The chamber is arranged in the base. The throttling chamber is provided with a throttle table on the base. The fluid flows through the gap between the lower film and the throttle port to generate a liquid resistance, and the lower side of the oil supply passes through the throttle plate and the lower film. The gap and the throttling 'Qing oil supply and flow to the working conditions; the upper side of the oil is used to pre-press _, so that τ__ in the initial state of the work side force of the initial gap of 201216027 is the default value, and meet the static Operating conditions of the pressure element. The external oil supply enters the upper and lower sides of the lower film of the restrictor through the inlet passage, and the pre-pressure side oil passage is pre-pressed by the vertical connecting hole to the pre-pressing chamber, wherein the throttle screw-end system is fixed. External thread, another end made of a spiral-shaped capillary 'oil supply through the capillary into the side of the _, the use of the gap of the capillary tube to create throttling resistance, the outer end of the orifice has internal thread, throttling • threaded installation In the orifice, the outlet pressure of the capillary is determined by the effective working length of the capillary spiral. 'The longer the micro-path of the capillary of the oil pavement, the larger the liquid resistance is, the smaller the pre-pressure is.' In the initial state of the maintenance, the pressure on both sides of the membrane is adjusted to be in equilibrium. The film has an initial pre-set deformation amount. When the working side force of the working side of the film is changed (4), the lower side of the lower part of the film is subjected to further deformation; when the working pressure is increased, the lower film is deformed upwards, so that the work is tilted. The opening on the side of the force • is increased. Conversely, when the working pressure is lowered, the lower film is deformed downward to reduce the opening on the working pressure side, so that the pressure and the flow rate are adjusted. An upper film is disposed between the top cover and the ring body, and the upper film and the lower film are disposed to be deformed by the size of the chamber, and the pressure of the lower film pre-compression chamber is applied to the capillary outlet. And the pressure between the upper film and the top cover [County (four) Wei hole, so that the upper film occurs 201216027 only seven times the value is difficult to maintain at atmospheric pressure, if the film is not set, the working pressure increases, causing the lower film to deform upward, squeeze The fluid vapor/package in the pressure chamber causes the pre-pressure chamber pressure to rise in a step-by-step manner, and the surface force of the original adjustment oil is not throttled after the gap between the film side throttle and the lower film fa1. It flows through the outlet hole and the connecting pipe to the working oil chamber. If the throttle installation sensor is used to monitor the internal temperature and pressure of the throttle • _ can study its working characteristics 'as the design parameter calibration; the ring system has (4) the upper hemp 'base made of radial towel to listen to and under The side hole and the upper measuring hole are radially connected to the chamber from the surface of the ring body, and the + hemp is connected from the radial direction of the wire to the space of the lower film and the throttle table, and the lower weave is radially connected to the outlet hole from the bottom wire surface; The outer end of the hole is made into a threaded seat for mounting the sensor probe. It is used to install the pressure gauge and the thermometer connector. The upper measurement system is used to monitor the pressure and temperature of the pre-pressure chamber. N, and the throttle chamber is monitored during the middle view. The pressure and temperature 'under the hole is used to monitor the throttle outlet pressure and temperature. [Embodiment] The working pressure and the flow rate are automatically adjusted when the external pressurized fluid passes through the throttle device due to the flow resistance of the fluid viscous resistance. The present invention is a film throttling that can adjust the pressure of the preloading side of the film by capillary throttling. Referring to the second figure, it is said that 201216027 realizes the implementation of its working principle. The film restrictor changes the gap between the top surface of the column of the shutoff table 153 and the lower film 14〇 to change the flow resistance, since the upper and lower _m, (10) are made of an elastic material, which has the ability to be deformed by pressure, when the oil chamber When the pressure rises, the lower film 140 will increase the gap due to the deformation of the pressure, thereby reducing the flow resistance. Conversely, when the working pressure is lowered, the deformation of the lower film 14() is also relatively reduced, so that the gap is reduced. The flow resistance is increased, and the deformation amount of the upper and lower thin ridges 120 and 14 〇 depends on the material and thickness of the film 120 and 140. The present invention is used to change the film damper under the deformation of the film damper. The film 1 uses the capillary of the printing screw 160 to adjust the pre-pressure on the upper side of the lower film, and the pressure on both sides is deformed by the net pressure on both sides, and the pre-pressure is adjusted to change the working performance caused by the deformation of the film. No longer • Limited by the effects of external pressure supply. The present invention is a "capillary-adjusted double-membrane type static pressure restrictor", as illustrated in the second figure, comprising a top cover 110, an upper film 120, a ring body 130, a throttle screw 160, a lower film 140, a base 150, The bolt 170, wherein the top cover 11 〇, the ring body 130 and the base 150 are locked and combined by a plurality of bolts 170. The external oil supply enters the upper and lower sides of the lower film 140 of the throttle device through the inlet hole 152, and the oil enters the two sides of the lower film 14〇, and the lower side of the throttle chamber 132 is provided with the 201216027 in the base 150, and the throttle chamber 132 is provided with a throttle table 153 on the base, and a liquid resistance is generated between the gripper body flowing through the gap between the lower film H0 and the throttle table, and the lower side oil supply passes through the gap between the throttle table 153 and the lower film 14 Throttle, adjust the pressure and flow of oil supply to working conditions. The pre-pressing side oil passage is pre-pressed to the lower film 140 via the vertical communication hole 151 to the pre-compression chamber 131. The throttle _ 16 〇 is a spiral capillary restrictor, and the gap between the Li Xiao Xiao capillary channels generates throttling resistance and throttling. The outer end of the hole 134 is internally threaded, the throttle thread is mounted on the annular body orifice 134, and the other end of the capillary is provided with an external thread, and the throttle hole 134 is locked with a lock; the capillary outlet pressure is capillary JL is used as the length ant. The longer the working distance through the capillary, the larger the liquid resistance is, the smaller the pre-pressure is. The upper and lower 臈12〇 and the lower film 14〇 are elastic. When the working pressure increases, the net pressure changes. Film • MG will be deformed in a step-by-step manner, with the effect of tightness and flow; when the working pressure is higher, the pressure difference between the lower film 140 increases, and the deformation of the lower film 14 increases, then the lower film M0 and the section The gap opening between the flow tables (5) is larger; on the contrary, when the working pressure is lowered, the lower film 14〇 is further deformed downward, and the smaller the working pressure, the gap between the lower film 14〇 and the throttle table 153. The smaller the opening, the working side oil After throttling the gap between the lower film 1 and Magic 14〇 expansion stage, through the outlet orifice 154 to flow to the working oil chamber. 201216027 The pre-pressure chamber 134 is between the upper film 120 and the lower film 140. The pressure of the pre-compression chamber 134 causes the upper film 12〇 to be deformed according to the magnitude of the pre-compression, and the upper film 120 and the top cover 11〇 are disposed. There are a constant pressure chamber 2〇〇 and a vent hole m, and the constant pressure chamber 200 maintains atmospheric pressure due to the vent hole ill. The implementation of the throttle ampere sensor to monitor the internal temperature and pressure of the throttle is shown in Figure 3.
