Abstract

The utility model is an auto trailing pressure regulator which is communicated with a pressure vessel through a piston. The piston is connected with a tray, proper poise groups are arranged on the tray or/and a proper controllable power; the power is trailed on the tray or poises through a cable; the other end of the cable is connected with the reel of a windlass. The device can reasonably select the diameter of the piston or proper poise group, or the trailed controllable power; namely the utility model is trailed on the tray or the poises through a cable and then is connected with the reel of the windlass; the pressure of the pressure vessel can be adjusted through the on-off of the motor. A stepper motor is preferably selected, and then a proper motor torque, a proper worm gear transmission ratio, and the reel diameter are selected to realize auto pressure regulating. The device serves for deep-sea simulating test field, and can be applied to other high-pressure controlling field, such as war industry, space field, valve and pipe pressure testing field.

Description

Automatically draw regulator

(1) technical field

The utility model relates to the improvement of the pressure test container pressure regulation technology of deep-sea simulation test, specifically is a kind of automatic traction regulator, 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.

(3) technology contents

The purpose of this utility model provides a kind of automatic traction regulator, and this device is that airtight high pressure vessel is carried out pressure control, because controlled object pressure is very high, and controlled pressure significantly changes more easily.This device can be realized the automatic adjusting of the pressure of pressure vessel, reaches automatic supercharging, the automatically purpose of step-down, and the gradient that increases, reduce pressure is stablized and can set arbitrarily, has overcome the defective of conventional hydraulic valve.This device can also overcome the possibility of the pressure moment forfeiture that exists in laboratory simulation test, avoid possible device damage.This Design of device is especially 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 traction regulator, and it is connected in pressure vessel by piston.Described piston is connected with pallet, and being placed with suitable weight group and/or traction on this pallet successively has suitable controlled power, and on pallet or counterweight, the other end of this rope is connected on the spool of windlass this power by cable traction.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.Described controlled power, it is gear train and windlass that controllable motor drives, controllable motor or be stepper motor wherein, or be stepless speed-change motor.Described controllable motor, its moment of torsion is at 0--50NM.Described gear train, its ratio of gear are 1: 5--1: 100.Described gear train, itself or be worm couple, or be gear pair.The spool of described windlass, its diameter is at 5--20mm.

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 automatic pressure regulating device.Described piston is connected with pallet, selects successively on this pallet to be placed with suitable weight group.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 controlled power of suitable traction according to the scope of goal pressure, on pallet or counterweight, the other end of this rope is connected on the spool of windlass this power by cable traction.This device drives worm couple by the rotation of motor, drives spool, produces the pulling force to rope, and rope can directly be connected with pallet, the pressure that comes counterpoise to produce; By the start-stop of automatic control motor, the positive and negative pressure size of regulating container that transfers.The preferred stepper motor of motor, the diameter of matching suitable Motor torque and worm gear transmission ratio and spool again reaches the purpose of automatic Regulation.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.
