Technical Field

[0001] The invention relates to a hand-operated and electric-integrated temperature regulating valve, which is applied to the field of fluid circuits of temperature control systems of manned spacecraft. Background Art

[0002] The temperature control fluid circuit system of manned spacecraft is an important subsystem of the spacecraft, responsible for the environmental control of astronauts and equipment. The temperature control valve is a key unit in the entire fluid circuit. The required temperature control valve needs to have a long life and reliability, and its performance is directly related to the stable operation of the temperature control system.

[0003] At present, the existing electric control valves use adjustment parts in the form of sleeves or single seats, which cannot realize the manual operation kinetic energy in emergency conditions when on orbit, and the product has low reliability on orbit; at the same time, the manual and automatic valves are heavy and large in size, and the flow resistance is large when connected in series to the system, and the adjustment accuracy is low. In order to solve the problems of low life and reliability of the temperature control valve of manned spacecraft and improve the automatic control accuracy of the fluid circuit system, it is necessary to develop a manual and electric integrated driven temperature control valve with high reliability, small weight, volume and low flow resistance. Summary of the invention

[0004] The technical problem solved by the present invention is to overcome the deficiencies of the prior art and provide a temperature regulating valve integrated with a hand and a light to solve the temperature regulation problem of manned spacecraft.

[0005] The technical solution of the present invention is: a flashlight integrated temperature regulating valve, comprising: a drive feedback monitoring component, a valve body, a flashlight split drive component, an adjustment mechanism component, a valve cover, a sealing cover, a cover plate component and an electrical connector;

[0006] The drive feedback monitoring assembly is installed in the mounting hole of the valve body through a flange. One end of the hand-held separation drive assembly is installed on the output shaft of the drive feedback monitoring assembly, and the other end passes through the inner hole of the valve body to be connected to the adjustment mechanism assembly. A second sealing ring is arranged on the valve body to ensure the sealing of the rotation process of the hand-held separation drive assembly. The valve cover and the valve body are connected by flange screws, and a first sealing ring is arranged at the connection between the two to form a sealed liquid cavity, and the adjustment mechanism assembly is wrapped in the sealed cavity. The sealing cover is fixed to the valve body through a flange to limit the axial and circumferential freedom of the drive feedback monitoring assembly. At the same time, a sealing ring is arranged to achieve sealing between the sealing cover and the valve body. ; The cover plate assembly is installed on the valve body and is sealed with a sealing gasket to form a sealed cavity, providing a working environment for the drive feedback monitoring assembly and the flashlight split drive assembly; electrical connectors are installed on the sealing cover and the valve body for power supply control and position monitoring of the drive feedback monitoring assembly; the flashlight integrated temperature control valve is connected to the external system fluid circuit through the pipeline of the valve cover, and is connected to the host computer control system through the electrical connector; when the system needs to adjust the temperature, a control signal is sent to the drive feedback monitoring assembly to make it rotate, and drive the adjustment mechanism assembly to rotate, and cooperate with the valve cover to adjust the main and bypass flow, thereby achieving system temperature regulation.

[0007] The drive feedback monitoring component includes: a stepper motor component, a reduction component, a potentiometer component, a flaring pin, a first mounting screw and a second mounting screw; the stepper motor component housing is positioned with the mounting flange at one end of the reduction component housing through the motor mounting flange and is fixed by the first mounting screw; the flange at the other end of the reduction component housing is positioned and connected with the mounting flange of the potentiometer component by the second mounting screw; a square boss is provided at the output shaft end of the rotating part of the reduction component for transmitting torque, and at the same time, the output shaft of the reduction component is connected with the rotating shaft of the potentiometer component by the flaring pin to realize axial positioning and torque transmission; the entire drive feedback monitoring component is axially and radially positioned and fixed by the flange of the reduction component and the valve body.

[0008] The stepper motor assembly adopts two-phase, four-phase or other forms of mechanisms according to working requirements; the reduction assembly adopts a gear reduction mechanism or a harmonic reduction mechanism according to working requirements, or adopts a combination of a gear reduction mechanism and a harmonic reduction mechanism to adjust the reduction ratio.

[0009] The flashlight split drive assembly is used for switching the electric automatic control and manual control functions of the temperature control valve, and includes a valve stem, a fixed wrench and a movable wrench; wherein a pin hole and a positioning boss for connecting the adjustment mechanism assembly are arranged at one end of the valve stem, and a square boss is arranged at the other end of the valve stem, and is inserted into the connecting square hole on the fixed wrench to realize axial positioning and circumferential limiting of the two parts and perform torque transmission. At the same time, a rectangular boss is arranged on the fixed wrench for connecting with the movable wrench; an open groove and a rectangular groove for transmitting torque are arranged on the movable wrench; when the movable wrench is inserted into the feedback monitoring assembly and the fixed wrench from the side, the open groove cooperates with the square boss at the output shaft end of the reduction assembly, and the rectangular groove cooperates with the rectangular boss of the fixed wrench. After installation, the feedback monitoring assembly and the flashlight split drive assembly are connected as one for torque transmission. After the valve stem passes through the valve body, the dynamic seal is ensured by a second sealing ring.

