Abstract
A kind of multifunctional valve box gland applied to reciprocating pump middle outlet check valve, including, vacuum tank, the vacuum tank is installed on the top of the multifunctional valve box gland；Pressure stabilizing through-hole is opened up along multifunctional valve box gland central axes, flows into fluid in the vacuum tank by the pressure stabilizing through-hole.The present invention is by being arranged vacuum tank in multifunctional valve box gland, so that multifunctional valve box gland has voltage stabilizing function.To reduce reciprocating pump middle outlet check valve in discharge pressure pulsation and the pressure change under flow pulsation effect, vibration and the noise of Outlet check valves are reduced.And then it improves the service life of reciprocating pump and increases its stability.
Description
Technical field
The present invention relates to the configuration of reciprocating pump check valve and installations, more particularly to applied to reciprocating pump middle outlet check valve
Valve gland.
Background technique
The valve gland for being installed on Outlet check valves is reciprocating pump hydraulic-end critical component.But the valve of Outlet check valves
Case gland only has the function of bearing reciprocal pump discharge pressure load, without having voltage stabilizing function.When reciprocating pump conveying high-pressure stream
When body, in the case where discharge pressure pulsation is acted on flow pulsation, so that the flow direction of high-pressure fluid and speed generate variation.From
And the pressure at Outlet check valves is caused to change, cause vibration and noise.
Summary of the invention
The present invention solves the problems, such as that Outlet check valves vibrate big, high noise.
In order to achieve the above object, the invention provides the following technical scheme: multifunctional valve box gland, including, vacuum tank, institute
State the top that vacuum tank is installed on the valve gland；Pressure stabilizing through-hole is opened up along the valve gland central axes, makes fluid by institute
Pressure stabilizing through-hole is stated to flow into the vacuum tank.
Wherein, by-passing parts are fixedly connected in the pressure stabilizing through-hole, the by-passing parts open up multicomponent recirculation hole.
Wherein, the shunting through-hole is evenly arranged along the central axes of the by-passing parts.
Wherein, the outlet end of the outlet end for shunting through-hole and the pressure stabilizing through-hole maintains an equal level.
Wherein, the length for shunting through-hole is not more than the length of the pressure stabilizing through-hole.
Wherein, gauge manifold mouth is opened up in the sealing head of the vacuum tank.
Wherein, the valve gland opens up external screw thread.
The present invention is by being arranged vacuum tank in valve gland, so that valve gland has voltage stabilizing function.It is reciprocal to reduce
Pump middle outlet check valve discharge pressure pulsation with flow pulsation effect under pressure change, reduce the vibration of Outlet check valves with
And noise.And then it improves the service life of reciprocating pump and increases its stability.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is schematic structural view of the invention；
Specific embodiment
Below in conjunction with attached drawing of the invention, technical solution of the present invention is clearly and completely described, it is clear that institute
The embodiment of description is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this hair
The range of bright protection.
According to Fig. 1, multifunctional valve box gland 1 is fixedly connected by welding vacuum tank 2 on its top.Along clack box pressure
The central axes of lid 1 open up pressure stabilizing through-hole 3.By-passing parts 4 are set in pressure stabilizing through-hole 3.The outer wall and pressure stabilizing through-hole of by-passing parts 4
3 inner wall is bonded to form integral structure.By-passing parts 4 set multicomponent recirculation hole 5 along its central axes external-open, shunt the straight of through-hole 5
Diameter is less than the diameter of pressure stabilizing through-hole 3.Fluid passes sequentially through pressure stabilizing and leads to 3 holes, shunts through-hole 5, enters in vacuum tank 2.It is stored in
Fluid in vacuum tank 2 improves the sealing performance of valve gland 1 so that vacuum tank 2 has the characteristic of high pressure sealing.Pass through
By-passing parts 4 are set, reduces the length of pressure stabilizing through-hole 3, and then reduce linear loss, reduces vibration and noise.Again by more
The setting of component recirculation hole 5, area of passage increase, and flow velocity reduces, and play the role of distributing pressure difference, reduce that pressure difference is excessive causes
The noise of mouth check valve and vibration.But when fluid enters vacuum tank 2, vacuum tank 2 alleviates discharge pressure pulsation and flow pulsation
It influences, further reduced the vibration for reducing Outlet check valves and noise.
In an alternative embodiment, it shunts through-hole 5 to be evenly arranged outside the central axes of by-passing parts 4, is conducive to fluid
Smooth flow is reduced 4 end face of by-passing parts and is generated vibration and noise due to fluid impact.
In an alternative embodiment, the outlet end of the outlet end and pressure stabilizing through-hole 3 that shunt through-hole 5 maintains an equal level, convenient for system
Make, reduces production cost.
In an alternative embodiment, the length for shunting through-hole 5 is less than or equal to the length of pressure stabilizing through-hole 3, more sharp
Vibration equipment and noise caused by alleviating pressure difference and changing.
In an alternative embodiment, the one end of vacuum tank 2 far from valve gland 1 is end socket, in the end socket of vacuum tank
Portion opens up gauge manifold mouth 6, and gauge manifold mouth 6 allows to monitoring pressure in real time and pressure arteries and veins for installing pressure gauge
Dynamic numerical value.
In an alternative embodiment, valve gland 1 opens up external connection screw 7, is easily installed and dismantles, and is conducive to dimension
It repairs.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
