Abstract
The utility model provides a liquid-control valve which is arranged in the water return pipeline of the heating system of a normal-pressure water-heating boiler and has simple structure and low cost and can avoid the leakage phenomenon at the bottom cover of the liquid-control valve. The utility model is composed of a valve body, a valve cover body, a liquid control port, a valve seat body, a piston spring, a valve rod, a valve clack, a water outlet and a water inlet, and is characterized in that the valve seat body is arranged below the valve cover body, the lower end of the valve seat body is connected and matched with the middle wall of the valve body, and the piston is arranged in the valve cover body. The utility model is suitable for controlling the pipeline of the hot-water circulating system.
Description
The utility model relates to the hydraulic control valve of installing on a kind of normal-pressure hot-water boiler heating system water return pipeline.
In the prior art, general hydraulic control valve commonly used, as shown in Figure 2, end opening (9) is arranged at its valve body (7) bottom, and bottom (11) is with end opening (9) shutoff.Locking nut (12), spring (13), guide holder (10) are arranged below the flap (5).When the liquid of certain pressure when hydraulic control mouth (1) is imported, the elastic force that piston (17) overcomes spring (13) moves downward, and by threshold bar (15) flap (5) is opened valve opening (4), conducting between this moment water intake (14) and the water outlet (6).
The hydraulic control valve of this structure, its valve body (7) has (3) suitable for reading, end opening (9), valve opening (4) is an one with valve body (7), after machining intact (3) suitable for reading, for the sealing surface of processing valve opening (4) and the housing end face of end opening (9), need carry out secondary frock and processing.Thereby the manufacturing procedure complexity, particularly when end face between the end opening (9) of bottom (11) and housing (7) and bolt (8) damage, cause leakage easily, influence the normal use of hydraulic control valve.
The purpose of this utility model will provide a kind of manufacturing procedure simple exactly, and easily manufactured valve body bottom is that whole nothing is leaked hydraulic control valve.
The utility model is to realize like this, a kind of hydraulic control valve is made up of valve gap body, hydraulic control mouth, valve body, piston, spring, valve rod, flap, water intake, water outlet, it is characterized in that, below the valve gap body valve body is arranged, valve body lower end and valve body midfeather are connected, and piston is at the inner chamber of valve gap body.
The utility model is embodiment be described further in conjunction with the accompanying drawings.
Accompanying drawing 1: be the utility model hydraulic control valve cross-sectional view.
Accompanying drawing 2: be existing hydraulic control valve cross-sectional view.
As shown in Figure 1, valve gap body (13) and valve body (8) upper end is connected, and is pressed in the top of valve body (5) below the valve gap body (13), and the midfeather (11) of the lower end of valve body (5) and valve body (8) is connected.Flap (7) opens and closes the valve opening (9) of valve body (5), and piston (2) is contained in the valve gap body (13), and spring (3) is below piston (2), and its bottom is pressed in the cavity on valve body (5) top.Valve rod (4) upper end is connected with piston (2), and the lower end is connected with flap (7).Because the end seal face of the valve opening (9) on the valve body (5) is mach together when making valve body (5), and spring (3) is contained in below the piston (2), so valve body (8) cavity of resorption needn't designed openings, and cast integral body.Save bottom and connecting bolt.
When hydraulic control mouth (1) has been located the pressured fluid input, the elastic force that piston (2) directly overcomes spring (3) moves downward, and make flap (7) open valve opening (9) by valve rod (4), cross the mouth of a river (12), conducting between the water outlet (10) on this moment water intake (6), valve opening (9), the valve body (5).When hydraulic control mouth (1) locates not have pressured fluid when input, move upward at the elastic force lower piston of spring (3), and flap (7) is closed valve opening (9) by valve rod (4).
Through trial-production and actual the use, the utility model is simple in structure, and cost is low, reliable performance.
Claims (1)
- The utility model hydraulic control valve, form by valve body (8), valve gap body (13), hydraulic control mouth (1), valve body (5), piston (2), spring (3), valve rod (4), flap (7), water intake (6), water outlet (10), it is characterized in that, valve body (5) is arranged below the valve gap body (13), the midfeather (11) of valve body (5) lower end and valve body (8) is connected, and piston (2) is at the inner chamber of valve gap body (13).
