Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic ball valves, and more specifically to a pneumatic ball valve for quantitative filling. Background Art

[0002] A pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The pneumatic actuator has a relatively fast execution speed and is usually called a pneumatic quick-cut ball valve. Pneumatic ball valves are usually equipped with various accessories, such as solenoid valves, air source processing triplet, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control. The valve can be switched on and off in the control room without the need to go to the site or high altitude or dangerous places for manual control, which saves human resources, time and safety to a great extent.

[0003] The existing pneumatic ball valve is usually controlled manually in the control room when it is switched on and off. Manual control of the pneumatic ball valve will cause a certain error in the switching time of the pneumatic ball valve, which will lead to a certain deviation in the quantitative filling of the pneumatic ball valve. For this reason, we propose a pneumatic ball valve for quantitative filling. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a pneumatic ball valve for quantitative filling to solve the problems existing in the above background technology.

[0005] The utility model provides the following technical solution: a pneumatic ball valve for quantitative filling, comprising a valve body, one side of the surface of the valve body is connected with a water inlet, the other side of the surface of the valve body is connected with a water outlet, a ball is movably connected to the inner side of the valve body, an upper shaft is fixedly connected to the surface of the ball, an actuator is fixedly connected to the top of the upper shaft, a mounting ring is fixedly connected to the surface of the water outlet, a connecting block is fixedly connected to the surface of the mounting ring, a pressure sensor is fixedly connected to one side of the top of the connecting block, a metering sensor is fixedly connected to the other side of the top of the connecting block, and a transmission module is provided on the connecting block;

[0006] Furthermore, a slide groove is provided on the surface of the water inlet, a slider is movably connected to the inner side of the slide groove, a first sealing layer is fixedly connected to one side of the surface of the slider, a second sealing layer is fixedly connected to the surface of the first sealing layer, a positioning column is passed through the other side of the surface of the slider, a pull ring is fixedly connected to the top of the positioning column, and a stopper is fixedly connected to one end of the inner side of the slide groove.

[0007] Furthermore, a reinforcement mechanism passes through one side of the mounting ring, a gasket is fixedly connected to the surface of the reinforcement mechanism, and a mounting nut is fixedly connected to the side of the gasket away from the mounting ring. The mounting ring can be quickly installed on the surface of the water outlet through the reinforcement mechanism, thereby quickly completing the installation of the pressure sensor and the metering sensor.

[0008] Furthermore, there are several sliders, positioning posts and pull rings, which are symmetrically distributed and equally grouped on the inner side of the slide groove. By sliding multiple sliders on the inner side of the slide groove, the first sealing layer and the second sealing layer can be displaced at the same time.

[0009] Furthermore, a limiting hole adapted to the positioning column is opened on the inner side of the slide groove, and one end of the positioning column passes through the slider and extends to the inner side of the slide groove. The position of the slider on the inner side of the slide groove can be limited through the limiting hole on the inner side of the slide groove adapted to the positioning column, thereby preventing the slider from self-driving the first sealing layer and the second sealing layer to move on the inner side of the slide groove.

[0010] Furthermore, one side of the gasket and one side of the mounting ring are in contact with each other, and the inner side of the mounting nut and one end of the surface of the reinforcement mechanism are in contact with each other. By fitting the gasket and the mounting ring together, the vibration of the liquid transmitted to the reinforcement mechanism through the mounting ring for a long time can be buffered, thereby preventing the reinforcement mechanism from loosening due to long-term vibration.

[0011] Furthermore, the inner side of the first sealing layer is in contact with the surface of the water inlet, and the first sealing layer and the second sealing layer are both made of rubber. By the first sealing layer and the water inlet being in contact with each other, the connection between the water inlet and the water pipe can be sealed, thereby improving the sealing and usability of the starting ball valve after installation.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model uses the pressure sensor and the metering sensor to transmit the information to the control module through the transmission module after detecting a certain pressure and fluid flow, which is beneficial for the control module to control the opening and closing of the pneumatic ball valve by itself, without the need for manual opening and closing of the pneumatic ball valve, thereby improving the accuracy of quantitative filling of the pneumatic ball valve and enabling the pneumatic ball valve to perform quantitative control on the filling of the fluid.

