Abstract

The throttle device includes at least one electronic expansion valve loop, 0-10 capillary loops and 0-10 serial loop of capillary and solenoid valve, and features that all the loops are connected in parallel and the serial capillary and solenoid valve loop has solenoid valve connected to the inlet of the capillary. Using capillary as throttle element results in simple manufacture and low cost, and using solenoid valve, rather than electronic expanding valve, has low cost. By means of the regulation of different loops, the switch and the basic loop, the present invention has greatly expanded refrigerating amount regulation range, low production cost and high technological indexes.

Description

The throttling arrangement of a kind of electric expansion valve and capillary paralleling

Technical field

This patent belongs to refrigeration system throttling arrangement control method and composition, and particularly a kind of throttling arrangement that comprises electromagnetic expanding valve belongs to refrigeration and field of air conditioning.

Technical background

In traditional refrigeration system, most systems adopts capillary or heating power expansion valve to carry out throttling.And in recent years, along with industrial expansion, the price of electric expansion valve is more and more lower, within the specific limits, has been lower than the price of heating power expansion valve.And electric expansion valve has, and adjustable range is wide, load adaptability strong, the accuracy advantages of higher, but the cold of electric expansion valve is limited in scope, and big electric expansion valve price is very expensive, and the maximum cold of now domestic electric expansion valve cheaply has only about 30kw.Patent of invention 03116026.3 has proposed the throttle mechanism of heating power expansion valve and capillary paralleling according to situation at that time, lowered product cost to a certain extent, it is high and propose that this is based on the electronic Expansion Valve Control difficulty, and patent: a kind of insertion type autonomous intelligence throttling arrangement has just solved this problem.

This patent is exactly under this prerequisite, has proposed the throttling arrangement of a kind of electric expansion valve and capillary paralleling, and this throttling arrangement is keeping the simple dilatation that realizes containing the throttling arrangement cold of electric expansion valve under the situation cheaply.Can with existing refrigeration system compatibility, thereby the R﹠D cycle that has reduced product like this give full play of energy-conservation, wide accommodation, accurate advantage that electric expansion valve has.

Patent content

This patent has designed the throttling arrangement of a kind of electric expansion valve and capillary paralleling.Comprise and contain an electric expansion valve (1) loop (2), capillary (3) loop (4) (from 0-10) and capillary (3) and magnetic valve (5) series loop (6) (from 0-10) at least, it is characterized in that: be relation in parallel between each loop, capillary and magnetic valve series loop are to connect magnetic valve (3) in capillary (2) porch.Capillary is as a kind of restricting element commonly used, and manufacturing is simple, cost is cheap, and magnetic valve is also more than the electric expansion valve low price.Regulating (electric expansion valve loop), switch (magnetic valve) and fundamental circuit and can widen throttling arrangement refrigerating capacity adjustable range greatly by different circuit.

Specific embodiment

The throttling arrangement of a kind of electric expansion valve and capillary paralleling, form by three loops, one of them electric expansion valve loop, the refrigerating capacity of corresponding throttling is 30kw, a capillary loop, and the refrigerating capacity of corresponding throttling is 30kw, one capillary and magnetic valve series loop, the refrigerating capacity of corresponding throttling is 30kw, and the refrigerating capacity adjustable range of this like this throttling arrangement just can be 90kw, and can regulate by continuous stepless.

Claims

1. the throttling arrangement of electric expansion valve and capillary paralleling, comprise and contain an electric expansion valve (1) loop (2), capillary (3) loop (4) (from 0-10) and capillary (3) and magnetic valve (5) series loop (6) (from 0-10) at least, it is characterized in that: be relation in parallel between each loop, capillary and magnetic valve series loop are to connect magnetic valve (5) in capillary (3) porch.

2. capillary can be similarly to carry out other restricting elements replacements of throttling merely with geometry.
