Abstract

The utility model relates to a safety residual liquid removing energy-saver for a liquified petroleum gas cylinder, which is composed of a sealed duct retractable in the axial direction, wherein, the duct is arranged upright in the cavity of the cylinder, the upper end of the duct is in sealed connection with a bore at the lower end of an angle valve of the cylinder, the bottom of the lower end of the duct is provided with a port, and the end surface of the duct is in contact with the inner bottom face of the cylinder. The utility model can cause residual liquid of liquefied petroleum gas deposited in the cylinder to be discharged automatically and enter a burner for combustion; therefore, not only the trouble for people to clean residual liquid is avoided, but also the combustible material in the residual liquid is fully utilized.

Description

Liquefied petroleum ga steel cylinder safety residul liquid-removing energy saving device

The utility model relates to a kind of auxiliary device of liquefied petroleum ga steel cylinder, exactly is liquefied petroleum ga steel cylinder safety residul liquid-removing energy saving device.

At present, the widely used liquefied petroleum ga steel cylinder of people is made of bottle and angle valve, both sealed attachment, the major defect that this liquefied petroleum ga steel cylinder in use exists is, the LPG (liquefied petroleum gas) residual liquid that is deposited on bottle inner bottom part can't be discharged automatically, and people are in order to remove raffinate, and paid processing or cleaning are voluntarily done by the department that have to arrive raffinate in the specialty removing liquefied petroleum ga steel cylinder, preceding a kind of processing method not only wastes time and energy, but also has increased user's economic burden; A kind of processing method in back is easy to generate disaster hidden-trouble, and these two kinds of processing methods all are that raffinate is outwelled in vain simultaneously, and this is not used the material that can burn in the raffinate, thereby wastes energy.

The purpose of this utility model is in using the liquefied petroleum gas (LPG) process raffinate that is deposited on the liquefied petroleum ga steel cylinder inner bottom part to be discharged for people provide a kind of automatically, and the liquefied petroleum ga steel cylinder safety residul liquid-removing energy saving device that it is utilized.

The purpose of this utility model is achieved in that a sealing duct is placed in the liquefied petroleum ga steel cylinder chamber, its upper end connects with the angle valve lower end endoporus fixing seal of this steel cylinder, its lower end head is made several passwaies, this passway makes the sealing duct endoporus be communicated with steel cylinder intracavity, and this lower end surface contacts with the steel cylinder inner bottom surface.

This programme is to utilize the interior gas pressure of steel cylinder to make the raffinate that is deposited on bottle inner bottom part at first enter this conduit through the passway of sealing duct bottom and enter burner to burn.

After the utility model is realized, make the liquefied petroleum ga steel cylinder user save the trouble of cleaning raffinate, combustible substance is fully used.Advantages such as it has economical and practical, saves the energy, and is safe in utilization.

Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.

Fig. 1 is a structural representation of the present utility model.

As seen from the figure, the utility model by crimp contact 1, air chamber body 2, magnet ring 3, body 4, retaining plug 5, O RunddichtringO 6, spring 7, suction nozzle body 8, press stifled 9, filter screen 10, pressure ring 11 to form, it is placed in steel cylinder 13 inner chambers; Be positioned at crimp contact 1 body in a tubular form of upper end, its upper end cylindrical is complementary with angle valve 12 lower end endoporus, and both interference fit are made outer convex ring body on cylindrical in the middle part of it, for axially locating between itself and the angle valve, is shaped on screw thread on its lower end cylindrical; Air chamber body 2 is body in a tubular form, all makes screw thread in its upper and lower end endoporus, in the endoporus of upper end, and fixed installation ring bodies magnet ring 3, it connects with the lower end outside thread of crimp contact 1 by the upper end snail pit; Body 4 is tubular members, and it all makes screw thread on cylindrical of two ends up and down, and it connects with air chamber endosome 2 lower end endoporus by the upper end screw thread; Suction nozzle body 8 is shaped on the two-stage shoulder hole from top to bottom in tubular construction in its body, make four on its lower end surface circumference and go into the recessed rectangular notch of body direction to it, forms the passway; Retaining plug 5 is body in the form of a ring, is shaped on annular groove on its cylindrical; After insert above-mentioned body 4 lower ends, retaining plug 5 is installed, both scyewed joint from suction nozzle body 8 upper end apertures; 0 RunddichtringO 6 is sleeved in the annular groove that keeps off on plug 5 cylindricals, and retaining plug 5 is arranged in the hole, footpath of suction nozzle body 8 bodies; Spring 6 is arranged in suction nozzle 8 bodies footpath endoporus, presses stifled 9 to fix by ring bodies, and the macropore of stifled 9 cylindricals of this pressure and suction nozzle body 8 lower ends is complementary both interference fit; Sheet filter screen 10 is positioned at suction nozzle body 8 lower end macropores, and is fixing by ring bodies pressure ring 11, interference fit between these pressure ring 11 cylindricals and suction nozzle body 8 lower end macropores; Suction nozzle body 8 lower end surfaces contact with steel cylinder 13 inner bottom surfaces.

Except that between retaining plug 5 and the O RunddichtringO 6, between retaining plug 5 and suction nozzle body 8 endoporus and each point of attachment of both ends of the spring, all the other each points of attachment are all installed after being coated with epobond epoxyn on the contact surface, seal with formation in the utility model installation process; After this device assembling, the angle valve bottom surface with the free height of bottom greater than the height of angle valve bottom surface to the steel cylinder inner bottom surface, difference 10-15mm.This difference is that the utility model axial stretching one way is moved distance.

In the part that the utility model uses, crimp contact 1, air chamber body 2 adopt Common Straight Carbon Steel (Q235B) to add by the figure machine and form, and blue the processing sent out on the surface; Body 4, retaining plug 5, press stifled 9, suction nozzle body 8 to adopt aluminium matter (LY12) materials to add by the figure machine and form, surface passivation is handled; Filter screen 10 is selected copper 80 order silk screens, drawing for use; Pressure ring 11 selects for use plastics to make through molding and forming; O RunddichtringO 6 adopts standard piece (material is rubber I-2); The standard piece that spring 7 adopts the carbon spring steel wire material to make.

The purpose that the utility model is installed magnet ring 3 is that liquid gas is magnetized, and it is more abundant to make it burning; The purpose that filter screen is installed is the solid impurity in the filtering liquefied petroleum gas (LPG), helps preventing to stop up air supply system; The purpose that the axial stretching device is set is well to contact with the steel cylinder inner bottom surface for the ease of its bottom surface.

Certainly, this device also can or connect the sealing duct that forms by some pipeline sections with a monolithic construction and replace, and this conduit upper end connects with angle valve lower end endoporus sealing and fixing, and the passway is made in the lower end, and its lower end is contacted with the steel cylinder inner bottom surface.

In the sealing conduit filter screen and magnet ring can be set as required.
