Abstract
The running water pipe on the ground often has the phenomenon of frost killing or frost crack in winter, which brings a lot of inconvenience to the production and life, and is not solved in the past years. The utility model provides a device preventing bursting of the water pipe by freezing, which solves the problem better. The device uses a purpose-made ball valve to arrange on the pipeline instead of the conventional break valve, and the ball valve can make the outdoor water pipe become open web or reduce the water level in the pipe in winter to make the air temperature in the water pipe and the air temperature outside the pipe in balance. Adopting the method, the utility model does not need to increase the investment, and has convenient installation, high durability and good effect.
Description
The utility model relates to water pipe anti-freezing and split technical field, what relate generally to is that a kind of water pipe anti-freezing splits device.
At present, tap water mostly is equipped with in rural area, vast city, and this has brought a lot of convenience for undoubtedly everybody productive life.But; one to winter; particularly the water pipe installed out of doors of the north often has and freezes to death or the phenomenon of bursting by freezing; especially rural area; the peasant is in order to feed the convenient mostly open air plant water pipe in institute of flushing to domestic animal; arrive severe winter one; the water pipe that is exposed to ground is often freezed to death; even bursting by freezing; brought inconvenience to users, water pipe is freezed to death winter or the problem of bursting by freezing in order to solve, and existing means to prevent freezing commonly used is to install ways such as linen-cotton topping or thickening tube wall additional to come antifreeze outside water pipe; but antifreezing effect is not obvious, and has increased financial burden to the user.
The purpose of this utility model promptly produces thus, proposes a kind of reasonable in design, and low price can prevent that antipriming pipe is freezed to death winter or the water pipe anti-freezing of bursting by freezing phenomenon splits device.
For achieving the above object, the utility model is achieved through the following technical solutions: it is to install a special ball valve on the pipeline of buried water pipe additional, this ball valve is by valve body, valve shaft, ball valve core and hollow flange sieve bolt constitute, the ball valve core is to support and the location by two hollow flange sieve bolts, have on the ball valve core long arc shape groove and and water-guiding hole on the ball valve core become T-shaped, the groove upper end is vertical with ball valve core water-guiding hole center line plane, the lower end is dropped on the central vertical line of ball valve core upper ball valve axle allocating slot, the first side of ball valve is opened a spillway hole, be fixed with anti-pollution valve on the spillway hole, be provided with alignment pin in the middle of the valve shaft, on the valve head neck, open-∮ 1/4 groove or ∮ 1/4 horse race hole.
The utility model structure design is simple, repacking convenience, low price, durable in use.Because it installs a special ball valve (original stop valve is removed) additional on the pipeline of buried water pipe, this special ball valve is different with social general ball valve, its valve body internal cavity is bigger, valve is by two hollow flange sieve bolts location, and two hollow flange sieve bolts and ball valve core contact position have O-ring seal to set off.Locate to have an arc groove for 90 ° in ball core water-guiding hole side, the central axis plane of an end and water-guiding hole is vertical, the central axis facade of the other end and water-guiding hole vertical (on the perpendicular bisector of ball core bottom).A side of valve head is opened a little spillway hole on ball valve body, install an anti-pollution valve on the hole additional, peace one alignment pin is opened-90 ° of arc grooves (or hole) at the valve head neck on valve shaft, the alignment pin on the valve shaft can only be in this arc groove (or hole) about 90 ° of activities.During like this to severe winter, as long as 90 ° of the valve shaft handle dextrorotation of drawing ground, the water-guiding hole on the ball valve core just in time becomes 90 ° of T-shaped to join with water-guiding hole (hollow flange sieve bolt) on the ball valve body to close water channel.At this moment exist the water of (vertical tube) in the water pipe of right side (preferably water nozzle to be opened through the arc groove of opening on the ball valve core, increase air pressure) slowly ooze in the cavity that slides into spheroid, after amassing completely, water in the cavity will back down the anti-pollution valve that is located on the valve body, current and flow to sewer by conduit in spillway hole drains into the reservoir of valve body bottom.Thereby prevented that effectively water pipe from freezing to death winter and the bursting by freezing phenomenon, guaranteed the safe water of productive life.
The utility model has following accompanying drawing:
Accompanying drawing 1 splits schematic diagram of device for the utility model water pipe anti-freezing
Accompanying drawing 2 cuts open figure for the special ball valve master of the utility model
Accompanying drawing 3 is the special ball valve core cut-away view of the utility model
Accompanying drawing 4 is the anti-pollution valve scheme of installation of the utility model
Accompanying drawing 5 is the utility model valve shaft positioning of rotating schematic diagram
In conjunction with the accompanying drawings, to as follows by embodiment of the present utility model:
As shown in the figure: the utility model is a special ball valve 3, and it is installed between water inlet pipe 1 water meter 2 and the upright water pipe 5, is provided with reservoir 4 in the bottom of special ball valve 3, is provided with gutter 6 (as shown in Figure 1) on reservoir 4.Special ball valve 3 is mainly by ball valve body 7, hollow flange sieve bolt 8, ball valve axle 9 anti-pollution valve 10 and ball valve core 11 are formed (as shown in Figure 2), ball valve core 11 is to support and be positioned in the cavity 14 in the ball valve body 7 by two hollow flange sieve bolts 8, studs with wear-resistant seal circle 18 in the contact site of two hollow flange sieve bolts 8 and ball valve core 11.Have an arc groove 12 on the ball valve core 11, its with ball valve body 7 in 13 one-tenths of water-guiding holes T-shaped (as shown in Figure 3), the center line plane of the water-guiding hole 13 on groove 12 upper ends and the ball valve core 11 is vertical, the bottom is dropped on the central vertical line of ball valve axle 9 allocating slots on the ball valve core 11, ball valve body 7 is provided with spillway hole 15, is provided with anti-pollution valve 10 (as shown in Figure 4) at spillway hole 15 positions.Ball valve axle 9 is connected as a single entity with ball valve core 11, itself and ball valve body 7 are fixedly connected by mother valve head sieve 17, contact site at ball valve body 7 and ball valve axle 9 is provided with annular water seal 19, on valve ball axle 9, be provided with the alignment pin 16 (as shown in Figure 5) that is used to make ball valve core 11 location, on the valve head neck, have a ∮ 1/4 groove or ∮ 1/4 horse race hole 20 (as shown in Figure 5).The course of work of utility model is as follows: during normal water supply, ball valve axle 9 left-handed 90 °, alignment pin 16 just in time bumps on the left side wall of valve head neck groove 20, current are by water inlet pipe 1, water meter 2 enters special ball valve 3, flows out for the normal life water from upright water pipe 5 then; As severe winter, 90 ° of ball valve axle 9 dextrorotation, alignment pin 16 bumps again on the right side wall of valve head neck groove, and ball valve core 11 just in time intersects with 8 one-tenth " ten " words of hollow flange sieve bolt at ball valve body 7 two ends, and feed water flow is cut off.At this moment the current on ball valve right side (water of vertical tube internal memory) slowly ooze in the cavity 14 that slides into ball valve body 7 through the arc groove of opening on ball valve core 11 12, in the long-pending reservoir 4 of anti-pollution valve 10 below spillway hole 15 flows to valve body that backs down to back pressure increase current to a certain degree on the valve body of water in the valve cavity 14, enter sewer by gutter 6 again.At this moment be exposed at and become state on an empty stomach in the ground water pipe, reach the purpose of the dead or bursting by freezing of water pipe anti-freezing.
