Description
Technical field
The utility model relates to fluidic medium valve fields, more particularly, to a kind of pipe clamp regulating valve.
Background technique
Chemical system pipe clip valve is a kind of usual products, bore mostly in small dimension, while mechanism for opening/closing usually uses list
Screw rod, " single clip rod " form, valve body height is very high, and some single-screw mandrels add connecting rod, and " double fastener rod " form, valve height can be appropriate
It reduces, but all more rubber tubes that can not get rid of are too long (packing element ultimate elongation when preventing from closing), high expensive problem.Some heavy calibers
It stretches excessive when to prevent packing element from closing and lampshade type is used to design, bulky, high expensive, while mounting height is also inclined
It is high.In addition the pipe clip valve of tradition due to the small valve that breathes no more on valve body, therefore generates between valve body and rubber tube certain when closing valve
Vacuum or pressure have certain damage to packing element, while will increase and close valve torque, and another rubber tube rupture is also without feedback, prompting function
Energy.
The Chinese utility model patent " valve core structure of pipe clip valve " of Publication No. CN105972243 discloses a kind of big mouth
The plug-type crank rod-pulling type valve core structure that diameter pipe clip valve uses, though relatively simple for structure, spool the operation is stable, valve height
Very high, installation space is big, and cost just greatly increases if the utility model is using this pattern valve core structure.
Utility model content
The purpose of this utility model is exactly to provide a kind of pipe clamp adjusting to overcome the problems of the above-mentioned prior art
Valve.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pipe clamp regulating valve, including valve body, the rubber tube being arranged between the entrance and exit of valve body two sides and setting
In the valve deck of body top, which further includes the screw mandrel drive mechanism to control rubber tube opening and closing, the rubber
Packing element is through-type structure, and the bellows segment for guaranteeing that rubber tube freely extends is equipped in entrance and exit side.
The screw mandrel drive mechanism includes sequentially connected operation machine, active screw rod, passive screw rod, upper rod axis and lower rod
Axis, the upper rod axis both ends pass through driving nut respectively and connect with active screw rod and passive screw rod, the lower rod axis both ends
Respectively by driving nut to connect with active screw rod and passive screw rod, the operation machine is connect with active screw rod transmission, described
Active screw rod upper end and passive screw rod upper end be sequentially connected.
The active screw rod is identical with passive screw structure, be integrally formed and with opposite thread upper screw rod and
The upper screw rod of lower screw rod, active screw rod is sequentially connected by the upper screw rod of sprocket wheel and chain and passive screw rod.
The operation machine is arranged on valve deck, which is provided with handwheel, and the rod axis is opposite with the middle part of rubber tube to hang down
Straight setting.
It is additionally provided with breather valve on the valve deck, to prevent between valve body and rubber tube with the opening and closing of rubber tube and interior
The variation of portion's volume generates vacuum and pressure.
The valve body lower portion is equipped with the detection ball valve to detect rubber tube rupture.
The detection ball valve is connect with external pressure sensor or warning device.
The operation machine is worm screw machine.
Compared with prior art, the utility model has the advantage that
1, the utility model using sprocket wheel, chain drive and turn round worm gear, worm screw machine operation, can with manually, electrically, behaviour
Make, it is reliable convenient.
2, the utility model had not only had the anti-function that leaks of rubber tube rupture, but also can be by preventing with ripply rubber tube
Vacuum and pressure are generated during normal switch between packing element and valve body, while can realize that packing element ruptures remote alarming function.
3, the utility model can adapt to bigbore pipeline, since the height of the utility model is lower, less than aperture
1.5 times, therefore can adapt to the pipeline of 600 or more bores.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
As shown in Figs 1-4, the utility model provides a kind of pipe clamp regulating valve, including valve body 1, valve deck 2 and setting in inside
Rubber tube 3, screw rod 4, rod axis 5, driving nut 6, sprocket wheel 7, chain 8, and the operation machine 9 of outside, breather valve 10 and detect
Ball valve 11.
Rubber tube 3 is fixed on 1 liang of flange face end of valve body, and intermediate position can open and close under the control of upper and lower two sticks axis 5
Movement, in order to control the height and length of pinch valve, rubber tube 3 uses through-type structure, and both ends increase local glass line shape, protect
Card rubber tube 3 freely extends in off position, does not increase the gravitation of rubber inside.
It is height-limited due to valve body 1, open and close the upper and lower of two screw rods 4 (active screw rod and passive screw rod) of rod axis 5
End uses left and right opposite thread, and by 8 Synchronous Transmissions of link of sprocket wheel 7, guarantees that rod axis 5 is opened and is closed simultaneously up and down, up and down
Rod axis 5 separates, closing action under the action of driving nut 6, particularly due to 4 upper and lower ends silk tooth rotation direction of screw rod just phase
Instead, upper end is left tooth, lower end is right tooth, so two driving nuts 6 can make relative separation under the rotation of screw rod and close up dynamic
Make.
Operation machine 9 is installed on valve deck 2, is connect with a wherein screw rod 4, sprocket wheel 7 set there are two be respectively arranged in actively
The upper end of screw rod and passive screw rod, and linked together Synchronous Transmission by chain 8.
In order to guarantee just in case the rupture generation medium of rubber tube 3 leaks, therefore 1 valve deck 2 of valve body is designed using closed pressure-bearing, simultaneously
Breather valve 10 is added on valve deck 2, prevents rubber tube 3 in opening-closing process, and vacuum or pressure are generated between rubber tube 3 and valve body 1
Power, and influence valve performance.In addition pressure sensor and warning device can be installed additional on detection ball valve 11, realizes that rubber tube 3 is broken
Split remote alarming function.
