Description
Technical field
This utility model relates to a kind of Pre-loaded one-way valve, relates generally to valve body field.
Background technology
Can be often in contact with to one-way valve structures in life, through check valve, fluid can only one-way flow, and for even
Connecing the joint of air-out hose, the other end of air-out hose is connected with the gas utensil electrical equipment such as gas kitchen ranges, gas heater again.Existing
Gas pressure regulating valve the biggest and structure complicated, be less able to set the most in advance the effect of pressure regulation
Really.
Utility model content
For above the deficiencies in the prior art, the utility model proposes a kind of Pre-loaded one-way valve being adjusted flexibly.
For reaching above-mentioned purpose, the technical solution of the utility model is: include straight tube valve body, at straight tube valve end screw thread
Being combined with pretension block, this pretension block is provided with through hole, is sliding combined with connecting rod in through hole, and the right-hand member of connecting rod is provided with double nut
Carrying out spacing, the left end in connecting rod is fixed with spool, and spool is slidably fitted in straight tube valve inner, in the space of valve core movement
Straight tube body wall be provided with bypass pipe.
Know-why of the present utility model is as follows: spool is slidably fitted in straight tube valve body, and the right-hand member of spool is fixed simultaneously
In connecting rod, outer in connecting rod be arranged with spring, when spool not by ambient pressure when, in the elastic force effect of spring
Under, spool slides to the left, spool by straight tube body wall the bypass pipe mouth of pipe sealing, straight tube valve body the most now and
Bypass pipe does not the most connect.When liquid from straight tube valve body enter, when the left side of spool by fluid pressure when, spool will
Pressure transmission to spring, spring be under pressure generation deformation compression, when the pressure of liquid is increased sufficiently to big degree, spool to
Slide in right side, to such an extent as to the connector of straight tube valve body connection bypass pipe is opened by spool, and now, liquid enters from straight tube valve body
In bypass pipe.Fluid pressure in straight tube valve body is the biggest, and the distance that spool slides to the right is the biggest, and straight tube valve body and bypass pipe are even
Logical bore is the biggest.When the fluid pressure of straight-through other pipe diminishes when, the even fluid pressure of bypass pipe has been more than directly
The pressure of pipe valve body, spool slides to the left, and then the liquid in bypass pipe enters the passage obstruct in straight tube valve body, bypass pipe
Entering on the direction of straight tube valve body, spool cannot be made a concession, and therefore, i.e. liquid cannot lead to by promoting the movement of spool to open one
Road enters in straight tube valve body, and then realizes the function of check valve.Owing to connecting rod is slidably fitted on the through hole of pretension block, therefore
By rotating pretension block, to the left or the position of the pretension block that moves right just can control the range of activity of spool.If pretension block to
If moving left, will make spool that the obstruct of liquid in straight tube valve body to be put more effort, to by straight tube valve body and bypass pipe；Even
Connection road is got through, spool must slide to the right longer distance, the elastic force of spring also can be the biggest, say, that needs bigger
Fluid pressure spool could be promoted to the right and then the passage of straight tube valve body and bypass pipe is opened.
The beneficial effects of the utility model are as follows: pretension block and spool are fixed together by connecting rod, to the left or
Slip pretension block to the right, will directly change the range of activity of spool, so control that liquid enters that spool in bypass pipe slides away from
From.The pretightning force of one-way flow and the scope that spool is movable can be set in advance.The most ultimate attainment situation: be moved to the left pre-
The interface channel of straight tube valve body and bypass pipe can be blocked by tight block completely, i.e. closes the circulation of pipeline, moves right to permissible
Fully open the passage of straight tube valve body and bypass pipe.
Further, the valve body on the left of spool is provided with and limits the internal projection that spool is moved to the left, and adopts in this way, permissible
Prevent from being moved to the left spool is too much, even the interface of bypass pipe is leaked right side at spool cruelly.
Further, spool is provided with the radial hole and axial hole being interconnected, and radial hole and axial hole are arranged on spool
On, straight tube valve body and by-pass valve body connection could must be connected by radial hole and axial hole, radial hole is arranged on spool
Middle part, therefore liquid can only improve, by flowing in the middle part of spool, the closure that bypass pipe is made an excuse by spool.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
In description, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only that this practicality is new
Wherein two width of type, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to root
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of this utility model embodiment.
Wherein, 1-straight tube valve body, 2-spool, 201-radial hole, 202-axial hole, 4-pretension block, 501-double nut,
502-connecting rod, 6-internal projection.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in this utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only preferred embodiment of the present utility model rather than whole embodiments.Based in this utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all
Belong to the scope of this utility model protection.
Embodiment
This utility model embodiment is as follows:
Including horizontally disposed arm valve body as shown in Figure 1, the right-hand member end thread at straight tube valve body 1 is combined with pretension block
4, pretension block 4 is provided with the through hole of level, runs through in through hole and be sliding combined with connecting rod 502, connecting rod 502 the right side
Hold by coordinating double nut in connecting rod 502 spacing, use double nut 501 can in connecting rod 502 the appointing of thread segment
Where side locks, in order to control the length at double nut 501 left-side connecting bar 502, and the left end in connecting rod 502 connects valve
Core 2 is cased with spring on the contiguous block between pretension block 4 and spool 2, this spring by spool 2 to the left against.
Spool 2 without the effect of external force when by spring to against, spool 2 by acting force of the spring, spring-compressed,
Spool 2 slides to the right, and the sidewall of the straight tube valve body 1 in the range of spool 2 horizontally slips is provided with and portals, and this upper connection of portalling has
Bypass pipe.
Spool 2 left end is provided with axial hole 202, is provided with radial hole 201 in the middle part of the sidewall of spool 2, this radial hole 201 and axle
Connect on spool 2 to hole 202.
Being provided with internal projection 6 on the valve body in the left side of spool 2, lid internal projection 6 prevents spool 2 from sliding to the left too much.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
