Abstract
The invention discloses a reciprocating valve rod steam sterilization device. The device comprises a valve body, a valve seat and a cylinder bracket, wherein the valve seat is arranged at the bottom end of the valve body; the other end of the valve body is fixedly connected with the cylinder bracket; the top end of the valve seat is provided with a valve rod; the other end of the valve rod is connected with the cylinder bracket; and a seal ring is sleeved on the valve rod, is in close fit with the inner wall of the valve body and divides an inner cavity of the valve body into an upper cavity and a lower cavity. The device is characterized in that: the valve body is provided with a first air inlet and a first air outlet; the valve rod is provided with a second air inlet and a second air outlet which are respectively positioned in the upper cavity and the lower cavity. Therefore, the reciprocating valve rod steam sterilization device has complete functions and particularly can sterilize the valve rod, the valve seat and the inner wall of the valve body.
Description
Technical field
The present invention relates to a kind of valve rod bactericidal unit, relate in particular to a kind of reciprocating type valve rod steam sterilization device.
Background technique
At present, the reciprocating type valve rod of health level generally is applicable to the liquid flow valve of aseptic requirement, and the Chinese patent notice of authorization number is CN2675979Y; Notice of authorization day is that the utility model patent on February 2nd, 2005 discloses the aseptic valve of a kind of highi degree of accuracy, comprises support, and actuating motor is rack-mount; Be provided with valve body in the support, valve body bottom is provided with diaphragm, and manages a side and be provided with opening being positioned at material on the bracket; Described opening is provided with diaphragm, and described diaphragm is connected with valve rod one end, and the other end of described valve rod contacts with an end of high-precision screw; Described high-precision screw is provided with guide rod, and the outer end of said guide rod is provided with position transducer.The aseptic valve of this kind highi degree of accuracy is mainly used in aseptic pipeline to realize the constant and reasonable distribution to fluid flow; For the sterility of guaranteeing system needs regularly system to be carried out sterilizing treatment; Usually through under certain pressure, realizing sterilization to aseptic pipeline with circulating hot water; And aseptic valve is a seal owing to it, thereby can't carry out sterilization treatment to valve rod and valve seat, and therefore aseptic valve has brought hidden danger to the sterility of whole system.
Summary of the invention
It is more complete that technical problem to be solved by this invention provides a kind of function, especially can carry out the reciprocating type valve rod steam sterilization device of sterilization treatment to valve rod and valve seat and valve interior wall.
For realizing above purpose; The technological scheme that the present invention adopted is: a kind of reciprocating type valve rod steam sterilization device, comprise valve body, valve seat and cylinder support, and said valve seat is arranged on the bottom of valve body; The other end of valve body is fixedly connected with the cylinder support; The top of said valve seat is provided with valve rod, and the other end of this valve rod is connected with the cylinder support, is arranged with seal ring on the said valve rod; Sealing circle and valve interior wall closely cooperate and said body cavity are divided into upper cavity and lower chamber; It is characterized in that: said valve body is provided with first suction port and first air outlet, and said valve rod is provided with second suction port and second air outlet, and this second suction port and second air outlet lay respectively in upper cavity and the lower chamber.
Said first suction port circumferentially becomes the angle setting with said first air outlet, and said first suction port and said first air outlet are positioned at different height.
The cross section of said first suction port and first air outlet is circular.
Compared with prior art, beneficial effect of the present invention is:
1. because reciprocating type valve rod steam sterilization device of the present invention is relatively set with first suction port and first air outlet on valve body.Valve rod is provided with second suction port and second air outlet; Therefore can water vapour be fed the upper cavity of valve body from first suction port; Water vapour in the valve body upper cavity second suction port from the valve rod again gets into, and finally second air outlet from the valve rod goes out, and this moment, water vapour just was full of the whole valve body cavity; Thereby valve rod, valve seat and valve interior wall are carried out sterilization treatment; Therefore water vapour finally can be external from the first air outlet expulsion valve on the valve body, and reciprocating type valve rod steam sterilization apparatus function of the present invention is more complete, especially can carry out sterilization treatment to valve rod and valve seat and valve interior wall.
Description of drawings
Fig. 1 is the structural representation of disclosed reciprocating type valve rod steam sterilization device.
Among the figure: valve body 10, valve seat 11, cylinder support 12, the first suction port 13a, the first air outlet 13b, the second suction port 14a, the second air outlet 14b, valve rod 15, seal ring 16.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is explained further details:
As shown in Figure 1, a kind of reciprocating type valve rod bactericidal unit comprises valve body 10, valve seat 11 gentle jar supports 12; Valve seat 11 is arranged on the bottom of valve body 10; The other end of valve body 10 is fixedly connected with cylinder support 12, and the top of valve seat 11 is provided with valve rod 15, and the other end of this valve rod 15 is connected with cylinder support 12; Be socketed with seal ring 16 on the valve rod 15, seal ring 16 is divided into upper cavity and lower chamber with the inner chamber of valve body 10.
Feed water vapour in the upper cavity of valve body 10 from the first suction port 13a in the practical operation; Water vapour in the valve body upper cavity second suction port 14a from the valve rod 15 again gets into; Finally the second air outlet 14b from the valve rod goes out; This moment, water vapour just was full of the whole valve body inner chamber, thereby valve rod 15, valve seat 11 and valve interior wall are carried out sterilization treatment, and water vapour finally can be discharged outside the valve body 10 by the first air outlet 13b from valve body 10; Therefore reciprocating type valve rod steam sterilization apparatus function of the present invention is more complete, especially can carry out sterilization treatment with valve interior wall to valve rod 10 and valve seat 11.
Those skilled in the art will recognize that; Above-mentioned embodiment is exemplary; Be in order better to make those skilled in the art can understand this patent; Can not be interpreted as it is the restriction that this patent is comprised scope, so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
