Abstract
Description
Technical Field
[0001] This utility model relates to the field of C-type ball valve technology, specifically to an anti-clogging C-type ball valve. Background Technology
[0002] The C-type ball valve is a commonly used wear-resistant ball valve with a simple structure and good sealing performance. It consists of a valve body, valve cover, valve core, valve seat, and valve stem. The valve core has a C-shaped opening, hence the name C-type ball valve. The flow of media is controlled by rotating the valve core. When the valve core is rotated parallel to the pipeline axis, the media can pass smoothly; when the valve core is rotated 90 degrees so that the C-shaped opening is perpendicular to the pipeline axis, the valve core immediately cuts off the media, closing the valve. However, if the C-type ball valve is not used for a long time, the accumulation and solidification of impurities inside the valve body can easily cause blockage and jamming of the C-type valve core. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, an anti-clogging C-type ball valve is provided to solve the problem that when the C-type ball valve is not used for a long time, the accumulated and solidified impurities in the valve body can easily cause the C-type valve core to become blocked or stuck.
[0004] To achieve the above objectives, an anti-clogging C-type ball valve is provided, comprising: a C-type ball valve body, wherein a flow cavity is provided on the inner side of the C-type ball valve body.
[0005] A valve seat is embedded in the wall of the flow chamber. A C-shaped valve core is connected to the lower end wall of the flow chamber through a lower bearing. A second flushing nozzle and a first flushing nozzle are distributed on the front and rear sides of the C-shaped valve core. A connecting pipe is connected to the front end of the second flushing nozzle. The rear end of the first flushing nozzle is connected to the connecting pipe through a diverter pipe. A flushing pipe is sealed and screwed to the front end of the connecting pipe. A small high-pressure water pump is connected to the other end of the flushing pipe.
[0006] Furthermore, flange joints are welded to the left and right ends of the C-type ball valve body, and a valve stem is threaded to the upper end of the C-type ball valve body.
[0007] Furthermore, the lower end of the valve stem is connected to the upper end face of the C-type valve core via an upper bearing.
[0008] Furthermore, a small high-pressure water pump is fixedly installed on the front surface of the C-type ball valve body, and an inlet is provided on the lower end face of the small high-pressure water pump, with a water supply pipe connected to the surface of the inlet.
[0009] Furthermore, a connecting pipe is welded to the front end face of the C-type ball valve body; and a diverter pipe is connected to the right side of the connecting pipe.
[0010] Furthermore, a second flushing nozzle and a first flushing nozzle are embedded in the front and rear walls of the flow chamber; and valve seats are located at the right ends of the second flushing nozzle and the first flushing nozzle.
[0011] Furthermore, the spherical seal at the side end of the C-type valve core is fitted to the valve seat port.
[0012] The beneficial effects of this utility model are as follows: the anti-clogging C-type ball valve of this utility model utilizes a flushing pipe, a small high-pressure water pump, a first flushing nozzle, a second flushing nozzle, a diverter pipe, and a connecting pipe to form a flushing structure for the C-type ball valve. High-pressure water is delivered to the flushing nozzle through the flushing pipe, so that the first and second flushing nozzles, which are symmetrically embedded in the valve cavity, flush the contact end between the C-type valve core and the valve seat in the closed state. This flushes away the impurities attached to the contact end between the C-type valve core and the valve seat, effectively preventing the solidification of residual impurities in the valve over a long period of time and causing blockage. This facilitates the normal rotation and operation of the valve core in the C-type ball valve and ensures the stable control of the flow of the medium by the C-type ball valve.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figures 1 to 4 As shown, this utility model provides an anti-clogging C-type ball valve, including: a C-type ball valve body 1, and a flow chamber 12 provided on the inner side of the C-type ball valve body 1.
[0020] A valve seat 13 is embedded in the wall of the flow chamber 12. A C-type valve core 5 is connected to the lower end wall of the flow chamber 12 through a lower bearing 52. A second flushing nozzle 61 and a first flushing nozzle 6 are distributed on the front and rear sides of the C-type valve core 5. A connecting pipe 63 is connected to the front end of the second flushing nozzle 61. The rear end of the first flushing nozzle 6 is connected to the connecting pipe 63 through a diverter pipe 62. A flushing pipe 2 is sealed and screwed to the front end of the connecting pipe 63. A small high-pressure water pump 21 is connected to the other end of the flushing pipe 2.
