Description
Technical field
The utility model relates to a kind of valve, especially it is a kind of can pressure release floating ball valve.
Background technique
Floating ball valve is small in size, light-weight, and structure is simple, and sphere has the function of free floating, can preferably guarantee to seal；
Ball valve is to use the sphere with circular through hole as opening and closing element, makees 0 ~ 90 degree of rotation around valve rod center in valve rod driving lower sphere
Turn, completes opening and closing function；Have the characteristics that compact-sized switch is rapid, rotate 90 degree, valve can be closed, cutting pipeline is situated between
Matter；Sphere channel diameter is identical as pipeline diameter, and flow resistance is small, and negotiability is big；Valve rod is down-mounting type, has prevented what valve rod was pierced by
Accident occurs, and ensure that using safe.But floating ball valve is due to its design feature, unbearable biggish pressure, when liquid in valve
When body pressure is larger, sphere is easy to happen offset, or even damage.
Summary of the invention
The technical problem to be solved by the utility model is to provide it is a kind of can pressure release floating ball valve, when the liquid pressure in valve
When power is larger, liquid can be discharged
In order to solve the above technical problems, the technical scheme adopted by the utility model is: it is a kind of can pressure release floating ball valve,
Including valve body, sphere and valve seat are equipped in valve body, the valve seat is set to the left and right ends of sphere, and the upper end of the sphere is equipped with
Valve rod, the valve rod and sphere and valve body are rotatablely connected, and the valve body includes water inlet end and water outlet, in the side at valve inleting water end
It is fixedly connected with overflow pipe on wall, overflow mechanism is equipped in overflow pipe.
Preferably, the overflow mechanism is set to the lower end of overflow pipe, including upper annular stop backstop and lower annular stop are stopped
Gear is equipped with sealing plate in upper annular stop backstop and lower annular stop backstop, is equipped between sealing plate and upper annular stop backstop
The upper end of holddown spring, the overflow pipe is equipped with opening.
Preferably, the top of the upper annular stop backstop is equipped with the kickboard gone up and down with liquid level, and mark is equipped in kickboard
Bar.
Preferably, the upper surface of the kickboard and the lower surface of sealing plate are equipped with rubber coating.
Preferably, it is also connected with drain pipe on the side wall of the overflow pipe, is threaded in the output end of drain pipe close
Tube sealing cap.
The utility model provide it is a kind of can pressure release floating ball valve, overflow pipe and overflow mechanism are set, when the liquid in valve
When body pressure is greater than the pressing force of holddown spring, liquid jacks up sealing plate, flows liquid into overflow pipe, carries out pressure release processing.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model overflow pipe.
Specific embodiment
As shown in Figure 1, it is a kind of can pressure release floating ball valve, including valve body 1 is equipped with sphere 2 and valve seat 3, institute in valve body 1
The left and right ends that valve seat 3 is set to sphere 1 are stated, the upper end of the sphere 2 is equipped with valve rod 4, the valve rod 4 and sphere 2 and 1 turn of valve body
Dynamic connection, the valve body 1 include water inlet end and water outlet, and overflow pipe 5, In is fixedly connected on the side wall of 1 water inlet end of valve body
Overflow mechanism is equipped in overflow pipe 5.
Preferably, as shown in Fig. 2, the overflow mechanism be set to overflow pipe 5 lower end, including upper annular stop backstop 6 and
Lower annular stop backstop 7 is equipped with sealing plate 8, sealing plate 8 and upper annular with lower annular stop backstop 7 in upper annular stop backstop 6
Holddown spring 9 is equipped between limit stops 6, the upper end of the overflow pipe 5 is equipped with opening.When fluid pressure is greater than compression in valve body
When spring is to the down force of sealing plate, sealing plate is moved up, and liquid flows into overflow pipe, plays the role of pressure release.
Preferably, the top of the upper annular stop backstop 6 is equipped with the kickboard 10 gone up and down with liquid level, is equipped in kickboard 10
Mark rod 11.Kickboard 10 can be as liquid level ramps up, when ministry upper end after the liquid in overflow pipe is more and more, mark rod
11 are pierced by from the upper end of overflow pipe 5, play suggesting effect to staff, hydraulic excessively high in warning valve, when kickboard 10 rises to
When the top of overflow pipe 5,10 pairs of kickboard openings, which play sealing function, overflow liquid will not from top.
Preferably, the upper surface of the kickboard 10 and the lower surface of sealing plate 8 are equipped with rubber coating 12.
Preferably, it is also connected with drain pipe 13 on the side wall of the overflow pipe 5, is threadedly coupled in the output end of drain pipe 13
There is sealing pipe cap 14.After staff observes that mark rod rises, sealing pipe cap 14 can be opened, drain decompression is carried out.
When the utility model is used, need to only observe the rising situation of kickboard 10, that is, can determine whether is pressure in valve
Over-voltage, and can easily carry out very much pressure discharge operations.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the technical solution that the protection scope of the utility model should be recorded with claim, the technical solution recorded including claim
The equivalents of middle technical characteristic are protection scope.Equivalent replacement i.e. within this range is improved, also in the utility model
Protection scope within.
