Abstract
The present invention relates to one kind from release diaphragm assembly, is made of flap, diaphragm, and pressure relief groove is preset on the diaphragm, and the pressure relief groove is located at the ball tapering position of diaphragm.In the present invention, valve seal band does not redesign pressure relief groove, and the body cavity ball conical surface can thus significantly reduce valve design, technology difficulty, improve economic benefit by being cast or machined into type；Especially machining sealing surface, the structure have evaded the difficult point of pressure relief groove processing, so that machining valve body applicability greatly improves.When valve opening, under valve rod active force, the ball conehead of diaphragm is lifted, and rubber of the cone top close to lumen position takes the lead in springing back, and exposes preset pressure relief groove.The medium that lumen accumulates into pressure relief groove, had not only eliminated the suction-operated of diaphragm and valve body, but also reduce the pressure difference between lumen and diaphragm, and had greatly reduced the opening force of valve under pipeline pressure effect.
Description
Technical field
The present invention relates to a kind of diaphragm assembly, more particularly, to one kind from release diaphragm assembly.
Background technique
M type straight way diaphragm valve run when, under pressure, dielectric breakdown input end diaphragm pre-tighten, into diaphragm with
The cavity that valve deck is formed forms partial high pressure；Meanwhile diaphragm and valve seal pair form adsorption effect, to greatly increase valve
Door opening force, or even cause diaphragm failures.Therefore, heavy caliber valve body designs on non-processing band pressure relief groove, but this is close
Sealing groove is not easy to realize on the band of machine-shaping.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind from release diaphragm group
Part.The present invention is to increase valve body pressure relief capability under the premise of not changing overall structure, protects valve body and diaphragm.
The purpose of the present invention can be achieved through the following technical solutions:
One kind is made of from release diaphragm assembly flap, diaphragm, and pressure relief groove, the pressure relief groove are preset on the diaphragm
Positioned at the ball tapering of diaphragm position.Pressure relief groove can guarantee gradually release when valve opening, protection diaphragm safety.
The diaphragm is made using compression molding.
The flap is bonded with the inside of diaphragm.
The bottom of the flap is ball wimble structure, and the bottom of the diaphragm is ball wimble structure.
The material of the diaphragm is rubber.
The upper end of the diaphragm is closely connect with valve body.
The valve body is equipped with band, not set pressure relief groove on the band.
The flap top and the valve rod nested encryptions.
The pressure relief groove gradually release in valve opening.
In the present invention, valve seal band does not redesign pressure relief groove, and the body cavity ball conical surface can be by being cast or machined into
Type thus significantly reduces valve design, technology difficulty, improves economic benefit；Especially machining sealing
Face, the structure have evaded the difficult point of pressure relief groove processing, so that machining valve body applicability greatly improves.
When valve opening, under valve rod active force, the ball conehead of diaphragm is lifted, rubber of the cone top close to lumen position
It takes the lead in springing back, exposes preset pressure relief groove.The medium that lumen accumulates, into pressure relief groove, both eliminated under pipeline pressure effect
The suction-operated of diaphragm and valve body, and the pressure difference between lumen and diaphragm is reduced, greatly reduce the opening force of valve.
Compared with prior art, the invention has the following advantages:
1. position is arranged by changing pressure relief groove, not only obtains anticipation function under the premise of not changing overall structure
It realizes very well, and effectively increases the molding convenience of parts machining and economy.
2. evading the design of machining pressure relief groove, critical technological point, the applicability of machining valve body is improved.Machining sealing
The valve body in face, it is easier to guarantee the precision and quality of sealing surface, more conducively guarantee diaphragm and valve body from centring property, also more hold
The decrement of diaphragm easy to control improves diaphragm working environment, to extend diaphragm service life.
3. diaphragm is adjusted pressure relief groove placed on it as vulnerable part, craftsmanship, economy are better than to valve
Body carries out structure improvement.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the present invention from release diaphragm assembly；
Fig. 2 is enlarged structure schematic diagram at A in Fig. 1.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
With reference to Fig. 1, Fig. 2, one kind is made of flap 1, diaphragm 2 from release diaphragm assembly, is preset with pressure relief groove on diaphragm 2
3, pressure relief groove 3 is located at the ball tapering position of diaphragm.The gradually release in valve opening of pressure relief groove 3.Pressure relief groove 3 can guarantee that valve is opened
Gradually release when opening, protection diaphragm safety.
Diaphragm 2 is made using compression molding.Flap 1 is bonded with the inside of diaphragm 2.The bottom of flap 1 is ball wimble structure, every
The bottom of film 2 is ball wimble structure.The material of diaphragm 2 is rubber.The upper end of diaphragm 2 is closely connect with valve body 4.Valve body 4 is equipped with
Band, not set pressure relief groove on band.1 top of flap and valve rod nested encryptions.
In the present embodiment, valve seal band does not redesign pressure relief groove, and the body cavity ball conical surface can be by casting or machining
Molding, thus significantly reduces valve design, technology difficulty, improves economic benefit；Especially machining is close
Cover, the structure have evaded the difficult point of pressure relief groove processing, so that machining valve body applicability greatly improves.
When valve opening, under valve rod active force, the ball conehead of diaphragm is lifted, rubber of the cone top close to lumen position
It takes the lead in springing back, exposes preset pressure relief groove.The medium that lumen accumulates, into pressure relief groove, both eliminated under pipeline pressure effect
The suction-operated of diaphragm and valve body, and the pressure difference between lumen and diaphragm is reduced, greatly reduce the opening force of valve.
