Description

Ball check valve capable of being opened and closed quickly

Technical Field

The application belongs to the technical field of valves, and more specifically relates to a ball check valve that opens and shuts fast.

Background

The check valve is a valve in which a valve flap automatically opens or closes a channel by means of thrust generated by medium flow to prevent the medium from flowing backwards, and is mainly used for a pipeline in which the medium flows in one direction and only allows the medium to flow in one direction to prevent accidents. The ball check valve is a check valve using a ball as a valve clack, and the principle is that under the action of thrust generated by medium flow, the ball valve clack can roll on a slide way in a valve body along a set direction, so that the effect of opening or closing the valve is realized through the ball valve clack. When the ball check valve works normally, fluid flows from the inlet side to the outlet side; when the pressure at the inlet side is lower than that at the outlet side, the valve clack automatically closes under the action of fluid pressure difference, self gravity and other factors to prevent the fluid from flowing backwards.

However, the existing ball check valve is slow in action, and has time difference in opening and closing, so that the check efficiency is not high.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The first embodiment is as follows: referring to fig. 1-8, a quick-opening/closing ball check valve includes a valve body 1 and a ball 2.

The valve body 1 includes a water pipe 101 and a ball pipe 102.

The spherical pipe 102 and the water pipe 101 are arranged in a crossing and penetrating manner, and the crossing part 106 is the crossing part of the spherical pipe 102 and the water pipe 101.

The lower end of the ball pipe 102 is positioned in the water pipe 101, and the ball pipe 102 penetrates through the upper wall of the water pipe 101 and is positioned on the upper side of the water pipe 101.

The intersection 106 is an open structure, and communicates the sphere pipe 102 with the inside of the water pipe 101.

The ball pipe 102 is obliquely arranged relative to the water pipe 101, the ball pipe 102 is deviated to the left side of the water pipe 101, and the ball pipe 102 is oblique, so that the ball 2 can be conveniently lifted up and fall down.

The lower end of the sphere pipe 102 is flush with the lower end of the water body pipe 101, so that the pipe diameter of the cross part 106 is not smaller than that of the water body pipe 101, the generation of a Venturi effect is effectively avoided, the flow velocity of water flowing through the sphere 2 is increased, the adsorption force is generated on the sphere 2, the sphere 2 is not obviously lifted, and a reverse effect is generated.

The pipe diameter of the cross part 106 is larger than the outer diameter of the ball body 2, a gap is reserved between the ball body 2 and the water body pipe 101, when the water flows back, the water flow on the upper side of the ball body 2 can smoothly flow back into the water body pipe 101, and only air is reserved on the upper side of the ball body 2, so that the opening operation in the next positive flow is facilitated.

The pipe diameter of the water body pipe 101 is smaller than that of the ball body pipe 102, so that the ball body 2 only moves in the ball body pipe 101, and the ball body 2 is prevented from sliding out and falling into the water body pipe 101 to block the water body pipe 101.

A connecting pipe 103 is fixedly connected between the upper end of the water body pipe 101 and the upper end of the ball pipe 102.

Connecting pipe 103 is with the inside intercommunication of spheroid pipe 102 and water pipe 101, and when just flowing, connecting pipe 103 reduces spheroid pipe 102 internal gas pressure with the air escape of spheroid 2 upside for spheroid 2 lifts the speed, and when the backward flow, rivers flow back to spheroid pipe 102 in through connecting pipe 103, oppresses spheroid 2, accelerates spheroid 2's falling speed.

The connecting pipe 103 is positioned at the left side of the sphere pipe 102, so that the sphere pipe 102 is closer to the connecting pipe 103, the medium flow path in the connecting pipe 103 is shorter, and the influence speed on the movement of the sphere 2 is increased.

The pipe diameter of the connecting pipe 103 is smaller than that of the water pipe 101, and when the water flows back, the water flow can rapidly flow into the sphere pipe 102, so that the feedback of the sphere 2 is more sensitive.

The inner wall of the water pipe 101 is provided with a Venturi ring 104, the Venturi ring 104 is located on the lower end opening periphery side of the connecting pipe 103, the Venturi ring 104 and the connecting pipe 103 are closer, when positive flow occurs, pressure difference is generated on the left side and the right side of the Venturi ring 104, suction is generated on the left side of the Venturi ring 104, medium in the connecting pipe 103 can be sucked and flows out, and the closer distance between the Venturi ring 104 and the connecting pipe 103 is, the larger influence on the medium is.

Spheroid 2 is hollow steel ball, and density is greater than water, prevents effectively that the spheroid from meeting water automatic floating, loses the effect of backward flow stagnant water, and inside hollow weight reduction increases rivers to spheroid 2's promotion effect, and 2 outside covers of spheroid have the gum cover, effectively avoid the collision damage of spheroid 2 when the motion.

The diameter of the sphere 2 is matched with the diameter of the sphere pipe 102, and the sphere 2 is positioned in the sphere pipe 102 and is connected with the sphere pipe 102 in a sliding way.
