Abstract
An automatic pipeline leakage protection device is a protection device for automatically closing a pipeline rapidly when the flow of fluid in a pipeline is overloaded. The automatic pipeline leakage protection device mainly comprises a valve seat, a valve body, ball head push rods, pressure springs, glands, a returning ejector rod and a connecting tube, wherein when the flow of the pipeline is overloaded, the pressure difference between the two ends of the valve body surpasses the resistance of the ball head push rods acting on the valve body, the valve body moves towards the outlet direction of the valve seat, the ball head push rods move outwards along axes of the ball head push rods, included angles between the directions of acting forces of the ball head push rods on the valve body and the direction opposite to the moving direction of the valve body are increased, the resistance of the ball head push rods to the movement of the valve body is reduced, and the sealing conical surface of the valve body is rapidly adhered to the sealing conical surface of the connecting tube, so that rapid automatic closing of the protection device is achieved. The automatic pipeline leakage protection device is simple in structure, high in safety and reliability and quick in response.
Description
Technical field
The present invention relates to a kind of fluid line and leak automatic safety device, be particularly useful for the leakage of line fluid, as the protective gear can automatically closed rapidly when pipeline burst leaks.
Background technique
Though existing fluid line leaks automatic safety device various structures, be all utilize multiple valve and complicated rotating mechanism to realize pipeline flow overload protection, all there is the defects such as complex structure, security and stability is poor, reaction is not rapid.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of pipe leakage automatic safety device for the deficiencies in the prior art.
The technical solution adopted in the present invention is: a kind of pipe leakage automatic safety device is formed primarily of valve seat, valve body, bulb push rod, pressure spring, gland, return push rod, connecting tube.Valve body be multidiameter shaft that diameter does not wait be arranged on valve seat circular hole in and the circular hole of maximum diameter position and valve seat be slidably matched, the circumference radial direction of valve seat evenly arranges several hole, arranges a bulb push rod in each hole, a pressure spring, a gland.Valve body maximum diameter position radial direction arranges groove and axially arranges several through hole, and the bulb of bulb push rod contacts with groove.By this; when fluid pipe-line overload; the pressure difference at valve body two ends exceedes the resistance that bulb push rod acts on valve body; valve body moves to valve seat outlet end; bulb push rod moves outside the axis of bulb push rod simultaneously, and the reciprocal angle of bulb push rod to the force direction of valve body and valve body increases, and bulb push rod reduces the moving resistance of valve body; valve body rapidly and connecting tube fit, realize protective gear and automatically close rapidly.
Its degree of depth of groove of the valve body radial direction setting of pipe leakage automatic safety device is less than the Probe-radius of bulb push rod, otherwise self-locking pipe leakage automatic safety device can not work by bulb push rod.
The connecting tube of pipe leakage automatic safety device is provided with sealing cone, and valve body arranges at its corresponding position and valve body and connecting tube can be made like this to close tighter with the conical surface of its coupling.
Pipe leakage automatic safety device can promote return push rod and make valve body return after overload is eliminated, and pipeline is resumed work.
Pipe leakage automatic safety device structure is simple, security and stability is high, be swift in response.
