Abstract
The utility model relates to an overflow valve for preventing pressure pulsation impact. The overflow valve comprises a spring cover assembly (1), a valve core assembly (2), a damping rod (3), a damping spring (4) and a valve body and valve seat assembly (5), wherein the spring cover assembly (1), the valve core assembly (2), the damping rod (3), and the damping spring (4) are arranged on the valve body and valve seat assembly (5). The utility model has the advantages of compact structure, small size and convenient installation, and can prevent the pressure pulsation impact.
Description
Technical field
The utility model belongs to the hydrovalve field, particularly relates to a kind of relief valve that prevents that pressure pulsation from impacting.
Background technique
There are the following problems for used direct-acting overflow valve in the present hydraulic system:
System pressure is because the actuator function influence produces pressure pulsation impacts, and relief valve spool is influenced by this to open suddenly, and moment open amount bigger, reduce opening subsequently again rapidly even close, and so forth more repeatedly.Spool or valve seat are fragile after long-time like this, and whole valve vibration can occur and produce noise when serious.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of relief valve that prevents that pressure pulsation from impacting, to solve existing technical problem.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of relief valve that prevents that pressure pulsation from impacting is provided, comprise spring shield assembly, mangetic core assembly, damper rod, damping spring and valve body and valve seat assembly, described spring shield assembly, mangetic core assembly, damper rod, damping spring are installed on the valve body and valve seat assembly.
Beneficial effect
The utility model compact structure, volume is small and exquisite, and it is convenient to install, and can prevent the pressure pulsation impact.
Description of drawings
Fig. 1 is the utility model sectional view.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, described spring shield assembly 1, mangetic core assembly 2, damper rod 3, damping spring 4 are installed on the valve body and valve seat assembly 5.