[0021] When the C-type ball valve body 1 closes the internal medium flow channel, rotating the valve stem 4 drives the spherical surface of the C-type valve core 5 to rotate and seal against the valve seat 13 port. At this time, after the C-type ball valve body 1 is in the closed state, the water supply pipe 3 is connected to the small high-pressure water pump 21, and the small high-pressure water pump 21 is powered on and started, pressurizing the water flow transported by the water supply pipe 3 and delivering it to the flushing pipe 2. After passing through the diversion pipe 62 and the connecting pipe 63, the high-pressure water flow is delivered to the first flushing nozzle 6 and the second flushing nozzle 61 and sprayed out to flush the contact end of the C-type valve core 5 and the valve seat 13, flushing out the impurities attached to the contact end, avoiding the solidification of impurities that have been attached for a long time and hindering the rotation of the C-type valve core 5, and effectively preventing the solidified impurities remaining in the C-type ball valve body 1 from causing blockage.
[0022] In this embodiment, flange joints 11 are welded to the left and right ends of the C-type ball valve body 1, and a valve stem 4 is threadedly connected to the upper end of the C-type ball valve body 1. The lower end of the valve stem 4 is connected to the upper end face of the C-type valve core 5 through an upper bearing 51. The spherical surface of the side end of the C-type valve core 5 is sealed and fitted to the port of the valve seat 13.
[0023] In a preferred embodiment, the flange joint 11 is used to connect the C-type ball valve body 1 to the medium pipeline, allowing the medium to flow in from the right end and out from the left end of the C-type ball valve body 1. The valve stem 4 is used to drive the C-type valve core 5 to rotate within the cavity. When the C-type valve core 5 rotates and fits against the valve seat 13 port, the C-type ball valve body 1 is in a closed state, thereby blocking the continued flow of the medium.
[0024] In this embodiment, a small high-pressure water pump 21 is fixedly installed on the front surface of the C-type ball valve body 1. The lower end face of the small high-pressure water pump 21 is provided with a water inlet 22, and a water supply pipe 3 is connected to the surface of the water inlet 22. A connecting pipe 63 is welded to the front end face of the C-type ball valve body 1; and a diverter pipe 62 is connected to the right side of the connecting pipe 63. A second flushing nozzle 61 and a first flushing nozzle 6 are embedded in the front and rear walls of the flow chamber 12; and valve seats 13 are located at the right ends of the second flushing nozzle 61 and the first flushing nozzle 6.
[0025] As a preferred implementation, the small high-pressure water pump 21 can pressurize the water flow delivered by the water supply pipe 3 before delivering it to the flushing pipe 2. The flushing pipe 2 delivers the high-pressure water flow through the connecting pipe 63 and the diverting pipe 62 to the second flushing nozzle 61 and the first flushing nozzle 6 for spraying. This facilitates the flushing and cleaning of impurities attached to the contact end of the C-type valve core 5 and the valve seat 13, avoiding the blockage or jamming of the C-type valve core 5 caused by impurities that have solidified over a long period of time. This ensures the normal rotation and operation of the C-type valve core 5 inside the C-type ball valve body 1, ensuring the long-term and stable control of the flow of the medium by the C-type ball valve body 1. At the same time, it reduces the frequency of disassembling the C-type ball valve body 1 for cleaning and maintenance, making it easy to clean and preventing the C-type ball valve body 1 from becoming blocked.
[0026] This utility model of an anti-clogging C-type ball valve can effectively solve the problem that when a C-type ball valve is not used for a long time, the residual impurities in the valve body accumulate and solidify, which can easily lead to blockage and jamming of the C-type valve core. It effectively prevents the residual impurities in the valve from solidifying and causing blockage over a long period of time, facilitates the normal rotation and operation of the valve core in the C-type ball valve, and ensures the stable control of the flow of the medium by the C-type ball valve. It is suitable for anti-clogging C-type ball valves.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
