Abstract
The utility model discloses a pneumatic rubber tube valve which comprises a valve body and a tube. A fluid passageway is arranged at the bottom of the valve body, one end of the fluid passageway is an inlet, the other end of the fluid passageway is an outlet, the tube is arranged in the fluid passageway, an air inlet is arranged at the upper end of the valve body, an external pneumatic actuator is connected with the valve body, a clearance and an enclosed air cavity are formed between the valve body and the tube, and a reinforcing cord fabric layer is arranged inside the tube. According to the pneumatic tube valve, the unique rubber tube sleeve with the reinforcing cord fabric layer can withstand high-frequency opening and closing operation, is acid resistant, alkali resistant and chemical medium resistant, and has a quite long service life; the valve can be installed in an omnidirectional mode, a using pipeline does not need to be washed, and once the rubber tube sleeve is broken, the rubber tube can be easily and quickly replaced; and local or remote automation operation control can be achieved as needed.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of Pneumatic rubber tube valve.
Background technique
Rubber pipe valve is a valve head with elastic valve body, and this elastomer valve physical efficiency is pushed away together by a mechanism or process fluid pressure, or is called as " compression ".In most cases, elastomer is that a simple lining is at the complete lining of inside, whole fluid passage and flange.Lining completely cuts off all moving elements and logistics layer, and the parts that do not contact with solid so just can be by more cheap material, for example carbon steel manufacturing.Simultaneously because the rebound elasticity relevant with elastomeric bushing effectively resisted because the wearing and tearing of solid particle by causing lining.According to the material selection of lining, sebific duct can well be used for the medium of those erode metallic surfaces simultaneously.But when carrying out high-frequency keying operation with acid, when the alkali electroless medium passes through, sebific duct damages easily, therefore greatly reduce the working life of rubber pipe valve, in addition, in some hazardous locations, in order to guarantee safety, the use of manually operated valve is limited, need to carry out remote automation control.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is, a kind of Pneumatic rubber tube valve is provided, this rubber pipe valve long service life, widely applicable, install and control convenient.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Pneumatic rubber tube valve, comprise valve body and sebific duct, the bottom of described valve body is provided with the fluid passage, the two ends of described fluid passage are inlet/outlet, and described sebific duct is located in the described fluid passage, it is characterized in that: the upper end of described valve body is provided with suction port and external pneumatic actuator, have the gap between described valve body and the sebific duct and form airtight air cavity, be provided with the enhancing hangings lay in the described sebific duct.
Aforesaid Pneumatic rubber tube valve is characterized in that: the two ends of described sebific duct are provided with the rubber flange.
Aforesaid Pneumatic rubber tube valve is characterized in that: described pneumatic actuator is provided with the switch of control source of the gas.
The utility model has the advantages that:
1. unique rubber sleeve that strengthens cord that contains can stand high-frequency keying operation, and acid-and base-resisting and chemical mediator have very long working life;
2. valve installation is non-directional, uses pipeline to need not to clean, in case rubber sleeve is damaged, changes rapidly simple; 3. can realize on the spot as required or far distance automaticization operation control.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
For further disclosing the technical solution of the utility model, now be described with reference to the accompanying drawings mode of execution of the present utility model: as shown in Figure 1, a kind of Pneumatic rubber tube valve, comprise valve body 1 and sebific duct 2, the bottom of valve body 1 is provided with fluid passage 3, the two ends of fluid passage 3 are inlet/outlet, and sebific duct 2 is located in the fluid passage 3, have the gap and form airtight air cavity 5 between valve body 1 and the sebific duct 2.The upper end of valve body 1 is provided with suction port and external pneumatic actuator 6, and pneumatic actuator 6 is provided with the switch 7 of control source of the gas.Also be provided with enhancing hangings lay 8 in the sebific duct 2, the two ends of sebific duct 2 are provided with rubber flange 4.
Working principle: when control media was not inputted, the cavity 5 between sebific duct 2 and the valve body 1 was communicated with atmosphere, and sebific duct 2 is subjected to hydrodynamic pressure to be in outside tensioning state.Because the enhancing hangings lay 8 that has several angle to arrange in the sebific duct 2 makes sebific duct 2 axially and the mutual balance of radial pressure, so the length of sebific duct 2 and diameter can not change because of hydrodynamic pressure.When control media entered cavity 5 between sebific duct 2 and the valve body 1, sebific duct was out of shape under pressure medium and dams.
More than by description of listed embodiment, basic conception of the present utility model and basic principle have been set forth.But the utility model never is limited to above-mentioned listed mode of execution, and every equivalent variations, improvement and deliberately of inferior quality behavior of change of doing based on the technical solution of the utility model all should belong to protection domain of the present utility model.
Claims (3)
