Abstract
Disclosed is an automatic constant pressure vent valve applicable for constant pressure automatic air exhaust of fluid systems, which comprises a valve, a buoy, a buoy ball, a valve lid, a sealing ring, a spring, a jack block and the like, and is characterized in that the top outlet of the valve lid (1) is communicated with atmosphere, the buoy (10) is arranged between the valve lid (1) and the valve (16), the buoy (10) is internally provided with a check ring (5), sealing rings (6), and (8), a buoy upper lid (9), the buoy ball (11), the sealing ring (12), a buoy lower lid (13), the sealing ring (14) and a check ring (15); the jack block (2) and the spring (3) are arranged between the buoy (10) and the valve lid (1); the sealing ring (7) is arranged between the buoy (10) and the valve (16); the valve (16) is provided with an air inlet, thus forming the automatic constant pressure vent valve.
Description
Technical field: a kind of automatic constant pressure outlet valve is applicable to the level pressure automatic vent of liquid system.
Background technique: existing outlet valve, complex structure, working pressure is low, and poor sealing performance influences the sealing of system, opens the disposable exhaust of pipeline when adopting debugging, influence system sealing, and exhaust effect is bad, and efficient is low.
Summary of the invention: the utility model automatic constant pressure outlet valve provides a kind of can realize automatic constant pressure, automatic control pressure vent, make system works steady, the efficient height, and can solve existing equipment because there is gas in liquid system, cause the performance element shake, it is asynchronous to work, and the system that influences is by pre-provisioning request work.
The utility model automatic constant pressure outlet valve can be realized by following measure: a kind of automatic constant pressure outlet valve, form by valve body, floating drum, ball float, spring, seal ring, exhaust port, it is characterized in that: the outlet of body cap upper end communicates with atmosphere, and floating drum is housed between the valve body, is equipped with in the floating drum to be equipped with between back-up ring, seal ring, floating drum loam cake, ball float, seal ring, floating drum lower cover, seal ring, back-up ring, floating drum and the body cap and seal ring, valve body are housed between jacking block, spring, floating drum and the valve body are provided with inlet hole, constitute the automatic constant pressure outlet valve.
The utility model has following characteristics compared to existing technology:
1, adopt floating drum ball float structure, floating drum moves up and down in valve body has certain storing function, improves exhaust efficiency;
2, ball float can adapt to different systems according to different fluids and working pressure design, and is applied widely;
When 3, system pressure is too high for some reason, can open outlet valve automatically, realize automatic protection functions, and in working pressure, can set to have adaptability preferably;
4, can be installed in the system as a functional part and use, also can be used as an exhaust instrument and use;
5, this valve arrangement is simple, Maintenance free, cost performance height.
Description of drawings:
Fig. 1 is the structural representation of the utility model automatic constant pressure outlet valve
Embodiment: the utility model automatic constant pressure outlet valve embodiment is further described below in conjunction with accompanying drawing:
The automatic constant pressure outlet valve is made up of valve body, floating drum, ball float, spring, seal ring, exhaust port.It is characterized in that: the outlet of body cap 1 upper end communicates with atmosphere, and floating drum 10 is housed between the valve body 16, back-up ring 5, seal ring 6,8, floating drum loam cake 9, ball float 11, seal ring 12, floating drum lower cover 13, seal ring 14, back-up ring 15 are housed in the floating drum 10, jacking block 2, spring 3 are housed between floating drum 10 and the body cap 1, between floating drum 10 and the valve body 16 seal ring 7 is housed, valve body 16 is provided with inlet hole, constitutes the automatic constant pressure outlet valve.Floating drum 10 can slide up and down in valve body 16, the floating drum loam cake 9 of ball float 11 in floating drum 10 and the import and export sealing of floating drum lower cover 13.Be provided with spring 3 and jacking block 2 between floating drum loam cake 9 and the body cap 1, spring pressure can be set.Have exhaust port at jacking block 2 middle parts and side, the aperture of automatic constant pressure outlet valve upper discharge hole prevents the inefficacy of outlet valve greater than the aperture of valve body 16 inlet holes.The proportion of ball float 11 is less than the proportion of fluid, ball float 11 bear the working pressure of pressure greater than valve body 16.Frictional force may command between floating drum 10 and the valve body 16.Spring 3 on the valve body 16 is exactly an outlet valve after cancelling with jacking block 2.
