Description
Technical Field
The utility model relates to a control valve technical field especially relates to a colloid control valve.
Background
The existing control valve mainly comprises a valve body assembly and an actuator assembly (or an actuator system); they can be generally summarized in three categories: the first type adopts a metal valve body and a valve core, and an electric actuator or an air cylinder is added to realize automatic control; the second type is a valve with a metal valve body and a non-metal valve core, and is mainly used in special occasions; the third type is that the soft tube is made of nonmetal soft material, and the connection and disconnection are realized by the deformation of the soft tube. These control valves often have complicated structures and large volumes, are difficult to be applied to narrow and small space scenes, and have low applicability.
Disclosure of Invention
An object of the utility model is to provide a colloid control valve to solve the problem that proposes among the above-mentioned background art. In order to achieve the above object, the utility model provides a following technical scheme:
a colloidal control valve comprising:
a valve body including a first port and a second port; and
the air bag is arranged in the valve body and is communicated with an air valve;
the air valve inflates the air bag to drive the air bag to extend, and then the end part of the air bag is clamped with the first interface to seal the first interface.
Further, the air bag is made of colloid materials.
Further, the valve body is made of colloid materials, and the air bag is formed by inward bulges on the inner wall of the valve body.
Further, the gasbag includes pars contractilis and contact site, the inside steel wire ring that is provided with of pars contractilis, the inside steel sheet that is provided with of contact site.
Further, flanges are arranged on the outer sides of the first interface and the second interface.
The beneficial effects of the utility model reside in that: the utility model has simple structure, small volume and high applicability; the conveying device can be used in narrow and small space scenes, and can also adapt to the use scenes of conveying various corrosive articles by selecting and using appropriate colloid materials.
Drawings
Fig. 1 is a sectional view of the open state of the colloid control valve of the present invention.
Fig. 2 is a cross-sectional view of the closed state of the colloid control valve of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a colloid control valve includes:
a valve body 1 including a first port 11 and a second port 12; and
the air bag 2 is arranged in the valve body 1, and the air bag 2 is connected with an air valve 3 in a penetrating way;
the air valve 3 inflates the air bag 2 to drive the air bag 2 to extend, and the end part of the valve core is clamped with the first interface 11 to seal the first interface 11.
Specifically, when the control valve needs to be closed, an external air compressor inflates the air bag 2 in the air bag 2 through the air valve 3, the volume of air in the air bag 2 is gradually increased, the air bag 2 is further driven to gradually extend until the end part of the air bag 2 is clamped with the first interface 11 of the valve body 1 to seal the first interface 11, and a communication channel between the first interface 11 and the second interface 12 is disconnected, so that the control valve is closed; when the control valve needs to be opened, air in the air bag 2 is discharged outwards through the air valve 3, the air bag 2 is contracted and returned, the end part of the air bag 2 is driven to leave the first connector 11, the first connector 11 is opened, the first connector 11 is communicated with the second connector 12, and then the control valve is opened. The utility model discloses a control valve simple structure, the volume is less, and convenient control utilizes 2 modes of replacing the actuating mechanism drive valve core of traditional control valve of gasbag, is convenient for reduce the volume of control valve to be applicable to the narrow and small scene in space.
Furthermore, the valve body 1 is made of colloid material, and the air bag 2 is formed by the inward bulge of the inner wall of the valve body 1; the elasticity of the colloid enables the air bag 2 to smoothly stretch and retract, so that a proper colloid material is convenient to select and use to enable the control valve to adapt to the use scene of conveying various corrosive articles; the integrated structure of the control valve is convenient to produce in a mode of injecting glue through the model.
Further, the airbag 2 comprises a telescopic part 21 and a contact part 22, wherein a steel wire circular ring 211 is arranged inside the telescopic part 21, and a steel plate 221 is arranged inside the contact part 22; the expansion direction of the air bag 2 is shaped by using a steel wire ring 211; the steel plate 221 is used for shaping the contact part 22, so that the clamping between the contact part 22 and the first interface 11 is more stable and closed; to reinforce the structural strength of the airbag 2.
Further, flanges 4 are arranged on the outer sides of the first connector 11 and the second connector 12 and used for being connected with equipment at the inlet and outlet ends so as to install and fix the control valve.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent changes without departing from the technical scope of the present invention.
