Abstract
The utility model relates to the field of hydraulic solenoid valves, and discloses a hydraulic solenoid valve sleeve, wherein the end part of the valve sleeve for fixing a limiting spring seat is the front end of the valve sleeve, and the front end of the valve sleeve is gathered in a bag pleat shape; after the front end of the valve sleeve is gathered, the outer side wall of the front end of the valve sleeve is provided with a plurality of concave parts which are distributed around the axis of the valve sleeve; the concave part is correspondingly provided with a convex part on the inner side wall of the front end of the valve sleeve. In this way, the utility model discloses can make the spring holder remain throughout at home position under the condition that bears great pressure oscillation and impact force, can not take place the displacement, by ejecting and impaired phenomenon.
Description
Technical Field
The utility model relates to a hydraulic pressure solenoid valve field especially relates to a hydraulic pressure solenoid valve barrel.
Background
At present, a spring seat in a hydraulic electromagnetic valve is pressed into a valve sleeve through interference fit, or the front end of the valve sleeve is cut, and the cut part is inwards rolled to form a flanging barb to fix the spring seat. Although the two schemes are simple and convenient to operate, the pressure oscillation or impact which can be borne by the spring seats fixed by the two schemes is limited, and high-pressure oscillation and pressure impact exist in the system in a real application environment, so that the interference fit or the flanging barb is easy to fail, the spring seats are displaced, or are broken and damaged due to uneven stress, or are ejected out, and the functions of the whole hydraulic electromagnetic valve are influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a hydraulic pressure solenoid valve barrel, can make the spring holder remain throughout at home position under the condition that bears great pressure oscillation and impact force, can not take place the displacement, by ejecting and impaired phenomenon.
In order to solve the technical problem, the utility model discloses a technical scheme be: providing a hydraulic solenoid valve sleeve, wherein the end part of the valve sleeve, which is used for fixing a limiting spring seat, is the front end of the valve sleeve, and the front end of the valve sleeve is gathered in a bag-pleat shape; after the front end of the valve sleeve is gathered, the outer side wall of the front end of the valve sleeve is provided with a plurality of concave parts which are distributed around the axis of the valve sleeve; the concave part is correspondingly provided with a convex part on the inner side wall of the front end of the valve sleeve.
Preferably, the ends of the plurality of lobes opposite the spring seat lie in a common plane and the plane is perpendicular to the axis of the valve sleeve.
Preferably, the outer side of the front end of the valve housing is hemispherical.
Preferably, the front end of the valve housing is hardened by heat treatment.
The utility model has the advantages that: the utility model can keep the spring seat in the original position all the time under the condition of bearing larger pressure oscillation and impact force, and the phenomena of displacement, ejection and damage can not occur; the structure is simple and the assembly is easy.
Drawings
Fig. 1 is a schematic perspective view of a preferred embodiment of a hydraulic solenoid valve housing according to the present invention;
fig. 2 is a schematic cross-sectional view of a hydraulic solenoid valve sleeve according to the present invention;
fig. 3 is a schematic view of a hydraulic solenoid valve housing according to the present invention.
The parts in the drawings are numbered as follows: 1. a valve housing; 2. a recessed portion; 3. a boss portion; 4. a spring seat.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1 to 3, an embodiment of the present invention includes:
the end part of the valve sleeve 1, which is used for fixing and limiting the spring seat 4, is the front end of the valve sleeve 1, and the front end of the valve sleeve 1 is gathered in a bag-pleat shape so as to fix and limit the spring seat 4; after the front end of the valve sleeve 1 is gathered, a plurality of concave parts 2 are arranged on the outer side wall of the front end of the valve sleeve 1, and the plurality of concave parts 2 are distributed around the axis of the valve sleeve 1; the concave part 2 is correspondingly provided with a convex part 3 on the inner side wall of the front end of the valve sleeve 1. The structural design greatly improves the resistance of the spring seat 4 to be ejected out, so that the spring seat can resist pressure oscillation impact in a system, and the position of the spring seat 4 can be kept at the initial position; and the front end of the roll-over valve sleeve 1 does not need to be cut, so that the self structural strength of the front end of the valve sleeve 1 is ensured, and the stress performance is indirectly improved. The ends of the plurality of protrusions 3 opposite to the spring seat 4 are located in the same plane, and the plane is perpendicular to the axis of the valve sleeve 1; can contact with spring holder 4 to the at utmost to in better fixing the restriction to spring holder 4, the steadiness is higher. The outer side of the front end of the valve sleeve 1 is hemispherical, so that the front end of the valve sleeve 1 is better in stress. The front end of the valve sleeve 1 is hardened by heat treatment, so that the structural strength of the valve sleeve 1 is improved.
The utility model can keep the spring seat 4 in the original position all the time under the condition of bearing larger pressure oscillation and impact force, and the phenomena of displacement, ejection and damage can not occur; the structure is simple and the assembly is easy.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
