Which comprises a spherical valve core (2) arranged in a valve body (1), sealing rings (6) at the two ends of the spherical valve core (2) and a valve rod (5) for driving the spherical valve core (2) to rotate, and is characterized in that external threads (7) are arranged on connecting sections (8) at the two ends of the valve body (1), and two rubber tubes (11) with rubber tube ring edges (9) are connected to the connecting sections (8) through pressing caps (10). The valve bank has the advantages of being simple and small in structure, capable of meeting the requirement for low cost used under normal pressure and convenient to disassemble and assemble.

Description

Technical Field

[0001] The utility model relates to a valve component, in particular to a double-flexible-joint soft-connection valve group used in a toilet. Background Art

[0002] The utility model is an improvement on the prior art, especially the improvement on patent number ZL202221167742.X. In my country, most urban residents live in "apartment-style" residential buildings, where water supply and drainage are shared. Drainage blockages often occur on the first floor or the ground floor. If they are not discovered and cleared in time, the sewage / dirt in the sewer will flow back from the blockage to fill the sewer pipe, and then overflow from the toilets and drainage leaks of the residents closest to the blockage. This unbearable experience, especially for residents living in old residential areas, may have been encountered.

[0003] The solution of the applicant's prior patent ZL202221167742.X is to install a valve group in the toilet, so that the toilet is under controlled discharge or not in use, that is, when no one is at home or there is a blockage, the toilet drain valve can be closed to avoid the above annoying situation. The valve group structure in the original patent is composed of many parts. If it is installed in a relatively limited space in the toilet, it needs to be carefully crafted, which will inevitably bring cost problems. It is the original intention of the improvement of this utility model to consider using a valve group with a simpler and more compact structure, easy operation, and easy installation and replacement. Utility Model Content

[0004] The utility model aims to provide a double flexible joint valve group to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-flexible soft-connection valve group, including a spherical valve core 2 arranged in a valve body 1, and sealing rings 6 at both ends of the spherical valve core 2, and a valve stem 5 for driving the spherical valve core 2 to rotate, characterized in that: external threads 7 are provided on the connecting sections 8 at both ends of the valve body 1, and two hoses 11 with hose ring edges 9 are connected to the connecting sections 8 through a pressure cap 10.

[0006] It also includes: the hose 11 is a straight tube of equal diameter, one end of which is provided with an outward-turned annular hose ring edge 9 larger than the tube diameter, and the outer end surface of the hose ring edge 9 is an annular plane; the outer circumferential surface of the other end is provided with a clamp groove 12.

[0007] Compared with the prior art, the utility model has the beneficial effects that the valve group has a simple and compact structure, meets the low-cost characteristics of being used under normal pressure, and is easy to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a sectional view of the main view of the principle diagram of the utility model.

[0009] Figure 1 There is no definite proportional relationship among the components. In order to show the new invention more clearly, there are partial enlargements, simple drawings of common knowledge parts, omissions, etc. Parts in each figure: 1. Valve body; 2. Ball valve core; 3. Plug joint; 4. Connection groove; 5. Valve stem; 6. Sealing ring; 7. External thread; 8. Connection section; 9. Hose ring edge; 10. Pressure cap; 11. Hose; 12. Clamp groove. DETAILED DESCRIPTION

[0010] The following will be combined with the attached embodiment of the present invention Figure 1 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0011] In the utility model, the double flexible joint valve group includes a spherical valve core 2 arranged in a valve body 1, sealing rings 6 at both ends of the spherical valve core 2, and a valve stem 5 for driving the spherical valve core 2 to rotate, which are the same as the plastic one-time injection-molded ball valve in the prior art. The different structure is that: an external thread 7 is provided on the connecting section 8 at both ends of the valve body 1, and two hoses 11 with hose ring edges 9 are connected to the connecting section 8 through a pressure cap 10. It also includes: the hose 11 is a straight tube of equal diameter, one end is provided with an outward-turned annular hose ring edge 9 larger than the pipe diameter, and the outer end face of the hose ring edge 9 is an annular plane; on the outer circumferential surface of the other end, a clamp groove 12 is provided. There is no other structure in the valve group that is difficult to understand. The installation and use of the valve group need to be briefly explained: because this valve group is installed on the horizontal section of the drain pipe at the lower end of the toilet drain bend, and this section of the drain pipe of the toilet is made of fired ceramic material, the pipe diameter is not as precise as that of metal machined parts, and the space for installation operation is very cramped, and it does not need to bear pressure. It is not suitable for general hard pipe connection, and it is sufficient to use soft rubber hose sleeves and clamps to tighten.

[0012] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
