Abstract
An air cylinder and a valve comprising the air cylinder are designed in order to reduce the cost of high-temperature resistant valves. The air cylinder comprises a cylinder body (10) and a piston rod (11), and is characterized in that: the periphery of the piston rod outside the cylinder body is provided with a cooling structure. The valve comprises a valve body (20) and a valve rod (21), and is characterized by comprising one air cylinder, the cylinder body (10) of which is fixedly connected with the valve body (20) and the piston rod (11) of which is fixedly connected with the valve rod (21), and as mentioned above, the periphery of the piston rod outside the cylinder body of the air cylinder is provided with the cooling structure.
Description
Technical field
The utility model relates to valve and cylinder.
Background technique
In injection machine mould temperature control machine system, need to adopt the valve of high temperature resistant (180 ℃).The valve rod of present this valve is by solenoid actuated, and is relatively more expensive.If directly adopt existing cylinder to come actuate valve stem, then the airtight construction of cylinder is damaged by high temperature easily.
Summary of the invention
The purpose of this utility model provides a kind of resistant to elevated temperatures valve, its lower cost; The utility model also provides a kind of cylinder, to satisfy the needs of high temperature resistant valve.
The technical solution of the utility model is: cylinder is improved, and the piston rod periphery outside its cylinder body is provided with cooling structure.Then, with the valve rod of this kind air cylinder driven valve.That is:
A kind of cylinder comprises cylinder body and piston rod; It is characterized in that: the piston rod outer periphery outside its cylinder body is equipped with cooling structure.And:
A kind of valve comprises valve body and valve rod; It is characterized in that: a cylinder is arranged, and its cylinder body is fixed on valve body, and its piston rod is fixed on valve rod; The piston rod outer periphery of this cylinder outside its cylinder body is equipped with cooling structure.
The beneficial effects of the utility model: by such scheme and structure as can be known, cylinder of the present utility model can satisfy the needs of high temperature resistant valve.Its lower cost of valve of the present utility model.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is embodiment's a schematic representation.
Fig. 2 is embodiment's a sectional view.Wherein valve body 20 and valve rod 21 are not done to analyse and observe, and have omitted the hatching of piston rod 11.
Embodiment
As shown in the figure, a kind of cylinder comprises cylinder body 10 and piston rod 11; It is characterized in that: the piston rod outer periphery outside its cylinder body is equipped with cooling structure.
