent with the load-carrying load.Existing weighing valve is because the design deficiency of feeler lever, the poor effect of often weighing, and poor stability, accuracy rate is not high, and error is big, and volume is big, manufacture cost is higher.
Summary of the invention
The technical problem that the present invention mainly solves is: the deficiency to existing technology, a kind of train weighing valve feeler lever is provided, and 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 technological scheme that the present invention adopts is: a kind of train weighing valve feeler lever is provided, comprises: feeler lever body, lift rod stroke groove, exhaust port, mount hole and feeler lever endoporus, and said feeler lever body is a cylindrical bar; Its upper end is provided with the feeler lever endoporus; The lower end is provided with the lift rod stroke groove, and said feeler lever endoporus and said lift rod stroke groove are all concentric with said feeler lever body, and the airtight cavity of middle formation; The top circumferencial direction of said lift rod stroke groove evenly is provided with the plurality of rows pore, and the top of said feeler lever body also has a symmetrically arranged mount hole.
In preferred embodiment of the present invention, the lower end of said feeler lever body further comprises a draw-in groove.
In preferred embodiment of the present invention, the quantity of said exhaust port is 4.
In preferred embodiment of the present invention, said feeler lever endoporus and said lift rod stroke groove all with the concentricity of said feeler lever body smaller or equal to 0.015mm.
In preferred embodiment of the present invention, the material of said train weighing valve feeler lever is the 10# seamless steel pipe.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of train weighing valve feeler lever; Adjust the size of air pressure through the exhaust port at lift rod stroke groove top, can eliminate the influence of the variation of load-carrying load the output signal pressure, make signal pressure more accurately, stable; Have simple in structure; Low cost of manufacture, matching is strong, and characteristics such as stable performance.
Description of drawings
Fig. 1 is the structural representation of train weighing valve feeler lever of the present invention one preferred embodiment;
The mark of each parts is following in the accompanying drawing: 1, feeler lever body, 2, the lift rod stroke groove, 3, exhaust port, 4, mount hole, 5, the feeler lever endoporus, 6, draw-in groove.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also shown in Figure 1ly, the embodiment of the invention comprises:
A kind of train weighing valve feeler lever, its material is the 10# seamless steel pipe.Comprise: feeler lever body 1, lift rod stroke groove 2, exhaust port 3, mount hole 4 and feeler lever endoporus 5; Said feeler lever body 1 is a cylindrical bar; Its upper end is provided with feeler lever endoporus 5, and the lower end is provided with lift rod stroke groove 2, and said feeler lever endoporus 5 and said lift rod stroke groove 2 are all concentric with said feeler lever body 1; And concentricity remains in the 0.015mm, guarantees the stability of product; Constitute airtight cavity in the middle of said feeler lever endoporus 5 and the said lift rod stroke groove 2.
In addition, the top circumferencial direction of said lift rod stroke groove 2 evenly is provided with plurality of rows pore 3, in the present embodiment; The quantity of exhaust port 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 exhaust port 3; Keep output signal pressure and load-carrying load consistent, make output signal air pressure more accurate.
The top of said feeler lever body 1 also has a symmetrically arranged mount hole 4, be used for weighing valve in miscellaneous part be connected.
The lower end of said feeler lever body 1 further comprises a draw-in groove 6, be used for equally with weighing valve in miscellaneous part be connected.
The present invention has disclosed a kind of train weighing valve feeler lever; Adjust the size of air pressure through the exhaust port at lift rod stroke groove top, can eliminate the influence of the variation of load-carrying load the output signal pressure, make signal pressure more accurately, stable; Have simple in structure; Low cost of manufacture, matching is strong, and characteristics such as stable performance.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; 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 invention.
