Abstract
The utility model discloses a novel pilot valve base which comprises a valve base body arranged in a pilot valve body, wherein a closed-loop step is arranged at the joint of the upper end surface and the side wall of the valve base body, and the closed-loop step and the pilot valve body are matched to form a welding groove for placing a welding ring. The novel pilot valve base is simple in structure and convenient for manufacture, and can change manual wire feed welding into automatic wire feed welding in the welding process of the pilot valve base and a capillary pipe, so that the stable welding quality is guaranteed and the purposes of reducing labors and improving efficiency are achieved.
Description
Technical field
The utility model relates to valve member, particularly a kind of novel guide's valve seat.
Background technique
Existing electromagnetism four-way change-over valve is the important devices of heat pump type air conditioner, is applicable to central authorities, split, window air conditioner etc.The action of existing electromagnetism four-way change-over valve is under the height pressure reduction pilot valve drive formerly that utilizes in the system, thereby realizes that conversion realizes the conversion of the refrigerant flow direction.Solenoid operated four-way valve selector valve pilot valve comprises component such as conduit, guide's valve body, ESCD capillary tube, attractor parts, core iron parts and guide's valve seat.Three welding holes that cooperate welding with capillary tube are arranged on the face of weld of existing electromagnetism four-way change-over valve guide valve seat; This welding hole end face outer side surface is the face of weld that cooperates with guide's valve body; Pilot valve capillary tube and valve seat welding procedure are: after suppressing capillary tube and guide's valve seat on the pilot valve body, by the manual wire feeding mode of full-time welder.Low, the required personnel of efficient reach welding quality more and influenced greatly by welder's technical ability like this, and it is inhomogeneous and silk feeding quantity is not enough to occur wire feed easily, and it is bad to cause welding disconnected weldering, if the wire feed positional deviation can cause outer fluid welding bad.
Summary of the invention
The utility model problem to be solved just provides a kind of novel guide's valve seat, and is simple in structure, easily manufactured, can realize that the welding of guide's valve seat and capillary tube changes the automatic feeding welding into by manual wire feed welding, guarantees that welding quality is stable, realizes cutting payroll to improve efficiency.
In order to solve the problems of the technologies described above; The utility model adopts following technological scheme: novel guide's valve seat; Comprise the valve seat body that is located in guide's valve body; It is characterized in that: the upper-end surface of said valve seat body and the joint of sidewall are provided with the closed loop step, and said closed loop step cooperates the welding groove that forms the placement weld-ring with guide's valve body.Form the welding groove, what make scolder flows, fills more abundant, and the product welding is fuller.
Further, said closed loop step is an annulus.Preferred structure, easy to process, stable welding.
Further, said closed loop step is a rectangular ring.
Further, said closed loop step comprises the axial vane surface of parallel valve seat body axis and the sagittal plane of vertical valve seat body axis.Be easy to machining.
Further, right angle transition between said axial vane surface and the sagittal plane.The processing most convenient.
Further, arc transition between said axial vane surface and the sagittal plane.Increase the area of contact of scolder and valve seat body, what make scolder flows, fills more abundant, and product welds fuller.
Further, chamfering transition between said axial vane surface and the sagittal plane.Increase the area of contact of scolder and valve seat body, what make scolder flows, fills more abundant, and product welds fuller.
Further, said chamfering is 45 degree chamferings.
After adopting technique scheme, the utlity model has following advantage: formerly on guide valve seat and the face of weld that guide's valve body cooperates a closed loop step is set, the raw material consumption through minimizing guide valve seat has reduced manufacture cost; The closed loop step cooperates with guide's valve body and forms the welding groove, through placing weld-ring at the welding groove, cancels artificial manual wire feed, realizes cutting payroll to improve efficiency, guarantee simultaneously scolder molten fully with welding groove in, avoid outer fluid welding bad.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is the schematic representation of first kind of transition structure between axial vane surface and the sagittal plane on the closed loop step;
Fig. 3 is the schematic representation of second kind of transition structure between axial vane surface and the sagittal plane on the closed loop step;
Fig. 4 is the schematic representation of the third transition structure between axial vane surface and the sagittal plane on the closed loop step.
Embodiment
A kind of embodiment of the utility model as illustrated in fig. 1 and 2; Novel guide's valve seat; Comprise the valve seat body 1 that is located in guide's valve body, be provided with closed loop step 2 in the upper-end surface of valve seat body and the joint of sidewall, said closed loop step cooperates the welding groove that forms the placement weld-ring with guide's valve body.In the present embodiment, the closed loop step is set to annulus.And said closed loop step comprises the axial vane surface 21 of parallel valve seat body axis and the sagittal plane 22 of vertical valve seat body axis.Here, right angle transition between said axial vane surface and the sagittal plane.
As shown in Figure 3, also can adopt the structure of arc transition between said axial vane surface and the sagittal plane.Or as shown in Figure 4, adopt the chamfering transitional structure between said axial vane surface and the sagittal plane.
In the foregoing description, the closed loop step also can be arranged to rectangular ring as required.
The utility model has realized that direct heating automatic feeding welds, and need not the manual wire feed of welder, realizes the personnel reduction and enlargement purpose; The closed loop step is set, has reduced guide's valve seat manufactured materials, thereby reduced cost; The slugging mode lets scolder be dissolved in fully in the welding groove, does not have outer fluid welding, and scolder is more evenly full, and weld strength is reliable.
Except that above-mentioned preferred embodiment; The utility model also has other mode of execution; Those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from the spirit of the utility model, all should belong to the defined scope of the utility model accompanying claims.
