Abstract
The invention discloses a kind of check valves, it includes valve body, is installed on the intracorporal valve block that can unidirectionally bend of valve, valve block include with the close-connected air inlet orifice plate of valve body inner sidewall, be connected to the rubber ring that can unidirectionally bend on air inlet orifice plate, when no gas enters valve body, rubber ring is fitted closely with valve body, when gas enters from valve body air inlet, gap is formed between rubber ring bending and valve body.Rubber ring is closely connect by the present invention with air inlet orifice plate, and when closing is required, air inlet orifice plate can improve the rebound velocity of rubber ring, guarantees that dust does not return to air inlet, damages the various valves on admission line.
Description
Technical field
The present invention relates to Pneumatic ash conveying equipment, in particular to a kind of check valve.
Background technique
There are problems for existing pneumatic ash transmitting system check valve, such as: air outlet parts can generate its grey mixture, existing
Some valve blocks, in the presence of that cannot spring back sealing in time, lead to have part dust can be back to air inlet, dust after mouth is opened in deformation
The various valves on admission line can be damaged.
Summary of the invention
The object of the present invention is to provide one kind when closing is required, and air inlet orifice plate can improve the rebound velocity of rubber ring, protects
Card dust do not return to air inlet, damage admission line on various valves check valve.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of check valve comprising valve body is installed on institute
State the intracorporal valve block that can unidirectionally bend of valve, the valve block include with the close-connected air inlet orifice plate of valve body inner sidewall, be connected to
The rubber ring that can unidirectionally bend on the air inlet orifice plate, when no gas enters valve body, the rubber ring and the valve body are close
Fitting forms gap between the rubber ring bending and the valve body when gas enters from valve body air inlet.
Optimization, the rubber ring is mutually fixedly connected with the air inlet orifice plate by bolt assembly.
Optimization, the valve body is made of two symmetrical shells, the axis of the mating surface of two shells and the valve body
Line is perpendicular.
Optimization, the inner cavity of the valve body is made of main chamber and the symmetrical secondary chamber that main chamber both ends are arranged in, described
The side wall rounding off of main chamber and the secondary chamber.
Optimization, card slot is offered in the middle part of the intracavity sidewall of valve body, the air inlet board is set in the card slot.
Due to the above technical solutions, the present invention has the following advantages over the prior art: the present invention is by rubber ring
It is closely connect with air inlet orifice plate, when closing is required, air inlet orifice plate can improve the rebound velocity of rubber ring, guarantee that dust will not return
Various valves onto air inlet, damage admission line.
Detailed description of the invention
Accompanying drawing 1 is the structural representation of the present invention.
In the figures above: 1, valve body;2, valve block;3, air inlet orifice plate;4, rubber ring;5, bolt assembly;6, shell;7, main
Chamber;8, secondary chamber;9, baffle;10, bolt;11, nut.
Specific embodiment
The invention will be further described for embodiment shown in reference to the accompanying drawing.
As shown in Figure 1, check valve includes valve body 1, the valve block 2 that can unidirectionally bend that is installed in the valve body 1, the valve
Piece 2 include with the close-connected air inlet orifice plate 3 of 1 inner sidewall of valve body, be connected to the rubber that can unidirectionally bend on the air inlet orifice plate 3
Circle 4, when no gas enters valve body 1, the rubber ring 4 is fitted closely with the valve body 1, when gas from 1 air inlet of valve body into
It is fashionable, gap is formed between the bending of rubber ring 4 and the valve body 1.The rubber ring 4 and the air inlet orifice plate 3 pass through spiral shell
5 phase of bolt assembly is fixedly connected.The valve body 1 is made of two symmetrical shells 6, the mating surface of two shells 6 and the valve
The axis perpendicular of body 1.The inner cavity of the valve body 1 is made of main chamber 7 and the symmetrical secondary chamber 8 that 7 both ends of main chamber are arranged in,
The side wall rounding off of main chamber 7 and the secondary chamber 8.Card slot, the air inlet are offered in the middle part of the intracavity sidewall of valve body
Hole board 3 is set in the card slot.
The bolt assembly 5 includes bolt 10, nut 11 and baffle 9, and the baffle 9 is by baffle and is connected to described
It around baffle and is substantially in pyramidal retaining ring, the retaining ring can prevent 4 transition of rubber ring from bending.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
