The basic function of a valve is to open and close fluid passages in pipelines, or to regulate the flow rate and pressure of fluids. Depending on the application requirements, there are many types of valves, each with its own specific design and operating characteristics.

[0003] In the prior art, most valves are in the shape of an inverted "T", which is inconvenient to install in a small space and to operate. Therefore, this utility model proposes a new type of valve. Utility Model Content

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0024] like Figures 1-4 As shown, a novel valve includes a left valve body 1 and a right valve body 2. The left valve body 1 and the right valve body 2 are flanged together to form a valve cavity 3 inside the valve. The left valve body 1 has a liquid outlet pipe 4 at its left end, which is connected to the left valve body 1. The right valve body 2 has a liquid inlet pipe 5 at its right end, which is connected to the right valve body 2. The valve cavity 3 is provided with a valve core mechanism coaxially arranged with the valve cavity 3. The outer wall of the liquid inlet pipe 5 is provided with a threaded part 17, and a rotating mechanism is threadedly connected to the threaded part 17.

[0025] In the above technical solution, by setting the valve core mechanism and the valve cavity 3 coaxially, the valve of this utility model is tubular in shape, which is more compact than the traditional inverted "T" shaped valve structure and more convenient to use in narrow spaces.

[0026] In this utility model, the valve core mechanism includes a valve core body 6 and a set of connecting plates 7. The valve core body 6 is located inside the valve cavity 3, and the set of connecting plates 7 is symmetrically arranged on the valve core body 6. A valve stem 8 is detachably and fixedly connected to the end face of the connecting plate 7 near the right valve body 2.

[0027] In this utility model, a circular abutment groove 9 coaxial with the valve core body 6 is provided on the end face of the left valve body 1 away from the right valve body 2. A sealing ring 10 is provided in the circular abutment groove 9, and the valve core body 6 can abut against the circular abutment groove 9.

[0028] In this utility model, a set of sealing parts 11 are provided inside the right valve body 2, and a set of packing grooves 12 are provided on the right end face of the right valve body 2. The set of packing grooves 12 are located inside the sealing parts 11, and a through hole 13 is provided at the bottom of the packing groove 12. The valve stem 8 is in telescopic cooperation with the through hole 13.

[0029] In this utility model, the seasoning trough is filled with sealing filler 14, and the seasoning trough position on the right end face of the right valve body 2 is detachably connected to the filler cover plate 15 by bolts. The filler cover plate 15 is sleeved with the valve stem 8.

[0030] In this utility model, the rotating mechanism includes a rotating sleeve 16, which is threadedly connected to the threaded portion 17. A circular groove 18 is provided on the end face of the rotating sleeve 16 near the right valve body 2. An annular baffle 19 is threadedly connected inside the circular groove 18. An annular through hole 20 is formed between the annular baffle 19 and the threaded portion 17. An annular cavity 21 is formed between the annular baffle 19 and the right wall of the circular groove 18.

[0031] In this utility model, the valve stem 8 passes through the annular through hole 20, and a circular limiting plate 22 is provided at the right end of the valve stem 8. The annular limiting plate is located in the annular cavity 21.

[0032] The working principle of this novel valve is as follows:

[0033] In use, rotate the rotating sleeve 16. The rotating sleeve 16 rotates on the threaded part 17 and moves to the left or right. When the rotating sleeve 16 moves to the left on the threaded part 17, the annular cavity 21 and the circular limiting plate 22 at the end of the valve stem 8 rotate and engage. Driven by the rotating sleeve 16, the circular limiting plate 22 is pushed to the left end of the valve body 1. At this time, the valve stem 8 moves in the through hole 13, driving the valve core body 6 to move to the left. When the valve core body 6 moves into the circular abutment groove 9 and abuts tightly, the valve core body 6 squeezes and deforms the sealing ring 10, sealing the gap between the valve core body 6 and the circular abutment groove 9, thus completing the valve closure. The valve opening is achieved by reversing the operation.

[0034] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