[0010] When electric drive is used to control the system temperature, keep the adjustable wrench inserted into the fixed wrench, and the feedback monitoring component is connected to the valve stem. When the feedback monitoring component receives the signal from the host computer, the valve stem is driven to drive the adjustment mechanism component to adjust the main bypass flow of the system. At the same time, the position of the valve stem is fed back through the potentiometer component, and then the actual opening of the temperature control valve is obtained through decoding by the host computer; when the electric drive fails or manual drive is required to control the system temperature, the adjustable wrench is taken out, and the feedback monitoring component is separated from the flashlight split drive component. At this time, the fixed wrench is pulled to drive the valve stem to drive the adjustment mechanism component to adjust the main bypass flow of the system to achieve manual drive control. After the test is completed, the adjustable wrench is inserted to switch to electric drive mode.

[0011] The regulating mechanism assembly is a compact flat disc structure, consisting of a spring seat, a spring, and a sliding disc; the spring seat is a stepped shaft with a center hole, installed on the valve stem positioning boss, and is used for positioning and installing the spring end; the other end of the spring is installed on the sliding disc; a medium inlet flow channel, a medium main outlet flow channel, and a medium bypass outlet flow channel are arranged on the sliding disc, wherein the medium main outlet flow channel and the medium bypass outlet flow channel are structured as triangular windows, extending along the rotation direction of the shaft, and are used to adjust the flow area of ​​the valve and thus adjust the system flow, the main channel and the bypass channel have the same structure, and extend in opposite directions; after the spring is installed, the sliding disc is pressed against the valve cover, and the spring provides sealing force at the same time, so as to realize the internal sealing of the temperature regulating valve.

[0012] The valve cover and the valve body are positioned at the flange and connected and fixed by fasteners; the valve cover and the valve body are sealed by a first sealing ring; the valve body and the valve stem are sealed by a second sealing ring, and a sealed liquid cavity is formed after the valve cover is installed; the valve cover is composed of an inlet flow channel, a main flow channel, a bypass flow channel and a valve seat, wherein the medium enters the valve cover from the inlet flow channel, flows through the inlet channel of the valve seat into the sealed liquid cavity, passes through the regulating mechanism assembly, and then flows out to the main flow channel and the bypass flow channel through the main channel and the bypass channel of the valve seat respectively.

[0013] The structure and material of the valve cover are processed in one piece or in two pieces according to actual working conditions; when the required service life is relatively short, the valve cover is processed in one piece using aluminum alloy, and a flat boss is opened on the valve seat, and the flat boss is anodized to increase the surface hardness; when the required service life is relatively long, the valve seat is processed in two pieces, and a material with a small friction coefficient is selected, including metal, non-metal or combined composite materials; after the two-piece processing, a third sealing ring is used to ensure the external seal, and a sealing gasket is used to isolate the main and bypass flow channels to ensure the internal seal.

[0014] The sliding plate is pressed against the flat boss by a spring to provide an initial sealing force. When the valve stem is driven electrically or manually, the valve stem drives the sliding plate to reciprocate within a preset range. At this time, the main medium outlet flow channel of the sliding plate cooperates with the main channel of the valve cover, and the medium bypass outlet flow channel of the sliding plate cooperates with the bypass channel of the valve cover to form different throttling areas at different angles, thereby realizing system flow distribution adjustment and further adjusting the system temperature.

[0015] When the equipment is connected to the system and works, the medium flows in from the valve cover inlet, passes through the internal flow channel of the valve cover, flows into the sealed liquid cavity, flows through the sliding disc special-shaped window and the main and bypass outlet flow channels of the valve seat, and then flows out through the valve cover outlet; if the temperature in the system needs to be reduced, the flow of the main path is increased, the valve stem is driven to drive the sliding disc to rotate, the main path opening is adjusted to increase, the throttling area is increased, and the flow rate is increased; if the temperature in the system needs to be increased, the flow of the main path is reduced, the valve stem is driven to drive the sliding disc to rotate, the main path opening is adjusted to decrease, the throttling area is reduced, and the flow rate is reduced;

[0016] When electric control is adopted, the upper computer sends a pulse signal to the drive feedback monitoring component to drive the valve stem to feedback the opening value of the temperature control valve. PID control technology is used according to the system temperature and the opening feedback of the temperature control valve to realize automatic control of the system temperature. When manual control is adopted, the cover assembly is opened, the adjustable wrench is taken out, and the drive feedback monitoring component is separated from the valve stem. At this time, a fixed wrench is used to drive the valve stem to adjust the valve opening to realize manual control of the system temperature. When the electric drive needs to be enabled again, the adjustable wrench is inserted into the original position to connect the drive feedback monitoring component to the valve stem and enter the electric control mode.

[0017] The advantages of the present invention compared with the prior art are:

[0018] (1) The existing commonly used temperature control valves have low life reliability. The hand-operated integrated temperature control valve designed in the present invention has a manual backup function, which can realize rapid switching between electric and manual drive without affecting each other and has high reliability.

[0031] Furthermore, when the temperature of the system is controlled automatically by electric means, the movable wrench 33 is kept inserted into the fixed wrench 32, and the feedback monitoring component 1 is connected to the valve stem 31 as a whole. When the feedback monitoring component 1 receives a signal from the host computer, the valve stem is driven to drive the regulating mechanism component 4 to adjust the main bypass flow of the system. At the same time, the position of the valve stem 31 is fed back through the potentiometer component 13, and then the actual opening of the temperature control valve is obtained through decoding by the host computer; when the electric function fails or manual drive is required, the movable wrench 33 is taken out, and the feedback monitoring component 1 is separated from the flashlight split drive component 3.
