And, valve seat member with the valve opening on the opening portion that is fixed by welding in valve body has discoid shape, be formed with the scolder chute on its peripheral wall surfaces, be fixed on the sidewall of valve body portion and the pipeline on the valve seat member, on wall portion, be formed with the upwards outstanding indenture (デ イ Application プ Le) in footpath corresponding to fixing part.
Description of drawings
Fig. 1 is the sectional view of mortor operated valve of the present invention.
Embodiment
Fig. 1 is the sectional view of mortor operated valve of the present invention that has unloaded the state of stator module.
Mortor operated valve 1 has the valve stem 20 with the path of the valve body portion 10 of the made one-tenth of methods such as punch process usefulness tubulose and formation coaxial with it.Opening end in valve body portion is pressed into valve seat member 30, fixes with engagement means such as welding.
Form clack box 12 in the inside of valve body portion 10, valve opening 31 is set at the central part of valve seat member 30.
Valve seat member 30 is a disc-shaped component, is positioned the opening end of valve body portion 10 by flange part 32.Formed groove 36 on the sidewall of valve seat member 30, scolder flows into groove 36 and has strengthened weld strength during welding seat member 30 in valve body portion 10.
On the end face of clack box 12 sides of valve seat member 30, stepped part 34 is set.The apical position of pipeline 40 insert the pipeline 40 that the gateway fixing refrigeration agent is used, but stepped part 34 has been limited in side in valve body portion 10.On pipeline 40 and position that the sidewall of valve body portion 10 connects, be provided with indenture 42a with this make engage reliable.
On another pipeline 42 that engages with valve seat member 30, also formed indenture 42a.
Valve body portion 10 links into an integrated entity with the valve stem 20 of path by stepped part 14, par 16.
Opening portion as the shell 50 of pressurized container is connected on the stepped part 14 of valve body portion 10, is fixedly mounting with the welding means.
On the opening end of valve stem 20, install and fix spiral component 80.Fixedly spiral component 80 has female thread portion 82.
Disposing rotor component 60 in the inboard of shell 50, it is turned round driving according to the excitation signal of not shown valve stem.Rotor component 60 links into an integrated entity by connector element 66 and screw axis 70.
Screw axis 70 has outer screw section 72, screws togather with the female thread portion 82 of spiral component 80.On the end of its clack box 12 sides, have the screw axis 70 of the flange part 75 in big footpath, in the inside diameter of valve stem 20, be directed sliding freely.
In the position of the flange part 75 of adjacency screw axis 70, be provided with slot part 74 and be fixed with the valve retainer 90 of tubulose.The outer diameter part of valve retainer 90 is being directed in the inside diameter of valve stem 20 sliding freely.Valve body 100 is supported by supporting member 102 in the end of valve seat member 30 sides of valve retainer 90.
Ball 110 is inserted in underpart at valve retainer 90, and spring 112 is configured between ball 110 and the screw axis 70.This spring 112 produces spring force in the direction of valve body 100 being pressed to valve seat member 30 thrusters by ball 110.
In the outside of valve stem 20, setting-in be used for the fixed side helical member 130 of rotating amount of restrict rotor member 60.On the upper end side of this fixed side helical member 130 and lower end side curved part 134,132 is set, the curved part 132 of lower end side inserts 18 li in the hole that is fixed on the par 16 that is arranged at valve body portion 10.
The mobile side helical member 140 that screws togather with this fixed side helical member 130 has protruding terminus 142, and protruding terminus 142 engages with the teat 62 that the axle direction along rotor of the inside diameter that is arranged on rotor component 60 extends.
If rotation drives rotor component 60, screw axis 70 is transmitted on axle direction by fixing spiral component 80.
Be accompanied by moving on the axle direction of this screw axis 70, rotor component 60 also moves up and down while rotating.Mobile side helical member 140 rotates together along with rotor component 60 and is guided by fixed side helical member 130.
By the rotation number of suitable setting fixed side helical member 130, the rotating amount of restrict rotor member 60 that can be suitable.
Moving up and down by valve retainer 90 of screw axis 70 is communicated to valve body 100.Valve body 100 corresponding to the rotating amount of rotor component 60 with respect to 31 clutches of valve opening, the control refrigeration agent pass through flow.
Mortor operated valve of the present invention as mentioned above, form valve stem that the valve body portion of clack box and guiding sliding freely be used for supporting the valve retainer of valve body and fixing spiral component has been installed with single member formation, therefore, can cut down number of parts, seek the simplification of all structures of mortor operated valve, and improved alignment, also improved the coaxality of valve body and valve opening.The slynessization so the opening and closing operations of valve also becomes.
