Abstract
The utility model discloses a filter type straight joint, which consists of a straight joint body and a filter screen. The filter screen is pressed inside a thread of the straight joint connected with a body of a pilot actuated valve to prevent sewage from entering the pilot actuated valve to block a valve core. The filter type straight joint has the advantages of high reliability, low cost and small space occupancy, and is convenient to install, use and maintain, and has broad application.
Description
Technical field
This filtering type straight joint is applied to hydraulic shovel guide control system, belongs to the control gear technical field.
Background technique
In guide's control system of hydraulic shovel, guide's filter connects with hydraulic oil pipe between each pilot-actuated valve, being difficult to assurance in the installation of excavator, maintenance process has pollutant anything but and enters hydraulic pipe line, in case and these pollutants finally enter pilot-actuated valve and just cause pilot-actuated valve spool clamping stagnation most probably, thereby cause security incident.
Summary of the invention
The purpose of this utility model is to provide a kind of straight joint and pilot-actuated valve valve body connecting thread inside to be pressed into a filter screen with special process, can prevent " pollutant enters pilot-actuated valve and causes pilot-actuated valve spool clamping stagnation ", simple in structure, filtering type straight joint easy to manufacture, easy to install.
Technical solution of the present utility model is such, and a kind of filtering type straight joint comprises straight joint body, filter screen.It is characterized in that straight joint body and pilot-actuated valve valve body connecting thread one end installation filter screen.
Filter screen is installed in the interior bore ends of straight joint body and pilot-actuated valve valve body connecting thread end.
The utility model has the advantages that: be pressed into a filter screen at straight joint and pilot-actuated valve valve body connecting thread inside with special process, prevent that pollutant from entering control valve, cause having of control valve spool clamping stagnation simple in structure, easy to use, cost is low, and is safe and reliable.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is an overall structure plan view of the present utility model.
Fig. 2 is that oil circuit of the present utility model connects application principle figure.
Among Fig. 1～Fig. 2, straight joint body (1), filter screen (2).
Embodiment
The mode of execution of this filtering type straight joint is such: attach it to the filler opening of pilot-actuated valve, reconnect the hydraulic oil pipe of coming from guide's filter, thereby form a complete control system, this sample filtering type straight joint just can play a role.At straight joint body (1) and pilot-actuated valve valve body connecting thread end filter screen (2) is installed, available formula or the open flume type inserted opened hole countersunk filter screen (2) is installed, and also can directly at end face filter screen (2) be installed, but should fix.Installation is fine like this, prevents that dirt from entering pilot-actuated valve spool clamping stagnation, thereby avoids causing security incident.
Claims (2)
1. a filtering type straight joint comprises straight joint body, filter screen, it is characterized in that straight joint body (1) and pilot-actuated valve valve body connecting thread one end installation filter screen (2).
2. according to the described filtering type straight joint of claim 1, it is characterized in that filter screen (2) is installed in the interior bore ends of straight joint body (1) and pilot-actuated valve valve body connecting thread end.
