Abstract
The utility model discloses a flat sealing ultralow-temperature safety valve. The flat sealing ultralow-temperature safety valve comprises a valve body, and the inside of the valve body is provided with a valve hole which penetrates the valve body, and a sealing gasket arranged inside the valve hole; the inside of the valve hole at one end of the sealing gasket is provided with a gas inlet liquid-state channel connector, and the other end of the sealing gasket is provided with a piston; the liquid outlet end of the valve body is provided with an adjusting screw; a spring is mounted between the piston and the adjusting screw; the portion of the valve body, which corresponds to the mounting position of the piston, is provided with a screw hole, and a positioning screw for preventing rotation of the piston is arranged inside the screw hole; the portion of the side surface of the piston, which corresponds to the screw, is provided with a bayonet; the sealing gasket and the valve body are sealed in a flat mode. According to the flat sealing ultralow-temperature safety valve, the sealing gasket achieves flat sealing and accordingly shortens the fully-open stroke and reduces the spring compression, so that the flat sealing ultralow-temperature safety valve is rapid and stable in pressure relief and prevents water steam or other impurities from entering a sealing port and further avoids leakage or damage.
Description
Technical field
The utility model relates to a kind of plane sealing ultralow temperature safety valve, and its operating temperature range is-200 DEG C～+ 100 DEG C.
Background technique
General safety valve of the same type in the market, the sealed mouth of employing is conical surface seal (as shown in Figure 1), and conical surface seal can make the standard-sized sheet stroke of valve strengthen, and amount of spring compression strengthens, and easily water inlet and foreign material of conical surface seal mouth, thereby causes leakage.
Summary of the invention
Cause the standard-sized sheet stroke of valve to strengthen in order to overcome when existing safety valve sealed mouth adopts conical surface seal, amount of spring compression strengthens, and conical surface seal mouth is water inlet and foreign material easily, thereby the shortcoming that causes leakage etc., the utility model provides a kind of plane sealing ultralow temperature safety valve that can effectively solve sealing face leakage problem.
The technical solution adopted in the utility model is:
A kind of plane sealing ultralow temperature safety valve, comprise valve body, in valve body, be provided with the valve opening that connects valve body, be arranged on the sealing gasket in valve opening, in the valve opening of one end of sealing gasket, be provided with the liquid channel interface of air inlet, the other end is provided with piston, the outlet end of described valve body is provided with adjusting screw, between piston and adjusting screw, be provided with spring, it is characterized in that: on described valve body, corresponding piston mounting point is provided with screw hole, in screw hole, be provided with the positioning screwn for preventing piston rotation, the position of the described corresponding positioning screwn of piston side face is provided with bayonet socket, the end of described positioning screwn is stuck in described bayonet socket, it between described sealing gasket and valve body, is plane sealing, on the valve opening of described sealing gasket below, be provided with step, on described step, be provided with projection, described protruding upper-end surface is plane and touches with sealing gasket, and the upper-end surface of the described liquid channel interface of air inlet flushes with described protruding upper-end surface.
Further, in described piston and adjusting screw, be respectively arranged with spring positioning table terrace.
Further, described valve body lower portion is provided with drain opening near a side at the liquid channel interface of air inlet position.
The beneficial effects of the utility model are embodied in: the sealing gasket of valve is plane sealing, sealed mouth is protruding form of nozzle, and the standard-sized sheet stroke of valve is diminished, and amount of spring compression reduces, safety valve pressure release is stablized fast, prevents that again water vapour or other foreign material from entering sealed mouth and causing leakage or damage.
