Abstract
The utility model relates to a measuring device of valve stroke, comprising a valve, wherein the valve is arranged in a valve spring seat, and a mounting frame is arranged at one side above the valve spring seat, a displacement sensor is arranged in the mounting frame through a regulating nut and is connected with a data processing device via a line. The valve spring seat of the measuring device moves with the valve, the distance between the displacement sensor and the valve spring seat can be sensed by the displacement sensor, thus the distance is converted into the valve stroke, the regulating nut can regulate a gap between the displacement sensor and the valve spring seat to obtain an initial distance between the displacement sensor and the valve spring seat. The measuring device of valve stroke can be used for measuring the stroke of an exhaust valve when an engine is braked, and can provide theoretical basis for solving the faults that the head part of the exhaust valve is broken due to the separation of the exhaust valve when the engine is braked and like, improving a valve actuating mechanism and a brake structure. The utility model has the advantages of simple structure, low cost, convenience and practicability, and suitability for popularization and application.
Description
Technical field
The utility model relates to a kind of measurement mechanism, especially a kind of valve stroke measurement mechanism.
Background technology
When using engine braking, back pressure can raise rapidly in the gas outlet, the pressure differential of exhaust valve both sides can be very big, this can cause very big exhaust valve to fly off and more fierce bump when taking a seat, cause faults such as exhaust valve head fracture, exhaust valve travel when measuring engine braking can be when solving engine braking flies off the faults such as exhaust valve head fracture that cause, improves valve actuating mechanism and brake structural provides theoretical foundation because of exhaust valve.But also there is not similar measurement mechanism at present.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, cost is low, it is convenient to measure, exhaust valve travel in the time of can measuring engine braking can be when solving engine braking flies off the faults such as exhaust valve head fracture that cause, improves the valve stroke measurement mechanism that valve actuating mechanism and brake structural provide theoretical foundation because of exhaust valve.
For achieving the above object, the utility model adopts following technical proposals:
A kind of valve stroke measurement mechanism, comprise valve, described valve is arranged in the cotter seat, and cotter seat top one side is provided with mounting bracket, be provided with displacement transducer by setting nut in the mounting bracket, displacement transducer links to each other with data processing equipment by circuit.
Data processing equipment in the utility model is an existing equipment, does not repeat them here.
Cotter seat of the present utility model moves with valve, by displacement transducer can inductive displacement pick-up and cotter seat between distance, thereby the valve stroke of converting to, and setting nut can be regulated the gap of displacement transducer and cotter seat, obtains the initial distance between displacement transducer and the cotter seat.Exhaust valve travel when this valve stroke measurement mechanism can be measured engine braking provides theoretical foundation because of exhaust valve flies off the faults such as exhaust valve head fracture, improvement valve actuating mechanism and the brake structural that cause during for the solution engine braking.The utility model is simple in structure, with low cost, convenient and practical, suitable to be applied.
