Description
Technical field
The utility model relates to casting field, in particular, relates to a kind of gate valve cover.
Background technique
Gate valve is a kind of modal keying valve, utilizes flashboard to connect or blocks the medium in pipeline.It does not allow as use of damming, and flashboard trace should be avoided in using to open, and the erosion because of swiftly flowing medium can accelerate the damage of sealing surface.
Valve gap is one of main parts size of composition gate valve, valve gap is above valve body, the through hole that one end of valve rod is passed down through on valve gap is connected with flap, the other end of valve rod is upwards connected with handwheel, corresponding to a Stem Mut that the valve rod in valve gap through hole spins, it is Spielpassung between Stem Mut and valve gap, in operation, owing to producing relative movement between Stem Mut and valve gap, therefore valve gap and Stem Mut very easily wear and tear, reduce working life of gate valve, simultaneously large, the working costs effort of valve operation moment of torsion.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of gate valve cover.
For achieving the above object, the utility model provides following technological scheme: a kind of gate valve cover, comprise bonnet flange, bonnet flange is provided with the through hole of interspersed valve rod, support is connected with in this bonnet flange, the other end of the relative valve rod flange of described support is provided with Stem Mut, described Stem Mut is provided with shoe cream room, the outer side wall of this Stem Mut is provided with the one-way valve be connected with this shoe cream room, described one-way valve comprises oil inlet hole, the floating ball of this oil inlet hole can be blocked, prop up the elastic component of this floating ball, the madial wall of Stem Mut is provided with multiple oil outlet be connected with this shoe cream room, adsorbate is filled with in shoe cream room.
By adopting technique scheme, by the shoe cream room on Stem Mut, when valve rod is rotated by handwheel thereon time, rotation can be made more laborsaving, by one-way valve, wheel lubricating oil can be added at oil inlet hole place, then by the adsorbate in shoe cream room, can be good at the effect reaching oil storage, prevent inner wheel lubricating oil from having leaked unwanted time, lubrication effect is more lasting; And when valve rod and Stem Mut carry out in relative rotation, can generate heat, adsorbate in shoe cream room can expand with heat and contract with cold, when heating, the deposit that can be lubricant oil is therein flowed out automatically by oil outlet, reaches lubrication when using valve rod, effect not fuel-displaced when not using valve rod, more further save the use of lubricant oil, efficiency and effect reach optimization.
The utility model is set to further: described adsorbate is malthoid or sponge.
The utility model is set to further: the hole wall of described through hole is provided with the oil storage felt portion caved inward.
The utility model is set to further: described oil inlet hole is the large outer young sphere hole of internal orifice, and inner ring surface and the floating ball of this internal orifice are fitted mutually.
Compared with prior art, the utility model has following advantage: by the malthoid that arranges in shoe cream room or sponge, storage time and the stability of lubricant oil in shoe cream room of lubricant oil can be extended, and pass through one-way valve, can be unidirectional and the past oil inlet hole do not revealed adds lubricant oil, and by oil outlet, realize the effect of automatic oil outlet, make become very laborsaving when rotation valve rod and reduce wear.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model gate valve cover;
Fig. 2 is the formal figure of the utility model gate valve cover;
Fig. 3 is the A-A view of Fig. 2.
In figure: 1, bonnet flange; 2, through hole; 21, felt portion is stored up; 3, support; 4, Stem Mut; 41, oil inlet hole; 42, oil outlet; 5, floating ball; 6, spring; 7, adsorbate.
Embodiment
Easily fill compact type outlet passage valve body embodiment referring to figs. 1 through Fig. 3 to the utility model to be described further.
The present embodiment comprises bonnet flange 1, bonnet flange 1 is provided with the through hole 2 of interspersed valve rod, support 3 is connected with in this bonnet flange 1, the other end of the relative valve rod flange of described support 3 is provided with Stem Mut 4, described Stem Mut 4 is provided with shoe cream room, the outer side wall of this Stem Mut 4 is provided with the one-way valve be connected with this shoe cream room, described one-way valve comprises oil inlet hole 41, the floating ball 5 of this oil inlet hole 41 can be blocked, described oil inlet hole 41 is the large outer young sphere hole of internal orifice, inner ring surface and the floating ball 5 of this internal orifice are fitted mutually, prop up the elastic component of this floating ball 5, the madial wall of Stem Mut 4 is provided with multiple oil outlet 42 be connected with this shoe cream room, adsorbate 7 is filled with in shoe cream room, described adsorbate 7 is malthoid or sponge, the hole wall of described through hole 2 is provided with the oil storage felt portion caved inward.
According to said structure and accompanying drawing, when needs inject lubricant oil to shoe cream room time, inwardly pressing floating ball 5, think that oil inlet hole 41 injects lubricant oil, the adsorbate 7 be arranged in shoe cream room will be filled lubricant oil, bleed off floating ball 5 afterwards, and oil inlet hole 41 is blocked under the effect of spring 6 by automatically.
In time rotating handwheel band ovable valve stem and rotate, frictional heat will be there is between valve rod and Stem Mut 4, adsorbate 7 will expanded by heating, the lubricant oil of absorption is extruded from oil outlet 42 automatically, reaches the effect of lubrication valve rod and Stem Mut 4, this mode, prevent inner wheel lubricating oil from having leaked unwanted time, lubrication effect is more lasting, reaches the effect of saving lubricant oil, and realizes the function of automation lubricating oil filling.
Further, by being arranged on the storage felt portion 21 in through hole 2, can place felt within it, when valve rod is mobile in through hole 2 time, and the sealability between through hole 2 will strengthen greatly.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
