The utility model discloses a gas control apparatus for a braking system of a truck. The gas control apparatus is connected with gas pipes in the braking system and is a one-way valve two ends of which are connected with gas pipes respectively. The apparatus comprises a valve body, a valve core (4) and a spring (3), wherein the valve body (4) and the spring (3) are arranged in the valve body respectively, the valve core (4) is fitted in the valve body in a sliding manner, the valve body comprises a first valve body (5) and a second valve body (7) on which are in threaded connection and provided with corrugated joints (1), and the first valve body (5) is internally provided with a first step through hole (2) and the second valve body (7) is internally provided with a second step through holes (8) respectively. With the structure, the gas pipes in the pipeline only need to be sleeved into the corrugated joints and clasped by hoops, therefore, the configuration process of arranging the one-way valve into the pipeline is very simple and fast.
Description
Technical field
The utility model relates to valve field, specifically is the gas control equipment that is used for the truck brake system of gas flow in a kind of pilot line.
Background technique
At present, brake system on the truck generally adopts aerodynamic brake, its principle is that air compressor produces the gas with pressure, depress and open air pressure valve by twitching pedal, and the flow direction by gas in the manually operated valve pilot line, respectively gas is given the wheel cylinder of each wheel, the wheel cylinder pneumatically is propped brake block then, and brake block friction brake dish makes wheel braking.But, there is following shortcoming in this brake device: because the gas flow in the pipeline is controlled by manually operated valve, in other words, will manually open manually operated valve when needing in the pipeline to ventilate body, manually close manually operated valve when not required again, this has increased the complexity of operation greatly; In addition, the assembling of manually operated valve extremely bother, time-consuming.
The model utility content
Technical problem to be solved in the utility model is, provides a kind of control that makes gas flow in the pipeline more simply to be used for the gas control equipment of truck brake system.
For solving the problems of the technologies described above, the gas control equipment that is used for the truck brake system that the utility model provides, it is connected with tracheae in the brake system, and this device is one-way valve, and its two ends are connected with tracheae respectively.
This device comprises valve body, spool and spring, described spool and spring all are positioned at valve body, spool is slidingly fitted in the valve body, described valve body comprises first valve body and second valve body that is threaded, all be shaped on the bamboo joint type joint on described first valve body and second valve body, first through hole that has step type in first valve body, second through hole that has step type in second valve body.
The threaded one end of described second valve body is connected in first valve body, and described spring is positioned at first through hole of first valve body; Described spool is divided into three sections, and first section pushes against with spring, and the spool intermediate section and second valve body are close to, the 3rd section second through hole that is positioned at second valve body.
The surface of contact of the described spool intermediate section and second valve body is an arc surface.
The 3rd section cross section of described spool is star.
The joint of described first valve body and second valve body also is provided with seal ring.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) owing to replaced manually operated valve of the prior art, accomplished control more easily, and structure is very simple, operates also simpler, convenient, fast the gas of one-way flow in the pipeline with one-way valve;
2) in addition, first valve body of one-way valve and the second valve body two ends respectively have the bamboo joint type joint, only the tracheae in the pipeline need be inserted in to hold tightly on the bamboo joint type joint and with anchor ear to get final product, and the assembly process in the pipeline of therefore one-way valve being packed into is very simple, quick.
Description of drawings
Accompanying drawing is the structural representation that the utility model is used for the gas control equipment of truck brake system.
Wherein: 1, bamboo joint type joint; 2, first through hole; 3, spring; 4, spool; 5, first valve body; 6, seal ring; 7, second valve body; 8, second through hole.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Be used for by the utility model shown in the drawings the truck brake system gas control equipment structural representation as can be known, it is connected with tracheae in the brake system, this device is one-way valve, its two ends are connected with tracheae respectively.This device comprises valve body, spool 4 and spring 3, and described spool 4 and spring 3 all are positioned at valve body, and spool 4 is slidingly fitted in the valve body.Described valve body comprises first valve body 5 and second valve body 7 that is threaded, and promptly is shaped on internal thread in first valve body 5, is shaped on outside thread on second valve body 7.All be shaped on second through hole 8 that has step type in first through hole, 2, the second valve bodies 7 that have step type in bamboo joint type joint 1, the first valve body 5 on described first valve body 5 and second valve body 7.
The threaded one end of described second valve body 7 is connected in first valve body 5, and described spring 3 is positioned at first through hole 2 of first valve body 5.Described spool 4 is divided into three sections, and first section pushes against with spring 3, and spool 4 intermediate sections and second valve body 7 are close to, the 3rd section second through hole 8 that is positioned at second valve body 7.The surface of contact of described spool 4 intermediate sections and second valve body 7 is an arc surface.The 3rd section cross section of described spool 4 is star, and such design makes spool 4 when not influencing its service behaviour, has played good reset guide effect.
The joint of described first valve body 5 and second valve body 7 also is provided with seal ring 6, and described seal ring 6 is positioned at externally threaded root on second valve body 7.
During this device busy, gas enters in second through hole 8 of second valve body 7 earlier, along with increasing of gas, air pressure in second through hole 8 increases, spool 4 intermediate sections and second valve body 7 are close to place's (being arc surface) to be backed down, this moment, spring 3 was compressive state, between the spool 4 and second valve body 7 passage was arranged.And then gas enters in first through hole 2 of first valve body 5 by this passage, and is transported to the desired position by the road.And after gas passed through smoothly, second through hole, 8 internal pressures descended, and resetted at the effect lower spring 3 of spring force, simultaneously spool 4 is resetted in the lump, this moment spool 4 intermediate section arc surface still and second valve body 8 be close to.At this moment, if gas makes the pressure of 4 pairs second valve bodies 8 of spool bigger, thereby makes sealing effect better when pouring in the other direction in the pipeline.
