Abstract
The utility model is a water theft proof device which is used together with the water meter and is characterized in that: the utility model comprises a shell that is with water inlet and outlet, a gravity sealing object which is used to seal inlet water and which is positioned in the water inlet. The utility model is with easy to apply and is with simple structure low cost. The utility model realizes the functions of opposite sealing for water leakage and negative sealing for close due to the application of gravity and the operation is smooth and reliable. The utility model will not be put out of work due to the wearing of parts and components and the water pipe is leakage proof. The utility model is with long life span and can be manufactured to form an integration with the water meter or matched with existing water meter in series. The utility model can be connected to the inlet end and the outlet end of the water meter.
Description
Technical field
The utility model relates to water control device, specifically a kind of apparatus preventing water robbing that is used with water meter.
Background technology
Because the present water meter of the metering discharge of generally using, its trickle current to the water clock generation do not react, thereby can not carry out the discharge metering, and if when artificially water meter oppositely being installed, water meter produces the discharge reversing and reaches metering.People have established some at these problem meters and have solved the device of this class problem, as the patent No. is 200320128584.8 the antitheft water droplet table that leaks, under the effect of permanent magnet the suction-combining force, isolated Inlet and outlet water with piston valve, this valve must reach certain positive pressure difference just can be opened by current, has stoped passing through of minimum current.But its structure is complicated, and can reach iron impurity in the planar water after the long-term use of magnetic part, and it is not closed completely.And for example the patent No. is the anti-theft water meter of 94229193.X, realizes anti-stolen water by the valve that return to end of band spring, but spring can fatigue aging and lose anti-stealing water function.The patent No. is that the antitheft hydromagnetic control of the antiseep valve that 00256987.6 the watermeter of preventing water burglary and the patent No. are 00232296.X all is that structure is complicated, causes its performance unreliable.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the reliable apparatus preventing water robbing that is used with water meter.
The technical solution of the utility model is: this apparatus preventing water robbing seals water inlet by the housing that intake-outlet is arranged and being used to of installing in water inlet gravity shutoff object constitutes.
Gravity shutoff object is that an end is connected on the housing, and the other end is the movable end of opening and closing.This movable end can be multiple geometric configuration, as cover plate shape, ball shape, cone shape etc., as long as can block water inlet.
Gravity shutoff object cooperates with a guide piece, can be up and down can the opening and closing water inlet.This movable gravity shutoff object can be multiple geometric configuration, as cylindrical shape, ball shape, cone shape etc., as long as can block water inlet.
Apparatus preventing water robbing of the present utility model row simple in structure, easy, low cost of manufacture.Since be by gravity be used for realize that forward is airtight and leak and reversed closed obstructed function, make it reliable, can or not produce water pipe weeping, long service life because of reasons such as parts wear cause work malfunctioning.This device can directly be made one with water meter, also can connect with existing water meter individually to be used (must do tamper with the junction of water meter and drive processing), and this device can be connected to the water inlet end or the water side of water meter.
Description of drawings
Fig. 1 is the structural representation of one of apparatus preventing water robbing example of the present utility model;
Fig. 2 is the structural representation of one of apparatus preventing water robbing example of the present utility model;
Among the figure, 1-housing, 2-gravity tapered piston (gravity shutoff object), 3-piston guide cover (guide piece), 4-piston relief hole, 5-apopore, 6-gravity valve gap, 7-hinge axis, 8-water meter.
Embodiment
Embodiment 1:
As shown in Figure 1, apparatus preventing water robbing of the present utility model is by being made up of the housing 1 of intake-outlet and the gravity tapered piston of installing in water inlet 2 and piston guide cover 3.On the piston guide cover 3 apopore 5 is arranged, piston guide is overlapped 3 tops piston relief hole 4.
Working condition is:
1, when the water swivel of the association water side that this device of connection connects with water meter was closed, the pressure in this device was zero, and its gravity piston falls to sealing water inlet by self gravitation.
2, when the water swivel of artificially desiring to make this device and water meter association water side carries out the water clock stolen water with trickle flow, since open gravity piston institute must current strength more than or equal to the current strength of water meter operate as normal, so the current strength of trickle current generation can not be opened gravity piston.And when current strength greatly to can open gravity piston the time, water meter has also carried out normal gage work.
Embodiment 2:
As shown in Figure 2, apparatus preventing water robbing of the present utility model is finished the water inlet sealing by the gravity valve gap and is opened.The gravity valve gap is that an end is connected on the housing, the other end is movable, can the opening and closing water inlet.
Working condition is:
1, when the water swivel of the association water side that this device of connection connects with water meter was closed, the pressure in this device was zero, and its gravity valve gap falls to sealing water inlet by self gravitation.
2, when the water swivel of artificially desiring to make this device and water meter association water side carries out the water clock stolen water with trickle flow, since open gravity valve gap institute must current strength more than or equal to the current strength of water meter operate as normal, so the current strength of trickle current generation can not be opened gravity piston.And it is big to opening the gravity valve gap to work as current strength, and water meter has also carried out normal gage work.
3, when artificially this device and water meter association oppositely being installed, because this device has the reverse checkvalve effect, reverse flow can not pass through, and water meter is not worked yet.
Claims (3)
1, the apparatus preventing water robbing that is used of a kind of and water meter is characterized in that the gravity shutoff object that is sealed water inlet in water inlet by the housing that intake-outlet is arranged and being used to of installing constitutes.
2, the apparatus preventing water robbing that is used of according to claim 1 and water meter is characterized in that gravity shutoff object is that an end is connected on the housing, and the other end is the movable end of opening and closing.
3, the apparatus preventing water robbing that is used of according to claim 1 and water meter is characterized in that gravity shutoff object cooperates with a guide piece.
