Description
Technical field
The utility model relates to a kind of valve, more precisely is a kind of steam high temperature cooling cylinder of lubricated valve screw rod for a long time of getting rid of.
Background technique
The history of human existing centuries of application to valve, that uses till today mainly contains stop valve, gate valve, butterfly valve and ball valve etc. always; And the seal ring requisite lifelong accessory that always is exactly any valve.Gap sealing between the rotation of particularly static valve gap and valve rod (sealing of living), and the various valves that are sealed in HTHP, its adjustment, to change seal ring just more frequent.Though world today's new and high technology is fast-developing; Just promoting aspect the material of seal ring also; And aspect valve design, implement to get rid of used seal ring or improve the seal ring Environmental Conditions and alleviate the operating force of valve and avoid the excellent process of high temperature erosion.
Summary of the invention
The purpose of the utility model is to provide the damage of the isolated high temperature of a kind of cold water circuit mode to valve accessories, and with the heavy physical principle of oily light-water in condensed water with seal oil between the screw thread of rotation, guarantee the durable in use of high-temperature high pressure valve.
In order to achieve the above object; The solution that the utility model is taked is: the totally-enclosed valve oil immersion of a kind of HTHP screw rod cooling cylinder; It comprises cooling cylinder main body; Be provided with inner bag in the main body cover, be equipped with the oil sealing cylinder of under shed in the inner bag, the center of sealing on the oil sealing cylinder is through the fixing welding of switch connecting rod; Be provided with the oil storage cylinder of upper and lower opening in the oil sealing cylinder, running through the switch connecting rod in the oil storage cylinder, the switch connecting rod the higher authorities be connected with valve rod, and following is joined with the work of valve rod core dish internal thread by screw thread and is connected; Cooling cylinder top is provided with coolant outlet, and the below is provided with cooling water intake, and cooling water circulates outside the tank; Cooling cylinder upper flange is connected by screw with valve gap, and lower flange is fixedly connected with closed cylinder by screw.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, valve rod, 2, bonnet flange, 3, cooling cylinder upper flange, 4, the valve gap screw, 5, coolant outlet; 6, switch connecting rod, 7, oil storage cylinder, 8, lubricant oil, 9, the oil sealing cylinder, 10, cooling cylinder inner bag; 11, condensate water level line, 12, cooling cylinder main body cover, 13, cooling water intake, 14, valve rod core dish internal thread; 15, closed cylinder screw, 16, cooling cylinder lower flange, 17, valve rod core dish, 18, closed cylinder.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done description again.
Referring to Fig. 1; The oil immersion screw rod cooling cylinder of the totally-enclosed valve of a kind of HTHP; Comprise cooling cylinder main body cover 12, the top of main body cover 12 is provided with coolant outlet 5, and the bottom of main body cover 12 is provided with cooling water intake 13; Be equipped with cooling cylinder inner bag 10 within the main body cover 12, cooling water is in the peripheral circulation of inner bag 10; Be provided with oil sealing cylinder 9 in the cooling cylinder inner bag 10; Be provided with oil storage cylinder 7 in the oil sealing cylinder 9; Running through switch connecting rod 6 in the oil storage cylinder 7, the higher authorities of switch connecting rod 6 are connected with valve rod 1, and following of switch connecting rod 6 joined with the internal thread work of valve rod core dish 14 and be connected; Fill lubricant oil 8 in the internal upper part of oil sealing cylinder 9 and the oil storage cylinder 7, condensed water 11 is under the lubricant oil 8 all the time; The flange 3 that is provided with suitable for reading of cooling cylinder main body cover 12 is fixedly connected with bonnet flange 2 by valve gap screw 4; The end opening of cooling cylinder main body cover 12 is equipped with cooling cylinder lower flange 16 and is fixedly connected with closed cylinder 18 by closed cylinder screw 15.
Referring to Fig. 1, the inner chamber autocondensation water water line of described oil sealing cylinder 9 must be irritated sufficient lubricant oil more than 11 with within the oil storage cylinder 7, must not have air to exist.
Referring to Fig. 1, described oil immersion screw rod cooling cylinder main body must must not be inverted installation by the figure construction.
Referring to Fig. 1; The working principle of this cylinder is summarized as follows: in the process that valve is opened or closed; Switch connecting rod 6 and oil sealing cylinder 9 operation up and down along with the rotation of valve rod core dish internal thread 14; But because of enough height of oil storage cylinder 7 and enough degree of depth of oil sealing cylinder 9 can not overflow outside the lip of oil sealing cylinder 9 lubricant oil 8 all the time, Here it is with the heavy physical principle of oily light-water, guaranteed that the screw thread that is in water central authorities for a long time is able to permanent lubricated and cooling.
