Abstract

The utility model discloses a water valve. A small U-shaped pipe is added in a pipe body, and a push rod is arranged in the pipe and passes through the U-shaped pipe and a fastening component. One end of the push rod is exposed outside the pipe body. The upper part of the push rod is provided with a return spring, and the lower part of the push rod is provided with a water outlet. The side of the pipe body has the exposed part of the push rod and is provided with a handle with a cam. A water source can be opened or closed by pushing or pulling the handle. The water valve adopts the function of the water pressure and the spring to seal the water source, and thus, the abrasion degree of a pad is lower than a common water tap. Thus, the utility model has reliable performance and high durability. The utility model is suitable for civil use and the use of the public place.

Description

Push-pull water valve

The utility model is a kind of valve, is a kind of plug-type water valve specifically.

General water tap mainly adopts external force to suppress the sealing method now, twists screw rod by hand and makes the water seal pad cover the hole of the tap water of certain pressure by force, and the initial use of this water tap is all right, and chien shih water packing wearing and tearing often or breakage cause leaks.

The purpose of this utility model is to provide a kind of closed performance reliable, durable plug-type water valve.

The utility model is to realize like this; Adorn a bit of U-shaped pipe at one section pipe in this, U-shaped tube and tube body one end is fixedly connected, adorns a push rod in the pipe, and an end of push rod passes the U-shaped pipe and exposes body with fastening piece that body links; Be with spring in the U-shaped pipe on push rod, its both ends of the spring has seal ring, and the other end of push rod has a cover seal arrangement at least, and they are the boss by sealing supporting spring, liner and the inner tube wall of fastening piece connection; The water outlet that communicates with body is arranged under the push rod, and handle bracket exposes an end at push rod and links to each other with body, and it has the handle of cam to link to each other by an axle and an end.The pulling handle, the cam roof pressure push rod of handle makes it mobile inwards, and liner leaves boss inwards like this, and water just flows to body, flows out from water outlet; When the pushing handle return, cam is the roof pressure push rod no longer, seals the water source under the acting in conjunction of return spring and hydraulic pressure.

When this water valve was two cover seal arrangements, its two push rod linked to each other.

Advantage of the present utility model is, its sealing water source is by the pressure of water, the wearing and tearing of key component pad have so just been alleviated, so this water valve is durable, water-outlet quantity can be according to the adjustable angle of plate active handle, because cam and push rod have centre distance poor, handle can any angle in stroke be located naturally, and is easy to use.

Fig. 2 is the utility model embodiment schematic representation

The utility model is described in further detail below in conjunction with accompanying drawing.

Body (1) is cast together with U type pipe box as seen from Figure 1, in pipe (1), push rod (3) is arranged, its end passes U type pipe (4) and exposes body with the push rod turnbuckle (7) that links to each other with pipe (1), in going up U type pipe, push rod (3) is with return spring (5), both ends of the spring is low pressure seal circle (13), and the other end of push rod (3) seals the water source jointly with the convex platform (12) of screw (10) fixing seal supporting spring (2) and gasket seal (11), gasket seal and inner tube wall.The water outlet (14) that not communicates with pipe is arranged under the push rod (3), handle bracket (15) exposes a side at push rod and links to each other with body, support links to each other with the handle (9) of an end strap cam (8) by axle (16), and (17) are handle stop rest, and (6) are the push rod spring rest.Fig. 1 is the user mode that pulls handle, cam (8) roof pressure push rod (3) makes it mobile inwards, make gasket seal (11) leave the boss (12) of inner tube wall, water enters body under pressure and flows out from water outlet (14), cam and push rod have centre distance poor (22), and any angle of handle in stroke located naturally.As long as push away a lower handle (11) when closing, water valve just can cut out the water source under return spring and hydraulic pressure acting in conjunction.

Fig. 2 is two-stage sealing water valve, connect the one-level locking device at water valve shown in Figure 1 again by water source one end, (18) be the one-level closure, inwall has screw thread, (19) be push rod road sheet, the push rod of one-level closure (20) links to each other with the push rod (3) of secondary seal body, and (21), (12) are respectively the boss of one-level, secondary seal.Dismantled and assembled between one-level sealing and the secondary seal, the two-stage water valve uses safety better simultaneously, can directly change, repair under the situation of not cutting off the water supply when second level valve damages.

Claims

1, a kind of plug-type water valve, it is characterized in that it is that one section body (1) is arranged, a bit of U type pipe (4) is arranged in it, U type pipe (4) is fixedlyed connected with an end of body (1), adorn a push rod (3) in the pipe (1), one end of push rod (3) passes U type pipe (4) and exposes body with fastening piece (7) that body links, in going up U type pipe, push rod (3) is with spring (5), both ends of the spring has seal ring (13), the other end of push rod (3) has at least a cover sealing to close device, and they are the sealing supporting springs (2) that link by fastening piece (10), the boss (12) of gasket seal (11) and inner tube wall; The water outlet (14) that communicates with body is arranged under the push rod (3), and handle bracket (15) exposes a side at push rod and links to each other with body, and it has the handle (9) of cam (8) to link to each other by axle (16) with an end.

2, water valve according to claim 1 is characterized in that, can also pacify a cover seal arrangement again at water intake one end of valve, and its push rod (20) links to each other with push rod (3).
