Abstract
A valve seat supporting rod assembly of an electronic expansion valve comprises a hollow valve seat and a supporting rod with an external thread, wherein a joint pipe is welded on the lower end of the valve seat; and the supporting rod is inset and injecting molded on the valve seat via a boss on the upper end of the valve seat. Because the supporting rod is embedded and injecting-molded on one end of the valve seat, the welded valve seat and the joint pipe are placed in a die for injection molding and then the supporting rod and external thread on the supporting rod are made; and large batch production can be realized, so that work efficiency of valve seat supporting rod assembly is greatly improved. Produced large batch assemblies possess uniform precision; and then the assemblies are installed on the electronic expansion valve, so the controlling precision of expansion valve is also improved.
Description
[technical field]
The utility model relates to a kind of valve, refers in particular to the electric expansion valve of the flow of controlling fluid.
[background technique]
At present, electric expansion valve has been widely applied in the reducing pressure by regulating flow and Flow-rate adjustment of fluid, it is to utilize to be conditioned the parameter generating signal, according to the computer setting program, control the voltage or the electric current that put on coil, the magnet rotor that drives main valve body rotates, thereby control moving up and down of needle and realize changing the circulation area of valve port, reach the purpose that flow is regulated automatically, for this reason, connected the strut that is threaded with the magnet rotor of main valve body on valve seat.
Present stage, valve seat and strut independently process respectively separately, and then couple together by welding manner and become valve seat strut assembly, because electric expansion valve is more accurate valve, higher to the requirement of welding procedure like this, during welding, manufacturing efficiency is low, causes cost of production high; And the Product Precision conformity of the valve seat strut assembly that in batches welds out is poor, and the precision of the electric expansion valve of assembling out with them is also lower.
[model utility content]
The purpose of this utility model is to be to overcome the deficiencies in the prior art, and the valve seat strut assembly that a kind of technique is simple, the precision conformity is high, also can enhance productivity is provided, and it has improved the precision of electric expansion valve.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of valve seat strut assembly, it includes the valve seat of hollow and is with externally threaded strut, is welded with adapter in described valve seat lower end; The boss embedding and injection molding of described strut by the valve seat upper end is on valve seat.
In the improvement project to above-mentioned valve seat strut assembly, be provided with blind slot on the corresponding valve seat outer wall of the mosaic site of described valve seat and strut, be provided with in described blind slot with this mosaic site becomes one and consolidate salient point.
Compared with prior art, the beneficial effects of the utility model are: because it is that the strut embedding and injection molding is molded on valve seat one end, so just can be with the valve seat that welds together and take over and put into molding and forming in mould and go out outside thread on strut and strut, so just can realize large batch of production, thereby greatly improved the manufacturing efficiency of valve seat strut assembly, at this moment the batch production precision conformity of assembly out is high, has also just improved the control accuracy of expansion valve after then it being assembled into electric expansion valve.
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
[description of drawings]
Fig. 1 is the utility model embodiment's schematic perspective view;
Fig. 2 is the utility model embodiment's explosive view one;
Fig. 3 is the utility model embodiment's explosive view two;
Fig. 4 is the utility model embodiment's structural representation.
[embodiment]
The utility model is a kind of valve seat strut assembly, as shown in Figures 1 to 4, includes the valve seat 1 of hollow and with the strut 2 of outside thread 21, is welded with in described valve seat 1 lower end and takes over 3; Boss 11 embedding and injection moldings of described strut 2 by valve seat 1 upper end are on valve seat 1.The utility model is molded over strut 2 embedding and injection moldings on valve seat 1 one ends, so just can and take over 3 and put into molding and forming in mould and go out outside thread 21 on strut 2 and strut 2 valve seat 1 that welds together, so just can realize large batch of production, thereby greatly improved the manufacturing efficiency of valve seat strut assembly, at this moment the batch production precision conformity of assembly out is high, has also just improved the control accuracy of expansion valve after then it being assembled into electric expansion valve.
In the present embodiment, as shown in Fig. 2,4, be provided with blind slot 12 on corresponding valve seat 1 outer wall of the mosaic site 22 of described valve seat 1 and strut 2, be provided with in described blind slot 12 with this mosaic site 22 becomes one and consolidate salient point 23, can further get valve seat 1 and strut 2 embedding and injection moldings more firm like this.
Although describe the utility model in detail with reference to top embodiment, but it will be apparent to one skilled in the art that by the disclosure, and in the situation that do not break away from principle of the present utility model and the spiritual scope that described claim limits, can make a variety of changes or revise the utility model.Therefore, disclosure embodiment's detailed description only is used for explaining, rather than is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
Claims (2)
1. a valve seat strut assembly, is characterized in that, includes the valve seat of hollow and be with externally threaded strut, is welded with adapter in described valve seat lower end; The boss embedding and injection molding of described strut by the valve seat upper end is on valve seat.
2. valve seat strut assembly according to claim 1, is characterized in that, is provided with blind slot on the corresponding valve seat outer wall of the mosaic site of described valve seat and strut, is provided with this mosaic site becomes one to consolidate salient point in described blind slot.
