Abstract
The utility model discloses a control piston for a combined valve of an oil-water separator. The control piston comprises a piston body in which a piston rod is arranged. A ring platform is arranged on the outer wall of the piston body. A membrane is arranged on the top of the ring platform. A membrane pressure plate for tightly pressing the membrane is also sleeved outside the piston body. The control piston also comprises a valve cover which is covered outside the upper part of the piston body and pressed on the membrane pressure plate. An upper spring seat is fixed on the inner wall of the top of the valve cover. A regulating valve is connected to the rod end of the top of the piston rod. A lower spring seat is fixed on the top of the regulating valve. A spring is connected between the upper and lower spring seats. The control piston is simple in structure and easy to implement, the working stability of the control piston for the combined valve of the oil-water separator can be effectively improved, and the service life of the control piston is also prolonged.
Description
Technical field
The utility model relates to the oil and water seperator field, is specially a kind of control piston of oil and water seperator combination brake switch and proporting.
Background technique
Oil and water seperator is the instrument that oily and water separation are come, and principle mainly is the density difference according to water and fuel oil, utilizes sedimentation theory to remove the separator of impurity and moisture content.Oil and water seperator inside is equipped with combination brake switch and proporting; In combination brake switch and proporting, be provided with control piston; Existing technology oil and water seperator combination brake switch and proporting control piston is owing to be operated in the profit mixed environment; Pistons work is prone to problem of unstable, and critical component is prone to be corroded in the piston, causes piston to reduce working life.
The model utility content
The utility model purpose provides a kind of control piston of oil and water seperator combination brake switch and proporting, to solve oil and water seperator combination brake switch and proporting control piston job insecurity, critical component low problem in working life.
In order to achieve the above object, the technological scheme that the utility model adopted is:
The control piston of oil and water seperator combination brake switch and proporting; Include piston body, it is characterized in that: be slidingly fitted with piston rod in the said piston body, the piston body outer wall is provided with annular table; The annular table top is provided with the diaphragm that is enclosed within on the piston body; Said piston body also is with outward said diaphragm is pressed on the diaphragm pressing plate on the annular table, also includes to cover on outside the piston body top and be pressed in the valve cover on the diaphragm pressing plate, and said valve cover top inner wall is fixed with the spring seat of honour; Said piston rod part rod end passes piston body and stretches in the valve cover; And the piston rod part rod end is connected with regulating valve, and said regulating valve roof anchorage has spring lower seat, also is provided with the spring that connects the spring seat of honour and spring lower seat in the said valve cover.
The control piston of described oil and water seperator combination brake switch and proporting; It is characterized in that: form annular convex ring on the said annular table; Form the stationary annular groove between said annular convex ring and the piston body outer wall; Said diaphragm central bottom forms annular buckle, and the annular buckle of diaphragm snaps in the said stationary annular groove with spacing.
The control piston of described oil and water seperator combination brake switch and proporting is characterized in that: said diaphragm has the annular portion that arches upward, and said diaphragm pressing plate is by being the basin body shape, and diaphragm pressing plate bottom is pressed in the diaphragm annular and arches upward in the middle of the portion to compress diaphragm.
The utility model is simple in structure, is easy to realize, through being covered with the valve cover on piston body top; And the valve cover is pressed on diaphragm presents a theatrical performance as the last item on a programme, and not only can fixedly secure diaphragm, also the regulating valve in the valve cover is played sealing process simultaneously; Prolonged the working life of control piston; Annular convex ring on the piston body annular table and piston body outer wall constitute the stationary annular groove, realize the stable installation of diaphragm with being clasped of diaphragm, have effectively improved the stability of pistons work.The utility model can effectively improve the control piston working stability of oil and water seperator combination brake switch and proporting, the working life of also having improved control piston.
