Description
Technical field
The present invention relates to fluidic medium valve fields, more particularly, to a kind of pipe clamp regulating valve.
Background technology
Chemical system pipe clip valve is a kind of usual products, bore mostly in small dimension, while mechanism for opening/closing usually use it is single
Lead screw, " 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 break away from are long (packing element ultimate elongation when preventing from closing), high expensive problem.Some heavy calibers
Stretched when to prevent packing element from closing it is excessive use lampshade type 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 is generated when closing valve between valve body and rubber tube certain
Vacuum or pressure have certain damage to packing element, while can increase and close valve torque, and another rubber tube rupture is also without feedback, prompting work(
Energy.
The Chinese invention patent " valve core structure of pipe clip valve " of Publication No. CN105972243 discloses a kind of large-diameter pipe
The plug-type crank rod-pulling type valve core structure that valve uses is pressed from both sides, though relatively simple for structure, spool the operation is stable, valve height is very
Height, installation space is big, and cost just greatly increases if the present invention is using this pattern valve core structure.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of pipe clamp regulating valves.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of pipe clamp regulating valve, including valve body, the rubber tube that is arranged between the entrance and exit of valve body both sides and setting
In the valve deck of body top, which further includes controlling the screw mandrel drive mechanism of rubber tube keying, the rubber
Packing element is through-type structure, and the bellows segment for ensureing that rubber tube freely extends is equipped in entrance and exit side.
The screw mandrel drive mechanism includes sequentially connected operation machine, active lead screw, passive lead screw, upper rod axis and lower rod
Axis, the upper rod axis both ends are respectively by driving nut to be connect with active lead screw and passive lead screw, the lower rod axis both ends
Respectively by driving nut to be connect with active lead screw and passive lead screw, the operation machine is connect with active screw rod transmission, described
Active lead screw upper end and passive lead screw upper end be sequentially connected.
The active lead screw is identical with passive screw structure, be integrally formed and with opposite thread upper screw rod and
The upper screw rod of lower lead screw, active lead screw is sequentially connected by the upper screw rod of sprocket wheel and chain and passive lead screw.
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 keying between valve body and rubber tube with rubber tube and interior
The variation of portion's volume generates vacuum and pressure.
The valve body lower portion is equipped with to detect the detection ball valve of 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 present invention has the following advantages：
1, the present invention using sprocket wheel, chain drive and turn round worm gear, worm screw machine operation, can use manually, electrically, operation,
It is reliable convenient.
2, the present invention had not only had the anti-function that leaks of rubber tube rupture, but also can be by being prevented normally with ripply rubber tube
Vacuum and pressure are generated in switching process between packing element and valve body, while can realize that packing element ruptures remote alarming function.
3, the present invention can adapt to bigbore pipeline, since the height of the present invention is relatively low, be less than 1.5 times of aperture, because
This can adapt to the pipeline of 600 or more bores.

Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in Figs 1-4, the present invention provides a kind of pipe clamp regulating valve, including valve body 1, valve deck 2 and is arranged in internal rubber
Packing element 3, lead screw 4, rod axis 5, driving nut 6, sprocket wheel 7, chain 8, and the operation machine 9 of outside, breather valve 10 and detection 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
Action, in order to control the height and length of pinch valve, rubber tube 3 uses through-type structure, both ends to 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 lead screws 4 (active lead screw and passive lead screw) of rod axis 5
End uses left and right opposite thread, and links 8 Synchronous Transmissions by sprocket wheel 7, ensures that rod axis 5 is opened and is closed simultaneously up and down, up and down
Rod axis 5 detaches, closing action under the action of driving nut 6, particularly due to 4 upper and lower ends silk tooth rotation direction of lead screw 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 lead screw and close up dynamic
Make.
Operation machine 9 is installed on valve deck 2, is connect with a wherein lead screw 4, sprocket wheel 7 set there are two be respectively arranged in actively
The upper end of lead screw and passive lead screw, and linked together Synchronous Transmission by chain 8.
In order to ensure 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.
