Abstract
The invention relates to a method for mounting and dismounting a breathing type safety valve. The method for mounting and dismounting the breathing type safety valve comprises the following steps that 1), the breathing type safety valve is placed inversely, and a valve cap is fixed; 2), a valve body and the valve cap are separated away from the action of spring force; 3), the valve body is rotated forwardly or inversely to mount or dismount the safety valve. According to the method for mounting and dismounting the breathing type safety valve, mounting and dismounting are convenient, time and labor are saved, and a threaded pair can be prevented from being pulled and even burnt.
Description
Technical field
The invention belongs to Assembly of the parts technical field, relate to a kind of assembly and disassembly methods of the stainless steel screw thread pair with initial tension of spring, relate in particular to a kind of assembly and disassembly methods of breathing relief valve.
Background technology
Novel breathing relief valve (shown in Figure 1) is the parts on tank car, is mainly made up of valve body, bonnet, flap and spring.Valve body and bonnet material are stainless steel, and valve body and bonnet, in the time of composition safety valve, are threaded connection (shown in Figure 2), have during this time Compress Spring, make valve body and bonnet in the time of installation and removal, be subject to the effect of spring force.Mainly there is following shortcoming in existing dismounting breathing relief valve:
Breathing relief valve is just put, and bonnet is installed or pulled down to fixed valve body just or despining bonnet,, now, due to the effect of spring force, makes the screw thread pair between valve body and bonnet stressed, easily causes screw thread pair to pull, even burn.
Summary of the invention
In order to solve the above-mentioned technical problem existing in background technology, the invention provides a kind of easy accessibility, time saving and energy saving and can avoid screw thread pair to pull even the assembly and disassembly methods of the breathing relief valve of burn.
Technical solution of the present invention is: the invention provides a kind of assembly and disassembly methods of breathing relief valve, its special character is: the assembly and disassembly methods of described breathing relief valve comprises the following steps:
1) breathing relief valve is inverted and bonnet is fixed;
2) make to depart between valve body and bonnet the effect of spring force;
3) positive rotation valve body or despining valve body are realized the installation or removal to safety valve.
Above-mentioned steps 2) specific implementation be:
2.1) flap is pressed down;
2.2) flap Compress Spring and make flap and valve body depart from;
2.3) between valve body and bonnet, depart from the effect of spring force.
Advantage of the present invention is:
The assembly and disassembly methods of breathing relief valve provided by the present invention, to adopt reverse thinking, originally upright safety valve is inverted, the in the situation that of fixing bonnet, flap is pressed down to flap Compress Spring, make flap depart from valve body, thereby make not to be subject between valve body and bonnet the effect of spring force, at this moment positive and negative rotary valve, installs or pulls down bonnet.Now, due to dead spring, the screw thread pair between valve body and bonnet is not stressed, avoid screw thread pair to pull, even burn, the present invention adopts reverse thinking to overcome the inconvenience of current traditional dismounting, its method has convenient operation, easy accessibility, the beneficial effect such as time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of breathing relief valve;
Fig. 2 is the structure for amplifying schematic diagram of A part in Fig. 1;
Wherein:
1-valve body; 2-bonnet; 3-spring; 4-flap.
The specific embodiment
In conjunction with existing breathing relief valve structural representation, the invention provides a kind of assembly and disassembly methods to breathing relief valve, the method comprises the following steps:
1) breathing relief valve is inverted and bonnet 2 is fixed;
2) make between valve body 1 and bonnet 2 to depart from the effect of spring 3 power:
2.1) flap 4 is pressed down;
2.2) flap 4 Compress Springs 3 flap 4 and valve body 1 are departed from;
2.3) between valve body 1 and bonnet 2, depart from the effect of spring 3 power.
3) positive rotation valve body 1 or despining valve body 1 are realized the installation or removal to safety valve.
First the present invention puts breathing relief valve upside down, fixing bonnet 2, uses a kind of device to depress flap 4, flap 4 Compress Springs 3, make flap 4 depart from valve body 1, thereby make not to be subject between valve body 1 and bonnet 2 effect (also can with the power of the letting out mode of being commonly used in assembling field) of spring 3 power, at this moment positive and negative rotation bonnet 2, installs or pulls down bonnet 2 now, due to dead spring 3, screw thread pair between valve body 1 and bonnet 2 is not stressed, avoided screw thread pair to pull, even burn.
Claims (2)
1. an assembly and disassembly methods for breathing relief valve, is characterized in that: the assembly and disassembly methods of described breathing relief valve comprises the following steps:
1) breathing relief valve is inverted and bonnet is fixed;
2) make to depart between valve body and bonnet the effect of spring force;
3) positive rotation valve body or despining valve body are realized the installation or removal to safety valve.
2. the assembly and disassembly methods of breathing relief valve according to claim 1, is characterized in that: described step 2) specific implementation be:
2.1) flap is pressed down;
2.2) flap Compress Spring and make flap and valve body depart from;
2.3) between valve body and bonnet, depart from the effect of spring force.
