Abstract
The utility model discloses a repeater box of a vortex precession flowmeter, which comprises a front cover (1) and a box body (7). Plate glass (2), a gasket (3), a press plate (4), a liquid-crystal display panel (5) and an intelligent plate (6) are sequentially fixedly installed in the front cover (1) and the box body (7) through a screw (12). A plug screw (10) and a gland (11) are installed on the box body (7) through a rubber pad and an O-ring (9). The utility model is characterized in that a male locating slot (13) and a female locating slot (14) are respectively arranged on the contact sealing surfaces of the front cover (1) and the box body (7). The male locating slot (13) is matched with the female locating slot (14). The utility model has the advantages that the structure is simple, the joint is firm and reliable and the explosion resistance performance of the hard seal is high.
Description
Technical field
The utility model relates to instrument and meter, is specifically related to the repeater box of vortex precession flowmeter.
Background technology
The principle and the structure of the repeater box that flow instrument adopts are varied, are integrated and divide body structure with the branch that is connected of flowmeter.At present, the flowmeter repeater box of integrated structure design mostly adopts side seal, improves sealing property by " O " type circle and resilient rubbber cushion, but can not satisfy the uniform technical requirement of flame proof, has also reduced explosion-proof performance.
Summary of the invention
The purpose of this utility model is: a kind of vortex precession flowmeter repeater box is provided, and this repeater box adopts rigid sealing, effectively guarantees the explosion-proof performance of repeater box.
The technical solution of this Practical Performance is: this repeater box comprises protecgulum and box body, in protecgulum and box body, fixedly mount sheet glass, pad, pressing plate, LCD panel and intelligent plate successively by screw, on box body, plug screw and gland are installed, are it is characterized in that: on protecgulum and sealing surface that box body contacts, establish the male and female locating slot that cooperatively interacts respectively by rubber blanket O type circle.
During assembling, protecgulum and box body pass through the male and female locating slot through screw retention; During use, the input end and the vortex precession flowmeter of the lid part of damming is connected, on demand output signal line is connected with lead-out terminal by electric interfaces.
The utility model is simple in structure, can not misplace in conjunction with solid and reliable, and rigid sealing explosion-proof performance is strong.
