Description

Detachable one-way drainage device used on engine or crankcase

Technical Field

The utility model relates to a crankcase technical field specifically is a can dismantle one-way drainage device for on engine or the crankcase.

Background

The charge air cooler is an important component of the supercharging system for the engine and the crankcase. In both the mechanical supercharged engine and the turbo supercharged engine, an intercooler is required to be arranged between a supercharger and an engine air inlet pipe, and the intercooler is used for cooling high-temperature air discharged from the supercharger to about 49 ℃. When the marine auxiliary engine is used in a low load, the air inflow of the engine is small, a sea water pump which is responsible for supplying cooling for the intercooler also operates according to the original rated rotating speed, and cooling water is supplied to the intercooler according to the original rated flow and lift. Part of the condensed water enters the cylinder under the action of the pressurized airflow to influence the combustion effect of the fuel oil, so that the performance of the engine is poor, and part of the condensed water enters the crankcase to influence the operation of a crankshaft in the crankcase. And most parts of the piston are also provided with an intercooler air outlet pipe or an engine air inlet pipe, and water enters the cylinder when the piston is stopped, so that the water is accumulated at the top of the piston, the effective volume of a combustion chamber is reduced, the compression resistance is increased, and the pressure transmitted to the connecting rod by the piston is also increased. When the accumulated water amount reaches a certain degree (such as approaching the volume of a combustion chamber), the compression stroke is actually changed into the compression of water, the pressure born by the connecting rod is increased rapidly so as to generate bending deformation and even fracture, and thus the major accident of breaking the engine body occurs, so that the accumulated water in the engine and the crankcase needs to be discharged, and the running stability is ensured.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide a can dismantle one-way drainage device for on engine or the crankcase, collect the comdenstion water that the intercooler produced, discharge when accumulating a certain amount, guaranteed the performance of engine, can effectively solve the problem in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a can dismantle one-way drainage device for on engine or crankcase, includes the shell, the top of shell is provided with the water inlet, and the water inlet is connected with the outlet duct of intercooler, and the lower part of shell is provided with the outlet, and the outlet top is provided with the stagnant water chamber, and the inside of shell is provided with the float, and the top of float is provided with the spring, and the inner wall top at the shell is supported on the top of spring, and the lower extreme of float is provided with the end cap, and the end cap is located the stagnant water intracavity.

As an optimized technical scheme of the utility model, be provided with the check valve in the water inlet.

As a preferred technical scheme of the utility model, end cap and stagnant water chamber are big-end-up's toper and tapering the same.

As an optimized technical scheme of the utility model, the lateral surface of end cap is provided with the ring channel, and the ring channel endotheca is equipped with the sealing ring.

As an optimized technical scheme of the utility model, the outside parcel of spring has the protection gum cover.

As a preferred technical scheme of the utility model, the float is cylindrical, and the outside slidable ground cover of float is equipped with the retaining ring, and the retaining ring passes through the connecting rod to be fixed in the inside of shell.

Compared with the prior art, the beneficial effects of the utility model are that: the detachable one-way drainage device for the engine or the crankcase collects condensed water generated by the intercooler, and the condensed water is discharged when accumulated to a certain amount, so that the performance of the engine is ensured, the reliability of the engine and the crankcase is improved, and faults caused by a large amount of deposited condensed water are reduced.
