Abstract
The utility model relates to a pressure regulating valve which comprises a valve body 1, a ball 2, a spring guide sleeve 7, a spring 5 and a blind nut 6. The valve body 1 is tubular, one side of the valve body 1 is provided with inner threads, the spring guide sleeve 7 is installed on one side, a step is arranged on the other side, the large-diameter portion of the step is close to the inner threads, a hole is formed in the position close to the small-diameter portion, a tightening structure 8 is arranged on the outer side of the bottom of the spring guide sleeve 7, the ball 2 is clamped on the step, the spring 5 is respectively clamped between the ball 2 and the spring guide sleeve 7, an anti-loosening nut 4 and the blind nut 6 are sequentially installed on the threads of the spring guide sleeve 7 exposing out of the valve body 1, and the bottom of the blind nut 6 is closed. The pressure regulating valve is simple in structure, reliable in performance, can achieve accurate control through calculation, control lubricating oil pressure in a system and ensure the stability of the lubricating oil pressure in the system after working for a long period of time or when the outside environment changes.
Description
Technical field
The utility model relates to a kind of pressure regulator valve, especially a kind of pressure regulator valve that can guarantee to guarantee pressure stability in pressure surge situation.
Background technique
Pressure regulator valve is the conventional regulator of machinery lubrication system, and its working principle is by spring force, to control pressure regulator valve to carry out cracking pressure.Along with the increase of pressure regulator valve operating time, the Young's modulus of spring reduces, the bearing capacity of spring declines, and causes the outlet pressure fluctuation of lubricating oil pump larger, can not guarantee the lubricating ability requirement of retarder.Simultaneously, variation due to external environment, while carrying out aerial mission as helicopter in plateau section, the lubricating oil pressure of lubricating oil pump declines more obvious, pressure regulator valve carries out work under the pressure condition of original start, cannot guarantee usage requirement, therefore need a kind of can control system in lubricating oil pressure, guarantee the pressure regulator valve of pressure stability.
Summary of the invention
The purpose of this utility model be to provide a kind of can control system in lubricating oil pressure, guarantee the pressure regulator valve of pressure stability, can after longevity of service or when extraneous environmental change, guarantee the stable of lubricating oil pressure in system.
The technical solution of the utility model is, pressure regulator valve comprises valve body, ball, spring guide, spring, blind nut, described valve body is tubulose, one side is provided with internal thread and spring guide is installed, opposite side is provided with step, described step major diameter part is near internal thread, and arrange porose in the position near minor diameter, described spring guide bottom outside is provided with screwing structure, described ball is stuck on step, spring withstands on respectively between ball and spring guide, spring guide is exposed on the screw thread of valve body outside lock nut and blind nut is installed successively, described blind nut bottom lock.On described valve body, be also provided with mounting structure, screwing structure straight groove or the cross recess of spring guide bottom outside, be provided with packing ring between lock nut and valve body and between lock nut and blind nut.
The utility model is provided with spring guide, by screwing structure, moves axially, and the decrement of adjusting spring is controlled the cracking pressure of ball, and lock nut guarantees the modulating valve reliable operation after adjustment, and blind nut has the effect of sealing and dustproof.The utility model is simple in structure, and reliable performance can realize accurate control by calculating, can control system in lubricating oil pressure, can after longevity of service or when extraneous environmental change, guarantee the stable of lubricating oil pressure in system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, pressure regulator valve comprises valve body 1, ball 2, spring guide 7, spring 5, blind nut 6, described valve body 1 is tubulose, one side is provided with internal thread and spring guide 7 is installed, opposite side is provided with step, described step major diameter part is near internal thread, and arrange porose in the position near minor diameter, described spring guide 7 bottom outside are provided with screwing structure 8, described ball 2 is stuck on step, spring 5 withstands on respectively between ball 2 and spring guide 7, spring guide 7 is exposed on the screw thread of valve body 1 outside lock nut 4 and blind nut 6 is installed successively, described blind nut 6 bottom locks.On described valve body 1, be also provided with mounting structure 9, the screwing structure 8 of spring guide 7 bottom outside is straight groove or cross recess, between lock nut 4 and valve body 1 and between lock nut 4 and blind nut 6, is provided with packing ring 3.
