Abstract
The utility model provides a cylinder-type pressure meter including a pipeline pressure meter isolation diaphragm. The pipeline pressure meter isolation diaphragm is a thin-wall cylinder. Oval sunken faces are distributed in the outer wall of the cylinder. The sunken faces are distributed in a manner of taking the axis of the cylinder as the circle center. Long axes of the sunken faces are in parallel with the axis of the thin-wall cylinder. Sunken volume in the circle centers of the oval sunken faces is the maximum and decreases gradually on the periphery. The pipeline pressure meter isolation diaphragm is a laser welding isolation diaphragm connected with a process pipeline directly. The cylinder-type pressure meter can realize pressure display directly and can display electrified contact switch signal output. Omni-bearing fluid pressure measurement can be realized and temperature and pressure measurement can be realized at the same time. And the cylinder-type pressure meter is comparatively high in pipeline fluid pressure detection precision and is high temperature resisting and high pressure resisting. The cylinder-type diaphragm has no protruded corners and no measurement dead zones. The diaphragm does not contract transversely. And since the outer wall of the diaphragm is welded in a weld joint manner when the outer wall is in a flat state, no special welding tools are needed and a problem of solder loading is solved. The oval sunk faces formed through dilatation have comparatively good flexibility and flexibility and do not break in a using process.
Description
Technical field
The utility model relates to a kind of a kind of electronics and IT products that are mainly used in the safety technological guard field, relates in particular to a kind of drum type brake tensimeter.
Background technology
Tensimeter in the past adopts the corrugated isolation diaphragm usually, as Fig. 3, shown in Fig. 4, the corrugated projection 2 on thin cylinder 1 and cylinder 1 outer wall, consists of.Corrugated projection 2 becomes circle distribution along the center of circle of cylinder 1, and along cylinder 1 outer wall extend axially.Isolation diaphragm adopts mould molding, utilizes undulatory rigid displacement, realizes the transmission of gas or fluid pressure.The subject matter existed is:
(1) isolation diaphragm is by being welded to its function of performance on the isolated body miscellaneous part; the easily fracture due to cylinder 1 wall thickness too thin (generally at 0.08mm-0.1mm) when welding; and, due to the corrugated projection 2 on the isolation diaphragm outer wall, welding needs special tooling;
(2) in the isolation diaphragm use procedure, also easy fracture after cylinder 1 pressurized, cause isolation diaphragm to scrap, and often changes, and use cost is higher;
(3) corrugated projection 2 belongs to rigid displacement, and insufficient sensitivity is transmitted in displacement.
In view of above several problems, a kind of new manometric invention of a kind of drum type brake effective, that security performance is high is imperative.
The utility model content
The technical problems to be solved in the utility model is: the corrugated isolation diaphragm that tensimeter adopts in the past and the various defective problems brought.
In order to achieve the above object, the utility model provides a kind of drum type brake tensimeter, it comprises: pipe pressure gauge isolating diaphragm, it is characterized in that: described pipe pressure gauge isolating diaphragm is a thin cylinder, be distributed with oval-shaped concave face on described cylinder outer wall, described concave face be take the cylinder axle center and is become circle distribution as the center of circle, and the major axis of this oval depressions face is parallel with the axis of thin cylinder, described concave face in the amount of recess maximum of oval circle centre position gradually to the oval rim transition; Described pipe pressure gauge isolating diaphragm is that the laser bonding barrier film directly is connected with the process pipeline.
Oval depressions face on described cylinder outer wall is four.
Described drum type brake tensimeter also comprises: the display panel that direct pressure shows shows the output of band electrical contact switch signal.
Described pipe pressure gauge isolating diaphragm can transversal shrinkage.
The beneficial effects of the utility model are: but the demonstration of the utility model drum type brake tensimeter direct pressure can be with the output of electrical contact switch signal; Omnibearing hydrodynamic pressure is measured, and can measure temperature and pressure simultaneously; More high-precision pipeline fluid pressure detection, high temperature resistant, high pressure resistant; The drum type brake diaphragm, without coign, do not have blind area, and diaphragm can transversal shrinkage.Can directly with the process pipeline, be connected! And the pipe pressure gauge isolating diaphragm of this structure is adding man-hour, first will isolate matrix and make thin cylinder, again the thin cylinder outer wall is welded on the isolated body miscellaneous part, after welding is good, with certain air pressure, carries out swollen type, self-assembling formation pipe pressure gauge isolating diaphragm described in the utility model.Because outer wall is the employing weld seam welding under smooth state, do not need special-purpose fiery tool, solved and filled a fiery difficult problem; The oval depressions face that swollen type forms, have flexible sensitivity preferably higher, in use procedure, also can not rupture.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
The utility model provides a kind of drum type brake tensimeter, and it comprises: pipe pressure gauge isolating diaphragm, pipe pressure gauge isolating diaphragm as depicted in figs. 1 and 2, be a thin cylinder 1.Be distributed with oval-shaped concave face 2 on cylinder 1 outer wall, concave face 2 be take cylinder 1 axle center as center of circle one-tenth circle distribution, the major axis of oval depressions face 2 is parallel with the axis of thin cylinder 1, concave face 2 in the amount of recess maximum of oval circle centre position gradually to the oval rim transition until be zero.Concave face 2 also correspondingly caves inward on cylinder 1 inwall, makes cylinder 1 identical at the wall thickness of arbitrfary point.Oval depressions face 2 on cylinder 1 outer wall can be two, four or more.
The moulding of the concave face 2 of the pipe pressure gauge isolating diaphragm of this structure; by the swollen type of certain air pressure, to form after cylinder 1 is welded on the isolated body miscellaneous part; make cylinder 1 wall thickness even, oval-shaped concave face 2 caves at most at oval circle centre position, gradually to cylinder 2 outer wall transition; Pipe pressure gauge isolating diaphragm is the welding of carrying out under smooth state, does not need special-purpose fiery tool, has solved and has filled a fiery difficult problem; The oval depressions face that swollen type forms, have flexibility preferably, and it is higher that sensitivity is transmitted in displacement, in use procedure, also can not rupture.
Described pipe pressure gauge isolating diaphragm is that the laser bonding barrier film directly is connected with the process pipeline.Contact medium is partly the diaphragm body volume of stainless steel or special substance, optimization; Described drum type brake tensimeter also comprises: the display panel that direct pressure shows shows the output of band electrical contact switch signal.Described pipe pressure gauge isolating diaphragm can transversal shrinkage.
The description of application above preferred embodiment makes those skilled in the art can manufacture or use the utility model.The various modifications of these embodiment are apparent for a person skilled in the art, and the General Principle of definition can be applied in other embodiment and do not deviate from spirit or scope of the present utility model here.Therefore, the utility model is not limited to shown here embodiment, and will meet the most wide in range scope consistent with the principle disclosed and novel feature here.
