Abstract
The utility model relates to a closing device for a vacuum tube, particularly a device for sealing a heat pipe, comprising a screw rod, a hollow bolt, a sleeve tube, a joint, a one-way valve, a mouth piece, etc., wherein, one end of the sleeve tube is connected with the hollow bolt, while the other end is connected with the joint; the one-way valve is arranged in the joint; the vacuum tube is vacuated through the sleeve tube; the opening of the vacuum tube is sealed and welded by the joint and the one-way valve; consequently, the purpose of sealing the opening of the vacuum tube is realized. The utility model with the advantages of easy operation and high sealing reliability is detachable and repetitive.
Description
The utility model relates to the device that a kind of device, especially opposite heat tube that is used for that vacuum tube is sealed seals.
In the prior art, last procedure of making vacuum tube is vacuumizing and ferrule technology of the mouth of pipe, at present conquassation methods that adopt more, promptly at the mouth of pipe tubule of making by soft metals such as copper of burn-oning in advance, vacuumize the back on special equipment with mouth of pipe conquassation, thereby reach sealing purpose, but this method requires extremely tight to equipment and technical process, careless slightlyly promptly may cause sealing failure, produce phenomenons such as gas leakage, whole vacuum tube just can't use.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of simple, seal reliability height, the detachable and vacuum tube closing device that can use repeatedly.
The purpose of this utility model can realize by following measure: this vacuum tube closing device, contain screw rod (1), sleeve pipe (2), mouthpiece (3), sealing ring, hollow bolt (5), unidirectional valve (7), joint (8), it is characterized in that screw rod (1) is installed on the internal thread of sleeve pipe (2), on screw rod (1), be with sealing ring (4), hollow bolt (5) is enclosed within the end that sleeve pipe (2) was gone up and be connected to screw rod (1), be with sealing ring (10) on the unidirectional valve (7) and be installed in the joint (8) by screw thread, be with sealing ring (9) on the joint (8) and be installed in the other end of sleeve pipe (2), mouthpiece (3) is installed on sleeve pipe (2) by screw thread.
The purpose of this utility model also can realize by following measure: relative convex-concave (12,12 ') structure of coincideing is arranged respectively on screw rod (1) and the unidirectional valve (7), and the other end of screw rod (1) is equipped with handle (6); The available bolt of unidirectional valve (7) communicates at its double-screw bolt axial drilling and with radial bore and constitutes valve opening (14), and the sealing ring (10) that is with on the unidirectional valve (7) is made for softer metals.
Operation principle of the present utility model is: an end and vacuum tube (11) mouth of pipe of joint (8) are welded together, unidirectional valve (7) is installed in the joint (8) by the internal thread of joint (8), but do not screw, this moment, the valve opening (14) because of unidirectional valve (7) communicated, so the air of joint (8) both sides is negotiable by unidirectional valve (7), be with sealing ring (9) on the joint (8) and be installed in an end of sleeve pipe (2) by screw thread, to be with the hollow bolt (5) of screw rod (1) and the other end of sleeve pipe (2) screws by screw thread, at this moment junction block (3) is connected with vacuum pump and vacuumizes, the back adjusting screw(rod) (1) that is evacuated in the pipe is tightened in unidirectional valve (7) in the joint (8), avoid gas leakage, then sleeve pipe (2) and joint (8) are outwarded winding and taken off, in order to improve the reliability of sealing, with unidirectional valve (7) and the inboard soldering and sealing of joint (8), the vacuum tube mouth of pipe has just sealed like this.
The utility model has following advantage compared to existing technology:
1, the utility model is simple in structure, detachably also can use repeatedly, and is easy to operate;
2, because the utility model has been avoided the dissimilar metal welding between soft metal and the steel, guarantee the reliability of sealing and improved sealing-strength greatly, saved conquassation vacuum tube jaws equipment;
3, the utility model also can be cut also the mouth of pipe of sealing, and reseals, and can make vacuum tube regeneration, repacking like this, has reduced percent defective.
