Abstract
The utility model relates to a check valve without resistance. The structure of a balance weight hammer is changed on the basis of the existing micro-resistance slow closing check valves. Thus, the weight of the balance weight hammer can be changed following the starting and the stop of a pump, and a valve plate can be started and closed through the differential value between the gravitational moment of the balance weight hammer and the gravitational moment of the valve and the action force of a water head. The check valve fully eliminates the resistance generated by the gravity of the valve plate for fluid and has better energy saving.
Description
Described in the utility model is a kind of without hindrance buffer valve.
" Tiny Drag Slow Shut Check Valves " that CN89205900.1 provides is owing to adopt the Slow Close system, has outstanding effect aspect elimination water hammer, the damping, when opening alleviating, the counter weight that is provided with on it resistance that aqueous fluid produces is had certain effect, than the Swing check valve good energy-conserving effect because of valve plate gravity.But the counter weight weight of this valve is definite value, therefore can not overcome the resistance that valve plate weight convection cell produces fully, and energy-saving effect is restricted.
It is a kind of on the basis of above-mentioned safety check that the purpose of this utility model is to provide, and only changes the weight member structure and thoroughly eliminate the safety check of check valve plate gravity to the resistance of aqueous fluid generation.
The technical solution of the utility model is: safety check keeps the structure of the gentle locking mechanism of existing valve body, and existing counter weight is become the counterweight structure that its counterweight weight changes with the water pump start and stop.Utilize difference and head active force between counterweight gravitational moment and the valve plate gravitational moment to open and close valve plate.Counter weight is by the counterweight spherical shell, one end is connected with the counterweight spherical shell, and the other end is packed in the hollow weight linear meter in the valve plate rotating shaft, stream guiding tube that is connected with weight linear meter and flow-guiding valve, the withstand voltage aerating ballon that is positioned at the counterweight spherical shell constitutes, and flow-guiding valve is connected with valve body by pod apertures.Counter weight still is positioned at outside the valve body as prior art and is fixed in the valve plate rotating shaft, and forms an obtuse angle with valve plate on the transversal projection plane of rotating shaft.During termination of pumping, the counterweight gravitational moment is slightly less than the valve plate gravitational moment, and the gas pressure in the withstand voltage aerating ballon is a little less than the safety check fluid operating pressure.When water pump operation reaches certain working pressure, enter a certain amount of water in the counterweight spherical shell, balloon is gradually reduced, volume-diminished, air pressure increases, and the weight of counter weight increases gradually, and the counterweight gravitational moment is gradually greater than the valve plate gravitational moment, when air pressure in the Pressure-proof balloon and hydraulic balance, no longer water inlet in the counterweight spherical shell, counter weight weight reaches design maximum, so under the effect of counter weight gravitational moment and head active force, drive rotating shaft rotation, valve plate fixed thereon is also opened thereupon.When termination of pumping, valve interior fluid pressure falls suddenly, and water is discharged fast by the balloon pressure compression in the counterweight spherical shell, makes the counter weight gravitational moment gradually less than the valve plate gravitational moment, adds the effect of refluence body again, and valve plate reaches closed condition automatically.As from the foregoing, the keying of valve plate is to realize by difference between counterbalance moment and the valve plate gravitational moment and head active force, thereby valve plate weight convection cell does not produce drag effect.
The utility model is owing to change counter weight into counterweight structure that its counterweight weight changes with the water pump start and stop, valve plate opens and closes by difference between counterbalance moment and the valve plate gravitational moment and head active force and realizes, thereby the resistance that safety check gravity convection body produces, good energy-conserving effect have been eliminated fully.
