The upper surface of described sliding axle can be provided with a center pit.The upper surface of described sliding axle can be middle part inner concave shape structure.
Can be provided with O-ring seal on the filled inner orifice on described cavity top.With the sealing effectiveness between filled endoporus of further reinforcement and the bellows.
Can be provided with one to two O-ring seal between the middle-end of described sliding axle and the filled endoporus.
The diameter of described sliding axle can be less than the internal diameter that fills endoporus.Can be provided with the endoporus that is connected with joint in the described sliding axle.
Available screw thread or other connected modes are connected and fixed between described bellows seat and the cavity.
Also can be provided with spring between described cavity and the pedestal.
The utility model is reasonable in design, compact conformation, can finish the vacuumizing of bellows continuously, fill temperature sensing agent, with sealing steel ball or sealing to follow closely and operation such as seal, both omitted filled process duct, reduced solder joint, and make bellows in transportation, installation, use because of the gas filling technology pipe fractures, ftractures to cause and leak significantly reducing of possibility, guaranteed product quality.Simultaneously, also simplify production process, reduced production cost.The utility model is applicable to heating power expansion valve in the vapor compression refrigeration device, the particularly H type automobile air-conditioning heating power expansion valve manufacturing of bellows.
Description of drawings
Fig. 1 vacuumizes one-piece construction cut-open view under the state for the utility model at bellows;
Fig. 2 is that the utility model seals the structure cut-open view under the state after filling temperature sensing agent.
Among the figure: 1 is the bellows seat, and 2 is cavity, and 3,5 is O-ring seal, and 4 is sliding axle, and 6 is spring, and 7 is pedestal, and 8 is bellows, and 9 is the bellows circular hole, and 10 for sealing steel ball, and 11 is screw thread, and 12 is joint, and 13 is limited block, and 14 for filling endoporus.
Embodiment
The utility model mainly by the pedestal 7 of band sliding axle 4, places cavity 2 and bellows seat 1 on the pedestal 7, places the formations such as spring 6 between cavity 2 and the pedestal 7.Be provided with in the cavity 2 and fill endoporus 14 and limited block 13, be provided with the joint 12 that communicates with filled endoporus 14 outward, the filled endoporus on top is provided with O-ring seal 3 for 14 mouthfuls; The upper surface of sliding axle 4 is provided with a center pit, is used for placing sealing steel ball 10, can be provided with one to two O-ring seal 5 between middle part and the filled endoporus 14.Be connected and fixed with screw thread 11 or other modes between bellows seat and the cavity.
During use, bellows 8 places in the bellows seat 1, sealing steel ball 11 places in the center pit of sliding axle 4, by screw thread or other connected mode the O-ring seal 3 between bellows 8 and the cavity 2 is compressed, make between bellows 8 and the cavity 2 and reach sealing, O-ring seal 5 between sliding axle 4 and the cavity 2 can guarantee to reach sealing between sliding axle 4 and the cavity 2, because the effect of spring 6 and spacer pin 13, make sliding axle 4 be in bottom dead centre, seal between steel ball 11 and the bellows circular hole 9 certain distance is arranged, form an annular seal space between O-ring seal 3 and the O-ring seal 5, the sealing chamber is connected with the bellows chamber by the circular hole on the bellows, as shown in Figure 1.Joint 7 on the cavity 2 is connected by external pipeline, by-pass valve control and vacuum pump, after taking out air in above-mentioned two annular seal spaces that are connected to the greatest extent with vacuum pump, cut off the vacuum pump path, joint 7 is connected by external pipeline, by-pass valve control and temperature sensing agent steel cylinder, and temperature sensing agent is injected in above-mentioned two annular seal spaces that are connected.Because the sealing function of O-ring seal 3 and O-ring seal 5, outside air can not be bled in above-mentioned two chambeies, the temperature sensing agent that fills in latter two chamber of temperature sensing agent can not spill.By the electrode on the welding machine bellows seat 1 is moved down together with cavity 2, compression spring 6, compress with circular hole 9 on the bellows 8 to sealing steel ball 11, seal steel ball 11 after the energising with 9 welded closure of the circular hole on the bellows 8, temperature sensing agent is filled in the bellows chamber, finish filling of bellows temperature sensing agent, as shown in Figure 2.
