Abstract

The utility model discloses a vacuum superconductive radiator sealing valve, belongs to the technical field of sealing devices, particularly relates to a sealing device for a vacuum superconductive radiator, and aims to solve the technical problem of providing the sealing device for the vacuum superconductive radiator, wherein the sealing device can ensure the sealing effect and meanwhile is convenient to operate and reusable. The technical scheme is that the sealing device for the vacuum superconductive comprises a valve body, a ball body and an inner support screw, wherein a through hole with a step is formed inside the valve body. A small-diameter section in the through hole is a first valve hole, and a large-diameter section in the through hole is a second valve hole. The conical transition is formed between the first valve hole and the second valve hole. The ball body is placed in the second valve hole, and the diameter of the ball body is larger than that of the first valve hole. The inner support screw is sleeved inside the second valve hole through screw threads. The sealing device is applied to the vacuum superconductive radiator.

Description

A kind of vacuum superconductive radiator seal valve
Technical field
A kind of vacuum superconductive radiator seal valve of the utility model belongs to the seal arrangement technical field, specially refers to a kind of seal arrangement of vacuum superconductive radiator.
Background technique
Vacuum superconductive radiator is a kind of novel household heating installation in the market, after needing in the vacuum superconductive radiator manufacture process radiator injected superconducting liquid, vacuumizes, then sealing.What vacuumize at present mouthful is a thin metal pipe that is welded on radiator one end, exhausts after the vacuum its flattening, is welded, and can not reuse.Vacuum superconductive radiator need to be annotated superconducting liquid when maybe needing to vacuumize, and thin metal pipe need to be cut off, and carries out further work again, and is very inconvenient.Each " locked in " operation all needs to be swift in motion, and prevents that air from entering, and operator's technical requirements and qualification are had relatively high expectations.
The model utility content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is to provide a kind of easy to operate, reusable seal arrangement when guaranteeing sealing effect for vacuum superconductive radiator.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of vacuum superconductive radiator seal valve, comprise valve body, spheroid and interior top screw, described valve inner has the through hole with step, little one section of diameter is the first valve opening in the described through hole, one section that diameter is large is the second valve opening, be the circular cone transition between the first valve opening and the second valve opening, described spheroid is arranged in the diameter of the second valve opening and spheroid greater than the diameter of the first valve opening, and described interior top screw is inner at the second valve opening by thread set.
The end that described valve body has the second valve opening is provided with outside thread and has been threaded connection bonnet.
Be provided with pad between described bonnet and the valve body.
The material of described spheroid is silica gel, or is rubber.
The utility model is compared with existing technology the beneficial effect that has: by open the through hole of step at valve inner, be designed to the circular cone transition between large the second valve opening of the first valve opening that through-hole diameter is little and through-hole diameter, spheroid is withstood on the tapered segment of transition between the first valve opening and the second valve opening, again that interior top screw is inner at the second valve opening by thread set;
Before sealing during to the vacuum superconductive radiator extracting vacuum, bleeding point with the first valve opening vacuum superconductive radiator connects first, spheroid is put into valve body, again the second valve opening is connected with the vacuum pump valve, thereby in whole extracting vacuum process, valve inner is state of isolation with the external world, the complete rear spheroid of extracting vacuum is on the tapered segment that automatically withstands on transition between the first valve opening and the second valve opening under the effect of pressure difference, thereby with the sealing of the first valve opening place, be screwed into interior top screw this moment, makes a side of the tight spheroid of interior top screw one side pressure, further enhanced leaktightness effect, this sealing means sealing effect can guarantee, and is easy to operate, and can reuse, in the time of need to opening sealing, the interior top screw of back-outing takes out spheroid and gets final product, and reseals next time and puts into new spheroid again.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is scheme of installation of the present utility model;
Among the figure, 1 is the first valve opening, and 2 is valve body, and 3 is spheroid, and 4 is interior top screw, and 5 is the second valve opening, and 6 is pad, and 7 is bonnet, and 8 is the heating tube water intake, and 9 is heating pipe, and 10 is heat dissipation column, and 11 is empty superconducting radiator.
Embodiment
As shown in Figure 1 and Figure 2, a kind of vacuum superconductive radiator seal valve, comprise valve body 2, spheroid 3 and interior top screw 4, described valve body 2 inside have the through hole with step, little one section of diameter is the first valve opening 1 in the described through hole, and one section that diameter is large is to be the circular cone transition between the second valve opening 5, the first valve openings 1 and the second valve opening 5, described spheroid 3 is arranged in the diameter of the second valve opening 5 and spheroid 3 greater than the diameter of the first valve opening 1, described interior top screw 4 by thread set in the second valve opening 5 inside.
The end that described valve body 2 has the second valve opening 5 is provided with outside thread and has been threaded connection bonnet 7.
Be provided with pad 6 between described bonnet 7 and the valve body 2.
The material of described spheroid 3 is silica gel, or is rubber.
When injecting superconductive liquid to vacuum superconductive radiator 11, do not put spheroid 3 first, after the filling, again spheroid 3 is put into valve body 2.When maintenance needs the filling superconductive liquid, back out interior top screw 4, take out spheroid 3, when vacuumizing, put into again new spheroid 3.
Working procedure of the present utility model is: an end that first valve body 2 is had the first valve opening 1 is fixedly connected with the bleeding point of vacuum superconductive radiator 11, spheroid 3 is put into valve body 2, then an end that valve body 2 is had the second valve opening 5 is connected with the vacuum pump valve, to vacuum superconductive radiator 11 extracting vacuum, after extracting vacuum is finished, unload vacuum pump, at this moment spheroid 3 is automatically with 1 sealing of the first valve opening, then interior top screw 4 is screwed into, makes a side of the tight spheroid 3 of interior top screw 4 one side pressures, the bonnet 7 of screwing at last.
At this moment, vacuum superconductive radiator 11 can be started working, and outside hot water enters from heating tube water intake 8, and heat is delivered to superconductive liquid in the heating pipe 9 by heating pipe 9, and then superconductive liquid is dispelled the heat by heat dissipation column 10.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.For example, the transition portion of the first valve opening 1 in the utility model and the second valve opening 5 is designed to wedge shape etc. other can realize any shape of its function.
