Abstract
An auto pressure regulator device is communicated with a pressure container by a piston. The piston is connected with a pallet which is provided with a weight group and/or a box group in sequence. The pressure regulator device controls and regulates the container pressure by selecting rational piston diameter or placing proper weight group, and/or changing liquid quantity in the box group by pump or manpower, namely by pumping or drawing liquid to increase or reduce weight of the box group. In this way, the pressure regulator device realizes pressure regulation and automatically increases or decreases pressure, while increasing and decreasing gradients can be preset, thereby overcoming shortcomings of traditional hydraulic valve and eliminating pressure change caused by temperature change. The device is designed for applications on occasions of deep marine simulation experiment as well as other occasions relating to high pressure regulation such as the military industry, the aerospace industry, the valve component pressure commissioning, etc.
Description
(1) technical field
The utility model relates to the improvement of the pressure test container pressure automatic adjustment technology of deep-sea simulation test, specifically is a kind of automatic pressure regulating device, and it belongs to modelling technique field, deep-sea.
(2) background technology
In the simulation test of deep-sea, generally about 1-60Mpa, pressure is higher for working pressure, and generally about 2, temperature is lower for temperature, need accurately control temperature and pressure at the laboratory simulation deep-marine-environment.The range of adjustment that generally requires controlled pressure is at 1-60MPa, and temperature regulating range is at-5--40, and the control accuracy of pressure is less than 0.5%.Pressure control generally is to use the pressure-regulating valve door at industrial circle, controls by the aperture size of by-pass valve control.But for the deep-sea simulation test, because the principle of work of valve, adjusting to pressure has the factors of instability, thereby the aperture of by-pass valve control, do not reach purpose accurate, that stablize controlled pressure, can not realize pressurizeing uniformly and stably and decompression process, can not the real simulated deep-sea process of test, even might damage laboratory sample and instrument component.And be operated in the above pressure regulating valve of 40MPa pressure and almost do not have, therefore this method of coming controlled pressure with pressure regulating valve just becomes not too accurately or needs the pressure regulating valve of special machining high-precision for the deep-sea simulation test.Certainly will cause deep-sea simulation test cost very expensive like this, and precision also not necessarily can reach the desired control precision.Cause often having in laboratory simulation test the situation of pressure moment forfeiture, just there is the possibility of damage equipment in this.And, traditional compress control method, container medium variation of temperature also can cause the variation of pressure in the test chamber, and this has just caused the instability of pressure, even produces dangerous.
(3) technology contents
The purpose of this utility model is to overcome the defective that above-mentioned conventional hydraulic valve comes controlled pressure, and a kind of automatic pressure regulating device is provided.This device is that airtight high pressure vessel is carried out automatic pressure control, because controlled object pressure is very high, and controlled pressure significantly changes more easily.This device will be realized the automatic adjusting of the pressure of pressure vessel, reaches the purpose of supercharging, step-down, and the gradient that increases, reduces pressure is stable and can ownly set arbitrarily, has overcome the defective of conventional hydraulic valve.This device also will overcome the possibility of the pressure moment forfeiture that exists in laboratory simulation test, avoid possible device damage.This device also will stably make pressure remain on the position of setting, and can thoroughly eliminate the pressure variation that produces owing to temperature variation.This Design of device is most important to the environment of building the test of simulation deep-sea.
Task of the present utility model is finished by following technical scheme, has developed a kind of automatic pressure regulating device, and it comprises: pressure vessel, piston.This pressure vessel is connected in piston by pipeline, the other end of this piston is connected with the bottom of pallet again, the casing group that the top choosing successively of this pallet is placed with suitable weight group and/or suitable volume is equipped with liquid in all casings of this casing group, and all casing groups are connected with pump and/or pipeline indirectly.
Described weight group, the weight range of its choose reasonable is at 0-150Kg, and the substance of every piece of counterweight is at 1--5Kg.The casing group of described suitable volume, its total amount of liquid that holds is at 0--200L.
Advantage of the present utility model is: because this device is to connect in pressure vessel by piston.According to the goal pressure scope of pressure vessel, can reasonably select the diameter of piston.The pressure control of pressure vessel is mainly finished by this regulator.Described automatic pressure regulating device, it comprises: pressure vessel, piston.This pressure vessel is connected in piston by pipeline, the other end of this piston is connected with the bottom of pallet again, the casing group that the top choosing successively of this pallet is placed with suitable weight group and/or suitable volume is equipped with liquid in all casings of this casing group, and all casings are connected with pump and/or pipeline indirectly.Therefore, can reasonably select the size of counterweight and the pressure that container was controlled and regulated to number according to the scope of goal pressure; Can also reasonably select the casing group of suitable volume according to the scope of goal pressure, change amount of liquid in this casing that communicates by pump by the liquid that is equipped with in all this casings.Promptly bear a heavy burden and regulate the pressure of container by increase and decrease, just the mode by injection and extraction liquid realizes the increase and decrease heavy burden, the injection of this liquid and extract out and can realize by the pump of automatic control also can be manually threaded a pipe indirectly by all casings and is injected and extracts liquid and realize increasing and decreasing the casing heavy burden.This regulator is realized the adjusting of pressure by the mode of injection and extraction liquid, reach the purpose of automatic supercharging, decompression, and the gradient that increases, reduces pressure can set, and overcome the defective of conventional hydraulic valve, and can eliminate because the pressure that temperature variation causes changes.This device is to serve for the place that relates to the deep-sea simulation test, also can be applicable to the place that other relate to high-pressure control, for example: services such as military project, space flight, the pressure testing of valve pipe fitting.
