Description

A kind of steaming pot safety installations

Technical field

The utility model relates to steam pressure container safety protection field, particularly a kind of steaming pot safety installations

Background technique

At present, steam autoclave is widely used in the industries such as food-processing industry, pharmacy, sterilization, chemical industry, article to be processed are put into steam tank body, to tank body, pass into thermal source, utilize high pressure steam to process article, when article that taking-up processes, the residual steam in tank body need to be discharged, make the pressure in tank body identical with ambient pressure, like this guarantee safety.

In prior art, employing is arranged several outstanding iron blocks at lid open end, and the breach of indent is set at tank end, and the iron block that lid end is arranged by rotating cover revolves in the breach of the indent of putting tank end setting, compress iron block, thereby realized the effect of tightening cover door; Yet after described lid and tank body sealing, frequent meeting is due to the pressure transient in tank, or artificial touching, lid there will be rotation phenomenon.Like this, the sealing stability of lid and tank body can not be guaranteed; In addition, sometimes the steam in tank body is also completely not drained, when opening door closure body, and the steam of high temperature be easy to burn operator's skin, steam autoclave is just very dangerous.

Model utility content

The purpose of this utility model is that the locking that provides a kind of safety installations to solve lid takes into account the residue high-temperature steam of discharging tank body, improves the Security of steam autoclave.

For realizing above object, the technical solution adopted in the utility model is: a kind of steaming pot safety installations, the tank mouth place of steaming pot tank body arranges lid, the locking framework that prevents that lid from opening is arbitrarily set between the tank mouth place of described lid and steaming pot tank body, the bleed valve that is communicated with inside, tank chamber is set on steaming pot tank body, and the spool of bleed valve is connected with locking framework synchronous interaction.

There is following technique effect in the utility model: the locking framework arranging between lid and the steaming pot tank body at tank mouth place locks lid, when locking framework is opened, the enabling signal of sending makes the bleed valve synchronous interaction being connected with locking framework open bleed valve, discharge remaining high pressure steam, like this, the security and stability that steaming pot is used is improved.

Embodiment

In order conveniently to understand the utility model, locking mechanism (matching mechanism of lid and tank body) and locking framework (restriction locking mechanism is in the mechanism of locking mated condition) are set forth; Locking mechanism essence refers to: lid open end is arranged several outstanding iron blocks, the breach of indent is set at tank end, the iron block that lid end is arranged by rotating cover revolves in the breach of the indent of putting tank end setting, compresses iron block, thereby has realized the effect of locking lid 20; The similar a kind of insurance institution with safety lock of described locking framework, itself be a kind of to lid 20 safty device with tank body 10 lockings, the Security that improves steam autoclave.

Below in conjunction with Fig. 1 to Fig. 5, this real model utility is described in further detail:

A kind of steaming pot safety installations, the tank mouth place of steaming pot tank body 10 arranges lid 20, the locking framework 40 that prevents that lid 20 from opening is arbitrarily set between the tank mouth place of described lid 20 and steaming pot tank body 10, the bleed valve 30 that is communicated with inside, tank chamber is set on steaming pot tank body 10, the spool 31 of bleed valve 30 is connected with locking framework 40 synchronous interactions, when locking framework 40 open and/or closed, synchronize the bleed valve 30 that connects open and/or closed simultaneously with locking framework 40, so just improved the safety in utilization of steam autoclave.

For realizing further conception of the present utility model, in the spool 31 synchronous interaction problems of locking framework 40 and bleed valve 30, this name of the game is: locking framework 40 makes the open and/or closed that the spool 31 of bleed valve 30 also can be synchronous realize the discharge to tank interior residual gas while making locking framework 40 open and/or closed by mode machinery or electromagnetism.During the concrete enforcement of this problem, there are two kinds of optional schemes:

Scheme one: utilize the mode of electromagnetic type to make the synchronous interaction of spool 31 and locking framework 40; Comprise sensor, sensor gathers the displacement signal of locking framework 40 release actions and this displacement signal is converted to electrical signal transfer to controller, and 30 actions of controller output control signal control bleed valve are communicated with or cut-off venting path.

Scheme two (optimum implementation): adopt mechanical type to make spool 31 and locking framework 40 synchronous interactions; Shown in Fig. 5, the spool 31 of described bleed valve 30 is spherical or cylindrical spool, the mandrel rod 32 being connected with spool 31 one extend to bleed valve 30 valve bodies outside and with locking framework 40 synchronous interactions.

For the model utility conception in implementation two better, described locking framework 40 comprises dead bolt 42 and the snap close 43 cooperatively interacting, and dead bolt 42 is connected with driveshaft 41, and dead bolt 42 is fixedly installed on the tank mouth of steaming pot tank body 10 of lid 20 edge; Described dead bolt 42 is plate-like, and its plate-like periphery comprises arc section 421 and straight section 422 edge contours, and the geometrical center place of described dead bolt 42 is connected with driveshaft 41; Described snap close 43 is tabular, and snap close 43 is positioned at dead bolt 42Yi Ce edge and is provided with concave arc shape contour segment 431; Arc section on described dead bolt 42 421 can be in while rotating when the locking bit that coordinates with concave arc shape contour segment 431 or arc section 421 rotate can be in the two kinds of location statuss of solution lock-bit that misplace with concave arc shape contour segment 431; During locking framework 40 locking, the arc section 421 on dead bolt 42 is in mated condition with the concave arc shape contour segment 431 of snap close, and bleed valve 30 spools 31 are closed; When locking framework 40 is opened, the arc section 421 on dead bolt 42 is in dislocation state with the concave arc shape contour segment 431 of snap close, and bleed valve 30 spools 31 are opened.

For better realizing the conception of locking framework 40, the above concave arc shape contour segment 431 of locking framework 40 is for being less than the arc section of semicircle, and the arc section 421 on dead bolt 42 is for being greater than the arc section of semicircle.

This kind of locking framework 40 is simple in structure, economical and efficient, in described scheme two, model utility conception is the best mode that realizes locking framework 40 and bleed valve 30 synchronous interactions, also have other structure for referencely to select, as long as can discharge the residue high-temperature steam in tank body when can guarantee a kind of secondary locking after lid and tank body locking and needing opening cover, guarantee that the use safety of tank body is all feasible scheme.

As shown in Figure 3 and Figure 4, in fact, when locking framework 40 is assemblied in tank body 10 and lid 20, guarantee that locking framework 40 does not affect closing sealing and/or opening of tank body 10 and lid 20, actual is exactly to lid 20 rotational action on tank body 10 produce to interfere, while manufacturing locking framework 40 according to quantity and the position of concrete size and this kind of safety installations of location arrangements.
