Description

Technical Field

[0001] The utility model relates to the technical field of air release valves, in particular to an adjustable manual air release valve. Background Art

[0002] The bleed valve is also called the exhaust valve. When gas escapes from the system, the gas will climb up along the pipe and eventually gather at the highest point of the system. The exhaust valve is generally installed at the highest point of the system. When the gas enters the exhaust valve cavity, it gathers at the upper part of the exhaust valve. However, in actual use, similar bleed valves still have many defects. For example, the existing bleed valve cannot control the speed of gas release, and it is impossible to visually analyze whether the gas has been completely discharged. There are great safety hazards if subsequent work is carried out rashly. Utility Model Content

[0003] The purpose of the utility model is to provide an adjustable manual air release valve to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an adjustable manual air release valve, comprising a valve body, an inner cavity being opened inside the valve body, a threaded hole being opened at the center of the upper end of the valve body, a telescopic rod being engaged and installed inside the threaded hole, an external thread being provided on the upper part of the outer wall of the telescopic rod, and the threaded hole being matched with the external thread.

[0005] When using the adjustable manual air release valve, when the air release operation is required, the handle is manually turned, and the handle drives the telescopic rod to rotate. The external thread on the outer wall of the telescopic rod cooperates with the threaded hole, so that the telescopic rod slowly extends outward. At this time, the gas can be discharged through the lowest air outlet. Continue to turn the handle. The distance risen after each two turns is the same as the spacing between the air outlet holes. The number of air outlet holes used can be determined by turning different numbers of circles, thereby adjusting the air outlet volume. An air plate is provided on the outer wall of the valve body. When the gas is discharged from the air outlet, the air plate will be blown to make the rotating shaft rotate around the shaft hole. The gas can be observed with the naked eye to see whether all the gas is discharged. The air plate can break up the strong airflow and prevent the gas from blowing directly to the hand that twists the handle after discharge.

[0006] As an optimal technical solution of the present invention, a boss is provided at the lower end of the inner cavity, a sealing ring is fixedly installed in the middle of the boss, and an air vent is opened at the center of the lower end of the boss, and the air vent is communicated with the inner cavity; by providing the sealing ring, the sealing of the valve body can be ensured when there is no need to deflate.

[0007] As a preferred technical solution of the present invention, a sealing block is fixedly installed at the lower end of the telescopic rod, the outer surface of the sealing block is in contact with the inner surface of the boss, and a spring is fixedly installed at the upper end of the sealing block, and the other end of the spring is connected to the top of the inner cavity; by providing a spring, it can prevent the gas from pushing out the telescopic rod when no one turns the handle.

[0008] As a preferred technical solution of the present invention, a sealing nail is fixedly installed at the center of the lower end of the sealing block, and the sealing nail cooperates with the air vent.

[0009] As a preferred technical solution of the present invention, a plurality of groups of air outlet holes are opened on one side of the outer wall of the valve body, and fixing plates are fixedly installed on both ends of the air outlet holes on the outer wall of the valve body.

[0010] As an optimal technical solution of the present invention, an axial hole is opened at the center of the two groups of fixed plates, a rotating shaft is rotatably installed inside the axial hole, and several groups of wind plates are evenly installed on the outer wall of the rotating shaft; by providing the wind plates, the gas first contacts the wind plates after being discharged, and the wind plates can disperse the discharged gas in the first time.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. When using an adjustable manual air release valve, when deflation is required, manually turn the handle, the handle drives the telescopic rod to rotate, the external thread on the outer wall of the telescopic rod cooperates with the threaded hole, so that the telescopic rod slowly extends outward, and the gas can be discharged through the lowest air outlet. Continue to turn the handle. The distance increased after each two turns is the same as the spacing between the air outlet holes. The number of air outlet holes used can be determined by turning different numbers of circles, thereby adjusting the air outlet volume. An air plate is provided on the outer wall of the valve body. When the gas is discharged from the air outlet, the air plate will be blown to make the shaft rotate around the shaft hole. The gas can be observed with the naked eye to see whether all the gas is discharged. The air plate can break up the strong airflow and prevent the gas from blowing directly to the hand that twists the handle after discharge.

[0013] 2. By setting up a wind plate, when the gas is discharged from the air outlet, it will blow the wind plate, causing the shaft to rotate around the shaft hole. You can observe with the naked eye whether the gas is completely discharged. The wind plate can disperse strong airflows and prevent the gas from blowing directly onto the hand that twists the handle after being discharged. BRIEF DESCRIPTION OF THE DRAWINGS
