Abstract
The utility model discloses a composite high-speed air inlet and outlet valve. A valve cover 3 is connected with a valve body 10 by a bolt; a large sealing pad 5 is arranged between the valve cover 3 and the valve body 10; the middle position of the valve cover is provided with a valve stem sleeve 1; a guide shaft 4 is arranged in the valve stem sleeve 1; the lower end of the guide shaft 4 is provided with a lifting cover 6; a floating body 7 is arranged in a floating body cover 8; the upper end of the floating body 7 is provided with a small sealing pad 2; the lower end of the floating body is provided with a pad 9; and the external edge wall of the valve cover 3 is provided with a plurality of air inlets and outlets. By adopting the structure, the pressure in the pipeline can be adjusted, and the destroy function of the water hammer is prevented effectively.
Description
Technical field
The utility model relates to a kind of valve, exactly is a kind of combined high-speed air inlet and exhaust valve.
Background technique
Original outlet valve air displacement is little, easily leaks, and the intake and exhaust weak effect, complex structure, volume is big, increases cost, installs inconvenient.
Summary of the invention
The purpose of this utility model is that a kind of combined high-speed air inlet and exhaust valve is provided, and it is big that this valve can reach air displacement, has increased anti-water hammer function, and compact structure is in light weight, long service life, safe and reliable purpose.
For reaching above purpose, the utility model valve gap is connected by bolt with valve body, between valve gap and valve body, be provided with the big sealing gasket of air inlet and exhaust valve, intermediate portion at valve gap is provided with valve stem casing, and the axis of guide is located in the valve stem casing, is provided with the lifting cover in the lower end of the axis of guide, buoyancy aid is located in the floating-body cover, the upper end of buoyancy aid is provided with little sealing gasket, and the lower end of buoyancy aid is provided with liner, is provided with a plurality of ports on the perimeter wall of valve gap.
By above setting, the utility model is installed on the pipeline, buoyancy aid can move up and down under the effect of the axis of guide, and the gas circuit of whole valve body is carried out break-make control, to adjust the pressure in the pipeline at any time, when ambient pressure during greater than manifold pressure, buoyancy aid sinks, and extraneous air enters in the pipeline by port; When the pressure in the external world during less than manifold pressure, buoyancy aid rises, and valve body is closed, and to adjust the pressure in the pipeline, has effectively prevented the destruction of water hammer.
