Spot movement type measuring distributer capable of adjusting flow quantity

Abstract

The invention relates to a flow rate adjustable and inching type measuring distributor, comprising a cylinder, a high-pressure plunger type hydraulic cylinder, a thread-type adjustable apparatus, and a gas and liquid solenoid directional control valve, which is characterized in that: the output cylinder rod of the cylinder is rigidly connected with the output plunger of the high-pressure plunger type hydraulic cylinder; the thread-type adjust apparatus which can precisely adjust the output of the liquid volume of each inching is arranged at the other end of the cylinder; the air inlet of the cylinder is connected with the pneumatic solenoid directional control valve; the high-pressure plunger type hydraulic cylinder is connected with a liquid injection port through a normally-opened hydraulic pressure solenoid directional control valve, and is connected to operating points through the normally-closed hydraulic pressure solenoid directional control valve. The flow rate adjustable and inching type measuring distributor has the advantages of precise measurement for high-pressure irrigation and store, safety and energy saving for low-pressure push and deliver, large inching output control range, large liquid viscous scope of application, ability to transport chemicals, slurry and corrosive liquid, ability to be combined with general metering pump through proper connection and treatment, and ability to solve the large instant fluid measure output (that is the inching and measuring output) problem which can not solved by the prior metering pump.

Description

technical field [0001] The invention relates to a fluid metering and dosing device, in particular to a metering distributor. Background technique [0002] As equipment for fluid metering and dosing, metering distributors are used in various fields including machinery manufacturing, mining, tunneling, pharmaceutical and petrochemical industries, and are responsible for strong corrosion, toxicity, high viscosity and high pressure in the process. Metering addition tasks for media. With the general improvement of people's requirements for production process indicators and automation, as the final actuator of the fluid dosage addition link, the controllability and flexibility requirements of the metering dispenser under certain precision conditions have become increasingly important. [0003] Metering distributors can usually be divided into two categories, one is to use electronic meters to control the flow, and the other is to use traditional volumetric reciprocating metering ...
