Description
One, affiliated field:
The invention belongs to relief valve design and manufacturing technology field, particularly a kind of modular type circular visual overflow combined valve that is widely used in the hydraulic system.
Two, background technique:
Relief valve is a kind of one of significant components that is widely used in the hydraulic system, influences system works owing to relief valve often produces undesired leakage.For example, in hydraulic pressure clamping and clamping system, after the execution oil cylinder was finished clamping, the demand of high pressure oil had not needed substantially, as long as keep the amount of leakage of each parts, keep certain pressure to get final product, and the increase of the energy consumption that the pumping plant running brings, because long-term operation brings the temperature variation of oil, the instability of pressure, cause the wearing and tearing and the leakage of hydraulic unit, the shortening of component life etc.Whether the leakage of relief valve is the key of system's operation, and this wherein just relates to the adjusting and the inspection of relief valve, therefore, presses for a kind of safe and reliablely at present, checks and unidirectional modular type circular visual overflow combined valve easy to adjust.
Three, summary of the invention:
The objective of the invention is, to the situation of pin prior art, it is long, safe and reliable to manufacture and design a kind of life-span, checks and circular visual overflow combined valve easy to adjust.
The present invention realizes by following manner: a kind of visual overflow combined valve, comprise valve body 1, spool part and the visual controlling mechanism of spool thereof that valve body 1 upper end is provided with, the one-way valve 16 that valve body 1 lower end is provided with, the oil inlet hole 12 that is provided with on the valve body 1 of spool part lower end, and the relief valve oil drainage hole 11 that is provided with on the valve body 1 of spool part periphery, it is characterized in that: circular valve 1 is adopted in valve body 1 design, the center of valve body 1 is provided with spool 3 and the oil inlet hole 12 of one-way valve 16 on same vertical center line with the spool part, the valve body 1 of spool part periphery is provided with relief valve oil drainage hole 11, as shown in Figure 1.
Said spool part is made up of valve base sealing pad 13, valve seat 2, spool 3 that oil extraction solenoid coil 6 and lower end thereof set gradually, visual transparent glass tube 8 neutral positions corresponding to the visual controlling mechanism of spool on the oil extraction solenoid coil 6 are provided with relief valve oil extraction circular hole 15, as shown in Figure 1.
The visual controlling mechanism of said spool is made up of the visual transparent glass tube 8, the glass tube sealing gasket 14 of visual transparent glass tube 8 upper ends and the glass tube sealing gasket 14 of glass jam nut 9 and visual transparent glass tube 8 lower ends that are arranged on the guide rod 4, pressure adjusting spring 5, voltage regulation screw 7 and the protective cap 10 thereof that withstand in the oil extraction solenoid coil 6 on the spool 3, be provided with in oil extraction solenoid coil 6 peripheries; wherein; relief valve oil drainage hole 11 upper end-hole that are provided with on the valve body 1 are just in time facing between visual transparent glass tube 8 and the oil extraction solenoid coil 6, as shown in Figure 1.
Present technique is a kind of unidirectional modular type circular visual overflow combined valve, its working procedure and principle are: when the high pressure oil high pressure enters valve seat 2 by oil inlet hole 12, jack-up spool 3 promotes guide rod 4 and compresses pressure adjusting spring 5, this moment, high pressure oil passed through the relief valve draining to the oil extraction solenoid coil 6 of valve seat, by two small sircle holes in the oil extraction solenoid coil 6, be that relief valve oil extraction circular hole 15 is discharged, fall into to transparent tube be visual transparent glass tube 8, and enter in (perhaps getting back to) two aperture relief valves oil drainage hole 11 and enter fuel tank.Screw in when carrying out voltage regulation screw 7 to be screwed out when pressure is regulated, as shown in Figure 1.Owing to the spool part of present technique and the reasonable in design of the visual controlling mechanism of spool thereof, long service life, safe and reliable, adopt visual transparent glass tube 8 in the visual controlling mechanism of spool simultaneously, therefore, inspection and adjusting are convenient at the right time.
