Summary of the invention
The purpose of this utility model is to provide a kind of engine oil pressure alarm that is not easy to occur oil leakage phenomenon.
The utility model adopts following technological scheme: a kind of engine oil pressure alarm, comprise and be provided with the fitting seat of oil passageway and be arranged on the end cap on fitting seat with inner chamber, between end cap and fitting seat, be provided with the diaphragm for oil passageway and end cap inner chamber are separated, diaphragm top is provided with stationary contact circle and movable contact circle successively, in the inner chamber of end cap, be provided with the spring that is positioned at movable contact circle top and the top press fit of movable contact circle, between stationary contact circle and diaphragm, be provided with the push rod that promotes the action of movable contact circle, between described fitting seat and end cap, be provided with lining, two walls of lining contact respectively cooperation with end cap with fitting seat.
The lower end of described end cap is embedded into the upper end of described fitting seat, and the lower end of described lining has the O-ring seal for being sealed and matched with fitting seat.
Described lining is made by stainless steel material.
The top of described spring is provided with the adjusting screw rod with this spring top press fit, and this adjusting screw rod spiral is arranged on described end cap.
Between described adjusting screw rod and spring, be provided with the gland that metallic material is made, this gland has outer the turning edge coordinating with described spring block.
The utility model arranges lining between fitting seat and end cap; two walls of lining coordinate with fitting seat and end cap respectively; even after the long-term use of end cap; even if there is damaged distortion in the lower part of end cap; owing to there being the protection of lining; sealing can not change, and therefore machine oil can not leak from fitting seat and seal ring.Engine oil pressure alarm of the present utility model is simple in structure, cost is low, and long term high temperature work is not leakage of oil easily also.
Further, the protective action of lining, further prevents that machine oil from leaking from the junction of fitting seat and seal ring.
Further, the lining that stainless steel is made has high temperature resistant, corrosion resistant feature, is not easy to occur deformation.
Further, can regulate by screwing adjusting screw rod the pressure of Regulation spring, thereby change the alarm pressure value of alarm.
Further, the gland arranging between adjusting screw rod and spring can make the operation that screws adjusting screw rod be more prone to.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
A kind of specific embodiment of the utility model as shown in Figure 1, engine oil pressure alarm of the present utility model comprises having the fitting seat 1 of oil passageway 12 and be arranged on the end cap 9 on fitting seat with inner chamber, the upper end of end cap 9 outsides has the electrical equipment connection inserted sheet that is communicated with alarm circuit, fitting seat 1 upper end offers up big and down small shoulder hole, the lower end of end cap is embedded in the macropore section of upper end shoulder hole of described fitting seat, between the macropore section of the shoulder hole of fitting seat 1 and end cap, be provided with successively from bottom to up seal ring 2, diaphragm 3 and stationary contact circle 5, diaphragm 3 is made by elastic material, structure raises up centered by stationary contact circle 5, between diaphragm and stationary contact circle, be provided with push rod 4, the upper end of this push rod passes from stationary contact Quan center, lower end coordinates with stationary contact circle block, the upper end of push rod 4 is provided with movable contact circle 6, in the inner chamber of end cap 9, be provided with the spring 7 that is positioned at movable contact circle top and the top press fit of movable contact circle, the top of movable contact circle is provided with the spring 7 with the top press fit of movable contact circle, the top of spring 7 is provided with the adjusting screw rod 10 with this spring top press fit, this adjusting screw rod spiral is arranged on described end cap 9, between adjusting screw rod 10 and spring 7, be provided with the gland 11 that metallic material is made, this gland 11 has outer the turning edge coordinating with described spring block, during use, can regulate by screwing adjusting screw rod 10 pressure of Regulation spring, thereby change the alarm pressure value of alarm.Between end cap 9 and fitting seat 1, be provided with the lining 8 that stainless steel material is made, the inside and outside wall of lining 8 contacts cooperation with end cap 9 with fitting seat 1 respectively, the lower end of lining has the seal ring for coordinating with end cap sealing bottom surface, and O-ring seal 2 is between fitting seat 1 and stationary contact circle 5.
