Abstract
The utility model discloses a one-way throttle valve, belongs to a hydraulic protective element, and aims to provide a throttle valve which has a simple structure and conveniently adjusts pressure. The throttle valve consists of a valve body with a valve cavity, and a valve core arranged in the valve cavity, wherein an oil inlet (8) and an oil outlet (9) which are communicated with the valve cavity (10) are formed on the valve body (7); the valve core consists of a plug (3) which is fixed on the valve body (7) and seals the valve cavity (10), a valve (6) which is arranged in the valve cavity (10) and has a sleeve structure, a spring (4) arranged between the plug (3) and the valve, and an adjusting screw rod (2) which is fixed on the plug (3), stretches into the valve cavity (10) and is matched with the valve (6); and an oil hole (5) communicated with the valve cavity (10) is formed in the valve (6). The throttle valve has the advantages that the throttle valve has a simple structure, conveniently adjusts the pressure, and the like; and the throttle valve can be used for controlling the pressure of a pipeline in a hydraulic system.
Description
Technical field
The utility model relates to a kind of hydraulic element, relates in particular to a kind of one-way throttle valve.
Background technique:One-way throttle valve is a kind of hydraulic protecting element that is used for pilot pressure in the hydraulic system.At present, widely used one-way throttle valve exists complex structure, pressure to regulate defectives such as inconvenience.
Summary of the invention:In order to overcome the defective that exists in the existing technology, the utility model aims to provide a kind of simple in structure, one-way throttle valve that pressure is easy to adjust.
To achieve these goals, the utility model adopts following technological scheme: it is made up of the valve body that is provided with valve pocket, the spool that is located in the said valve pocket; Valve body is provided with filler opening and the oil outlet that is communicated with valve pocket; Said spool is by being fixed on the valve body the plug of valve pocket sealing, being located at the valve that is sleeve-like structure in the valve pocket, being located at spring between plug and this valve, being fixed on and stretching into the adjusting screw rod that cooperates with valve in the valve pocket on the plug and constitute, and valve is provided with the oilhole that is communicated with valve pocket.
Compare with existing technology; The utility model has changed valve into sleeve-like structure, and in spool, has increased adjusting screw rod owing to adopted technique scheme; Therefore can regulate the aperture of oilhole with the degree of depth that cooperates of valve through the regulating and controlling screw rod, thereby realize pressure control easily.The utlity model has advantages such as simple in structure, that pressure is easy to adjust.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure: locking nut 1 adjusting screw rod 2 plugs 3 springs 4 oilholes 5 valve 6 valve bodies 7 filler openings 8 oil outlets 9 valve pockets 10
Embodiment:Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1: be provided with valve pocket 10 in the valve body 7, the oil outlet 9 that is located at the filler opening 8 of valve body 7 right-hand members and is located at this valve body bottom is communicated with valve pocket 10, is provided with spool in the valve pocket 10; Said spool by be fixed on through screw thread on the valve body 7 and with the plug 3 of valve pocket 10 sealings, be located at the valve 6 that is sleeve-like structure in the valve pocket 10, be located at spring 4 between plug 3 and this valve, be fixed on the plug 3 and stretch into the adjusting screw rod 2 that cooperates with valve 6 in the valve pocket 10 through screw thread and constitute, valve 6 is provided with the oilhole 5 that is communicated with valve pocket 10.Loosening for fear of adjusting screw rod 2, on adjusting screw rod 2, be provided with locking nut 1.
