Abstract
The invention relates to a hinged-door check valve which is characterized by comprising a valve body. A fluid inlet and a fluid outlet are arranged on two sides of the valve body respectively, control part is arranged on the valve body, and a valve bonnet is arranged on the upper portion of the control part and is fixed on the valve body through a fixing part. The control part comprises a double-valve seat, a torsional spring, a central shaft and a support are arranged on the double-valve seat, the fixing part is composed of a bolt and a nut or a fastener and a fastener groove, and the double-valve seat is a metal seal with an inclined surface. The hinged-door check valve has the advantages that the check valve is simple structure, small in size, convenient to mount and maintain and low in cost; the double-valve seat is the metal seal with the inclined surface, and the check valve can be used in most media and high-and-low temperature environment, and is wide in application range.
Description
Technical field
The present invention relates to a kind of one-way valve, relate in particular to a kind of door-opening type one-way valve, can guarantee that medium can only one-way flow in valve under especially being used in the Process of Oil Well Drilling, can not bring one-way valve in the circulatory system into because of the pressure in the pit shaft.
Background technique
One-way valve is important valve constituent element in the petroleum industry, principle is that the circulation swallow is asked for direction and flows and open valve, and the power of having ruined can make valve closing, thereby realizes the one-way flow of fluid.The most frequently used one-way valve structure has spring rise-fall type and Single disc spin-up open and close type in the industry now.The shortcoming of spring rise-fall type has fluid to promote piston stroking upward, is easy to generate vibration and noise, and can there be restriction in piston after lifting, and causes Sealing to wash away damage.Single disc spin-up open and close type characteristics are that the flashboard activity space is big, cause the valve volume excessive, and Single disc are overweight, and valve can only horizontal positioned.Above-mentioned two kinds of one-way valves in various degree all have a shortcoming, therefore, a kind of one-way valve of exigence solves above-mentioned technical problem.
Summary of the invention
The present invention provides a kind of simple in structure, easy to operate, reliable, lower-cost a kind of door-opening type one-way valve of sealing just at the technical problem that exists in the prior art.
To achieve these goals, technological scheme of the present invention is as follows, a kind of door-opening type one-way valve, it is characterized in that, described one-way valve comprises valve body, and the both sides of valve body are respectively arranged with fluid input and fluid output, and described valve body is provided with controlling component, the top of described controlling component is provided with valve gap, is fixed on the valve body by fixed component.
As a kind of improvement of the present invention, described controlling component comprises the bivalve seat, is arranged on torsion spring, central shaft and support on the bivalve seat.
As a kind of improvement of the present invention, described fixed component is set to the mode that mode that bolt, nut fix or buckle, draw-in groove fix.
As a kind of improvement of the present invention, described bivalve seat is set to have the metal sealing on inclined-plane.
As a kind of improvement of the present invention, the inclined-plane of described bivalve seat and the inclination angle of horizontal plane are 30 °---90 °.
As a kind of improvement of the present invention, the inclined-plane of described bivalve seat and the inclination angle of horizontal plane are preferably 45 °---and 60 °.
With respect to prior art, advantage of the present invention is as follows, and 1) this one-way valve is simple in structure, volume is small and exquisite, and installation and maintenance are convenient, cost is lower; 2) the bivalve seat is designed to the metal sealing on inclined-plane, and therefore, this valve can be used in most medium and the high and low temperature environment, and Applicable scope is wider.
Description of drawings
Fig. 1 is overall structure schematic representation of the present invention;
Fig. 2 is the controlling component enlarged view;
Among the figure: 1, valve body, 2, the bivalve seat, 3, valve gap, 4, torsion spring, 5, central shaft, 6, support, 7, bolt, 8, nut, 9, fluid input, 10, fluid output.
Embodiment
In order to deepen the understanding of the present invention and understanding, below in conjunction with the drawings and specific embodiments the present invention is made further instructions and introduces.
Embodiment 1:
Referring to Fig. 1, a kind of door-opening type one-way valve, described one-way valve comprises valve body 1, the both sides of valve body are respectively arranged with fluid input 9 and fluid output 10, described valve body 1 is provided with controlling component, and the top of described controlling component is provided with valve gap 3, is fixed on the valve body 1 by fixed component.This one-way valve is simple in structure, volume is small and exquisite, and installation and maintenance are convenient, cost is lower.
Embodiment 2:
As a kind of improvement of the present invention, described controlling component comprises bivalve seat 2, is arranged on torsion spring 4, central shaft 5 and support 6 on the bivalve seat 2.All the other structures and advantage and embodiment 1 are identical.
Embodiment 3:
As a kind of improvement of the present invention, described fixed component is set to the mode that mode that bolt 7, nut 8 fix or buckle, draw-in groove fix.All the other structures and advantage and embodiment 1 are identical.
Embodiment 4:
As a kind of improvement of the present invention, described bivalve seat 2 is set to have the metal sealing on inclined-plane.All the other structures and advantage and embodiment 1 are identical.
Embodiment 5:
As a kind of improvement of the present invention, the inclined-plane of described bivalve seat 2 and the inclination angle of horizontal plane are 30 °-90 °.The inclination angle is preferably 45 °-60 °.All the other structures and advantage and embodiment 1 are identical.
The present invention can also be combined to form new mode of execution with at least one and the embodiment 1 in embodiment 2,3,4, the 5 described technical characteristicss.
Working principle:
Fluid flows into through fluid input 9 before the proper functioning, and when pressure during greater than the spring force of torsion spring 4, double-flashboard Unscrew, the fluid valve opening of flowing through flows out from fluid output 10.Too small or when fluid output 10 pressure were higher than fluid input 9, double-flashboard was closed under the active force of torsion spring 4 when hydrodynamic pressure, stop fluid to reflux.Because the bivalve seat board is designed to the metal sealing on inclined-plane, so this valve can be used under the environment of most of medium and high low temperature.
Need to prove that above-described embodiment only is preferred embodiment of the present invention; be not used for limiting protection scope of the present invention; being equal to replacement or substituting of having done on the basis of the above all belongs to protection scope of the present invention, and protection scope of the present invention is as the criterion with claims.
