A kind ofly be used for the electromagnetic valve of paunch flusher and use the paunch flusher of this electromagnetic valve to be described further of the present utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the main pseudosection of the structural representation of a kind of electromagnetic valve that is used for paunch flusher of the present utility model.
Fig. 2 is to use the structural representation of the paunch flusher of this electromagnetic valve.
The specific embodiment
Referring to Fig. 1, electromagnetic valve described in the utility model comprise valve body, solenoid 1, iron core 2, back-moving spring 3, valve body is divided into upper valve body 7, middle valve body 8, following valve body 9, upper valve body 7 utilizes with following valve body 9 and is bolted on the middle valve body 8, have liquid outlet 21 and inlet opening 22 on the infra valve body 9, communicate in liquid outlet 21 and the inlet opening 22 infra valve bodies 9, the diameter of liquid outlet 21 and inlet opening 22 is the 7-10 millimeter, utilizes pipe joint 23 and pipeline to connect.Solenoid 1 is installed in the container of being made up of coil box 19 and lid 20, and utilization is bolted on the upper valve body 7.One end of back-moving spring 3 withstands on the end face of iron core 2, the other end withstands on the middle valve body 8 relative with iron core 2 end faces, the center of back-moving spring 3 is with plunger 4, the axis of plunger 4 parallels or overlaps with the axis of solenoid 1, one end of iron core 2 is connected with an end of plunger 4, the external diameter of plunger 4 is that liquid sealing cooperates with the contact surface of valve body, and the sealing member sealing is adopted in the gap in the while between valve body 8 and the plunger 4.The other end of plunger 4 is connected with sealing-plug 5, and sealing-plug 5 matches with liquid outlet 21 on the following valve body 9, and the periphery of liquid outlet 21 is the boss shape, and the height of boss is 3 millimeter, and the circumference wall thickness of boss is 2 millimeter.For avoiding resting on food debris on electromagnetic valve liquid outlet 21 limits to closing the influence of electromagnetic valve, the end face that sealing-plug 5 matches with liquid outlet 21 on the following valve body 9 can be designed to protruding sphere shape, the diameter of sealing-plug 5 is greater than the outer of the peripheral boss of liquid outlet 21, adopts bonding form to be fixed on an end of plunger 4 usually.The thickness of sealing-plug 5 is the 5-10 millimeter, and the material of sealing-plug 5 can adopt the moderate elastomeric material of soft poly-peace fat or other elasticity and rigidity to make.Owing to strengthened the thickness of sealing-plug 5, the elasticity of sealing-plug 5 is greatly strengthened, this has just been avoided resting on food debris on electromagnetic valve liquid outlet 21 limits to closing the influence of electromagnetic valve.
When the solenoid 1 of electromagnetic valve is in off-position, one end withstands on the end face of iron core 2, the other end withstand in back-moving spring 3 on the valve body 8 make the sealing-plug 5 that is connected plunger 4 other ends break away from liquid outlets 21, liquid outlet 21 and inlet opening 22 on the following valve body 9 are in on-state, can pass electromagnetic valve by materials such as gastric juice of extracting out in patient's stomach and food debriss.When the solenoid 1 of electromagnetic valve is in "on" position, iron core 2 overcomes the elastic force effect of back-moving spring 3 under the effect of electromagnetic field, the plunger 4 that promotion is connected iron core 2 one ends along in plunger hole on the valve body 8 move, the sealing-plug 5 that is connected plunger 4 other ends is matched with liquid outlet 21 on the following valve body 9, and the liquid outlet 21 on the valve body 9 is closed down.
Because the external diameter of plunger 4 is that liquid sealing cooperates with the contact surface of middle valve body 8, the sealing member sealing is adopted in gap simultaneously between valve body 8 and the plunger 4, gap during material such as gastric juice and food debris can not pass between valve body 8 and the plunger 4 makes back-moving spring 3 can not be subjected to the erosion of gastric juice and the influence of food debris adhesion.