[0014] 2. The utility model is provided with a sliding block on the inner side of the slide groove, so that the sliding block drives the first sealing layer and the second sealing layer to seal the connection between the water inlet and the pipeline, which is beneficial to improve the sealing and usability of the starting ball valve, and prevents the connection between the water inlet and the pipeline from seepage, thereby affecting the accuracy of positioning and filling of the starting ball valve.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0022] Reference Figure 1-5 The utility model provides a pneumatic ball valve for quantitative filling, including a valve body 1, one side of the surface of the valve body 1 is connected with a water inlet 2, the other side of the surface of the valve body 1 is connected with a water outlet 3, the inner side of the valve body 1 is movably connected with a ball 4, the surface of the ball 4 is fixedly connected with an upper shaft 5, the top of the upper shaft 5 is fixedly connected with an actuator 6, the surface of the water outlet 3 is fixedly connected with a mounting ring 7, the surface of the mounting ring 7 is fixedly connected with a connecting block 8, one side of the top of the connecting block 8 is fixedly connected with a pressure sensor 9, the other side of the top of the connecting block 8 is fixedly connected with a metering sensor 10, and the connecting block 8 is provided with a transmission module 11;

[0023] Among them, a slide groove 15 is opened on the surface of the water inlet 2, and a slider 16 is movably connected to the inner side of the slide groove 15, a first sealing layer 17 is fixedly connected to the surface of the slider 16 on one side, and a second sealing layer 18 is fixedly connected to the surface of the first sealing layer 17, and a positioning column 19 passes through the other side of the surface of the slider 16, and a pull ring 20 is fixedly connected to the top of the positioning column 19, and a stopper 21 is fixedly connected to one end of the inner side of the slide groove 15.

[0024] Among them, a reinforcement mechanism 12 passes through one side of the mounting ring 7, a gasket 13 is fixedly connected to the surface of the reinforcement mechanism 12, and a mounting nut 14 is fixedly connected to the side of the gasket 13 away from the mounting ring 7. The gasket 13 can prevent the mounting nut 14 from loosening due to long-term vibration, making it impossible to fix the position of the reinforcement mechanism 12.

[0025] Among them, the number of sliders 16, positioning columns 19 and pull rings 20 is several, and several sliders 16, positioning columns 19 and pull rings 20 are symmetrically distributed and equally grouped on the inner side of the slide groove 15. The positions of multiple sliders 16 on the inner side of the slide groove 15 can be restricted at the same time through multiple positioning columns 19.

[0026] Among them, a limiting hole adapted to the positioning column 19 is opened on the inner side of the slide groove 15, and one end of the positioning column 19 passes through the slider 16 and extends to the inner side of the slide groove 15. By pulling out the positioning column 19 from the limiting hole on the inner side of the slide groove 15, the positioning column 19 does not limit the position of the slider 16, so that the slider 16 drives the first sealing layer 17 and the second sealing layer 18 to move on the inner side of the slide groove 15.

[0027] Among them, one side of the gasket ring 13 is in contact with one side of the mounting ring 7, and the inner side of the mounting nut 14 is in contact with one end of the surface of the reinforcement mechanism 12. By fitting the mounting nut 14 and the reinforcement mechanism 12 together, the reinforcement mechanism 12 can be reinforced to prevent the reinforcement mechanism 12 from loosening, thereby causing the connection between the mounting ring 7 and the water outlet 3 to loosen.

[0028] Among them, the inner side of the first sealing layer 17 is in contact with the surface of the water inlet 2, and the materials of the first sealing layer 17 and the second sealing layer 18 are both rubber materials. Since the materials of the first sealing layer 17 and the second sealing layer 18 are rubber materials, the connection between the water inlet 2 and the pipeline can be sealed to prevent the fluid from leaking out of the connection between the pipeline and the water inlet 2.

[0029] The working principle of the utility model is as follows: when it is necessary to use a starting ball valve to quantitatively fill the fluid, firstly, the mounting ring 7 is sleeved on the surface of the water outlet 3, and then the reinforcing mechanism 12 is used to penetrate the mounting ring 7 to limit the position of the mounting ring 7 on the surface of the water outlet 3, and then the gasket 13 and the mounting nut 14 are sleeved on the surface of the reinforcing mechanism 12 to reinforce the reinforcing mechanism 12, and then the mounting ring 7 can be installed on the surface of the water outlet 3. At this time, when the fluid passes through the water outlet 3, the pressure sensor 9 and the metering sensor 10 at the top of the connecting block 8 will detect the pressure generated by the fluid and the metering of the fluid passing through. When the pressure and the metering reach a certain level, the transmission module 11 will transmit the information to the control room. When controlled, the actuator 6 will be controlled to drive the upper shaft 5 to rotate, so that the ball 4 rotates inside the valve body 1, and the internal space of the ball 4 is sealed, thereby completing the quantitative filling of the fluid; in addition, when the water inlet 2 is connected to the pipeline, the pull ring 20 is pulled upward, so that the pull ring 20 drives the positioning column 19 to withdraw from the limiting hole inside the slide groove 15, and then the slider 16 is slid, so that the slider 16 slides on the inside of the slide groove 15 and contacts the stopper 21, and then the positioning column 19 is reset to limit the position of the slider 16. At this time, the first sealing layer 17 and the second sealing layer 18 will seal the connection between the water inlet 2 and the pipeline, thereby improving the sealing and usability of the starting ball valve.
