Description
Technical field
The utility model relates to the hydraulic machinery technical field, and particularly in dismounting tensimeter process, can reach fast, put pressure safely, and in installation process, can adjust the joint of tensimeter direction arbitrarily, be a kind of multi-functional pressure meter connector.
Background technology
In the oil gas field production equipment, the tensimeter operation valve of some process equipments and pipeline does not have emptying, can't carry out first pressure release when verification, replacing tensimeter and dismantle manometric operation again.At present; Directly dismantle tensimeter after having only closing presure table by-pass valve control in the process of dismounting, limit sloshing pressure table is slowly dismantled on the limit, carries out pressure release from the screwed connection of meter connector; Tensimeter flies out to exist pressure to let out not to the utmost, causes personal injury accidents and the potential safety hazard of device damage.If all tensimeter operation valves are changed the valve that is installed as band emptying: the first, cause installation cost to increase; The second, because in the production of oil gas field; Equipment component is in long-term running status, just can carry out if the tensimeter operation valve is changed when stopping production or ME such as having only.If change by force, will impact production, secondly by containing impurity in the tested media such as gas-liquid, the tensimeter tracting pressuring hole is stopped up, manometric serviceable life is shortened in the inaccurate or tensimeter damage of build-up of pressure table measured value.At last, when tensimeter was installed, dial side should be easy to observe, but existing pressure tapping makes manometric direction be not easy adjustment, causes reading of pressure tabular value and is not easy to accomplish sight alignment in the process, and the value of reading is accurate.
The utility model content
The purpose of the utility model is: a kind of multi-functional pressure meter connector is provided; To the phenomenon that can't put pressure that the tensimeter tracting pressuring hole stops up, part is changed existence in the tensimeter operation; Through in pressure tapping, installing filter screen additional and putting the mechanism of pressure; For operation provides safer, reliable production environment, with stop tensimeter in unloading process because of can't pressure release security incident taking place or change the tensimeter operation valve by force production is impacted, prolong manometric serviceable life.
The technical scheme that the utility model adopts is: the multi-functional pressure meter connector comprises meter connector, connector, housing, valve ball, ball seat, rubber cushion, push rod, gland, pressure cap, draining connector, filter screen and compression spring.Housing is a square steel threeway, and housing has two straight-through ports and a vertical port, on the outer wall of straight-through port, external thread is arranged, and ability is connected on the pipeline; On another straight-through port internal thread is arranged, screw thread rigid connector on another straight-through port, the upper end of connector is with meter connector; It is characterized in that: a filter screen is arranged in straight-through port, and filter screen is a cylindrical shape, is evenly distributed with aperture on the screen wall, ability filtered fluid piezodielectric; At filter screen a compression spring is arranged, there is a valve ball outer end of compression spring; Screw thread is fixed with tubular ball seat on the housing straight-through port, and ball seat has center pit and the inner that conical sealing surface is arranged; Compression spring promotes valve ball and can be sealed on the sealing surface of ball seat; A push rod is arranged in the ball seat center pit, and the inner of push rod is against on the surface of valve ball; In the vertical port outer wall of housing bottom a screw is arranged, be fixed with draining connector on the screw, and this screw is communicated with transverse holes on the ball seat; Inwardly promote push rod and can make valve ball leave the sealing surface of ball seat, play the effect of putting pressure.
After push rod is inwardly advanced, can make hydraulic seal, on push rod, be with rubber cushion, the gland screw thread is fixed on the outer end of ball seat; Push rod passes the gland center pit, is fixed with a pressure cap in the end thread of push rod.
The use of summary multi-functional pressure meter connector.Consult Fig. 1.Be connected on the pipeline and the setting pressure table.Before the dismounting tensimeter, press quick emptying pressure cap 9, tensimeter is carried out the emptying pressure release.When emptying, promote push rod 7 back valve balls 4 and leave ball seat 5; Pressure is from ball; 5 and push rod 7 between annular space discharge, discharge from draining connector 10, reach the purpose (because the annular space of ball seat and push rod has the rubber cushion sealing load to discharge from drain) of quick emptying.Getting back to the effect that reaches sealing on the ball seat 5 under the effect of compression spring 12 thrusts when unclamping behind the push rod 7 valve ball 4.Filter screen 11 is installed in meter connector, is made into that gas, the liquid of tensimeter pressure guiding pipe filter, prevent that the tensimeter tracting pressuring hole from stopping up, cause the inaccurate and tensimeter of measured value to damage.The mode of making tensimeter connection articulation change screw thread sealing in the past is a gasket seal, can regulate the tensimeter installation direction.Meter connector not only has the effect that can connect tensimeter and operation valve, but also has emptying, adjustment tensimeter direction; Filter the function that gets into tensimeter pressure guiding pipe measured medium.
The beneficial effect of the utility model: the utility model multi-functional pressure meter connector; Prove through rig-site utilization; Compare with the pressure tapping of present use, have easy to operately, simple in structure, have higher safety, reliability; In use greatly degree stopped tensimeter tracting pressuring hole phenomenon of blocking, can avoid in the process that tensimeter is installed, taking place band press operation phenomenon.
