Abstract
The utility model relates to a pressure meter. In the utility model, a pressure sensing mechanism adopts a plunger piston and a helical compressing spring, the pressure of a pipeline acts on the helical compressing spring by the plunger piston, the compression amount of a spring and the pressure in the pipeline are in direct proportion, pressure value is indicated by an indicating ring with simultaneous displacement. The utility model has the advantages of simple structure, compact body, easy fabrication, low cost and high durability and is convenient for users for observing pressure at different orientations, and the utility model can be used for agriculture departments, environmental protection departments, etc.
Description
The utility model relates to a kind of tensimeter, is used for detecting the pressure of pipeline fluid.
Existing tensimeter is of a great variety, and as manometric pressure sensing part, flexible member wherein has corrugated tube, ripple sylphon and rectangular tube etc.Above-mentioned tensimeter has higher sensitivity and measuring accuracy, but processing technology complexity and cost are higher, it is just very unsuitable to be used on some equipment, for example agricultural goes up spraying machine that uses and the washer that uses everywhere, claimed structure is simple, tensimeter with low cost is to reduce occupying space and cost.
The purpose of this utility model provides a kind of tensimeter simple in structure, easily manufactured and cheap.
Technical solution of the present utility model is, a kind of tensimeter, and it is made up of pressure sensing and indicating mechanism, and its pressure sensing partly adopts plunger and spiral compression spring.Indicating mechanism comprises indicating ring and pressure scale.Plunger is passed to spiral compression spring with pressure, and the decrement of spring is directly proportional with pressure, and force value is indicated on scale by indicating ring.
Below in conjunction with embodiment shown in the drawings, the utility model will be further described.
Accompanying drawing is the semisectional view of present embodiment.
Present embodiment is made up of matrix (1), plunger (2), seal (3), spring cup (4), indicating ring (5), spiral compression spring (6) and case (7).The tapered tread and the pressure pipeline of pedestal (1) front end join, and its end thread is connected with case (7).The plunger (2) that has seal (3) is contained in the inner chamber of matrix (1), and plunger (2) leans on spring cup (4), is provided with showy indicating ring (5) in the groove in the middle of the spring cup (4).Spiral compression spring (6) one ends are enclosed within on the spring cup (4), the other end withstands on the case (7), case (7) is carved with pressure scale (8) on aspect three, can in any direction observe indicating ring (5) and go up the position that stops at pressure scale (8), so that carry out reading.
After tensimeter was pressed into pressure pipeline by tapered tread, pressure fluid entered inner chamber by the aperture of matrix (1) front end, promoted plunger (2) and pressed spring cup (4), and spiral compression spring (6) is made axial compression, and the interior pressure of its decrement and pipeline is directly proportional.Indicating ring (5) is also done synchronous displacement, so just indicate force value.
The utlity model has simple in structure, the body compactness, be convenient to make and inexpensive The advantage such as durable has broad application prospects in agricultural and environmental protection industry (epi).
Claims (3)
1, a kind of tensimeter with pressure sensing and indicating mechanism is characterized in that pressure sensing mechanism adopts plunger (2) and spiral compression spring (6).
2, tensimeter according to claim 1 is characterized in that being provided with indicating ring (5) in the groove of spring cup (4).
3, tensimeter according to claim 1 and 2 is characterized in that three aspects of case (7) are carved with pressure scale (8).
