Abstract
The utility model discloses an expansion valve of an air-conditioning device, belonging to technical field of expansion valve aiming at providing the expansion valve of the air-conditioning device using only one valve, comprising a valve body, an upper liquid flowing pipe, a lower liquid flowing pipe, a valve core, a throttling part and a pressure sensing room; wherein, the valve core is arranged inside an inner cavity of the valve body; the pressure sensing room is arranged at the left end of the valve body and is provided with an upper port and a lower port of the sensor which is isolated and sealed by a pressure sensor film from the inner cavity; the pressure sensor film is connected with the valve core using a drive rod; one end of a spring is restored to be connected with the right end face of the pressure sensor film and the other end is fixed on the valve body. The utility model has the advantages of being used in air-conditioning device, reducing weight and size and lowering production cost using only one expansion valve.
Description
Technical field:
The utility model belongs to aircondition expansion valve technical field.
Background technique:
The air conditioner that sell in market in the pipeline between condenser and vaporizer, has the refrigeration expansion valve and the solenoid valve thereof of two parallel connections and heats expansion valve and solenoid valve thereof, uses respectively when freezing and heating.Owing to use two expansion valves, whole aircondition volume increases, and weight increases, and manufacture cost increases.
Summary of the invention:
Technical problem to be solved is, but a kind of expansion valve that adopts the expansion function that a two-way flow can realize freezing, heating is provided.
It is as follows to solve the technological scheme that its technical problem adopts: the expansion valve of aircondition, comprise valve body, upper fluid-through tube, lower fluid-through tube, spool, go up throttling element, throttling element, pressure sensing chamber, pressure sensor membrane, sensor are suitable for reading down, sensor end opening, drive link and recovery spring.Upper fluid-through tube and lower fluid-through tube are arranged on the valve body, and upper fluid-through tube is connected with the fluid pipeline of condenser, and lower fluid-through tube is connected with the fluid pipeline of vaporizer.Inner chamber is arranged in the valve body, and spool is arranged in inner chamber.The last throttling element that center hole is arranged is between inner chamber and upper fluid-through tube, and its center hole is up big and down small; The following throttling element that center hole is arranged is between inner chamber and lower fluid-through tube, and its center hole is up-small and down-big.Pressure sensing chamber is positioned at the left end of valve body, and the suitable for reading and sensor end opening of sensor is arranged on it, and suitable for reading the connection with lower fluid-through tube of sensor experienced wherein pressure, and the sensor end opening is communicated with the vaporizer gas pipeline experiences wherein pressure.Pressure sensing chamber communicates with inner chamber, pressure sensor membrane is housed with inner chamber and pressure sensing chamber's separation and sealing between pressure sensing chamber and inner chamber, be connected with drive link between pressure sensor membrane and the spool, recovering spring housing is contained on the drive link, one end is connected with the pressure sensor membrane right side, and the other end is fixed on the valve body.Pressure sensor membrane can be a diaphragm, and also bellows is experienced the pressure difference between the suitable for reading and sensor end opening of sensor.
With the refrigeration is example, illustrates that its working state is as follows: during refrigeration, the high temperature high pressure liquid of being exported by condenser is flowed into by upper fluid-through tube, reaches throttling element down through last throttling element, inner chamber, flows out low-temp low-pressure liquid by lower fluid-through tube, to evaporator.At this moment, pressure sensor membrane is experienced the poor of lower fluid-through tube pressure medium and evaporator outlet pressure.If the medium degree of superheat of evaporator outlet increases, pressure increases, and then the pressure difference experienced of pressure sensor membrane reduces, and spool is moved to left, and the aperture of valve increases, thereby increases the flow of valve, and the evaporator outlet degree of superheat is reduced, and reaches new balance.
The utility model is used for aircondition, and its beneficial effect is to change existing two expansion valves into an expansion valve, but two-way flow realizes refrigeration, heats, and has cancelled solenoid valve, can reduce the weight and volume of aircondition significantly, reduces production costs.