On middle valve body 8 lubricating cup 5 is installed, lubricating cup 6 is connected by the stage casing of pipeline with plunger 4, is used for lubricated plunger 4.For preventing the erosion of materials such as gastric juice and food debris, middle valve body 8 and plunger 4 should adopt stainless steel material to make, and iron core 2 can adopt with being connected of plunger 4 and be threaded, and perhaps adopt to be welded to connect.
As seen from Figure 2, use the paunch flusher of electromagnetic valve, comprise gastric intubation 10, micro pump 11, vacuum pump 12, solution bottle 13 and electric apparatus control apparatus, and three electromagnetic valves 15 that are used for paunch flusher, 16,17 and two two-position two-way solenoid valves 14,14 ', the feed tube of micro pump 11 is connected with the clear water water source, the drain pipe of micro pump 11 is connected with the feed tube of electromagnetic valve 15, the drain pipe of electromagnetic valve 15 is connected with the feed tube of gastric intubation 6 and electromagnetic valve 16 by pipeline and tee pipe coupling, the drain pipe of electromagnetic valve 16 is connected with the bottom of solution bottle 13 and the feed tube of electromagnetic valve 17 by pipeline and tee pipe coupling, the top of solution bottle 13 by pipeline and tee pipe coupling respectively with two two-position two-way solenoid valves 14,14 ' be connected, two-position two-way solenoid valve 14 is connected with pressure-regulating valve 18 with vacuum pump 12 respectively by pipeline and tee pipe coupling, two-position two-way solenoid valve 14 ' be connected with vacuum pump 12 by pipeline.
Earlier gastric intubation 10 is inserted in patient's the stomach when using paunch flusher, utilize pressure-regulating valve 18 that vacuum pump 12 is adjusted to suitable force value, start vacuum pump 12 by electric apparatus control apparatus, be in off-position with seasonal electromagnetic valve 16, two-position two-way solenoid valve 14 is in "on" position, the pipeline at electromagnetic valve 16 and two-position two-way solenoid valve 14 two ends is communicated, make two electromagnetic valves 15,17 are in "on" position, two-position two-way solenoid valve 14 ' be in off-position, make two electromagnetic valves 15,17 and the pipeline at two-position two-way solenoid valve 14 ' two ends disconnect, two-position two-way solenoid valve 14 ' pipeline and ambient atmosphere connect, so under vacuum pump 12 and atmospheric effect, a certain amount of gastric juice and food debris are pumped down in the solution bottle 13 by electromagnetic valve 16 in patient's stomach.Start micro pump 11 by electric apparatus control apparatus subsequently, make electromagnetic valve 15 be in off-position, be in "on" position with seasonal electromagnetic valve 16, the pipeline at electromagnetic valve 15 two ends is communicated, the pipeline at electromagnetic valve 16 two ends disconnects, so under the effect of micro pump 11, a certain amount of clear water is injected into by electromagnetic valve 15 in patient's the stomach, and gastric juice in patient's stomach and food debris are diluted.
Meanwhile, make electromagnetic valve 16 be in "on" position, two-position two-way solenoid valve 14 is in off-position, the pipeline at electromagnetic valve 16 and two-position two-way solenoid valve 14 two ends is disconnected, the pipeline of two-position two-way solenoid valve 14 and ambient atmosphere are connected, make electromagnetic valve 17 be in off-position, two-position two-way solenoid valve 14 ' be in "on" position, the pipeline at electromagnetic valve 17 and two-position two-way solenoid valve 14 ' two ends is communicated, two-position two-way solenoid valve 14 ' pipeline and ambient atmosphere disconnect, so, under the effect of vacuum pump 12, ambient atmos makes the gastric juice and the food debris that are pumped down in the solution bottle 13 discharge paunch flushers through the pipeline of solution bottle 13 bottoms by electromagnetic valve 17 by two-position two-way solenoid valve 14 ' be pressed into solution bottle 13.Gastric juice and food debris in solution bottle 13 are discharged from, and inject a certain amount of clear water in patient's stomach after, restart above-mentioned circulation again.
