Description

A kind of packing jar with seal

The utility model relates to the packing jar, and particularly a kind of packing jar with seal can be used for refrigerant or it changes the packing of chemicals.

Commercially available refrigerant all is 1000 kilograms at present, 400 kilograms, 40 kilograms big packing, the valve of this packing tank top as shown in Figure 1, by valve body 1 ' and valve rod 2 ' form, induction opening 1 '-1 that valve body 1 ' have communicates with tank interior and air gate 1 '-2 of vertical connection with it, valve rod 2 ' upward the end by induction opening 1 '-1 has screw thread, and its top is connected with handle 2 '-1, this structure by valve rod 2 ' move up and down and block or unclamp admission piece on the tank body, thereby reach the purpose of sealing or release refrigerant, but this constructional delails is more, the processing technology complexity, the corresponding raising of cost, and this structure causes the leakage of refrigerant easily.

The purpose of this utility model provides a kind of inner wrapping, disposable use, leak tightness is strong, cost is low, easy to use, portative packing jar with seal.

The purpose of this utility model can realize by following technical solution: the packing jar with seal, contain tank body, its constructional feature is that the opening part of tank body is the jar neck with crimping, the fixed one jar of cap of jar neck back seal, the cross section of jar cap is the W shape of distortion, its central authorities are the threaded circle ring columns of an outer wall belt, and the top of circle ring column is sealing of plane, and jar neck is provided with spring washer with the contact position of jar cap.

That the utility model compared with prior art has is light and handy, portable, easy to use, good airproof performance, advantage and good effect that cost is low.

Below by embodiment and contrast accompanying drawing the utility model is described in detail:

Fig. 1 is the cutaway view of the utility model background technology.

Fig. 2 is the semisectional view of the utility model embodiment.

Fig. 3 is the full sectional view of jar cap among Fig. 2.

As Fig. 2, shown in Figure 3, tank body 1 can adopt resistant material, being pressed into wall thickness as metallic material is 0.5 millimeter circular cylindrical cavity, this routine tank body 1 can divide two parts to make, and its underpart is can body 1-1, is straight-tube shape, the recessed gesture 1-5 of a truncated cone-shaped can be pressed in the bottom, the upper end sealing close-fitting unification shape of can body 1-1 is the jar shoulder 1-2 of inverted bowl-type, and a circle groove 1-4 is arranged at the bottom of jar shoulder, and the top of jar shoulder 1-2 is the jar neck 1-3 with crimping 1-3-1.Jar cap 2 can be used the aluminium press forming, and its cross section is the W shape of distortion, and central authorities are the threaded circle ring column 2-1 of an outer wall belt, and the top of circle ring column is the 2-1-1 that seals on a plane, and the outer rim 2-2 of jar cap 2 is the U-shaped flange, and flange is built-in with rubber cradle 3.Tank body 1 with jar cooperating of cap 2 must use specialized equipment, earlier tank interior is vacuumized, inject tank body after again refrigerant being cooled to liquid, and once 2 sealings of jar cap be cemented on jar neck 1-3.

When the utility model uses, screwed circle ring column 2-1 on the jar cap 2 of the nut that fills the material valve on the chilling unit and this packing jar is connected, tighten with special tool, sealing 2-1-1 and filling the nut driving fit of expecting valve on jar cap 2, clockwise direction rotates the valve rod that fills on the material valve, make the needle penetration that penetrates on the valve rod seal 2-1-1, and then the left-hand revolution valve rod, refrigerant discharged.
