Abstract
The utility model relates to a double shuttle valve. The double shuttle valve comprises a connecting screw sleeve and a valve sleeve which are connected with each other, the valve sleeve is provided with a radial hole, a valve body is arranged in the valve sleeve, the valve body is composed of two cone valve cores, the two cone valve cores are matched with flow channels in the connecting screw sleeve and the valve sleeve respectively, and springs are arranged in the two cone valve cores. According to the double shuttle valve, the two valve cores are utilized in the valve body to replace an original steel ball, so that another two ports and a public port can be communicated in one-way mode, when the public port is under pressure, the public port and another two ports are not communicated, and thereby the requirement is met. Besides, the double shuttle valve has the advantages of being simple in structure, convenient to disassemble and assemble and rapid in maintenance.
Description
Technical field
The utility model relates to a kind of liquid (gas) pressure device of one-way flow, relates in particular to a kind of pair of shuttle valve.
Background technique
At present, what have now and once had is combined by valve body, steel ball, plug screw about shuttle valve, and when an end advanced pressure oil (gas), logical with common port, the other end was obstructed.But in some cases, need keep certain pressure at the common port end, at this moment, in other two mouthfuls of needs sealings.And this class formation is not sure of steel ball and can be partial to which limit and more reach requirement (this direction is at random).
Summary of the invention
To defective of the prior art, the utility model provides a kind of common port that realizes to keep two shuttle valves of the requirement of certain pressure.
For reaching the technological scheme that above-mentioned model utility purpose the utility model adopted be: two shuttle valves; Comprise the connection swivel nut and the valve pocket that are connected; Be shaped on radial hole on the said valve pocket, be provided with valve body in the said valve pocket, it is characterized in that said valve body is made up of two poppet valve cores; Said two poppet valve cores respectively with saidly be connected the runner in the swivel nut, the runner in the valve pocket matches, and is provided with spring in said two poppet valve cores.
Between said connection swivel nut and the said valve pocket through being threaded.
The end of the threaded connection place of said connection swivel nut and said valve pocket is shaped on projection.
The utility model adopts two poppet valve cores at valve inner, replaces an original steel ball, make its in addition two mouthfuls can both unidirectionally connect to common port, when there is pressure in common port, common port arrive other two mouthfuls all obstructed, thereby reach requirement.And the utility model also has simple in structurely, and easy accessibility overhauls advantage efficiently.
Further specify below in conjunction with the mode of execution of accompanying drawing the utility model.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiments of the utility model.
Embodiment
As shown in Figure 1, two shuttle valves comprise connecting swivel nut 1 and valve pocket 4 that said connection swivel nut 1 right-hand member is shaped on internal thread, and said valve pocket 4 left ends are shaped on outside thread, connect swivel nut 1 and cooperate realization to be connected with valve pocket 4 through internal thread and outside thread.Also be shaped on radial hole 41 on the said valve pocket 4; Be provided with valve body 2 in the said valve pocket 4, said valve body 2 is made up of two poppet valve cores 21, is shaped on spring seat in the said poppet valve core 21; Be provided with spring in the said spring seat, the two ends of said spring contact with said poppet valve core 21 respectively mutually.The structure of said two poppet valve cores 21 matches with said runner, the valve pocket 4 interior runners that are connected in the swivel nut 1 respectively, when poppet valve core 21 and above-mentioned runner contact, can realize sealing.Said connection swivel nut 1 is shaped on projection 42 with the end of the threaded connection place of said valve pocket 4, prevents that effectively valve pocket 4 from coming off.
The working principle of the utility model is following: when the logical pressure oil (gas) of A end, force A end poppet valve core 21 moves to right-hand member, thereby A mouth and common port P are communicated; When the B end led to pressure oil (gas), liquid (gas) force B end poppet valve core moved to left end, thereby B mouth and common port P are communicated; When common port P led to pressure oil (gas), liquid (gas) pressure made A end cone valve, and B end poppet valve core is all pressed to valve port separately, thereby P is not all communicated to A, B, realizes required function.
More than describe the preferred embodiment of the utility model in detail.The ordinary skill that should be appreciated that related domain need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art, all should fall in the protection domain of the utility model on the basis of existing technology through the available technological scheme of logical analysis, reasoning, or a limited experiment according to the design of the utility model.
Claims (3)
1. two shuttle valve; Comprise the connection swivel nut (1) and the valve pocket (4) that are connected; Be shaped on radial hole (41) on the said valve pocket (4), be provided with valve body (2) in the said valve pocket (4), it is characterized in that said valve body (2) is made up of two poppet valve cores (21); Said two poppet valve cores (21) match with said runner, the interior runner of valve pocket (4) that is connected in the swivel nut (1) respectively, are provided with spring in said two poppet valve cores (21).
