Abstract
The utility model relates to a high-strength non-leakage valve, composed of an upper valve body, a lower valve body, a screw rod, double movable joint rods, pistons, a valve cover, a sealant disk, a sealant ring and a hand wheel, wherein the pistons and the sealant disk on the upper part of the pistons are fixed between the double movable joint rods; the upper end of the double movable joint rods is connected with the screw rod; the lower end of the double movable joint rods is connected with the valve cover to form a sealed body; the pistons and the sealant disk are matched with the upper valve body; the sealant ring is fixed at the closed point of the lower valve body; the hand wheel is fixed on the upper end of the screw rod. Owing to the adoption of sealing principles of piston motion and the sealing structure of linked on-off, tightness is good in order to meet requirements of high temperature, high pressure and different fluid media.
Description
The utility model relates to a kind of valve, particularly a kind of high strength Leakless valve.
At present, traditional valve generally all adopts the stuffing seal arrangement, still, this device can't avoid various flowing mediums race, emit, weeping, cause waste live to pollute.Existing totally-enclosed Leakless valve) patent No. (ZL92204912.2) has adopted back-off virgin rubber bowl structure device, good seal performance, but back-off glue bowl is aging cracked easily, is difficult to especially be suitable in high temperature and high pressure environment, exists significantly not enough.
The purpose of this utility model is to overcome the deficiency of stuffing sealing structure unit and back-off round rubber bowl constructional device valve in the background technique, a kind of high strength Leakless valve is provided, better to reach sealability, Applicable scope is more extensive, particularly better at high temperature, condition of high voltage lower seal performance, more reliable purpose.
The purpose of this utility model is achieved in that the high strength Leakless valve mainly by upper valve body, following valve body, and screw rod, dual-active connector rod, piston, valve gap, sealer dish, O-ring seal and handwheel are formed.The sealer dish of piston and piston upper end is fixed on dual-active connector rod position intermediate, the sealer dish is located at the piston upper end, be connected with screw rod by dual-active connector rod upper end, dual-active connector rod lower end is connected with valve gap, form seal, piston and sealer dish cooperate with upper valve body, and O-ring seal is fixed on down valve body and closes the place, and handwheel is fixed on the screw rod upper end.
The utility model is owing to take piston motion sealing principle and open-shut linkage sealing configuration, and good seal performance is rational in infrastructure, to adapt to high temperature, condition of high voltage, and, adopt unlike material to make seal according to the requirement of different fluid ambient condition, can form series product.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation.
Among the figure: valve body, 2-upper valve body, 3-screw rod, 4-dual-active connector rod, 5-piston, 6-valve gap, 7-sealer dish, 8-O-ring seal, 9-handwheel under the 1-.
The high strength Leakless valve is mainly by following valve body 1, upper valve body 2, screw rod 3, dual-active connector rod 4, piston 5, valve gap 6, sealer dish 7, O-ring seal 8 and handwheel 9 are formed, sealer dish 7 is in the middle of piston 5 is fixed on dual-active connector rod 4, sealer dish 7 is located at piston 5 upper ends, dual-active connector rod 4 lower ends connect valve gap 6, be installed in the upper valve body 2, interlock effect by handwheel 9 and screw rod 3, drive piston 5, sealer dish 7, valve gap 6 moves up and down, O-ring seal is fixed on down the close port place of valve body 1, and upper valve body 2 is combined into a complete high strength Leakless valve door by flange or screw thread and following valve body 1.
During use, turn handwheel 9 moves downward by screw rod 3, and valve gap 6 is closely withheld on O-ring seal 8, makes valve be in closed condition; When turn handwheel 9, when moving upward by screw rod 3, valve open is full of flowing medium in the whole valve body, because the multi-stage sealed effect of piston 5 and sealer dish 7, prevent the leakage that valve may occur in opening process: when valve was opened fully, sealer dish 7 moved upward to the place, dead point, compresses airtight with upper valve body 2 upper port planes, reach and do not have the purpose of leakage fully, piston 5 and upper valve body 2 can be according to the different fluid media, and service condition is chosen corresponding material.To adapt to different usage requirements.
Claims (3)
1 one kinds of high strength Leakless valves, by upper valve body, following valve body, screw rod, the dual-active connector rod, piston, valve gap, the sealer dish, O-ring seal and handwheel are formed, it is characterized in that: the sealer dish (7) of piston (5) and piston (5) upper end is fixed in the middle of the dual-active connector rod (4), dual-active connector rod (4) upper end is connected with screw rod (3), dual-active connector rod (4) lower end is connected with valve gap (6), form seal, piston (5) and sealer dish (7) cooperate with upper valve body (2) inner wall sealing, O-ring seal (8) is entrenched in down the close port place of valve body (1), following valve body (1) is connected with upper valve body (2), and handwheel (9) is fixed on screw rod (3) upper end.
2. high strength Leakless valve according to claim 1 is characterized in that valve gap (6) withholds on O-ring seal (8).
