Abstract
The utility model provides a low-cost hydraulic balance device. The low-cost hydraulic balance device comprises a box. The box is provided with a liquid inlet and a liquid outlet. The liquid inlet is communicated with an outer pipe network. A balance weight valve is arranged in the box and is a hollow box, and the outside of the balance weight valve can cover the liquid outlet completely. A cavity in the balance weight valve is communicated with a hydrargyrum box outside the box through a hose, and hydrargyrum in the hydrargyrum box can flow into the balance weight valve. The box is provided with an opening through which the balance weight valve can stretch out. The low-cost hydraulic balance device has the advantages of being simple in structure, convenient to maintain, low in machining cost and high in production efficiency.
Description
Technical field
The utility model relates to a kind of low cost hydraulic equilibrium device.
Background technique
In the water systems such as central heat supply in existing technology (cold), usually need hydraulic equilibrium device, as a part for whole pipe network, reduce its cost and will make the cost of whole pipe network decline.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of low cost hydraulic equilibrium device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: low cost hydraulic equilibrium device, comprise casing, described casing has liquid entering hole and liquid outlet, described liquid entering hole is communicated with outside ductwork, in described casing, there is counterweight valve, described counterweight valve is hollow box, its external energy blocks described liquid outlet completely, cavity in described counterweight valve is communicated with a mercury case of described casing outside by flexible pipe, mercury in described mercury case can flow in described counterweight valve, has the opening stretching out for described counterweight valve on described casing.
Also comprise link plate, have the frame plate of multiple different heights on described link plate, described mercury case can be placed on described frame plate.
On described link plate, have scale, described frame plate is corresponding to described scale.
Described counterweight valve both sides have guide plate, have the groove that can hold described counterweight valve bi-side on described guide plate.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, have simple in structurely, easy to maintenance, processing cost is low, manufacturing efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure: 1 is casing; 2 is breeding valve; 3 is liquid outlet; 4 is flexible pipe; 5 is frame plate; 6 is scale link plate; 7 is mercury case.
Embodiment
As shown in the figure, the utility model provides a kind of low cost hydraulic equilibrium device, comprise casing 1, casing has liquid entering hole and liquid outlet 3, and liquid entering hole is communicated with outside ductwork, in casing 1, there is counterweight valve 2, counterweight valve 2 is hollow box, and its external energy blocks liquid outlet 3 completely, and the cavity in counterweight valve 2 is communicated with a mercury case 7 of casing outside by flexible pipe 4, mercury in mercury case 7 can flow in counterweight valve 2, has the opening stretching out for counterweight valve on casing.
Also comprise link plate 6, have the frame plate 5 of multiple different heights on link plate 6, mercury case 7 can be placed on frame plate 5.
On link plate 6, have scale, frame plate 5 is corresponding to scale.Different scales indicate this different counterweight amount.
The working procedure of this example: regulate the height of mercury case 7, the weight of counterweight valve is changed, thereby change counterweight valve at subsurface height, reach and regulate the effect of counterweight valve to liquid outlet screening area.Different water flow corresponding to screening area.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
