Abstract
The utility model provides a hydraulic oil filter element with an oil outlet valve, which belongs to the technical field of hydraulic oil filtration devices, and comprises a filter cartridge, and a front cover and a rear cover which are arranged on both ends of the filter cartridge; an inner bearing mesh is arranged in the filter cartridge; an outer bearing mesh is arranged outside the filter cartridge; and the rear cover is provided with an oil outlet valve. In the hydraulic oil filter element with the oil outlet valve, after the oil outlet valve is added, under the normal working condition of the hydraulic filter element, the oil outlet valve is generally not opened; and in case of the sudden pressure of a machine and suddenly increased pressure difference, when the hydraulic filter element is forced to increase the flow, the oil outlet valve is opened so as to ensure the normal filtration of the hydraulic oil and the normal operation of the machine. The hydraulic oil filtration element with the oil outlet valve has the advantages of reasonable design, simple structure, reliable safety, convenient use, easy maintenance and the like.
Description
Technical field
The utility model relates to hydraulic oil filter technical field, specifically a kind of hydraulic oil filter core of taking fuel tap out of.
Background technology
General; when hydraulic machinery or hydraulic test work; usually can run into the running of full load or excess load; at this moment; the hydraulic pressure filter core will be under the unusual big situation of pressure, pressure reduction condition of work, can cause the flow of hydraulic oil not smooth, fluctuated; the hydraulic fluid pressure instability, machine works efficient does not reach its intended purposes.Hydraulic filter cored structure under prior art exists is single, can not expand parts, more and more can not satisfy the demand of modernization work.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of hydraulic oil filter core of taking fuel tap out of is provided.
The technical solution of the utility model realizes in the following manner, and the hydraulic oil filter core that this takes fuel tap out of comprises protecgulum and bonnet that filter cylinder and filter cylinder two ends are provided with, is provided with the internal support net in the filter cylinder, and filter cylinder is outside equipped with the external support net, and bonnet is provided with delivery valve.
Delivery valve is arranged on a side of the outside bonnet of filter core.
Delivery valve is arranged on a side of bonnet in the filter cylinder.
The beneficial effect that the utility model is compared with prior art produced is:
This takes the hydraulic oil filter core of fuel tap out of, interpolation setting by delivery valve, make the hydraulic pressure filter core in normal working conditions, delivery valve generally can not opened, and running under the pressure of machine burst, the situation that pressure reduction increases suddenly, when the hydraulic pressure filter core was forced to enlargement discharge, delivery valve was opened, thereby ensured the normal filtration of hydraulic oil and the normal operation of machine.This take out of the hydraulic oil filter core of fuel tap reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard etc., can be widely used in engineering machinery, heavy-duty car, hydraulic system or cleaning equipment etc.
