Abstract
The invention discloses a two-way valve which comprises a valve body. A joint is installed on the valve body, and is internally provided with a valve rod; a fluid inlet and a fluid outlet are respectively arranged on the two sides of the valve body; the valve body is internally provided with an interface which is communicated with the fluid inlet and the fluid outlet and is provided with a valve cover driven by the valve rod to open or close the interface; when the interface is closed, the outer side wall of the valve core is fit with the inner side wall of the interface so as to close the interface, and thus fluid can not flow; and the valve body is internally provided with a fit surface which is fit with the upper end surface of the valve cover so as to prevent the fluid from applying force to the upper end surface of the valve cover, thus, the pressure of the valve rod as well as the pressure of a spring sleeved on the valve rod is reduced, the debugging force of the valve is lowered, the shutoff pressure difference of the valve is increased; and further the flow rate of the valve increases.
Description
Technical field
The present invention relates to a kind of Twoway valves, be used for air-conditioning, HVAC, energy-conservation liquid control system.
Background technique
Valve is the controlling component in the fluid delivery system, has the functions such as cut-off, adjusting, water conservancy diversion, counterflow-preventing, voltage stabilizing, shunting and overflow pressure relief, plays very important effect in transporting system.The working principle of valve is to promote valve gap by valve rod to move, and valve gap is opened or closed the interface that connects the fluid in-and-out pipe, is socketed with spring part on the valve rod valve rod is resetted, thereby realize that valve is normally closed or often open.The topmost technological difficulties of valve are how to guarantee the sealing of valve gap and jointing, at present common sealing configuration is end face seal on the market, namely pass through the end face shutoff interface of valve gap, it is too small that but this structure can be born pressure, fluid is the movement direction of valve gap to the force direction of valve gap, when the pressure of fluid input end increases, with the pressure reduction increase of fluid output terminal, just easily make valve gap and jointing the slit occur, cause leakage.
Summary of the invention
For addressing the above problem, the invention provides a kind of simple in structure, the Twoway valves of good airproof performance.
The present invention is that the technological scheme that its problem of solution adopts is:
A kind of Twoway valves comprises valve body, and joint is installed on the valve body, and valve rod is installed in the joint; The valve body both sides are respectively arranged with fluid input and fluid output, be provided with the interface of communication of fluid entrance and fluid output in the valve body, described jointing is provided with by valve rod and drives to open or the valve gap of down interface, when described interface is closed, the outer side wall of described valve gap is fitted on the madial wall of interface, and fluid can't be flowed.Be provided with in the valve body with the upper-end surface of valve gap and fit so that fluid can't apply to the upper-end surface of valve gap the faying surface of active force, thereby reduce valve rod and the pressure that is enclosed within the spring on the valve rod, reduce the debugging dynamics of valve, increase the shutoff pressure reduction of valve, and then increase the flow of valve.
Preferably, described faying surface is the bottom end of joint, be equipped with on this bottom end can and the valve gap upper-end surface fit to prevent that fluid from entering the sealing gasket in the slit between joint and the valve gap.Further, the cross section of described sealing gasket is T-shaped, and the one side is connected in the groove that is located at the joint bottom; Its another side is connected on the boss that is located at valve interior wall, so not only so that fluid can't enter the slit between joint and the valve gap, also so that fluid can not go out from the slot leakage between joint and valve interior wall.
Preferably, the O type circle of fitting to prevent the fluid leakage with the valve gap outer side wall is installed on the madial wall of described interface.
Preferably, described valve gap is cylindrical, when the pressure of fluid is applied on the side of valve gap, only can produce the active force perpendicular to the valve gap axle center, and this active force can be to the axial motion generation effect of valve gap, thereby can not increase the pressure of valve rod and spring.
The invention has the beneficial effects as follows: the shutoff pressure reduction that 1, has increased valve; 2, increased the fluid flow of valve; 3, reduce the pressure of spring, reduced valve debugging dynamics; 4, simple in structure, strengthened the sealing of valve.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is internal structure schematic diagram of the present invention.
Embodiment
A kind of Twoway valves as shown in Figure 1 comprises valve body 1, and joint 2 is installed on the valve body 1, valve rod 3 is installed in the joint 2, be socketed with the spring that valve rod 3 is resetted by elastic force outside the valve rod 3, so just can realize that after removing external force, valve is in Chang Kai or normally closed state.Valve body 1 both sides are respectively arranged with fluid input 4 and fluid output 5, are provided with the interface 6 of communication of fluid entrance 4 and fluid output 5 in the valve body 1, and described interface 6 places are provided with by valve rod 3 and drive to open or the valve gap 7 of down interface 6.
When described interface 6 was closed, the outer side wall of described valve gap 7 was fitted on the madial wall of interface 6, and fluid can't be flowed.Be provided with in the valve body 1 with the upper-end surface of valve gap 7 and fit so that fluid can't apply to the upper-end surface of valve gap 7 faying surface of active force, thereby reduce valve rod 3 and the pressure that is enclosed within the spring on the valve rod 3, reduce the debugging dynamics of valve, increase the shutoff pressure reduction of valve, turn-off pressure reduction and be increased to 5bar by present 2bar, therefore, interface 6 can be arranged to larger bore, increasing the flow of fluid, the flow of Twoway valves of the present invention wants many more than 60% with respect to the valve of existing same specification on the market.
Described faying surface is the bottom end of joint 2, described joint 2 bottoms be equipped with can and valve gap 7 upper-end surfaces fit to prevent that fluid from entering the sealing gasket 8 in the slit between joint 2 and the valve gap 7.Further, the cross section of described sealing gasket 8 is T-shaped, and the one side is connected in the groove 9 that is located at joint 2 bottoms; Its another side is connected on the boss 10 that is located at valve body 1 inwall, so not only so that fluid can't enter the slit between joint 2 and the valve gap 7, also so that fluid can not go out from the slot leakage between joint 2 and valve body 1 inwall.
The O type circle 11 of fitting to prevent the fluid leakage with valve gap 7 outer side walls is installed on the madial wall of described interface 6.Described valve gap 7 is cylindrical, when the pressure of fluid is applied on the side of valve gap 7, only can produce the active force perpendicular to valve gap 7 axle center, and this active force can be to the axial motion generation effect of valve gap 7, thereby can not increase the pressure of valve rod and spring.
Above specification is described, only is principle of the present invention and embodiment, everyly carries out any simple modification and variation according to essence of the present invention, all belongs within the protection domain of the presently claimed invention.
