Abstract
The utility model relates to a switch, in particular to pressure switch. The utility model provides a following technical scheme: a pressure switch, the rocker switch structure comprises a housing, be equipped with inhalant canal on the shell, the chamber of inhalant canal and exhalant canal is connected to exhalant canal and being used for, be equipped with micro -gap switch in the shell, micro -gap switch is equipped with the drive micro -gap switch diaphragm of opening or closing with being connected between the chamber, inhalant canal and the parallel parallel configuration of exhalant canal are on the shell, inhalant canal is including end and the water delivery end of intaking, the exhalant canal is including the link and go out the water end (W. E. ), inhalant canal's water delivery end switches on through the link of connecting chamber and exhalant canal, the end department of intaking that the shell lies in inhalant canal is equipped with the installation step, it is equipped with the sealing washer to overlap respectively on the installation step. Adopt above -mentioned technical scheme, provide one kind and prevented medium refluence, simple structure, installation and process convenient pressure switch.
Description
Technical field
This utility model relates to a kind of switch, particularly to a kind of pressure switch.
Background technology
Traditional pressure switch includes shell, and shell is provided with intake tunnel, exhalant canal and for connecting the connection chamber of intake tunnel and exhalant canal, is provided with and the microswitch of diaphragm linkage in shell. When medium is entered by intake tunnel, diaphragm is implemented to compress by medium, and diaphragm touches microswitch after being subject to certain pressure, and microswitch is turned on and off.
But, the intake tunnel of traditional pressure switch and exhalant canal are respectively arranged on the both sides of shell, installation between itself and other parts is comparatively constant, and need to implement many places and seal, if its sealing means is generally on intake tunnel and exhalant canal, the individual seal groove placed for sealing ring is set, not only process inconvenience, and improve production cost.
Summary of the invention
For the deficiency that prior art exists, this utility model provides and a kind of prevents medium refluence, simple in construction, installation and pressure switch easy to process.
For achieving the above object, this utility model provides following technical scheme: a kind of pressure switch, include shell, shell is provided with intake tunnel, exhalant canal and for connecting the connection chamber of intake tunnel and exhalant canal, microswitch it is provided with in shell, microswitch be connected between chamber to be provided with the diaphragm driving microswitch to be turned on and off, it is characterized in that: described intake tunnel and exhalant canal parallel side-by-side are arranged on shell, intake tunnel includes water inlet end and water delivery end, exhalant canal includes link and water side, the water delivery end of intake tunnel is turned on by the link in connection chamber with exhalant canal, described shell is positioned at the water inlet end place of intake tunnel and is provided with installation step, installation step is arranged with sealing ring respectively.
Adopt technique scheme, intake tunnel and exhalant canal parallel side-by-side be arranged on shell, reduce the erection space of shell, and only need when installing an end face positioning instant can, easy for installation; Shell be positioned at intake tunnel water inlet end place arrange installation step be disposed to be easily installed, on installation step, the setting of sealing ring is then the sealing in order to keep installation place, prevent from revealing, and the installation of sealing ring without arranging mounting groove on shell, making processing more convenient, structure is more simple.
This utility model is further arranged to: shell is positioned at the water side place of exhalant canal and is provided with erecting bed terrace, and this erecting bed terrace place is arranged with sealing ring.
Adopting technique scheme, such setting further improves shell and implements sealing when installing with external component.
Below in conjunction with accompanying drawing, this utility model is further described.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of this utility model embodiment;
Fig. 2 is the structural representation of this utility model embodiment.
Detailed description of the invention
A kind of pressure switch as shown in Fig. 1 Fig. 2, include shell 1, shell 1 is provided with intake tunnel 11, exhalant canal 12 and for connecting the connection chamber 13 of intake tunnel 11 and exhalant canal 12, microswitch 3 it is provided with in shell 1, microswitch 3 be connected between chamber 13 to be provided with the diaphragm 2 driving microswitch 3 to be turned on and off, intake tunnel 11 and exhalant canal 12 parallel side-by-side are arranged on shell 1, intake tunnel 11 includes water inlet end 111 and water delivery end 112, exhalant canal 12 includes link 121 and water side 122, the water delivery end 112 of intake tunnel 11 turns on by connecting the link 121 in chamber 13 and exhalant canal 12, shell 1 is positioned at water inlet end 111 place of intake tunnel 11 and is provided with installation step 14, installation step 14 is arranged with sealing ring 4 respectively. adopt technique scheme, intake tunnel 11 and exhalant canal 12 parallel side-by-side be arranged on shell 1, reduce the erection space of shell 1, and only need when installing an end face positioning instant can, easy for installation, shell 1 be positioned at intake tunnel 11 water inlet end 111 place arrange installation step 14 be disposed to be easily installed, on installation step 14, the setting of sealing ring 4 is then the sealing in order to keep installation place, prevent from revealing, and the installation of sealing ring 4 without arranging mounting groove on shell 1, making processing more convenient, structure is more simple. it should be noted that only need to arrange a sealing ring 4 herein, the sealing of shell 1 and external component just can be protected.
In this utility model embodiment, in order to further improve sealing when being connected between shell 1 and external component, shell 1 is positioned at water side 122 place of exhalant canal 12 and is provided with erecting bed terrace 15, and this erecting bed terrace 15 place is arranged with sealing ring 4. The sealing ring 4 at this place also needs to install one.
