Description
Technical field
The utility model relates to a kind of relief valve, relates in particular to a kind of novel unidirectional relief valve.
Background technique
Relief valve is a kind of hydraulic pressure control valve.In hydraulic equipment, mainly play level pressure overflow effect and safety protection effect.In metering pump throttling regulating system, metering pump provides constant flow rate.When system pressure increases, traffic demand is reduced.This moment, relief valve was opened, and made the extra flow oil sump tank that overflows, assurance relief valve inlet pressure, and promptly pump discharge pressure is constant.During the system proper functioning, valve closing.Open overflow when having only load to surpass the limit of regulation, carry out overload protection, system pressure is no longer increased.Relief valve can also be made unloading valve usefulness, makes remote pressure regulating valve, makes the high low pressure multilevel control valve, makes sequence valve, is used to produce back pressure.Relief valve is the control unit of using in the hydraulic system in the widest and most typical hydraulic pressure oil feed line, through overflowing back fuel tank to the unnecessary flow of system, keeps the system pressure approximately constant.But the valve body of existing relief valve all is an overall structure, is inconvenient to carry out the replacing of inner body so on the one hand, and manufacture difficulty is also higher on the other hand; And pressure adjusting spring often is in stress; It is big to regulate difficulty and moment, and sealing is poor, can not guarantee the safety of pipe-line system.
Summary of the invention
According to above technical problem, the utility model provides a kind of good airproof performance, novel unidirectional relief valve rational in infrastructure, is made up of valve body (1), import (2), outlet (3), runner mouth (4), valve gap (5), screw rod (6), spool (7), adjusting strip (8), cover (9), pad (10), spring (11), nut (12), double-screw bolt (13); It is characterized in that being provided with in the valve body runner mouth, this runner mouth communicates with the import and the outlet of valve body respectively, and valve gap is fitted on the valve body; Spool is positioned at valve body, and an end of screw rod stretches in the valve body, and an end that gos deep into valve body is connected with adjusting strip; The other end is provided with valve gap, between adjusting strip and spool, is fitted with spring, in the effect lower valve core and the sealing of runner mouth metallicity of this spring; Be processed with outside thread on the said screw rod; On screw rod, be set with the nut that matches with outside thread, be fitted with cover on the valve gap, cover is fixed on the valve gap through double-screw bolt; Be equipped with pad between valve gap and the valve body, valve body is connected through four double-screw bolts with valve gap.
The beneficial effect of the utility model is: whole structure of relief valve is reasonable, can carry out pressure easily through screw rod and regulate, and guarantees the stability of relief valve work, and between valve body and valve gap, is equipped with pad, has strengthened sealability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
According to shown in Figure 1, be provided with runner mouth (4) in the valve body (1), this runner mouth (4) communicates with the import (2) and the outlet (3) of valve body (1) respectively; Valve gap (5) is fitted on the valve body (1), and spool (7) is positioned at valve body (1), and an end of screw rod (6) stretches in the valve body (1); An end that gos deep into valve body is connected with adjusting strip (8), and the other end is provided with valve gap (5), between adjusting strip (8) and spool (7), is fitted with spring (11); Spool when proper functioning (7) relies on the pressure roof pressure of spring (11) on runner mouth (4); Because therefore the effect spool (7) of spring (11) and the sealing of runner mouth metallicity make whole relief valve be in closed condition, when oil when the import (2) on the right flows into valve body (1) inside and oil pressure and increases above spring (11) pressure; Spool (7) is just backed down; Oil just flows out from the left side outlet (3) of valve body (1), and flows back to fuel tank through honeycomb duct, to guarantee the safety of pipeline.Screw rod is processed with outside thread on (6), on screw rod (6), is set with the nut (12) that matches with outside thread, and the pressure of spring (11) can lean on screw rod (6) to regulate, and is loosening in order to prevent screw rod (6), also tight with nut (12) on the top of screw rod (6).Be fitted with cover (9) on the valve gap (5), cover (9) is fixed on the valve gap (5) through double-screw bolt (13), and valve gap (5) is gone up equipped cover (9) can effectively protect screw rod (6), thereby guarantees the stability of relief valve work.Also be equipped with pad (10) between valve gap (5) and the valve body (1), described valve body (1) is connected through four double-screw bolts (13) with valve gap (5), and pad (10) can prevent that oil from spilling in valve body (1).Whole structure of relief valve is reasonable, can carry out pressure very easily through screw rod (6) and regulate, and guarantees the stability of relief valve work, and between valve body (1) and valve gap (5), is equipped with pad, has strengthened sealability.
