Abstract

The utility model relates to a pressure gauge which is used for measuring the liquid pressure of a synthetic hydraulic support in coal mines. The utility model is mainly composed of a housing, a joint, a spring, an adjusting sleeve, a spacing block, etc. The utility model is characterized in that a scale rod is arranged in the housing, the middle part of the scale rod is provided with a big circle which is used for positioning and guiding, the lower end of the scale rod has scales used for reading pressure values and the housing and the joint are respectively manufactured and connected into a whole. The utility model has the advantages of simple structure, reliable work and stable performance, therefore the utility model is a pressure gauge which can accurately measure the liquid pressure of a support.

Description

The utility model belongs to the instrument that is used to measure the comprehensive mining hydraulic bracket fluid pressure in the colliery.
Many working pressures of pressure table pressure measurement of measuring fully mechanized mining supporter liquid in the colliery at present, though directly perceived, very easily damage; Use spring pressure ga(u)ge, because unreasonable structure makes unstable properties, precision is low.
The purpose of this utility model is to design a kind of novel simple in structure, stable performance, and reliable operation, not fragile, can accurately measure the pressure gauge of poppet pressure.
The utility model by shell (4), be contained in spring (6) in joint (1) on the shell (4), the shell (4), adjust cover (9), limited block (7) is formed, it is characterized in that in shell (4) and joint (1), scale bar (3) being housed.
The utility model has the advantages that simple in structure, reliable operation, stable performance, the precision height, it is fragile to have solved the gauge outfit pressure gauge, problems such as other gauge performance instabilities.
Accompanying drawing is the utility model structural representation, (1)-joint among the figure, (2), (5), (8)-O RunddichtringO; (3)-and the scale bar, (4)-shell, (6)-spring, (7)-limited block, (9)-adjust and overlap.For ease of processing, joint (1) and shell (4) are divided into two processing respectively, then be assembled into one, O RunddichtringO (2), (5) are housed on the joint (1), scale bar (3) is loaded in the shell (4), and the part of scale bar in joint (1) plays the pressure measurement piston action, and the big circular portion in scale bar middle part plays the guide and limit effect in shell (4), big circular portion cylindrical section be arcuation to reduce friction, the scale bar has scale to be used for reading on (3).Spring (6) is housed in the shell (4) and is enclosed within on the scale bar (3), be positioned between scale bar middle part great circle and the limited block (7), one end is on the great circle of scale bar middle part, and the other end is connected on the limited block (7), and the decrement of spring (6) is not more than 1/3rd of length overall.Limited block (7) adopts screw thread to be connected with shell (4) with adjustment cover (9), adjusts cover (9) and plays the adjustment pressure reading.During pressure measurement, joint (1) is communicated with the hydraulic support high pressure chest, fluid pressure promotes scale bar (3) motion, make length of spring compressed, scale bar (3) is protruding, and overhang and pressure are directly proportional, pressure gauge is pressure value through demarcating by the direct reading of scale bar.Scale bar (3) collection piston, guiding, spacing, scale are in one.

Claims (4)

1, a kind of poppet pressure meter that is used for colliery measurement comprehensive mining hydraulic bracket fluid pressure, by shell (4), be contained in spring (6) in joint (1) on the shell (4), the shell (4), adjust cover (9), limited block (7) is formed, it is characterized in that in shell (4) and joint (1), scale bar (3) being housed.
2, pressure gauge according to claim 1 is characterized in that scale bar (3) middle part is the great circle shape, and its end face is circular-arc, plays spacing guide effect.
3, pressure gauge according to claim 1 and 2, it is characterized in that in shell (4), being equipped with spring (6), and be enclosed within on the scale bar (3), spring one end is contained on the great circle of scale bar (3) middle part, the other end is connected on the limited block (7), and the decrement of spring (6) is not more than 1/3rd of length overall.
4, pressure gauge according to claim 1 is characterized in that adjusting cover (9) and is loaded on the shell (4), works to adjust pressure reading.
