Abstract
The utility model discloses a refrigerated water supplies bypass that circulates for manufacturing equipment between return water, including cold water supply channel and cold water return water pipeline, the cold water supply channel inserts capsule machine surface cooler, and cold water return water pipeline channel qi moves the three -way valve and connects out from capsule machine surface cooler, and the cold water supply channel passes through the backwater branch pipe way and inserts pneumatic three -way valve, and cold water is in the recurrent state always, and usefulness is promptly opened promptly to cold water, has also avoided blocking the impact of cold water to the main line because of closing the valve simultaneously.
Description
Technical field
The utility model belongs to pharmaceutical equipment technical field, is specifically related to a kind of process equipment chilled water for the bypass that circulates between backwater.
Background technology
Process equipment surface cooler refrigerant used is 7 DEG C of cold water, is supplied by chilled water system pipeline, is divided into supply channel and water return pipeline.Existing control mode is: on inlet pipeline, be provided with a two-way electronic valve, by controlling the break-make of two-way valve thus controlling the break-make of chilled water, and then controls the air themperature by surface cooler.Process equipment with cold water pipeline when closing water inlet electric two-way valve, cold water to pipeline impact large and process equipment cold water for a long time need not, because cold water does not circulate, water temperature raises, can not plug and play.
Utility model content
The utility model provides a kind of process equipment chilled water for the bypass that circulates between backwater, is in recurrent state, cold water plug and play always, it also avoid because valve-off blocks the impact of cold water to main line simultaneously for cold water in backwater main line.
The utility model solves the technical scheme that its technical problem adopts: process equipment chilled water of the present utility model is for the bypass that circulates between backwater, comprise cold water supplying pipe road and cold-water return pipeline, cold water supplying pipe road access seed-coating machine surface cooler, cold-water return pipeline picks out from seed-coating machine surface cooler through Pneumatic three-way valve, and cold water supplying pipe road is by return branch road access triple valve.
Stop valve is installed in the front end on access return branch road, cold water supplying pipe road.
Triple valve can realize different working methods, and when being communicated with seed-coating machine surface cooler, return branch road is not communicated with, and chilled water circuit normally works; When not being communicated with seed-coating machine surface cooler, cold water can only directly enter cold-water return pipeline by return branch road, without process equipment surface cooler.When seed-coating machine surface cooler does not work, but ensure that cold water is in recurrent state, cold water plug and play for backwater main line cold water always, it also avoid because valve-off blocks the impact of cold water to main line simultaneously.
Pneumatic three-way valve is installed, had both achieved the control to backwater two paths, and met requirement of explosion proof again;
The installation site of Pneumatic three-way valve is on cold-water return pipeline, because pressure of return water is relatively low, installs the impact that can alleviate valve like this; Because pressure of supply water is relatively high, valve installation avoids the impact of supplying water to fan coil on backwater;
The practical function of triple valve changes and non-truncated cold water pathway, do not affect, can not impact main line for cold water main pipe road;
When surface cooler does not need cold water, cold water supplying pipe road is directly connected with water return pipeline by triple valve, although cold water is without surface cooler, forms path, can not form immobilising stagnant water, ensure that cold water temperature is in about 7 DEG C always in surface cooler front end.
Accompanying drawing explanation
Fig. 1 is that process equipment chilled water of the present utility model is for the bypass structure schematic diagram that circulates between backwater.
In figure: 1. cold water supplying pipe road; 2. cold-water return pipeline; 3. return branch road; 4. Pneumatic three-way valve; 5. stop valve; 6. seed-coating machine surface cooler.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
See Fig. 1, process equipment chilled water of the present utility model is for the bypass that circulates between backwater, comprise cold water supplying pipe road 1 and cold-water return pipeline 2, seed-coating machine surface cooler 6 is accessed on cold water supplying pipe road 1, cold-water return pipeline 2 picks out from seed-coating machine surface cooler 6 through Pneumatic three-way valve 4, and cold water supplying pipe road 1 is by return branch 3 tunnel access Pneumatic three-way valve 4.
Stop valve 5 is installed in the front end that return branch road 3 is accessed on cold water supplying pipe road 1.
Pneumatic three-way valve 4 can realize different working methods, and when being communicated with seed-coating machine surface cooler 6, return branch road 3 is not communicated with, and chilled water circuit normally works; When not being communicated with seed-coating machine surface cooler 6, cold water can only directly enter cold-water return pipeline 2 by return branch road 3, without process equipment surface cooler.When seed-coating machine surface cooler 6 does not work, also can ensure that cold water is in recurrent state, cold water plug and play for backwater main line cold water always, it also avoid because valve-off blocks the impact of cold water to main line simultaneously.
See Fig. 1, triple valve working method: two path: B → AB or A → AB. can be realized by autocontrol mode
System operating mode: when triple valve is in B → AB state, A → AB. is in off-state, cold water is completely by entering cold-water return pipeline 2 after process equipment surface cooler, and seed-coating machine surface cooler 6 is in running order;
When Pneumatic three-way valve is in A → AB state, B → AB is in off-state, cold water can only directly enter cold-water return pipeline 2 by return branch road 3, without process equipment surface cooler, cold water is in recurrent state for backwater main line cold water always, cold water plug and play, it also avoid because valve-off blocks the impact of cold water to main line simultaneously.
Claims (2)
1. a process equipment chilled water is for the bypass that circulates between backwater, it is characterized in that: comprise cold water supplying pipe road and cold-water return pipeline, cold water supplying pipe road access seed-coating machine surface cooler, cold-water return pipeline picks out from seed-coating machine surface cooler through Pneumatic three-way valve, and cold water supplying pipe road is by return branch road access Pneumatic three-way valve.
2. process equipment chilled water according to claim 1 is for the bypass that circulates between backwater, it is characterized in that: stop valve is installed in the front end on access return branch road, cold water supplying pipe road.
