Abstract

The utility model discloses an automatic pressure balancing valve which comprises a three-way pipe 9. The utility model is characterized in that the upper end of the three-way pipe 9 is provided with an air discharge cylinder 10. the valve seat in the air discharge cylinder 10 is provided with a valve plate 6 whose position is limited by a spring 3, an adjusting spiral 2, a screw 8 and a baffle 1. The lower end of the three-way pipe 9 is provided with an air inlet cylinder 4. The valve seat in the air inlet cylinder 4 is provided with the valve plate 6 whose position is limited by the spring 3, the adjusting spiral 2, the screw 8 and the baffle 1. The utility model has the advantages that the volatilization of saturated vapor is simultaneously and effectively limited when the purpose that the material can go in and out from a container is guaranteed.

Description

A kind of automatically equalizing voltage valve

The utility model relates to chemical pipeline, particularly the pressure equalizing valve that uses in the pressure-equalizing passageway of pressure vessels for the chemical industry.

The pressure equalizing of pressure vessels for the chemical industry in the prior art in the manufacturing process of reinforced, blowing mainly by unlatching be located at the higher position of container valve, open devices such as manhole or hand hole and finish.General all can not finish pressure equalizing automatically.Especially for some volatile materials and since pressure equalizing be opening towards atmosphere, the saturated vapor of material can freely evaporate in the atmosphere, has both wasted the energy, has polluted environment again.Especially inflammable and explosive and rare material or the solvent, more increased dangerous and the waste factor concerning some.

The purpose of this utility model is the deficiency that exists in the above-mentioned prior art in order to overcome, and designs a kind of automatically equalizing voltage valve.

The purpose of this utility model realizes according to structure described below.This automatically equalizing voltage valve comprises a three-way pipe 9, an exhaust pipe 10 is arranged in the upper end of three-way pipe 9, have one on the valve seat in this exhaust pipe 10 by the spacing valve block 6 of spring 3 and adjusting color screw 2, screw 8 and baffle plate 1, an air induction mast 4 is arranged in the lower end of three-way pipe 9, have one on the valve seat in this air induction mast 4 by the spacing valve block 6 of spring 3 and adjusting color screw 2, screw 8 and baffle plate 1.Above-described structure has promptly realized the purpose of this utility model.

The pressure equalizing that the utility model has the advantages that system is finished automatically, when guaranteeing that material can pass in and out container, can limit the effusion volatilization of material saturated vapor effectively.After serial connection reclaiming system on the exhaust pipe 10, again can be with the vapor recovery of overflowing in the fill process.

The following drawings explanation, accompanying drawing 1 is a structure sectional view of the present utility model, accompanying drawing 2 be A among Fig. 1 to view, accompanying drawing 3 is the B-B views among Fig. 1, accompanying drawing 4 is that C among Fig. 1 is to view.Each sequence number in the accompanying drawings is: 1, plate washer, 2, adjusting color screw, 3, spring, 4, air induction mast, 5, sealing gasket, 6, valve block, 7, pad, 8, screw, 9, three-way pipe, 10, exhaust pipe.

Below in conjunction with the embodiment in the accompanying drawing, describe structure of the present utility model and use in detail.With reference to accompanying drawing, in use three-way pipe 9 is rotatably connected on the balance pipe of container the balance pipe horizontal arrangement of should trying one's best.Make the line of centres of two interfaces up and down of three-way pipe 9 vertical or vertical substantially then with the balance pipe of level.Exhaust pipe 10 up, air induction mast is in the bottom.Have one on the valve seat in the exhaust pipe 10 above three-way pipe 9 by the spacing valve block 6 of spring 3 and adjusting color screw 2, screw 8 and baffle plate 1.Have one on the valve seat in the air induction mast 4 of the lower end of three-way pipe 9 by the spacing valve block 6 of spring 3 and adjusting color screw 2, screw 8 and baffle plate 1.Two valve blocks 6 an and sealing gasket 5 is arranged between the valve seat separately up and down are to guarantee the reliability of sealing.When injecting material in container, pressure in the container increases gradually, after the preset power of power on the valve block 6 in this pressure acts on exhaust pipe 10 greater than adjusting color screw and spring, then the valve block 6 of exhaust pipe 10 is opened, release pressure is when the pressure balance of pressure in the container and atmosphere, then under the effect of the restoring force of spring, valve block 6 resets, and closes exhaust pipe, and a circulation of automatically equalizing voltage is finished.For volatile or have inflammable and explosive and corrosive material, can connect a recovery channel in the upper end of exhaust pipe 10, steam or gas with overflowing import in the reclaiming system, recycle, and have also reduced simultaneously to pollute and dangerous.When discharging in container, the pressure in the container reduces gradually, and after inside and outside differential pressure reached the preset power of adjusting color screw on the valve block 6 that is enough to overcome air induction mast 4 in and spring, air induction mast 4 interior valve blocks 6 were opened the internal tank that atmosphere enters.Pressure in the container gos up, and makes discharging proceed to finish until discharging.In addition, when discharging, if special needs are arranged, also can, connect a pipeline in the bottom of air induction mast 4, import required steam or other gas.For different materials, can be according to the character of itself and the pulling force of adjustment springs such as saturation vapor pressure and usage requirement, to satisfy different needs.
