Abstract
The invention provides a hydraulic automatic reversing valve, relating to a reversing valve widely applicable to double-line grease centralized-lubricating systems in metallurgy, chemical industry, electric power, cement machinery, building material machinery and port machinery. The hydraulic automatic reversing valve comprises a pressure-regulating hand wheel (1), a pressure-regulating oil cylinder (2), a fastening nut (3), a cover shell (4), a pressure gauge (5), an oil supply port (6), a valve body (7), a reversing frequency generator (8), an oil inlet (9) and an oil return port (10) and has the advantages of compact structure, small volume, light weight, convenience for operation, stability of reversion, small pressure fluctuating value, high used pressure grade, reliable performance, adjustable reversing pressure and the like; and by using the hydraulic automatic reversing valve, the system faults are reduced, and the investment cost is lowered.
Description
Technical field:
The present invention relates to a kind of selector valve that is widely used in metallurgy, chemical industry, electric power, cement machinery, building material machinery, the harbour machinery two-wire grease concentrating lubricating system, be specifically related to a kind of hydraulic pressure automatic diverter valve.
Background technique:
Selector valve is the position control valve with two or more liquid forms and two above hydraulic fluid ports.Be communication, cut-out and the commutation that realizes hydraulic oil flow, and the valve of discharge degree and sequentially-operating control.Can be divided into hand-operated direction valve, solenoid directional control valve, electro-hydraulic reversing valve etc.It claims Chris's valve again, has multidirectional adjustable passage, can change direction of flow in good time.By the outer drive transmission device rotating driveshaft of valve, drive and shake connecting lever during work, start valve plate, when making working fluid and lead to the lower exit of valve from left entry, the time and lower exit is led in the conversion of people's right entry, realized the purpose that periodic transformation flows to.This transfer valve has a wide range of applications in oil, Chemical Manufacture, and is the most commonly used in the ammonia system.In addition, selector valve also can make the structure of flap formula, is used for the occasion than small flow more.Only need rotate handwheel comes the conversion working fluid by flap the flow direction during work.The advantage of valve plate formula is that action is accurate, automaticity is high, working stability is reliable, drives and cooling system but need set up, and structure is comparatively complicated; Flap formula structure is then simpler, is used on the less production technology of flow more.
Present selector valve is of a great variety, but its restricted application, and complex structure is not compact, and volume is big, and the pressure surge value is big, commutation pressure is non-adjustable.
Summary of the invention:
The purpose of this invention is to provide a kind of hydraulic pressure automatic diverter valve, advantages such as it has compact structure, volume is little, in light weight, easy to operate, commutation is stable, the pressure surge value is little, working pressure grade height, reliable performance, commutation adjustable in pressure have reduced the system failure, have reduced cost of investment.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it is by pressure regulation handwheel 1, pressure regulation oil cylinder 2, tightening nut 3, case 4, pressure gauge 5, oil-feed port 6, valve body 7, commutating frequency generator 8, filler opening 9 and return opening 10 are formed, pressure regulation handwheel 1 is arranged on the upper end of pressure regulation oil cylinder 2, pressure regulation oil cylinder 2 is connected with case 4 by tightening nut 3, case 4 is arranged on the upper end of valve body 7, the both sides of case 4 are provided with pressure gauge 5, the front end both sides of valve body 7 are respectively arranged with oil-feed port 6, the rear end of valve body 7 is provided with filler opening 9 and return opening 10, and commutating frequency generator 8 is connected with valve body 7.
Commutation pressure is regulated by pressure regulation handwheel 1, and pressure raises clockwise, otherwise pressure reduces.Filler opening 9 with pump hydraulic fluid port and be connected, return opening 10 connects gasoline tank, the oil-feed port 6 of valve body 7 both sides is connected with two oil feed lines respectively.Work as left side road binders pressure during work and reach setting pressure, selector valve automatically switches to the right side road, and lubricant pump just can be circularly to two pipeline feed lubricating grease like this.
Advantages such as the present invention has compact structure, volume is little, in light weight, easy to operate, commutation is stable, the pressure surge value is little, working pressure grade height, reliable performance, commutation adjustable in pressure have reduced the system failure, have reduced cost of investment.

Fig. 1 is a structural representation of the present invention, and Fig. 2 is the rear view of Fig. 1.
Embodiment:
With reference to Fig. 1-2, this embodiment is by the following technical solutions: it is by pressure regulation handwheel 1, pressure regulation oil cylinder 2, tightening nut 3, case 4, pressure gauge 5, oil-feed port 6, valve body 7, commutating frequency generator 8, filler opening 9 and return opening 10 are formed, pressure regulation handwheel 1 is arranged on the upper end of pressure regulation oil cylinder 2, pressure regulation oil cylinder 2 is connected with case 4 by tightening nut 3, case 4 is arranged on the upper end of valve body 7, the both sides of case 4 are provided with pressure gauge 5, the front end both sides of valve body 7 are respectively arranged with oil-feed port 6, the rear end of valve body 7 is provided with filler opening 9 and return opening 10, and commutating frequency generator 8 is connected with valve body 7.
Commutation pressure is regulated by pressure regulation handwheel 1, and pressure raises clockwise, otherwise pressure reduces.Filler opening 9 with pump hydraulic fluid port and be connected, return opening 10 connects gasoline tank, the oil-feed port 6 of valve body 7 both sides is connected with two oil feed lines respectively.Work as left side road binders pressure during work and reach setting pressure, selector valve automatically switches to the right side road, and lubricant pump just can be circularly to two pipeline feed lubricating grease like this.
Advantages such as this embodiment has compact structure, volume is little, in light weight, easy to operate, commutation is stable, the pressure surge value is little, working pressure grade height, reliable performance, commutation adjustable in pressure have reduced the system failure, have reduced cost of investment.
