Abstract
The utility model relates to a frostproof water meter which is formed by that a through hole is opened at the central position of the bottom of the shell body of an ordinary water meter; the through hole is provided with a pressure limiting valve. After water at the inlet and the outlet of the water meter ice, water in the water meter ice; when the volume expands, a conical valve plug which is arranged in the pressure limiting valve is pushed, springs are compressed, and the water in the water meter is discharged through a drain hole which is arranged on a valve body; consequently, pressure in the water meter is reduced to achieve the purpose of preventing the water meter from frosting and damage.
Description
The utility model relates to a kind of Anti-freezing water meter, is to open a through hole at light water watch shell bottom centre position, in the through hole pressure limiting valve is housed and constitutes.
In the area that arranged ice period, the thing of freezing the one's water breaks table happens occasionally, and severe cold area is even more serious.Therefore, bring very big loss for every year water supply department and user.Existing water meter is limit because of its structure, is difficult to prevent that water meter from freezing brokenly.
The purpose of this utility model is to avoid existing water meter weak point, and a kind of Anti-freezing water meter is provided.
For reaching the technical measures that the utility model purpose takes be:
Opening a through hole at light water watch shell bottom centre position, adorn a pressure limiting valve in the through hole, is two holes, large and small concentric garden that diameter is different in the valve body of pressure limiting valve, and the surface of contact in hole, two concentric gardens is a table top.Be placed with cone-shaped valve plug in the hole, garden with one heart, the internal diameter in cone-shaped valve plug external diameter and big hole, garden with one heart is for movingly; One blind hole is arranged in the cone-shaped valve plug; Pressure spring is housed in the blind hole, on the corresponding valve body in cone-shaped valve plug conical surface part bottom, has osculum; At valve body one end the adjustment nut is housed, one breeder tube is arranged at the nut center.
Osculum on valve body, minimum is one, is preferably three, three osculums are 120 ° each other.
Behind the water freezing that water meter is imported and exported, the water of water meter inside is because of the volumetric expansion of freezing, thereby cause that the table internal pressure increases, when reaching certain pressure, the promotion cone-shaped valve plug moves, the water of length of spring compressed water meter bottom is just discharged from osculum, the water meter internal pressure is reduced, thereby reach the purpose that prevents that water meter from freezing brokenly.
The utility model advantage compared with prior art is: owing to loaded onto pressure limiting valve on common water meter, when rated pressure, be closed, water in water meter is because of the volumetric expansion of freezing, the table internal pressure increases, and pressure limiting valve is opened, and discharges low amounts of water, the table internal pressure is decreased, can prevent that water meter from freezing brokenly.
Accompanying drawing is the utility model front portion cut-open view.
Be that the utility model is described in further detail for embodiment below with the accompanying drawing:
Open a screw at water meter 1 housing bottom center, valve body 2 is by in the screw that is threaded in water meter 1 housing; In the valve body 2 two holes, concentric garden 3,4 that diameter is different; Cone-shaped valve plug 5 is contained in the hole, garden 4, has 6, three osculums of three osculums and be 120 ° each other on the valve body 2 of cone-shaped valve plug conical surface bottom correspondence partly.Bottom at cone-shaped valve plug 5 is a blind hole, and pressure spring 7 is housed in blind hole; At an end of valve body 2, by screw thread adjustment nut 8 is housed, a breeder tube 9 is arranged at the center of nut 8.
Claims (2)
1, a kind of Anti-freezing water meter comprises a common water meter, it is characterized in that: have a through hole in the housing bottom center of common water meter 1, a pressure limiting valve is housed in the through hole; In the valve body 2 of pressure limiting valve two holes, concentric garden 3,4 that diameter is different; In concentric hole, garden, be placed with cone-shaped valve plug 5 movingly; On the corresponding valve body 2 in the conical surface part bottom of cone-shaped valve plug 5, have osculum 6; One blind hole is arranged in the cone-shaped valve plug, be placed with pressure spring 7 in the blind hole; At valve body 2 one ends adjustment nut 8 is housed, a breeder tube 9 is arranged at the center of nut 8;
2, Anti-freezing water meter as claimed in claim 1 is characterized in that: described osculum 6 is minimum to be one, is preferably three, is mutually 120 ° between three holes.
