Description
Technical field
The utility model carves type double-flashboard gate valve more particularly to a kind of durable formula.
Background technique
Gate valve is an opening and closing element flashboard, and the direction of motion and flow direction of flashboard are perpendicular, gate valve can only make standard-sized sheet and
Quan Guan cannot make adjustments and throttle.Gate valve is sealed by valve seat and rams contact, and usual sealing surface can deposited metal material
To increase wearability, such as built-up welding 1Cr13, STL6, stainless steel.Flashboard has rigid flashboard and flexible disc, not according to flashboard
Together, gate valve is divided into rigid gate valve and resilient gate valve.
Friction up and down when existing gate valve is due to opening and closing, there is a problem that it is easy to wear, so result in long-time service
Under gate valve be easy to appear leak and close not tight problem, affect use.
Utility model content
The technical problem to be solved by the present invention is to provide one kind can reduce the durable of abrasion caused by friction up and down
Formula carves type double-flashboard gate valve.
To solve the above problems, the utility model adopts the following technical solution:
A kind of durable formula carves type double-flashboard gate valve, includes valve body, and the V-shaped valve seat being installed in the channel of valve body, and
The flashboard being installed in V-shaped valve seat, is equipped with V-seal face between the V-shaped valve seat and flashboard, the flashboard includes and V-type
The left connecting rod and right connecting rod of sealing surface rotation connection, the flashboard top are equipped with the valve rod being hinged with left connecting rod and right connecting rod, institute
It states and is equipped with tension spring below left connecting rod and right connecting rod, the tension spring is connected on V-seal face, and valve deck is connected on the valve rod, described
Valve body is equipped at intervals with bowl-type diaphragm with valve deck, and bellows is cased with outside the valve rod.
Preferably, the top of the bellows is welded with bowl-type diaphragm, bottom and valve rod are mutually welded.
Preferably, the V-seal face is made of a left plate body and a right panel body, between the left plate body and right panel body
Equipped with gap.
Preferably, being all equipped with a rotation seat matched with left connecting rod and right connecting rod on the left plate body and right panel body.
Preferably, it is concentric setting that the left connecting rod and right connecting rod, which are located at the hinged part on valve rod,.
The utility model has the following beneficial effects: cooperate the design of tension spring by left connecting rod and right connecting rod, so that flashboard can be with
Above and below realizing without frictional movement, conducive to the abrasion reduced between flashboard and V-seal face, meanwhile, bellows and bowl-type diaphragm
Combination Design, can reduce valve rod while reducing flashboard and moving up and down abrasion and encounter filler generation when moving up and down
Abrasion, further extends service life.
Detailed description of the invention
Fig. 1 is the overall structure diagram that a kind of durable formula of the utility model carves type double-flashboard gate valve；
Fig. 2 is the portion the A enlarged drawing that a kind of durable formula of the utility model carves type double-flashboard gate valve.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, so that the utility model technology
Scheme is more readily understood and grasps.
As shown in Figs. 1-2, a kind of durable formula carves 3 gate valve of type double disc, includes valve body 1, and be installed on the channel of valve body 1
Interior V-shaped valve seat 2, and the flashboard 3 being installed in V-shaped valve seat 2 are equipped with V-seal face 4 between the V-shaped valve seat 2 and flashboard 3,
The flashboard 3 includes the left connecting rod 31 being rotatablely connected with V-seal face 4 and right connecting rod 32, is equipped with and a left side above the flashboard 3
The valve rod 5 that connecting rod 31 and right connecting rod 32 are hinged is equipped with tension spring 33 below the left connecting rod 31 and right connecting rod 32, and the tension spring 33 connects
In on V-seal face 4, being connected to valve deck 6 on the valve rod 5, the valve body 1 and valve deck 6 are equipped at intervals with bowl-type diaphragm 7, described
Bellows 8 is cased with outside valve rod 5, top and the welding of bowl-type diaphragm 7, bottom and 5 phase of valve rod of the bellows 8 are welded, the V-type
Sealing surface 4 is made of a left plate body 41 and a right panel body 42, and gap, the left side are equipped between the left plate body 41 and right panel body 42
A rotation seat 43 matched with left connecting rod 31 and right connecting rod 32,31 He of left connecting rod are all equipped on plate body 41 and right panel body 42
It is concentric setting that right connecting rod 32, which is located at the hinged part on valve rod 5,.
Principle explanation:
Since bellows 8 can obstruct the contact of valve rod 5 with airtight and watertight padding in valve body 1, and it will not influence the normal of valve rod 5
It uses, thus reduce the abrasion of valve rod 5, meanwhile, the special designing of flashboard 3 is close by left connecting rod 31 and right connecting rod 32 and V-type
The hinge of cover 4 designs, so that flashboard 3 when moving up, is moved via the switching of left connecting rod 31 and right connecting rod 32,
Avoid abrasion caused by directly sliding.
The utility model has the following beneficial effects: cooperate the design of tension spring by left connecting rod and right connecting rod, so that flashboard can be with
Above and below realizing without frictional movement, conducive to the abrasion reduced between flashboard and V-seal face, meanwhile, bellows and bowl-type diaphragm
Combination Design, can reduce valve rod while reducing flashboard and moving up and down abrasion and encounter filler generation when moving up and down
Abrasion, further extends service life.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
