Abstract
The utility model relates to a simple throttling valve, relating to a throttling valve. The simple throttling valve comprises a lock nut, a disk spring, a gasket and a throttling orifice. The simple throttling valve is characterized in that the throttling orifice is arranged in a valve body; the throttling orifice is a round steel plate; a round hole is arranged in the middle of the throttling orifice; a plurality of small holes are arranged on the periphery of the round hole; the gasket is arranged on the throttling orifice; a round hole is arranged in the middle of the gasket; the disk spring is arranged on the gasket; and the lock nut is arranged on the disk spring. The simple throttling valve is simple and compact in structure, easy to process, stable and reliable in performance, convenient to use and maintain, and low in cost.
Description
Technical field
The utility model relates to a kind of throttle valve, and particularly a kind of simple and easy throttle valve is applied to ship hydraulic mechanism.
Background technique
Since China's reform and opening-up, national economy increases fast, and " scientific and technical innovation, autonomous innovation " become the main flow of current industrial development, and China's industry progressively develops to the direction of intensive style, energy-saving and emission-reduction, low-carbon (LC).Throttle valve is a kind of device of the movement velocity of the control actuating component in the hydraulic jack.Be installed in the end of oil cylinder, thereby when changing throttling cross section or chock length and make piston rod movement arrive stroke terminal with the control fluid flow, impact force reduces.The medium-and-large-sized hydraulic jack working strength of boats and ships is big, and the structural design of throttle valve is the key that prevents that the oil cylinder piston bar from damaging even exploding cylinder.In order to address this problem; R&D institution and science and technology in enterprise personnel in constantly research, explore, utilize modern science and technology, existing throttle valve is improved and innovates; Though obtained some progress technically, in practice, still existed the technical barrier that does not overcome as yet.
Summary of the invention
The purpose of the utility model is to overcome above deficiency, and a kind of simple and easy throttle valve is provided, through cooperating between throttling oilhole and the pad; Make oil-feed smooth and easy; Meter out can let the piston rod slowly land, and impact force reduces; Avoid the damage of piston rod, and prevent that pipelines from bursting from causing the generation of unexpected accident.
The utility model solves the technological scheme that its technical problem adopted: contain locking nut, belleville spring, pad, restricting orifice, be provided with restricting orifice in the valve body, restricting orifice is a circular steel plate; The centre is provided with a circular hole, and the border is provided with several apertures, and restricting orifice is provided with pad; Be provided with a circular hole in the middle of the pad; Pad is provided with belleville spring, and belleville spring is provided with locking nut, has formed whole simple and easy throttle valve.
The know-why that the utility model adopts is: in the hydraulic jack oil-feed, fluid is porose through the institute of restricting orifice, and oil inlet passage is smooth and easy.When the hydraulic jack oil return, restricting orifice is adjacent to pad under the effect of pressure, and the aperture of border all is plugged; Fluid passes through from middle aperture only; Play throttling action, made the piston rod slowly land, reduced impact force; Prevent to cause pipelines from bursting to cause unexpected accident, prolong oil cylinder working life owing to pressure is excessive.
The utility model beneficial effect is: this valve makes oil-feed smooth and easy, meter out through cooperating between throttling oilhole and the pad; Can let the piston rod slowly land; Avoid the damage of piston rod, help the stability of oil cylinder, prevent to cause pipelines from bursting to cause unexpected accident owing to pressure is excessive.It is simple in structure, and compactness is prone to processing, and is stable and reliable for performance, and working service is convenient, and is with low cost.
Description of drawings
Be to combine accompanying drawing and embodiment that the utility model is further described below:
Fig. 1 is simple and easy throttle valve structure cut-away view;
Fig. 2 is the restricting orifice plan view.
In the drawings: 1 locking nut, 2 belleville springs, 3 pads, 4 restricting orifices.
Embodiment
In Fig. 1, Fig. 2, be provided with restricting orifice 4 in the valve body, restricting orifice 4 is circular steel plates; The centre is provided with a circular hole, and the border is provided with several apertures, and restricting orifice 4 is provided with pad 3; Be provided with a circular hole in the middle of the pad 3; Pad 3 is provided with belleville spring 2, and belleville spring 2 is provided with locking nut 1, has formed whole simple and easy throttle valve.
This simple and easy throttle valve in the hydraulic jack oil-feed, fluid through restricting orifice 4 the institute porose, oil inlet passage is smooth and easy.When the hydraulic jack oil return, restricting orifice 4 is adjacent to pad 3 under the effect of pressure, and the aperture of border all is plugged; Fluid passes through from middle aperture only; Play throttling action, made the piston rod slowly land, reduced impact force; Prevent to cause pipelines from bursting to cause unexpected accident, prolong oil cylinder working life owing to pressure is excessive.
