Abstract
The utility model relates to a pressure tester in a flow-partitioning pressure-guiding type, which is used for the pressure test of an on-line process system. The inner cavity of a screw plug at the pressure-guiding end of the utility model is provided with a flexible rubber sleeve which partition a central through hole which is connected with the pressure-testing end of the utility model; a pressure partitioning pad is arranged between the flexible rubber sleeve and the bottom surface of the inner cavity of the screw plug. The rubber sleeve is compacted by a pressing plug; a connector at the pressure testing is connected with the screw plug, and is sealed by a copper pad; the other end of the connector is connector with a plunger rod which is connected with a plunger sleeve with adjustable dept by outer screw thread; the other end of the plunger rod is connected with a pressure meter. The utility model has the advantages of convenient installation and maintenance, and portability and is suitable for the operating conditions in fields and open air; the utility model can accurately test pressure, and a pressure point has no phenomenon of fluid outleakage.
Description
The utility model relates to a kind of stopping pressure-guiding pressure type manograph that is used for the process system pressure test.
Industry such as oil, chemical industry has pair requirement of process system pressure test, the environmental working condition of online pressure tap is complicated, high temperature, high and cold is arranged, indoor, outdoor, the branch outside plant area, the factory, management has proposed higher requirement to manometric technique, shortcomings the such as at present pressure tester of using is because of there being the pressure measurement error big, and anti-tamper, lost circulation prevention, theftproof performance are relatively poor, suitable inadequately in many occasions.
The purpose of this utility model provides a kind of stopping pressure-guiding pressure type manograph, and is convenient for installation and maintenance, adapts to open-air, outdoor operating mode, can measure pressure more exactly, and pressure tap does not have the fluid phenomenon that leaks outside, and is easy to carry.
The purpose of this utility model is achieved in that
A kind of stopping pressure-guiding pressure type manograph that is used for online process system pressure test is characterized in that: it is made of pilot end and pressure measurement end two parts;
The main body of pilot end is a plug, and its inner chamber is equipped with a flexible gum cover and the central through hole that will connect the pressure measurement end cuts off, between the inner chamber bottom surface of flexible gum cover and plug, be placed be used for dispersive pressure every pressure pad.This gum cover is by the stifled compacting sealing of porose pressure;
The joint of pressure measurement end is connected with the screw of plug and with copper packing sealing, joint hold the joint pin stopper rod in addition, this plunger rod becomes being connected of the scalable degree of depth with external thread and plunger bushing, this plunger is end connection tensimeter in addition;
The center pit of described plug is through the center pit of joint, and the center pit of plunger rod is communicated with tensimeter.
End at the plunger rod of described pressure measurement end is equipped with the fluid sealant bowl.
The utility model has following actively useful effect:
But the utility model adopts the elastomeric material of the corrosion-resistant oil resistant of buffer fluid to make flexible pilot element, this pilot component inner surface contact process fluid, outside surface contact pressure measuring tie-in runner, surfaces externally and internally periphery compacting sealing; Utilize plunger to pay that volume-variation can improve or the effect of step-down power design manograph.When dwindling volume behind the full of liquid in plunger is paid, cavity pressure raises, through being communicated with the outside surface side that runner conducts to flexible pilot element, when pilot part external pressure less than interior pressure, flexible pilot component shape is constant, and plunger is paid internal pressure and continued to raise, until inside and outside pressing weighing apparatus pilot deformed element.Pay interior pressure variation with tensimeter detection plunger and just can record online operation pressure value indirectly.
Technological merit of the present utility model is: use flexible pilot element that internal flow and external environment condition are separated, not be used in the pressure tap mounted valve; Fluid in the process system can not flow out when operate as normal; The pressure guiding device exposed parts seldom is convenient to management; Manograph with after can unload down, multi-uses etc. have convenient for installation and maintenancely, adapt to open-air, outdoor operating mode, can measure pressure more exactly, pressure tap does not have fluid leak outside phenomenon and portable advantage.
Accompanying drawing is the utility model stopping pressure-guiding pressure type manograph assembly general assembly sectional view.
Below in conjunction with accompanying drawing structure of the present utility model and principle of work are described in further details: the stopping pressure-guiding pressure type manograph is by constituting every conductance pressure side and pressure measurement end two parts, and the pilot end is installed on online process system, and the pressure measurement end is carried by operating personnel., plug 2, pressure measurement gum cover 3 stifled 1 by pressing, constitute the online technology pressure tap position that is installed on every pressure pad 4 and copper packing 5 every the conductance pressure side.Its pressure conduction pattern is to utilize flexible gum cover 3 distortion to realize, and don't makes the fluid of gum cover 3 inner chambers flow out when not pressure measurement, has removed the pressure measurement by-pass valve control from.The inner chamber contact of pilot end gum cover 3 every pressure pad 4 dispersive pressures, prevents that gum cover from puncturing by pressing fluid that blocks up the importing of 1 center pit and the pressure that bears fluid.
Described flexible gum cover 3 thinner thicknesses, its periphery can not flow out the fluid of gum cover 3 inner chambers by pressing stifled 1 to be compacted on the shoulder of plug 2 inner chambers, punctures under differential pressure action for avoiding gum cover 3, between gum cover 3 bottom surfaces and plug 2 inner chamber bottom surfaces, put one, so that dispersive pressure every pressure pad 4.
The pressure measurement end is made of joint 6, plunger rod 7, glue bowl 8, jump ring 9, plunger bushing 10 and tensimeter 11.
Plunger rod 7 central punch of dress in the pressure measurement end can be conducted oil stream, and equipped glue bowl 8 in plunger rod end and plunger bushing 10, tensimeter 11 constitute the chamber of sealing, and this cavity volume is variable, can give pressurized with fluid, can also appropriateness vacuumize.
A silk hole of during pressure measurement the plug 2 of the joint 6 of pressure measurement end and pilot end being exposed is connected and appropriateness fastening, guarantee joint 6 end compacting copper packings 5 and seal.Plunger bushing 10 turns clockwise, the plunger cavity volume that is made of plunger rod 7 end glue bowls 8, plunger bushing 10 and tensimeter 11 dwindles, be loaded on the central duct of fluid by plunger rod 7 and joint 6 in this plunger cavity flow on the plug 2 equipped every pressure pad 4, and by every the slit flow of pressure pad 4 bottom to gum cover 3.Continue column spinner plug sleeve 10, the plunger cavity oil liquid pressure rises, gauge hand is along with the dextrorotation of plunger bushing 10 transfers constantly to rise, when the plunger cavity internal pressure is consistent with gum cover 3 chamber pressures, the Rotational Cylindrical plug sleeve 10 again, tensimeter 11 pointers no longer rise, and gum cover 3 bottom surfaces cave inward under the effect of fluid, abdicate volume.Force value shown in the stable back of tensimeter 11 pointers is the hydrodynamic pressure of process point.
After measuring pressure is finished, be rotated counterclockwise plunger bushing 10 to list index and fall zero, releasable joint 6 is connected with plug 2, and the pressure measurement end is taken back standby by operating personnel conveniently.
