Description
Technical field
The utility model relates to two-way valve technical field more particularly to a kind of two-way controllable valves.
Background technique
Two-way controllable valve effect is to prevent the liquid medium in pipeline from flowing backwards.The pressure of fluid media (medium) is leaned in the opening and closing of valve
Power.Valve only includes a water inlet and a water outlet, is a flow direction of valve from water inlet to water outlet, from water outlet into
The mouth of a river is another flow direction of valve.And valve can be connected in a flow direction, another direction cannot be connected.
When two-way controllable valve is set in double acting hydraulic cylinder, since one side hydraulic cylinder dismantles difficult, another aspect
Hydraulic cylinder internal work inclement condition, so the reliability requirement to two-way controllable valve is higher, to reduce maintenance time as far as possible
Number.And in order to further increase the reliability of two-way controllable valve, any sensing is all preferably not provided with using mechanical structure
Device.
To sum up, it is simple how to provide a kind of structure, the two-way controllable valve of high reliablity leads between two ports to realize
The fluid crossed can be switched on from both direction, be those skilled in the art's urgent problem to be solved.
Utility model content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, propose a kind of two-way controllable valve, solve the prior art
The not high enough technical problem of the reliability of middle two-way controllable valve.
In order to reach above-mentioned technical purpose, the utility model embodiment provides a kind of two-way controllable valve, this is two-way controllable
Valve includes: shell, block, spring and striker, which is characterized in that shell both ends open, inside include that a connection two is opened
Mouth crosses oil pocket, and two blocks are connected by spring, were built in oil pocket, and abut with outer casing inner wall, opens for closing
Mouthful, striker is connect with two blocks respectively, is extended to outside shell by opening.
Compared with prior art, the utility model has the following beneficial effects: the two-way controllable valve of the utility model uses
Pure mechanic structure design, inside do not include the electronic equipments such as sensor, controller, and overall construction design is simple, pure mechanic structure
High reliablity can satisfy the requirement to be worked long hours under High Voltage environment without failure, can widely be employed
Inside hydraulic device, for controlling the connection situation of two-way controllable valve pressure at two ends oil.
Detailed description of the invention
Fig. 1 is the cross-sectional view of two-way controllable valve provided by the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Referring to Figure 1, Fig. 1 is the cross-sectional view of two-way controllable valve provided by the utility model.
Two-way controllable valve includes: shell 1, block 2, spring 3 and striker 4.
Oil pocket is crossed including two openings of a connection in 1 both ends open of shell, inside.Two blocks 2 are connected by spring 3
It connects, was built in oil pocket, under the elastic force effect of spring 3, be pressed on 1 inner wall of shell, for closing opening.In order to more
Good makes the closing opening of block 2, avoids oil leak, and 1 inner wall of shell is designed to the shape of fitting block 2, resistance close to opening
Chock 2 can be designed to a variety of different shapes, such as: ball-type, pyramid type etc., so that it is compressing shell 1 and is being detached from shell 1
Conversion is smoothly realized in the two states, is not easy to be stuck.Striker 4 is connect with two blocks 2 respectively, is extended to by opening
Outside shell 1.Striker 4 and spring 3 are coaxially disposed, in order to which striker 4 pushes 2 compressed spring 3 of block.
Two-way controllable valve is generally mounted on the piston in double acting hydraulic cylinder in use process, opening on shell 1
Mouth connection piston two sides, are respectively designated as the side A and the side B for ease of description.When the side A is passed through pressure oil, piston is pushed
It is moved to the side B.The block 2 that the pressure of A lateral pressure oil is pushed closer to the side A is moved to the side B, so that A side opening is opened, pressure oil
It entered in oil pocket.But the elastic force of the pressure of pressure oil and spring 3 makes the side B block 2 compress shell 1 simultaneously, closes the side B
Opening, ensure that during piston motion, cross oil pocket be in closed state, the two sides A, B are not connected to.When piston motion to B
When the end of side, the striker 4 close to the side B hits the hydraulic inside wall of cylinder, and the anti-block 2 for pushing away the side B is moved to the side A, so that the opening of the side B
It opens, so that crossing, oil pocket is in the open state, and the pressure oil of the side A can flow to the side B by crossing oil pocket.Likewise, when changing pressure
The direction of power oil, so that pressure oil is fashionable from B effluent, the effect of generation is identical as from the inflow of the side A.
Implement the utility model embodiment, has the following beneficial effects: the two-way controllable valve of the utility model using pure machine
The design of tool structure, inside do not include the electronic equipments such as sensor, controller, and overall construction design is simple, and pure mechanic structure is reliable
Property it is high, can satisfy the requirement to be worked long hours under High Voltage environment without failure, can widely be employed for liquid
It presses inside equipment, for controlling the connection situation of two-way controllable valve pressure at two ends oil.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
