Description
Technical field
The utility model relates to a kind of giver, especially relates to a kind of plunger type giver being mainly used in fumigant (as Celfume, vikane etc.) and spraying.
Background technology
Current quarantining treatment, employing fumigant insect killing, stifling killing mouse are common methods.Fumigant (as Celfume, vikane) major part is high poisonous gas, is generally store in steel cylinder.During use (as during to Inter-fumigation of Container Cargo), valve on steel cylinder need be connected grug transportation tube, and by the dedicated pins be connected on grug transportation tube, fumigating gas is injected internal container and carry out stifling dissipation operation, after stifling operation completes, fumigation medicament is still had to remain in grug transportation tube, residual medicament can be propagated in atmosphere, easily touch stifling operating personnel's skin or enter in human body by human respiratory tract, so not only waste medicament, and there is great personal safety and environmental pollution hidden danger.Not yet find the giver be suitable at present.
Summary of the invention
Main purpose of the present utility model is to provide can avoid residual fumigation medicament in grug transportation tube, saving medicament, a kind of plunger type giver that safety is good.
The utility model comprises water conservancy diversion inclined tube, nut cap, housing, return spring, plunger, handwheel, check valve and prop head;
Described nut cap is located at water conservancy diversion inclined tube rear end and is integrated with water conservancy diversion inclined tube, nut cap and housing forward end are spirally connected, plunger is arranged in housing, plunger is hollow plunger, plunger outer wall and inner walls seal and are slidably matched, return spring is located between housing Inner Front End and plunger front end, stopping means is provided with between housing rear end and plunger back-end, handwheel is located at plunger back-end and is spirally connected with plunger back-end, the check valve port of export and plunger back-end are spirally connected, check valve inlet end and prop head one end are spirally connected, the external grug transportation tube of the prop head other end.
Described housing is preferably cylinder shell, and the forward lumen of described housing is preferably conical internal cavity, can make play during plunger advancement buffering and better sealing function gradually like this.
The front and rear of described plunger outer wall is preferably equipped with sealing ring.
Described stopping means can be made up of stopper slot and limited screw, and described stopper slot is located at plunger back-end, and described limited screw is located at housing rear end, and limited screw front end is arranged in stopper slot; Described stopper slot is preferably annular recess.
Described plunger front bulkhead is preferably provided with air vent, and the direction of air vent can be rod radial air vent, and the quantity of air vent is preferably 4 and is radial equipartition setting.
Described check valve and prop head can select existing product.
Compared with the prior art, the beneficial effects of the utility model are as follows:
During use, prop head of the present utility model be connected with outside grug transportation tube one end, the grug transportation tube other end is connected with gas storage cylinder valve.Operator can carry out keying operation by direct hand-held giver.By the interaction of plunger, check valve, prop head and return spring, plunger in the housing between bilateral reciprocation complete the open and close function of giver.When the water conservancy diversion inclined tube of giver enters band disinfecting container (as container), under the effect of steel cylinder output pressure, described check valve is opened and is acted on plunger, plunger displacement is to housing forward end, the ventilation hole of plunger front end is in the vacuum zone of housing forward end inner chamber, and fumigant escapes and enter dispenser container by ventilation hole.When the water conservancy diversion inclined tube of giver departs from container, reaction force will move after making plunger, and the ventilation hole of plunger front end is airtight; The active force of plunger displacement also will act on check valve, and check valve is closed.Can require to open in time and closed fluid conveying pipe according to dispenser like this, avoid residual gas Release and dispersion in pipe conveying fluid, prevent leakage of medicament and waste.Effective raising safety and the feature of environmental protection.Operator greatly reduces working strength and increases work efficiency simultaneously.
