Abstract
The utility model discloses a kind of equilibrium valve, comprise valve body, left cover and right cover, described left cover is connected on the left of valve body, described right cover is connected on the right side of valve body, described left cover is provided with opening one, described valve body is provided with opening two, run through in described left cover and have piston, described piston rear is connected with balance valve rod, described balance valve rod rear is provided with valve seat, and described valve seat rear is connected with spring one, is provided with spring two in described right cover, described spring one links with spring two, is provided with through hole between described piston and balance valve rod; This equilibrium valve better quality, can not make fluid reflux, and oil pressure balance is stablized, and compact structure.
Description
Technical field
The utility model relates to a kind of equilibrium valve.
Background technique
Equilibrium valve is a kind of valve of specific function, and valve itself, without special way, is only to have any different in using function and place.In some industry, because medium (all kinds of flowable materials) exists larger pressure difference or difference in flow in the various piece of pipeline or container, for reducing or balancing this difference, valve is installed between corresponding pipeline or container, in order to regulate the relative equilibrium of pressure at both sides, or the balance of flow is reached by the method for shunting, this valve is just equilibrium valve.
Existing equilibrium valve is second-rate, and easily occurs fluid reflux, and oil pressure is stable not, and loosely organized.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of better quality, and can not make fluid reflux, oil pressure balance is stablized, and the equilibrium valve of compact structure.
For solving the problem, the utility model adopts following technological scheme:
A kind of equilibrium valve, comprise valve body, left cover and right cover, described left cover is connected on the left of valve body, described right cover is connected on the right side of valve body, described left cover is provided with opening one, and described valve body is provided with opening two, and running through in described left cover has piston, described piston rear is connected with balance valve rod, described balance valve rod rear is provided with valve seat, and described valve seat rear is connected with spring one, is provided with spring two in described right cover, described spring one links with spring two, is provided with through hole between described piston and balance valve rod.
As preferably, described valve body is one-way valve valve body.
As preferably, described piston is arranged for sealing.
The beneficial effects of the utility model are: the built-in one-way valve of valve body does not make fluid reflux; Piston utilizes clearance seal, requires that high quality is good; Balance valve rod utilizes rearmounted valve seat to reach damping function, and oil pressure balance is stablized; The compact good airproof performance of this valve arrangement, can form a loop voluntarily, is an important element on loop wheel machine.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of a kind of equilibrium valve of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of equilibrium valve, comprise valve body 1, left cover 2 and right cover 3, described left cover 2 is connected on the left of valve body 1, described right cover 3 is connected on the right side of valve body 1, described left cover 2 is provided with opening 1, described valve body 1 is provided with opening 25, run through in described left cover 2 and have piston 6, described piston 6 rear is connected with balance valve rod 7, and described balance valve rod 7 rear is provided with valve seat 8, described valve seat 8 rear is connected with spring 1, be provided with spring 2 10 in described right cover 3, described spring 1 links with spring 2 10, is provided with through hole 11 between described piston 6 and balance valve rod 7.
Described valve body 1 is one-way valve valve body.
Described piston 6 is sealing setting.
Operating procedure:
1. utilize opening one pilot control, promote piston and back down equilibrium valve bar, make fluid enter opening two;
2. close opening one, balance valve rod, due to spring one and the active force reinstatement of spring two, closes oil circuit.
The beneficial effects of the utility model are: the built-in one-way valve of valve body does not make fluid reflux; Piston utilizes clearance seal, requires that high quality is good; Balance valve rod utilizes rearmounted valve seat to reach damping function, and oil pressure balance is stablized; The compact good airproof performance of this valve arrangement, can form a loop voluntarily, is an important element on loop wheel machine.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
Claims (3)
1. an equilibrium valve, it is characterized in that: comprise valve body, left cover and right cover, described left cover is connected on the left of valve body, described right cover is connected on the right side of valve body, described left cover is provided with opening one, described valve body is provided with opening two, run through in described left cover and have piston, described piston rear is connected with balance valve rod, described balance valve rod rear is provided with valve seat, and described valve seat rear is connected with spring one, is provided with spring two in described right cover, described spring one links with spring two, is provided with through hole between described piston and balance valve rod.
2. equilibrium valve according to claim 1, is characterized in that: described valve body is one-way valve valve body.
3. equilibrium valve according to claim 1, is characterized in that: described piston is sealing setting.
