Description
Technical field
This utility model relates to field of petroleum machinery, particularly relates to one and surges relief valve.
Background technology
In oil exploitation process; every mouthful of well all must install a set of wellhead assembly; wellhead assembly is all made up of tubing head and (gas) tree of recovering the oil; wherein SSV is mainly used in well site safeguard protection under oil and gas leakage, the emergency situation such as catch fire; different according to the drive source used, it is divided into surge relief valve and Pneumatic safety valve two kinds.Relief valve is mainly made up of driver and valve member two parts.There is standard interface, it is simple to change, keep in repair.Safety hydraulic coupling of surging is turned on and off valve, by ambient pressure source to the hydraulic oil providing certain pressure in hydraulic cylinder, drives piston to move, and final drives valve rod and flashboard linear reciprocating motion.But steady not in existing relief valve operation process of surging, accuracy is not high.
Utility model content
For solving above-mentioned technical problem, this utility model provides one and surges relief valve, and stable drive is reliable, and valve opening and closing state is accurate.
This utility model solves the technical scheme is that one of its technical problem and surges relief valve, and it includes valve member and driver, and described valve member includes valve body, valve gap and valve rod;Described driver includes frame shell, is arranged on the underbeam below frame shell, is arranged on the upper beam above frame shell and action bars;It is provided with gland between described valve gap and valve rod;The lower end of described underbeam and valve gap are spirally connected and are set on gland;Described action bars and valve rod are spirally connected;On action bars and valve rod, a big spring and a little spring it is arranged with between described underbeam and upper beam;Described driver be fixed with hydraulic cylinder above through upper cover;Described hydraulic cylinder includes piston;Described piston is provided with push rod;It is provided with locking plate between lower section and the upper beam of piston;Steel ball is adopted to be connected between described locking plate and upper beam.
The top of described piston is positioned at the upstream position of hydraulic cylinder and is provided with hydraulic oil fill assembly.
The side of described frame shell is provided with multiple breathing plug screw.
Described action bars and gland control valve stroke.
The beneficial effects of the utility model: one of the present utility model is surged relief valve, is connected with steel ball between locking plate with upper beam so that in operating process, stable drive is reliable, quick and easy for installation;Adopt double-acting spring, be effectively increased the resilience force of spring, can safely and effectively block fluid or quickly open;Action bars and gland are effectively guaranteed the stroke of valve, make valve opening and closing state accurate.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of relief valve that surges of embodiment.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with drawings and Examples, this utility model being described in further detail, this embodiment is only used for explaining this utility model, protection domain of the present utility model is not constituted and limits.
Embodiment
Surging relief valve as it is shown in figure 1, present embodiments provide one, it includes valve member and driver, and described valve member includes valve body 1, valve gap 2 and valve rod 3;Described driver includes frame shell 4, is arranged on the underbeam 5 below frame shell 4, is arranged on the upper beam 6 above frame shell 4 and action bars 9;It is provided with gland 8 between described valve gap 2 and valve rod 3;The lower end of described underbeam 5 and valve gap 2 are spirally connected and are set on gland 8;Described action bars 9 is spirally connected with valve rod 3;On action bars 9 and valve rod 3, big spring 10 and a little spring 11 it is arranged with between described underbeam 5 and upper beam 6;Described driver be fixed with hydraulic cylinder 14 above through upper cover 7;Described hydraulic cylinder 14 includes piston 15;Described piston 15 is provided with push rod 16;It is provided with locking plate 12 between lower section and the upper beam 6 of piston 15;Steel ball 13 is adopted to be connected between described locking plate 12 and upper beam 6;The top of described piston is positioned at the upstream position of hydraulic cylinder 14 and is provided with hydraulic oil fill assembly 17;The side of described frame shell 4 is provided with multiple breathing plug screw 18;Described action bars 9 and gland 8 control valve stroke.
The one of the present embodiment is surged relief valve, when the valve is closed, big spring and little spring in a state of nature, during valve opening, inject hydraulic oil by hydraulic oil fill assembly and enter hydraulic cylinder works chamber, hydraulic coupling promotes piston, and piston driving locking plate and upper beam move, and wherein locking plate and upper beam are connected by steel ball, action bars is thus driven to move down, compression big spring and little spring simultaneously, final driving valve rod moves downward, now valve opening;When removing hydraulic coupling, now big spring and little spring are in compressive state, have elastic force upwards, drive and move on upper beam and piston, and big spring and little spring reset, and drive valve rod to move upward, now valve closing.
The one of the present embodiment is surged relief valve, is connected with steel ball between locking plate with upper beam so that in operating process, stable drive is reliable, quick and easy for installation;Adopt big spring and little spring double-acting spring, be effectively increased the resilience force of spring, can safely and effectively block fluid or quickly open;Action bars and gland are effectively guaranteed the stroke of valve, make valve opening and closing state accurate.
Above-described embodiment should not in any way limit this utility model, and the technical scheme that all employings are equal to replacement or the mode of equivalency transform obtains all falls within protection domain of the present utility model.
