Abstract
The utility model discloses a gas valve for soil pick -up car, including disk seat, piston and case, the disk seat is equipped with piston chamber and spool chamber, piston chamber and spool chamber intercommunication, piston chamber top, bottom all are equipped with the air vent, communicate outside the air vent of the vacuum machine of the air vent at piston chamber top or the air vent of bottom and soil pick -up car or gas compressor intercommunication, piston chamber bottom or the air vent at top and the piston chamber, the spool chamber is equipped with inlet port and venthole, and this inlet port and venthole pass through the spool chamber, the inlet port utilizes equipment UNICOM with air supply UNICOM, venthole and gas, the piston suit is in the case, case bottom or top are arranged in the spool chamber.
Description
Technical field
The utility model relates to a kind of environmental sanitation cleaning equipment, particularly a kind of gas valve for suction-type sewer scavenger.
Background technique
The gas valve of current use, the gate valve of gas valve is generally adopt digital control scheme to open or manual unlatching, and this gas valve is applied on suction-type sewer scavenger, because suction-type sewer scavenger does not have this gas valve and the supporting control system of suction-type sewer scavenger miscellaneous equipment, also be difficult to installation and this gas valve and the supporting control system of suction-type sewer scavenger miscellaneous equipment maybe cannot be installed, so that inefficiency, inconvenient.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of easy to use, gas valve for suction-type sewer scavenger that working efficiency is high.
In order to solve the problems of the technologies described above, the gas valve for suction-type sewer scavenger of the present utility model, comprises valve seat, piston and spool, and described valve seat is provided with piston cavity and spool chamber; Described piston cavity is communicated with spool chamber; Described piston cavity top, bottom are equipped with vent, the vacuum machine of the described vent at piston cavity top or the vent of bottom and suction-type sewer scavenger or gas compressor is communicated with, the vent at vent bottom piston cavity or top is communicated with outward with piston cavity; Described spool chamber is provided with inlet hole and air outlet hole, and this inlet hole and air outlet hole are by spool chamber UNICOM; Described inlet hole and source of the gas UNICOM, air outlet hole and gas utilize equipment UNICOM; Described piston sleeve is loaded on spool; Described spool bottom or top are placed in spool chamber.
Described outer surface of piston is also provided with seal ring.
Also comprise Regulation spring, described Regulation spring is placed in piston head or bottom, and this Regulation spring one end is connected with piston, the other end is connected with piston cavity inwall, for piston return.
The motor exhaust relief opening UNICOM of described inlet hole and suction-type sewer scavenger.
Adopt structure of the present utility model, owing to comprising valve seat, piston and spool, during use, rise in piston cavity at the vacuum machine of suction-type sewer scavenger or the gas pressure lower piston of gas compressor or decline, interlock spool rises at spool chamber or declines, namely inlet hole and air outlet hole are by spool chamber UNICOM, and the gas of source of the gas can be delivered to gas and utilize equipment.Close vacuum machine or the gas compressor of suction-type sewer scavenger when needing to close gas valve, piston declines in piston cavity, and interlock spool declines at spool chamber and cuts off inlet hole and air outlet hole, and namely close gas valve, easy to use, working efficiency is high.
Because outer surface of piston is also provided with seal ring, to make the sealing effect of piston and piston cavity better, use more convenient.
Owing to also comprising Regulation spring, described Regulation spring is placed in piston head or bottom, and this Regulation spring one end is connected with piston, the other end is connected with piston cavity inwall, for piston return, to make piston return in piston cavity more coordinate, operates simpler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, the gas valve for suction-type sewer scavenger of the present utility model, comprises valve seat 9, piston 7 and spool 5, and described valve seat 9 is provided with piston cavity 8 and spool chamber.Piston cavity 8 is communicated with spool chamber.Piston cavity 8 top, bottom are equipped with vent 2.Vent 2 or the vent of bottom at piston cavity 8 top are communicated with the vacuum machine of suction-type sewer scavenger or gas compressor, the vent at vent 2 bottom piston cavity 8 or top is communicated with piston cavity 8 is outer.Spool chamber is provided with inlet hole 4 and air outlet hole 6, and this inlet hole 4 and air outlet hole 6 are by spool chamber UNICOM.The motor exhaust relief opening UNICOM of inlet hole 4 and suction-type sewer scavenger, air outlet hole and gas utilize equipment UNICOM.Inlet hole 4 also can be set in spool 5 with other source of the gas UNICOM piston 7.Spool 5 bottom or top are placed in spool chamber.
In order to make the sealing effect of piston and piston cavity better, use more convenient, piston 7 outer surface is also provided with seal ring 3.
In order to make piston return in piston cavity more coordinate, operation is simpler, and also comprise Regulation spring 1, Regulation spring 1 is placed in piston 7 top or bottom, and this Regulation spring 1 one end is connected with piston, the other end is connected with piston cavity 8 inwall, for piston 7 return.
