Abstract
The utility model is a pneumatic two-position cut-off valve which comprises a valve body part and an executing mechanism; wherein, the executing mechanism is divided into an upper executing device and a lower executing mechanism which are separated independently and are connected with each other; the bracket of the lower executing mechanism is fixedly connected with the valve base of the valve body part. Because the pneumatic piston two-position cut-off valve and the lower executing mechanism pneumatic diaphragm two-position cut-off valve have the same specification and the same design, when the cut-off valves with different types are exchanged, the upper executing mechanism of the pneumatic piston two-position cut-off valve is disassembled from the lower executing mechanism and is replaced with the upper executing mechanism of the pneumatic diaphragm two-position cut-off valve, or the upper executing mechanism of the pneumatic diaphragm two-position cut-off valve is disassembled from the lower executing mechanism and is replaced with the upper executing mechanism of the pneumatic piston two-position cut-off valve. The pneumatic two-position cut-off valve has the advantages of simple and convenient assembly and disassembly, rapid type exchange and strong generality; meanwhile, the replacement or maintenance of the parts in the executing mechanism is very convenient.
Description
[technical field]
The utility model relates to air control unit commonly used in a kind of industrial production, refers in particular to the Pneumatic two-position cut-off valve.
[background technique]
The Pneumatic two-position cut-off valve is as one of element commonly used in the industrial processes, and it mainly includes actuator, valve body parts two partly.At present according to actuator be piston type or diaphragm type and the Pneumatic two-position cut-off valve is divided into two cut-off valves of pneumatic piston and two kinds of models of two cut-off valves of air bladder, but the actuator of these two kinds of models separately designs support, and be a part that is connected with valve body parts as the support of actuator's part itself, when (being diaphragm type or diaphragm type become piston type) if the model of cut-off valve is exchanged as piston-type variable in present stage, will be from removal bracket, and being connected between the valve rod of the push rod that will separate actuator and valve body parts, just can pull down actuator at last, so the dismounting when carrying out the model replacing of current Pneumatic two-position cut-off valve is loaded down with trivial details, assembling is complicated, bring its versatility relatively poor, when maintenance, also bother, so be necessary fully current Pneumatic two-position cut-off valve is improved.
[model utility content]
The purpose of this utility model is to be to overcome the deficiencies in the prior art, and the Pneumatic two-position cut-off valve that a kind of dismounting is simple and convenient, easy to maintenance, model is exchanged quick and highly versatile is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of Pneumatic two-position cut-off valve includes valve body parts and actuator, it is characterized in that: described actuator is divided into top actuator and bottom actuator separately independent and that couple together; The support of described bottom actuator is fixedlyed connected with the valve block of valve body parts.
Aforesaid Pneumatic two-position cut-off valve is characterized in that: described top actuator includes cylinder and is arranged on piston in this cylinder; Between described cylinder and this support is to be threaded.
Aforesaid Pneumatic two-position cut-off valve is characterized in that: described top actuator includes down membrane cover, go up membrane cover and be clipped in diaphragm between them; Adopt between described down membrane cover and this support and be threaded.
Compared with prior art, the beneficial effects of the utility model: since with actuator be divided into be connected on, following two-part actuator, its lower middle portion actuator is connected with valve body parts, and it is two cut-off valves of pneumatic piston of same specification are identical with the bottom actuator design of two cut-off valves of air bladder, like this when carrying out the model exchange, as long as change the top actuator of two cut-off valves of air bladder after the top actuator of two cut-off valves of pneumatic piston and its underpart actuator taken apart into, or the top actuator that changes two cut-off valves of pneumatic piston after the top actuator of two cut-off valves of air bladder and its underpart actuator taken apart into gets final product, so dismounting of the present utility model is simple and convenient, model is exchanged quick, brings its versatility stronger; Simultaneously, change or maintenance actuator in part the time also very convenient.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

[embodiment]
The utility model is a kind of Pneumatic two-position cut-off valve, it includes valve body parts 1 and actuator 2, wherein valve body parts 1 includes valve block 11 and valve rod 12, in the utility model, actuator 2 is divided into top actuator 21 and bottom actuator 22 separately independent and that couple together; As shown in Figure 3, bottom actuator 22 includes support 221, pressure spring 222, push rod 223 and pallet 224, the valve rod 12 of valve body parts 1 is connected with the push rod 223 of bottom actuator 22, and support 221 is fixedlyed connected with the valve block 11 of valve body parts 1, adopts bolt 3 to connect usually.
Embodiment one shown in Figure 1 is two cut-off valves of pneumatic piston, top actuator 21 includes cylinder 211 and the piston 212 (as shown in Figure 5) that is arranged in this cylinder 211 at this moment, in this embodiment, adopt between cylinder 211 and this support 221 and be threaded.
Embodiment two shown in Figure 2 is two cut-off valves of air bladder, top actuator 21 includes down membrane cover 215, diaphragm 216 and last membrane cover 217 at this moment, diaphragm 216 is clipped between the upper and lower membrane cover 217,215 and bolt locking connects (showing as Fig. 7), simultaneously in this embodiment, between following membrane cover 215 and the support 221 also employing be threaded.
When two cut-off valves of Pneumatic piston with same specification are replaced with two cut-off valves of air bladder, as long as replace with the top actuator of diaphragm type cut-off valve after the top actuator of taking-up piston type cut-off valve, similarly, just two cut-off valves of air bladder of same specification can be replaced with two cut-off valves of pneumatic piston, so dismounting of the present utility model is simple and convenient, model is exchanged fast, brings its versatility stronger.And, also very convenient when changing or keeping in repair the part (as piston, film etc.) in the actuator.
