Abstract
The utility model discloses a locking structure suitable for full-hydraulic steering gear valve piece overload valve contains a casing, the casing in be equipped with one and mend oil valve assembly and an overload valve spring, one side of mend oil valve assembly be equipped with an overload valve disk seat, overload valve spring extrusion mend oil valve assembly with overload valve disk seat, one side of overload valve disk seat be equipped with a lock nut. The locking nut is tightly attached to the end face of the overload valve seat. Because the lock nut is tightly attached to the end face of the overload valve seat, the space of the lock nut is extremely limited, and the pressure of the overload valve is reduced extremely even if the lock nut is displaced, so that the use is not influenced.
Description
Technical Field
The utility model relates to an all-hydraulic steering gear, more exactly, be a locking structure who is applicable to all-hydraulic steering gear valve block overload valve.
Background
When the full hydraulic steering gear with the valve block runs on an agricultural vehicle, sudden change type impact of different degrees can be generated on the oil cylinder sometimes due to the complex running road condition of the agricultural vehicle, and the impact on the oil cylinder is transmitted to an overload valve on the steering gear valve block through hydraulic oil, so that the displacement of a valve seat of the overload valve can be caused, and the pressure of the overload valve is reduced. If the overload valve pressure drops too low, it will cause the vehicle to be unable to turn around when entering the hollow, and if the overload valve pressure drops below the safety valve pressure, it will cause the problem that the safety valve is not open and the overload valve is open, and the vehicle may also turn heavy when traveling on a flat road.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that prior art exists to a locking structure who is applicable to full hydraulic steering ware valve block overload valve is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the anti-loose structure suitable for the overload valve of the valve block of the full-hydraulic steering gear is characterized by comprising a shell, wherein an oil supplementing valve assembly and an overload valve spring are arranged in the shell, one side of the oil supplementing valve assembly is provided with an overload valve seat, the overload valve spring extrudes the oil supplementing valve assembly and the overload valve seat, and one side of the overload valve seat is provided with a locking nut.
As the preferred embodiment of the utility model, lock nut hug closely the terminal surface of overload valve disk seat.
The utility model discloses a locking structure suitable for full hydraulic steering ware valve block overload valve has following advantage: because the lock nut is tightly attached to the end face of the overload valve seat, the space of the lock nut is extremely limited, and the pressure of the overload valve is reduced extremely even if the lock nut is displaced, so that the use is not influenced.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is the utility model discloses a locking structure's schematic structure suitable for all-hydraulic steering gear valve block overload valve.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1, the anti-loose structure suitable for the overload valve of the valve block of the full hydraulic steering gear comprises a housing 6, an oil supplementing valve assembly 3 and an overload valve spring 4 are arranged in the housing 6, an overload valve seat 1 is arranged on one side of the oil supplementing valve assembly 3, the overload valve spring 4 extrudes the oil supplementing valve assembly 3 and the overload valve seat 1, and a locking nut 2 is arranged on one side of the overload valve seat 1.
The locking nut 2 is tightly attached to the end face of the overload valve seat 1.
When in use, the locking nut 2 is tightly attached to the end face of the overload valve seat 1, the space of the locking nut 2 is extremely limited, and the overload valve pressure is reduced extremely even if the locking nut is displaced, so that the use is not influenced.
The anti-loosening structure applicable to the overload valve of the full-hydraulic steering gear valve block is simple in structure, obvious in effect, low in cost and high in practicability.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
