And current discharge valve all is not suitable for the protective clothing of taking the safety cover, and after venom got into discharge valve, can cause the threat to user's life safety.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects that the existing exhaust valve has higher expiratory resistance and lower expiratory resistance, and the expiratory resistance and the opening force are not adjustable to ensure that a user breathes unsmoothly, and designs the exhaust device on demand, which ensures that the exhaust volume is kept moderate when the exhaust device is used on site, ensures that the user breathes comfortably and ensures that the user obtains better user experience.
In order to achieve the aim, the demand exhaust device applied to the protective clothing is characterized by comprising an adjusting cover, wherein a cavity is arranged in the adjusting cover, the bottom of the adjusting cover is open, and an exhaust port is arranged on the side surface of the adjusting cover; the valve body is provided with a through hole in the middle, the top of the valve body is connected with the bottom of the adjusting cover, and the side face of the lower end of the valve body is provided with an air inlet; the valve block is arranged at the joint of the valve body and the adjusting cover and used for blocking the through hole of the valve body and the cavity of the adjusting cover; the tower spring is arranged in the cavity of the adjusting cover, one end of the tower spring abuts against the top of the adjusting cover, and the other end of the tower spring abuts against the valve plate; and the protective suit is connected with the middle part of the valve body.
Preferably, the inner wall of the adjusting cover is provided with threads, and the outer wall of the valve body is provided with threads matched with the threads.
Preferably, the valve plate is connected with the valve body through a plastic buckle.
Preferably, the side surface of the adjusting cover is provided with an adjusting screw which passes through the adjusting cover and abuts against the thread of the outer wall of the valve body.
Preferably, the tower spring is provided with a taper.
Compared with the prior art, the utility model has the advantages that: when the protective clothing with the exhaust valve is used by a user, the exhaust airflow is not too large or too small but moderate, so that the user does not have obvious breathing difference caused by wearing the protective clothing and without wearing a device at ordinary times, the wearer is more comfortable when breathing, and the exhaust is controlled within a reasonable range.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a cross-sectional view of the overall construction of the present invention;
FIG. 3 is an exploded view of the present invention;
in the figure: 1. the valve comprises an adjusting cover 2, an exhaust port 3, a valve body 4, a sealing ring 5, a valve plate 6, a tower spring 7, a protective clothing 8, a plastic buckle 9 and an adjusting screw.
Detailed Description
The present invention is further described below in conjunction with the following drawings, the structure and principle of which will be apparent to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1-3, the utility model relates to an on-demand exhaust device applied to protective clothing, which comprises an adjusting cover, a valve body, a valve plate, a tower spring and the protective clothing, wherein a cavity is arranged in the adjusting cover, the bottom of the adjusting cover is open, and an exhaust port is arranged on the side surface of the adjusting cover; the middle part of the valve body is provided with a through hole, the top of the valve body is connected with the bottom of the adjusting cover, and the side surface of the lower end of the valve body is provided with an air inlet; the valve plate is arranged at the joint of the valve body and the adjusting cover and used for blocking the through hole of the valve body and the cavity of the adjusting cover; the tower spring is arranged in the cavity of the adjusting cover, one end of the tower spring abuts against the top of the adjusting cover, and the other end of the tower spring abuts against the valve plate; the protective clothing is connected with the middle part of the valve body.
In a preferred embodiment, the inner wall of the adjusting cover is provided with threads, and the outer wall of the valve body is provided with threads matched with the threads. The valve plate is connected with the valve body through a plastic buckle. And an adjusting screw is arranged on the side surface of the adjusting cover and penetrates through the adjusting cover to abut against the thread of the outer wall of the valve body. The tower spring is provided with a taper.
As shown in fig. 1: the protective clothing can block the entry of the venom and cannot cause any influence on the exhaust flow.
As shown in fig. 2: the exhaust flow is set according to the requirements of users, the compression amount of the tower spring is adjusted to a proper position by rotating the adjusting cover (with threads), and the exhalation resistance can be controlled by the locking screw. Because the tower spring is tapered, the tower spring can be better perpendicular to the sealing surface of the valve block and can move vertically along the axis direction all the time, and the structure enables the exhaust to be more stable and reliable.
To sum up: this discharge valve can effectively adjust expiration resistance and opening force, and the safety cover on the protective clothing can not influence the exhaust flow simultaneously, gives the comfortable exhaust flow of user, makes to wear this device and becomes a comfortable experience.
The working principle of the on-demand exhaust device applied to the protective clothing is as follows:
1. the plastic buckle presses the valve block on the valve body by using the elasticity of the tower spring, the valve block moves downwards by using the pressure of the entering gas, and the gas enters the valve cover from the opening area and is discharged.
2. The opening amount of the valve plate mainly depends on the supporting force of the tower spring, and the supporting force of the spring is realized by adjusting the compression amount of the spring through the rotary adjusting cover.
3. After gas enters the exhaust device, the valve plate is subjected to gas pressure to generate displacement, the opening can be enlarged according to the set displacement along with the increase of the pressure, the airflow is gradually enlarged along with the displacement, and finally the gas is discharged through the valve cover.
4. The regulating cover utilizes the screw thread of taking from to adjust the decrement of tower spring, and tower spring decrement is big more, and then the displacement resistance of valve block is big more, and gas flow just also is little, according to the principle, after the regulating cover rotates suitable position, can use the screw to lock current position, play fixed gas flow's effect.
