Along with the raising of scientific and technological level and change popularizing of production now, in food, beverage, dairy products, pharmacy, brewage, a large amount of the beginning of industry such as beer, chemical industry, oil use valve as produce, control unit in the circulation.Because the specific (special) requirements of food, the various media of field of biological pharmacy, often the turbidity test to valve all have some special requirements, and this just need carry out frequent cleaning to satisfy its requirement to valve.Existing health level valve cleans the general method of cleaning on the throne (CIP) that adopts and cleans, and CIP cleans and promptly do not decompose manufacturing mechanism, and the automatic purging system of available again simple operations method safety almost is introduced into all food, factories such as beverage and pharmacy.This method has and improves throughput, saves the labour force, reduces production costs and increase advantage such as machine part service life, has therefore obtained using widely.
But it is often powerless to the valve opening and closing element of more existing linearly operatings that this CIP cleans, and do not reach the purpose of thorough cleaning.Valve opening and closing element refers generally to can realize valve opening, close, and is used to block, the parts of regulated fluid.When valve closing, sealing surface on open-shut device and the valve body constitutes sealing pair, guarantees that fluid in the valve can not reveal under certain pressure in pipeline yet.The existing valve opening and closing element sealing configuration of doing linearly operating is generally nothing more than following several forms: have plenty of taper open-shut device and circular arc valve seat formation full-metallic sealing pair; Have plenty of coating such as rubber, plastics or be embedded in metal valve and constitute metal and nonmetallic sealing pair with metal seat valve more beyond the Great Wall.Problems such as that but above-mentioned full-metallic sealing pair exists is shockproof, poor sealing performance, above-mentioned metal and though nonmetal sealing pair is shockproof, sealability is better, but when food, pharmacy etc. require than high-cleanness, high, because rubber and plastics are to be coated on fully in the metal valve match, therefore structurally be easy to form and have the not dead angle of easy cleaning, so just can not satisfy the hygienic requirements of health level valve.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of valve of linearly operating of new structure, and there is not the dead angle that can not clean in this valve, is easy to clean.
For realizing technique scheme, the present invention adopts following technological scheme:
A kind of valve opening and closing element comprises valve body, valve plug, valve piston base, and described valve plug is connected with described valve piston base, and described valve plug and described valve body can form and be sealed and matched, and described valve plug can be taken free floating at described valve plug, and described valve plug is nonmetal valve plug.
Preferably, described valve piston base is provided with a circular groove, and described valve plug is fastened in the described circular groove, and the face of being sealed and matched of described valve piston base and valve plug is taper, and the outer circumferential face of described valve plug is provided with fillet.
Preferably, described valve plug is plastics or rubber material.
Technique scheme has following beneficial effect: since nonmetal valve plug can be in valve piston base free floating, therefore when valve carries out on-line cleaning (CIP), nonmetal valve plug can fluctuate under the impulse force of washing solution, washing solution can wash the gap of valve plug and valve piston base, there is not the dead angle in any position of so just guaranteeing valve opening and closing element, also just guaranteed the turbidity test of valve, made valve satisfy other requirement of health level.
