Abstract
The utility model relates to a magnetic fluid sealing safety valve whose core tube is sheathed in a magnetic conduction shell body, and the coil with a frame is inserted into the cavity formed by the core tube and the magnetic conduction shell body. The utility model is characterized in that a magnetic fluid is poured into the contact surface between a valve cover and the core pipe after passing through a leading tube, a dish-shaped cover and the valve cover upper leading hole, which forms an evenly distributed magnetic seal layer with a peculiar property. The utility model can be used in the fields of petroleum, chemical industry, machinery, instrument, environment protection, medical treatment, etc., having the advantages of adjustable magnetic force, easy control, high safety, good sealing, and long life time.
Description
The utility model relates to a kind of magnet fluid sealing safety valve, specifically a kind of magnet fluid sealing electromagnetic valve.
The present domestic pressurized container that has, pressurized protection equipment, 1,650,000 in boiler, and also annual requirement is again more than 500,000, and these equipment use Direct spring loaded safety valve usually.The long-term use of Direct spring loaded safety valve, can make its metallic element corrosion, spring fatigue, seal rubber pad is aging, the pressure control imbalance, dielectric leakage wastes energy, befouling environment, especially in petrochemical industry, use, the possibility of initiation fire blast is often arranged, can give national wealth, personal safety causes serious consequence.
The purpose of this utility model is to overcome deficiency in the prior art, and a kind of magnet fluid sealing safety valve is provided.
This magnet fluid sealing safety valve is by being fixed on linking every magnetic joint and equipment of magnetic core pipe lower end.The magnetic core pipe box is contained in the magnetic conduction casing, in the cavity of the two formation, insert the coil that has framework, annular gland is screwed into and is pressed on the framework of coil from the magnetic conduction casing top, valve gap is pressed on magnetic core pipe upper surface by the guiding resetting-mechanism, exhaust hood is installed on the magnetic conduction casing, it is characterized in that: the outside that is equivalent to magnetic core pipe surface of contact on the valve gap has the magnetic fluid introduction hole, and the dish-shaped cover that contains magnetic fluid introduction hole on the valve gap is fixed on the valve gap, and magnetic fluid ingress pipe and dish-shaped cover link.The guiding resetting-mechanism of valve gap is to pass by three groups to go up uniform hole valve gap garden week and be screwed into guide pillar on the magnetic conduction casing, is sleeved on the pressure spring on the guide pillar, and pressure is regulated, and nut forms.Replace this electromagnet safety valve with the permanent magnet safety valve.
This magnet fluid sealing relief valve design novelty, simple in structure, under the effect in magnetic field, the magnetic fluid that injects is adsorbed between valve gap and the magnetic core pipe surface of contact, forms the peculiar magnetic seal layer of performance that is evenly distributed, and the magnetic force of this valve is adjustable, be easy to control, safe and reliable, good seal, applied widely, long service life can be widely used in fields such as Petro-Chemical Machinery instrument environmental protection medical treatment.
Fig. 1 is the structural representation of magnet fluid sealing safety valve.
Now in conjunction with the accompanying drawings the utility model is done following explanation.
An end and the equipment 2 every magnetic joint 1 of magnet fluid sealing safety valve link, and the other end and magnetic core pipe 15 link, and are nonmagnetic material every magnetic joint 1.Magnetic core pipe 15 is sleeved in the magnetic conduction casing 3, and the coil 14 of packing in the cavity between the two and having framework 13, annular gland 11 are pressed on the framework 13 of coil 14, and valve gap 10 is pressed on the upper surface of magnetic core pipe 15 by the guiding resetting-mechanism.Valve gap guiding resetting-mechanism is to pass by three groups to go up uniform hole valve gap garden week and be screwed into guide pillar 5 on the magnetic conduction casing, be sleeved on the pressure spring 4 on the guide pillar 5, and pressure adjusting nut 6 is formed.Magnetic fluid is through magnetic fluid ingress pipe 9, and dish-shaped cover 8, the introduction hole of valve gap 10 are injected between the surface of contact of valve gap 10 and magnetic core pipe 15, forms the peculiar magnetic seal layer of performance.When valve internal pressure during greater than the magnetic force of solenoid valve, valve gap 10 is opened, and pressurized gas are discharged by exhaust hood 12, when valve internal pressure during less than solenoid valve magnetic force (also will consider to act on the pressure of the spring of valve gap 10 certainly), valve gap 10 is closed automatically, and magnetic fluid also replenishes automatically simultaneously.
