AI Technical Summary

Problems solved by technology

The valve structure is complex and the operation is cumbersome
Due to the structural size limitation of the valve plate and the cam, the water distribution valve has a large structural size, and is generally only suitable for installation on water pipelines with large flow and low pressure.
[0005] The water supply system of existing walking water-saving irrigation equipment mostly uses two-position two-way industrial valves, adopts a series-parallel pipeline system structure, and installs a valve on each water branch pipe, and realizes water supply to different branch pipes by manipulating multiple valves control requirements, the pipeline system structure is complex, the installation space is large, the reliability is low and the operation is troublesome

Embodiment Construction

[0020] specific implementation plan

[0021] The structure of the present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0022] Such as figure 1 , figure 2 As shown, 1 is the valve body, 2 is the valve core, 3 is the water outlet hole, 4 is the balance hole, 5 is the valve cover, and 6 is the sealing ring. In this embodiment, the "O" type sealing ring is selected, and 7 is the adjusting gasket. 8 is a water inlet, 9 is a water outlet A, 10 is a water outlet B, and 11 is a handle.

[0023] In the present invention, a hollow cock-type valve core 2 is adopted, and one or more water outlet holes 3 that can communicate with the water outlet are opened on the conical surface of the valve core 2. In this embodiment, there is one water outlet hole. The water inlet 8 communicates with the cavity of the valve core 2, and there are multiple water outlets on the valve body 1. In this embodiment, there are two water outlet...

Abstract

A multiposition multi-ported cock belongs to a technological filed of industrial values, which includes a cock body, a water inlet and several water outlets disposed on the cock body. In the cock body is mounted a hollow cock spool and on the conical surface of the spool are opened one or several water intakes in communication with the water outlets. The water inlet is in communication with the hollow cavity of the spool.

Description

technical field [0001] The invention relates to a multi-position and multi-way plug valve, which belongs to the technical field of industrial valves. Background technique [0002] With the continuous development and innovation of walking water-saving irrigation equipment, the performance and function requirements of the equipment water supply system are constantly increasing. Many machines, such as water planters, spray irrigation machines, and injection irrigation machines, are equipped with water pumps. The pressure water sent by the water pumps should be able to supply water to different pipeline systems such as water tanks, irrigators, spray pipes, and injection irrigators. Control requirements. Similarly, the water supply and delivery (including oil and gas) pipeline systems in industry, agriculture, and life also have a large number of demands for water supply from water supply pipelines to different branch pipelines. The valves used in the prior art to meet this dem...
