Below with reference to accompanying drawing, describe the pilot-operated type control valve assembly according to the embodiment of the present invention in detail.
As shown in Figure 1, the pilot-operated type control valve assembly according to the embodiment of the present invention, comprising: pilot valve 100, diaphragm 200, elastic component 300 and solenoid valve 400.
Specifically, in pilot valve 100, be limited with valve pocket 101.Diaphragm 200 is located in valve pocket 101 valve pocket 101 is divided into the first cavity 1011 and the second cavity 1012.Diaphragm 200 is provided with the damping hole 201 that is communicated with the first cavity 1011 and the second cavity 1012.
On pilot valve 100, also there is suction tude 102, steam outlet pipe 103, pneumatic tube 104 and outlet pipe 105.Wherein, the second end of suction tude 102 second ends (as shown in Figure 1 the right-hand member of suction tude 102) and steam outlet pipe 103 (as shown in Figure 1 the upper end of steam outlet pipe 103) is communicated with the second cavity 1012 respectively.The first end of pneumatic tube 104 (as shown in Figure 1 the lower end of pneumatic tube 104) is communicated with the first cavity 1011, and the first end of outlet pipe 105 (as shown in Figure 1 the left end of outlet pipe 105) is communicated with steam outlet pipe 103.
Elastic component 300 is located in valve pocket 101 and is connected often to promote the second end of diaphragm 200 sealing steam outlet pipes 103 with diaphragm 200.
Solenoid valve 400 has suction port 401 and air outlet 402.The second end of suction port 401 and pneumatic tube 104 (as shown in Figure 1 the upper end of pneumatic tube 104) is connected and the second end of air outlet 402 and outlet pipe 105 (as shown in Figure 1 the upper end of outlet pipe 105) is connected so that pneumatic tube 104 is communicated with outlet pipe 105.
Advantageously, pilot valve 100 can be open type/normal close type pilot valve.Solenoid valve 400 can be open type/normal close type two-bit triplet solenoid valve.Certainly, solenoid valve 400 is not limited to two-bit triplet solenoid valve, can be also the other forms of valves such as manually operated valve, hydraulic operated valve, pneumatic valve.
The pilot valve 100 of take below is simply described according to the working procedure of pilot-operated type control valve assembly of the present invention as normal close type two-bit triplet solenoid valve as example as normal close type and solenoid valve 400.
During original state, pilot valve 100 is in closed condition.Under the active force of elastic component 300, diaphragm 200 moves downward to seal the second end of steam outlet pipe 103, thereby makes the pathway closure between suction tude 102 and steam outlet pipe 103.
Working state: solenoid valve 400 electric before, with the gas of certain pressure, from suction tude 102, enter, arrive the second cavity 1012, gas enters the first cavity 1011 by damping hole 201.Now, the second cavity 1012 equates with the air pressure of the first cavity 1011, and the suffered pressure of diaphragm 200 upper and lower surfaces also equates.Under the active force of elastic component 300, pilot valve is in closed condition.
Solenoid valve 400 electric after, the suction port 401 of solenoid valve 400 is connected with air outlet 402, the gas of the first cavity 1011 is by pneumatic tube 104, suction port 401, air outlet 402 and outlet pipe 105, and then discharges from steam outlet pipe 103.Make like this air pressure of the first cavity 1011 reduce rapidly, because the latus rectum of damping hole 201 is very little, the gas of the second cavity 1012 can not reach the first cavity 1011 by damping hole 201 in time, thereby makes between the second cavity 1012 and the first cavity 1011 mineralization pressure poor.Due to the existence of pressure difference, the pressure of the lower surface of diaphragm 200 is greater than the pressure of upper surface, and diaphragm 200 just moves upward, and diaphragm 200 and the second end of steam outlet pipe 103 are departed from, thus being communicated with between suction tude 102 and steam outlet pipe 103.
According to the pilot-operated type control valve assembly of the embodiment of the present invention, will on diaphragm, be provided with damping hole, simple in structure, inspection and maintenance is more efficient and convenient.
According to an example of the present invention, on pilot valve 100, be also provided with blow-down pipe 106.On solenoid valve 400, be also provided with the drain 403 being communicated with blow-down pipe 106.Thus, after solenoid valve 400 dead electricity, unnecessary gas can be discharged by blow-down pipe 106.
According to an example of the present invention, described pilot-operated type control valve assembly also comprises diaphragm frame 500.Diaphragm frame 500 is located between elastic component 300 and diaphragm 200.Thus, can avoid contacting such as between the elastic component 300 of spring and diaphragm 200, between elastic component 300 and diaphragm 200, play buffer function, can extend the working life of diaphragm 200.
According to an example of the present invention, suction tude 102 is formed on the sidewall of pilot valve 100 and steam outlet pipe 103 is formed on the diapire of pilot valve 100.Advantageously, the second end of steam outlet pipe 10 has the flange 1031 that stretches into the second cavity 1012, has the fin 202 suitable with flange 1031 on diaphragm 200.Thus, can make 200 pairs of steam outlet pipes 103 of diaphragm there is better sealing process.
According to an example of the present invention, the first cavity 1011 is roughly frustoconic shape.For better protection diaphragm 200 can be not damaged when working, also can on the first cavity 1011, design gas channeling groove according to actual conditions.Certainly, the shape of the first cavity 1011 is also not limited to frustoconic shape, for example, can be the cavity with arc surface or other form curved surfaces.
At this, it should be noted that, as shown in Figure 1, in order to guarantee according to the tightness of pilot-operated type control valve assembly of the present invention, can between pilot valve 100 and solenoid valve 400, be provided with valve pad 600, this is understandable for the person of ordinary skill of the art.
According to the pilot-operated type control valve assembly of the embodiment of the present invention, due to damping hole is located on diaphragm, make overall structure simpler, inspection and maintenance is also more convenient
In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiments or example.
Although illustrated and described embodiments of the invention above, be understandable that, above-described embodiment is exemplary, can not be interpreted as limitation of the present invention, those of ordinary skill in the art can change above-described embodiment within the scope of the invention in the situation that not departing from principle of the present invention and aim, modification, replacement and modification.
