Abstract
The utility model discloses a four linkage air pressure switch which comprises a base. The base is provided with an air inlet hole, four air outlet holes and four air pressure switches. Every air outlet hole is respectively communicated with the air inlet hole, the four air pressure switches are connected with air outlet ends of the four air outlet holes respectively, and a humidity sensor is fixed at the tail end of a gas channel communicated with the air inlet hole in the base. The bottom end of the base is provided with a draining port communicated with the gas channel, and the draining port is provided with a detachable connection structure in sealed matching with a draining plug. After the humidity sensor and the draining port communicated with the air inlet hole are arranged on the base, when a vehicle is used normally, the draining port is plugged with the draining plug; when accumulated water exists in the base, accumulated water conditions are known through the humidity sensor; and when the accumulated water needs removing, the draining plug is dismantled, a brake is stepped on, compressed gas can blow the accumulated water in an air inlet pipe and the air pressure switch base out of the draining port, other parts do not need dismantling any longer, and the four linkage air pressure switch is extremely simple and convenient to maintain.
Description
Technical field
The utility model relates to a kind of baroswitch, relates in particular to a kind of tetrad baroswitch.
Background technology
Automobile-used baroswitch is a kind of control element in the vehicle launch control path, and it generally is to fix by the baroswitch seat of special use when use installing, and is communicated with air inlet pipe on being connected source of the gas by the gas passage in the baroswitch seat.At present, automobile-used baroswitch seat has two baroswitch pedestals (being that two baroswitches can be installed on the pedestal) and two kinds of forms of all the people present's baroswitch pedestal (four baroswitches can be installed on the pedestal), and what existing most of vehicle used is two baroswitch pedestals.Its structure is, comprise: pedestal, this pedestal is provided with induction opening and two air gates and pedestal mounting hole, air gate is used for installing baroswitch, each air gate is communicated with induction opening respectively, and the admission port position of induction opening also is provided with threaded joints, is used for the tapped bore connection structure to be converted to have externally threaded connector structure by a M18 adaptor union is installed, with with the threaded connection hole of existing air inlet pipe coupling, and then being communicated with of realization and air inlet pipe.Because the induction opening in this baroswitch seat is a blind hole, vehicle in use for some time, gas is stopped and is accumulated in the endotracheal water of brake in the system and accumulate over a long period and will overflow in the baroswitch pedestal, thereby influences the break-make of baroswitch, causes the vehicle brake deleterious; During the maintenance draining, must be that the professional pulls down air inlet pipe, and the switch pedestal is unloaded and could pour out the ponding in the pedestal from car body that maintenance procedures is loaded down with trivial details, work capacity is big, efficient is low.
The utility model content
The purpose of this utility model is to provide a kind of ponding that can find timely in the pedestal, and the baroswitch seat of getting rid of rapidly.
For achieving the above object, the utility model adopts following technical scheme: a kind of tetrad baroswitch, comprise pedestal, pedestal is provided with induction opening, four air gates and four baroswitches, each air gate is communicated with induction opening respectively, four baroswitches are connected to the outlet side of four air gates, and the end of the gas passage that is communicated with induction opening in the described pedestal is fixed a humidity sensor.
Described pedestal bottom is provided with the discharge port that is communicated with gas passage, has on the discharge port for the structure that removably connects that is sealed and matched with the draining plug.
The utility model pedestal arrange humidity sensor and with discharge port that induction opening is communicated with after, when vehicle normally uses, discharge port adopts in the draining shutoff, and ponding is arranged in the pedestal, learns the ponding situation from humidity sensor, when needs are got rid of, pull down the draining plug, step on service brake, pressure gas can blow out the ponding in air inlet pipe and the baroswitch pedestal from discharge port, and need not dismantle other parts again, keep in repair very easy.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, pedestal; 2, induction opening; 3, air gate; 4, baroswitch; 5 humidity sensors; 6, discharge port.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, a kind of tetrad baroswitch as shown in Figure 1, comprise pedestal 1, pedestal 1 is provided with induction opening 2, four air gates 3 and four baroswitches 4, each air gate 3 is communicated with induction opening 2 respectively, four baroswitches 4 are connected to the outlet side of four air gates 3, and the end of the gas passage that is communicated with induction opening 2 in the described pedestal 1 is fixed a humidity sensor 5.
Induction opening 6 on the pedestal 5 is positioned at the left side of pedestal 5, what be communicated with this admission port is gas passage, gas passage extends to the air extractor duct of low order end always, the inside face of discharge port 8 is provided with negative thread, when installing and using, be used for spinning draining plug with this discharge port of shutoff, and when the needs draining again row pull down, load onto again after the draining and get final product.
Claims (2)
1. tetrad baroswitch, comprise pedestal, pedestal is provided with induction opening, four air gates and four baroswitches, each air gate is communicated with induction opening respectively, four baroswitches are connected to the outlet side of four air gates, it is characterized in that: the end of the gas passage that is communicated with induction opening in the described pedestal is fixed a humidity sensor.
2. tetrad baroswitch according to claim 1, it is characterized in that: described pedestal bottom is provided with the discharge port that is communicated with gas passage, has on the discharge port for the structure that removably connects that is sealed and matched with the draining plug.
