Abstract
The utility model relates to an oil pressure automatic adjusting controller. On the basis of the manual regulation valve, the existing structures of the automatic valve seat and the valve core threaded rod are modified, the oil pressure automatic adjusting controller is additionally provided with a spring, a sliding sleeve and a valve sleeve, and particularly an automatic actuating mechanism is designed. Especially, the oil pressure automatic adjusting controller has simple structure, realizes the oil pressure control automation, particularly passes through the disposable oil pressure adjustment, causes the oil pressure of the system to be stable for a long term, and thus provides the convenient condition for the stable combustion of the fuel. Simultaneously, as part of fuel passes through the oil pump in a reciprocating way in overflow, the utility model plays the function of the mechanical stirring, causes the dead oil with water to obtain the primary emulsification, is favorable to combust, and particularly creates the convenient condition for realizing the emulsifying treatment of the dead oil adding water.
Description
The utility model relates to the automatic control set for adjusting of a kind of oil pressure, especially can the controlled system with self-regulation oil pressure, and the stable system working pressure can realize the automation of fuel feeding center oil pressure-controlled especially.
At present, known hydraulic pressure control device, be to utilize manual modulation valve to be installed on the connecting tube of oil feed pump and oil return, it mainly is to limit system's MTP by the overflow effect, because it is only limited to manual tune, does not possess automatic regulatory function, so, when system changed with oil mass, system oil pressure was along with fluctuation, the system works pressure transient.
The purpose of this utility model provides a kind of oil pressure automatic controller, and it not only can especially possess oil pressure and regulate the control function automatically in order to regulate qualification system MTP, therefore, sets up the system oil pressure long-term stability by primary oil pressure.
The purpose of this utility model is achieved in that it by the manual tune valve chest, has increased valve pocket, keeps seal arrangement, has revised the spool of screw rod, and ad hoc sliding sleeve and spring have constituted the automatic control set for adjusting of oil pressure.Before the use, first rotary screw makes it force the sliding sleeve displacement, and meanwhile, the sliding sleeve of displacement forces the spring stress compression again, and spring stress is directly passed to spool again, and spool tightly is pressed on the lining valve.When oil pump starts,, be positive differential pressure here owing to oil pump outlet oil pressure pressure reduction occurs greater than specified operating oil pressure.The appearance of this positive differential pressure forces spool stressed, and spring generation reaction force is made the spring retraction, and spool is forced to open the generation overflow, what of this spillway discharge, fully relevant with the malleation extent, this overflow, exactly can cause the variation of oil pressure, make the system works oil pressure stable.When the system works oil mass changed, instantaneous system oil pressure respective change and pressure reduction occurs was Negative Pressure Difference here, the appearance of this Negative Pressure Difference, transfer reaction diminishes these two kinds of pressure differences before pump rapidly, because the variation of this difference, stressed corresponding the diminishing of spool, the reaction force of spring also phase strain is reduced, so spool descends, spillway discharge reduces, in actual use, the variation of oil pressure and spillway discharge is varied to proportional relation.Therefore, regulated spillway discharge before the pump, also with regard to control corresponding the system works oil pressure because this transformation period is very short, people are often imperceptible, can not impact the use of producing, so it is continual and steady to be considered as oil pressure.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a longitudinal sectional drawing of the present utility model.
Existing manual modulation valve is made up of housing, actuator and seal arrangement.At this existing structure of having revised valve seat, spool screw rod, spring, sliding sleeve, valve pocket have been appended, ad hoc automatic executing agency.
Show entire infrastructure among Fig. 1: valve bush (1), spool (2), valve seat (3), pressure pad (4), stage clip (5), sliding sleeve (6), valve pocket (7), pressure pad (8), valve gap (9), packing ring (10), filler (11), gland (12), block (13) and screw rod (14) in order to the oil pressure automatic controller that replaces manual modulation valve.
In Fig. 1 embodiment, in frame set, set up valve pocket (7).In actuator, the screw rod spool is resolved into spool (2) and screw rod (14), the centre is provided with the sliding sleeve (6) that transition connects, sliding sleeve (6) and the middle stage clip (5) that is provided with of spool (2).Wherein, valve pocket is established skidway hole in (7), and the two ends internal and external threads of valve pocket (7) connects.Spool (2) upper boom inserts in the sliding sleeve (6) and is slidingly matched, sliding sleeve (6) is provided with the hole of radially breathing, sliding sleeve (6) and the middle stage clip (5) that is with of spool (2), sliding sleeve (6) is slidingly matched the upper end of sliding sleeve (6) and screw rod (14) sliding contact with valve pocket (2).
The utility model comes into operation at present, and effect is obvious.
Claims (3)
1, a kind of in order to replace the oil pressure automatic controller of manual modulation valve, form by housing, actuator and seal arrangement, it is characterized in that: in frame set, have additional valve pocket (7), the screw rod spool resolves into spool (2) and screw rod (14) in actuator, the centre is provided with the sliding sleeve (6) that transition connects, sliding sleeve (6) and the middle stage clip (5) that is provided with of spool (2).
2, according to the oil pressure automatic controller shown in the claim 1, it is characterized in that: valve pocket is provided with skidway hole in (7), and the two ends internal and external threads of valve pocket (7) connects.
3, according to oil pressure automatic controller that claim 1 increased, it is characterized in that: spool (2) upper boom inserts in the sliding sleeve (6), be slidingly matched, sliding sleeve is provided with the hole of radially breathing in (6), sliding sleeve (6) and the middle stage clip (5) that is with of spool (2), sliding sleeve (6) is slidingly matched the upper end of sliding sleeve (6) and screw rod (14) sliding contact with valve pocket (7).
