Abstract
The utility model discloses a double valve plate control structure of a tube force control valve, which comprises a small valve plate (8), a control rod (3), a valve shaft (9), a valve body (1), a large valve plate (2), and a discharge orifice (7) arranged on the large valve plate (2). One end of a small valve plate handle (5) is articulated with the valve shaft (9) and is concentric with the convolution center of the large valve plate (2); the small valve plate (8) is installed at the other end of the small valve plate handle (5); one end of a connecting rod (4) is articulated with the end part of the control rod (3); and the other end is articulated with one end of the small valve plate (8) installed on the small valve plate handle (5). When the caliber of the valve is not larger than DN 200, the small valve plate (8) can be connected with the small valve plate handle (5) into a whole, and the form is not changed. The double valve plate control structure is a small valve plate slowly-closing structure with the advantages of security, reliability, convenient maintenance and debugging, simple structure, low cost and reliable performance.
Description
Technical field
The utility model relates to a kind of structural type of valve part, particularly relates to a kind of little valve plate with Slow Close function that adopts the valve of pipeline fluid power control.
Background technique
A kind of pipe force control valve (ZL200620051914.1) is arranged at present, its structure is that the valve shaft by the both sides symmetry is hinged with a big valve plate in the valve body, have discharge orifice on the big valve plate, slide block one end is contained on the described big valve plate by bearing pin and torsion spring hinge, it is corresponding with discharge orifice on the described big valve plate that the described slide block the other end is provided with little valve plate, be provided with piston cylinder and piston at described valve body top, on described piston, be provided with piston rod with the corresponding apical grafting of described slide block.For reaching the closing velocity of being controlled little valve plate when closing valve by piston cylinder, slide block adopts torsion spring to support, and slide block is contacted with piston rod all the time.But adopt torsion spring to have the shortcoming that can't regulate, little to operating mode accommodation.There is the high shortcoming of processing request relatively in torsion spring simultaneously, otherwise torsion is little, and the life-span is short, is unfavorable for the stability and the security requirement of valve.
The model utility content
Technical problem to be solved in the utility model provides a kind of safe and reliable, and maintenance and debugging is managed force control valve bivalve plate control structure easily.
In order to solve the problems of the technologies described above, the pipe force control valve bivalve plate control structure that the utility model provides, comprise little valve plate, controlling rod, valve shaft, valve body, big valve plate, be opened in the discharge orifice on the big valve plate, little valve plate handle one end is hinged on the described valve shaft concentric with the centre of gyration of described big valve plate, the other end of described little valve plate handle is equipped with described little valve plate, connecting rod one end and described controlling rod end are hinged, and the end that described little valve plate is installed on the other end and the described little valve plate handle is hinged.
Described controlling rod is hinged by first bearing pin and described connecting rod, and described connecting rod is hinged by second bearing pin and described little valve plate handle.
Adopt the pipe force control valve bivalve plate control structure of technique scheme, when driving valve: little valve plate can be controlled, make big valve plate retrained by little valve plate, together slowly open under controlling rod and connecting rod effect; Close valve: big valve plate fast quick-closing valve under deadweight and waterpower impetus, the control of controlled bar of little valve plate and connecting rod is slowly closed with the decline of controlling rod, and fit fully with the discharge orifice on the big valve plate in the final plant closure position.
In sum, the utility model is a kind of safe and reliable, and maintenance and debugging is convenient and simple in structure, with low cost, the pipe force control valve bivalve plate control structure of reliable performance.

Schematic representation when Fig. 3 is valve closing;
Fig. 4 is an Open valve process schematic representation;
Fig. 5 closes valve process schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, controlling rod 3 penetrates from the hole at valve body 1 top, and an end of controlling rod 3 ends and connecting rod 4 is hinged by pivot pin 61; One end of the other end of connecting rod 4 and little valve plate handle 5 is hinged by pivot pin 6; The other end of little valve plate handle 5 is hinged on the valve shaft 9, and is concentric with the centre of gyration of big valve plate 2, and little valve plate 8 is installed on the other end of little valve plate handle 5, and little valve plate 8 is fitted fully with the discharge orifice 7 on the big valve plate 2 under the valve complete shut-down state.When valve aperture at DN200 and when following, little valve plate 8 and little valve plate handle 5 can be connected as a single entity, other forms are constant.
Drive valve, referring to Fig. 1, Fig. 3 and Fig. 4, open pump before, valve is under the effect of outlet end pressure of return water, controlling rod 3 is pushed down little valve plate handle 5 by connecting rod 4, makes little valve plate 8 be close to big valve plate 2, valve is in closes sealing state.After opening pump, under the control effect, entrance point reaches certain pressure outside other, and controlling rod 3 slowly up moves back, and little valve plate 8 slowly opens to synchronously with big valve plate 2 and reaches traffic requirement.
Close valve, referring to Fig. 5, during termination of pumping, pipe flow speed descends rapidly, and big valve plate 2 is closed in action of gravity following moment and blocked most of current, eliminates water hammer by discharge orifice 7 draining pressure releases.Little valve plate 8 controlled bars 3 are by the restraining function of connecting rod 4.Pressure release finishes, and under the control effect outside, controlling rod 3 slowly descends, and realizes finally that little valve plate 8 is fitted fully with the discharge orifice 7 on the big valve plate 2 to finish the pass valve, and valve is got back to the beginning state that opens.
Claims (2)
1, a kind of pipe force control valve bivalve plate control structure, comprise little valve plate (8), controlling rod (3), valve shaft (9), valve body (1), big valve plate (2), be opened in the discharge orifice (7) on the big valve plate (2), it is characterized in that: little valve plate handle (5) one ends are hinged on described valve shaft (9) and go up concentric with the centre of gyration of described big valve plate (2), the other end of described little valve plate handle (5) is equipped with described little valve plate (8), connecting rod (4) one ends and described controlling rod (3) end are hinged, and the end that described little valve plate (8) is installed on the other end and the described little valve plate handle (5) is hinged.
