Abstract
The utility model belongs to a valve, particularly a three-way valve used for heating pipelines. A T-shaped gas conveying passage is respectively arranged on a valve body and a valve core of the three-way valve, and T-shaped through holes are also distributed on the valve body and the valve core; therefore, when the three-way valve is installed on a three-fork between a main heating pipe and a branch pipeline of a user, the heating can be optionally stopped and supplied by rotating the valve core; the phenomena of steal gas and refusing to pay gas charge can be prevented by that a lock cover is arranged. The utility model has the advantages of small volume, easy operation, high safety, and convenient installation and modification.
Description
The utility model belongs to valve, specifically refers to a kind of three-way valve that is used on the caliduct.
Warming is a major issue in northerner's daily life, yet because the heating pipeline of residential building unit building adopts all necessary centralized and unified heating of which kind of connecting mode at present, like this when a user need stop using heating installation, will cause other user's heating installation of this unit to interrupt, make and produce contradiction between the user, can not arbitrarily stop the gas that heats according to user's requirement, make troubles to people's life.
The purpose of this utility model is to provide a kind of three-way valve, and it is installed on the place, junctions that heating installation main pipe and each service pipe connect, and can arbitrarily stop according to each user's requirement to heat gas and does not influence other user.
The purpose of this utility model is achieved in that a kind of three-way valve, it comprises valve body and spool, be provided with cavity in the valve body and be opened in "T"-shaped gas distribution channel on the cavity, spool is fitted to by the sealing gasket that has gland nut in the cavity of valve body, offers the distribution that matches with gas distribution channel on the spool and is "T"-shaped through hole.
Spool be shaped as taper shape or one of spherical.Be fitted with a locking closure on the valve body, valve body and locking closure inwall correspondence respectively offer the elastic collar groove, and elastic collar is positioned at the elastic collar groove.
Because three-way valve described in the utility model, offer "T"-shaped gas distribution channel on the cavity of valve body, spool is provided with the distribution that matches with gas distribution channel and is "T"-shaped through hole, during use it is installed on the place, junctions of heating installation main pipe and service pipe connection, when the user needs to use gas, rotary spool makes gas distribution channel all unimpeded, when the user did not need to use gas, the Rotate 180 degree can make bye-pass close again, main line is still unimpeded, so three-way valve can remain the unimpeded of main line heating pad passage, thereby can arbitrarily stop the gas that heats, and not influence other user according to customer requirements, solved the contradiction between the user, saved gas.Simultaneously in order to prevent that stealing gas or certain user without Qihu refuses to hand over situation such as heating installation expense to make troubles for the administrative staff's work of supplying gas, outside valve body, be equipped with locking closure, the spool arm pivot post is locked in the locking closure, general personnel are difficult to open, when the needs air feed, can open with special tool by the administrative staff that supply gas.This three-way valve volume is little, easy to operate, and safe and reliable being convenient to installed and reequiped.
Describe in detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model scheme of installation in pipeline.
As shown in Figure 1, a kind of three-way valve, comprise valve body 1 and spool 2, be provided with cavity 3 in the valve body 1 and be opened in "T"-shaped gas distribution channel 4 on the cavity 3, spool 2 is fitted in the cavity 3 by the sealing gasket 6 that has gland nut 5, offer the distribution that matches with gas distribution channel 4 on the spool 2 and be "T"-shaped through hole 7, spool 2 be shaped as taper, be fitted with a locking closure 8 on the valve body 1, on locking closure 8 inwalls and the valve body 1 respectively correspondence offer elastic collar groove 9, elastic collar is that a spring collar 10 is positioned at elastic collar groove 9, and elastic collar also can be chosen the rubber card circle.During use as shown in Figure 2, three-way valve is installed on heating installation main line 11 and service pipe 12 place, junctions that links, rotary spool 2 can make gas distribution channel 4 and through hole 7 all unimpeded when the user needs usefulness gas, when the user does not need to use gas, with spool 2 Rotate 180 degree, gas distribution channel 4 on the heating installation main line is still unimpeded at this moment, the gas distribution channel 4 that connects service pipe is closed, spring collar 10 is put in the elastic collar groove 9 on the valve body 1, again locking closure 8 is covered on valve body 1, the elastic collar groove 9 that spring collar 10 is positioned on locking closure 8 inwalls simultaneously locks in locking closure with the spool arm pivot post, when the user needs to use gas again again, can get final product with special TO locking closure 8 by the administrative staff that supply gas.
Claims (3)
1, a kind of three-way valve, it is characterized in that comprising valve body and spool, be provided with cavity in the valve body and be opened in "T"-shaped gas distribution channel on the cavity, spool is fitted to by the sealing gasket that has gland nut in the cavity of valve body, offers the distribution that matches with gas distribution channel on the spool and is "T"-shaped through hole.
2, a kind of three-way valve according to claim 1, what it is characterized in that spool is shaped as taper shape or one of spherical.
