Description
Technical field
The utility model belongs to conveyance conduit technical field, relates to a kind of valve, particularly a kind of novel pneumatic pipe clip valve.
Background technique
In traditional industry and food industry, often have the liquid such as some particles, powder, mucilage to carry via pipeline at present, now pneumatic tubing clip valve is exactly optimal selection.Pneumatic tubing clip valve on the market comprises valve body, rubber pipe, upper lower flange, and valve body is provided with suction port, as shown in Figure 1, 2, rubber pipe, originally as rubber product, has certain elasticity, in the time pouring pressurized air in valve body, gas pressure inwardly tightens up rubber pipe, realizes the closing motion of valve; After pressurized air discharges, rubber pipe is because self elasticity restores to the original state, thereby makes valve open; Because existing product is to use gland nut that rubber pipe is fixedly mounted in valve body, so while closing due to compressed air pressure reason, may make rubber pipe follow valve body junction to have gas leak phenomenon, cause valve body cavity pressure deficiency, can not realize the closing function of valve, thereby be difficult to reach the usage requirement of this valve.The patent No. is to disclose a kind of pneumatic tubing clip valve in 200820044904.4 patent document, the boss of upper and lower flange and pipe clamp rubber pipe surface of contact are the conical surface, thereby be conducive to rubber pipe to be pressed on the upper and lower port of valve body, in addition, the upper and lower port of valve body is provided with teeth, effectively prevent that rubber pipe from departing from valve body in the time of throttle down, reaches better using effect.But, withstand voltage properties to rubber pipe used and Young's modulus are had relatively high expectations herein, in the closing process of valve, rubber pipe is from being stretched and inwardly tightening up under gas pressure effect, in the opening process of valve, rubber pipe restores to the original state under self flexible effect, the stretching of repeatability causes the fatigue resistance of rubber pipe to reduce, Young's modulus reduces, so working life is shorter, and rubber pipe inevitably can be worn with the part of valve body and upper and lower flange combination, phenomenon easily leaks air.
Summary of the invention
The utility model, in order to overcome the defect of prior art, has designed a kind of novel pneumatic pipe clip valve, and simple in structure, easy for installation, good airproof performance have extended working life of rubber pipe, can be widely applied in fluid food industry.
The concrete technological scheme that the utility model adopts is: a kind of novel pneumatic pipe clip valve, comprise valve body, upper blind flange, lower sealing flange, rubber pipe, valve body is provided with suction port, rubber pipe is arranged in valve body, key is: described rubber pipe is by upper fixing rubber pipe, lower fixing rubber pipe and undulatory compressing rubber pipe composition, upper fixing rubber pipe, lower fixing rubber pipe and compressing rubber pipe are integral type structure or segmental structure, upper fixing rubber pipe is between valve body upper end-hole and upper blind flange, upper blind flange and valve body upper end-hole are locked by upper locking bolt seal, lower fixing rubber pipe is between valve body lower end mouth and lower sealing flange, lower sealing flange and valve body lower end mouth are by lower lock bolt sealing locking, the upper end of compressing rubber pipe is fixedly connected with the lower end of upper fixing rubber pipe, the lower end of compressing rubber pipe is fixedly connected with the upper end of lower fixing rubber pipe.
The beneficial effects of the utility model are: rubber pipe is by upper fixing rubber pipe, lower fixing rubber pipe and undulatory compressing rubber pipe three part compositions, in the closing process of valve, not that compressing rubber pipe itself is stretched, but the constriction of compressing rubber pipe is trailed, so required gas pressure is less, withstand voltage properties and Young's modulus to compressing rubber pipe used are less demanding, extend the working life of compressing rubber pipe, also the length that makes fixing rubber pipe and lower fixing rubber pipe be stretched very little simultaneously, so greatly alleviated the degree that upper fixing rubber pipe and lower fixing rubber pipe are worn, the phenomenon of avoiding leaking air, extended the working life of upper fixing rubber pipe and lower fixing rubber pipe simultaneously.Upper fixing rubber pipe, lower fixing rubber pipe and compressing rubber pipe can be that integral structure can be also segmental structure, both comparatively speaking, it is more convenient when the rubber pipe of integral structure is installed, but more complicated while production, the rubber pipe of segmental structure is simple while production, but more complicated while installation, cuts both ways.
Food stage silica gel layer can ensure the health of food effectively.Between the inside and outside wall of compressing rubber pipe, be provided with stretchy nylon rope, can increase the pliability of compressing rubber pipe.On the inwall of valve body upper end-hole and lower end mouth, be all provided with teeth type anti-skid structure, can increase between upper fixing rubber pipe and valve body upper end-hole, area of contact between lower fixing rubber pipe and valve body lower end mouth, effectively prevent that fixing rubber pipe and lower fixing rubber pipe from departing from valve body in valve closing process, can realize the closing function of valve better.The surface of contact of upper blind flange and upper fixing rubber pipe is the conical surface, the surface of contact of lower sealing flange and lower fixing rubber pipe is also the conical surface, valve body upper end-hole place is provided with the conical surface consistent with upper blind flange gradient, valve body lower end mouth place is provided with the conical surface consistent with lower sealing flange gradient, be conducive to so upper fixing rubber pipe and lower fixing rubber pipe to be pressed abd fixed in valve body, improved sealing and the reliability of pneumatic tubing clip valve.Means of fixation between compressing rubber pipe and upper fixing rubber pipe, between compressing rubber pipe and lower fixing rubber pipe is all that totally enclosed type sealing bonds together, can prevent gas leakage, making has enough pressure in the chamber of valve body, realizes the closing function of valve faster and betterly.Suction port place is provided with solenoid valve, is connected with control system, can realize remote monitoring, saves human and material resources, increases work efficiency.
