Abstract
The utility model relates to an outdoor antifreezing valve. The utility model is characterized in that the side face of the valve body is provided with an antifreezing device which is communicated with a valve chamber and is composed of a jet nozzle and a water recovery apparatus. Through the function of the jet nozzle, when the water supply is cut off and the valve is closed, the water stored in the water outlet pipe flows naturally into the water recovery apparatus to make no water in the pipe; when the valve is opened again, through the negative pressure produced by the jet nozzle, the water in the water recovery apparatus is brought into the jet nozzle and flows into the water outlet pipe. So after the valve is closed, the valve can be not frozen to break any longer. The valve has the advantages of good antifreezing effect, water saving, simple structure, convenient use and installation, firmness and durability.
Description
The utility model relates to a kind of valve, and the antifreezing valve especially for outdoor belongs to mechanical field.
At the extremely frigid zones of cold, the running water valve of outdoor application, very easily freezing, influence water, increase maintenance.For this reason, most methods that adopt " running water ", even valve is not closed tight all the year round, the long stream of water is more than, with prevent to freeze, bursting by freezing, cause the waste of water equally, valve opening is not smooth, and a kind of antifreezing valve is also arranged, adopt of the water emptying of two valve bodies with outlet pipe, its complex structure, part rapid wear in addition, antifreezing effect is bad.
The purpose of this utility model is the shortcoming and deficiency in order to overcome above-mentioned prior art just, and designs a kind of antifreeze outdoor antifreezing valve that can economize on water that gets final product, thereby can guarantee water, the water supply of extremely frigid zones.
The purpose of this utility model realizes by following technical proposal.
A kind of outdoor antifreezing valve, comprise valve body, valve pocket, valve rod, valve head, gland nut, water intake, water outlet and handwheel, it is characterized in that an anti-icer that communicates with valve pocket is arranged in the valve body side, it is made up of jet mouth and water recovery apparatus, jet mouth inner chamber two ends are had hemispheric small cylindrical inner chamber less than the cylindrical diameter in both sides and are formed by truncated cone and cylindrical rightabout tubaeform inner chamber and the middle upper portion formed, middle inner chamber lower vertical is communicated with the screwed return pipe in lower end, jet mouth outer end is that water outlet is connected with outlet pipe, the recovery tank of the sealing that water recovery apparatus is made up of loam cake and casing, suction valve, connecting rod, float, ball sealer is formed, return pipe stretches in the recovery tank, be threaded fixing by the lower end screw thread with the loam cake hole, returning pipe joint connects plastic tube in the case, and the ball sealer of suction valve is connected with float by connecting rod.
Wherein the recovery tank capacity is greater than outlet pipe water capacity.
Owing to take technique scheme to make the utility model compared with the prior art, have good freezing protection effect, water saving, it is simple in structure, advantage such as sturdy and durable is installed, easy to use.
Description of drawings:
Fig. 1 is the structural representation of outdoor antifreezing valve.
Below in conjunction with the accompanying drawing example the utility model technology is further specified:
Outdoor antifreezing valve, comprise valve body (1), valve pocket (2), valve rod (3), valve head (4), gland nut (5), water intake (6), water outlet (7) and handwheel (8), have one to communicate with valve body with valve pocket be the anti-icer of one in the valve body side, it is made up of jet mouth and water recovery apparatus, jet mouth inner chamber two ends are formed rightabout tubaeform inner chamber and middle upper portion by truncated cone (9) and cylindrical (10) and are had hemispheric and form less than the small cylindrical inner chamber (11) of the cylindrical diameter of both sides inner chamber, it can make into water by jet chew increase hydraulic pressure after, diffusion ejection rapidly, middle inner chamber lower vertical is communicated with the screwed return pipe in lower end (12), and it is that water outlet is connected with outlet pipe that jet is chewed the outer end; Water recovery apparatus is made up of recovery tank, suction valve (15), connecting rod (16), float (17) ball sealer (18) of the sealing that loam cake (13) and casing (14) are formed, return pipe stretches into the recovery tank bottom, be threaded fixing by the screw thread on the return pipe with the loam cake hole, return pipe connects plastic tube (19) in the case, the ball sealer of suction valve is connected with float by connecting rod, the capacity of recovery tank is greater than outlet pipe water capacity, guarantees that outlet pipe does not have water, in case bursting by freezing.
Working procedure: when opening valve, water enters valve pocket by water intake, because the effect of intake pressure, water penetrates water outlet rapidly and enters outlet pipe water supply, when throttle down by jet mouth inner chamber, the water of outlet pipe is chewed inner chamber along jet and is flowed in the water tank of water recovery apparatus naturally, along with the increase of water consumption, make float rising in the water tank, ball sealer is closed suction valve, because the recovery tank capacity is greater than intake pipe water amount, therefore can guarantee that water can be not excessive, guarantee no water in the outlet pipe simultaneously, when cold snap, valve can be by bursting by freezing, freeze, when opening valve once more, the water of water intake enters valve pocket again, at this moment, having produced negative pressure in the ejection of jet mouth brings the water in the recovery tank simultaneously into and penetrates, float for water tank descends, and ball sealer is opened suction valve, and air enters water tank.When cutting off the water throttle down, the water of outlet pipe falls water tank after rise again and does not have water, supplies water when opening valve like this, and during throttle down, outlet pipe does not have water, works and so forth, and valve can be not freezing again, and guaranteeing to supply water needs.
The utility model valve can be installed on the aqueduct that does not freeze layer, switching system and outlet pipe can be basseted, and is convenient to manipulate.
Valve of the present utility model also can be used for reaching antifreezing effect in the outdoor opening and closing device with the water similar liquid.
Claims (2)
