Abstract
The utility model discloses a differential pressure test device which comprises a base arranged on a chassis, a housing, a differential pressure core body, connecting bolts and joint nuts, wherein the differential pressure core body is packaged in the housing, and external pressure is transmitted to the differential pressure core body through the joint nuts at two pressure inlet head ends and the connecting bolts to form an all-solid-state structure for pressure measurement, thus realizing the measurement of pressure difference between the two ends. The main advantages of the differential pressure test device are as follows: customers can install the differential pressure test device conveniently, the differential pressure test device can be installed in the way of being in butt joint with a transmitter, and the differential pressure test device is more stable after being installed.
Description
Technical field
The utility model relates to a kind of differential pressure proving installation.
Background technology
KH0099; KH0099B is a core component of making pressure transducer and pressure unit; its all parts all adopt the stainless steel all-welded structure; anticorrosion; enclose inside is the differential pressure core body independently; so not only can measure differential pressure value accurately, also can protect core body to be without prejudice, make things convenient for the client to install.
But inconvenient client of existing KH0099 core body and transmitter are installed, and unstable after installing.
The utility model content
The utility model purpose is to provide a kind of differential pressure proving installation at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The utility model differential pressure proving installation, comprise the base, housing, differential pressure core body, coupling bolt and the collar nut that are arranged on the chassis, wherein the differential pressure core body is encapsulated in the housing, two collar nuts are arranged at two entrance pressure head ends respectively, collar nut is connected with the differential pressure core body by coupling bolt, impressed pressure is delivered to the tonometric structure of whole solid state of formation on the differential pressure core body by collar nut, the coupling bolt of two entrance pressure head ends successively, realizes measuring the pressure differential at entrance pressure head two ends.
Described differential pressure core body comprises positive pressure side and the negative pressure end that is symmetricly set in the compensating plate two ends, and O type circle is set respectively on described positive pressure side and the negative pressure end, and described compensating plate is drawn by lead.
Major advantage of the present utility model makes things convenient for the client to install exactly, and installation is docked in realization with transmitter, and more stable after installing.
