Abstract

The utility model relates to an antifreezing water saving valve. In the utility model, a flange plate whose center is provided with a hole is sealed and is fixed on the lower side of a cylinder-shaped cylinder body; a connecting pipe spout is welded and is sealed in the hole; a valve cover whose upper end is fixed with a support bracket is fixed above the cylinder-shaped cylinder body; the center of the support bracket is processed with a threaded hole, and a valve rod whose upper half part is provided with screw threads is screwed in the threaded hole of the support bracket; the upper end head of the valve rod is made into a square shape, and the valve rod penetrates through the valve cover; the lower end of the valve rod forms a taper shape which is matched with the connecting pipe spout, or a rubber stopper is fixed on the lower end of the valve rod; a piston which is matched with the inner diameter of the cylinder body is fixed on the upper part of the lower end head of the valve rod. The utility model has the advantages of simple structure, convenient use, and water resource saving.

Description

Water-saving frostbite valve

The utility model relates to a kind of anti-freezing economical valve.

At present, water tap at the northern China outdoor use, after water intaking uses up, must the water in the above part of running water pipe of frozen soil layer in time be bled off, freezing water tap or pipe in order to avoid freeze, perhaps again during water, iced obstruction because of tap water pipe line and got not water outlet, method commonly used is, on the tap water pipe line near the frozen soil layer bottom of water tap a valve is installed, after having got water and closing water tap, rotate above-mentioned valve, at this moment this valve is cutting off when tap water pipe line comes water, and this valve water in the pipe at water tap place is bled off (certain, as meanwhile will to open the running water pipe tap).This valve design waste water resource that prevents that tap water from freezing, particularly on railway, water bolt anti-freezing economical is a unsolved difficult problem on it, an aperture is opened on the top of last water bolt in the station that has, and on the train during water, aperture leaks simultaneously, aperture continues to leak after closing the water bolt, until the water in tens meters long pipelines has been leaked, every day, the water bolt was missed about seven tons in water in vain on each, caused the significant wastage of tap water.

The purpose of this utility model is to improve the shortcoming of prior art and a kind of anti-freezing economical valve is provided, and this valve both can prevent that tap water from freezing, and tap water is run off in vain, caused waste.

The purpose of this utility model is achieved in that it is flange of following sealing and fixing at a tubular cylinder body, the central punch of flange, and internal thread or external screw thread, upper end are arranged is the pressure inlet of bell to lower end of seal welding in the hole; Upper fixed one valve gap of tubular cylinder body, a support is fixed in the upper end of valve gap, the center of support is processed with screwed hole, the threaded valve rod of the first half screws in the screwed hole of support, and its termination is made square, so that rotate with the spanner clamping, valve rod passes valve gap, its lower end is for the taper that is complementary with pressure inlet or fix a circular rubber stopper, and a piston that is complementary with cylinder diameter is fixed on lower end top.

During use, this anti-freezing economical valve is fixed on the running water pipe below the frozen soil layer by a union, its position is between the outer pipeline valve of water tap and tap water, when taking tap water, the valve rod of this anti-freezing economical valve is screwed to extreme lower position, so that the lower end of valve rod is blocked the mouth mouth of pressure inlet, open outer pipeline valve, tap water flows out by water tap, and water finishes, close water tap, close outer pipeline valve, open the valve of anti-freezing economical valve, and then open water tap, water tap just is drawn in the tubular cylinder body of the anti-freezing economical valve that backflows to the water among the tap water pipe line more than the frozen soil layer, store, when fetching water again, can repeat above-mentioned steps, the valve rod of anti-freezing economical valve is screwed to extreme lower position, tap water in the cylinder body is entered water supply pipe, open outer pipeline valve, tap water promptly flows out from tap, with finishing, repeat above-mentioned steps.

The utility model is simple in structure, and is easy to operate, and the conserve water resource is specially adapted to give on the railway locomotive, compartment to add water and uses.

Quoting embodiment below in conjunction with accompanying drawing is described below.

Embodiment

Bottom's screw 2 at a tubular cylinder body 1, nut 3, sealing ring 4 is fixed a flange 5, the central punch of flange, seal welding is fixed a lower end in the hole internal thread, the upper end is the pressure inlet 6 of bell, the top of cylinder body screw 7, nut 8 is fixed a valve gap 9, ∩ font support 10 of upper end welding of valve gap, the center of frame is processed with screwed hole, valve rod 11 first halves screw in the support screwed hole, and its termination is made square, valve rod passes valve gap, the taper that is complementary with the pressure inlet mouth is made in its lower end, screw thread is arranged at lower end top, by nut 12, pad 13 grips a rubber system piston 14, this anti-freezing economical valve is installed on the following tap water pipe line 15 of frozen soil layer, and an end of tap water pipe line is to be in the above water tap 16 of frozen soil layer, and the other end is to be in the outer pipeline valve 17 that the following tap water of frozen soil layer comes water.
