Abstract
The utility model provides a combined ball valve with filter, sewage discharging and safety decompression functions, the filter screen that sets up in the inside passage of ball valve, blowoff valve, relief valve and valve body slant interface, its characterized in that: after the sealing washer was connected relatively to the ball valve element both sides that set up in the valve pocket of ball valve, being intake by the ball valve, to set up the lock nut locking positioning of spiro union fixed in end passageway one side, the ball valve intake the end passway be provided with with the siamesed threaded joint of valve body, threaded joint is last to join in marriage the needs that connect according to the pipeline, can select to connect the not transition of isostructure and join in marriage connect pipe joint. The utility model discloses a combination ball valve, still has the reliability of use height and joins in marriage the nimble characteristics that connect with the installation in the function of an organic whole except that collecting on and off control, filtration blowdown and safe pressure release.
Description
Technical field
The utility model relates to a kind of ball valve, specifically refers to that being contained in tap water registers one's residence front end, controls a kind of of house delivery (pipe) line and has for opening and closing the Combined ball valve filtering blowdown and safety relief function.
Background technique
Tap water is equipped with in front end of registering one's residence for controlling valve that house delivery (pipe) line opens and closes also known as feed valve, usually adopts ball valve or gate valve; In order to prevent outstanding mixed silt in tap water from entering user, also need filtration blowdown valve is housed; In addition, in order to suppress the water hammer effect in delivery (pipe) line also to need to install safety relief valve additional in addition; The feed valve of prior art, filter blowdown valve and safety relief valve is separate and different types of piping installation of function singleness, need during application to install respectively to be separately connected on hot-water heating pipeline, also need to set up tee pipe fitting in addition, cause the cost up of hot-water heating pipeline, construction and installation bother; Therefore, there are time-consuming, that cost is high problems and shortcomings in prior art.
In order to solve above prior art Problems existing, our company at first patent application Chinese utility model patent application number: " 201220666722.7 ", disclose " a kind of Combined ball valve with filtration blowdown and safety relief function ", ball valve, filtration blowdown valve, safety relief valve organically combine by this Combined ball valve, make a valve play the action effect of three valves simultaneously, and, installation convenience, saving of work and time, reduce cost.But, this Combined ball valve also exposes a problem in actual use, be exactly ball valve part structural design on there is irrational place, shown in Figure 7, the ball valve core a2 side of ball valve be rely on O-ring seal a3 and the feed-water end joint a4 that is spirally connected with valve body a1 fixing to locate, during use, with pipeline connect construct or pipeline maintenance in the threaded joint of feed-water end joint a4 and valve body a1 easily cause loosening, the sealing affecting ball valve is even damaged, and whole Combined ball valve cannot be used.
Model utility content
Technical problem to be solved in the utility model is the deficiency existed for prior art, and provides a kind of ball valve core positioning and fixing structure of the ball valve part to Combined ball valve to carry out correcting the Combined ball valve with filtration blowdown and safety relief function of design.
The technological scheme that the utility model adopts is: a kind of have the Combined ball valve filtering blowdown and safety relief function, comprise the filter screen arranged in the inner passage of the oblique interface of ball valve, blowdown valve, safety valve and valve body, it is characterized in that: after the ball valve core both sides arranged in the valve pocket of described ball valve connect seal ring relatively, arrange by ball valve feed-water end passage side the locking nut locking and positioning be spirally connected to fix, the feed-water end passway of described ball valve is provided with the pipe screw joint with valve body disjunctor.
Further, described locking nut is provided with notch portion by seal ring side, and notch portion and seal ring outer circumferential face are connected.
Further, described pipe screw joint is Internal Pipe Thread joint.
Further, described pipe screw joint is external pipe thread joint.
Further, the pipe screw joint of described ball valve is also connected with welded stub connection.
Further, the pipe screw joint of described ball valve is also connected with female union.
Further, the pipe screw joint of described ball valve is also connected with male connector.
With our company compared with the first patent application, the utility model has the advantage of: the ball valve core positioning and fixing structure due to the ball valve part to Combined ball valve formerly carries out correction design, the feed-water end joint of the ball valve part of Combined ball valve and valve body are connected as a single entity, ball valve core change located by the locking nut be spirally connected separately with valve body fixing, and the transition adapting pipe joint devising three kinds of different structures can be connected with feed-water end joint.Make Combined ball valve of the present utility model except the keying control keeping original Combined ball valve to have, filtration blowdown and safety relief are except the function of one, the reliability used obtains further raising, simultaneously, at the needs that actual use occasion user can connect according to pipeline, select the Combined ball valve being connected to the transition adapting pipe joint of different structure, add the flexibility of use.

Embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1 ~ Fig. 3, a kind of Combined ball valve with filtration blowdown and safety relief function of the present utility model, comprise the filter screen 4 arranged in the inner passage of ball valve 1, blowdown valve 2, safety valve 3 and the oblique interface of valve body, it is characterized in that: after ball valve core 11 both sides arranged in the valve pocket of described ball valve 1 connect seal ring 12 relatively, arrange by ball valve 1 feed-water end passage side locking nut 13 locking and positioning be spirally connected to fix, locking nut 13 is provided with notch portion 131 by seal ring 12 side, and notch portion and seal ring outer circumferential face are connected; The feed-water end passway of described ball valve 1 is provided with the pipe screw joint 14 with valve body disjunctor, and the structure of pipe screw joint 14 can be set to Internal Pipe Thread joint or external pipe thread joint form, and the present embodiment is Internal Pipe Thread joint form.For adapting to the needs that actual use occasion pipeline connects, the transition adapting pipe joint devising three kinds of different structures is connected with feed-water end pipe screw joint, as shown in Figure 4, give a kind of Combined ball valve with filtration blowdown and safety relief function being connected with welded stub connection 15, when using installation, be suitable for the occasion be welded to connect with pipeline; As shown in figs. 5 and 6, sets forth a kind of Combined ball valve with filtration blowdown and safety relief function being connected with female union 16 and male connector 17, when using installation, be suitable for being spirally connected with pipeline the occasion be connected.The transition adapting pipe joint of described above-mentioned three kinds of different structures and the inner side at pipe screw joint 14 place of being spirally connected also are provided with O-ring seal 18, ensure that the sealing of interface.
