Embodiment
Below in conjunction with Figure of description, the utility model is described in more detail.
As shown in Figure 1, the energy-conservation suction valve that the utility model provides, comprises cylinder 10, spool 30 and drive unit; Cylinder 10 offers the first through hole 111 and the second through hole 112; In cylinder 10, be provided with spool 30, spool 30 can do piston movement in cylinder 10.Spool 30 is provided with the interconnecting part 211 that can make the first through hole 111 and the second through hole 112 be communicated with in the time of valve opening.In cylinder 10, have third through-hole 114, spool 30 is provided with the breach 22 that can be communicated with third through-hole 114 in the time of valve closing, and cylinder 10 is also provided with the first passage 40 that can be communicated with third through-hole 114 in the time of valve closing.In cylinder 10, have fourth hole 201, drive unit is connected with spool 30 through fourth hole 201.
It should be noted that, said interconnecting part can have multiple set-up mode here, such as: can be the first groove 211 that hoop is offered on spool 30 as shown in Figure 1, 2; It can also be the second groove 212 of radially offering on spool 30 as shown in Figure 3.
In cylinder 10, also have third through-hole 114, on spool 30, have the breach 22 that can be communicated with third through-hole 114 in the time of valve closing, cylinder 10 also has the first passage 40 that can be communicated with third through-hole 114 and the second through hole 112 in the time of valve closing, and first passage 40 is communicated with the second through hole 112 and third through-hole 114 via the interior of cylinder 10.In addition, can also use external pipeline that the first pipeline 40 is connected with the second through hole 112.Even, can also use external pipeline that the first pipeline 40 is directly connected with gas compressing equipment.
Drive unit can comprise driving arrangement 601, can also comprise connecting rod 602.Wherein, driving arrangement can be that cylinder, oil hydraulic cylinder can also be that motor and gear match, and concrete Placement is as follows: the telescopic one end of driving arrangement can directly be connected with spool 30, can also be connected with spool 30 by connecting rod 602.
As shown in Figure 1, the telescopic one end of driving arrangement 601 is connected with spool 30 by connecting rod 602.In this kind of design, in cylinder 10, radially have fourth hole 201 along it, connecting rod 602 connects spool 30 through fourth hole 201.In the time that the piston rod of driving arrangement or hydraulic equipment is protruding, connecting rod 602 is with movable valve plug 30 to move in cylinder 10, until valve is opened completely.
As shown in Figure 2, the telescopic one end of driving arrangement 601 is directly connected with the end of spool 30, can push spool 30 in the interior movement of cylinder 10, until valve is opened completely.It should be noted that, in this kind of design, piston rod also can be connected with spool 30 by connecting rod 602.
As shown in Figure 1, 2, energy-conservation suction valve described in the utility model in off position under, interconnecting part is not between the first through hole 111 and the second through hole 112, spool 30 has cut off the connection between the first through hole 111 and the second through hole 112 completely, and air-flow can not flow in gas equipment through the second through hole 112 by interconnecting part from the first through hole 111.Under this state, third through-hole 114 exposes from the breach 22 on spool 30, is communicated with first passage 40.
As shown in Figure 4, energy-conservation suction valve described in the utility model is under opening state, interconnecting part is between the first through hole 111 and the second through hole 112, the first through hole 111 and the second through hole 112 are in connected state smoothly, and air-flow can be flowed in gas equipment through the second through hole 112 by interconnecting part by the first through hole 111.Under this state, spool 30 has blocked being communicated with of third through-hole 114 and first passage 40.
In process from closed condition to opening state, drive unit drives spool 30 to move in cylinder 10, until interconnecting part is while being placed between the first through hole 111 and the second through hole 112 completely, valve is opened completely.Now, gas can flow to gas equipment from throughput through the second through hole 112 swimmingly by the first through hole 111.
In the time of needs throttle down, restart drive unit, band movable valve plug 30 is in the interior movement of cylinder 10, until spool 30 cuts off the connection of the first through hole 111 and the second through hole 112, valve closes completely.
Need to stress, in actual use, third through-hole 114 is connected with external air source, and in the time that gas equipment gas consumption reduces, valve starts to close gradually.In this process, third through-hole 114 is exposed in breach 22 gradually, thereby third through-hole 114 is communicated with the second through hole 112 by first passage 40.Now, gas unnecessary in gas equipment, just from the second through hole 112, is back to external air source by first passage 40, third through-hole 114, reduces the air total amount of compressed discharge, realizes energy-conservation object.
In addition, owing to being that the connection that relies on spool 30 to cut off completely between the first through hole 111 and the second through hole 112 realizes throttle down, therefore, should ensure that the gap between spool 30 and cylinder 10 should be as much as possible little.Therefore, on cylinder 10 inwalls, be covered with seal ring 90.Certainly, this seal ring 90 also can be laid on spool 30 outer walls.
More than statement is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, within these also should be considered as protection domain of the present utility model.
