Abstract
The utility model discloses a diaphragm-type one-way cylinder. The defects that the conventional one-way cylinder product needs to be maintained regularly and has narrow application field are overcome. The diaphragm-type one-way cylinder comprises a pot-shaped cylinder body and a basin-shaped cylinder cover. The cylinder body and the cylinder cover are fixedly connected by a plurality of bolts. The center of the cylinder cover is provided with a gas connection port. An elastic diaphragm is embedded at the edges of the cylinder body and the cylinder cover. The end part of the cylinder body is provided with a guide sleeve. A piston rod is arranged in the guide sleeve. One end of the piston rod extends into an accommodating cavity formed by the cylinder and the diaphragm and the other end of the piston rod extends out of the guide sleeve. The end part of the piston rod, which is adjacent to the diaphragm, is provided with a spring seat. A spring is arranged between the spring seat and the inner wall of the cylinder. The outer surface of the guide sleeve is provided with a pair of set screw nuts. The product has the advantages of simple and convenient structure, novel design and high safety and can be widely applied to the pneumatic control fields such as ship heavy industry, petrochemical engineering, medical equipment, engineering machinery and the like.
Description
Technical field
The utility model relates to the product cylinder manufacturing technology, especially refers to a kind of unidirectional product cylinder structure of using diaphragm isolation, seal compression chamber.
Background technique
Unidirectional cylinder is a kind of very common and use pneumatic element extremely widely, and it mainly utilizes pressurized air to promote piston, makes piston rod produce motion and drives the mechanical part operation.At present, our common unidirectional product cylinder utilizes that seal ring is isolated, the seal compression chamber more, this type of relatively typical product such as State Intellectual Property Office are called the utility model patent product of " a kind of one-way resetting cylinder " in the patent No. of notice of authorization on the 29th December in 2010 for the ZL201020161001.1 name, it " comprises cylinder barrel; described cylinder barrel one end is provided with bonnet; bonnet is provided with the back bonnet bolt; described back bonnet bolt is provided with bolt nut; be provided with piston in the described cylinder barrel, and described piston connects outside double-screw bolt by the double jaw structure of piston rod.Compared with prior art, it has characteristics such as reasonable in design, simple in structure, easy for installation, that user cost is low." but this product in when work, be embedded at the outer seal ring of piston and ceaselessly rub mutually with inner wall of cylinder, just can be guaranteed the product cylinder proper functioning so must regularly safeguard the replacing seal ring; In addition, because seal ring and inner wall of cylinder have and relatively move,, can't be applied to high pressure, heavily loaded Pneumatic Application again so the withstand voltage properties of this series products is relatively poor.For this reason, it is reliable, non-maintaining and be suitable for the unidirectional product cylinder that high pressure, heavily loaded field use and come out that people expect to invent a kind of ride quality, to overcome need periodic maintenance and narrower defective and the deficiency of application that existing traditional unidirectional product cylinder exists, with the performance and the quality of the unidirectional product cylinder of further lifting.
The model utility content
The technical problems to be solved in the utility model is to overcome need periodic maintenance and narrower defective and the deficiency of application that existing traditional unidirectional product cylinder exists, provide a kind of ride quality reliable, non-maintaining and be suitable for the unidirectional product cylinder that high pressure, heavily loaded field are used to society, with the performance and the quality of the unidirectional product cylinder of further lifting.
The technological scheme that its technical problem that solves the utility model adopts is: the unidirectional cylinder of diaphragm type comprises pot shape cylinder body and peviform cylinder cap, and described cylinder body and described cylinder cap are fixedly connected by a plurality of bolts, and described cylinder cap center is provided with and connects gas port; The edge of described cylinder body and described cylinder cap is embedded with flexible sheet; The end of described cylinder body is provided with guide pin bushing, is provided with piston rod in the described guide pin bushing, and an end of described piston rod is inserted in the cavity volume of described cylinder body and the formation of described diaphragm, and the other end stretches out in outside the described guide pin bushing; Described piston rod is provided with spring seat with the end that described diaphragm faces mutually, is provided with spring between described spring seat and the described inboard wall of cylinder block.
Described guide pin bushing appearance is provided with a pair of set screw nut.
The utility model since use diaphragm with compression chamber with common pressure chamber is isolated and sealing, so can not cause the decline of sealability owing to rubbing during piston rod work, thereby can prolong maintenance period greatly, even accomplish non-maintaining; Because the good seal performance that diaphragm self possesses connects the gas port input air pressure thereby can improve greatly, make this product be applicable to high pressure, heavy-duty applications field again.Compare than existing product, have features simple structure, novel, advantage that Security is good, can be widely used in pneumatic control fields such as boats and ships heavy industry, petrochemical industry, medical equipment, engineering machinery.
Description of drawings
Fig. 1 is the utility model product structure schematic representation.
Embodiment
As shown in Figure 1, the unidirectional cylinder of the utility model diaphragm type comprises pot shape cylinder body 7 and peviform cylinder cap 1, and described cylinder body 7 and described cylinder cap 1 are fixedly connected by a plurality of bolts 5; The edge of described cylinder body 7 and described cylinder cap 1 is embedded with flexible sheet 2 and does to isolate and sealing, and described cylinder cap 1 center is provided with and connects gas port 4; The end of described cylinder body 7 is provided with guide pin bushing 9, is provided with piston rod 10 in the described guide pin bushing 9, and an end of described piston rod 10 is inserted in the cavity volume of described cylinder body 7 and 2 formation of described diaphragm, and the other end stretches out in outside the described guide pin bushing 9; Described piston rod 10 is provided with spring seat 3 with the end that described diaphragm 2 faces mutually, is provided with spring 6 between described spring seat 3 and described cylinder body 7 inwalls; Described guide pin bushing 9 appearances are provided with a pair of set screw nut 8 and are used for installing and fixing of this product and pneumatic system.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.During installation, this product is fixedly installed in the atmospheric control device, simultaneously pressure interface is connected with the gas port 4 that connects of described cylinder cap 1 by set screw nut 8.During work, connecing gas port 4 input air pressures, pressurized air acts on piston rod 10 by diaphragm 2 through spring seat 3, and after overcoming spring 6 active forces, piston rod 10 is stretched out by guide pin bushing 9 starts working.After the release, spring 6 drives piston rod 10 and returns back to reset condition.Because this product is used diaphragm 2 will be isolated at compression chamber between cylinder cap 1 and the diaphragm 2 and the common pressure chamber between cylinder body 7 and diaphragm 2, seal, so when piston rod 10 work, can not be because friction causes the decline of sealability, thereby can prolong maintenance period greatly, even accomplish non-maintaining; Because the good seal performance that diaphragm 2 possesses self connects gas port 4 input air pressures thereby can improve greatly, make this product be applicable to high pressure, heavy-duty applications field again.
