Abstract
The utility model discloses a pressure switch inclined plane waterproof construction, including sealed lid, pressure switch, sealed pad, sealing washer four bibliographic categories branch, opening in the middle of the sealed lid, opening upper portion bore are greater than opening lower part bore, opening upper portion to opening lower part one -tenth inclined plane, it has the seal groove to open on the inclined plane, and in pressure switch arranged the opening of sealed lid in, sealed pad was arranged pressure switch in and is covered between along with sealed, the sealing washer arrange in pressure switch and between the seal groove on the inclined plane. The utility model discloses following beneficial effect has: having reduced interface cut out dimension, having reduced potential area of contact, regular sealing margin is then sealed convenient more accurate, the inclined plane structure, when spattering into the water droplet, the water droplet can be followed the inclined plane and outwards flowed out, and can not produce ponding, it is sealed to increase the sealing washer, and waterproof nature is higher.
Description
Technical field
The utility model belongs to engineering machinery field, is 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.
Utility model content
The purpose of this utility model 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.
The technical solution of the utility model 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 utility model 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 utility model 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 the utility model pressure switch inclined-plane waterproof construction figure.
Embodiment
As shown in Figure 2, pressure switch inclined-plane of the present utility model 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 utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
Claims (1)
