Description

Decompression valve for microbial deodorant packaging barrel

Technical Field

The utility model belongs to the field of machinery, especially, relate to a relief valve for microbial deodorant pail pack.

Background

The microbial deodorant is a solution containing microorganisms, and is used for being sprayed on odor emitting articles such as garbage and the like to degrade odor therein through the microorganisms. But microorganism deodorant is usually preserved in inclosed bucket, and microorganism can produce gas because of reasons such as metabolism in the preservation process, lead to the bucket internal pressure to rise, consequently can install the relief valve on deodorant's the pail pack usually and carry out the pressure release, the relief valve structure commonly used is as shown in figure 1, including valve body 1, the valve body is internal to be formed with cavity 2, cavity 2 bottom is formed with the first siphunculus 3 with the pail pack intercommunication, cavity 2 top is connected with clamp plate 5 through spring 4, clamp plate 5 lid is on first siphunculus 3, the upper portion side is formed with the second siphunculus 6 with outside intercommunication in the cavity 2. Since the pressure relief valve starts to relieve pressure only when a certain pressure is ensured, the pressure plate 5 and the cavity 2 are usually in an interference fit state. In addition, in the transportation process of the microbial deodorant, the pressing plate 5 may be jacked up by the microbial deodorant due to the influence of bumping and the like, and in order to prevent the microbial deodorant from escaping to the upper side of the pressing plate 5 from a gap between the pressing plate 5 and the side wall of the cavity 2, and then after pressure relief is finished, the escaped bacteria liquid cannot flow back, so that the cavity above the pressing plate 5 is easily polluted by the bacteria liquid or blocked by mildew, and therefore the pressing plate 5 and the cavity 2 also need to be in an interference fit state. But the problem that interference fit leads to lies in, and 5 pressure release at every turn upwards when by jack-up, must be through the entry of second siphunculus 6, and pressure release at every turn like this, 5 all have the position to crowd the entry of second siphunculus 6 of clamp plate to with the entrance friction, lead to 5 avris of clamp plate to abrade very easily and appear the gap, thereby arouse that cavity 2 of relief valve blocks up.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the following embodiments and accompanying drawings.

Example 1

The pressure release valve for the microbial deodorant packaging barrel shown in fig. 2 comprises a valve body 1, wherein an upper cavity 7 and a lower cavity 8 are formed in the valve body 1; the lower cavity 8 is communicated with the packaging barrel through a third pipeline 9, the top of the upper cavity 7 and the bottom of the lower cavity 8 are communicated with each other through a fourth pipeline 10, and a fifth pipeline 11 communicated with the outside is formed on the side wall of the fourth pipeline 10; the top of the upper cavity 7 is connected with a first pressing plate 14 covering the top of the fourth pipeline 10 through a first elastic piece 13; the top of the lower cavity 8 is connected with a second pressing plate 16 covering the third pipeline 9 through a second elastic piece 15; a push rod 17 matched with the first pressure plate 14 is fixed at the top of the second pressure plate 16; the side wall of the third pipeline 9 is communicated with the side wall of the upper cavity 7 through a sixth pipeline 18; the radial area of the third duct 9 is greater than the area of the first platen 14; the second pressing plate 16 is in interference fit with the side wall of the lower cavity 8; a plug 12 for plugging the lower end of the fourth pipeline 10 is formed at the top of the lower cavity 8, and the plug 12 is connected with a push rod 17 in a sliding manner.

The utility model discloses the theory of use as follows: when the pressure in the packaging barrel rises and needs to be relieved, the second pressing plate 16 is jacked up, meanwhile, the push rod 17 is driven to move upwards, and as the radial area of the third pipeline 9 is larger than that of the first pressing plate 14, the jacking force jacked up by the second pressing plate 16 is inevitably larger than the pressure of the first pressing plate 14, so that the first pressing plate 14 is jacked up, and then the gas overflows through the third pipeline 9, the sixth pipeline 18, the fourth pipeline 10 and the fifth pipeline 11 in sequence, thereby achieving the purpose of relieving the pressure. In the early movement, the side surfaces of the first pressure plate 14 and the second pressure plate do not rub against the recessed pipe port, so that the side surfaces can be prevented from being damaged, and the service life of the piston is prolonged.

The first elastic member 13 and the second elastic member 15 are both springs. The first and second platens 14, 16 are each made of rubber. The valve body 1 is installed on a cover or a barrel body of the packaging barrel.

A spherical baffle plate 19 is formed at the lower end of the third pipeline 9 in a downward protruding mode, and air holes 20 are formed in the baffle plate 19, so that the spherical baffle plate 19 forms a cavity which gradually increases from bottom to top, and therefore bacterial liquid is prevented from being rapidly flushed out along with air when pressure is relieved.

The outlet of the fifth pipeline 11 is at the side or top surface of the valve body 1.

The above-mentioned is only a concrete direction embodiment of the utility model, nevertheless the utility model discloses a design concept is not limited to this, and all utilize this design right the utility model discloses carry out immaterial change, all should belong to the action of infringing the scope of protection of the utility model.
