Description
Technical field
The utility model belongs to refrigeration technology field, is specifically related to a kind of check valve apparatus with throttling function.
Background technique
In the prior art, the main capillary tube that adopts comes throttling on the delivery line of refrigeration system, and refrigeration agent relies on flow resistance to produce pressure along its length during by capillary tube to fall cooling evaporation at last.Because at present capillary tube directly is serially connected on the pipeline, can't take off, so under some need not the situation of throttling, blocked flow of fluid.At present the way that solves is one-way valve in parallel on capillary tube, guarantee the smooth circulation of liquid by the allotment of one-way valve, but shortcoming is to make the refrigeration system pipeline structure complicated also to have increased cost.
Summary of the invention
The utility model purpose is: a kind of check valve apparatus with throttling function is provided, and this device rolls into one one-way valve and function capillaceous, helps to improve the refrigeration system efficiency, and can simplify the refrigeration system pipeline structure greatly, reduces cost.
The technical solution of the utility model is: a kind of check valve apparatus with throttling function comprises the valve body and the spool of one-way valve it is characterized in that described spool upper edge valve body is axially arranged with the capillary throttle orifice.
Further, valve body described in the utility model is made up of valve pipe and stuffing box gland, and described stuffing box gland is fixed on valve pipe front end, has valve pocket in the valve pipe, described valve pocket two ends respectively with valve pipe and stuffing box gland in the water conservancy diversion hole link that is provided with; Spool be located in the valve pocket and can be in valve pocket along the axial activity of valve pipe; Described center spool is provided with the capillary throttle orifice relative with the water conservancy diversion duct on the stuffing box gland; And the spool periphery is provided with some guide ribs that distribute vertically, forms guiding gutter between adjacent two guide ribs and is communicated with valve pocket.
Further, the end that spool described in the utility model points to stuffing box gland is designed to conical head, and described capillary throttle orifice is positioned at the center of conical head, then is provided with the conical surface with described conical head coupling on the described stuffing box gland.
Further, the shaft axis in the water conservancy diversion duct in the throttle orifice of capillary described in the utility model and the stuffing box gland overlaps.Preferably, the shaft axis in the water conservancy diversion duct in the water conservancy diversion duct in the pipe of valve described in the utility model and the stuffing box gland overlaps, and promptly the pipe of valve described in the utility model, the interior water conservancy diversion duct of stuffing box gland can overlap with capillary throttle orifice three's shaft axis.
Further, one end of stuffing box gland described in the utility model inserts valve pipe internal fixation.
Further, to be equal angles on the spool periphery spaced apart for guide rib described in the utility model.
The diameter of the throttle orifice of capillary described in the utility model is a techniques well known, and less than the diameter in the water conservancy diversion duct on valve pipe or the stuffing box gland.
Working principle of the present utility model is as follows: when specifically using, valve body of the present utility model is serially connected on the refrigeration system delivery line, refrigeration agent flows into valve pocket from the water conservancy diversion duct on the valve pipe, promoting spool is against on the stuffing box gland, stop up the path between spool and the stuffing box gland, make refrigeration agent in the capillary throttle orifice, to flow out, finish throttling.And oppositely the time, refrigeration agent flows into from the water conservancy diversion duct on the stuffing box gland, it is movable in valve pocket to promote spool, make refrigeration agent can flow in the valve pocket between spool and the stuffing box gland, and because the existence of guiding gutter on the spool is no longer flowed out refrigeration agent from the capillary throttle orifice, but pass through valve pocket through guiding gutter smoothly, flow out the valve pipe at last, finish reverse conducting.
The utility model has the advantages that:
1. this check valve apparatus with throttling function that provides of the utility model rolls into one one-way valve and function capillaceous, makes traditional one-way valve possess throttling function, helps to improve the refrigeration system efficiency; And the utility model is mounted on the refrigeration system delivery line can simplify the refrigeration system pipeline structure greatly, reduces cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a section of structure of the present utility model;
Fig. 2 is the utility model stereochemical structure exploded view.
Wherein: A, valve body; 1, valve pipe; 2, stuffing box gland; 3, spool; 3a, guide rib; A, guiding gutter; 4, valve pocket; 5, water conservancy diversion duct; 6, capillary throttle orifice.
Embodiment
Embodiment: in conjunction with Fig. 1, shown in Figure 2, this check valve apparatus that present embodiment provides with throttling function, it is made up of valve A and spool 3, and valve A is made up of valve pipe 1 and stuffing box gland 2.Described stuffing box gland 2 one ends insert valve pipe 1 front end and fix, and have valve pocket 4 in the valve pipe 1, and described valve pocket 4 two ends are communicated with the water conservancy diversion duct 5 that is provided with in valve pipe 1 and the stuffing box gland 2 respectively; Spool 3 be located in the valve pocket 4 and can be in valve pocket 4 along the axial activity of valve pipe 1.3 centers of spool described in the present embodiment are provided with the capillary throttle orifice 6 relative with the water conservancy diversion duct 5 on the stuffing box gland 2; And spool 3 peripheries are provided with three guide rib 3a that distribute vertically, form guiding gutter a between adjacent two guide rib 3a and are communicated with valve pocket 4.Above-mentioned three guide rib 3a are equal angles on spool 3 circumference spaced apart.The end that described spool 3 points to stuffing box gland 2 is a conical head, and described capillary throttle orifice 6 is positioned at the center of conical head, then is provided with the conical surface with described conical head coupling on the described stuffing box gland 2.The shaft axis of water conservancy diversion duct 5 threes in water conservancy diversion duct 5 in the throttle orifice 6 of capillary described in the present embodiment and the stuffing box gland 2 and the valve pipe 1 overlaps.
The working principle of present embodiment is as follows: when specifically using, present embodiment is serially connected on the air-conditioning near on the conveying pipe of refrigerant road of evaporator end, refrigeration agent flows into valve pocket 4 from the water conservancy diversion duct 5 on the valve pipe 1, promoting spool 3 is against on the stuffing box gland 2, stop up the path between spool 3 and the stuffing box gland 2, make refrigeration agent in capillary throttle orifice 6, to flow out, finish throttling.And oppositely the time, refrigeration agent flows into from the water conservancy diversion duct 5 on the stuffing box gland 2, it is movable in valve pocket 4 to promote spool 3, make refrigeration agent can flow in the valve pocket 4 between spool 3 and the stuffing box gland 2, and because the existence of guiding gutter a on the spool 3 is no longer flowed out refrigeration agent from capillary throttle orifice 6, but pass through valve pocket 4 through guiding gutter a smoothly, flow out valve pipe 1 at last, finish reverse conducting.
