Description
Technical Field
The utility model relates to a solenoid valve sealing washer structure especially relates to a prevent that solenoid valve from producing the sealing member of outer leakage under the ultra-low temperature medium effect, belongs to solenoid valve application technical field.
Background
In the field of application of solenoid valves, as shown in fig. 1, rubber seals a are often used for sealing between various portions of the solenoid valves. Since the rubber seal a is hardened at a low temperature, the ductility of the sealing material is lost, and the sealing performance is lost, which causes problems such as external leakage and internal leakage of the solenoid valve. Particularly in ultra-low temperature (lowest temperature-196 ℃ liquid nitrogen application condition) application, the rubber sealing element can be hardened and cracked due to low temperature, so that the solenoid valve fails. Besides the failure of the solenoid valve itself due to leakage of the solenoid valve, the leakage of the cryogenic medium can cause damage to the equipment and instruments.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: how to avoid the problem that the electromagnetic valve leaks under the ultralow temperature medium application environment.
In order to solve the technical problem, the technical scheme of the utility model is to provide a sealing ring structure of a solenoid valve, which comprises a connecting gland and a valve body, and is characterized in that the connecting gland and the valve body are hermetically connected through a red copper sealing ring; a groove is arranged on a contact surface between the connecting gland and the valve body on the connecting gland or the valve body, and the red copper sealing ring is arranged in the groove; when the connecting gland is not connected with the valve body and screwed down, the red copper sealing ring is not deformed, and a gap is reserved between the connecting gland and the valve body; after the connecting gland is connected with the valve body and screwed down, the red copper sealing ring deforms, the side face of the red copper sealing ring is connected with the side face of the groove in a sealing mode, the bottom of the red copper sealing ring is connected with the bottom of the groove in a sealing mode, and the top of the red copper sealing ring is connected with the connecting gland in a sealing mode.
Preferably, the cross section of the red copper sealing ring is prismatic.
Preferably, the connection gland divide into two parts about, upper portion cross section is greater than the cross section of lower part, the lower part of connecting the gland is located in the valve body and through screw thread fastening connection, the upper portion of connecting the gland is close to between one side of valve body and the valve body through red copper sealing ring sealing connection.
The utility model discloses a red copper sealing ring's use for the solenoid valve has avoided the cracked condition of rubber seal ring sclerosis low temperature under the environment of ultra-low temperature, because red copper's rigidity is stronger than soft sealed rubber seal spare, so can more effectually bear the impact of the inside medium pressure of valve body to the sealing ring, prevent that the solenoid valve from producing outside leakage between connecting gland and valve body.
Will the utility model discloses a product structure and prior art's product structure carry out contrast experiment under the same test condition, can obtain the utility model discloses a product structure can effectively prevent that the low temperature medium from leaking.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model provides a solenoid valve sealing washer structure, as shown in figure 2, it is including connecting gland 1 and valve body 3, connect gland 1 and divide into two parts from top to bottom, the upper portion cross section is greater than the cross section of lower part, the lower part of connecting gland 1 is located in valve body 3 and is connected through screw fastening, connect gland 1's upper portion be close to between one side of valve body 3 and the valve body 3 through red copper sealing ring 2 sealing connection, the upper surface of valve body 3 is equipped with the recess, the recess is located the contact surface of connecting between gland 1 and the valve body 3, red copper sealing ring 2 is located in the recess.
Wherein, the section of the red copper sealing ring 2 is prismatic, as shown in fig. 5-7. The red copper sealing ring 2 is compressed and then is filled with a stuffing box, namely, a cavity formed by the grooves for connecting the gland 1 and the valve body 3 is filled, and the red copper is easy to plastically deform and has certain metal rigidity, so that the whole cavity can be filled with the red copper sealing ring comfortably and the red copper sealing ring can resist the pressure impact of a medium (the rubber sealing member is deformed under the action of pressure to realize sealing).
The appearance characteristic of sealing ring is also very important, in this embodiment, the top at the both ends of red copper sealing ring 2 is a small-size isosceles trapezoid cross-sectional structure, this kind of structure can be very effectual play red copper sealing ring 2 and connect gland 1, the small area contact of the recess bottom surface of red copper sealing ring 2 and valve body 3 (realize line seal promptly, can improve the sealed effect between metal and the metal), simultaneously when connecting gland 1 and receiving the moment of torsion effect, when compressing tightly red copper sealing ring 2, the red copper sealing ring 2 distortion that produces because of deformation can be absorbed to this structure.
As shown in fig. 2, when the connecting gland 1 is not connected with the valve body 3 and screwed tightly, the red copper sealing ring 2 is not deformed, and a gap a is left between the connecting gland 1 and the valve body 3;
as shown in fig. 3, after the connecting gland 1 is connected with the valve body 3 and screwed, the red copper sealing ring 2 deforms, fills the stuffing box formed between the valve body 3 and the connecting gland 1, and forms reliable surface sealing on four surfaces (namely, the left surface and the right surface of the red copper sealing ring 2 are in sealing connection with two side surfaces of the groove, and the upper surface and the lower surface are in sealing connection with the connecting gland 1 and the bottom of the groove respectively), and meanwhile, the external leakage of a product is effectively prevented by adding the ductility of the red copper.
The red copper sealing ring and the red copper gasket are made of the same material and are only different in shape. The corrugated metal clad gasket is made of expanded graphite, asbestos-free plate, polytetrafluoroethylene, ceramic fiber and other fillers, and is externally clad with metal sheets of various materials such as stainless steel, tinplate, red copper and the like by a specific cold working process, is particularly suitable for high-temperature and high-pressure sealing parts such as heat exchangers, pressure vessels and the like, can effectively prevent the scattering of the gasket and the corrosion of media, and simultaneously improves the pressure resistance Reactor, etc.) sealing of the flange).
