摘要： A stop valve capable of reducing generation of noise and a valve body can surely close a valve seat even if a float is inclined. The stop valve has a case, a float provided in the case so as to move vertically, wherein a valve seat is closed by a valve body when the float moves upward while the valve seat is open when the float moves downward, a pedestal provided under the case for placing a spherical weight thereon, characterized in that the pedestal has radial slits thereon and the float has radial slits at the bottom wall thereof.

摘要： In a control valve for permitting a valve to open when pressure applied to the valve exceeds a given value so as to escape a given flow rate through a gap defined around the valve, it prevents the valve from floating between a valve seat and a stopper and prevent the valve from striking against the valve seat, the inner surface of a casing and a stopper, thereby preventing the production of noise. The gap defined between the periphery of the valve and a casing is set to be small while the velocity V of the fluid flowing through the gap is increased so as to increase resistance force operating on the valve, whereby the valve always contacts the stopper whenever the valve is opened. There is provided a fluid passage through which fluid passes inside and outside the valve for compensating the flow rate which corresponds to the reduced flow rate caused by the reduction of the gap.
摘要翻译：在用于允许阀施加到阀上的压力超过给定值以便通过限定在阀周围的间隙逃避给定流量的阀门的控制阀中时，其阻止阀在阀座和止动器之间浮动，并且防止阀门撞击阀座，壳体的内表面和塞子，从而防止产生噪音。限定在阀的周边和壳体之间的间隙被设定为小，同时流过间隙的流体的速度V增加，以增加在阀上操作的阻力，由此，只要阀阀打开。提供了一个流体通道，液体通过该流体通过阀门内部和外部，用于补偿对应于由间隙减小引起的减小的流量的流量。
