Straight-through type breather valve and suction dryer thereof

Technical Field

The utility model relates to the technical field of valves, especially be used for the suction machine, specifically be a through type breather valve and suction machine thereof.

Background

The absorption dryer is named as an adsorption dryer, and the principle of the absorption dryer is that saturated compressed air is filtered by a special molecular sieve for gas purification by utilizing the difference of moisture and air molecular volume, water molecules can be easily absorbed in molecular sieve particles, the molecular sieve is reduced by a regeneration method, and the dew point of the compressed air can easily reach-40 ℃.

The adsorption dryer achieves the drying effect by pressure change (pressure swing adsorption principle). Since the capacity of air to contain water vapor is inversely proportional to the pressure, a part of the air (called regeneration air) after drying is decompressed and expanded to the atmospheric pressure, the expanded air becomes drier due to the pressure change, then the expanded air flows through a drying agent layer (namely a drying tower which absorbs enough water vapor) to be regenerated, which is not communicated with the air flow, and the dried regeneration air sucks out of the moisture in the drying agent and carries the drying agent out of the dryer to achieve the purpose of dehumidification. The two towers work circularly, do not need a heat source, and continuously provide dry compressed air for a user air system.

The sucking and drying machine comprises a vent valve for controlling the on-off of the air path. The traditional vent valve is inconvenient to operate because the on-off is controlled by the expansion or rotation of the valve rod, and the valve rod is easy to wear, so that the service life is short; moreover, the replacement of the valve rod can involve the disassembly and assembly of the valve, and the operation is more complicated. The vent valve also has a drawback: the gas path typically turns, resulting in a relatively high gas path resistance.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 3, the utility model discloses a through type breather valve, including valve body 1, case 2 and solenoid valve 4, solenoid valve 4 is two-position three way solenoid valve. The valve body 1 is internally provided with a gas path 3, and the gas path 3 is of a straight-through type and penetrates through two opposite ends of the valve body 1.

The valve core 2 is arranged in the inner cavity of the valve body 1 and is provided with a connecting air hole 14 communicated with the air passage 3. The connecting air hole 14 is perpendicular to the air path 3 and is connected with the interface of the electromagnetic valve 4, so that the electromagnetic valve 4 drives the valve core 2 to control the on-off of the air path 3.

The electromagnetic valve 4 replaces a traditional valve rod, so that the phenomenon of abrasion is avoided, the service life is longer, the electromagnetic valve 4 is not required to be replaced, the valve is not required to be disassembled and assembled, and the operation is simple and convenient; the straight-through design of the gas path 3 reduces the resistance of the gas path 3.

Example two:

compared with the first embodiment, the differences are as follows: as shown in fig. 2, the valve body 1 comprises a valve head 11 and a valve tail 12 which are connected by four evenly distributed bolts. The air passage 3 penetrates through the valve head 11 and the valve tail 12, and an inlet 31 of the air passage is arranged on the valve head 11, and an outlet 32 of the air passage is arranged on the valve tail 12. One end of the valve tail 12 connected with the valve head 11 is provided with a concave platform 13 for installing the valve core 2, so that the valve core 2 can be conveniently installed.

Example three:

compared with the two examples, the difference is that: as shown in fig. 4, the inlet 31 is a blind hole. Because the diameter of entry 31 is fixed, under the different work condition circumstances, the gas flow that needs is also different, so need be equipped with the valve head 11 of multiple different entry 31 diameters to lead to the cost higher, consequently above-mentioned setting, according to the work condition circumstances, directly with the blind hole break through into the demand the through-hole can, not only the cost is reduced, the operation is also simple and convenient moreover.

Example four:

compared with the three phases of the embodiment, the differences are as follows: as shown in fig. 4, the bottom of the inlet 31 is tapered. Because the position that the blind hole was punched is difficult to inject, the phenomenon that the through-hole and the 3 decentractions of gas circuit of punching can appear to lead to the air pressure inequality in the gas circuit 3, consequently the toper design of entry 31 bottom leads to and is spacing to the position of punching of drill bit, ensures that the drill bit is put at the central point of entry 31 bottoms and drills.

Example five:

compared with the two examples, the difference is that: as shown in fig. 5, the valve tail 12 is further provided with an exhaust hole 15 connected to another port of the solenoid valve 4. The exhaust hole 15 includes two portions perpendicular to each other, one portion being parallel to the air hole, and the other portion being parallel to the connection air hole 14. When the vent valve works, the electromagnetic valve 4 controls the exhaust hole 15 to enable the exhaust hole 15 to be in a normally closed state; when the breather valve is out of work, the electromagnetic valve 4 controls the exhaust hole 15 to be opened, and high-pressure gas in the valve body 1 is exhausted, so that when the breather valve is out of work, the pressure of the high-pressure gas in the valve body 1 cannot be applied, and the breather valve is damaged.
