The utility model discloses a car processing one shot forming, axiality and size are controlled easily, and are with low costs, can not have the burr to produce simultaneously, and overall structure intensity is high, and the card needle can not rock after multi-direction cartridge and the cartridge.
Description
Technical Field
The utility model belongs to the technical field of hanging stove valve body technique and specifically relates to a mouth of a river structure of metal valve body is related to.
Background
As shown in fig. 1 and 2, a metal valve body for a wall-hanging stove in the prior art comprises a water gap 111, wherein the water gap 111 is provided with two symmetrical grooves 112, and the grooves 112 penetrate through the inner wall and the outer wall of the water gap 111, which has the following problems:
the milling machine is required to mill two cutters for one and two slots 112, and errors are caused in secondary positioning.
Secondly, the size of the groove 112 is reduced after the water gap 111 is impacted.
And thirdly, referring to fig. 2, the installation can be carried out only by inserting the clamping pins in the left and right directions, the installation is not flexible enough, and the clamping pins are not stable enough after the insertion and can shake in the up and down directions.
Fourthly, the groove 112 is formed in a milling mode, burrs are formed on the edge of the groove 112, and the O-shaped ring can be broken in a squeezing mode during subsequent installation.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned prior art not enough, provide a mouth of a river structure of metal valve body, through car processing one shot forming, axiality and size are controlled easily, and are with low costs, can not have the burr to produce simultaneously, and overall structure intensity is high, and the card needle can not rock after multi-direction cartridge and the cartridge.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a mouth of a river structure of metal valve body, includes the mouth of a river, the mouth of a river is equipped with rather than concentric groove one, groove one is the design of whole circle, the outer wall of mouth of a river outwards extends and is equipped with the rib portion that circumference distributes, rib portion inner is equipped with groove two, groove two and groove one intercommunication.
The number of rib portions is four and the circumference equipartition, the outer end of rib portion is not run through to groove two.
The first groove comprises a part communicated with the second groove and a part penetrating through the inner wall and the outer wall of the water gap.
The inner wall of the water gap is provided with a chamfer which is positioned at the rear end of the groove I.
The metal valve body is a water outlet valve made of a copper material, and the water inlet is a water inlet.
The first groove and the second groove are formed in one step through turning.
The chamfer angle is 15 degrees.
The utility model has the advantages that:
the first groove, the first groove and the second groove are formed in one step through turning, a lathe is turned out, the coaxiality and the size are easy to control, the cost is low, and meanwhile, burrs cannot be generated (the O-shaped ring can be protected from being cut by the burrs).
And secondly, through the design of the four ribs, the strength of the first groove is increased, and the size of the first groove is not reduced due to collision.
Thirdly, the card needle can be followed four direction cartridge on upper and lower, left and right sides, and after the card needle cartridge, card needle both sides lie in groove two outer edges and support the rib portion, and the card needle can not rock like this.
And fourthly, the design of the chamfer angle is beneficial to the assembly of the copper connecting pipe.
Drawings
FIG. 1 is a perspective view of a prior art metal valve body;
FIG. 2 is a top view of a prior art metal valve body;
fig. 3 is a perspective view of the present invention;
fig. 4 is a top view of the present invention;
fig. 5 is a sectional view taken along the line a-a in fig. 4.
In the figure: the nozzle comprises a nozzle 1, a rib 2, a first groove 3, a second groove 4 and a chamfer 5.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 3 to 5, a water gap structure of a metal valve body includes a water gap 1, the metal valve body is a water outlet valve made of a copper material, the water gap 1 is a water inlet, and the water gap 1 is connected to a copper connection pipe. These are prior art.
The nozzle 1 is provided with a first groove 3 concentric with the nozzle, the first groove 3 is designed to be a whole circle, the outer wall of the nozzle 1 extends outwards to be provided with a rib part 2 distributed circumferentially, the inner end of the rib part 2 is provided with a second groove 4, and the second groove 4 is communicated with the first groove 3. The first groove 3 and the second groove 4 are formed in one step through turning, a lathe is turned out, the coaxiality and the size are easy to control, the cost is low, and meanwhile, burrs cannot be generated (the O-shaped ring can be protected from being cut by the burrs).
The number of the rib parts 2 is four, the rib parts are circumferentially and uniformly distributed, the strength of the first groove 3 is increased through the design of the four rib parts 2, and the size of the first groove 3 cannot be reduced due to collision. Meanwhile, the direction of the inserting needle is changed from the original two directions into four directions, and the inserting needle can be inserted from four directions, namely, the upper direction, the lower direction, the left direction and the right direction by taking the figure 4 as reference.
The second groove 4 does not extend through the outer end of the rib 2. After the clamping needle is inserted, the two sides of the clamping needle are positioned at the outer edge of the second groove 4 and abut against the rib part 2, so that the clamping needle cannot shake.
The first groove 3 comprises a part communicated with the second groove 4 and a part penetrating through the inner wall and the outer wall of the water gap 1.
The inner wall of the water gap 1 is provided with a chamfer 5, and the chamfer 5 is positioned at the rear end of the first groove 3. The chamfer angle 5 is 15 degrees, and the design of the chamfer angle 5 is beneficial to the assembly of the copper connecting pipe.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
