Abstract
The utility model discloses a double linked one-way valve group comprising a valve body 7, wherein two lateral cavities are arranged in the valve body 7, and the two cavities are communicated with each other; one end of one cavity is an upper oil inlet A1 and one end of the other cavity is a lower oil outlet A2; and a valve seat 6 is arranged in the cavity, a slide valve 4 is arranged in the valve seat 6, an O-shaped ring 5 is arranged at the connection part of the valve seat 6 and the valve body 7, a pressure spring 3 is arranged in the slide valve 4, and a gland 2 is arranged at the rear end of the pressure spring 3. The utility model has the advantages that: the design of the double linked one-way valve group not only has lower price than two common one-way valves, but also saves material and improves the rapidity of mass production, and the failure of one group of one-way valves can not affect the performance of the other group of one-way valves.
Description
Technical field
The utility model relates to oil pump one and is equipped with the hydraulic system that usefulness or two oil circuits are incorporated in a road binders, and particularly a usefulness or two oil circuits are incorporated in the one-way valve group of the hydraulic system of a road binders to oil pump one fully.
Background technique
Existing control oil pump one is equipped with the hydraulic system that usefulness or two oil circuits are incorporated in a road binders, generally all is to adopt two independent one-way valves to realize, this complex structure, and the cost height, processing bothers.
The model utility content
At the defective of prior art, the utility model provides a kind of duplex one-way valve group.
The technical scheme in the invention for solving the above technical problem is:
Duplex one-way valve group, comprise valve body 7, nonreturn valve core, it is characterized in that, be provided with two transverse passageway in the valve body 7, and two cavitys communicate, one end of cavity is last filler opening A1, following filler opening A2, valve seat 6 is arranged in the cavity, be provided with guiding valve 4 in the valve seat 6, valve seat 6 is provided with O shape circle 5 with the contacting point of valve body 7, stage clip 3 is arranged in the guiding valve 4, and the end of stage clip 3 is provided with gland 2, and there is screw plug 1 on top, gland 2 back, last filler opening A1, following filler opening A2 is narrower than the width of valve seat 6, stage clip 3 withstands filler opening A1, following filler opening A2, being respectively arranged with up and down and last filler opening A1 of valve body 7, the last oil outlet B that following filler opening A2 is vertical, following oil outlet C, and down oil outlet C is provided with and is used for the plug screw 9 of shutoff.
Described nonreturn valve core is arranged in the valve body 7;
Described plug screw 9 is threaded with following oil outlet C, and is provided with packing ring 8 between plug screw 9 and the valve body 7.
The beneficial effects of the utility model: the appearance of duplex one-way valve group not only is being lower than two common one-way valves in price, and saved the waste of material and improved the rapidity of producing in batch, also can not influence other one group of valve because of the inefficacy of one group of one-way valve wherein at aspect of performance; Duplex one-way valve group equally also makes the user save the required accessory of pipeline, improves the integrated degree of hydraulic system.
Description of drawings
Fig. 1, structural representation of the present utility model.
Fig. 2, be equipped with the hydraulic system that a usefulness is passed through with the oil pump one of functional symbolic representation.
Fig. 3, be incorporated in the hydraulic system of a road binders with two oil circuits of functional symbolic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Duplex one-way valve group is a kind of the parallel one-way valve that two one-way valves (import difference, outlet link to each other) merge and outlet lumps together, two one-way valve P1, P2.Make fluid one-way flow, reverse check simultaneously.Duplex one-way valve group, comprise valve body 7, be provided with two transverse passageway in the valve body 7, and two cavitys communicate, one end of cavity is last filler opening A1, following filler opening A2, and valve seat 6 is arranged in the cavity, is provided with guiding valve 4 in the valve seat 6, valve seat 6 is provided with O shape circle 5 with the contacting point of valve body 7, by withstanding filler opening A1, following filler opening A2 by stage clip 3 between guiding valve 4 and the gland 2.There is screw plug 1 on top, gland 2 back, valve body 7 be respectively arranged with up and down and last filler opening A1, filler opening A2 is vertical down last oil outlet B, oil outlet C, and following oil outlet C down are provided with and are used for the plug screw 9 of shutoff, and the user can select this mouthful external as required.Described plug screw 9 is threaded with following oil outlet C, and is provided with packing ring 8 between plug screw 9 and the valve body 7.To have and load onto the valve seat 6 that has O shape circle 5 in the valve body 7 in two chambeies respectively, the guiding valve that stage clip 3 is housed is packed into has the gland and the screw plug 1 of O shape circle 5 on valve seat 6 and the upper cover, and following oil outlet C then blocks with the plug screw 9 that has packing ring 8.During use, will go up filler opening A1, down filler opening A2 receives filler opening respectively, when pressure reached the pressure that spring sets up, guiding valve 4 was opened, pressure oil is from last oil outlet B, oil outlet C flows out down, the C mouth can be selected for use according to client's demand.
