Abstract
The utility model provides an improved high water pressure switch which is provided with an upper shell, a middle shell and a bottom shell and is installed into a box shape through a plurality of bolts, wherein the upper shell is provided with a water pipe which is internally provided with a water pressure hole; the middle shell is internally provided with a containing cavity for containing corresponding elements; the bottom shell is internally provided with a first cavity and a second cavity; the first cavity is internally provided with a spring; the second cavity is internally provided with a microswitch; a pressing cover is arranged at one end edge of the spring and is correspondingly and movably contacted with a lever arranged above the microswitch; and the lever is contacted movably through a lug of the pressing cover, so that the lever can be prevented from deforming easily due to long distance, and a water pressure interval well preset by the switch can not change for long time.
Description
Technical field
The utility model relates to a kind of hydraulic pressure switch, particularly relating to a kind of modified model water under high pressure compresses switch, main by spring adjustment (adjusting) lever in the switch and the spacing between the button, avoid the lever distortion and the deviation spacing that occurs contacting, thereby influence the connection of sensitive switch with sensitive switch.
Background technology
The patent No. is 200920116050.0 high hydraulic pressure switch, comprise base, loam cake, diaphragm, the high pressure pressing plate, the high pressure springboard, sensitive switch, the corresponding diaphragm portion in high pressure pressing plate bottom forms movable chamber, be provided with the holder that is inverted T shape in the movable chamber, holder upper end and high pressure springboard lower end close neighbour, the upper surface close neighbour of holder bottom and diaphragm, ledge on its high pressure springboard more of the prior art removes, the holder that is inverted T shape is set between high pressure springboard and diaphragm, because the bottom area of holder is just in time consistent with the diaphragm area of below, in water enters into the hydraulic pressure chamber of diaphragm below, make on the diaphragm deformation and push up, promote to move on the holder, holder makes the action of high pressure springboard again, touch the switch contact of sensitive switch, because diaphragm deformation is normal, not fragile, and the holder upper end is circular-arc, little with high pressure springboard contact area, active force is big, makes the work of high pressure springboard good.
Yet, adopt the problem of described high pressure springboard to be that plate height degree is longer, diaphragm is directly applying pressure under the roof pressure of high hydraulic pressure on the high pressure springboard, press microswitch push-button by this high pressure springboard, but, in the course of time, described high pressure springboard can be owing to be subjected to external force and flexural deformation, and crooked direction majority is equidirectional direction in the diaphragm roof pressure, causes the spacing of diaphragm and high pressure springboard to become big, makes the interval of the hydraulic pressure pressure that switch is scheduled to be easy to generate variation.
Summary of the invention
For addressing the above problem, the utility model provides a kind of modified model water under high pressure to compress switch, it is provided with upper casing, mesochite and drain pan, be mounted to the box body shape by some screws, wherein, described upper casing is provided with water pipe, be provided with the hydraulic pressure hole in the water pipe, be provided with containing cavity in the described mesochite, have the usefulness of ccontaining respective element, be provided with first cavity and second cavity in the described drain pan, wherein, mounting spring in described first cavity is installed sensitive switch in second cavity, and an end of described spring is provided with gland, and this gland contacts with the corresponding activity of lever that is installed in the sensitive switch top.
Wherein, described first cavity and described second cavity be positioned at drain pan about each position on one side.
Further, the side of described gland is provided with projection, and nationality is by this projection engagement lever.
Wherein, diaphragm is installed in corresponding position, described hydraulic pressure hole, utilizes described diaphragm by pasting the described gland of roof pressure.
Wherein, described lever is provided with lug, is installed in the mesochite by described lug, forms up and down state.
The other end of described spring more is equipped with collet, is corresponding with the pressure regulating screw that is installed in described drain pan bottom.
The beneficial effects of the utility model are, resilience force by spring, make diaphragm roof pressure gland to pressing down, and the movable engagement lever of the projection that sees through gland, thereby avoid lever owing to the easy deformation phenomenon appears in long distance, so that extraordinary keeping between the predetermined hydraulic pressure pressure area of switch do not have variation phenomenon for a long time.

Embodiment
See also 1 shown the utility model, it is provided with upper casing 1, mesochite 2 and drain pan 3, be mounted to the box body shape by some screws 6, as Fig. 2, shown in Figure 3, described upper casing 1 is provided with water pipe 11, be provided with hydraulic pressure hole 12 in the water pipe 11, be provided with containing cavity 21 in the described mesochite 2, usefulness with ccontaining respective element is provided with first cavity 31 and second cavity 32, wherein in the described drain pan 3, mounting spring 4 in described first cavity 31, sensitive switches 5 are installed in second cavity 32, and an end of described spring 4 is provided with gland 22, this gland 22 contacts with the lever 23 corresponding activities that are installed in sensitive switch 5 tops.
Further combined with Fig. 2, shown in Figure 3, and carefully state concrete structure between each parts, described first cavity 31 and described second cavity 32 be positioned at drain pan 3 about each position on one side, the side of described gland 22 is provided with projection 221, nationality is by these projection 221 engagement levers 23.
Again, diaphragm 12 is installed in 12 corresponding positions, described hydraulic pressure hole, utilizes described diaphragm 12 by pasting the described gland 22 of roof pressure, and described lever 23 is provided with lug 231, is installed in the mesochite 2 by described lug 231, forms up and down state.
The other end of described spring 4 more is equipped with collet 24, is corresponding with the pressure regulating screw 7 that is installed in described drain pan 3 bottoms, so, when pressure regulating screw 7 is screwed into toward in more, then be the spring 4 that compresses more between collet 24 and the gland 22, so that need higher hydraulic pressure pressure, could roof pressure gland 22.
Therefore, in conjunction with Fig. 3, shown in Figure 4, the water pipe 11 of outer water receiving sees through hydraulic pressure hole 12 and roof pressure diaphragm 12, and diaphragm is heaved for the rubber material, forms the power of downward roof pressure gland 22, at this moment, spring 4 is tightened up, and projection 221 is also followed gland 22 toward pressing down, until by these projection 221 engagement levers 23, press down by lever 23 pressurizeds are also past, finally, realize the energising purpose by the button of lever 23 contact sensitive switches 5, and when hydraulic pressure stops, gland 22 can reset according to the elastic force of spring 4, at this moment, lever 23 is because pressurized not, and utilizes the fulcrum activity of lug 231, make one side of lever 23 tilt to be upturned, as shown in Figure 3.
According to the above description, and in conjunction with the accompanying drawings as the utility model better embodiment, right, other equivalent execution mode of the present utility model is not limited thereto, understand by described concrete enforcement, above-mentioned execution mode has disclosed concrete function of the present utility model and architectural characteristic.
