Abstract
The utility model belongs to the anti-cracking technical field of a liquid material transmission and distribution system and particularly relates to an anti-cracking device for a water container such as a water pump, a water meter, a valve and the like. The container is provided with a joint which is communicated with an inner cavity, the upper end of the joint is sequentially provided with a sealing gasket and a pressure safety disc from bottom to top, which can be clamped on the upper end face of the joint, and a hollow nut is screwed on the joint so as to seal and compress the pressure safety disc and the sealing gasket with the inner cavity of the container. The anti-cracking device has simple structure, low cost, simple production process and good anti-cracking effect and is applicable to anti-cracking popularization and application of the water container such as the water pump, the water meter, the valve and the like.
Description
Technical field:
The utility model belongs to the anti-bursting by freezing technical field of liquid material distributing system, refers in particular to a kind of anti-bursting by freezing devices of band water receptacle such as water pump, water meter, valve that can be used for.
Background technology:
In some comparatively cold areas, winter temperature is lower, and water meter, water pump, valve etc. are used for the easy freezing and expansion of device of liquid material transmission ﹠ distribution, and internal stress increases, and causes being damaged by frost, bursting by freezing, brings many inconvenience for people's productive life.Be damaged by frost for fear of water meter, water pump, valve etc., people have adopted certain methods to deal with, but all convenient inadequately.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, band water receptacle such as cost is low, manufacturing process simply can effectively prevent water pump, water meter, valve by the anti-bursting by freezing device of bursting by freezing.
The utility model is achieved in that
A kind of band water receptacle is prevented the bursting by freezing device, container is provided with the joint that communicates with inner chamber, upper end of joint is disposed with gasket seal and the pressure security sheet on the upper surface that may be stuck in joint from bottom to top, and the bore seal that is spun on the joint pressure security sheet and gasket seal and container with the nut of hollow compresses.
The afterbody of the nut of above-mentioned hollow is provided with toe-in and forms annular nib, and the annular nib on the nut contacts with the outer of pressure security sheet upper surface.
Above-mentioned gasket seal is a rubber sheet gasket.
Above-mentioned pressure security sheet is sheet glass or plastic sheet or sheet metal.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model is simple in structure, cost of production is low, technology is simple;
2, the utility model can effectively prevent band such as water pump, water meter, valve water receptacles under the environment of cold by bursting by freezing.
Description of drawings:
Fig. 1 is that embodiment 1 is installed in the user mode structural representation on the water pump;
Fig. 2 is the user mode structural representation that embodiment 2 installs on the water meter;
Fig. 3 is a cross-sectional view of the present utility model.
The specific embodiment:
With specific embodiment the utility model is further described below,
Embodiment 1: referring to Fig. 1,3:
Adopt water pump to make specific embodiment:
A kind of water pump is prevented the bursting by freezing device, the water storage cavity 50 of water pump is provided with the joint 40 that communicates with water storage cavity 50, joint 40 upper ends are disposed with gasket seal 30 and the pressure security sheet 20 on the upper surface that may be stuck in joint 40 from bottom to top, are spun on the joint 40 with the nut 10 of hollow pressure security sheet 20 and gasket seal 30 are compressed with water storage cavity 50 sealings.
The afterbody of the nut 10 of above-mentioned hollow is provided with toe-in and forms annular nib 101, and the annular nib 101 on the nut 10 contacts with the outer of pressure security sheet 20 upper surfaces.
Above-mentioned gasket seal 30 is a rubber sheet gasket.
Above-mentioned pressure security sheet 20 can be sheet glass or plastic sheet or sheet metal.
Operating principle is: under the weather conditions of cold, water in the water pump water storage cavity 50 is because the internal stress of freezing increases, internal stress can discharge from pressure security sheet 20 of the present utility model, prevented breaking of water storage cavity 50 casings, the gasket seal 30 that is arranged on pressure security sheet 20 belows can seal on the one hand effectively, on the other hand, prevent that also glass fragment from dropping in the water storage cavity 50, influences the water pump operate as normal.
Embodiment 2: referring to Fig. 2,3:
Adopt water meter to make specific embodiment:
A kind of water meter is prevented the bursting by freezing device, the water storage cavity 51 of water meter is provided with the joint 40 that communicates with water storage cavity 51, joint 40 upper ends are disposed with gasket seal 30 and the pressure security sheet 20 on the upper surface that may be stuck in joint 40 from bottom to top, are spun on the joint 40 with the nut 10 of hollow pressure security sheet 20 and gasket seal 30 are compressed with water storage cavity 51 sealings.
The afterbody of the nut 10 of above-mentioned hollow is provided with toe-in and forms annular nib 101, and the annular nib 101 on the nut 10 contacts with the outer of pressure security sheet 20 upper surfaces.
Above-mentioned gasket seal 30 is a rubber sheet gasket.
Above-mentioned pressure security sheet 20 can be sheet glass or plastic sheet or sheet metal.
Because water meter itself just is provided with glass window, then require the coefficient of expansion of pressure security sheet of the present utility model to be less than the coefficient of expansion of the glass of observation port.
Operating principle is: under the weather conditions of cold, water in the water meter water storage cavity 51 is because the internal stress of freezing increases, tend to freezing water meter, cause water meter not show phenomenon generations such as inaccurate, cause unnecessary trouble, after the utility model is set, the internal stress that increases can discharge from pressure security sheet 20 of the present utility model, prevented that water meter is damaged by frost, the gasket seal 30 that is arranged on pressure security sheet 20 tops can seal on the one hand effectively, on the other hand, prevent that also glass fragment from entering in the water storage cavity 51, influences the water meter operate as normal.
The utility model is simple in structure, and cost is low, can effectively prevent water pump, water meter, valve etc. under the environment of cold by bursting by freezing.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
