Abstract
A hydraulic pressure one-way control valve comprises a valve body and a valve seat mutually cooperating with each other. One end part of the valve body is formed into a protruding rod extending into the valve seat; the valve body is provided with a water passage for the entering of water while the valve seat is also provided with a water passage but for the exiting of water. The two passages are communicated with each other through a radial direction through-hole provided on the protruding rod. The protruding rod of the valve body is sleeved with a sealing and fastening component made from a rubber hose, and the component has the same diameter as the protruding valve and corresponds well to the hydraulic pressure. The elastic rubber hose is disposed at the rear end of the radial direction through-hole arranged on the protruding rod and is shorter than the front end in length. The front end of the protruding rod is provided with a tightly sealed component between the valve body and the valve seat; the rear end provided with a loosely sealed component between the water passage for the entering of water and the water passage for the exiting of water. Except the elastic rubber hose, the components of the valve of the utility model are all fixed ones cooperated in a sealed manner; arranged this way, higher and more reliable performances can be acquired and the service lifetime of the valve is expected to be prolonged as well.
Description
Technical field
The utility model relate to a kind of in, the low pressure liquid control valve, specifically be relevant with a kind of fluid pressure one-way control valve.
Background technique
Present home and abroad hydraulic pressure one-way control valve, its structural feature comprises valve A as shown in Figure 1, valve seat B, spool C, spring D and seal ring E, its working principle be the reducing joint mouthful that utilizes fluid passage with spool closely cooperate the sealing liquid passage, with pressure spring spool is applied pretightening force.When oppositely pressurizeing, utilize the pressure of liquid itself to promote spool sealing liquid passage, passage ends.During positive pressurization, the pressure pushing pressure spring of liquid promotes spool and opens fluid passage, channel connection.This class hydraulically-controlled one-way valve generally is applied to oils.When it is applied to aqueous medium, because the problem of spring material very easily produces the turbid inefficacy of one-way valve and the fault of oil hydraulic circuit of causing of rust.
Summary of the invention
The utility model purpose is to solve above problem, and a kind of fluid pressure one-way control valve is provided, and it is simple and reasonable, has high reliability and long-life, and is not fragile, durable in use, can reduce the rate of fault of oil hydraulic circuit.
A kind of fluid pressure one-way control valve, comprise the valve body and the valve seat that cooperatively interact, the terminal nose bar that forms of described valve body extend in the valve seat, valve body is provided with entry and crosses water channel, valve seat is provided with water outlet and crosses water channel, water channel is crossed in described entry and water outlet is crossed water channel by means of the connection of the radial direction through hole on the nose bar, and sheathed one elastic rubber pipe that adapts with its diameter and fluid pressure forms sealing and pretension parts on the nose bar of valve body, the rear end that described elastic rubber pipe is positioned at the nose bar radial direction through hole is shorter in length than front end length, and its front end forms the tightening seal of valve body and valve seat, and the rear end forms entry and crosses the pine that water channel and water outlet cross water channel and seal.
The front end of described nose bar forms the dentation fastening structure and the elastic rubber pipe front end forms drive fit.
Adopt technique scheme, hydraulically-controlled one-way valve of the present utility model has mainly adopted elastic rubber pipe, replaces O-ring seal and pressure spring in the conventional hydraulic one-way valve.What be characterized in utilizing elastic rubber pipe and spool closely cooperates the sealing liquid passage, with the elastic force of elastic rubber pipe spool is applied pretightening force.When oppositely pressurizeing, the pressure of liquid itself is applied to the outside of rubber pipe, and the compressing rubber pipe shrinks, the fluid passage on the sealing spool, and passage ends.During positive pressurization, the pressure of liquid is applied to the inner face of rubber pipe, and the expansion of compressing rubber pipe is opened the fluid passage on the spool, channel connection.The elastic caoutchouc pipe part had both played the pretension effect like this, sealed again.Its material is durable in use, and is not fragile.Thereby improved the reliability of one-way valve greatly, reduced the rate of fault of oil hydraulic circuit.
Description of drawings
Below with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model prior art structural representation;
Fig. 2 is the utility model valve body structure schematic representation;
Fig. 3 is the utility model valve seat construction schematic representation;
Fig. 4 is the utility model assembled state structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
Mode of execution of the present utility model shown in Fig. 2-4, a kind of fluid pressure one-way control valve, comprise the valve body 1 and the valve seat 2 that cooperatively interact, the terminal nose bar 11 that forms of described valve body extend in the valve seat, valve body is provided with entry and crosses water channel 12, valve seat 2 is provided with water outlet and crosses water channel 21, water channel 12 is crossed in described entry and water outlet is crossed water channel 21 by means of 111 connections of the radial direction through hole on the nose bar 11, and sheathed one elastic rubber pipe 3 that adapts with its diameter and fluid pressure forms sealing and pretension parts on the nose bar 11 of valve body 1, the rear end that described elastic rubber pipe 3 is positioned at the nose bar radial direction through hole is shorter in length than front end length, and its front end forms the tightening seal of valve body and valve seat, and the rear end forms entry and crosses the pine that water channel and water outlet cross water channel and seal.
In actual the use, the front end of described valve body nose bar 11 can form dentation fastening structure 112 and form drive fit to form more firm sealing configuration with elastic rubber pipe 3 front ends.
Hydraulically-controlled one-way valve of the present utility model has mainly adopted elastic rubber pipe, replaces O-ring seal and pressure spring in the conventional hydraulic one-way valve.That utilizes elastic rubber pipe and spool closely cooperates the sealing liquid passage, with the elastic force of elastic rubber pipe spool is applied pretightening force.When oppositely pressurizeing, the pressure of liquid itself is applied to the outside of rubber pipe, and the compressing rubber pipe shrinks, the fluid passage on the sealing spool, and passage ends.During positive pressurization, the pressure of liquid is applied to the inner face of rubber pipe, and the expansion of compressing rubber pipe is opened the fluid passage on the spool, channel connection.The elastic caoutchouc pipe part had both played the pretension effect like this, to seal.Its material is durable in use, and is not fragile.Improve the reliability of one-way valve greatly, reduced the rate of fault of oil hydraulic circuit.
The utility model is except that elastic rubber pipe, and remaining part all is fixed components and for being sealed and matched, to realize higher reliability and to have prolonged its working life greatly.
