Description
Technical field
The improvement that the utility model is related to a kind of pneumatic actuator is invented, more particularly to a kind of top dress bevel type gear is pneumatic
The improvement invention of diaphragm actuator.
Background technology
The hand gear of pneumatic diaphragn actuating mechanism mainly has two kinds of forms at present：Top dress handwheel, side dress handwheel（Middle part）,
Hand-automatic switching mode has shift type and without gear formula.Top dress handwheel is arranged on the top of thin-film heads, needs operator during action
Operated at the top of thin-film heads.The problem of top dress hand gear is present is that handwheel selection is larger higher, it is sometimes desirable to by
Ladder is operated, and operation moment of torsion is big, and operator is easily injured by pipeline heat radiation.Side fills handwheel（Middle part）Although
Height and mode of operation all become to be beneficial to operator, but side dress handwheel（Middle part）Occupy having between executing agency and valve
Space is limited, disturbs the effective action scope of locator, limit switch.Moreover side fills handwheel（Middle part）All it is shift type, structure
Complexity, due to often without using, gearshift part gets rusty, clamping stagnation all constrain hand gear it is emergent when using effect.And can
The normal use of executing agency can be directly affected, hand gear of dismantling of having in many cases.
Utility model content
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided a kind of safe operation can
The top dress bevel type gear pneumatic diaphragn actuating mechanism lean on, to occupy little space.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that to realize：This kind top dress umbrella
Type gear pneumatic diaphragm actuator, includes membrane cover, push rod, it is characterised in that：Guide sleeve is installed on the upper membrane cover,
Slided in guide sleeve and be provided with adapter sleeve, adapter sleeve lower end is fixedly connected with push rod, and connection set upper side is connected with screw rod, and screw rod can be even
Slided in female connector, connection set upper side is provided with the pressure cap that limitation screw rod departs from, and corresponding screw rod lower end is provided with what is matched with pressure cap
Limited step, the upper membrane cover upper end are provided with bevel type gear case, and bevel type gear case is connected with upper membrane cover by terminal pad, umbellate form tooth
Roller box side is provided with handwheel, and handwheel is connected by bevel type gear with screw drive.
The adapter sleeve, pressure cap, guide sleeve, screw rod use stainless steel.
The adapter sleeve is outer-hexagonal structure, and the guide sleeve is interior hexagonal structure.
The beneficial effects of the utility model are the top dress bevel type gear pneumatic diaphragn actuating mechanisms after improving, and are appointed using without gear
The top dress bevel type gear of meaning switching can effectively prevent the interference between hand gear and actuator regular event, and operation moment of torsion is small,
Side safe operation is reliable, simple in construction, occupies little space.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
The action schematic diagram of Fig. 2 the utility model opened manually actuators.
Fig. 3 actuators of the present utility model are in the action schematic diagram in home position.
Fig. 4 the utility model automatically controls the action schematic diagram of opening executer.
Fig. 5 is the structure chart that the utility model is applied to regulating valve.
Embodiment
Accompanying drawing illustrates structure of the present utility model, further illustrates it about details in conjunction with accompanying drawing below.The top fills
Bevel type gear pneumatic diaphragn actuating mechanism, include membrane cover 2, lower membrane cover, diaphragm, spring, push rod 9, pacify on the upper membrane cover 2
Slided equipped with guide sleeve 4, in guide sleeve 4 and be provided with adapter sleeve 1, the lower end of adapter sleeve 1 is fixedly connected with push rod 9, the connection of the upper end of adapter sleeve 1
There is screw rod 6, screw rod 6 can slide in adapter sleeve 1, and the upper end of adapter sleeve 1 is provided with the pressure cap 3 that limitation screw rod 6 departs from, corresponding screw rod
6 lower ends are provided with the limited step that matches with pressure cap 3, and the upper upper end of membrane cover 2 is provided with bevel type gear case 8, bevel type gear case 8 and
Upper membrane cover 2 is connected by terminal pad 5, and the side of bevel type gear case 8 is provided with handwheel 7, and handwheel 7 is driven by bevel type gear and screw rod 6
It is connected.
In the utility model, the adapter sleeve 1 is outer-hexagonal structure, is easy to lower end to be locked with push rod 9, upper end and guide sleeve
4 coordinate, and anti-throw-out lever 9 rotates in lifting process, and damage diaphragm, torsion thrum spring, influence the normal use of actuator, described to lead
It is interior hexagonal structure to set 4, the nitridation of materials'use stainless steel is corrosion-resistant, wear-resistant, is fixed on membrane cover 2, it is ensured that perform
Device is manual, auto state can provide reliable and stable anti-rotation and be oriented to.
Adapter sleeve 1, pressure cap 3, guide sleeve 4, screw rod 6 using stainless steel, will not all need because of getting rusty
In use, the phenomenon that can not be operated or damage.Connect under adapter sleeve 1 push rod 9, on connect screw rod 6, led outside in guide sleeve 4, completely one
Body, it is efficient, practical, simple and direct to realize manually-automatic function.Adapter sleeve 1 coordinates with guide sleeve 4 realizes-automatic manually
What state, push rod 9 is all without rotation and swings.The screw rod 6 of kink connection arbitrarily slides in adapter sleeve 1, even if rotating
Also adapter sleeve 1 will not be driven, and with turn, manually-auto state switches without shifting gears, and realizes that undisturbed arbitrarily operates.Bevel type gear
Drive screw 6 is lifted, and screw rod 6 drives adapter sleeve 1 to be slided in guide sleeve 4 and risen so that push rod 9 rises；When the backspin of screw rod 6,
Push rod 9 moves down therewith under the action of the spring, so as to fully achieve manually operated switch and optional position control.At screw rod 6
In original position（Lower end）, screw rod 6 is promoted to top.Executing agency's push rod 9 exists with the upper and lower lifting of air pressure change, adapter sleeve 1
Upper and lower slip in guide sleeve 4, now, screw rod 6 and the inner cylinder of adapter sleeve 1 are connectionless, all the time in motionless state.Bevel type gear is
Efficient manual driving device, bevel type gear improve drive efficiency.The side of handwheel 7 operation of bevel type gear, reduces operation
Height and difficulty, avoid operator and personal injury caused by pipe-line equipment close contact possibility.
In summary, preferred embodiment of the present utility model is these are only, is not intended to limit of the present utility model
Protection domain.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc., all should be wrapped
It is contained within the scope of protection of the utility model.
