Abstract
The utility model relates to a multi-function pressure indicator, which is used for a mine support device and is an improvement on the prior pressure indicator. The utility model comprises a casing, a joint, a daily indicating rod, and a reset spring, characterized in that the daily indicating rod is sheathed with a maximum pressure indicating rod; instant working fluid pressure observed (daily detecting) and the maximum pressure (circulating detection) before observation during work can be detected. The utility model has the advantages of simple structure, reliable work, and convenient operation.
Description
The utility model belongs to the fluid pressure detecting instrument, is mainly used in the hydraulic support that mine support is used, and the pressure detecting of hydraulic prop is the improvement to existing Hydraulic Pressure Indicator.
Present mine support equipment hydraulic support, generally adopt a kind of mechanical compression indicator during detected pressures such as hydraulic prop, this pressure indicator mainly is made up of main parts size such as shell, indicating arm, spring, joints, its indicated pressure detecting is to change with the actual pressure value of support (pillar), therefore the instant pressure in the time of can only demonstrating the testing staff and detect, can not show the maximum pressure that is carried in hydraulic support (pillar) cycle period, use extremely inconvenient.
The utility model improves existing machinery formula Hydraulic Pressure Indicator, and purpose provides a kind of routine work pressure that promptly shows, shows the full-service fluid pressure indicator of maximum working pressure (MWP) in the cycle period again.
Now in conjunction with the accompanying drawings the technical solution of the utility model and enforcement legend are described:
Legend: 1, brake hoop; 2, shell; 3, spring; 4, maximum pressure indicating arm; 5, daily pressure indicating arm; 6, spring base; 7, clamp nut; 8, anti-extrusion ring; 9, O RunddichtringO; 10, joint; 11, plunger.
Concrete scheme is that brake hoop 1 and spring 3 are housed in (1), the shell 2, and spring 3 one ends withstand on cover top portion, and the other end withstands on the spring base 6, and skewers are gone into hollow indicating arm 4 in the spring 3, inserts daily pressure indicating arm 5 in spring base 6 and indicating arm 4 hollow; (2), load onto plunger 11 in the mesopore of joint 10, put anti-extrusion ring 8 and O RunddichtringO 9 on the plunger, and anti-extrusion ring 8 and O type circle 9 are compressed with clamp nut 7; (3), joint 10 is threaded on the shell 2.
When work, the joint skewer of this indicator is gone in the special-purpose side opening of tested support and to fix with clamp, moved in shell by measuring pressure effect lower plunger 11, also simultaneously indicating arm 4 and 5 is released from the hole on housing 2 tops by spring abutment 6 compression springs 3, when support (pillar) pressure reduces, under spring 3 effects, make daily pressure indicating arm 5 return certain distance, and maximum pressure indicating arm 4 is fixed on the origin-location under the effect of brake hoop by spring base 6.By the ring-type graduation mark on indicating arm 4 and 5, can read operating pressure maximum in the cycle of detected support (pillar) and instant operating pressure, detection finishes, and pushes the position of indicating arm 4 tops to spring 6 with hand, recover instant pressure state, treat to detect usefulness next time.
The utility model has the advantages that maximum working pressure (MWP) and daily operating pressure in the cycle of measuring simultaneously support (pillar), for the mine more reliable detection support (pillar) operating pressure a kind of simple and reliable pressure indicator is provided.
Claims (1)
1, a kind of multi-functional pressure indicator that is used for mine prop (pillar) tracer liquid pressure, its structure is: brake hoop 1 and spring 3 are housed in (1), the shell 2, insert daily indicating arm 5 in the spring 3; (2), shell 2 threaded one ends connect by top connection 10, and plunger 11 are housed in the mesopore of joint 10, put anti-extrusion ring 8 and O RunddichtringO 9 on the plunger 11, and nut 7 compress; (3), also comprise its characteristic: be with on the daily indicating arm 5 and be used to the hollow indicating arm 4 and the spring base 6 of indicating maximum pressure to use.
