Abstract
The utility model provides a novel throttle valve---superimposed double one-way throttle valve. A one-way throttle valve of same structure is respectively arranged in two lateral cavities symmetrically on the centerline of a valve. Compared with the existing one-way throttle valve, the double one-way throttle valve has the advantages of small occupied space, convenient installation and maintenance, interchange between the inlet throttle and the outlet throttle, the adoption of spiral connection between the throttle screw and the valve, good sealing performance, effective oil leakage prevention, which is an ideal updated product for one-way throttle valve.
Description
One, technical field
The utility model relates to a kind of throttle valve, goes into F16K15/00.
Two, background technique
Throttle valve is a kind of skeleton symbol flow control valve, and it is to change passage section when utilizing oil stream by throttle valve to regulate flow or change pressure before and after the valve.For one-way throttle valve, when oil stream forward flow, play throttling action, when oil flows when reverse, oil pressure promotes spool, makes spool and valve body formation major path, does not play throttling action, becomes one-way valve.Structural type such as LDF-B1OH, the LDF-LIOH etc. of the present one-way valve of using always, it is big that the valve of this form exists volume, and it is big to occupy the space in group shot, and work has only been flowed throttling action to forward oil, reverse oil flow becomes one-way valve not play throttling action, can't realize bidirectional throttle.
Three, model utility content
The purpose of this utility model is that a kind of two-way equal novel throttling valve that can play throttling action---overlapping Double throttle check valve will be provided, to overcome the defective of one-way throttle valve.This novel overlapping Double throttle check valve can adopt following technological scheme to realize: it is that symmetry is installed two one-way throttle valves compositions on the horizontal axis of valve body, these two mutual structures of one-way throttle valve and mounting type are identical, only be that installation direction must be reverse, can not equidirectionally install.That is to say in the chamber, center line both sides of valve body and respectively adorn an one-way throttle valve that structure is identical symmetrically, and valve body is installed on the base plate forms.Wherein arbitrary one-way throttle valve is made up of valve body, spool, back-up ring, oil sealing, spring, throttling screw and location scale plate.Its medi-spring is put into the throttling screw intermediate cavity, spool is packed in the chamber of valve body, back-up ring is contained in and makes location usefulness in the circlip groove of throttling screw, and oil sealing is screwed into valve body with throttling screw after packing in the oil seal groove on the throttling screw, and on the end face of valve body by screw installing and locating scale plate.The effect one of location scale plate is that throttling screw is played position-limiting action, the 2nd, contents such as indication flow scale are arranged on the scale plate of location.
The overlapping Double throttle check valve of making according to technique scheme is compared its advantage with existing one-way throttle valve and is: 1, to occupy the space smaller for the Double throttle check valve that adopts overlapping structural type to form, installation and maintenance are convenient, can realize that inlet throttle and outlet throttling exchange; Then can realize one-way throttle when 2, only adorning an one-way throttle valve in left and right two chambeies of valve body: 3, throttling screw adopts with valve body and is threaded, and adds oil sealing, prevents the generation of oil impregnate problem effectively.
Four, description of drawings
Fig. 1, overlapping Double throttle check valve structural representation.
Five, embodiment
Overlapping Double throttle check valve of the present utility model can be implemented according to mode shown in Figure 1: as shown in Figure 1, it is respectively to adorn an identical one-way throttle valve of structure symmetrically to form in the chamber, center line both sides of valve body (1).Wherein arbitrary one-way throttle valve is made up of spool (2), back-up ring (3), oil sealing (4), spring (5), throttling screw (6) and location scale plate (7).Its medi-spring (5) is put into throttling screw (6), spool (2) is packed in the chamber of valve body, back-up ring (3) is contained in the circlip groove on the throttling screw (6), oil sealing is screwed into valve body (1) with throttling screw after packing in the oil seal groove on the throttling screw, and will locate scale plate (7) by screw and be fixed on the end face of valve body.When working: when the logical oil in A1 chamber, control the oily flow that the A chamber is arrived in the A1 chamber by regulating throttling screw (6) according to the overlapping Double throttle check valve of said structure composition; When the oil-feed of A chamber, fluid is pushed spool to the left side through the side opening in A chamber, makes fluid straight-through to the A1 chamber from the A chamber.The working principle in B chamber is identical with the A chamber.Base plate (8) itself but provides as accessory not on stacked unidirectional throttle valve, uses when installing for system.
Claims (3)
1, a kind of overlapping Double throttle check valve is characterized in that respectively adorning symmetrically an identical one-way throttle valve of structure and forms in the chamber of the center line both sides of valve body (1).
2, overlapping Double throttle check valve according to claim 1, it is characterized in that one-way throttle valve is made up of spool (2), back-up ring (3), oil sealing (4), spring (5), throttling screw (6) and location scale plate (7), its medi-spring (5) is put into throttling screw (6), spool (2) is packed in the chamber of valve body, back-up ring (3) is contained in the circlip groove on the throttling screw (6), oil sealing is screwed into valve body (1) with throttling screw after packing in the oil seal groove on the throttling screw, and will locate scale plate (7) by screw and be fixed on the end face of valve body.
3, overlapping Double throttle check valve according to claim 1 is characterized in that throttling screw (6) and valve body (1) are by being threaded.
