Description
Technical field
The present invention relates to a kind ofly, belong to the switch valve technical field with working medium expansion snap switch valve.
Background technique
Existing switch valve has electronic and pneumatic two kinds of forms usually.
1, electronic acceleration switching valve: < < the electronic acceleration switching valve operation of 800mm, the beginning opening time is in 10ms-800ms scope for Dn if let 20mm.For example: desire to open fast the Dn=200mm valve, aperture is 65% state, is 4Mp at processing medium, and viscosity is at 0.8737X10
-3Under the Pa.S situation, the response time of current domestic and international product all>=30ms.
2, pneumatic acceleration switching valve: the pneumatic valve response time >=500ms under the above-mentioned condition.
3, working medium expansion switch valve of the present invention is if be applied in the above-mentioned example switching response time≤4mms.
4, the whole dependence on import products of acceleration switching valve current, that China's DENG field electric injection system uses, and the quick switch valve of EFI heavy caliber of the large-sized diesel motor of large-scale marine diesel engine or different field are still waiting exploitation.Chemical industry, the quick switch valves of used heavy caliber such as gas separation industry wait Application and Development.
Because the quick switch valve of heavy caliber has hindered the development of different field, this problem is anxious to be solved.
Working medium expansion acceleration switching valve of the present invention progressively begins to use at compressor field, and the quick heavy caliber switch valve of this inventive principle manufacturing will progressively begin to use in different field.
The above-mentioned response time electronic or pneumatic on-off valve is longer, can not the snap switch valve, can't meet the needs of the demand in snap switch valve field.
Summary of the invention
The objective of the invention is for the response time that solves existing switch valve longer, can not the snap switch valve, can't meet the needs of the needs of problems in snap switch valve field, and then provide a kind of with working medium expansion snap switch valve.
The objective of the invention is to realize through following technological scheme:
A kind of with working medium expansion snap switch valve; Comprise: Returnning spring, piston, working medium inlet, sender property outlet, processing medium inlet, processing medium outlet, valve switch plug, piston cavity heater and process pipelines, be provided with reseting cavity 1 and piston cavity in the said piston cavity heater, piston is arranged in the piston cavity; Returnning spring is arranged in the reseting cavity; One end of Returnning spring contacts with an end of piston, and the other end of Returnning spring contacts with the roof of reseting cavity, and the other end of piston and valve switch plug are connected as a single entity; The valve switch plug is arranged in the process pipelines; The process pipelines of valve switch plug one end is the processing medium inlet, and the process pipelines of the valve switch plug the other end is the processing medium outlet, and the two ends of piston cavity are connected with working medium inlet and sender property outlet respectively.
Response time≤the 4ms of the present invention's switch valve under the situation identical with existing technology has realized the snap switch of valve, can meet the needs of the demand in snap switch valve field.
Description of drawings
Fig. 1 is a kind of structural representation with working medium expansion snap switch valve of the present invention.
Embodiment
To combine accompanying drawing that the present invention is done further detailed description below: present embodiment provided detailed mode of execution, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technological scheme of the present invention.
As shown in Figure 1; Related a kind of of present embodiment with working medium expansion snap switch valve; Comprise: Returnning spring 2, piston 3, working medium inlet 5, sender property outlet 6, processing medium inlet 7, processing medium outlet 8, valve switch plug 9, piston cavity heater 10 and process pipelines 11, be provided with reseting cavity 1 and piston cavity 4 in the said piston cavity heater 10, piston 3 is arranged in the piston cavity 4; Returnning spring 2 is arranged in the reseting cavity 1; One end of Returnning spring 2 contacts with an end of piston 3, and the other end of Returnning spring 2 contacts with the roof of reseting cavity 1, and the other end of piston 3 and valve switch plug 9 are connected as a single entity; Valve switch plug 9 is arranged in the process pipelines 11; The process pipelines 11 of valve switch plug 9 one ends is processing medium inlet 7, and the process pipelines 11 of valve switch plug 9 the other ends is connected with working medium inlet 5 and sender property outlet 6 respectively for processing medium outlet 8, the two ends of piston cavity 4.
The cross section of said valve switch plug 9 is for trapezoidal.
Working principle: by working medium inlet 5 working medium is sent into piston cavity 4, close sender property outlet 6 simultaneously, working medium receives the heat energy of piston cavity heater 10 in piston cavity 4; Working medium increases than volume flow rate, promotes piston 3 and rises, and piston 3 is connected as a single entity with valve switch plug 9; Pulling valve switch plug 9 rose when therefore piston 3 rose; Valve opening, medium is got into by processing medium inlet 7, is gone out by processing medium outlet 8.With arts demand, can close working medium inlet 5 at any time, open sender property outlet 6, by Returnning spring 2 effects, piston falls, and valve switch plug 9 is got back to closed position.Processing medium inlet 7, processing medium outlet 8 are closed simultaneously.Close sender property outlet 6 and prepare unlatching next time.
The above; Be merely the preferable embodiment of the present invention; These embodiments all are based on the different implementations under the general idea of the present invention, and protection scope of the present invention is not limited thereto, and any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
