Description
Technical field
The utility model belongs to pressure switch field, more particularly to steam pressure switch.
Background technology
Steam pressure switch is a kind of switch module for being arranged on and realizing fast opening and closing in steam pipework using steam pressure.
The structure for the steam pressure switch sold and used in the market is mostly by base, retainer plate, seal, pressure
Power shell fragment, movable jacking block, upper lid, microswitch and screw rod etc. are formed, and microswitch, which also includes one, to reset movable jacking block
Spring, spring base and pad, when steam pressure be more than pressure shell fragment make its arch upward upwards deformation after, you can promote movable top
Block moves upwards, touches microswitch and opens；When steam pressure is less than pressure shell fragment, movable top is promoted using spring force
Block reset simultaneously departs from microswitch.
It is inconvenient for use but the steam pressure switch structure of this structure is more complicated.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides steam pressure switch, mainly solves present steam
Pressure switch construction is more complicated, it is inconvenient for use the problem of.
Technical scheme is used by the utility model：
Steam pressure switch, including base, switch body are connected with the base, the base bottom is provided with passage, institute
State chassis interior and be correspondingly provided with diaphragm group with the passage；Support plate is provided with the switch body, the support plate is provided with top, institute
State in switch body and be provided with moving contact, static contact and dynamic touch panel, described dynamic touch panel one end is correspondingly arranged and is provided with the moving contact
The static contact, the top are correspondingly arranged at the dynamic touch panel lower end；The switch body is provided with fine motion seat, on the fine motion seat
Be provided with screw press provided with first through hole, in the first through hole, the screw press middle-end and support plate screw thread cooperation and
Bottom is correspondingly arranged with the diaphragm group.
The beneficial effects of the utility model are：The utility model provides steam pressure switch, and its diaphragm group is by passage
Steam pressure rise after can deform upon, promote dynamic touch panel by coming directly towards, moving contact is contacted or disconnect static contact
（Depending on switch is normally closed or normally opened）, it is simple in construction, it is easy to use.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model one embodiment.
Fig. 2 is enlarged diagram at Figure 1A.
Fig. 3 is the schematic perspective view of the utility model one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：As illustrated, steam pressure switch, including base 1,
Switch body 2 is connected with the base, the base bottom is provided with passage 11, and the chassis interior is corresponding with the passage 11 to be set
There is diaphragm group 7；Support plate 21 is provided with the switch body 2, the support plate 21 is provided with top 211, is provided with the switch body 2 dynamic
Contact 31, static contact 32 and dynamic touch panel 33, described dynamic one end of touch panel 33 are correspondingly arranged with the moving contact and are provided with the stationary contact
Head, the top are correspondingly arranged at the dynamic touch panel lower end；The switch body 2 is provided with fine motion seat 4, and the fine motion seat 4 is provided with
First through hole 41, the first through hole 41 is interior to be provided with screw press 42, and the middle-end of screw press 42 is matched somebody with somebody with the support plate screw thread
Close and bottom is correspondingly arranged with the diaphragm group 7.The utility model provides steam pressure switch, and its diaphragm group is by passage
Steam pressure can deform upon after rising, and promote dynamic touch panel by coming directly towards, moving contact is contacted or disconnect static contact（Take
It is certainly normally closed or normally opened in switch）, it is simple in construction, it is easy to use.By taking normally closed switch as an example, after pressure becomes strong on support plate
Rise top top pressure and move touch panel, and then drive moving contact that open circuit is implemented separately with static contact, dynamic touch panel here can be with one end with opening
Internal wall connection is closed, one end is corresponding with static contact and is provided with moving contact, and the top, which is arranged under dynamic touch panel, to be convenient to push up when rising
Contact is started, can also be connected as one of embodiment movable contact spring one end with the one of plug, another phase of static contact and plug
Connection, such as L poles and N poles, stopping heating after disconnection, then the pressure of steam dies down, and diaphragm deformation recovers, and support plate sets back,
Dynamic touch panel return, moving contact also return.Can rise or decline by screw press needs the degree of deformation to adjust diaphragm,
And then to adjust the intensity of pressure being adapted to, use more facilitates.
In the present embodiment, as illustrated, being engaged by clamping on the fine motion seat has protective cover 5, the protective cover is used to hide
Cover the first through hole.Prevent foreign matter from entering in first through hole, water proof and dust proof, using effect is more preferably.
In the present embodiment, as illustrated, the fine motion seat 4 is provided with bulge loop 43, the bottom of protective cover 5 is provided with clamping
Ring 51, the clamping ring inwall are engaged by clamping with the bulge loop outer wall.Dismounting is more convenient, and using effect is more preferably.
In the present embodiment, as illustrated, also including hollow connector 6 and joint 9, the connector includes baffle ring 61
With connecting tube 62, the baffle ring 61 is in the base and baffle ring stops cooperation with the passage 11, and the connecting tube passes through
The passage is outer located at the base and is connected with the joint screw thread.Joint is used to be connected with pipeline, by connecting tube with connecing
Head connection.
In the present embodiment, as illustrated, be additionally provided with the baffle ring 61 annular withhold wall 611, the diaphragm group 7 is wrapped
Lower diaphragm 71 and upper diaphragm 72 are included, the screw press 42 is pressed on the upper surface of the upper diaphragm, and the lower diaphragm is provided with
