Abstract

The utility model discloses a pressure gauge. The pressure gauge is mainly composed of a gauge housing, a fluid input part, a Barton tube, a pointer, a core, an indication panel and a transparent face shield. The fluid input part is formed by splicing an installation seat arranged on the inner bottom face of the gauge housing and a joint which can be fixedly arranged on the installation seat. Fluid conveying pipelines which can convey fluids to the inner side of the Barton tube are arranged inside the installation seat and the joint. The Barton tube is fixedly arranged on the joint. By adopting the above-mentioned structure and making the fluid input part formed by splicing the installation seat and the joint, the pressure gauge can have the installation seat and the joint respectively cast by plastic and copper materials. Parts of copper materials can be saved. The copper consumption is reduced. Meanwhile, the production cost of the pressure gauge is lowered.

Description

Tensimeter

Technical field

The utility model relates to a kind of tensimeter, belongs to measurement and control instrument technical field.

Background technology

At present, tensimeter is mainly used to the pressure of the fluids such as measurement gas or liquid.Tensimeter is generally comprised of watchcase, fluid input part, Ba Dunguan, pointer, indication panel, movement and transparent face mask, described fluid input part is arranged on the interior table bottom surface of watchcase, pause one end of pipe of described bar is fixedly mounted on fluid input part, the pause other end of pipe of described bar is connecting movement, and described movement is connecting pointer.When above-mentioned tensimeter is used for measuring the pressure of fluid, Ba Dun pipe is subject to the impact of hydrodynamic pressure, there is deformation in one end that Ba Dun pipe is connected with movement, thereby drive movement motion, movement drives pointer to rotate, thereby at indication panel by the pressure representative of fluid out, existing manometric fluid input part is generally all to adopt copper metal to mould, and then be arranged on watchcase, because the price of copper metal is relatively costly, thereby increased manometric production cost, be unfavorable for improving the competitiveness of society of enterprise; Also can consume in addition more copper resource, order lacks more to global copper resource.

Utility model content

In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, both can saving copper resource, can reduce again the tensimeter of manometric production cost.

The utility model for the technical scheme that solves its technical matters and adopt is:

Tensimeter, mainly by watchcase, fluid input part, Ba Dunguan, pointer, movement, indication panel and transparent face mask, formed, described fluid input part forms with the connector splicing that can be fixedly mounted on mount pad by being arranged on the mount pad of showing on bottom surface in watchcase, the inside of described mount pad and connector is provided with and can transports fluid into a bar inner fluid-transporting tubing of pipe, and the described bar pipe that pauses is fixedly mounted on connector.

In order to make the production and processing of mount pad convenient, described mount pad and base are injection moulding integrated molding.

For the location and installation that makes connector simple and fast more, on described mount pad, be provided with the locating convex block of being convenient to connector location and installation.

For connector can be fixedly mounted on mount pad more, on described mount pad, be provided with one or above, be convenient to connector and be fixedly mounted in the bolt hole on it.

The beneficial effects of the utility model are: because the utility model adopts above-mentioned structure, fluid input part is comprised of mount pad and connector splicing, therefore mount pad and connector can adopt respectively plastics and casting in bronze to make, thereby can save a part of copper product, both can reduce the consumption of copper, can reduce manometric production cost again, not only contribute to alleviate the pressure of copper resource scarcity, can strengthen again the competitiveness of society of enterprise.

Embodiment

Referring to figs. 1 through Fig. 5, tensimeter, mainly by watchcase 1, fluid input part 2, Ba Dun pipe 3, pointer 4, movement 5, indication panel 6 and transparent face mask 7 form, described fluid input part 2 is comprised of connector 21 splicings that are arranged on the mount pad 20 on the interior table of watchcase 1 bottom surface and can be fixedly mounted on mount pad 20, above-mentioned mount pad 20 is preferentially manufactured gained by injection moulding integrated molding with base 1, the described preferential employing copper product of connector 21 manufacture, can certainly adopt plastics or other materials to make, the inside of described mount pad 20 and connector 21 is provided with the fluid-transporting tubing 22 that can transport fluid into bar pipe 3 inside, described bar pipe 3 the one end of pausing is fixedly mounted on connector 21, the above-mentioned joint that is separately positioned on the fluid-transporting tubing 22 of mount pad 20 and connector 21 inside is provided with O-ring seal 202, prevent that fluid from leaking from the joint of mount pad 20 and connector 21, described O-ring seal 202 is rubber ring or silica gel ring.

Further, on described mount pad 20, be provided with the locating convex block 200 of being convenient to connector 21 location and installation, the quantity of described locating convex block 200 is two, coordinate while installing, two locating convex blocks 200 lay respectively at the both sides of connector 21, between above-mentioned locating convex block 200 and mount pad 20, be injection moulding integrated molding, facilitate production and processing.

Further again, on described mount pad 20, be provided with one or above, be convenient to connector 21 and be fixedly mounted in the bolt hole 201 on it, here, the number of described bolt hole 201 is preferentially set to two, during installation, by adopting two pieces of bolts respectively through after two bolt holes 201, then be connected to a fixed with connector 21, thereby connector 21 is fixedly mounted on mount pad 20.

The foregoing is only preferential embodiment of the present utility model, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
