Abstract
The invention provides a self-driven air charging valve, which comprises a valve body, a rubber valve seat and a butterfly plate, wherein the rubber valve seat is arranged in the valve body; the valve body is provided with an air inlet communicated with an air bag cavity formed between the valve body and the rubber valve seat; an air cylinder is also arranged above the air inlet; the air cylinder is divided into an upper cavity and a lower cavity; the diameter of the upper cavity is larger than that of the lower cavity; the inside of the upper cavity is provided with an upper piston, the inside of the lower cavity is provided with a lower piston, and the upper piston is connected with the lower piston through a connecting rod; an air pipe is also arranged on a pipeline; the air pipe is divided into an upper path and a lower path; the upper path is provided with a regulating valve 1 communicated with the upper cavity of the air cylinder, the lower path is serially connected with the regulating valve 2, a solenoid valve 1 and a check valve which are communicated with the lower cavity of the air cylinder; and the upper cavity at the other side of the air cylinder is communicated with the lower cavity through the air pipe, and the air pipe is provided with a solenoid valve 2. The self-driven air charging valve has the advantages that a certain gap is reserved among seal pairs in the process of opening and closing the valve to open and close the valve in the way of zero driving torque; and the air charging valve inflates air through the pressure of media in the pipeline without additional energy sources.
Description
Technical field
The present invention relates to a kind of valving, particularly relate to a kind of butterfly valve.
Background technique
At the butterfly valve of every profession and trade use, its sealing is to realize that by the extrusion-deformation between rubber valve seat and the butterfly plate sealed increscence amount is wayward at present, and keying moment is big.
Summary of the invention
Wayward in order to overcome existing butterfly valve sealed increscence amount, open and close the big deficiency of moment, the invention provides a kind of butterfly valve that opens and closes moment that do not have.
The technical solution adopted for the present invention to solve the technical problems is a kind of self-driven air charging valve, comprises valve body, rubber valve seat, butterfly plate, and rubber valve seat is installed in the valve body, has inlet hole on the valve body, communicates with the airbag chamber that forms between valve body and the rubber valve seat; A cylinder also is equipped with in the inlet hole top, and cylinder divides two chambeies up and down, and the diameter of epicoele has upper piston greater than the diameter of cavity of resorption in the epicoele, lower piston is arranged in the cavity of resorption, and upper piston is connected by connecting rod with lower piston; Also dress is connected with a tracheae on pipeline, and tracheorrhaphy is the road up and down, sets out on a journey modulating valve one is housed communicates with the epicoele of cylinder, is connected in series modulating valve two, solenoid valve one, one-way valve on the following road and communicates with the cavity of resorption of cylinder; Opposite side epicoele at cylinder is connected by tracheae with cavity of resorption, and solenoid valve two is housed on the tracheae.
Solenoid valve one, solenoid valve two are two-position two-way solenoid valve, and a filter also is housed on the tracheae.
The invention has the beneficial effects as follows that valve keeps a certain amount of gap between the sealing pair in switching process, realize zero driving moment switch, the pressure medium inflation in tube road does not need the energy that adds, sealing and circulating, and noiseless, pollution-free.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Fig. 2 is a pneumatic schematic diagram.
Among the figure: 1. modulating valve one; 2. cylinder; 3. epicoele; 4. upper piston; 5. connecting rod; 6. solenoid valve two; 7. lower piston; 8. cavity of resorption; 9. one-way valve; 10. solenoid valve one; 11. modulating valve two; 12. valve body; 13. inlet hole; 14. airbag chamber; 15. rubber valve seat; 16. filter; 17. tracheae; 18. pipeline; 19. butterfly plate.
Embodiment
As shown in Figure 1, 2, a kind of self-driven air charging valve comprises valve body 12, rubber valve seat 15, butterfly plate 19, and rubber valve seat 15 is installed in the valve body 12, has inlet hole 13 on the valve body 12, communicates with the airbag chamber 14 that forms between valve body 12 and the rubber valve seat 15; A cylinder 2 also is equipped with in inlet hole 13 tops, and cylinder is two chambeies about in the of 2 minutes, and the diameter of epicoele 3 has upper piston 4 greater than the diameter of cavity of resorption 8 in the epicoele 3, lower piston 7 is arranged in the cavity of resorption 8, and upper piston 4 is connected by connecting rod 5 with lower piston 8; Also dress is connected with a tracheae 17 on pipeline 18, and tracheae 17 minutes is the road up and down, sets out on a journey modulating valve 1 is housed communicates with the epicoele 3 of cylinder 2, is connected in series modulating valve 2 11, solenoid valve 1, one-way valve 9 on the following road and communicates with the cavity of resorption 8 of cylinder 2; Opposite side epicoele 3 at cylinder 2 is connected by tracheae 17 with cavity of resorption 8, and solenoid valve 26 also is housed on the tracheae 17.Solenoid valve 1, solenoid valve 26 are two-position two-way solenoid valve, and a filter 16 also is housed on the tracheae 17.
Fig. 2 is a pneumatic schematic diagram, (this moment, solenoid valve 1 and solenoid valve 26 were in power failure state to enter the epicoele 3 of cylinder 2 and cavity of resorption 8 after medium filters by filter 16 respectively, the epicoele 3 and the cavity of resorption 8 of cylinder 2 are not communicated with), because upper piston 4 areas are greater than lower piston 7 areas, make the pressure of the pressure of epicoele 3 greater than cavity of resorption 8, also promptly be higher than pressure medium, cavity of resorption 8 is the airbag chamber 14 of UNICOM's rubber valve seat 15 always, rubber valve seat 15 is pressed to butterfly plate 19 under airbag chamber 14 pressure effects, by regulating modulating valve 1 and modulating valve 2 11, produce essential seal pressure, thereby realize sealing.
When driving valve, solenoid valve 1 and solenoid valve 26 are all, the import of cavity of resorption 8 is blocked, cavity of resorption 8 and epicoele 3 direct UNICOMs, thereby make airbag chamber 14 pressure identical with pressure medium, rubber valve seat 15 is thrown off with butterfly plate 19 with returning to free state in the effect of rubber elasticity power, realizes zero driving moment unlatching.
