Problems solved by technology

[0006] However, with the continuous increase in the demand for large-flow measurement in water supply, hydraulic, electric power and other industries, considering the conditions of large-flow liquid inflow, most of the containers used in this type of standard verification device are closed-type capped structures. The top cover of the container interferes, and it takes time and effort to remove the additional load (container) during the verification and inspection process of the weighing instrument. At the same time, the lifting process is likely to cause physical damage to the weighing instrument, which poses a safety hazard

Embodiment Construction

[0039] like figure 1 , figure 2 , image 3 and Figure 4 As shown, an anti-spill flow standard device for large-flow liquid inlet, the flow standard device includes a scale (electronic scale) 1, a container 2, a top cover 3, an anti-spill device 4, a stud 5, a water divider 6 and commutator 7.

[0040] The top cover 3 is provided with a through hole, and 6 protrusions are evenly distributed in the circumferential direction around the through hole. A pair of lifting lugs are arranged on the top cover 3 to facilitate overall hoisting. The top cover 3 and the container 2 are fixedly connected by 16 sets of bolt fasteners in the circumferential direction, forming a unified whole.

[0041] The anti-overflow device 4 is a hollow cylinder, and three "J"-shaped installation grooves 45 are opened on the top of the hollow cylinder in the circumferential direction, and three groups of wing plates 43 are uniformly distributed on the side wall of the hollow cylinder in the circumfere...

Abstract

The invention relates to an anti-spilling flow rate standard device and a calibration method applicable to large flow rate liquid entrance. The flow rate standard device is used mainly aiming at the large flow rate fluid entrance; and the large flow rate generally exceeds 15 kg/s. The invention especially relates to anti-spilling design of a water distributor of the standard device applicable to calibration and metering a liquid flow rate, wherein the anti-spilling water distributor is connected to an open type diverter and a container; through two working states of "suspension" and "sedimentation", different demands of the flow rate standard device under two working states including flow rate calibration and weighing appliance checking calibration can be satisfied; the problem about liquid spilling of a traditional water distributor is solved; and reliability and accuracy of flow rate calibration work are ensured.

Description

technical field [0001] The present invention relates to an anti-spill flow standard device and verification method for large-flow liquid inflow. The use of the flow standard device is mainly aimed at the situation of large-flow liquid inflow. The large flow generally refers to a flow rate of more than 15kg / s , especially relates to an anti-overflow design of a standard device for liquid flow verification and measurement. The anti-overflow distributor is connected to an open commutator and a container, and is guaranteed by two working states of "suspension" and "settling". The flow standard device has different requirements in the two working states of flow calibration verification and weighing instrument inspection verification, which solves the problem of liquid overflow in traditional water separators and ensures the reliability and accuracy of flow verification work. Background technique [0002] With the development of industrial production automation and pipeline, vario...
