Abstract
The utility model discloses a sealing structure of a one-way valve. The one-way valve is provided with an installation hole (1); the circumference of the installation hole (1) is provided with an exhaust hole (2); the installation hole (1) is internally provided with an umbrella-shaped membrane (3); and the umbrella opening (4) of the umbrella-shaped membrane (3) covers the exhaust hole (2). In the utility model, the planar membrane is replaced by the umbrella-shaped membrane, the sealing structure of the gas one-way valve breaks through the existing structure form, and the system valve to which the sealing structure is applied obtains breakthrough development on the requirements of reliability, air-tightness and vacuum degree, thus leading the product to have simpler structure, higher reliability and achieve the effects of miniaturization and lightness; and simultaneously, the air-tightness and the flow of the product are greatly improved. As the umbrella-shaped membrane is made of rubber or soft plastic which has excellent plastic deformation characteristic, the installation can be completed only by plugging the boss of the umbrella-shaped membrane into the installation hole of the one-way valve and fixing the boss with the installation hole by a silicone rubber adhesive, therefore, the installation is extremely convenient.
Description
Technical field
The utility model relates to the sealing configuration of a kind of sealing configuration, particularly a kind of one-way valve.
Background technique
In the present one-way valve sealing configuration, the basic structure of the one-way valve diaphragm that seals is plane normally, the one-way valve diaphragm is to lean on the pressing plate and the screw on two sides to be installed on the one-way valve, the one-way valve diaphragm of this plane is installed cumbersome, and reliability and poor air-tightness, use on vacuum pump, not reach the degree of vacuum of requirement.
The model utility content
The purpose of this utility model is, a kind of sealing configuration of new one-way valve is provided, and it is easy for installation, and can improve reliability and tightness, can satisfy the degree of vacuum requirement of vacuum pump.
The technical solution of the utility model: a kind of sealing configuration of one-way valve, one-way valve is provided with mounting hole, is provided with exhaust port around the mounting hole; Be provided with the umbrella shape diaphragm in the mounting hole, the umbrella mouth of umbrella shape diaphragm covers exhaust port.
In the sealing configuration of above-mentioned one-way valve, described umbrella shape diaphragm is that rubber or soft plastic are made.
In the sealing configuration of aforesaid one-way valve, described umbrella shape diaphragm comprises pillar, and the pillar two ends are provided with boss, and one of them boss is provided with umbrella crown.
In the sealing configuration of aforesaid one-way valve, described umbrella crown diameter is greater than the exhaust port external profile diameter.
In the sealing configuration of aforesaid one-way valve, described umbrella crown thickness is from outside to inside thickeied gradually.
Compared with prior art, the utility model adopts the umbrella shape diaphragm to substitute the plane diaphragm, sealing configuration on the gas unidirectional valve has been broken through structural type in the past, use system of the present utility model valve body and obtaining breakthrough aspect reliability and tightness and the degree of vacuum requirement, make product structure simpler, reliability is higher, and product has reached miniaturization and light-weighted effect, and the tightness and the flow of product are greatly improved simultaneously.Because the umbellate form diaphragm is made with rubber or soft plastic, have good plastic deformation when mounted, thus when installing as long as the boss on the umbellate form diaphragm is filled in the mounting hole of one-way valve, and get final product with silicon rubber bonder is fixing.So install very convenient.
Description of drawings
Fig. 1 is a knot schematic representation of the present utility model;
Fig. 2 is the structural representation of umbrella shape diaphragm.
Being labeled as in the accompanying drawing: 1-mounting hole, 2-exhaust port, 3-umbrella shape diaphragm, 4-umbrella mouth, 5-pillar, 6-boss, 7-umbrella crown.
Embodiment
Be described in further detail below in conjunction with the sealing configuration of drawings and Examples a kind of one-way valve of the present utility model, but not as the foundation of the utility model being done any restriction.
Embodiment.The structured flowchart of the sealing configuration of one-way valve of the present utility model as shown in Figure 1.One-way valve is provided with mounting hole 1, is provided with exhaust port 2 around the mounting hole 1; It is characterized in that: the umbrella shape diaphragm made from rubber or soft plastic 3 is installed in the mounting hole 1, and umbrella mouth 4 diameters of umbrella shape diaphragm 3 are greater than exhaust port 2 external profile diameters.Umbrella mouth 4 covers the exhaust port around the mounting hole 12.Described umbrella shape diaphragm 3 as shown in Figure 2, it comprises pillar 5, pillar 5 two ends are provided with boss 6, one of them boss 6 is provided with umbrella crown 7.Umbrella crown 7 thickness is from outside to inside thickeied gradually.
Working principle of the present utility model
The utility model is the draught head work that relies on umbrella shape diaphragm 3 both sides at work, and when umbrella shape diaphragm 3 umbrellas pushed up a surface pressure greater than umbrella mouth one end pressure, shown in the right of Fig. 1, arrow was the flow direction of gas among the figure.The umbrella crown pressurized of umbrella shape diaphragm 3 shrinks the umbrella mouth distortion of umbellate form diaphragm, umbrella mouth edge and valve body end face are fitted, the area of contact of umbrella mouth and one-way valve increases, (exhaust port is 4～6 to umbrella mouth 4 with the exhaust port 2 around the mounting hole 1, circumference uniform distribution, between maximum cylindrical of umbrella shape diaphragm and pillar, see Fig. 1 for details) the tight covering, can improve reliability and tightness.
On the contrary, when umbrella shape diaphragm 3 umbrella mouths one surface pressure pushed up an end pressure greater than umbrella, shown in the left side of Fig. 1, arrow was the flow direction of gas among the figure.The umbrella crown of umbrella shape diaphragm 3 is subjected to the pressure of umbrella mouth direction, pressure is opened the umbrella mouth distortion of umbrella shape diaphragm 3, umbrella mouth edge separates with the valve body end face, between valve body end face and umbrella shape diaphragm 3, produce the gap, make gas discharge the effect of playing one-way valve by the gap between exhaust port 2 and valve body end face and the umbrella shape diaphragm 3.
The application of the sealing configuration of one-way valve of the present utility model can make one-way valve structures simple, compact, has improved reliability of products and tightness, and the degree of vacuum of vacuum pump reaches below the 30Kpa.The utility model uses and obtained breakthrough on the valve body of system, makes product structure simple, and reliability height, product have reached miniaturization and light-weighted effect, and the tightness and the flow of product are greatly improved simultaneously, and degree of vacuum can reach below the 30Kpa.
