Description
Technical field
This utility model relates to a kind of valve, especially one self with the online tank bottoms diaphragm valve of sterilizing interface.
Background technology
Existing tank bottoms diaphragm valve is the valve that metal valve stem spool separates formation with diaphragm, as it is shown in figure 1, a district with
Tank bottoms radian transition, but b district defines a dead angle point, as in figure 2 it is shown, material flows to c district, valve from b district when valve is opened
Bar 1 is descending utilizes spool 2 to seal the pressure of diaphragm 3, owing to during valve closing, metal spool 2 and metal seat valve 4 are right
The immense pressure that diaphragm produces, when valve is opened, diaphragm is torn and damages by material adhesion, makes beat greatly the service life of diaphragm
Discount；But the most at home and abroad to tank bottoms in some special process in medicine, biological product, chemical industry, food-processing industry
Service life and the reliability requirement of diaphragm valve are the highest, and the reliability of sterilization system on line is even more important, and therefore present structure is tank bottoms
Diaphragm valve is difficult to meet above-mentioned requirements.
Summary of the invention
The purpose of this utility model is to propose a kind of without the dead angle tank bottoms diaphragm valve of band sterilization system on line, employing barrier film spool,
The tank bottoms diaphragm valve of the sterilization system on line of band without dead angle using this diaphragm valve core structure designs disclosure satisfy that present pharmacy and biological product
The most oily etc. industry with online high-temperature sterilization in the technological requirement that frequently switches on.
This utility model is to use following technical scheme to realize: without the dead angle tank bottoms diaphragm valve of band sterilization system on line, including
Valve body, described valve body composition includes handle, copper nut, valve rod, valve gap, valve seat "O"-ring, barrier film spool and valve seat, described every
Film spool is by diaphragm and spool integral structure structure, and barrier film spool is arranged in valve base cavity；Valve seat "O"-ring sets
Meter is between valve gap and barrier film spool, and copper nut is fixed together with handle, and valve rod upper end and handle are fixed and be connected, lower end and every
Film spool is fixing to be connected, and copper nut rotational band ovable valve stem on the external screw thread of valve gap moves up and down, and valve rod drives diaphragm valve simultaneously
Core does switch motion, and described valve body is designed with sterilization system on line interface.
Described sterilization system on line interface, by sampling valve seat, samples barrier film spool, samples valve rod, samples valve seat "O"-ring, sampling
Valve gap, bonnet nut and Sampled Hand Grip form a microdiaphragm valve and constitute.
Valve body feed zone and tank bottoms same arc, barrier film spool is tank bottoms without dead angle after closing valve, opens valve rear feeding district
Material will flow to discharge zone makes material flow out, and sterilization system on line interface accesses pure steam, and pure steam is through body cavity to discharge
Pipeline, sterilizes to body cavity and drainage line before completing discharge.
Described barrier film spool material therefor is Daikin new material PTFE(politef), oil resistant and bending resistance
By force.
This utility model provides the benefit that by using said structure design effectively to solve the most tank bottoms
Dead Core Problems, also solves a drainage line sterilizing difficult problem before discharge simultaneously, meets the most at home and abroad medicine, biological system
In product, chemical industry, food-processing industry, production and processing technology is high to service life and the reliability requirement of tank bottoms diaphragm valve, disappears online
Requirement in terms of the reliability of poison.

Detailed description of the invention
As shown in Figure 4, without the dead angle tank bottoms diaphragm valve of band sterilization system on line, including valve body, described valve body composition includes handle 5,
Copper nut 6, valve rod 7, valve gap 8, valve seat "O"-ring 9, barrier film spool 10 and valve seat 11, described barrier film spool 10 is arranged on valve seat
Intracavity in 11；Valve seat "O"-ring 9 designs between valve gap 8 and barrier film spool 10, and copper nut 6 is fixed together with handle 5, valve
Bar 7 upper end is fixed on handle 5, and the other end is fixed on barrier film spool 10 side, and copper nut 6 rotates on the external screw thread of valve gap 8
Band ovable valve stem 7 moves up and down, and valve rod 7 drives barrier film spool 10 to do switch motion simultaneously, and described valve body is designed with sterilization system on line
Interface.
Feed zone c and tank bottoms same arc as shown in Figure 3, barrier film spool 10 is tank bottoms without dead angle, after opening valve after closing valve
The material of feed zone will flow to discharge zone makes material flow out, and sterilization system on line interface f accesses pure steam, and pure steam passes in valve body
Body cavity and drainage line, to drainage line, are sterilized before completing discharge by chamber e, d.
Sterilization system on line interface of the present utility model, by sampling valve seat 12, samples barrier film spool 13, samples valve rod 14, samples valve
Seat "O"-ring 15, samples valve gap 16, and bonnet nut 17 and Sampled Hand Grip 18 form a microdiaphragm valve and constitute.
It is concrete to the one of technical solutions of the utility model that above-mentioned detailed description of the invention that to be declared is simply combines accompanying drawing
Embodiment, it is impossible to as the foundation of restriction this utility model scope of patent protection, any based on technical solutions of the utility model
For belonging to the protection domain of this utility model patent right through the technical scheme of inventive improvements.
