Abstract

A cutoff valve for a drinking packing container comprises a valve body and a valve handle with a handwheel. Three interconnected pore passages are arranged in the valve body. The valve handle is connected with the valve body with a screw thread, and the opening and closing of the valve are controlled by the swirling in and out of the valve handle. The utility model is characterized in that the conical end socket of the valve handle touches the pyramidal face of the valve base opening of end of the flowing access channel to form airproof. The cross section of the flowing access is smaller then that of the flowing outside channel. No retardation pressure is produced when the liquid flows in the flowing access channel, so the seal assembly at the connecting part on the valve body and the valve handle is saved. The simplification of the structure makes the accident prevention not easy to appear, which is convenient to lower the cost for mass production.

Description

The beverage packaging unit shutoff valve

Affiliated technical field:

The utility model relates to a kind of beverage packaging unit shutoff valve, refers to a kind of simple in structurely especially, and stable performance, cost is lower and suitable quantity-produced drinking container shutoff valve.

Background technology:

At present, known beverage packaging unit has two types with shutoff valve, a kind of is spring plug formula, a kind of spring-loaded cock formula, and their weak points all are that structure is complicated, and used raw MAT'L has plastics, silaatic, metal, so not only cost is higher and easily cause damage.

Summary of the invention:

The purpose of this utility model provides a kind of simple in structure, and steady quality is reliable, the lower and non-damageable drinking container shutoff valve of cost.

Take following technical scheme for overcoming the deficiencies in the prior art the utility model:

A kind of beverage packaging unit ends the shutoff valve of usefulness, valve rod by a shutoff valve main body and a band handwheel is formed, 3 ducts that are interconnected are arranged on the valve body, at the inlet channel end is that the valve seat mouth is being communicated with outlet flow thus and valve rod is installed the duct, in this duct, have with threaded stem and match negative thread in order to the precession valve rod, the termination of valve rod is the garden taper can form sealing with the valve seat recess cone match, and liquid is cut off at this.

Valve seat mouth and valve rod termination form the interstitial fluid outflow and enter outlet flow when valve rod screws out, because of drinking container liquid outflow pressure be the static pressure of liquid in the outlet flow cross section during greater than valve seat mouth cross section liquid enter outlet flow and just do not produce retardance pressure and do not make valve body and valve rod bonded assembly screw thread place can not produce the liquid blowby, so can save poted assemblies herein.

The beneficial effects of the utility model are:

Existing beverage packaging unit stop valve structure and raw-material kind have been simplified, reduced technology difficulty greatly, also reduced productive costs,, made the not only also convenient recovery of steady quality with Shooting Technique along with number of parts reduces the incidence that certainly will also reduce fault.

Description of drawings

Fig. 1 is a known beverage packaging unit spring plug formula stop valve structure decomposing schematic representation.

Fig. 2 is a known beverage packaging unit spring-loaded cock formula stop valve structure decomposing schematic representation.

Fig. 3 is the utility model beverage packaging unit stop valve structure generalized section.

Among the figure: 1 valve body 2, valve rod 3, inlet channel 4, valve seat mouth

5, valve rod mounting hole 6, outlet flow

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment: in Fig. 3 the utility model section of structure, valve body (1) has 3 ducts that interconnect, and inlet channel (3) inner end is to be communicated with valve rod mounting hole (5) above valve seat mouth (4), valve seat mouth are concave cone shpae valve seat mouth.

Its axis and valve seat mouth axis are same axis, the screw thread that matches with valve rod (2) are arranged in order to precession valve rod (2) in the valve rod mounting hole, and valve rod can be made together with handwheel, and the valve rod termination is the garden taper and contacts to finish with valve seat prostomum face and close.

Valve seat mouth (4) is being communicated with outlet flow (6), and the cross section of outlet flow (6) is greater than valve seat mouth (4) cross section, can be in 1-1.5 times of scope, and can smooth and easy fluently discharge when making valve rod open the liquid that flows out from the valve seat mouth to enter outlet flow.

Claims

1, a kind of beverage packaging unit shutoff valve is made up of the valve rod of a valve body and a band handwheel, the inlet channel of valve body is being communicated with outlet flow and valve rod is installed the duct, it is characterized in that: the taper termination, garden of valve rod contacts with the concave cone mouth of inlet channel extreme trace and forms sealing and finish and end, and the inlet channel cross section is less than the outlet flow cross section.

2, beverage packaging unit according to claim 1 is characterized in that with shutoff valve: valve body is connected with a chain for binding criminals line with valve rod.
