Embodiment Construction

[0013] In order to clearly illustrate the solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings.

[0014] see figure 1 , the filling valve includes:

[0015] The cylinder 7 installed in the valve body 5, the piston rod of the cylinder 7 is fixed by the valve core positioning ring 4; on the valve core positioning ring 4, a sealing ring 6 is installed between the piston rod of the cylinder 7 and the valve body 5, and the valve body 5. Install two layers of barbed wire at the discharge port, including the first layer of barbed wire 1 and the second layer of barbed wire 2. The mesh number of the first layer of barbed wire 1 and / or the second layer of barbed wire 2 is 20-30, and the spool 3 In the valve body 5, above the two layers of barbed wire.

[0016] The back-drawing anti-drip filling valve mainly uses the method of lifting the spool 3 upward to close the valve to cut off t...

Abstract

The invention discloses a reverse pumping type anti-drip filling valve; the filling valve comprises a cylinder arranged in a valve body; a piston rod of the cylinder is fixed by a positioning ring of a valve core; the position of the material outlet of the valve body is provided with at least one layer of wire gauze; the valve core is in the valve body and above the wire gauze; on the positioning ring of the valve core, a sealing ring is arranged between the piston rod of the cylinder and the valve body; the amount of the wire gauze is two layers comprising a first layer wire gauze and a second layer wire gauze; the mesh amount of the first layer wire gauze and / or the second layer wire gauze is 20-30. The filling valve has simple structure, and solves the drip returning problem existing in the low-viscosity or high-viscosity fluid filling process reliably; moreover, the time for pumping the vacuum or blowing the residual materials after the filling is finished is not needed, and therefore the filling efficiency is improved.

Description

technical field [0001] The invention relates to a filling valve, in particular to a back-drawing anti-drip filling valve. Background technique [0002] During the liquid filling process, after the filling is completed, there will be "back dripping" at the discharge port of the filling valve (that is, after the filling is completed, there will be 1-2 drops of material dripping at the discharge port of the filling valve. ). [0003] In the filling process of low-viscosity liquids, the "back dripping" problem can be better solved by vacuuming after filling, but the structure of the filling valve is complicated due to the need to add a vacuum tube in the center of the filling valve , the processing and use costs are relatively high, and the effect of controlling "back dripping" is greatly affected by the degree of vacuum. If there is a large fluctuation in vacuum degree, the effect of controlling "back dripping" will be greatly reduced; during the filling process of high-viscos...
