Description

Safety valve working handle

Technical Field

The utility model belongs to the technical field of a relief valve door class technique and specifically relates to a relief valve work handle.

Background

The conventional safety valve is automatically operated and automatically reset, but the safety valve needs to regularly detect whether the safety valve is normal in daily use, generally adopts a regular disassembly mode, or adopts a value exceeding a set pressure to detect whether the safety valve is disconnected, and similar detection modes take time and have low efficiency; and the case of relief valve also can be because of the problem that the adhesion appears in various factors, leads to the relief valve to reach the set pressure not take off under the accident situation, can adopt to make equipment stop work certainly, leads to production to stop, causes economic loss, for this reason, needs an auxiliary mode, can make relief valve detection and can artifical quick opening relief valve opening pressure under the accident situation.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art, and provides a safety valve working handle which comprises a handle body, wherein the handle body is an integral body consisting of an execution handle and a connecting handle, the execution handle is formed by cold forging a steel plate into a shape like a Chinese character '7', the center of the semi-circle head of the head part of the connecting handle is provided with a connecting hole, the lower end of the execution handle is provided with an auxiliary hole, and the middle position of the upper end surface of the connecting handle is provided with a convex circular arc; the safety valve can be manually opened when the safety valve reaches the set pressure in an accident state, and the safety valve can be quickly opened by quickly lifting and pulling up the handle after the condition that the valve core of the safety valve is prevented from being adhered and does not jump is eliminated; simple structure, practicality, delicacy, save material, energy-conservation, convenient operation, high quality.

In order to achieve the above purpose, the technical scheme of the utility model is that: a safety valve working handle comprises a handle body, wherein the handle body is an integral executing handle and a connecting handle which are formed by cold forging a steel plate into a shape like a Chinese character '7', a connecting hole is formed in the center of a semicircular head of the connecting handle, an auxiliary hole is formed in the lower end of the executing handle, and a convex circular arc is formed in the middle of the upper end face of the connecting handle.

Further, the included angle between the execution handle and the connecting handle is 100 degrees.

The lower end of the semicircular head is flush with the lower end face of the connecting handle, and the upper end of the semicircular head is higher than the upper end face of the connecting handle.

The utility model has the advantages that: the utility model makes the safety valve open pressure quickly; simple structure, practicality, delicacy, save material, energy-conservation, convenient operation, high quality.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: the handle comprises a handle body 1, an execution handle 2, a connecting handle 3, a semicircular head 4, a convex arc 5, a connecting hole 6 and an auxiliary hole 7.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

As shown in fig. 1, a safety valve working handle, comprises a handle body 1, wherein the handle body 1 is formed by cold forging a steel plate into a 7-shaped execution handle 2 and a connection handle 3 integrally, a connection hole 6 is formed in the center of a semi-circular head 4 at the head of the connection handle 3, an auxiliary hole 7 is formed at the lower end of the execution handle 2, and a convex circular arc 5 is formed in the middle of the upper end face of the connection handle 3, the handle body 1 is connected in a valve cap after a pin shaft penetrates into the connection hole 6, and the safety valve can be opened manually to check whether the safety valve is normal or not; the safety valve can be manually opened when the safety valve reaches the set pressure in an accident state, and the safety valve can be quickly opened by quickly lifting and pulling up the handle after the condition that the valve core of the safety valve is prevented from being adhered and does not jump is eliminated; simple structure, practicality, delicacy, save material, energy-conservation, convenient operation, high quality.

The included angle of the execution handle 2 and the connecting handle 3 is 100 degrees, which accords with the conventional angle of the palm and the arm of the human body and is beneficial to fast holding and opening.

The lower end of the semicircular head 4 is flush with the lower end face of the connecting handle 3, and the upper end of the semicircular head 4 is higher than the upper end face of the connecting handle 3.

Example of the implementation

The handle main body 1 is inserted into the connecting hole 6 by a pin shaft and fixed with the valve cap, and the safety valve can be opened manually to check whether the safety valve is normal or not; the safety valve can be manually opened when the safety valve reaches the set pressure in an accident state, and the safety valve can be quickly opened by quickly lifting and pulling up the handle after the condition that the valve core of the safety valve is prevented from being adhered and does not jump is eliminated; simple structure, practicality, delicacy, save material, energy-conservation, convenient operation, high quality.

In practical application, the convex circular arc 5 is a fulcrum, the execution handle 2 is a power arm, the valve core connected with the connecting hole 6 through the pin is a resistance arm, when detection is needed, the execution handle 2 is manually pressed inwards by the plate to swing by taking the convex circular arc 5 as a fulcrum angle, the other end of the convex circular arc 5 serving as the fulcrum is upwards opened with the valve core connected with the connecting hole 6 through the pin, and the effect of detecting whether the valve core of the safety valve is adhered or not is achieved.
