Abstract
Provided is a constant voltage control weighted valve. The constant voltage control weighted valve comprises a valve cavity (3), a valve deck (5), an air inlet pipe (6) and an air outlet pipe (7), wherein the air inlet pipe (6) and the air outlet pipe (7) are communicated with the valve cavity (3), a counter weight (1) is arranged in the valve cavity (3), a seal ring (4) is arranged at the bottom of the counter weight (1), and a balance weight lever (2) is arranged, and is connected with a screw hole formed at the bottom of the counter weight (1) in a matching mode. The constant voltage control weighted valve has the advantages of being in purely mechanical principle, and being simple in structure, reliable in performance, convenient to operate and maintain, low in cost, high in use reliability, and convenient to maintain, capable of achieving change of control pressure range of a weighted valve by changing balance weight quality, and simple and easy to operate.
Description
Technical field
The utility model relates to a kind of weighted valve technical field of structures of constant container inner pressure.
Technical background
Existing automatically control gas in container pressure, the regulative mode that adopts is generally:
Detected pressures → signal feed back → judgement output → carry out and regulate, this kind mode cost is higher, and regular maintenance is comparatively difficult; The detection facility volume is usually larger, and separating component is more, and structure is also complicated.
The model utility content
The purpose of this utility model is to adopt a kind of device that plays the control container inner pressure by the spool own wt.This device is made, user cost is lower; Operational safety is high, and it is comparatively convenient to safeguard; Can by changing weight mass, reach change weighted valve pilot pressure scope, simple easy operating.
The purpose of this utility model is achieved by the following technical solution.
A kind of constant voltage control weighted valve, the utility model is characterised in that: the valve gap, the suction tude that is communicated with valve pocket and the steam outlet pipe that comprise valve pocket, sealing valve pocket; Weight is arranged in the valve pocket, and in the bottom of weight seal ring is set, and can make things convenient for to split out at any time replacing; Be provided with the screw of offering counterweight bar and weight bottom and cooperate connections, the counterweight bar can be separated with weight, being convenient to unscrew increases between counterweight bar and weight after separating or gets except balancing weight, and change weight weight reaches and controls different constant voltages.
The weighted valve valve gap can be dismantled by with the bolton sealing, is convenient to put into or take out weight.
For realizing above-mentioned performance requirement, the air inlet pipeline of this weighted valve design links to each other with controlled container made, forms a regulating and controlling container inner pressure system, and is easy for installation; Own wt by weight in the valve makes seal ring reliably contact with suction tude crossing end face, reaches sealing, blocks the effect that gas in container effluxes.When gas in container pressure adds the summation of counterweight bar quality greater than weight, weight will be lifted by gas push, and seal ring and suction tude crossing end face will form the certain interval space, and at this moment gas in container will be flowed through herein, enter the weight valve pocket, efflux through outlet pipe.When gas in container effluxes, when pressure is brought down below weight and adds the summation of counterweight bar quality, by the own wt of weight seal ring will reliably be contacted with suction tude crossing end face, reach sealing, block the effect that gas in container effluxes; Can change the downward active force of weight by increasing at the counterweight bar or reducing balance weight, the corresponding increase of the resistance that gas in container is effluxed or minimizing realize pressure controlled simple operations; Weighted valve is designed with valve gap, seals with bolton.Dismantling valve gap can check, clean weighted valve inside, safeguards weight, changes seal ring.Change counterweight.
The beneficial effects of the utility model are, the constant voltage weighted valve is pure Der Grundsatz der Maschinen, simple in structure, reliable performance, convenient operating maintenance.Cost is lower; Operational safety is high, and it is comparatively convenient to safeguard; Can by changing weight mass, reach change weighted valve pilot pressure scope, simple easy operating.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, a kind of constant voltage control weighted valve, the utility model is characterised in that: the valve gap 5, the suction tude 6 that is communicated with valve pocket 3 and the steam outlet pipe 7 that comprise valve pocket 3, sealing valve pocket; Weight 1 is arranged in the valve pocket 3, and in the bottom of weight 1 seal ring 4 is set, and can make things convenient for to split out at any time replacing; Be provided with counterweight bar 2 and cooperate connection with the screw that weight 1 bottom is offered, counterweight bar 2 can be separated with weight 1, being convenient to unscrew increases between counterweight bar and weight after separating or gets except balancing weight, changes weight weight, reaches the different constant voltages of control.
Weighted valve valve gap 5 can be dismantled by with the bolton sealing, is convenient to put into or take out weight.After can also dismantling the valve inner piece is cleaned, safeguards.
