Abstract
The utility model provides a pressure stabilizing filter for hydraulic oil. The pressure stabilizing filter comprises a body in which a cavity is formed, wherein a cylindrical filter screen is placed in the cavity; a hydraulic oil inlet and a hydraulic oil outlet are respectively formed in the body at the inner side and the outer side of the filter screen; a valve core is arranged at the hydraulic oil inlet and is in transmission connection with an adjusting lever; an adjusting handle is arranged at the upper end of the adjusting lever; a cleaning port in communication with the inner part of the filter screen is formed in the bottom part of the body; a piston cylinder communicated with the hydraulic oil inlet is arranged at the upper part of the body; the adjusting lever is arranged in a piston rod; a piston is arranged in the middle part of the adjusting lever; a spring is arranged through the adjusting rod; the lower end of the spring relates to the piston in a crimping way, while the upper end of the spring also relates to the lower end of the adjusting handle in the crimping way; an oil-resistant elastic rubber body is arranged between each of the two ends of the filter screen and the body; and the lower end of the cleaning port is connected with a water supply pipeline by a ball valve. The pressure stabilizing filter for the hydraulic oil is convenient to wash and maintain, the water pressure is stable, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to a kind of hydraulic oil pressure-stabilization filter.
Background technology
At present, in diamond graphite production process, due to the hydraulic oil Reusability, hydraulic oil is polluted, well cuts content is higher, contains the solid impurities such as pyrophillite impurity, simultaneously, and the impact to system's valve member that can cause during ftercompction.
The utility model content
The utility model provides a kind of hydraulic oil pressure-stabilization filter, plays the effect of impurity screening and voltage stabilizing.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of hydraulic oil pressure-stabilization filter, comprise body, be provided with cavity in body, be provided with the tubular filter screen in cavity, be respectively equipped with the entrance and exit of hydraulic oil inside and outside filter screen on the body of both sides, be provided with spool in the porch, spool and adjusting rod are in transmission connection, and the upper end of adjusting rod is provided with regulating handle, body bottom be provided with filter screen in the cleaning mouth that is communicated with.
Body top is provided with the piston cylinder that is communicated with entrance, and adjusting rod is arranged in piston rod, is provided with piston in the middle part of adjusting rod, and spring is located on adjusting rod, spring lower end and piston crimping, spring upper end and regulating handle lower end crimping.
Be provided with the oil resistant elastic rubbery body between filter screen two ends and body.
A cleaning mouthful lower end is connected with water supply line by ball valve.
The utility model specifically has the following advantages:
1: conveniently flushing is safeguarded, only need open cleaning mouthful ball valve with regard to flushable filter screen, and brute force flings the negative pressure of pressure oil and screen surface formation can effectively discharge impurity particle, repeatedly rinses filter screen is more cleaned;
2, oil line protector is arranged on the oil-feed house steward, effectively removes the impurity such as silt, suspension in oil, protects other valve member equipment, increases the service life;
3, stablize hydraulic pressure, reduce water hammer, prevent that pressure is uneven, protection refiner equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of hydraulic oil pressure-stabilization filter, comprise body 6, be provided with cavity in body 6, be provided with tubular filter screen 5 in cavity, be respectively equipped with entrance 7 and the outlet 8 of hydraulic oil inside and outside filter screen 5 on the body 1 of both sides, 7 places are provided with spool 4 at entrance, spool 4 is in transmission connection with adjusting rod 3, and the upper end of adjusting rod 3 is provided with regulating handle 1, body 6 bottoms be provided with filter screen in the cleaning mouth 9 that is communicated with.Body 6 tops are provided with the piston cylinder that is communicated with entrance 7, and adjusting rod 3 is arranged in piston rod, and adjusting rod 3 middle parts are provided with piston, and spring 2 is located on adjusting rod, spring 2 lower ends and piston crimping, spring 2 upper ends and regulating handle 1 lower end crimping.Be provided with oil resistant elastic rubbery body 10 between filter screen 5 two ends and body 6.Cleaning mouthful 9 lower ends are connected with water supply line by ball valve.
Filtering function: have the oil of impurity to enter filter from entrance 7, flow out pure oil from exporting 8 after filter screen 5 filters, filter screen 5 has adopted the filter screen of stainless steel, plays a role in filtering, there is oil resistant elastic rubbery body 10 at filter screen 5 two ends, can play to prevent that oil from entering in filter screen from the end.Cleaning mouth 9 is for regular maintenance designs, and the certain life cycle of every mistake is opened the ball valve that Butterworth Hatch 9 connects below, close outlet 8, make to be attached to dirty on filter screen 5 and to flow out from Butterworth Hatch 9 under the impact of hydraulic oil, play the effect of cleaning filter screen 5, avoided frequent dismounting valve body.
Voltage stabilizing function: by regulating handle 1, pressure is adjusted to certain force value, higher than setting pressure, imported hydraulic oil promotes adjusting rod 3 Compress Springs 2 and moves up when the pressure of imported hydraulic oil, thereby reduces the open degree of spool 4, reduces outlet pressure.
The utility model can reduce too high hydraulic pressure, regulates the moment water pressure fluctuations, avoids the waterpipe jointing that water hammer causes to leak, and can accurately read out saliva from the top reading dial and press, and the adjustable joint of water outlet pressure points to desirable value by rotary dial and gets final product.
After using the utility model, reduced the repair and replacement frequency of oil circuit components and parts, larger economic benefit is arranged, the utility model also can use in the pipeline that supplies water.
