Description

Vent

This creation is about an exhaust valve.

Press, after the general food is bagged, in order to make the air in the bag exhaust effectively and prevent the outside air from entering, an exhaust valve with one-way exhaust function will be installed. In the air hole of a valve seat, in order to effectively achieve the tightness, a working fluid with high viscosity (such as silicon oil) will be coated between the periphery of the air hole and the valve plate, so that the gas in the bag can pass through the valve plate After being discharged, the valve sheet can continue to be closely attached to the periphery of the vent hole. However, when the valve plate is closely attached to the periphery of the vent hole, the working fluid will be squeezed and overflow to the outer periphery of the valve plate, so that the one-way exhaust function will be lost due to the loss of the working fluid. The exhaust valves are mass-produced and then assembled with the bags separately, which will cause the working fluid to overflow and contaminate other exhaust valves, and there are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive exhaust valve to solve the above problems.

The main purpose of this invention is to provide an exhaust valve, which can effectively prevent the working fluid of the exhaust valve from overflowing to pollute other exhaust valves or foreign objects, and also prevent the exhaust valve from losing its one-way exhaust function.

To achieve the above purpose, the invention provides an exhaust valve, which includes a base and a valve plate. The seat body includes a base plate, the base plate is provided with at least one exhaust hole, the base plate includes a first side opposite to a second side, the first side is provided with an annular groove surrounding the at least one exhaust hole, The ring groove is used to accommodate working fluid with a viscosity greater than water. The valve plate cover is arranged on the first side and the ring groove.

The following examples are only used to illustrate the possible implementation of this creation, but it is not intended to limit the scope of protection of this creation, and it will be described first.

Please refer to FIGS. 1 to 5 , which show a preferred embodiment of the invention. The exhaust valve of the invention includes a seat body 1 and a valve plate 2 .

The seat body 1 includes a bottom plate 11, the bottom plate 11 is provided with at least one exhaust hole 121, the bottom plate 11 includes a first side 13 and a second side 14 opposite to each other, the first side 13 is provided around the at least one An annular groove 15 of a vent hole 121, the annular groove 15 is used to hold a working fluid with a viscosity greater than water, in this embodiment the working fluid is silicon oil, in this embodiment the base 1 is installed in a bag Body 9.

The valve plate 2 covers the first side 13 and the ring groove 15 .

Thereby, since the working fluid system is accommodated in the annular groove 15, the annular groove 15 can have the function of guiding the flow of the working fluid, so that the working fluid can evenly connect with the valve plate 2, so the valve plate 2 can be more tightly attached to the first side 13, and the ring groove 15 can be used to accommodate the working fluid to prevent the working fluid from overflowing to the outer periphery of the valve plate 2, so the invention can more effectively preserve the working fluid In order to avoid the reduction of the one-way exhaust function of the valve plate 2 after the loss of the working fluid, and to prevent the working fluid from overflowing and polluting other exhaust valves and foreign objects.

Specifically, the seat body 1 includes a first ring wall 16 connected to the bottom plate 11, a plurality of stoppers 161 protrude from the inner peripheral wall at one end of the first ring wall 16, and the valve plate 2 is located in the first ring wall 16 and limited between the bottom plate 11 and the stoppers 161, so as to prevent the valve plate 2 from accidentally falling out of the first ring wall 16.

Wherein, the end of the first ring wall 16 away from the stoppers 161 is radially outwardly provided with a first flange 162, and the outer periphery of the first flange 162 is provided with a second ring wall 17, the second ring The wall 17 can protect the first ring wall 16 and prevent the first ring wall 16 from external impact. Preferably, an end of the second ring wall 17 away from the first flange 162 protrudes axially from the first ring wall 16 to further protect the first ring wall 16 .

In this embodiment, the end of the second ring wall 17 away from the first flange 162 protrudes radially outwards with a second flange 171 for connecting to the bag body 9 The bottom plate 11 corresponds to a hole (not shown) provided in the bag body 9, so that the gas in the bag body 9 can be exhausted effectively.

Also preferably, the bottom plate 11 is adjacent to one end of the first ring wall 16 and a groove 18 is formed between the second side 14 and the first ring wall 16 to protect the bottom plate 11 from being damaged by the bottom plate 11. The outside world collides.

In this embodiment, the bottom plate 11 is provided with a perforation 12, and the inner peripheral wall of the perforation 12 is provided with a plurality of ribs 122. The structural strength of the first ring wall 16 can be effectively enhanced.

In addition, the groove depth of the annular groove 15 is smaller than the thickness of the valve plate 2 in the axial direction, which can prevent the annular groove 15 from accommodating too much working fluid and causing waste. The radial dimension of the valve plate 2 is larger than the radial dimension of the annular groove 15 Dimensions to effectively prevent the working fluid from overflowing to the outer periphery of the valve plate 2.
