Abstract
The utility model belongs to the technical field of pipe and valve control components of fluid channels, and relates to a decompression valve. The decompression valve comprises a valve body provided with a water inlet and a water outlet, a decompression bypass branches off from a main channel from the water inlet to the water outlet of the valve body, wherein the bypass passes by a decompression spool assembly to a decompression water outlet, a partition board is arranged in the main channel, wherein the spool locating hole is formed in the center of the main channel. An inner row device comprising the spool and a flat gasket is arranged in the main channel, the water inlet is embedded into a locating embedded part with the inner end butting against the flat gasket, and the inner end of the locating embedded part is provided with a step hole containing the outer end of the spool and limits in the axial direction. The decompression valve properly solves the locating problem of the spool, can remove a locating sleeve, and avoids the shaking phenomena along with fed water, ensures stability of the spool and a water feeding spring, and further ensures stable performance.
Description
Technical field
The utility model relates to a kind of valve, and especially a kind of Decompression valves belongs to fluid channel tube valve control spare technical field.
Background technique
Decompression valves is the device pipe valve control meanss commonly used such as water heater, and its effect is the pipeline that automatic unlatching was originally closed when system pressure is too high, and release pressure plays the safety protection effect.The typical structure of existing Decompression valves such as application number are disclosed by 200920295257.9 Chinese patent.Investigate understanding according to the claimant, there is following shortcoming in this type of Decompression valves:
1) setting sleeve lacks axial limiting calmly, can rock along with water inlet, thereby cause the unstable of spool and water inlet spring;
2) because inner chamber is less, easily produce resonance when interior arranging device and valve body collision, make a noise;
3) the valve body water outlet is connected with the fill hose joint of water heater by internal thread, because the fill hose joint of valve body and water heater can corrode gradually, therefore causes unavoidably the water heater joint to leak.
The model utility content
The purpose of this utility model is: the problem for above-mentioned prior art exists proposes a kind of stable performance, can avoid the Decompression valves of water clock.
In order to reach above purpose, Decompression valves of the present utility model comprises the valve body with water intake and water outlet, described valve body branches out the pressure release bypass of leading to the pressure release water outlet through the pressure releasing valve core assembly by water intake to the primary path of water outlet, the dividing plate that the center has the spool positioning hole is set in the described primary path, the interior arranging device that contains spool and flat gasket is housed in the described primary path, described water intake embeds inner location inserts against flat gasket, and the inner of described location inserts has the step hole that holds spool outer end and axial limiting.Like this, properly settle the orientation problem of spool, can cancel setting sleeve, avoided occurring with the water inlet shaking phenomenon, guaranteed the stable of spool and water inlet spring, and then guaranteed the stable performance of Decompression valves.
The utility model further improves, described interior arranging device mainly is comprised of spool, flat gasket, spring seat and stage clip, described spool consists of by the end plate of outer end with from the extended valve rod in end plate center, the termination of described valve rod penetrates in the described spool positioning hole, the flat gasket of described end plate place installation sleeve on valve rod, the water inlet spring of installation sleeve on valve rod between described dividing plate and the flat gasket, the spring seat of installation sleeve on valve rod on the described flat gasket is equipped with the stage clip that an end is constrained in valve rod in the described spring seat.
The utility model further improves, and described flat gasket adopts elastic material to make, and is plum blossom-shaped, and periphery is provided with at least two projections, thereby forms the water inlet gap, can avoid interior arranging device and valve body bump simultaneously, suppresses to produce noise.
The utility model further improves, uniform at least two boss of described valve rod cylindrical, thus form backflow gap, protection water heater liner, and the reverse seal action when playing stopping running water.
It is between described location inserts and the described water intake Sealing to be housed, thereby can effectively to avoid water clock that the utility model further improves again.

Embodiment
Embodiment one
Present embodiment is a kind of Decompression valves that is applied to water heater, its basic structure as shown in Figure 1, comprise the valve body 1 with water intake and water outlet, this valve body branches out the pressure release bypass of leading to the pressure release water outlet through the pressure releasing valve core assembly by water intake to the primary path of water outlet.The pressure releasing valve core assembly is same as the prior art, mainly is made of pull bar 12, pressure relief sealing ring 13, pressure release sealing gasket 14, stainless steel gasket 15, Sealing shield ring 17, handle 18, clamping cap 19, pressure release spring 20, rubber seat 21.The dividing plate that the center has the spool positioning hole is set in the primary path, the interior arranging device that contains spool 7 and flat gasket 5 is housed in the primary path, water intake embeds inner location inserts 2 against flat gasket 5, and the inner of this location inserts has the step hole that holds spool 7 outer ends and axial limiting.The interior arranging device of present embodiment is comprised of spool 7, flat gasket 5, spring seat 4 and stage clip 8.Spool consists of by the end plate of outer end with from the extended valve rod in end plate center, and the termination of valve rod penetrates in the spool positioning hole of dividing plate.The flat gasket 5 of end plate place installation sleeve on valve rod, the water inlet spring 6 of installation sleeve on valve rod between dividing plate and the flat gasket 5, the spring seat 4 of installation sleeve on valve rod is equipped with the stage clip 8 that an end is constrained in valve rod on the flat gasket 5 in the spring seat 4.Flat gasket 5 adopts elastic material to make, and as shown in Figure 2, is plum blossom-shaped, and periphery is provided with six semicircular projections 5-1.The valve rod cylindrical of spool 7 as shown in Figure 3, uniform six boss 7-1.Between location inserts 2 and the water intake O RunddichtringO 3 is housed.
Evidence, present embodiment have solved the problem that prior art exists, and have produced obvious effect, have following structural feature:
1) setting sleeve that will locate water inlet spring and spool changes into and being arranged in the valve body and the integrated positioning hole of valve body, spring is located by the water-inlet cavity inwall, therefore fixing spring that can be more stable and the position of spool cause spring and the spool unsettled drawback that leads because of water impact when having solved traditional setting sleeve fixing spring and spool easily.
2) therefore be provided with a plurality of projections at flat gasket, owing to smooth material that adopts elastically deformable can avoid interior arranging device and valve body bump and generation sound.
3) pressure release water outlet and valve body are one-body molded, have cancelled originally being threaded connection and with the mode of O type circle sealing, having reduced the risk of leaking.
