Row device.
The purpose of this utility model is reached by following technical measures：
A kind of safety-type angled seat valve actuator, including the actuator being connected with angle pedestal valve, the top connection of the actuator
There is top cover, safety valve is connected with the top cover, the inner chamber of the safety valve and top cover and actuator communicates setting, the top
A transparent cap is provided with the cavity of lid to separate the cavity of actuator and safety valve.
As a further improvement, the end portion structure of the top cover is extended in the cavity of actuator, and and actuator
Cavity inner wall connection.
As a further improvement, the top cover is ladder pass, upside cavity is adapted with the transparent cap, lower side chamber
The indicating arm of body and actuator is adapted.
As a further improvement, offering an annular groove on the upside internal perisporium of the top cover, and it is provided with a spring catch
The fixed transparent cap of circle.
As a further improvement, the lower end periphery wall of the transparent cap is radially recessed a cascaded surface and is arranged with
One sealing ring, the cavity inner wall of the sealing ring and top cover are in sealing contact.
As a further improvement, the bottom centre of the transparent cap is provided with a blind hole upwardly extended, the blind hole it is interior
Footpath is identical with the internal diameter of cavity on the downside of the top cover.
As a further improvement, the actuator is to be threadedly coupled with top cover and top cover with the connected mode of safety valve.
By adopting the above-described technical solution, compared with prior art, the utility model has the advantages that：A kind of safety-type angle
Seat valve actuator, O-ring seal is combined with PC transparent caps, reaches enough sealings；Utilize stainless steel hole spring catch
Circle be pressed into stainless steel top cover, avoid because the hypertonia in actuator cause transparent cap to burst the problem of；Top cover uses
Transparent PC materials can realize the visualization for performing bar, the convenient state observed valve body and be turned on and off；On the top of actuator
Portion also sets up a safety valve, if the hypertonia in performing causes check ring to fail, therefore safety valve can be according to setting
Pressure value carries out safety exhaust.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Embodiment
Embodiment：As shown in Figure 1, Figure 2, Figure 3 shows, a kind of safety-type angled seat valve actuator, including what is be connected with angle pedestal valve are held
Row device 7, the top of the actuator 7 have been connected through a screw thread a top cover 5, and the part-structure of the lower end of top cover 5 extends to execution
In the cavity of device 7, the middle part of the top cover 5 forms a cavity, the upper end of the indicating arm 6 set in the cavity of actuator 7
Part-structure is located in the cavity of end cap 5, and the portion perimeter wall external diameter at the middle part of top cover 5 is more than opening for the top of actuator 7
Intraoral footpath, the portion perimeter wall contact with the open upper end face of the actuator 7；The cavity of the top cover 5 is stepped knot
Structure, upside cavity internal diameter are more than the internal diameter of downside cavity, set one mutually to be fitted with the upside cavity of top cover 5 in the upside cavity
The transparent cap 3 answered, it is described that an annular groove 501 is opened up on the internal perisporium of the upside cavity of top cover 5, and a spring catch is set
Circle 2 is connected in groove 501, and the check ring 2 contacts with the upper surface of the transparent cap 3, to fix transparent cap 3,
The lower end periphery wall of the transparent cap 3 is radially recessed a cascaded surface, and an O-shaped sealing is arranged with the cascaded surface
Circle 4, the cavity inner wall of the sealing ring 4 and top cover 5 is in sealing contact, to prevent the air pressure in normal range (NR) from being unlikely to from execution
Leaked out in device；, with the blind hole of uniform internal diameter, work as angled seat formed with one and the downside cavity of top cover 5 in the middle part of the transparent cap 3
When valve is opening, the indicating arm 6 in the cavity of actuator 7 can be along the cavity in the cavity in top cover 5 and transparent cap 3
Axially move；The upper end of the top cover 5 has also been connected through a screw thread a safety valve 1, and the safety valve 1 is of the prior art
Standard component, coordinate air pressure too high in excretion actuator 7 in time with top cover 5.
Operation principle：According to a kind of safety-type angled seat valve actuator described in embodiment, in normal operation
Actuator 7：For unlatching working condition when, the indicating arm in actuator 7 can move axially to transparent along the cavity in top cover 5
Cavity in top cover 3, then be located at by external observation to indicating arm 6 in the cavity of transparent cap 3, you can distinguish that angle pedestal valve is in
The state of unlatching；On the contrary, when actuator 7 is the working condition closed, indicating arm 6 moves down vertically, passes through external observation to finger
Show that bar 6 is not in the cavity of transparent cap 3, you can distinguish that angle pedestal valve is in the state closed.
When the pressure of the cavity of actuator 7 is more than the pretightning force of check ring 2, the pretightning force of check ring 2 will be overcome,
The top of transparent cap 3 is opened, excessive compressed gas can be pacified in gap overflow to the safety valve 1 of the periphery wall of transparent cap 3
When the pressure set points of full valve 1 are less than the pressure in actuator 7, excessive pressure can be excreted out automatically, to complete pressure release
Process.
