An object of the utility model is to provide an adjusting lever is changed convenient bypass valve and is adjusted the structure, has following advantage: 1, can adjust bypass valve pressure, 2, utilize bolt regulation pressure, it is convenient to adjust, and it is convenient to change, low cost, 3, prevent effectively that the adjusting lever from losing.
Description
Technical field
This utility model relates to a kind of bypass valve assembly, more specifically, it relates to a kind of bypass valve governor motion.
Background technology
nullAt present，The Chinese patent of disclosure (bulletin) number CN104121373A on market discloses a kind of adjustable-pressure bypass valve，It includes shell、Water inlet on the housing and outlet are set、The connecting pipe that described water inlet is connected with described outlet、It is arranged on the plug of described cover top portion and is positioned at described connecting pipe and for controlling the valve core device of the on off operating mode of described water inlet and described outlet，Described valve core device includes the valve body being fixed on described connecting pipe、It is arranged on described valve body and sealing block that in the vertical direction coordinates with described valve body slides、And the adjusting lever of described plug threaded engagement and be arranged on the compression spring between described adjusting lever and described sealing block，The base plate of described valve body is provided with through hole，Described adjusting lever is slidably matched with described sealing block，Described sealing block states through hole in the effect lower cover residence of described compression spring，Described adjusting lever top is stretched out outside described plug.
This adjustable-pressure bypass valve, although can regulate pressure parameter, but owing to adjusting lever stretches out easy corrupted outside plug, and once its replacing is the most loaded down with trivial details after adjusting lever corrupted.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of adjusting lever to change convenient bypass valve adjustment structure.
For achieving the above object, this utility model provides following technical scheme: a kind of bypass valve governor motion, including adjusting part, this adjusting part be arranged on a hollow valve body (in, the spool blocked between its import and outlet it is provided with in valve body, and one end conflict spool, other end conflict valve body thus keep spool to close the spring of import and outlet, wherein: described adjusting part includes padding the slide block being located between spring and valve body, the adjusting lever being located on valve body and conflict with slide block, this adjusting lever longitudinal sliding motion is connected to valve body, also include the latch-up structure limiting adjusting lever axial location.
By adjusting the axial location of adjusting lever and being locked by latch-up structure spacing, thus control slide block location in valve body, and the change in location of slide block can make spring be in compressive state in various degree by extrusion spring, realize adjusting spool and close import, the pressure of outlet, be finally reached the purpose of the minimum pressure adjusting bypass valve pressure release.Although adjusting lever is still in outside valve body, but adjusting lever is separately positioned with slide block, even if adjusting lever damages, the replacing of adjusting lever is the most simple and convenient.
Further, described latch-up structure includes the external screw thread being arranged on described adjusting lever and is arranged on described valve body the internal thread hole coordinated with this external screw thread.
The helicitic texture that utilization cooperates is as the latch-up structure of locking adjusting lever position, and its processing is simple and convenient to operate.Overall simple is effective.
Further, the outer end of described adjusting lever is provided with hexagonal nut.
Can conveniently be operated by nut, rotate adjusting lever, and nut is as the protrusion on adjusting lever, moreover it is possible to play the limit effect preventing adjusting lever from falling into valve body.
Further, the connector of bar shaped it is provided with between described nut and valve body.
Adjusting lever is avoided to be accidentally lost when taking out.
Further, it is provided with disjunction in the middle part of described connector, engages the buckle of this connector.
Buckle structure is utilized conveniently to be isolated from valve body by adjusting lever, convenient operation.
By using technique scheme, this utility model has the advantage that 1, can regulate bypass valve pressure；2, utilizing bolt to regulate pressure, easy to adjust, it is convenient to change, with low cost；3, effectively prevent adjusting lever from losing.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment one: as it is shown in figure 1, a kind of bypass valve governor motion, being arranged in bypass valve, this bypass valve includes the valve body 1 of a hollow, and the lower end of valve body 1 is import 11, enters for medium；The side of valve body 1 is provided with outlet 12, flows out for medium.Being provided with valve seat 13, the i.e. table top of a level between import 11 and outlet 12, on valve seat 13, a closely connected spool 2, is provided with spring 3 between spool 2 and valve body 1, utilizes spring 3 to withstand on valve seat 13 by spool 2, it is achieved the closing of valve body 1.When the pressure medium in import 11 exceedes spring 3 to the pressure of spool 2, spool 2 is opened, and medium is from outlet 12 outflow.Realize medium pressure release.
Having through hole above valve body 1, wear an adjusting lever 5 in through hole, adjusting lever 5 lower end arranges a slide block 4, slide block 4 is conflicted with spring 3 upper end, when extruding adjusting lever 5 and making it move down, slide block 4 moves down compression spring 3 therewith, thus increases the pressure that spool 2 is applied by spring 3.And then strengthen open the pressure needed for spool 2.
Being provided with position limiting structure on valve body 1 in order to limit the axial location of adjusting lever 5, the concrete scheme of this position limiting structure is as follows: fixing on through hole connect one with the nut of internal thread hole 6, and the outside of adjusting lever 5 arranges external screw thread, and both cooperate.
Except above-mentioned position limiting structure, it is also possible to by changing adjusting lever 5, the mode of the weight changing adjusting lever 5 limits the position of adjusting lever 5.It can in addition contain realize the position of adjusting lever 5 by arranging the structure such as buckle, bar shaped tooth outside valve body 1.
Embodiment two: with differing only in of embodiment one, directly adjusting lever 5 is set to bolt, on the one hand the screw thread of its end facilitates operation adjustment bar 5, and on the other hand it prevents adjusting lever 5 to be absorbed in the effect of valve body 1.Connecting a connection piece 8 on nut 7, this connector 8 other end is fixedly connected on valve body 1 simultaneously.This connector 8 can use chain, steel wire etc..One buckle 9 structure is set in the centre of connector 8, for quickly disconnecting, merging this connector 8.
