A 90-degree rotatable safety valve body fixture

Abstract

The invention relates to a safety valve body clamp capable of rotating by 90 degrees, and belongs to the technical field of clamps. The safety valve body clamp comprises a base plate; a left side plate and a right side plate are arranged on the left side and the right side of the base plate respectively; a convex round block is arranged on the inner side face of the left side plate; a connecting bolt is arranged on the rear side of the upper portion of the right side plate in a passing manner; an elastic pin is fixed to the front side of the upper portion of the right side plate; a sleeve valve frame is arranged between the left side plate and the right side plate; a bottom through hole is formed in a bottom plate of the sleeve valve frame; a side through hole is formed in the left end face of the sleeve valve frame; a bolt bearing set is arranged on the left end face of the sleeve valve frame in a passing manner; and a first positioning hole and a second positioning hole matched with elastic pins are correspondingly formed in the bottom of the front side of the right side face of the sleeve valve frame and the upper portion of the rear side of the sleeve valve frame respectively. The bolt bearing set is adopted to support a safety valve body; the extending length of bearing bolts is adjustable; and the safety effect on a safety valve body is achieved. The matched connection relation of the convex round hole and the side through hole is adopted, supporting of the convex round block for the sleeve valve frame is ensured, and it is also ensured that the sleeve valve frame can freely rotate.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to a 90-degree rotatable safety valve body clamp. Background technique [0002] The safety valve is the opening and closing part in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it prevents the medium pressure in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. [0003] The safety valve is a three-way valve, one end of the safety valve is a threaded end, and the other two ends of the safety valve are flanges. When processing the flange of the safety valve, due to the irregular shape of the...

Problems solved by technology

[0003] The safety valve is a three-way valve, one end of the safety valve is a threaded end, and the other two ends of the safety valve are flanges. When processing the flange of the safety valve, due to the irregular shape of the safety valve, the two ends opposite to the flange There is no positioning reference, processing is difficult, and manufacturing accuracy is difficult to guarantee
