Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a connecting valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems.

[0003] However, since the connection between the valve and the pipeline is achieved by flange, leakage is likely to occur when the joint position is not tight enough. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a connecting valve to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a connecting valve, comprising a valve, a joint flange is installed at the outer end of the valve, inner clamping pads are installed on the inner sides of both ends of the valve, a conical connecting pipe is installed on the outer side of the inner clamping pad, a leak-proof gasket is arranged on the outer side of the conical connecting pipe, a connecting pipe is arranged on the outer side of the valve, a transfer flange is installed at the outer end of the connecting pipe, a magnetic pad is installed at the inner end of the connecting pipe, and a connecting pipe sleeve is installed on one side of the magnetic pad located on the outer side of the conical connecting pipe.

[0006] As a further solution of the utility model: a flange groove is provided on the side surface of the joint flange, and a clamping gasket is installed at a position on the side surface of the adapter flange corresponding to the flange groove.

[0007] As a further solution of the utility model: a valve seat is installed on the upper surface of the valve, a valve stem is installed inside the valve seat, a switch knob is installed on the upper end of the valve stem, and a valve core is installed on the lower end of the valve stem.

[0008] As a further solution of the utility model: the anti-leakage gasket is a rubber component, and the inner clamping gasket is clamped with the connecting pipe sleeve.

[0009] As a further solution of the utility model: the conical connecting pipe is fixedly connected to the inner clamping gasket by bolts, and the inner clamping gasket is fixedly connected to the valve.

[0010] As a further solution of the utility model: the clamping pad is clamped with the flange clamping groove.

[0011] As a further solution of the utility model: the connecting pipe sleeve is connected to the magnetic pad by magnetic adsorption, and the magnetic pad is fixedly connected to the connecting pipe.

[0012] As a further solution of the utility model: the valve stem is movably connected to the valve seat in meshing engagement.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The leak-proof gasket on the outside of the conical connecting pipe will be squeezed and deformed by the connecting pipe sleeve to reduce the gap between the connecting pipe sleeve and the conical connecting pipe. When the water flows through the inner position of the conical connecting pipe, the water pressure increases. When the water passes through the end of the conical connecting pipe as a whole, the water flow rate becomes faster, ensuring the waterproofness of the connection between the valve and the connecting pipe.

[0015] 2. The connecting pipe sleeve is adsorbed on the side surface of the magnetic pad as a whole, and the conical connecting pipe is fastened with bolts at the inner pad position inside the valve. Therefore, the installation situation can be selected according to the different waterproof performance requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.

[0023] like Figure 2-4 As shown, in this embodiment, a flange groove 201 is provided on the side surface of the joint flange 2, a clamping gasket 6 is installed at the position of the flange groove 201 on the side surface of the adapter flange 5, the clamping gasket 6 is clamped with the flange groove 201, a valve seat 7 is installed on the upper surface of the valve 1, a valve stem 301 is installed inside the valve seat 7, the valve stem 301 is engaged and movably connected with the valve seat 7, a switch knob 3 is installed on the upper end of the valve stem 301, and a valve core 302 is installed on the lower end of the valve stem 301.

[0024] The working principle of the utility model is: when installing and connecting, the conical connecting pipe 102 is placed on the position of the inner clamping pad 101 inside the valve 1, and then bolts are used to tighten it, and then the connecting pipe sleeve 402 is placed on the inner side end of the connecting pipe 4, and the connecting pipe sleeve 402 is adsorbed on the side surface of the magnetic pad 401, and then the joint flange 2 at the end of the valve 1 and the adapter flange 5 at the end of the connecting pipe 4 are connected, and the clamping pad 6 and the flange clamping groove 201 are matched and installed, and the conical connecting pipe 102 is inserted into the interior of the connecting pipe sleeve 402 as a whole, The leak-proof gasket 103 on the outside of the conical connecting tube 102 will be squeezed and deformed by the connecting tube sleeve 402 to reduce the gap between the connecting tube sleeve 402 and the conical connecting tube 102. The conical connecting tube 102 is set to have a conical structure. Therefore, when the water flows through the internal position of the conical connecting tube 102, the water pressure becomes larger. After the water passes through the end of the conical connecting tube 102 as a whole, the water flow rate becomes faster, preventing water from flowing out through the gap of the valve 1 between the connecting tube sleeve 402 and the conical connecting tube 102 to the joint position of the joint flange 2 and the adapter flange 5, thereby ensuring the waterproofness of the connection between the valve 1 and the connecting pipe 4.
