Abstract
The utility model discloses an external pneumatic cylinder buffering exhaust apparatus, it comprises valve body, check valve, choke valve, discharge valve and pressure measurement joint, and check valve, choke valve and discharge valve assemble in the valve hole of valve body, have the hydraulic fluid port on the valve body, and the hydraulic fluid port links to each other with cushion chamber, the hydraulic fluid port chamber of pneumatic cylinder respectively. The external hydraulic cylinder buffering and exhausting device is an independent component and can be directly installed on the outer surfaces of the cylinder head and the cylinder bottom of the hydraulic cylinder to realize the buffering and exhausting functions of the hydraulic cylinder. Compared with the currently adopted buffering exhaust device which directly processes valve holes on the cylinder head and the cylinder bottom of the hydraulic cylinder, the buffering exhaust device can effectively improve the production efficiency of manufacture, reduce the manufacture quality cost and has the condition of forming a standardized product.
Description
Technical field
The utility model belongs to technical field of hydraulic elements, relates in particular to a kind of external oil hydraulic cylinder buffering venting gas appliance.
Background technique
Traditional oil hydraulic cylinder buffering venting gas appliance be on the cylinder head of oil hydraulic cylinder and cylinder bottom directly work sheet and load onto one-way valve, throttle valve and outlet valve to valve opening, throttle bore and air release valve hole, realize the buffering degassing function of oil hydraulic cylinder.The size of unidirectional valve opening, throttle bore and air release valve hole is all less, and accuracy of manufacturing requires higher relatively, and the size of the cylinder head of oil hydraulic cylinder and cylinder bottom is bigger, and weight is heavier relatively, and accuracy of manufacturing requires relatively low.Therefore during fabrication, in order to process this several little valve openings, often need bigger and the higher relatively equipment of precision, manufacturing efficiency is low, the cost height, in case process quality issue occurs, mass loss is also bigger.
The model utility content
Technical problem to be solved in the utility model is, design and a kind of unidirectional valve opening, throttle bore, air release valve hole and one-way valve, throttle valve, outlet valve are assembled independent parts, and be directly installed on the cylinder head of oil hydraulic cylinder and the external oil hydraulic cylinder buffering venting gas appliance of cylinder bottom outer surface.
The technological scheme that solution the utility model technical problem is adopted is:
External oil hydraulic cylinder buffering venting gas appliance comprises valve body, one-way valve, throttle valve, outlet valve and pressure measuring tie-in, and described one-way valve, throttle valve and outlet valve are assemblied in the valve opening of valve body.Described buffering venting gas appliance, the cylinder head that is installed in oil hydraulic cylinder is or/and the outer surface of cylinder bottom.
Three hydraulic fluid ports are arranged on described valve body, and wherein two hydraulic fluid ports link to each other with the buffer cavity of oil hydraulic cylinder, another hydraulic fluid port links to each other with the hydraulic fluid port chamber of oil hydraulic cylinder.
Described pressure measuring tie-in links to each other with check valve assembly, pressure-detecting device by with being connected of pressure measuring tie-in, can monitor the pressure of the buffer cavity of oil hydraulic cylinder.
Further be, described one-way valve, throttle valve and outlet valve all are contained in the same valve body, form a buffering venting gas appliance, have at least two such buffering venting gas appliance to be installed in the cylinder head and the cylinder bottom outer surface of oil hydraulic cylinder respectively in the use.
Further be, two valves or a valve in described one-way valve, throttle valve and the outlet valve are contained in the valve body, form two or three and independently cushion venting gas appliance, such buffering venting gas appliance is installed in the cylinder head and the cylinder bottom outer surface of oil hydraulic cylinder respectively in the use.
The utlity model has following obvious advantage:
After using this device of external oil hydraulic cylinder buffering venting gas appliance, do not need on the cylinder head of oil hydraulic cylinder and the cylinder bottom to process described valve opening, and only need process oil through.
External oil hydraulic cylinder buffering venting gas appliance, compact structure, volume is little, and is in light weight, be installed in the outer surface of the cylinder head of oil hydraulic cylinder and cylinder bottom after, to the almost not influence of profile installation dimension of oil hydraulic cylinder.Several specification series can be unified or form to the specification of this device, adapts to produce in batches, possesses the condition that forms standard product.Owing to need on the cylinder head of oil hydraulic cylinder and cylinder bottom, not process valve opening, therefore, can enhance productivity, can reduce production costs again and quality risk.
