Abstract
The invention aims to provide a three-way throttle valve used for a heat-pump hot-water air conditioning unit, which comprises a one-way valve A, two unilateral-connecting and reverse-throttling overpressure flow dividers B and C which are in parallel connection through a three-way connection tube; and the other end of the throttle valve is provided with the connecting tubes 1, 2 and 3 of a heat exchanger of an outdoor unit, an heat exchanger of a hot water tank and an indoor heat exchanger. The throttle valve of the invention has overpressure protection function, and also leads a liquid-sate refrigerant to enter an evaporator in a foggy mode, thereby being more beneficial to improving speed and efficiency of evaporation.
Description
Technical field
The present invention relates to the heat pump hot water air conditioning The Application of Technology, particularly be applied to by five-way heat pump hot water air conditioning reversing valve as the conversion, its throttle part.
Background technology
At existing throttling arrangement, capillary, electromagnetic throttle valve, electric expansion valve, heating power expansion valve etc. do not have a kind of being suitable for by the throttle part of five-way heat pump hot water air conditioning reversing valve as the heat pump hot water air conditioning conversion at present.
Summary of the invention
The object of the present invention is to provide a kind of heat pump hot water air conditioning, its threeway throttling arrangement by five-way heat pump hot water air conditioning reversing valve control conversion, this device can also avoid high pressure too high, this device can enter into evaporimeter with vaporific form with liquid refrigerants, so more is of value to the speed and the efficient that improve evaporation.
The present invention is realized by following technical scheme: comprise a check valve A, two reverse throttlings of unidirectional conducting and superpressure flow divider B, C, tube connector 1,2,3, three-limb tube 4; Be connected in parallel by the end of three-limb tube 4 check valve A, two reverse throttlings of unidirectional conducting and superpressure flow divider B, C, its other end is respectively with tube connector 1,2,3 and is connected, tube connector 1 is and off-premises station heat exchanger tube connector, tube connector 2 is and boiler heat exchanger tube connector, and taking over 3 is tube connector with indoor heat converter.
Check valve is at valve body 10 and respectively be provided with the sealing surface of a band tapering above the movable spool 11, when conducting pressure by pipeline, movable spool 11 is promoted toward micro-force spring 12 directions, the sealing surface of two band taperings separately, refrigerant forms path by the gear-like passage of movable spool 11 again by sealing surface separately, is subjected to the pressure of pipeline and the promotion of micro-force spring 12 to make the sealing surface of two band taperings be in sealing oppositely the time.
Reverse throttling of unidirectional conducting and superpressure flow divider, valve body 20 is provided with the sealing surface of a band tapering, movable spool 21 is that gear-like is cylindrical, there is a cylindrical hole at the center, the sealing surface that two band taperings are arranged, movable spool 22 great circles are that gear-like is cylindrical, roundlet is a shower nozzle, be provided with the sealing surface of a band tapering before the shower nozzle, liquid cap 23 is that gear-like is cylindrical, the effect of spring 24 is that movable spool 21 is combined with the sealing surface of two band taperings of valve body 20, and micro-force spring 25 effects are that movable spool 22 is combined with the sealing surface of two band taperings of movable spool 21: the refrigerant body is by screen pack 26 when being in unidirectional conducting, the endoporus of movable spool 21, (will be under the effect of the refrigerant body of being with pressure by movable spool 22 micro-force spring 25 compressions, thereby the sealing surface that makes two band taperings is separately) sealing surface of two band taperings separating of movable spool 21 and movable spool 22, the gear-like passage of movable spool 22 forms passage; Spring 24 makes movable spool 21 combine with the sealing surface of two band taperings of valve body 20 when being in throttling, the refrigerant body and the micro-force spring 25 of band pressure make movable spool 22 combine with the sealing surface of two band taperings of movable spool 21, yet the refrigerant body can only spray with vaporific form by the nozzle of movable spool 22; Refrigerant body effect when being in superpressure down by movable spool 21 with spring 24 compressions, yet the sealing surface of two band taperings that the refrigerant body separates by valve body 20 and movable spool 21, the gear-like tunnel-shaped of movable spool 21 become split channel.
Beneficial effect
Beneficial effect of the present invention: 1, provide a kind of heat pump hot water air conditioning, its threeway throttling arrangement by five-way heat pump hot water air conditioning reversing valve control conversion; 2, this device can also be avoided the burden and the lossy compression method machine of high pressure too high meeting increasing the weight of compressor; 3, this device can enter into evaporimeter with vaporific form with liquid refrigerants, so more is of value to the speed and the efficient that improve evaporation.
Description of drawings
Fig. 1 is for being gear-like cylindrical cross-section figure;
Fig. 2 is the three-way throttle valve overall diagram.
Symbol in the accompanying drawing: check valve A, the reverse throttling of unidirectional conducting and superpressure flow divider B, C, tube connector 1,2,3, three-limb tube 4; Check valve valve body 10, movable spool 11, micro-force spring 12, screen pack 13; Reverse throttling of unidirectional conducting and superpressure flow divider valve body 20, movable spool 21, movable spool 22, liquid cap 23, spring 24, micro-force spring 25, screen pack 26.
The specific embodiment
Check valve A, the reverse throttling of unidirectional conducting and superpressure flow divider B, C are connected in parallel by three-limb tube 4, the other end is connected with tube connector 1,2,3 respectively, tube connector 1 is and off-premises station heat exchanger tube connector, tube connector 2 is and boiler heat exchanger tube connector that tube connector 3 is and the indoor heat converter tube connector.
This three-way throttle valve can be realized four kinds of patterns: 1, tube connector 1 is a high pressure, check valve A was a closed condition when tube connector 3 was low pressure, reverse throttling of unidirectional conducting and superpressure flow divider B are conducting state, and reverse throttling of unidirectional conducting and superpressure flow divider C are throttle; 2, tube connector 1 is a low pressure, check valve A was a closed condition when tube connector 3 was high pressure, and reverse throttling of unidirectional conducting and superpressure flow divider B are throttle, and reverse throttling of unidirectional conducting and superpressure flow divider C are conducting state; 3, tube connector 2 is a high pressure, tube connector 1 during for low pressure, and check valve A is a conducting state, and reverse throttling of unidirectional conducting and superpressure flow divider B are throttle, and reverse throttling of unidirectional conducting and superpressure flow divider C are closed condition; 4, tube connector 2 is a high pressure, tube connector 3 during for low pressure, and check valve A is a conducting state, and reverse throttling of unidirectional conducting and superpressure flow divider C are throttle, and reverse throttling of unidirectional conducting and superpressure flow divider B are closed condition.
