Abstract
The utility model discloses a self filtering type pipe connection bolt for a diesel oil supply system, which is used for the connection between an oil pipe and oil pump elements in an oil supply circuit. The self filtering type pipe connection bolt comprises a bolt body, wherein an axial oil hole and a radial oil hole which are vertically communicated with each other are formed on the bolt body, and a steel wire filter screen is arranged at the oil inlet of the axial oil hole. The utility model has the steel wire filter screen added in the oil hole of an ordinary pipe connection bolt, thereby being capable of multi-level filtration to fuel oil and improving the filter effect of the fuel oil; moreover, the structure is simple, and repeated use is realized.
Description
Technical field
The utility model relates to a kind of self-filtering type pipe connecting bolt that is used for the fuel system for diesel engine oil circuit.
Background technique
Fuel system for diesel engine is had relatively high expectations to fuel oil, although fuel tank oil outlet, oil pump oil outlet etc. locate generally all to be provided with filtrating equipment, but from whole system, how to accomplish the fuel oil filtering effect better, prevent that impurity from entering the oil pump components and parts, the working life and the performance that concern whole system, in the oil circuit of whole system, it is more to be used for the pipe connecting bolt quantity that is connected between oil pipe and the components and parts, and these pipe connecting bolts only play the filtering function of the unmatchful hydraulic oil of path effect of hydraulic oil.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of self-filtering type pipe connecting bolt that improves oil supply system intermediate fuel oil filtering effect is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of self-filtering type pipe connecting bolt, be used for being connected between fuel path oil pipe and the oil pump element, comprise bolt body, offer on the bolt body axial oilhole with the radial direction oil hole of the vertical perforation of axial oilhole, the filler opening place of described axial oilhole is provided with Steel net.
Further, described Steel net is pressed in the axial oilhole by pressure ring.
The beneficial effects of the utility model are: the utility model is provided with Steel net in the oil through of common tube connecting bolt, can carry out multi-level filtration to fuel oil, and is simple and practical to improve the filtering effect of fuel oil, and can reuse.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. bolt bodies, 2. axial oilhole 3. radial direction oil hole 4. Steel nets 5. pressure rings among the figure
Embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of self-filtering type pipe connecting bolt as shown in Figure 1, be used for being connected between fuel path oil pipe and the oil pump element, comprise bolt body 1, offer on the bolt body 1 axial oilhole 2 with the radial direction oil hole 3 of axial oilhole 2 vertical perforations, the filler opening place of described axial oilhole 2 is provided with Steel net 4, and described Steel net 4 is pressed in the axial oilhole 2 by pressure ring 5.Because pipe connecting bolt usage quantity is more in the whole hydraulic system, after in each pipe connecting bolt, Steel net 4 being set all, can carry out multi-level filtration to the fuel oil that passes through, prevent that effectively impurity from entering the oil pump components and parts, improve the working life and the usability of whole system, simultaneously, pipe connecting bolt described in the utility model can be reused, when using built-in Steel net 4 of a specified duration and is stopped up by impurity, only need wash away in the other direction and can reuse with fuel oil.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
Claims (2)
1. self-filtering type pipe connecting bolt, be used for being connected between fuel path oil pipe and the oil pump element, comprise bolt body (1), offer on the bolt body (1) axial oilhole (2) with the radial direction oil hole (3) of the vertical perforation of axial oilhole (2), it is characterized in that: the filler opening place of described axial oilhole (2) is provided with Steel net (4).
