Abstract
The utility model relates to a feeding valve, which is used for a jet flow material mixing system and is capable of eliminating reflux, wherein a feeding pipe (4) is connected with a material discharge pipe (5) by a valve body (1); the feeding pipe (4) is communicated with the material discharge pipe (5) by a hole passage; the feeding pipe (4) and the material discharge pipe (5) are mutually communicated with a diversion hole passage (1-1) of the valve body (1); a sealing ball (2) is arranged between the outside of the other end of the diversion hole passage (1-1) and a screw bolt (3) which is provided with an overflow hole passage (3-1). Under the action of negative pressure which is generated by the jet flow, the sealing ball (2) clogs a right end port of the diversion hole passage (1-1); the material is sucked out from the feeding pipe (4), enters a jet flow passage through the valve body (1) and the material discharge pipe (5) and is mixed with the jet flow. During the period, if a jet flow body outlet pipeline is clogged, the jet flow body changes the direction and enters the material discharge pipe (5) to form the reflux. At the moment, the negative pressure disappears instantly so that the sealing ball (2) is loosened automatically; the reflux is discharged by the diversion hole passage (1-1), the overflow hole passage (3-1) and an overflow hole passage (1-2). The utility model is applied for water jet flow cutting systems.
Description
Affiliated technical field
The utility model relates to a kind of inlet valve that is used for the jet mixing system, and the negative pressure of especially utilizing jet to produce realizes the feed open and close and gets rid of the inlet valve that refluxes.
Background technology
At present, the inlet valve in the existing jet mixing system, its movement parts that is used to control reinforced open and close is electromagnetic valve valve rod/and spool of driving of relevant follower/or valve plate.That electromagnetic valve gets is electric, during dead electricity, Flow of Goods and Materials is blocked/opened to stem movement/and drive relevant follower and drive spool/valve plate motion with this.This class switching device has the following disadvantages:
Electromagnetic valve get electric, when feeding pipe is unobstructed, stop up as the jet body export pipeline, form the liquid that refluxes and can enter in feeding pipe even the feed bin.
2. because the displacement movement of spool/valve plate is easy to solid material be brought into/scraped among spool/valve plate and the valve body, spool/valve plate motion is obstructed, causes the inlet valve open and close malfunctioning.
3. in some particular surroundingss, mix, cause circuit or electrical equipment to lose efficacy easily, or guarantee that with very high cost it is safe in utilization as inflammable, explosive, high burn into water dust.
Summary of the invention
The utility model purpose is the problem that exists at above-mentioned inlet valve structural shape, design a kind of simple in structure, with low cost, reliability is high, and can get rid of the new structure of backflow.Inlet valve is made up of valve body (1), ball sealer (2), bolt (3), feed pipe (4) and discharge nozzle (5) as shown in drawings.
The technical scheme that its technical matters that solves the utility model adopts is: feed pipe (4) upper end links with feed bin (not drawing among the figure), and lower end and valve body (1) link; Discharge nozzle (5) upper end links with valve body (1), and lower end and jet pipeline (not drawing among the figure) link; Communicate with each other with the duct that feed pipe (4) and discharge nozzle (5) connect mutually respectively in the valve body (1), and communicate with the water conservancy diversion duct (1-1) on right side; There is the tapped bore of a bigger hole and a hold-down bolt (3) on right side, water conservancy diversion duct (1-1), and the following side bottom non-central location in bigger hole has overflow duct (1-2); The external diameter of bolt (3) is a screw thread, and end face has the overflow duct (3-1) of non-single circle, links up mutually with water conservancy diversion duct (1-1); Bolt (3) is limited to ball sealer (2) between the right output port outside and overflow duct (3-1) left side in water conservancy diversion duct (1-1) after screwing in tapped bore.Its principle of work is: under the suction function that jet produces, ball sealer (2) is blocked the right output port of water conservancy diversion duct (1-1), and material is sucked out from feed pipe (4), enter discharge nozzle (5) by valve body (1) enters the jet pipeline again and mix with jet; Therebetween, stop up as the jet body export pipeline, then jet body turns to and enters discharge nozzle (5), form and reflux, at this moment, the negative pressure pop-off causes ball sealer (2) to get loose automatically, reflux and discharge by water conservancy diversion duct (1-1) and overflow duct (3-1) and overflow duct (1-2), salvage stores can be removed by overflow duct (1-2).Under the condition of no jet, ball sealer (2) is in free movement state, and material can not be inhaled into.
The beneficial effects of the utility model are, can be when the negative pressure of utilizing jet to produce be controlled the open and close of feed, and the backflow safety that will form in the time of will stopping up because of the jet body export pipeline effectively gets rid of, prevents that backflow enters charge pipe even feed bin.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the elevation profile constructional drawing of the utility model embodiment.
The specific embodiment
Inlet valve is made up of valve body (1), ball sealer (2), bolt (3), feed pipe (4) and discharge nozzle (5) as shown in drawings.Feed pipe (4) upper end links with feed bin (not drawing among the figure), and lower end and valve body (1) link; Discharge nozzle (5) upper end links with valve body (1), and lower end and jet pipeline (not drawing among the figure) link.The duct that connects feed pipe (4) in the valve body (1) is positioned at the top and angled the communicating in the duct that connects discharge nozzle (5), and communicates with the water conservancy diversion duct (1-1) on right side.There is the tapped bore of a bigger hole and a hold-down bolt (3) on right side, water conservancy diversion duct (1-1), and the following side bottom non-central location in bigger hole has overflow duct (1-2).The external diameter of bolt (3) is a screw thread, and end face has the overflow duct (3-1) of non-single circle, links up mutually with water conservancy diversion duct (1-1); Bolt (3) is limited to ball sealer (2) between the right output port outside and overflow duct (3-1) side in water conservancy diversion duct (1-1) after screwing in tapped bore.Water conservancy diversion duct (1-1) and overflow duct (3-1) and overflow duct (1-2) are lower than the outside port in the duct that connects feed pipe (4).
