Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the delivery channel of the valve is too single, and provide a multi-channel valve. The multi-channel valve consists of a main pipe corresponding to a branch pipe, and the valve can perform multiple ways of switching on and off the fluid in the branch pipe. control, in addition, the valve stem of the valve can be locked, increasing the man-operability and stability of the valve

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as Figures 1 to 12 The shown multi-channel valve includes one main stream pipe 10, six branch pipes 11 and one valve housing integrally formed. The structural strength and sealing performance of the three can be greatly enhanced after integral molding. The sealing ring 6, the fixed block 7 and the valve stem 3, the valve stem 3 passes through the sealing ring 6 and the fixed block 7, the valve stem 3 can rotate and move up and down, the sealing ring 6 is used to increase the airtightness between the valve housing and the valve stem 3 To prevent liquid from flowing out from the gap between the valve stem 3 and the valve body, the fixing block 7 is used for the installation of the valve stem 3 to prevent the valve stem 3 from shaking or falling off.

[0034] The bottom of the branch pipe 11 is also provided with an auxiliary pipe 110 , and the auxiliary pip...

Abstract

The invention discloses a multichannel valve. The multichannel valve comprises a main flow pipe and a plurality of branch flow pipes. Valve elements are arranged in the branch flow pipes, an eccentric structure for controlling the valve elements is arranged at the bottom of a valve rod, the valve rod is rotated to drive the eccentric structure to rotate, control over opening and closing of the valve elements in the branch flow pipes can be achieved through the eccentric structure, and control over the flowing transportation directions of multiple kinds of fluid of the multichannel composite control valve can be achieved. The outer side of the valve rod above a valve shell is sleeved with a locking mechanism for locking the valve rod, and therefore the valve rod can be locked.

Description

technical field [0001] The invention relates to the technical field of hardware valve equipment, which is a multi-channel valve. Background technique [0002] At present, the structure of the valve includes a valve body, a valve cavity is arranged in the valve body, a valve core is installed in the valve cavity, and a valve stem is connected to the valve core. Valves with multiple tributaries are used in various fields such as agriculture and industry. However, most of the existing valves cannot realize multi-directional flow (that is, have multiple direct currents), and most of them can only achieve a single single-channel flow, which cannot satisfy people. Diverse demands on valves. In addition, the current valve control is also unstable, and there is no necessary control over the stability of the valve stem, which can easily lead to the flow disorder and cross-flow stability of multi-channel valves. Contents of the invention [0003] The purpose of the present inventi...
