Description
Technical field
The utility model relates to a kind of defroster, the specifically a kind of and matching used tap-water pipe defrosting device of running water pipe.
Background technology
In the winter in the north, often freeze at the position, ground of running water pipe, and especially night, temperature was low, more easy freezing.Many defrosters have appearred on the market for this reason, a kind of " air pressing type tap-water pipe defrosting device " disclosed as Chinese patent CN2083596U, it is by pressure tank, valve rod, compositions such as the upper and lower piston that is connected with valve rod, plunger, water valve, metal tube, inflatable ball, shelves ball-collecting rack.This apparatus structure complexity, parts are many, and manufacturing cost is higher, is not easy to especially peasant household's use of unshared housing.
Summary of the invention
It is low that goal of the invention of the present utility model provides a kind of cost of production, simple in structure, the tap-water pipe defrosting device that defroster and running water pipe are used.
In order to realize the foregoing invention purpose, the utility model by the following technical solutions: a kind of tap-water pipe defrosting device comprises the air pressure cylindrical shell, handle, what be connected with handle places valve rod in the air pressure cylindrical shell, the joint that an end is connected with running water pipe, the plunger of pressurization usefulness.Its structural feature is, the upper end of this pressure tank is connected with upper end cover, and the lower end is connected with bottom end cover, and bottom end cover is provided with steam vent; This valve rod is stepped, and piston is equipped with in its bottom; This valve pin hole that plunger middle part is provided with steam vent, the lower end is provided with to communicate with the bottom end cover steam vent, plunger is plugged on the valve; This valve is positioned on the valve base; On this valve base upper press cover is housed, there is sealing ring the upper press cover lower end, under the sealing ring lower cover is arranged, and this lower cover is twisted with the lower cover nut and is connected on the valve; This joint base is connected with the bottom end cover of pressure tank, connects with the joint threaded one end.
Owing to adopted technique scheme, the utility model and tap water water pipe are used, and the push-and-pull valve rod is given pressurization in the running water pipe, lean on this pressure that water level is reduced to overhead below 80 centimeters, can prevent effectively that just running water pipe from freezing.Compared with prior art, of the present utility model simple in structure, parts are few, low cost of manufacture.Use, installation, maintenance convenience, rapid operation is convenient to especially peasant household's use of unshared housing.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
The utility model tap-water pipe defrosting device is by air pressure cylindrical shell 4, handle 1, valve rod 3, joint base 9, valve base 8, plunger 12 compositions such as grade.Referring to accompanying drawing 1, air pressure cylindrical shell 4 is a rigid canister, and its upper end is threaded with upper end cover 21, and the lower end is threaded with bottom end cover 7.The middle part of bottom end cover 7 is provided with steam vent 19.This valve rod 3 is stepped, places in the air pressure cylindrical shell 4.For rapid operation, be with spring 2 on the top of valve rod 3, expose outside air pressure cylindrical shell 4, wherein the upper end of valve rod 3 is connected with handle 1, and piston is equipped with in the bottom of valve rod 3, and piston is made up of last plain cushion 5, following plain cushion 6 and rubber seal 20.The bottom of valve rod 3 is fastening with nut and piston.Drawing handle 1, valve rod 3 moves up and down in air pressure cylindrical shell 4.The plunger 12 of the usefulness of calming the anger is plugged on the valve 16, and the middle part of plunger 12 is provided with steam vent 15, and the lower end is provided with the valve pin hole 22 that communicates with bottom end cover steam vent 19.This valve 16 is positioned on the valve base 8.On this valve base 8 upper press cover 18 is housed, upper press cover 18 lower ends are provided with the rubber seal 10 that seals, and rubber seal has lower cover 17 10 times, and these lower cover 17 usefulness lower cover nuts 11 are twisted and are connected on the valve 16 the lower end connection nut 14 of valve 16.Joint base 9 is threaded with the bottom end cover 7 of air pressure cylindrical shell 4.The top of joint 13 is positioned at joint base 9, one ends and is threaded with joint base 9, and the other end is connected with running water pipe.Valve base 8 is positioned at joint, is threaded with the bottom end cover 7 of air pressure cylindrical shell 4.
During use, joint 13 twisted with running water pipe connect, push-and-pull valve rod 3, air enters running water pipe along bottom end cover steam vent 19 to plunger steam vent 22, action with pull valve rod 3 back and forth increases air pressure, the water level of the running water pipe after the pressurization is reduced to apart from about 80 centimeters of below grounds, and then running water pipe can not freeze, realize goal of the invention.
