Description
Technical Field
The utility model belongs to the technical field of the liquid control switch, concretely relates to water flow switch.
Background
The water flow switch structure comprises a water inlet and outlet structure and an induction control device arranged on the water inlet and outlet shell, the induction control device is connected with a mechanical baffle in the shell, the water flow switch is used for circulation control of a water system, after water flow reaches a certain flow, the mechanical part baffle drives the mechanical part baffle to displace to drive a magnetic source to generate a magnetic control action output switch signal, otherwise, when the water flow in a pipeline is lower than a specific pressure, the magnetic core drives the magnetic source to reset to enable the sensor to output the signal for alarming under the action of a reset spring. The water flow switch plays an important role in an electric boost safety system. If the water flow switch is not found timely, high-temperature electrode breakage can be caused, and great loss is caused to production and equipment. However, the existing water flow switch has the following defects that the existing water flow switch is suitable for the situation that the water pressure changes suddenly under the condition that the water pressure ratio is stable, and when the water pressure is unstable, if a water tower type water supply is adopted, along with the continuous reduction of the water level, the pressure is gradually reduced, after the water inflow of the valve impacts the mechanical baffle device in the valve, the water flow scattering impact force is insufficient, the water flow can not well shift the mechanical baffle, the magnetic switch is driven to shift the sensor within the normal working range, and the sensitivity of the sensor is not well adjusted.
SUMMERY OF THE UTILITY MODEL
To the technical problem above, an object of the utility model is to provide a water flow switch.
Rivers switch, including water inlet, delivery port and the casing of setting between water inlet, delivery port, induction control device is installed to the casing, induction control device is connected with mechanical baffle, water inlet department installs the detachable bell, the bell macrostoma end is located the direction of coming water, the bell microcephaly end is located the direction of going out water, the bell macrostoma end border department has outside annular baffle, annular boss has on the water inlet inner wall, the annular baffle side of going out the water side pastes with annular boss mutually, the bell microcephaly end is 2mm with mechanical baffle's horizontal distance d.
The water inlet pipe is screwed into the water inlet to extrude and fix the annular baffle.
The width of the annular baffle is 1 mm.
The utility model is an improvement of the prior art, for example, after the water jacket of the electric boosting electrode is filled with water, the water jacket return pipe directly flows into the return water box through the water flow switch, the sensitivity position of the magnetic sensor of the water flow switch is required to be adjusted when in use, when the water inlet pressure has a normal fluctuation range, the water flow switch frequently gives an alarm and the magnetic sensor is not easy to adjust, because the water inlet of the water flow switch is larger than the mechanical transmission device of the magnetic switch of the water flow switch, after the water flow switch enters water, the water flow is dispersed and can not directly impact on the mechanical transmission device, because the pressure adjusting range is smaller because the water flow switch is unreasonably designed for water inlet, the improved water flow switch of the utility model, the water inlet is provided with the conical opening, the pressure of the inlet water is increased after passing through the conical opening, the pressure of the water flow switch is adjusted to be increased, and the control signal of the water flow switch is adjusted and controlled conveniently.
Compared with the prior art, the utility model, following beneficial effect has.
(1) The utility model is easy to adjust and control the signal when the water flow pressure fluctuates in the normal range;
(2) the utility model discloses a detachable construction, convenient improvement and installation.

Detailed Description
The invention will be further described with reference to the following examples and drawings.
As in fig. 1, 2, water flow switch, including water inlet 1, delivery port 7 and set up at water inlet 1, casing 6 between delivery port 7, induction control device 5 is installed to casing 6, induction control device 5 is connected with mechanical baffle 4, detachable bell mouth 3 is installed to 1 department of water inlet, 3 macrostoma of bell mouth are located the incoming water direction, 3 osctoma of bell mouth are located the water outlet direction, 3 macrostoma of bell mouth border department has outside annular baffle 9, annular boss 2 has on 1 inner wall of water inlet, the annular baffle 9 side of water outlet side pastes with annular boss 2 mutually, 3 microstoma of bell mouth and mechanical baffle 4's horizontal distance d ═ 2 mm.
As shown in figure 3, when in use, the water inlet 1 is screwed into the water inlet pipe 8 to extrude and fix the annular baffle 9.
The width of the annular baffle 9 is 1 mm.
The utility model discloses rivers switch after the improvement, the department installs the bell 3 at the inlet, and 3 back pressure increases of process bell of intaking, and rivers switch pressure adjustment grow has made things convenient for rivers switch's control signal adjustment control.
