Description
Technical field
The utility model relates to the normal-open electromagnetic valve of throttling under a kind of closed condition and low noise.
Background technique
Normal-open electromagnetic valve is mainly used in dehumidifying and does not lower the temperature in the high-grade air-conditioning, is used for connecting two indoor evaporator.Existing a kind of solenoid valve needs to use with capillary paralleling in air-conditioning, and under solenoid valve energising closed condition, refrigerant plays throttling action by capillary tube, uses this solenoid valve in air-conditioning, and solder joint is many, manufacture cost is high.The spy opens 2003-156269 and discloses a kind of solenoid valve, it comprises coil and connected valve body, described valve body comprises valve seat, place sleeve pipe and sealing head on the valve seat, have radial direction through hole and axial bore on the sealing head, two holes communicate and form the throttling path under the valve closed conditions, for reaching low noise, in the throttling path, be equipped with two bubble sectionalization devices outward, this bubble sectionalization device is a foaming metal, porous matter plastics, the reticulated work that metal wire knitted becomes or be installed with the sheet metal in several holes, structure is complicated, and bubble sectionalization Unit Installation inconvenience and fabricating cost are higher.
The model utility content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of simple in structure, easy for installation, the throttling that fabricating cost is low and the normally open solenoid valve of low noise are provided.
For this reason, the technical solution adopted in the utility model is as follows: throttling, the low noise normally open solenoid valve, comprise coil and connected valve body, described valve body comprises valve seat, place sleeve pipe and sealing head on the valve seat, have radial direction through hole and axial bore on the sealing head, two holes communicate and are communicated with the cavity that is positioned at sealing head, under the valve closed condition, form throttling passage, cavity is built-in with throttling arrangement and silencer, it is characterized in that opening in the described throttling arrangement axial hole, axial hole communicates with axial bore, and silencer is a many gaps body that is formed by the wire coiling.Axial hole in the throttling arrangement in the utility model plays throttling, stablizes and close the effect of valve flow, has further improved restriction effect (throttling passage also has been a restriction effect); Silencer is shaped by one whole wire coiling, and its shape can be cylindrical or spherical, can effectively suppress the generation of noise when many gaps of refrigerant by silencer.Throttling, the silencer that the utility model adopts is simple in structure, easy for installation and fabricating cost is low; Throttling, flat better effects if.
Described throttling, low noise normally open solenoid valve, there is a porous gasket silencer below, and this porous gasket and sealing head are affixed, play the effect of fixed restriction device, silencer, also have the mobile function of noise that reduces refrigerant.
Described throttling, low noise normally open solenoid valve, the mounting point of throttling arrangement and silencer can be changed, and selects according to actual needs.
Described throttling, low noise normally open solenoid valve, throttling arrangement and silencer are positioned on the interior step of cavity, are in steady state when both are worked.
Described throttling, low noise normally open solenoid valve have an expansion chamber that places throttling arrangement top in the cavity, further reduce noise.
The beneficial effects of the utility model are: simple in structure, easy for installation, fabricating cost is low; Throttling, flat better effects if.
Below in conjunction with drawings and Examples the utility model is further described.
