Abstract
The utility model provides the safety control valve of polyethylene equipment, which belongs to the field of control valves and comprises a valve body, a valve rod, an air cylinder and a cylinder shaft. The lower end of the valve rod is penetrated into the valve body and is connected with a ball valve switch. The upper end of the valve rod is connected with the cylinder shaft of the air cylinder through connecting pieces and single-row radial ball bearings. A connecting frame is arranged between the air cylinder and the valve body. The top of the air cylinder is covered with a cap-shaped magnetic locker and is matched with the connecting frame. The cap-shaped magnetic locker is covered with a magnetic lock opener matched therewith. The safety control valve of the polyethylene equipment is reasonable in design, wherein during operation, the cylinder shaft and the valve rod are consistent in concentricity and the occurrence of a radial deflecting force moment is avoided. Therefore, the running safety of equipment is improved. Meanwhile, the fault-free operation time and the service life of equipment are also prolonged. The safety control valve is additionally provided with the magnetic locker, thus can be operated manually or automatically. In this way, the safety control valve can be adjusted according to the running state of the equipment without the need of any extra manual valve, thereby facilitating the operation. The defect that the manual operation is disabled during the breakdown of an automatic control valve is also avoided.
Description
Technical field
The utility model belongs to valve, particularly relates to a kind of polyethylene device safety control valve.
Background technique
Valve has a wide range of applications in industries such as water supply, air feed, oil, chemical industry, pipeline transport along with the generation of fluid circuit produces.Safety valve is a kind of safety protection valve, and its keying is controlled by external force.Safety valve is divided into two kinds of manually operated valve and self-acting valves usually, self-acting valve do not need to refer to external force to drive, but the energy that relies on medium self makes the valve of valve event, the actuator of autocontrol valve has pneumatic and electronic two kinds, locate by support between actuator and the valve body, cylinder axis and valve rod use the double end coupling to transmit moment of torsion, owing to adopt the bolt location between support and actuator and the valve, valve packing also is to be made by softer materials such as graphite, tetrafluoros, can not bear radial impact load.Problems such as filler leakage particularly often appear in polyethylene device, for switch valve frequently, this problem is especially serious, loss and waste have been caused, autocontrol valve breaks down easily simultaneously, when autocontrol valve breaks down, can not carry out manual operation again, bring certain drawback to production.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of polyethylene device safety control valve is provided.
Polyethylene device safety control valve of the present utility model, be to be constituted by valve body, valve rod, cylinder and cylinder axis, the lower end of valve rod pierces into that valve body is connected with the ball valve switch, the upper end is connected with the cylinder axis of cylinder with single-row radial ball bearing by link, be provided with link press span between cylinder and valve body, link and single-row radial ball bearing seat are on connecting rod; The top of cylinder is covered with hat magnetic lock and cooperates with link press span, is covered with the magnetic lockaid gun on the hat magnetic lock and matches with it.
As further improvement of the utility model, the inwall that between hat magnetic lock and cylinder, is provided with spring, hat magnetic lock be provided with link press span on recess and groove the elasticity magnetic post and the lock pin that match respectively.
As further improvement of the utility model, be provided with the magnetic patch corresponding with elasticity magnetic post on the hat magnetic lock at the inwall of magnetic lockaid gun.
Polyethylene device safety control valve of the present utility model, reasonable in design, make cylinder axis when working, consistent concentricity be arranged with valve rod, avoid producing a radial deflection moment, improve the Security of equipment operation, prolonged valve Mean time to failure and working life; Down, the impact force that valve rod is subjected to is born by the bearing of setting up, and has guaranteed concentricity, can make the medium polyethylene powders of conveying that problems such as leakage not take place under the operating mode condition of severe, and valve switch is smooth and easy in working order, steadily; Set up the magnetic force lock, but make the utility model automatic/hand dual-purpose, at any time according to the equipment state adjustment, need not establish manually-operated gate, easy-to-operat in addition.When having avoided autocontrol valve to break down, can not carry out the drawback of manual operation again.
