Description

Point valve and tea machine

Technical field

The present invention relates to a kind of point valve, also relate to a kind of tea machine that has used this point valve.

Background technique

The point valve of using in each product of selling on the market now has various; Like the patent No. is ZL200410068343.8; The applying date is the heating cooking stove on August 31st, 2004; The disclosed technological scheme of this patent is: a kind of heating cooking stove comprises: steam generator is used for steam is infeeded in the cooking cavity that is limited to heating cooking stove; The water feed box is used for water is infeeded steam generator; The water service pipe is used for water is infeeded steam generator from the water feed box, and the water feed box removably is connected to the water service pipe; First valve is used for the outlet of control setting on the water feed box, so that water is discharged from the water feed box; Second valve is used for the inlet of control setting on the water service pipe, so that will suck from the water that the water feed box is discharged the water service pipe; Water passage, said water passage are limited between the inlet of outlet and water service pipe of water feed box, are used for water is caused inlet from outlet; Said water passage comprises the insertion portion that extends from the water service pipe; Said water feed box also comprises container, is used to hold the insertion portion of said water service pipe, and wherein said first valve and said second valve interact to open or close said water passage.The deficiency that this patent exists is: opening and closing of said water passage is to interact through first valve and second valve; Be that the interaction of compliant member and compliant member realizes; When two valves to having pushed up for a long time; Possibly cause pressure spring that valve is resetted, also possibly cause valve not open, influence the working life of valve; Disclosed two valves of this patent are not suitable for vertical setting in addition; Because can receive the gravity of liquid when vertically being provided with; The gravity of the big or liquid that mercury column is high of density particularly; This gravity is opening of influence top valve directly, and the spring of below valve can not reset the situation that appearance can't seal fully because of receiving excessive compression.

So be badly in need of on the market that a kind of using effect is good, the life-span is long, do not receive point valve that modes of emplacement influences and the tea machine that has used this point valve.

Summary of the invention
