Abstract
The invention discloses an inclined-plane waterproof structure of a pressure switch. The inclined-plane waterproof structure comprises a sealing cover, a pressure switch, a sealing gasket, and a sealing ring. An opening is formed in the middle of the sealing cover, wherein the upper caliber of the opening is larger than the lower caliber of the opening; and an inclined plane is formed from the upper side of the opening to the lower side of the opening and a sealing ring slot is formed in the inclined plane. The pressure switch is arranged in the opening of the sealing cover; the sealing gasket is arranged between the pressure switch and the upper edge of the sealing cover; and the sealing ring is arranged between the pressure switch and the sealing ring slot of the inclined plane. The structure has the following beneficial effects: the interface opening size and the potential contact area are reduced; the sealing edge becomes regular, so that sealing becomes convenient and accurate; on the basis of the inclined plane structure, when water drop splashes into the structure, the water drop can flow outwardly along the inclined plane, thereby preventing water accumulation; and with the sealing ring for sealing, the waterproof performance is excellent.
Description
Technical field
The invention belongs to engineering machinery field, be specifically related to a kind of pressure switch inclined-plane waterproof construction.
Background technology
Pressure switch can be widely used in the fields such as oil, chemical industry, metallurgy, electric power, water supply the gauge pressure of various gas, liquid, the Survey control of absolute pressure, is the desirable intelligent measurement and control instrument of industry spot.It mainly adopts pressure sensor and the transmission circuit of high accuracy, high stable performance, then through dedicated cpu modular signal treatment technology, realizes the detection to pressure medium signal, display, warning and control signal and export.
Pressure switch has very important purposes in industrial circle, can prevent the damage of important device in production engineering, avoids the generation of great production accident.Therefore the security and stability of pressure switch is extremely important, and in order to realize this performance, water proofing property is its requisite requirement.
What existing pressure switch interface end generally adopted is plane contact, as shown in Figure 1, its by seal cover 1., pressure switch 2., 3. sealing gasket form, there is following shortcoming in this hermetically-sealed construction:
(1) water proofing property is low.Perforate is comparatively large, and engagement edge sealing laminating not, increase water inlet risk.
(2) ponding is not easy to discharge.Plane contact, if be accidentally splashed into water droplet, because flowing out without angle of inclination guiding, water droplet can accumulate and form ponding in contact-making surface place.Go down for a long time, ponding can corrode contact-making surface, flows in housing, then can damage internal component.
Summary of the invention
The object of this invention is to provide a kind of hermetically-sealed construction of engineering machinery wirking pressure switch, mainly through amendment pressure switch interface hermetically-sealed construction, the sealing of common plane contact is in the past revised as contact of incline plane sealing.
Technical scheme of the present invention is:
A kind of pressure switch inclined-plane waterproof construction, comprise seal cover, pressure switch, sealing gasket, sealing ring four part, seal cover middle opening, upper opening portion bore is greater than lower opening portion bore, upper opening portion becomes inclined-plane to lower opening portion, and described inclined-plane has seal groove, and pressure switch is placed in the opening of seal cover, sealing gasket is placed on pressure switch and seal cover between edge, and sealing ring is placed between the seal groove on pressure switch and described inclined-plane.
Innovative point of the present invention is modified by original plane sealing structure, utilizes the original inclined-plane of pressure switch interface, and it is inclined-plane that amendment is in contact with it face shape, and increases sealing ring to strengthen waterproof effect.
The present invention has following beneficial effect:
(1) reduce interface bore size, reduce potential contact area, regular seal edge then seals accurately convenient.
(2) ramp structure, when being splashed into water droplet, water droplet outwards can flow out along inclined-plane, and can not produce ponding.
(3) increase sealing ring sealing, water proofing property is higher.
Accompanying drawing explanation
Fig. 1 is existing pressure switch construction figure.
Fig. 2 is pressure switch inclined-plane waterproof construction figure of the present invention.
Embodiment
As shown in Figure 2, pressure switch inclined-plane of the present invention waterproof construction, comprise seal cover 1, pressure switch 2, sealing gasket 3, sealing ring 4 four part, seal cover middle opening, upper opening portion bore is greater than lower opening portion bore, and upper opening portion becomes inclined-plane to lower opening portion, described inclined-plane has seal groove 401, pressure switch is placed in the opening of seal cover, and sealing gasket is placed on pressure switch and seal cover between edge, and sealing ring is placed between the seal groove 401 on pressure switch and described inclined-plane.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.
