Description
Technical field
The utility model relates to a kind of air throttle, especially a kind of air throttle of independent air-supply rearging cage.
Background technique
The at present known structure that is used for to independent air-supply rearging cage (IVC) ventilation is to realize by a total ventilation pipe that is provided with valve, one termination of total ventilation pipe is led to atmosphere or oxygen unit is provided, the other end is provided with a plurality of branches, each airtight rearging cage is provided with the tubule of ventilating that should one of them branch of total ventilation pipe, tubule one end this house steward branch that is connected, the other end inserts in the rearging cage.By such structure, when the total ventilation tube valve was opened, gas injected tubule by total ventilation pipe branch, and directly was injected in the airtight rearging cage by tubule, made a plurality of rearging cages obtain gas simultaneously and injected.But the switch of this structure has only one and be located on the total ventilation pipe, and do not have the control corresponding switch on each rearging cage, so the rearging cage that can not effectively only take a breath at needs carries out, and causes the waste of resource, and can not effectively manage the oxygen density in the rearging cage.
Summary of the invention
In order to solve above-mentioned technical problem, the utility model provides a kind of air throttle that is installed on the independent air-supply rearging cage, can control gaseous enter this rearging cage of independently blowing.
The purpose of this utility model is achieved through the following technical solutions:
A kind of independent air-supply rearging cage air throttle, comprise an air throttle housing, described housing one end is provided with ventilating hole, the other end is provided with suction port, is provided with a piston that is used to control air inlet between described ventilating hole and the described suction port, and described piston rear end is connected with a push rod, be provided with the elastic component of a biases piston between described piston nose and the described ventilating hole, one sealing surface is arranged in the described housing, and described sealing surface matches with described piston, is used for being communicated with or cutting off described ventilating hole and suction port.
Further, described housing is provided with screw thread for one section, and described screw thread is with rotation set with matching outward, and this rotation set may command air throttle housing moves along its axis.
Again further, described push rod periphery is provided with the guide sleeve of this push rod of guiding.Be provided with stuffing box gland between described guide sleeve and described housing, described stuffing box gland sealing connects described housing and described guide sleeve.
Further, described sealing surface can be made into horizontal plane or plane of inclination.
The beneficial effects of the utility model are mainly reflected in: the air throttle good sealing effect, can reasonably use resource, simple in structure, manufacture cost is lower, processes also simple relatively.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Sectional view when being the utility model air throttle closure as Fig. 1;
As Fig. 2 is the sectional view of the utility model air throttle when opening.
Wherein:
1 housing, 3 screw threads, 5 rotation sets
7 springs, 9 stuffing box glands, 11 pistons
13 push rods, 15 guide sleeves, 17 baffle plates
19 sealing plates, 21 ventilating holes, 23 suction ports
25 sealing surfaces
Embodiment
The utility model has disclosed a kind of independent air-supply rearging cage air throttle, preferred forms of the present utility model as shown in Figure 1, this air throttle comprises an air throttle housing 1, this housing 1 can insert patchhole (not shown) with matching on the rearging cage, and the described patchhole of rotation set 5 sealings by matching with the set screw thread 3 of this housing 1 leading portion, and by screw thread 3 and rotation set 5 effects that are provided with on the housing 1, the 1 relative rearging cage Y motion of may command air throttle housing.Front end at housing 1 also is provided with a sealing plate 19, and the ventilating hole 21 that communicates with atmosphere or total ventilation pipe is arranged on the sealing plate 19, and the gas of required injection enters rearging cage from this ventilating hole 21.
A suction port 23 is arranged in the rear end of housing 1, and have a piston 11 to can be used as the switch of this suction port 23.In air throttle housing 1 inside a sealing surface 25 is arranged, sealing face 25 is used for 11 pairs of suction ports 23 of fitting piston and seals or open, wherein, sealing face 25 can form horizontal plane or plane of inclination, if wherein sealing surface 25 is set to horizontal plane, then can be after piston 11 to be opened, gas carries out with a certain amount of injection rearging cage; If sealing surface 25 is set to the plane of inclination, then can be when piston 11 to be opened, the injection rate that gas injects rearging cage increases gradually, and piston 11 also needs matching trim 25 to make corresponding adjustment in order to reach excellent sealing effect simultaneously.Sealing plate 19 forms a cavity with piston 11 in housing, there is a spring 7 to be arranged in the cavity, and be arranged between sealing plate 19 and the piston 11, and be resisted against sealing plate 19 and piston 11, make piston under the air throttle closed state, piston energy effective closure sealing surface 25, the rear end of piston 11 is connected with a push rod 13, this push rod 13 also can be shaped to one with piston 11, these push rod 13 peripheries are provided with the guide sleeve 15 of this push rod 13 of guiding, this guide sleeve 15 avoids this push rod 13 to move on the direction except that axially to greatest extent, makes structure more reliable.Be provided with a rubber system stuffing box gland 9 between peripheral and this guide sleeve 15 of housing 1 rear end, sealing cover 9 connects housing 1 and guide sleeve 15, and keeps sealing between housing 1 and the guide sleeve 15.At the other end of push rod 13, be provided with a baffle plate 17 that is used for against push rod 13 with push rod 13 separates mutually, this baffle plate places in the rearging cage.Under air throttle was in closed state, 17 on push rod 13 and baffle plate did not have active force.
As shown in Figure 1, when the described sealing surface 25 of above-mentioned spring 7 biases piston, 11 sealings, suction port 23 is closed, there is not active force between push rod 13 that is connected with piston 11 and the baffle plate 17, described air throttle is in closed state, when the total ventilation pipe is opened or ventilating hole 21 when contacting with gas, gas enters cavity the housing 1 from ventilating hole 21, but can not arrive in the rearging cage by suction port 23, and gas pressure acts on the piston 11, make piston 11 more can be against sealing surface 25 and cooperate sealing suction port 23.As shown in Figure 2, when needs in rearging cage during injecting gas, by rotary shell 1, make housing 1 move axially, thereby make push rod 13 abut to baffle plate 17 that baffle plate 17 will pass on the piston 11 against power by push rod 13 with respect to rotation set 5, the elastic acting force that this active force makes piston 11 overcome spring 7 moves forward, and throw off with sealing surface 25, suction port 23 is opened, and gas enters rearging cage.
