Description
Technical field
The utility model relates to a kind of parallel slide valve, especially a kind of hand liquid two moving parallel slide valves.
Background technique
In oil gas well wellhead assembly and various pass meeting valve sets; Use parallel slide valve in a large number; This initial approach to become a Buddhist believer is leaned on freely fitting between metal flashboard and the metal outbreak plane, and under the effect of medium, realizes sealing by seal gease, during sealing; Valve pocket bears line pressure, drives valve rod through rotating handwheel.In conventional gate valve series, the keying function of valve or implement to open and close by a kind of modes wherein such as manual, hydraulic transmission, Pneumatic Transmission, electric control equipments.Control type is single, sufficient power can not be provided or can not in case of emergency realize closure.
The model utility content
The utility model technical problem to be solved provides a kind of hand liquid two moving parallel slide valves.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of parallel slide valve, comprise valve body, handwheel, and it is characterized in that the valve body top is equipped with sheave, said sheave is provided with handle, and said handle is plugged on the said sheave; Said handle and valve body paper spare are provided with half nuts; Be plugged with locating stud on the said handle; Said handwheel downside is provided with oil cylinder cover; Said oil cylinder cover downside is provided with manual opening stem; Said manual opening stem downside is provided with piston; Said piston underside is provided with the oil cylinder that surges; The said oil cylinder downside that surges is provided with upper flange; Said upper flange downside is provided with the valve rod that surges; With said oil cylinder cover be that symmetrical position is provided with first fuel-intake connection with the valve body; Said fuel-intake connection downside is provided with connecting sleeve; Said connecting sleeve downside is provided with second fuel-intake connection.
The beneficial effect of the utility model is: under parallel slide valve can only the situation of single control, merged handle and oil supply system, made and on same valve, can adopt manual mode to implement the keying of gate valve, can adopt the mode of surging to implement gate valve again and open and close.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, also be provided with nut on the said half nuts and drive and the position label, in order to show the folding situation of said half nuts.
Further, said valve body downside is provided with valve seat; Said valve seat downside is provided with flashboard; Said flashboard downside is provided with lower flange; Said lower flange downside is provided with guide rod.
Description of drawings
Fig. 1 is the utility model schematic representation;
In the accompanying drawing, the list of parts of each label representative is following:
1, handle, 2, locating stud, 3, half nuts, 4, handwheel, 5, oil cylinder cover; 6, manual opening stem, 7, piston, 8, the oil cylinder that surges, 9, upper flange, 10, valve rod surges; 11, valve body, 12, valve seat, 13, flashboard, 14, lower flange, 15, guide rod; 16. sheave, 17, half nuts position label, 18, first fuel-intake connection, 19, connecting sleeve, 20, fuel-intake connection.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Of Fig. 1, upper flange 9 plays airtight effect with lower flange 14; Connecting sleeve 18 connection hand ovable valve stems 6 and piston 7; Guide rod 15 is under air-tight state, through moving up and down balance valve body internal pressure.
Cut off in the oil well hydraulic oil in the hydraulic pressure oil feed line and supply with, to make the hydraulic pressure charge oil pressure be zero and be in unloading condition.Removed handle 1; Manually clockwise rotate sheave 16 about 45 °; Cause movably half nuts 3 closures, depress handle 1 then, make locating stud insert positioning hole 2; Guarantee that half nuts 3 and valve body 11 are in the matching gap that configures, half nuts position label 17 can show opening and Chengdu of half nuts 3.Rotate handwheel 4 this moment, rotate, realize manual opening stem 6 or the straight line motion that rises or fall, through the valve rod 10 that surges that links together, the manual opening-closing function that flashboard 13 can be realized gate valve through half nuts 3.
Removed handle 1, manually rotated counterclockwise sheave 16 about 45 °, caused movably half nuts 3 to be opened, depressed handle 1 then, made locating stud 2 insert positioning holes, guaranteed that half nuts 3 and valve body 11 are in the disengaging configuration that configures.This moment hydraulic pressure oil feed line initiation pressure fuel feeding; The first oily joint 18 and second fuel-intake connection 20 through oil cylinder get into the oil cylinder 8 that surges; The charge oil pressure at oil cylinder piston 7 two ends is implemented pressure conversion control by hydraulic control system; Piston 7 is realized to-and-fro motion under the pressure difference effect of hydraulic oil, piston 7 drives hydraulic valve stem 10, flashboard 13 is accomplished switching motion.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
