Description
Technical field
The utility model relates to cylinder fuel feeding valve group, especially a kind of big-block engine cylinder grease gun oil nozzle valve group peculiar to vessel.
Background technique
The fuel system of high-power low-speed diesel engine cylinder lubrication, is originally mechanical lubricator fuel feeding; Mechanical lubricator is with main frame interlock, is often given to oil once, causes that fuel consumption is large, cost is high, seriously polluted.In addition, the oiling frequency of mechanical type oil gun is directly proportional to engine speed, and the load of diesel main engine, be directly proportional to the cube of rotating speed.Therefore, mechanical type oil gun can not realize accurate oiling at regular time and quantity according to the change of power.
And some diesel engine adopts automatically controlled injection system now, automatically controlled injection system better can substitute mechanical lubricator fuel feeding, realizes the oiling that accurate timing is quantitative.But automatically controlled injection system system down or break down sometimes, easily damages main frame, causes very serious consequence, affect the normal use of motor.
Therefore, above-mentioned technical problem is necessary to propose relevant improvement.
Model utility content
For the deficiency that prior art exists, it is simple, easy to use that the utility model provides a kind of structure, can realize machinery and automatically controlled two-way fuel feeding respectively, more safe and reliable one big-block engine cylinder peculiar to vessel grease gun oil nozzle valve group.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of big-block engine cylinder grease gun oil nozzle valve group peculiar to vessel, it comprises valve body, described valve body left surface is provided with electric pouring orifice, described valve body lower end face arranges organic pouring orifice, described valve body upper-end surface is partial to left part and is provided with the first one-way valve, described valve body right flank is provided with the second one-way valve, and described valve body front-end face is provided with oil outlet; Described electric pouring orifice is communicated with oil outlet by the first one-way valve, and described machine pouring orifice is communicated with oil outlet by the second one-way valve.
Preferably, described valve body upper-end surface is partial to right part and is connected with accumulator, and the asphalt channel mouth of described accumulator is arranged between machine pouring orifice and the second one-way valve.
Preferably, be partial to lower portion and be provided with pressure tap on the right side of described valve body, the asphalt channel mouth of described pressure tap is arranged between machine pouring orifice and accumulator asphalt channel mouth.
Preferably, described first one-way valve and the second one-way valve all adopt plug-in one-way valve.
Owing to adopting technique scheme, this practicality adopts two pouring orifices, can achieve machine control oiling and automatically controlled oiling and coordinate and run, as one of them injection system breaks down another can cooperating, considerably increase the safe and reliable of oiling like this, decrease engine failure rate; Also be provided with accumulator and pressure-measuring pipe in addition, accumulator can ensure that oil pressure is normal, and pressure-measuring pipe is connected with outside pressure instrumentataion, can periodic monitor oil pressure, while simple and compact for structure, there is very strong practicability.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As Fig. 1 and shown in composition graphs 2 and Fig. 3, a kind of big-block engine cylinder grease gun oil nozzle valve group peculiar to vessel, it comprises valve body 1, and valve body 1 left surface is provided with electric pouring orifice 4, and electric pouring orifice 4 is arranged on side, is convenient to stringing.Valve body 1 lower end surface arranges organic pouring orifice 6, and valve body 1 upper-end surface is partial to left part and is provided with the first one-way valve 2, and valve body 1 right flank is provided with the second one-way valve 5, and valve body 1 front-end face is provided with oil outlet 8; Electricity pouring orifice 4 is communicated with oil outlet 8 by the first one-way valve 2, and during automatically controlled oiling, fluid flows to motor through the first one-way valve 2 by oil outlet 8 from electric pouring orifice 4; Machine pouring orifice 6 is communicated with oil outlet 8 by the second one-way valve 5, and during machine control oiling, fluid flows to motor through the second one-way valve 5 by oil outlet 8 from machine pouring orifice 6, lubricates motor.
Fluid can not be flowed out from machine pouring orifice 6 by the second one-way valve 5 under the non-return effect of the second one-way valve 5 when wherein the first one-way valve 2 and the second one-way valve 5 have one-way flow function (can only flow to the other end from one end) automatically controlled oiling, can only flow out from oil outlet 8; Fluid can not be flowed out from electric pouring orifice 4 by the first one-way valve 2 under the non-return effect of the first one-way valve 2 during machine control oiling, can only flow out from oil outlet 8, therefore automatically controlled oiling and machine control oiling have separate and also have the effect cooperatively interacted, as machine control oiling can be adopted when automatically controlled injection system breaks down, when event appears in machine control injection system, automatically controlled oiling can be adopted.Do not need to change valve group in this process, greatly increase the incidence rate improving engine operating efficiency and reduce fault.And automatically controlled oiling is controlled by computer or electric control system, so accurate oiling at regular time and quantity can be carried out to fluid, improve engine lubrication effect.
Further, valve body 1 upper-end surface is partial to right part and is connected with accumulator 3, and the asphalt channel mouth of accumulator 3 is arranged between machine pouring orifice 6 and the second one-way valve 5.Because fluid is incompressible liquid, therefore utilize fluid to accumulate pressure energy, other media must be relied on change, accumulate pressure energy, accumulator is then adopted to carry out control valve group pressure, when pressure raises, fluid enters accumulator 3, and gas is compressed, and system line pressures no longer rises; When loine pressure declines, pressurized air expands, and fluid is pressed into loop, thus slows down the decline of loine pressure.Accumulator 3 is arranged between machine pouring orifice 6 and the second one-way valve 5, and because machine control oiling utilizes mechanical external force to carry governor pressure, mechanical external force is unstable, time height time low, then need accumulator 3 to carry out adjustment pressure.And automatically controlled oiling utilizes electric automatic control, whether about pressure all comes by setting value, so pressure is relatively stable, does not then need accumulator to carry out pressure adjustment.
Further, be partial to lower portion and be provided with pressure tap 7 on the right side of valve body 1, the asphalt channel mouth of pressure tap 7 is arranged between machine pouring orifice 6 and accumulator 3 asphalt channel mouth.Because machine control oiling can not measure oil liquid pressure, then need external measurement devices to measure, therefore need to arrange pressure tap 7 between machine pouring orifice 6 and accumulator 3, pressure tap 7 is connected with outside pressure instrumentataion, can measure oil pressure in a situation of use where; And automatically controlled oiling utilizes electrical control, whether about pressure can be measured by electric control system, then do not need separately to arrange pressure tap 7.
Further, the first one-way valve 2 and the second one-way valve 5 all adopt plug-in one-way valve, and valve opening profile cutter is processed, and seals reliable and stable.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
