Abstract: The present invention relates to a spring adjusting device and a valve assembly. The spring adjusting device comprises an adjusting screw rod, a spring and a spring seat which is located between the adjusting screw rod and the spring; a groove is arranged in the spring seat, which can contain an end part of one end of the adjusting screw rod, and is provided with a cylindrical side wall. The prevent invention can prevent the end part from being separated from the groove, the spring from being bent on the whole, and the overall working performance of the valve assembly can be improved.

Abstract: The present invention includes a sensing device, a bonnet located below the sensing device, a piston with a through hole, and a valve stem connected with the sensing device, and a penetrating part through the through hole wherein the sensing device drives the valve stem to drive the piston; an auxiliary spring is arranged between the bonnet and the piston; the penetrating part is longer than the depth of the through hole; and the valve stem is slidably coupled in piston. The disclosed valve can prevent the valve stem from transferring the force of the main spring to the piston, so as to avoid damaging the valve port, the valve stem and the piston due to a reason that the force of the main spring is too large.

Abstract: A valve assembly includes a sensing device, a main spring, a bonnet located below the sensing device, a piston with a through hole, and a valve stem connected with the sensing device and having a penetrating part through the through hole. The sensing device drives the valve stem to drive the piston. The valve assembly also includes an auxiliary spring arranged between the bonnet and the piston. The penetrating part is longer than the depth of the through hole and the valve stem is slidably coupled in piston. The valve assembly can prevent the valve stem from transferring the force of the main spring to the piston, so as to avoid damaging the valve port, the valve stem, and the piston when the force of the main spring is too large.
