A new dual-purpose valve

Abstract

The invention discloses a novel dual purpose valve. The two ends of a valve body are provided with symmetrical flanges which are communicated through a cylindrical pipeline, the upper end of the middle of the valve body is provided with a valve deck which is connected with the valve body through a bolt, a valve plate and a filter screen which are arranged at a liquid inlet end and a liquid outlet end of the cylindrical pipeline respectively are arranged inside the portion, at the lower end of the valve deck, of the valve body, a drain outlet is formed in the valve bottom under the valve deck, and a drain plug is installed in the drain outlet. The valve plays two roles of combing a gate valve with a filtering valve and isolating the gate valve from the filtering valve, the cylindrical pipeline is divided into three cavities, the valve plate can bear pressure, the anti-counter-flow effect of the valve can be achieved, the flow capacity can be controlled, and the overall structure is simple and practical. Under the filtration function of the filter screen, impurities in liquid are discharged through the drain outlet formed in the valve bottom, the filtration capacity is high, the volume is small, setting of the equipment is achieved, the maneuverability of use is great, and the novel dual purpose valve can be suitable for local processing of some sewage.

Description

technical field [0001] The invention belongs to the technical field of valve equipment, and in particular relates to a novel dual-purpose valve. Background technique [0002] A valve is a mechanical device that controls the flow, flow direction, pressure, temperature, etc. of a flowing fluid medium, and a valve is a basic component in a piping system. Valve fittings are technically the same as pumps and are often discussed as a separate category. The valve can be operated manually or by handwheel, handle or pedal, and can also be controlled to change the pressure, temperature and flow of the fluid medium. Valves can operate continuously or repeatedly in response to these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used according to the needs of external inputs. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel va...

AI Technical Summary

Problems solved by technology

At present, the filtration appears in front of people with large-scale filtration systems, but for workshops or enterprises with a small amount of sewage, it is very wasteful to filter resources, so it is very important to study a small pressure filter that can partially treat some sewage

Existing valves generally do not have a filtering function, and the liquid circulates in the pipeline. Due to the environment or the influence of metal pipelines during transportation, granular impurities are likely to be produced in the circulating medium, and these impurities flow through the pipeline continuously with the medium. Each component in the pipeline is easy to cause wear to the valves in the pipeline, and damage the precision of instruments such as water meters with high sensitivity, which will seriously affect the normal operation of the valves, and eventually lead to failures in the pipeline system, reducing its service life and increasing Maintenance costs
