Foreign matter discharging spherical valve

Abstract

The invention relates to the technical field of valve body manufacturing, in particular to a foreign matter discharging spherical valve. The foreign matter discharging spherical valve is composed of avalve body, a water inlet connecting pipe and a water outlet connecting pipe. The two ends of the valve body communicate with the water inlet connecting pipe and the water outlet connecting pipe correspondingly. The foreign matter discharging spherical valve is characterized in that the valve body is spherical, the spherical valve body is internally provided with a spherical inner cavity internally provided with a spherical valve core, and the middle of the spherical valve core is provided with an X-shaped fluid channel; the section of the fluid channel presents that openings are gradually enlarged from the middle towards the two ends and are symmetrical; a foreign matter and air discharging opening is formed in the position, on one side of the water outlet connecting pipe, of the valve body, and a foreign matter and air discharging pipe is arranged at the foreign matter and air discharging opening; the diameter of each end opening of the fluid channel is larger than the maximum distance between the water outlet connecting pipe and the foreign matter and air discharging pipe; and the outer side face of the spherical valve core is connected with an external rotating handle througha rotating rod. By rotating the handle, three states, namely, closing, opening and foreign matter discharging, of the X-shaped fluid channel of the spherical valve core are achieved, and the foreign matter discharging spherical valve has the advantages that the structure is simple, high-point air discharging and low-point sewage discharging are both achieved, sampling is convenient, and pressure and temperature measuring is simple.

Description

technical field [0001] The invention relates to the technical field of valve body production, in particular to an object rejection ball valve with simple structure, high-point exhaust and low-point sewage discharge, convenient sampling, and simple pressure and temperature measurement. Background technique [0002] As we all know, there are T-type and L-type three-way ball valves. The T-type can make three orthogonal pipes communicate with each other and cut off the third channel, which plays the role of diversion and confluence. The L-type three-way ball valve can only connect two orthogonal pipes. The pipeline cannot keep the third pipeline connected to each other at the same time, and it only plays a distribution role. The L-shaped three-way ball valve is used to change the flow direction and connect or cut off the medium in the road. The L-type three-way ball valve can also switch the flow direction of the medium in the pipeline and connect or close two channels perpendic...

AI Technical Summary

Problems solved by technology

[0003] At present, the three-way ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It cannot remove foreign matter in the pipeline when the one-way fluid pipeline is working normally, or has a great influence on the fluid during the exclusion process. , and in order to achieve sewage discharge and exhaust in the traditional process, special sewage discharge or exhaust valves need to be installed on the low or high point pipelines, which not only increases the installation cost, but also increases the maintenance cost of the pipeline
