Abstract
A throttling-device of pneumatic mechanism, which comprises an air pipe, a throttle valve installed in the cavity of the air pipe. Air throttling holes are opened along the center line of the throttle valve. The air flow passage before entering the air throttle holes are wide, when air flow arrives at the throttling holes, local resistance will be produced owing to reduction of the section area and the purpose to reduce flow rate can be achieved by this local resistance with proper size. The structure of the throttle valve is simple which can reduce the cost. Besides, the throttle valve can be inserted directly into the air pipe of the actuating element for safe operation which is simple to utilize and convenient for maintenance, and can be used in situations where throttling is required without necessity for frequent adjustment of flow rate.
Description
Technical field
The utility model relates to a kind of throttling arrangement of pneumatic mechanism.
Background technology
Background technology is that example illustrates with the throttling arrangement that is applied on the air-jet loom.
Yarn penetrates from the storage latitude drum rear portion of air-jet loom, deliver in the nozzle then, only need less pressure to realize this action and storage latitude drum is inner, this need reduce to enter the gas flow in the storage latitude drum usually, promptly on the tracheae that leads to storage latitude drum, throttling arrangement is set, in the prior art, usually in the exit of the source of the gas parts of loom needle-valve is installed, the intubate of giving vent to anger that will be fixed on again on the needle-valve is inserted on the gas-tpe fitting that leads to storage latitude drum, because needle-valve is that threaded engagement is connected with the source of the gas parts, so source of the gas and the supporting use of needle-valve palpus, this causes the use cost of needle-valve too high, it is also cumbersome to detect maintenance, and for not needing to regulate the air-jet loom of controlling out throughput, the control valve on the needle-valve has then caused cost waste.
From top example as can be seen, often adjust in the pneumatic mechanism of gas flow not needing, adopt existing throttling arrangement cost too high, detect the maintenance trouble, so be difficult to promote the use of.
Summary of the invention
The utility model purpose provides a kind of throttling arrangement of pneumatic mechanism, its simple in structure, escapable cost.
The technical solution of the utility model is: a kind of throttling arrangement of pneumatic mechanism, and it comprises tracheae, be inserted in the choke valve in the inner chamber of described tracheae, the direction of axis line of described choke valve has the throttling passage.
Described choke valve comprises at the valve afterbody of choke valve one end, at the valve head of choke valve the other end, valve body between described valve head and valve afterbody, the diameter of described valve head is greater than the diameter of valve body, described valve head is positioned at the tracheae outside, and described valve body and valve afterbody are arranged in the inner chamber of tracheae.
The diameter of described valve head is greater than the interior diameter of tracheae, and the diameter of described valve head is also less than the overall diameter of tracheae.
Form interference fit between at least one section of described choke valve and the tracheae.
Form interference fit between described valve afterbody and the tracheae.
The diameter of described valve body is less than or equal to the interior diameter of tracheae.
The utility model compared with prior art has following advantage:
In the inner chamber of tracheae, plug in choke valve, has the throttling pore on this choke valve, the gas channel broad of air-flow before entering the throttling pore, when arriving in the throttling pore, air-flow then is subjected to local resistance owing to sectional area diminishes, reach the purpose that reduces flow by this sizeable local resistance, and choke valve is simple in structure, can reduce cost, and directly choke valve is inserted in the tracheae and can uses safely, its use is more convenient, can detect maintenance easily and choke valve taken out from tracheae.
Description of drawings
Accompanying drawing 1 is a main cutaway view of the present utility model;
Wherein: 1, tracheae; 2, choke valve; 3, valve body; 4, valve afterbody; 5, valve head; 6, throttling pore.
The specific embodiment
Referring to accompanying drawing 1, a kind of throttling arrangement of pneumatic mechanism, it comprises tracheae 1, be inserted in the choke valve 2 in the inner chamber of described tracheae 1, and the axial line place of described choke valve 2 has throttling pore 6, and described choke valve 2 is processed by the stainless steel of anti-corrosion or aluminum component, logical part.
Described tracheae 1 is made by flexible pipe, and flexible pipe has certain harmomegathus performance; Described choke valve 2 comprises at the valve afterbody 4 of an end of choke valve 2, the valve head 5 in the other end of choke valve 2, the valve body 3 between described valve head 5 and valve afterbody 4, the diameter of described valve head 5 is greater than the diameter of valve body 3, described valve head 5 is positioned at valve head host cavity 4, and described valve body 3 and valve afterbody 4 are arranged in the inner chamber of tracheae 1.
The diameter of described valve head 5 is greater than the interior diameter of tracheae 1, and the diameter of described valve head 5 is also less than the overall diameter of tracheae 1, and the end chucking of valve head 5 and tracheae 1 like this can be at the axial location choke valve 2 of tracheae 1.
Utilize the harmomegathus performance of tracheae 1, make and form interference fit between one section of described choke valve 2 or multistage and the tracheae 1, in the embodiment shown in Figure 1, described valve afterbody 4 forms interference fit with the inwall of tracheae 1, can strengthen the tight steadiness of choke valve 5 and tracheae 1 combined installation.
The diameter of described valve body 3 is less than or equal to the interior diameter of tracheae 1, makes valve body 3 can be housed in the inner chamber of tracheae 1.
The utility model is applied on the pneumatic means, tracheae 1 is the part of pneumatic means, this tracheae 1 leads to pneumatic action element, air-flow enters the throttling pore 6 from the right-hand member (with reference to accompanying drawing 1) of valve head 5, because the gas channel of air-flow before entering throttling pore 6 is bigger, so air-flow runs into local pressure when entering in the throttling pore 6, make air-flow by entering in the action element in the elongated throttling pore 6, so throughput reduces, air pressure also reduces thereupon, the sectional area of passage that like this can be by the air-flow process changes realizes the throttling purpose, thereby satisfies the pressure demand in the execution action element of pneumatic mechanism.
