Abstract
The utility model provides a kind of ball valve with decompression function, comprise valve body, adpting flange, spool etc., the two ends of described valve body are provided with adpting flange, the inside of described valve body is provided with spool, the inside of described spool offers circulation passage, the lower end of described spool is provided with valve rod, the lower end of described valve rod is connected with switch handle, the upper end of described spool is provided with piston chamber, described piston chamber is provided with relief opening, the inside of described piston chamber is provided with pressure release piston, and described connecting rod is connected with the upper end of pressure release piston through piston chamber.The utility model adds decompression function, by the interaction of pressure release piston and stage clip, when making to reach certain high pressure in delivering pipe, the fluid in pipeline can be made to discharge from the relief opening of piston chamber and to carry out pressure release, not only reduce installation, dismounting difficulty, and substantially reduce the situation that the inner member of the high pressure in delivering pipe to ball valve causes damage.
Description
Technical field
The utility model relates to valve field, particularly relates to a kind of ball valve with decompression function.
Background technique
Along with the develop rapidly of science and technology, production technology and the product structure of ball valve are updated, present ball valve has become a kind of main valve class, be widely used in petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, the industries such as iron and steel, very important status is occupied in national economy, the open-shut device of ball valve is a spheroid, utilize spheroid around the object of the axis half-twist realization opening and closing of valve rod, easy and simple to handle laborsaving, only need very little moment of rotation, just can open or throttle down, there is compact structure, being easy to Operation and maintenance etc. repaiies a little, but in pipeline transport system, pressure in delivering pipe changes often, especially in high temperature transportation environment, the pressure increase in pipeline is made after liquid gasification, this causes certain potential safety hazard to pipeline, existing ways of addressing this issue installs Decompression valves on delivering pipe, this adds the quantity of the element in pipeline transport system undoubtedly, not only make to mount and dismount very complicated more, and increase workload and the maintenance expenses of pipeline transport system later period maintenance, and the limited pressure system that ball valve can bear, unduly high pressure can cause damage to the element of ball valve inside, thus shortens the working life of ball valve.
Summary of the invention
According to above technical problem, the utility model provides a kind of ball valve with decompression function, comprise valve body, adpting flange, spool, circulation passage, valve rod, switch handle, it is characterized in that: also comprise pressure release piston, connecting rod, piston chamber, punch holder, stage clip, die holder, relief opening, the two ends of described valve body are provided with adpting flange, the inside of described valve body is provided with spool, the inside of described spool offers circulation passage, the lower end of described spool is provided with valve rod, the lower end of described valve rod is connected with switch handle, the upper end of described spool is provided with piston chamber, described piston chamber is provided with relief opening, the inside of described piston chamber is provided with pressure release piston, described connecting rod is connected with the upper end of pressure release piston through piston chamber, the upper end that connecting rod is fixed on piston chamber is inserted in one end of described die holder, one end of described punch holder is inserted in connecting rod and is connected, the other end of described punch holder is connected with die holder by stage clip.
Described circulation passage is for falling " T " font through-hole structure.
The beneficial effects of the utility model are: the utility model improves on original ball valve, namely decompression function is added, by the interaction of pressure release piston and stage clip, when making to reach certain high pressure in delivering pipe, pressure release piston top is carried out pressure release to piston chamber upper end, high pressure in delivering pipe can make piston upwards, the connecting rod of piston upper end also moves up simultaneously, drive punch holder deflection compression press spring, thus make the fluid in pipeline carry out pressure release from the relief opening discharge of piston chamber, not only reduce the installation of the auxiliary element of pressure release class in delivering pipe, thus reduce installation, dismounting difficulty, reduce installation and maintenance cost, and substantially reduce the situation that the inner member of the high pressure in delivering pipe to ball valve causes damage, extend the working life of ball valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
According to Fig. 1, the utility model is further described:
As Fig. 1, valve body-1, adpting flange-2, spool-3, circulation passage-4, valve rod-5, switch handle-6, pressure release piston-7, connecting rod-8, piston chamber-9, punch holder-10, stage clip-11, die holder-12, relief opening-13.
Embodiment 1
The utility model comprises valve body 1, adpting flange 2, spool 3, circulation passage 4, valve rod 5, switch handle 6, pressure release piston 7, connecting rod 8, piston chamber 9, punch holder 10, stage clip 11, die holder 12, relief opening 13, first at the two ends of valve body 1, adpting flange 2 is installed during installation, then the circulation passage 4 of inverted T shape is offered in the inside of spool 3, again piston chamber 9 is arranged on the upper end of spool 3, piston chamber 9 offers relief opening 13, pressure release piston 7 is arranged on the inside of piston chamber 9, connecting rod 8 is connected with the upper end of pressure release piston 7 through piston chamber 9, then the upper end that connecting rod 8 is fixed on piston chamber 9 is inserted in one end of die holder 12, again connecting rod 8 is inserted in one end of punch holder 10 to connect, the other end is connected with die holder 12 by stage clip 11, the last inside then spool 3 being arranged on valve body 1, valve rod 5 is connected to the lower end of spool 3, switch handle 6 is arranged on the lower end of valve rod 5.
Embodiment 2
During use, rotary switch handle 6, valve rod 5 is with movable valve plug 3 to rotate, and makes horizontal channel and the pipeline communication of circulation passage 4, and at this moment fluid flows into valve body 1, valve body 1 is flowed out after circulation passage 4, when pressure increase in delivering pipe, the high pressure in delivering pipe can make pressure release piston 7 move upward, and the connecting rod 8 of pressure release piston 7 upper end also moves up simultaneously, drive punch holder 10 to deflect compression press spring 11, thus make the fluid in pipeline carry out pressure release from relief opening 13 discharge of piston chamber 9.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
