The utility model has the advantages of simple structure, rational design and strong practicability. The utility model controls exactly and is easy to use; in the meantime, the utility model has low error rate and does not consume motion, applicable for the engine oil decompression control of a plurality of single cylinder and multi cylinder diesel engines and gasoline engines.
Description
Technical field
The utility model belongs to diesel engine, petrol engine accessory, the valve means of when particularly pump is for the machine oil decompression motor being protected.
Background technique
Diesel engine, petrol engine are power with the fuel oil, in the working procedure, need machine oil constantly to give position fuel feeding such as casing wall, wheel shaft, bent axle, lubricate guaranteeing, machine oil must keep certain pumping pressure, otherwise because the not enough phenomenons such as scuffing of cylinder bore, excessively heated axle, tile kilning that produce of fuel feeding, thereby damage diesel engine or petrol engine.Now some diesel engine or petrol engine adopt bayonet gauge that pumping pressure is monitored, but often because of absent minded or react untimely, phenomenons such as machine oil decompression tile kilning, sticking cylinder still often occur.Some has installed the machine oil electronic alarm device on machine, but this kind mode circuit is prone to problem, the rate of fault height.
Summary of the invention
The purpose of this utility model is to provide a kind of machine oil o-volt protection valve that the fuel feeding of diesel engine, petrol engine is combined with the pumping pressure of machine oil.
The utility model is achieved in that
Machine oil o-volt protection valve mainly is made up of valve body, it is characterized in that: the inner chamber of valve body surrounds an enclosed cavity by last pad and following pad, vertically is provided with one and the close-fitting valve rod of cavity between last pad and following pad, has oil guide slot on the valve rod; Also be provided with the oil-feed mouth of pipe and the fuel-displaced mouth of pipe that communicate with enclosed cavity on the valve body, the oil-feed mouth of pipe and the fuel-displaced mouth of pipe cooperate with above-mentioned oil guide slot; Also be provided with a machine oil mouth of pipe in the lower end of valve body, this machine oil mouth of pipe is by the sealing of above-mentioned pad down, and valve rod is provided with Returnning spring.
After the utility model adopts said structure; when the pumping pressure of machine oil is reduced to setting value; valve rod moves down; automatically seal the fuel gallery; diesel engine, petrol engine are in time shut down under the situation of no fuel delivery; thereby protect diesel engine or petrol engine effectively; avoid because phenomenons such as the tile kilning that the machine oil shortage causes, sticking cylinders; has simple in structure, reasonable in design, practical effect; precise control, easy to use, the simultaneous faults rate is low; consumption of power not, multiple diesel engines, the machine oil decompression control of petrol engine, monitoring such as suitable various single cylinders, multi-cylinder.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that valve body, 2 is that pad, 4 was that valve rod, 5 is that oil guide slot, 6 is that handle, 7 is that the oil-feed mouth of pipe, 8 is that oil input channel, 9 is that the fuel-displaced mouth of pipe, 10 is that oil road, 11 is that the machine oil mouth of pipe, 12 is that controlling rod, 13 is a Returnning spring under last pad, 3 was.
As shown in drawings, the utility model is the pumping machine oil decompression control gear of a kind of diesel engine, petrol engine, mainly is made up of valve body 1, has inner chamber longitudinally in the valve body 1, pad 2 and following pad 3 is set in the inner chamber, and surrounds an enclosed cavity; Last pad 2 and following pad 3 are made by the rubber-like rubber cushion.The lower end of valve body 1 be provided with one can external pumping machine oil the machine oil mouth of pipe 11, the mouth of pipe of this machine oil mouth of pipe 11 is by above-mentioned 3 sealings of pad down.Be respectively equipped with an oil-feed mouth of pipe 7 and a fuel-displaced mouth of pipe 9 on the sidewall of valve body 1, the oil-feed mouth of pipe 7 outer connected tanks, the oil inlet pipe of the fuel-displaced mouth of pipe 9 external oil pumps.The above-mentioned oil-feed mouth of pipe 7 and the fuel-displaced mouth of pipe 9 communicate with above-mentioned enclosed cavity by oil input channel 8 and oil road 10 respectively.Vertically be provided with the valve rod 4 that can slide up and down in the enclosed cavity, valve rod 4 closely cooperates with the cavity of enclosed cavity; Have a circle oil guide slot 5 on the valve rod 4, this oil guide slot 5 cooperates with above-mentioned oil input channel 8 and oil road 10.The upper end of valve rod 4 withstands on pad 2 upper and lower ends and withstands on down on the pad 3.Instantly pad 3 under the promotion of engine oil pressure on very the time, drives on the valve rod 4 and move, and jack-up goes up pad 2, simultaneously oil guide slot 5 conducting oil input channels 8 and oil road 10.The upper end of above-mentioned valve rod 4 flexibly connects a controlling rod 12 longitudinally by the revolute pair structure, and Returnning spring 13 is installed on the controlling rod 12, guarantees the downforce of controlling rod 12.
Be the assurance practicability, the external handle 6 in the upper end of above-mentioned controlling rod 12, handle 6 adopts being rotatably assorted of convex to be connected with the rod end of controlling rod 12.Handle 6 can upwards spur controlling rod 12, and controlling rod 12 also can reset under the torsion of Returnning spring 13 and spur handle 6.
The extended pad 2 of going up in above-mentioned valve rod 4 upper ends links to each other with controlling rod 12.
During use, be example with the diesel engine, valve body 1 is installed in the oil pump filler opening place of diesel engine, the machine oil mouth of pipe 11 external pumping machine oil pipes on it, and the oil-feed mouth of pipe 7, the fuel-displaced mouth of pipe 9 are communicated with the oil outlet tube of fuel tank and the pump inlet pipe of diesel engine respectively.When the pumping machine oil pressure just often, following pad 3 pressurizeds upwards straighten, and jack-up valve rod 4, move on the valve rod 4 and jack-up is gone up pad 2, this moment oil guide slot 5 with oil input channel 8, oil road 10 conductings, guarantee the normal supplying fuel of diesel engine.When pumping machine oil decompression, valve rod 4 moves down under the effect of Returnning spring 13, and oil guide slot 5 is sealed oil input channel 8 and oil roads 10, thereby stops the fuel delivery of diesel engine, and the diesel engine automatic stopping is avoided the generation of machine oil decompression tile kilning or sticking cylinder phenomenon.
