Description

The antifreeze compensation device of water pump head
Technical field
This utility model relates to pump technology field, especially a kind of antifreeze compensation device of water pump head.
Background technology
In known technical field, water pump is commonly applied to carry liquid or make fluid pressurization, and water pump is in use, needs Water pump head memory stores up a part of water, forms vacuum environment and just can work.And when water pump reaches the ring of subzero degree Celsius in temperature When using in border, the water in water pump head will freeze, and after freezing, the volume of water will expand increase and produce huge answering Power, and in order to discharge the stress of generation, ice cube will produce huge extruding force to position more weak on water pump head, thus Water pump head is made to rupture, it is impossible to use;The conventional mode arranging dewatering outlet on water pump, not only operates complexity, needs artificial root Carry out according to temperature situation manual waterproof, use inconvenience.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of water solving the problems referred to above The antifreeze compensation device of pump head.
This utility model solves its technical problem and be the technical scheme is that a kind of antifreeze compensation device of water pump head, bag Including water pump head body, water pump head body is provided with intake and outlet, water pump head body upper end is provided with for water filling Water filling port, on water filling port, dismountable connection has the tender filling hole cover for blocking water filling port, and this internal being provided with of water pump head has Elastic hollow seal plastic casing.
This utility model is further arranged to: the medial wall of water pump head body is provided with mounting post, and mounting post is provided with Clamping joint, hollow seal plastic casing lateral wall be provided with clamping joint with the use of installing hole, hollow seal plastic casing passes through Installing hole and clamping joint are detachably arranged on the medial wall of water pump body.
This utility model is further arranged to: hollow seal plastic casing shorter straight less than outlet of length Footpath.
This utility model is further arranged to: hollow seal plastic casing is that polyethylene terephthalate plastics are made.
The beneficial effects of the utility model are: simple in construction, with low cost, can effectively be automatically prevented from water pump at low temperature ring Damage because water freezes under border.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
Preferred embodiment of the present utility model as Figure 1-5, a kind of antifreeze compensation device of water pump head, including water pump head Body 1, water pump head body 1 is provided with intake 2 and outlet 3, and water pump head body 1 upper end is provided with the water filling for water filling Mouth 4, on water filling port 4, dismountable connection has the tender filling hole cover 5 for blocking water filling port 4.When first use water pump, turn on note Water cap 5, injects water in water pump head body 1, forms vacuum environment, just can draw water in making water pump.
The resilient hollow seal plastic casing 6 of tool it is provided with in water pump head body 1.Hollow seal plastic casing 6 is arranged on water In pump head body 1, occupy the water holding space in water pump head body 1.Time below mercury dropped to 0 DEG C, in water pump head body 1 Water freeze, the not only volume of the water after icing can expand, and more can produce huge stress and carry out water of compaction pump head body 1.And it is empty Heart sealed plastic box 6 itself has elasticity, and its inner storage portion air, and air can shrink after catching a cold, Jin Erbing During block extruded hollow sealed plastic box 6, hollow seal plastic casing 6 a part of space of amortizing out is mended to the expansion of ice cube Repay.And when the stress that ice cube produces is increasing, the extruding force of ice cube continues hollow seal plastic casing 6 generation effect, make It is less that air in hollow seal plastic casing 6 compresses, thus more space of amortizing out expands to ice cube, so that ice Other positions of water pump head body 1 will not be extruded by block, and protecting water pump head body 1 will not damage because of the expansion of ice cube Bad.
The medial wall of water pump head body 1 is provided with mounting post 7, and mounting post 7 is provided with clamping joint 8, hollow seal plastics Box 6 lateral wall be provided with clamping joint 8 with the use of installing hole 9, hollow seal plastic casing 6 is by installing hole 9 and clamping joint 8 Being detachably arranged on the medial wall of water pump body 1, dismountable mounting means can facilitate the hollow seal of worse damage Plastic casing 6, makes hollow seal plastic casing 6 to use for a long time.
The length on one side that hollow seal plastic casing 6 is shorter, less than the diameter of outlet 3, thus can dismantle water Pump head body 1 and hollow seal plastic casing 6 is replaced.
Hollow seal plastic casing 6 is made for polyethylene terephthalate plastics, and polyethylene terephthalate is moulded Material can use in the environment below-30 DEG C.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people Member can carry out various change and amendment completely in the range of without departing from this utility model technological thought.This reality The content being not limited in description by novel technical scope, it is necessary to determine its technology according to right Property scope.
