Abstract
The utility model relates to a throttling pipe joint with a filtering function and solves the technical problems that an existing throttling pipe joint with the filtering function is complex in structure. The throttling pipe joint comprises a pipe joint body with two ends provided with external threads. A diversion hole is arranged in the pipe joint body, a throttling cavity is arranged in an oil inlet end of the diversion hole, and a throttling valve and a filter screen are arranged in the throttling cavity. The filter screen is fixed on a side in the direction, where oil comes, of the throttling valve. Due to the fact that the filter screen is fixedly arranged in the throttling cavity, the throttling pipe joint can filter hydraulic oil passing through the throttling valve and prevent throttling holes from being clogged, and is simple in structure.
Description
Technical field
The utility model relates to a kind of pipe joint, relates in particular to a kind of throttle pipe joint with filtering function.
Background technique
Throttle pipe joint is except having the joint function that connects as pipeline, and its inner throttle valve can play throttling function.But because the aperture of throttle orifice is less, often easily by the foreign matters from being blocked in the hydraulic oil, thereby make throttle pipe joint stop up the forfeiture connectivity capabilities.Existing throttle pipe joint complex structure with filtering function, manufacture cost is higher.
The model utility content
The technical problems to be solved in the utility model is for existing with the baroque shortcoming of the throttle pipe joint of filtering function, and a kind of throttle pipe joint with filtering function simple in structure is provided.
The technical solution adopted in the utility model is: construct a kind of throttle pipe joint, comprise that two ends are provided with externally threaded pipe joint body, establish pod apertures in the pipe joint body, be provided with the throttling chamber in one end of pod apertures, be provided with throttle valve and filter screen in the throttling chamber, filter screen is fixed on the oily direction side of throttle valve.In the utility model, by in the throttling chamber, being fixedly installed filter screen, the hydraulic oil of the throttle valve of flowing through is filtered and realizes preventing that throttle orifice is blocked, and this being simple in structure.
In the utility model, in the throttling chamber, also be provided with plug, be provided with the perforation that is communicated with its both sides in the plug, filter screen is fixed between throttle valve and the plug, by plug filter screen is fixed, and is simple in structure, easily realizes.
In the utility model, the throttling cavity wall is provided with internal thread, and the plug outer wall is established outside thread, and plug and pipe joint are for being threaded.The employing installation plug that is threaded can make things convenient for the installation and removal of plug, realizes the maintenance of pipe joint.The bore a hole cross section of outer side of plug is polygonal, for example is regular polygon.This is easy to use instrument plug is carried out installation and removal.
In the utility model, throttle valve be provided with the groove that holds filter screen between plug contacts, filter screen is arranged in the groove.Plug was with the filter screen extrusion damage after this prevented the plug installation.This groove can be arranged on the end face of the contiguous throttle valve of plug or be arranged on the end face of the contiguous plug of throttle valve.
In the utility model, pod apertures is stepped, and its enlarged diameter section is the throttling chamber, and this can make things convenient for the installation of throttle valve, by can easily realizing the fixing of throttle valve at the plug in the throttle valve outside.
The beneficial effect that the utility model compared with prior art has is: simple and reliable for structure, easy installation and removal is convenient to safeguard.
Description of drawings
Fig. 1 is the structural representation of the utility model throttle pipe joint.
Reference character:
Pipe joint body 1, throttle valve 2, filter screen 3, plug 4.
Embodiment
Below in conjunction with the description of drawings specific embodiments.
As shown in Figure 1, throttle pipe joint in the present embodiment comprises pipe joint body 1, its two ends are provided with outside thread, be used for being connected with the pipe fitting screw thread that is connected, in pipe joint body 1, establish stair-stepping pod apertures, the enlarged diameter section of pod apertures is the throttling chamber, is disposed with plug 4, filter screen 3, throttle valve 2 in the throttling chamber from the oil inlet end of pipe joint body.The throttling cavity wall is provided with internal thread, and plug 4 outer walls are established outside thread, and plug 4 is threaded with outside thread by the internal thread that cooperatively interacts with pipe joint body 1, and throttle valve 2 is fixed in the throttling chamber.The end face that closes on throttle valve 2 at plug 4 is provided with the groove that holds filter screen 3, filter screen 3 is contained in the groove, perforation is set in that plug 4 is interior, this perforation so that hydraulic oil can be flowed through, filter 23, throttle valve 2 and be communicated with oil-feed and the fuel-displaced two ends of throttle pipe joint.The cross section of perforation outboard end is regular hexagon, is rendered as inner hexagonal hole, in order to can make things convenient for installation and removal by tool using.
Claims (7)
1. throttle pipe joint, comprise that two ends are provided with externally threaded pipe joint body, establish pod apertures in the pipe joint body, be provided with the throttling chamber in one end of pod apertures, throttling is provided with throttle valve in the chamber, it is characterized in that being provided with filter screen in the throttling chamber, described filter screen is fixed on the oily direction side of throttle valve.
