Abstract
The utility model discloses a low temperature angle formula stop valve for among air separation plant and low temperature pipeline, its main characteristic is that valve rod nut passes through the plane bearing and supports in the valve body to use the splint that only can up-and-down linear motion that establish on the valve rod to prevent the valve rod from doing the circular motion, when rotating valve rod nut through the hand wheel, the valve rod just can only do up-and-down linear motion just, in addition pack and adopt the extremely low fluoroplastics of coefficient of friction, and set up the fluoroplastics sealing washer on the valve clack, this kind of structure makes the operation laborsaving; secondly, the abrasion speed of the filler is reduced; thirdly, the sealing is durable, therefore, the utility model is a low-temperature angle stop valve with good sealing performance and use performance.
Description
The utility model relates to a kind of low temperature Angle Stop valves that air separation plant and cryogenic pipe control media Liu Liang And play on-off action that is used for.
The stop valve flap open and pass and aperture thereof are to realize by moving up and down of valve rod, and moving up and down of valve rod is to realize with the formed screw pair of internal thread that is fixed on the Stem Mut on the valve body by the outside thread on the valve rod.Therefore the motion of valve rod is a circular movement and straight-line synthetic.This structural feature is brought two problems: the one, and the resistance of stem movement is big, the operation effort; The 2nd, the rate of wear of the filler in the Stuffing box is very fast, causes easily leaking.
The purpose of this utility model provides a kind of rapid operation, the low temperature Angle Stop valves that the filler rate of wear is slow.
The design proposal that achieves the above object is that Stem Mut is bearing in the valve body by plane bearing, and handwheel is installed on the Stem Mut, and can be along being located at the clamping plate that the guide plate on the valve body moves up and down at setting-in on the valve rod.
Further illustrate detailed content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: the utility model structural drawing;
Fig. 2: A A partial sectional view.
The low temperature Angle Stop valves is made up of valve body 1, flap 2, valve rod 3, handwheel 4, Stem Mut 5 and Stuffing box.Wherein valve body 1 is fastened by upper valve body and following valve body and forms; Stuffing box is located at upper valve body, comprises packing cavity, filler 6, gland 7 and screw rod 8 that compresses and nut 9, can the oneself feel relieved in order to make gland 7, and screw rod 8 is hinged with valve body 1; The lower end of valve rod 3 connects with flap 2 by lock ring 10, and the lower end surface of flap 2 is provided with fluoroplastic seal ring 11 ， And glands on valve seat; Be located at the internal thread formation screw pair of the outside thread of valve rod 3 upper ends with Stem Mut 5, and Stem Mut 5 is bearing in the valve body 1 by plane bearing 12, handwheel 4 is installed on the Stem Mut 5 And can be along being located at the clamping plate 14 that the guide plate 13 on the valve body 1 moves up and down at setting-in on the valve rod 3, totally two on clamping plate 14, two notch Nei ， And that are inlaid in valve rod 3 are respectively tightened up by screw 15, and the breach that forms between two clamping plates 14 then closes with guide plate 13 ranks; Consider corrosion-resistant problem in order to reduce valve rod 3 with the frictional force ， And between the filler 6, the filler 6 of present embodiment adopts fluoroplastic.
The valve rod of said structure low temperature Angle Stop valves is only made straight line motion up and down, filler also only is subjected to the wearing and tearing of rectilinear direction, obviously its rate of wear will slow down greatly, support by plane bearing because of Stem Mut again, the friction factor of fluoroplastic filler is minimum again, pulls the Stem Mut rotation by handwheel and just is easy to.Therefore, the utility model rapid operation, the rate of wear is slow, and long service life is that a kind of sealing is durable, low temperature Angle Stop valves easy to use.
Claims (3)
1, a kind of low temperature Angle Stop valves, form by valve body, flap, valve rod, handwheel, Stem Mut and Stuffing box, it is characterized in that: Stem Mut 5 is bearing in the valve body 1 by plane bearing 12, handwheel 4 is installed in Stem Mut 5 Shang ， And can be along being located at the clamping plate 14 that the guide plate 13 on the valve body 1 moves up and down at setting-in on the valve rod 3.
2, low temperature Angle Stop valves according to claim 1 is characterized in that: the filler 6 in the Stuffing box adopts fluoroplastic.
3, low temperature Angle Stop valves according to claim 1 and 2, it is characterized in that: the lower end surface of flap 2 is provided with fluoroplastic seal ring 11.
